  2. I had the privilege recently to replace starter on my vehicle. Symptom was car was not starting, when attempting, I heard a clicking sound from under the hood (when hood opened, clicking comes from the area under intake manifold, where the starter is). The clicking comes from solenoid trying to engage starter, but the starter motor not turning on. After fuse checking, and making sure battery is good, next step was starter. Given the clicks, and other items being fine (and no other engine errors), my next step was starter replace. Long story short, it was the starter. Replaced my turbo starter with genuine Bosh starter, price $255 shipped from eBay. Porsche PN: 948 604 210 01 Bosh PN: SR0447N Intake seal PN: 948 110 146 01 (will need 😎 Below is a DIY for removing and re installing new starter into the car. If you have done things like coils/plugs replacement, this should be a breeze for you. Even if you have not done more than oil changes, it is not difficult, but takes time. So if you do not feel like spending about $1800 for this at the shop, you can do the job yourself, spend about $250 on the part, plus about 2 days of work (this is worst case, if you have not done any work on your car yet). Take time, be patient, mind all hoses in the way (if you crack and do not know it, you will be back there to replace these, and PD may be tricky, so why not just keep an eye on everything). Torques in pictures, follow the sequence. I recommend you read all of the steps, so you can understand the process before you begin. Then get some beer, turn up your favorite tunes, and go to work. Enjoy and hope this helps others in similar situation
  3. DIY: Manual Radiator Fan Switch w/ an OEM Switch Fan Switch Part List $32 Defroster Switch, Matte Finish (996-613-134-10-A05) $25 Omron MY2K-DC12 Latching Relay $5 ATC Fuse Tap with .250 Male Disconnect $5 2.8MM Female Wire Terminal Various Male & Female Disconnects, Butt Connectors and Heat Shrink Tubing Various Lengths of 16AWG Wire Optional: $23 2-Button Batwing (996-552-335-02) Garage Switch Part List $47 996TT Targa Switch (996-613-119-10-A05) Various Male & Female Disconnects, Butt Connectors and Heat Shrink Tubing Various Lengths of 16AWG Wire Background The 986 is equipped with a left and right radiator fan. These fans have two speeds, high and low. The low speed fans come on whenever the AC is turned on, the high speed fans trigger when the coolant temp hits 215° F or the AC pressure hits a certain level (source Bentley Manual). While you could wire a switch to trigger the low or high fans, you can already trigger the low fans by turning on the AC, which is why this modification focuses on triggering the high fan speed. The point of installing a manual switch is to help cool your 986 before it hits the temperature threshold where the high speed fans would automatically come on. This could include track days where you want extra cooling and do not want to lose horsepower to the AC, or when you are in summer traffic and want to keep the car from heating up. Installing a manual switch should not override the normal operation of the high or low speed fans, it just lets you trigger them manually. If you leave the switch on when the car is turned off, the fans will automatically turn off after a short delay, and the fans will come on the next time the car is started. Preparation Start by disconnecting your battery, and placing a small block over the trunk latch to ensure the trunk does not accidentally close while the battery is disconnected. If you are installing the switch into the batwing trim piece: -Remove the carpeted trim on the driver and passenger side of the lower center console by grabbing the rear of the carpet and pulling out until the clips release, then slide the trim back and out. -Then remove the leather/leatherette trim on either side of the lower center console by grabbing it from the back and pulling out until the clips release, then slide it forward and off. -You can now remove the batwing by pulling on each side of the trim piece. -While not necessary I wanted room to work, so I also removed both cubbies from my lower center console. Remove the upper one first by pulling it out from each side, then the lower cubby is able to removed the same way. Step 1 - Wiring the Relays First you want to identify the high speed fan relays. They are located in the driver’s footwell above the fuse panel. The bottom row that is visible has four 53 relays, looking at the diagram the high speed relays are #20 and #22. Remove both relays. Now take a fuse tap and pliers to bend it to fit Pin 85 on the relay. The fuse taps I purchase required some filing to make them wide enough to over the relay pin. With the fuse tap