Cars that are US spec and have the additional carbon filter for the fuel tank or are the 4wd model use a different Navigation unit thats vertically mounted in the front trunk. As I tried to describe in earlier posts , the MOST ring is directional , so there is an IN and an OUT on the plug that goes into the rear of each device. Having installed the very same (dual FOT) dension myself I'm aware that when fitting the unit with a change over switch , the fibre optic cables need to be altered from those of standard. Simply unplugging the dension isnt going to help , as the loop wiring is modified to allow the CD changer and Dension to sit side by side. You will need to identify the original cable from the PCM and plug this into the CD changer and then connect this to the nav which then in turn connects back to the PCM. Its difficult to explain in words , but if you download the user install guide from dension .com it has a diagram that makes better sense. I dont beleive this is the root cause of your stuck DVD in the nav drive, I suspect its more a case of the disc being the wrong way up, the wrong type or incompatable software with the rest of the system. I know of a couple of other cases where the disc became "stuck" in the nav drive , none were able to eject it and ended up with a new drive. The Navi drive should be able to eject the disc , even with the main PCM off , therefore I'd suggest that removing the power to the rear of the nav and holding the eject button when reconnecting (after a few minutes ) may be the only possible solution. What seems stange in this particular case is that the CD and nav are in different places to expected. Furthermore the PCM doesn't display a "target" value for the navigation. The target is configured using the PWIS and held in the gateway of the car. The navigation option is not standard with PCM on the 997 , so it may be that this is a later addition. When coding the new navi drive , if the car isnt subject to a vehicle handover procedure , the updated setting (ie the the nav) can be lost if the power is disconnected from the battery. Is it possible that the nav was fitted afterward and either incorrectly placed in the MOST loop or never coded ? The nav units have different codes for vertical versus horizontal mount , so incorrect installation may well cause issues. A look at the vehicle options codes in the front of your owners sevice book will validate if this was factory fittment or added later. The first pic shows the 997 TT which is 4wd , as you can see the DVD drive has two possible locations each of which has a separate part number , the CD drive in this case is fitted vertically also. The second pic shows the Gt3 which has the option for either a vertical or horizontal DVD drive. The CD changer on most 997 is normally a horizontal mount.

There is a rubber grommet just to the right of the battery. Make a smal hole with a knitting needle or bradawl and thread the wire through. It comes out the other side in the drivers footwell to the top right of the cutch pedal , you may need to peel the carpet back a little to see it. Then you can run the cable under the edge of the centre console up to the center armrest or cubby storage.

Like most people , I have the PSE active all the time. The beauty of the bypass switch is it allows you to revert to quiet mode when returning home late or those times when perhaps you want a low profile with the local police. Its a clean and non traceable way to activate and de activate the PSE that can be simply switched come time for a service. Hiding the switch in the ashtray, its unlikely any but the most astute porsche tech would notice ther eis anything non standard. The switch is also a very cost effective way to get PSE control for those retro fitting a PSE that do not have sport chrono and would otherwise require additional wiring and a new switch panel.

I carry a 986 space saver (with jack and tools) in the front boot rather than have the hassle of using the tyre sealant. Rolling radius isnt exact as the 987/997 is bigger than the 986/996 but with PSM off its enough to get you to the tyre shop for a decent repair. The space saver is pre inflated type so no fiddling with pumping it up at the roadside. Spare can go on passenger seat (porsche can supply a plastic bag for about 2 uk pounds or 3 USD ) or in my case I've made up a rubber mat for the top of the rear trunk and some straps to seucre it.

The CD changer and NAVI drive are in sequence on the MOST ring so the connections very close to each other. Is it possible when the i pod interface was being installed the wrong MOST cable was taken out of the rear of the DVD Navi rather than CD changer ? The I pod interface mimics the Cd changer so it must replace the CD changer in the loop. Dension offer a switched interface whereby the CD chnager can remain connected and via a switch on the aux input module you toggle between dension or original CD changer. The MOST cables are also directional , so when you fit a new device there is an IN and an OUT most fibre optic to the unit. If you look closely at the plug you can see a direction arrow. The MOST connectors come in two forms , one is pre wired , the other is user assembled , as a result its possible to get the wires in the wrong chambers and directions incorrect. The OUT wire from one device should correspond to the IN wire on the next device in the sequence etc.

