I beleive shell helix is also 5W40. The diesel oils contain higher levels of surfactancts (cleanaing agents). Probaly not a bad idea to join the contributing members and look over the TSB section for porsche approved oils. There are about twenty approved suppliers each with a number of options.

The PCM like other devices sits on a CAN bus, thats how the PWIS communicates with it. Each device on the CAN network will have a particular address or number that is specific to that type of device hard coded into it. If you plug a device that has a coding the same as another device it will throw a fault on the CAN network as two devices with the same number are seen. If the PCM you have fitted was a PCM 2 its possible the CAN address for the PCM 2 on a 986 uses the same address as PASM or PSM on the 987 , hence you get a fault. The PCM 2 and 2.1 can easilly be confused as they have similar size and layout. What is the part number on the side of the PCM, it should start with 997 xxxxxxxxx . The 987 wiring loom is identical as far as plug connections are concerned between the CDR unit and PCM , therefore the units can be plugged in and work straight away. Coding using the PWIS ensures that the attached devices (such as telephone, bose, CD changer etc) work properly.

ZUNSPORT do a chrome or black mesh grille in stainless steel that fits over the front plastic grilles. I made up my own grilles to sit behind the front intake slats from black aluminium mesh. These were fitted from the front of the car without the need to remove any trim or bumper covers. If you want to take out the from intake slats you need to remove the bumper cover. There is a thread on the subject with pictures over on boxa.net

I think the sunroof is coded in the rear control module. From my experience with the alarm system ( also coded in the rear control module) the functionality is set by the country coding ie the siren duration, reset time etc. Is it possible the counrty coding may allow comfort closure for some countries but not others ? Just an idea.

Installation now complete and fully functional. The PSE silencers (mufflers) are a direct fittment onto the 987S manifolds. The vacuum tubing and control valves have been retro fitted , all parts obtained from my local porsche agent as spare parts. The only difficult parts to obtain were the plug for the solenoid valve and the connection pin for the plug on the rear DME. These must be sourced from a VW dealership as spare parts. Just to recap , this is a fully operational PSE fitted to a MY2005 987S. The vehicle did not have the PSE control wiring originally installed , this has all been retrofitted by myself. There is a TSB on this forum that will give more details for the wiring of the control switch , the switch panel with PSE button can be bought as a spare part , then its just a case of wiring back to the rear DME as described. The PSE solenoid is activated by pin C14 on MY2005 cars, the other side of the solenoid is connected to a Red/Blue wire on Pin A8 which is permanently live. The PSE is controlled by the SPORT button from the front switch panel ( my car has sport chrono) but unlike the later 2007 models , the PSE remains active regardless of road speed. To get the PSE operational it must be enabled via the PWIS unit in the gateway module. I have also installed a manual override switch to allow the PSE to be activated regardles of the sport button , so the PSE can be switched to being permanently active. :clapping: For anyone considering buying a sports exhaust for the added sound, I can reccommend this item. Not only do you get the benefits of the sportier tone , but you also have the ability to revert back to a quiet mode for motorway journies , or when at trackdays all at the touch of a button. Ok... there is no performance gain, but the system is emissions compliant and a great enhancement to the car. From what ive experienced so far , retro fitting the PSE to a MY 2005 car actually results in a better system than that of the Rs60 as the exhaust has no added software controlling its operation below 40 mph. A few words of thanks to : Porsche librarian, Loren, Wizard, and Richard Hamilton for all their help and support.

Install on my MY2005 987S is now finished and fully operational. The PSE is controlled by the SPORT button that activates the optional sport chrono package. The PSE switches to "loud" as a result of the "sport" function being active. Unlike the MY2007 vehicles the PSE is not switched off below 40 mph and stays active regardless of speed. The wiring to the rear DME for the PSE solenoid uses a different pin location on early cars , suggesting the noise abatement function found on MY2007 cars is the result of a different control module DME unit and switching control. I have also installed an ovveride switch to allow the PSE to be controlled regardless of the sport button. The overide switch can be installed on any PSE equipped vehicle and will allow the PSE to remain active regardless of speed.

I was under the impression that only the shoulder and manual side bolster adjustments were in addition on the sport to the standard memory seats. The bottom seat squab is adjustable in both the standard and sport electic seats, so I would be surprised if its different. The seat module may be different but if it's included with the seat , it should just be a simple job of recoding. As suggested above I would check the PET catalogue in relation to the seat control module for the two types of seat , especially if its not included with the new seat. The fitting points should be the same.

The outlet tips are the only difference between the RS60 and the standard or PSE item. No performance or sound improvements from the dual tips , its just purely a styling thing. The RS60 tips can be bought from Suncoast or your local Porsche center.

There is a set sequence for interfaces on the MOST loop. The Dension unit will need to be in series with the Nav unit and from memory will fit in place after the navigation system. The MOST connectors have arrows on the end of the plugs so you see if the connection is the input or the output from the device. The dension fitting instructions are very good and will explain more.

Update : System now installed and a manual change over switch placed in the circuit to allow driver control of the system. Interestingly the PSE exhaust is actually quieter than the standard exhaust when in quiet mode. I like the sound of the exhuast when switched to loud mode and the flexibility to revert back to quiet when conditions require. Definitely an addition worth doing if you require a more sporty sound but not sure if you can live with a loud exhaust on a daily basis. It will also pass any emission controls without issue , so added peace of mind.