installed, secure it to the relay. I decided not to use electrical tape because the relays can get quite hot while the car is running and I want to avoid a sticky mess, so I instead opted to secure them with a zip tie which I pulled tight with a pair of pliers. Note that the head of the zip tie is pointing down to make it easier to reinstall next to the other relays. Next take approximately two 6” wires and install two female disconnects on one end of each wire which attaches to the fuse taps, then combine both wires into a single butt connector. On the other side of the butt connect you want a few feet of wire that terminates in a disconnect (male or female depending on how you wire the relay and switch), mine ended with a female disconnect. This is the Pin 85 wire, that will be attached the latching relay later on. Route the wire to the center console, by pushing it up and around the plastic air tube above the driver’s footwell, then into the lower center console. Step 2 - Wiring the Switch and Latching Relay Since I was using the batwing trim piece I started by installing the switch into the batwing. This is tougher than you would think. With the switch in place but not “snapped in” I placed the batwing and switch on the edge of a table with the outside facing up. By using the edge of the table I could rest the batwing on the switch pins but let the batwing hooks which are longer hang off the edge. I think hit the trim piece with my hand until the switch snapped into place. I also placed thin cardboard on the table to avoid it getting scratched by the switch pins. The switch should sit flush with the batwing if installed correctly. The 2.8MM female disconnects are for the relay pins which are smaller than the switch pins, which accept normal female disconnects. To make the batwing removable, I used male and female disconnects. If you decided to do like me, instead of just hardwiring it into the car without any way to disconnect it, you would end up with four wires that need to be hooked up: Relay Pin 85, 12V Switched Power, Ground, Illumination Power. It is rather hard to describe the wiring in text so please review the diagram below. Switch Pin 1 - Relay Pin 14 Switch Pin 2 - Relay Pin 12 Switch Pin 3 - Illumination Power from dash Defroster Switch Pin 3 Switch Pin 4 - 12V Switched Power from Phone Connector Switch Pin 5 - Relay Pin 5 Relay Pin 9, 10, 11, 13 - Ground (I used the Phone Connector Ground) Relay Pin 11 - Pin 85 Wire Relay Pin 1 & 4 are not used Notes: -The Phone Connector 12V Switched power is Green/Black -The Phone Connector Ground is Brown -I wrapped the latching relay in some electrical tape to help “cushion” it but that probably isn’t necessary. -For the 4 Relays Pins that need to be grounded, I connected the wires using butt connectors. -The illumination power must come from the dash Defroster Switch Pin 3, this switch is wired differently than the others, and using a different source will cause the switch to always be on. Step 2.5 - Illumination Wiring I had previously tapped into the cigarette lighter for illumination power and ground, and the original plan was to use the same wiring. In most of the pictures in this guide you can see that the two switches share a wire, which was supposed to be the illumination wire. However, the defroster switch uses a different signal for illumination than every other other switch in the car. So you need to tap into the defroster switch in the dash for the illumination to work properly. Take a butter knife and insert it into the bottom of the switch panel, then carefully pry the trim piece out, it should unsnap and come free. The wiring hareness doesn't give you much room to work with, but you only need to remove the plug from the defroster switch. I used a flathead screwdriver to get it started, then carefully removed it the rest of the way, being careful not to damage my dash. As you can see, I chose to use another fuse tap on Pin 3 of the dash Defroster Switch. I secured it with a zip tie, and then ran a wire behind the center console to the lower center console. I removed the radio to route the wire, it may be possible without this step, but it would be difficult. Removing the radio requires inserting radio keys into the lower left and right slots. Step 3 - Installing the Batwing & Switch Slide the latching relay and wiring through the batwing opening. You may not be able to fit the latching relay through the batwing opening, so be prepared to disconnect the relay from the switch and plug it back in. With the wiring in place, connect the four loose wires: the Pin 85 wire that runs to the relays, the illumination power coming from the defroster switch, and the phone connector power and ground. Test the fan