The PSE will make a different sound depending on the load on the engine , when on the overrun you get less of a boom but more crackles and pops , when under load climbing a hill the engine works harder and you get a deeper more agressive note. Under steady state cruising with light throttle the exhuast can almost become as unobtrusive as the standard item. Wind the revs above 5k and you get a loud agressive bark. Regarding the activation of the PSE , I made up a custom loom to allow a simple switch to activate and de activate the PSE without the DME overide between 20 and 40 mph. If you are activating the PSE via the SPORT button currently , the bypass switch allows you to have the PSE always active without the need to reset every time you start the car . It also allows the PSE to be active without the sport mapping of the throttle and PSM. The loom I made is plug and play , so you dont need to modify any of the existing wiring , making it completely reversible. The switch can be mounted under the handbrake or inside the ash tray.

As suggested you need to check the navigation and PCM software versions are compatable and the disc is correct for the software versions. Start by pressing the MAIN and TRIP buttons together and then write down the software version displayed on the top header bar and then select each of the displayed components to reveal its individual actual and target software. If you can post these back on hte forum we can give you a better idea of where the problem may lie. To reset the PCM/ NAV you can either remove the fuse or press 1 , 4 and 8 buttons simultaneously. If it gets to the point of replacing the PCM , you would be better to consider an aftermarket head unit with navigation from Kenwood or Pioneer. Not only are the navigation updates cheaper and more readily available , but the unit will have bluetooth connectivity and MP3 functions already built in , rather than expensive add ons as with the PCM. With aftermarket fascias available and custom welcome screens , its easy to get a very authentic looking install that woul fool all but the porsche techs.

If you press MAIN and TRIP buttons together you get a service menu displayed. Each of the items on the MOST (fibre optic) ring is displayed with a target and actual value. If there are items in the wrong sequence or with faults there will be a warning triangle next to the device and missing parameters. Typically if an item is incorrectly installed in the loop it affects other devices as well , as there is a set sequence for each control item ( CD , NAV, TEL etc) that must be followed. If the Navigation unit isn't showing a fault on this menu , then its correctly located on the MOST loop. The Navigation unit DVD drive has permanent power , whereas the MOST loop is only functional when the PCM is active since this is the hub for the system. Therefore ejecting the DVD should not be dependent on the MOST loop being active. There is a small paper guide located on the inside of the fuse box cover in the forrwell. This explains the location of the fuse for the PCM and navigation DVD drive. If you pull the fuse , allow a few minutes before re instating and then press and hold the DVD eject on the NAvi DVD player you may have some success.

Sounds like someone got the CD changer and Navi mixed up and put a CD in the DVD drive or put an old version map DVD in the unit before selling. The DVD unit has permanent power and a wake up from the PCM. All I can suggest is holding the eject button whilst re instating power to the DVD drive by replacing the plug, you may be fortunate that this allows the unit to give up the disc. I've had a few close calls with the PCM where an incompatable disc has become "locked " in the drive. In most cases a bit of patience has paid off where the disc ejected after holding in the eject on power up. There is also a reset procedure you can try which involves pressing and holding 1 4 8 together. Porsche approach will be labour and parts to fit a new DVD drive.

I don't think the difference in weight is going to make any difference unless you are at the top of your game in track driving. For the road its better to go with a wheel thats practical to keep clean. Bear in mind also that 19" tyres are more expensive (and often more difficult to obtain) than 18" equivalents of the same width. If you like the gunmetal look , have you considered the carrera sport wheel , this is wider than the other wheels you have listed at 8.5 Front and 10 rear, with a bigger offset, though uses the same tyre widths. The result is the wheel and tyre fill the arches better and the increased track width will improve cornering grip and reduce roll. The standard wheel colour on most wheels is Gt silver I believe , so already a shade darker than the arctic silver you already have on the rest of the car.