Which unit you go for depends on what hardware you are using. If you are a mac devotee then the mobridge device is specifically designed to synch with mac products , ipod, i phone etc. If you plan on using a USB memory stick or an alternative bluetooth phone then the dension product would get my vote as its well supported with updates and more flexible to alternative hardware. Virtually all these add on devices work by fitting in place of the original CD changer on the MOST loop , so your PCM will need to be coded as if it has a CD changer. If you have a Cd changer it should sit on top of the DVD navigation drive in the front trunk.The dension unit emulates the PCM phone device allowing the pcm to hold phone book lists and data.

There is no rhyme or reason to the type of IMS bearing fitted to an engine. I have a MY2005 987 , the parts catalogue suggests for the engine number , my car should have the later single row bearing and 10mm shaft. In reality it has the earlier single row bearing and 8mm shaft . I know this because the IMS bearing cover was replaced with the clutch and the original part sent by porsche was for the later version (as paer the parts listing) and didn't fit. The double rwo bearing was fitted to early 986 /996 engines , thereafter the single row bearing took over with initially an 8mm shaft , then latterly a 10mm shaft and more substantial bearing. The bearing covers are different both in bore size and depth , between the two versions of single row bearing. The early single row bearings (held with a circlip) are thinner cross section , so the covers are deeper. One type of the single row bearing is retained by a circlip , only this variant can be replaced in situ without the engine requiring removal and disassembly. Double row and non circlip single row bearings require the engine out and strip down to be replaced.

providing its the same platform ie a pcm 2.1 the discs will work in a USA vehicle.

Correct me if I'm wrong , but is the camshaft adjustment not hydraulically actuated by the engine oil via a shuttle valve ? Could the issue be a restriction in the oilway following the oil being drained preventing the camshaft returning to its usual home position ? Maybe an engine flush and refill may solve the problem. Certainly a lot cheaper option to try before a major strip down.

Porsche libranian is a great help with all technical info and documentation you may require.

I think the removal of the steering wheel has already been covered in the 997 forum. The airbag is held in place by 3 sprung clips which are released by pushing at a central point on the spring through the hole in the rear of the wheel. I found that using a thin bladed screwdriver with a long shank allowed the spring to be released. You need to position the blade of the driver so it is across the spring so the blade must be in line with the axis of the car. Before you remove the airbag make sure the battery is disconnected and that the key is in the ignition.

Definitely not right....Is this a brand new PCM 2.1 supplied by the Porsche dealer or one you picked up second hand ? Just to check it should be a PCM 2.1 in a 987 boxster , not a PCM 2.

if its a 2004 model it may be either the PCM 2.1 which is DVD based or the PCM 2.0 which is CD based. Does the map you have currently include all of europe or just the UK ? If it does more than just the UK chances are its a PCM 2.1. If you press the MAIN anbd TRIP buttons the software levels are displayed.

There are two types of PCM. Those for bose equipped cars and those without bose. The PCM units that are non bose will still work with the soundpack amplifier as it takes the signal from the speaker outputs. The BOSE equipped PCM s do not have the speaker outputs enabled , it uses the MOST link to send the signal to the BOSE amp to which the speakers are connected. Better to buy the correct PCM for your car than try and re engineer or reconfigure the unit.

There was some data collection done over on Boxa net regarding IMS failures. Ok it wasnt a full listing of all the IMS failures recorded , but of the occasions identified it seemed to pan out to a 30 to 40K figure. I agree that this isn't a basis for a statement that all IMS failures occur before 40 k is reached , it just points to a probability that its higher. Until I see some catalogued evidence of an even spread of IMs failures in hgher mileage engines I will continue to beleive that the IMS failures are not random but caused by external influences such as mileage , oil change interval and driving behaviour . Bearings should fail randomly and the fact its not deemed a servicable part suggests it should in most cases outlive the rest of the engine. A grouping of failures at 30 - 40k miles suggests a special cause failure rather than the normal random causes.

This is a PCM 1.

Have you pressed the two buttons ? This should show you the software version at the top of the screen .

I beleive that the M97 engine is the 3.4 Variant in the boxster S and higher output 2.7 in the standard model that came into production for the 2007 model year. The larger M12 nut configuration IMS bearing and housing was introduced for the 2005 model year vehicles and was also found on later 986 models, this was revised again for the 2008 model year. From the parts listing it looks like Porsche went back to a double row bearing for 2008 from the single row bearings used previously

Same as the last post. If the car is a MY 2000 it probably has the PCM 1 .

When i purchased a new clutch for my 987S I bought a Sachs item from the local retailer. The genuine Porsche part is also made by sachs and identical in every way apart from the price which was nearly double ! Sachs also have a performance division that offer hand made performance clutches with uprated friction material , release bearings and cover plates. From memory the performance item was only marginally more than the original porsche part. On the 987S the flywheels are made by LuK , though I beleive they are tied into agreements with porsche to only sell the porsche stamped and priced item. This may now have changed as I bought my Dual Mass Flywheel about 2 years ago when the 987 gen 1 was the current model.