switch by reconnecting the battery and turning your key to the first position (power on), the latching relay requires 12V to operate, so it won’t work with the car off or the battery disconnected. The left side of the switch should trigger the high speed fans, and the amber LED in the switch should illuminate, the right side of the switch will stop the fans. Snap the batwing into place, and reinstall the lower center console trim in the reverse order. The Easy Way Follow Step 1 to tap the relays, then connect them to a simple on/off switch with the other end grounded to the phone connector or another ground point. You can stick the switch on the bracket under the steering wheel. I originally installed a simple switch this way and it worked fine, but I wanted a more clean and permanent installation. My last step is to install a 2.5" silver '986" decal on the batwing. Thank you to particlewave for his help figuring out the wiring on 986forum, and RennTech member Sandy that created the latching relay diagram I modified. You can also find this DIY on my personal website: blueboxster.com Note on the Engine Compartment Fan: You could also use this same switch to ground the engine compartment fan, you would just spice it in to the Pin 85 wire. I chose not to bother running a wire from the engine compartment fan relay in the rear trunk, because after using my durametric to review my oil, coolant and engine compartment temperatures and manually trigger the engine compartment fan, the engine compartment temperature does not appear to have any significant affect on the oil or coolant temperatures. Garage Switch Because I installed my fan switch in a 2-button batwing, I needed another switch to avoid using a blank (I have been on a quest to eliminate blank switches from my 986 since I got it). I decided to hardwire my garage door opener. I opened my garage door opener and used a wire to determine which two contacts needed to be connected to trigger the opener. I then soldered two wires to the two contacts, and drilled a hole in the side of the opener for the wires. You can test the opener by touching the two wires together to see if the garage door opens/ closes. Next I wired one wire to Pin 4, and the other wire to Pins 1 & 2. This allows both sides of the switch to open the garage door. If you have two garage doors you could wire one side of the switch to open one or the other. Pin 3 is the Illumination Power, and Pin 5 is the Illumination Ground. I installed disconnects on the two illumination wires and on the three garage switch wires to make the batwing removable, and to make changing the battery in my garage door opener easier.

  5. I found this and it is a great info on how one can remove door panel on the Panamera. This vid shows details on what to watch out for, what to do. If you find yourself wanting to replace any of the switches on the doors, get behind he panel, this vid shows it all. Enjoy.
  6. The cigar lighter and footwell accessory sockets in the Gen 2 are always live (I think this is also the case with Gen 1). This is great when using a battery conditioner (e.g. CTEK) as it means this can be connected via the cigar lighter. NB - The cigar socket is protected by 15A fuse whereas accessory sockets by 7.5A - You must always use the cigar socket for big loads (e.g. tyre compressor) and for charging. However, I am not sure how many others have the issue of having several accessories plugged into the accessory socket - in my case, a charging adaptor for phone; a Road Angel and a dash cam. Whilst all are in standby when not in use, I do not unplug them as it's a bind to unplug/plug in the blessed multi-way socket I use for all these adaptors; it also means the wiring, normally neatly concealed has a habit of coming out of its hiding places. What I do find is that the combined drain of these various devices, albeit in standby, contributes to the draining of the battery when left for any period of time. In an ideal world, the accessory socket(s) would be switched (ie turned on with ignition) and off when the ignition is off. Further, it would be helpful if the socket could then be turned on permanently should the need arise. I considered a couple of options. One could run a switched live from the fuse box situated in the drivers footwell (from fuse row C) and use a SPDT switch to select between this and permanent 12V supply, wiring this to the accessory outlet. In the end I elected to use a relay to switch the existing 12V supply and avoid changing the loading on any of the existing fused circuits, The relay is activated from a tap taken from an existing switched (Terminal 15) wire from behind the dash - I used the supply to the switch module for PASM, spoiler etc. as