I've retrofitted quite a few options to my own car. The biggest stumbling block is usually the plugs on the end of the wiring. You can buy the sensors and the control unit , but these will have moulded sockets to accept specific plugs. You need to do some research on alternative suppliers for the correct plugs ( VW/ Audi as a start) as in most cases its not possible to simply buy a retro fit mini loom with all the plugs attached. My first suggestion is check the obvious with your local porsche dealer that a tequipment parking kit isnt available. If it isnt , then find out the option code for parking sensors and do a search for all parts in PET (porsche parts catalogue) matching that option code, this gives a kit of parts to buy. Next you will need a wiring diagram and someone with some mechanical and electrical skill to fit the parts , cables and wires. The final part is getting the workshop tool connected (not duarametric) and having the parking option enabled.

Try pressing 148 all together at the same time and then press and hold the eject button on the PCM.

Are we talking about the hi beam driving light or the sidelight DRL units here? I have a blue tinted hi beam bulb in my 987 with xenon headlamps which matches the xenon gas discharge colour very well. The DRL or sidelight bulbs I used are LED items with built in resistors so they dont throw bulb errors. The blue tint on the hi beam is similar coating to that found on the OEM supplied phillips vision sidelight w5 bulbs. You get no loss or gain in vision using these bulbs just a different light colour. Hi beam active with standard bulbs in xenon headlamp Hi Beam active with exra white (blue tint) bulbs in xenon headlamp Bulb in headlmap unit . You can make out the blue tint

Ideally use aluminium paste rather than copper based as it doesnt dry out and is better for reducing galvanic reaction. Porsche do seel optimoly paste but its about 20 uk pounds a tube. Thats where I got mine from. Its listed in the parts catalogue in the brakes section.

I've only ever seen the boxster/ cayman exhaust cut open , to compare with the PSE. Assuming its the same principle on the 997 as the 987 there is a bypass tube already in the silencer, all Eisenmann do is introduce a valve and remove the reducer at the other end of the existing tube so you get a fuller sound on bypass . There are a few companies such as carnewal that offer exhange mufflers which have the internals mofified to give a similar sound , though its not switchable. Since the mufflers are stainless steel , one option is to pick up a used set on e bay , this is what I did for my 987 , saving about 1000 Uk pounds in the process.

The profile of the plastic seems to suggest it is located into foam as it has some spikes on the rear. Now all I need to do is work out where it fits and what tools fit into it. I'm thinking it will be the wheel hangar that paulspeed mentioned and the screwdriver. I will post a pic once I've figured it out. Thanks again

There is avery good write up on retro fitting the PCM on both www.planetporsche.net (US based) and www.boxa.net (UK based). The Bose amplifer on a 987 fits in the front luggage compartment and is hidden by the panel that the warning triangle sit on top of. There are two plastic quarter turn screws that hold the panel in place, the amp sits behind the panel. As I'm sure you are aware there are different MOST fibre optic cable options depending on the components fitted to your car. You will need the MOST cable suitable for a car with BOSE and Navigation as the cables are different lengths . It's also important that you connect the devices in the correct order , as the MOST loop is a ring circuit and each device has a designated position in the sequence. Each device has an IN and and OUT cable that needs to be connected to the correct device in the sequence prior and after , if the sequence is incorrect the device will not be recognised and the whole loop can malfunction. I assume that you have matched the PCM version to the navigation DVD drive as these have different hardware and software levels. If you have any more questions drop me a line.

Does your car also have PCM? Have you checked the audio pilot is on or off ?

I have purchased a 987/ 997 space saver (185/ 60 /17 collapsable tyre on 5.5 inch rim) and the foam insert to store it in the car. Also listed for the space saver " kit " is a plastic insert 997 722 801 00 described as "mounting for tool" . Does anyone know where this part fits , and what tools are supposed to locate in it ? Is it suppsed to go in the front trunk or in the foam insert that holds the jack ? Thanks. Here is the plastic insert Here is the wheel located in the foam insert on my 987. The foam insert is different on the 997 as it locates on the rear seat. There is also an insert that contains the jack and jack handle that sits inside the wheel. This is the same part as used on the earlier 986 / 996 Boxster / 911

Porsche state in the manual that there is only one 12V socket on the car capable of plugging the tyre inflator into, the one in the cigarette lighter. All the others have too low fuse ratings . Daft I know.