this is fairly straightforward to access. Given this is only used to activate the relay, the additional load is no more than around 120mA (relay coil impedance about 100 ohms). This is the circuit diagram. PLEASE NOTE that you should check any components you use as they may differ. I used a micro relay with a built in flyback protection diode - if you use a similar relay, these must be connected the correct way round. I also used an illuminated switch so again, ensure the pins are connected correctly for the LED to illuminate when switch is on. Relay: Pin 30 - Permanent 12V Pin 87 - Switched 12V Pin 86 - Coil+ Pin 85 - Coil- Switch Pin 1 - Permanent 12V Pin 2 - Accessory Pin 3 - LED Ground These are the installation steps I followed. 1. Remove the accessory socket panel from passenger footwell. My car is a convertible so its a bit different to coupe. On the convertible the screw is hidden behind the vaned plasix insert which you have to unclip first. Undo the screw and you can then unplug the accessory socket from the cable harness. 2. I drilled and filed out a 20mm hole ready to accept a toggle switch. 3. To get access to the cable harness for the PASM, Spolier, Sport Mode switch module, you have to remove the passenger and driver side trim panels. On the passenger side, remove 2 torx 20 screws. On the drivers side there is a little carpeted piece which is unscrewed first (the torx 25 screw is hidden in the carpet trim so poke around with finger to find it. Once this piece is removed, the trim can be undone (2 torx 20 screws). The side panel trims can now be removed by pulling/pushing forward. These side panel trims are a fiddle to remove as the front edges are retained by clips. Be gentle and patient when removing these. 4. Once removed the trims you have access to the clips that retain the switch module. 5. Depress these clips and the module can be withdrawn. There is also a little clip on the top of the switch module which has to be pushed down a bit to fully remove the module. You now have access to the plug to the switch module and can unplug it. 6. I next turned my attention to the relay. I fashioned a little bracket from a bit of bendy metal strip I had laying around. The relay is secured using a cable tie. I also put a bit of rubber strip on the bracket just to avoid squeeks etc. 7. My chosen position for the relay. I drilled a small hole in the plastic cage and secured using a self tapping screw. Note the cable tie securing the relay to the bracket. There are other options for installing the relay. Make sure your chosen location does not get in the way of the side panel or other bits. 7. 8. The next step is where we start to do more invasive surgery. As a precaution I removed the fuses to the circuits I was doing surgery on. Fuse 8 on row A feeds the accessory socket and Fuse 8 on Row C feeds the button module. The switched (Term 15) supply I am using is on pin 3 of the button module and is supplied via Red/Grey wire. Be really careful here as there are also Grey/Red wires. You need the RED/GREY on PIN 3. I removed the red case bit of the plug (cut the little cable tie) in order to make life a bit easier. I cut the RED/GREY and tapped the wire (using a bullet connector) adding a tap wire (yellow in pictures). I then put the plug back in the casing and re secured using a new cable tie. I looped the yellow wire through the cable tie to give a bit of strain relieve. 9. Next I cut off the plug to the accessory socket and attached female bullet connectors to the ends. Be careful here as the loom cable is not very long and you wil need to get access to the cut ends to crimp on the female bullet receptacles. The RED/BLACK cable is permanent live. 10. I now fashioned a wiring loom to connect everything up and installed this in place. I removed the relay to make connecting it up easier (which is why relay is dangling in footwell in one of the pictures). 11. Now it is a case of putting everything back together. Put the side panel trims back in first. Again, can be a bit of a fiddle to get them lined up, but do not force anything, when they are lined up right they will slide in and clip in place. Secure them using the torx screws. Put in the little carpeted piece on drivers side. Put back the accessory socket panel. Be careful regarding placement of cables. On Cabrio, be careful not to end up with cables going into the air duct move them to the right where the accessory socket and its plug go. Do not be rough, everything should go into place without force. Dont forget to clip in the vaned insert (Cabrio). 12. Job Done. When toggle switch is in the Off position, the accessories are powered when ignition is on. Can override this by flipping switch to on position.