Cassiebox, Your PCM is a later level C version so it doesnt need any updates to run with a 2007 or 2009 map DVD other than the navigation drive to be updated to software level 00179436/3306. The software cannot be updated on later cars , the software levels you posted look correct for the year of car you have. To do the navigation update you need the " PCM 2.1 multimedia update CD Navigation MY08 part no 000 044 901 40" loaded into the navigation DVD drive with the engine and PCM switched off. Wait about 1 min before starting the engine and powering on the PCM, then select nav and accept the screen prompt to update the navigation system. Wait for the update to complete , which usually ends in an error saying there is no navigation CD. Then turn off the PCM and engine , wait 2 mins before ejecting the CD from the DVD drive , then insert the 2009 map DVD , wait another min before starting the engine and PCM again. Then select the Nav screen and again accept the prompt to load new maps. After the update , the map is displayed and the navigation is active , ready to accept a new destination. The nav software level should be at the level I described above.

PASM has undergone a number of revisions since first introduction. The part number suffix on the PASM damper has progressed from 04 to 20 suggsting 16 revisions. Having recently replaced the rear PASM dampers on my own car (987S boxster 2004) due to an annoying rattle and poor damping, I can confirm the newer dampers are much less harsh in sport mode than original. I've also driven a cayman gen 2 with similar 19" wheels to my own car , but with standard suspension and found the ride quality over broken tarmac to be comparable to my PASM equipped car in normal mode. If you prefer the handling of your car to be progressive I would suggest the standard suspension would be better , as the PASM has no fewer than 5 settings in each mode , which constantly adjust under load and speed.

If you plan to update to the newer maps yourself here is the information you should be aware of : The 2007 and 2009 map DVD requires a new level of navigation software to run on any PCM 2.1 (cayenne, boxster , 911 , cayman) The TSB from porsche clearly states that the multimedia update CD must be insterted into the navigation DVD drive , to update the navigation software , BEFORE the new map DVD (applies to both 2007 and 2009 versions) can be used. The issue is not with the PCM software , but the navigation drive software. The navigation drive used in the cayenne is the same as the 911 and boxster so the update CD is the same part number. I have plenty of experience updating PCM 2.1 units and this is always the case. The only times that the use of the multimedia update CD can be avoided , is when the navigation unit has been updated with all four bi yearly updates from 2005 through to 2006. The navigation software used on the 2007 and 2009 map DVD is the same as that provided on the self updating map DVD in late 2006. The simplest and most sure fire way of loading the 2007 or 2009 map DVD is to use the prescribed software from porsche (multimedia update CD) in the correct method outlined in the TSB. The update multimedia CD is not available separately from porsche , so you need to contact someone that already has one and borrow it. Alternatively you could go to your local OPC and ask porsche to supply the map DVD and updates and install them for you.

The valves that control the exhaust are powered to close the bypass ie make the exhaust quiet. If its wired anything like the later 997/ 987 , then the switch on the dash is a momentary pushbutton which sends a signal to the rear ECU (DME) control unit . This unit internally switches the PSE on an off. The DME connects to the solenoid valve on one side of its two terminals (switching to ground when the dash switch is pressed) the other terminal has a power feed +12V . If you want to control the PSE as porsche intended , you will probably need the switch on the dash plus coding of the rear DME , then you would need to add the wiring from the DME to the solenoid control valve for the vacuum. You would also need to pick up a live feed for the other side of the solenoid if the fitting kit wiring loom didnt include this part. I retro fitted a fully operational PSE to my 2005 MY 987S , but needed to add some wiring for the solenoid myself , as there was no kit available. Basically it was a wire from C14 of the DME to the PSE solenoid and a live feed to the other side. Since I already had sport chrono I didnt need to add the wiring from the dash to the DME. After wiring up the car needed to be coded for the PSE option to allow the rear ECU (DME) to activate the terminal C14 to switch the PSE on and off.

I've not seen any reports on forums of IMS bearing / shaft failure for the M97 engine (fitted post 2006) where did you see these failures JFP , what were the failures , shaft or bearing ? ?
