I have been restoring a 2005 Boxster that suffered water ingress to the cabin. Most of the roof and rear module stuff is now fixed. However, there were a few persistent convertible top DMLs in the Gateway module that I was trying to clear with my PIWIS II tool. I think I managed to erase the programming of the Gateway instead of the fault codes. Now the instrument cluster is dead, the spoiler is always extended and the cooling fans are running at full speed whenever the ignition is on. I tried to reprogram the Gateway using either the Automatic or Manual programming modes, but both give the following error: No relevant programming rules found. Cause: Part Number of GATEWAY control module is not available in programming rules. Does anyone know how to fix this?
Thanks Loren. Further updates for the benefit of others with this issue: I discovered that the convertible roof relays above the drivers footwell fuse box were clicking, but not actually working. The relays did not switch any current when I applied voltage to them. I replaced both and now have an operational roof motor and lifting decklid cover. I guess it has not moved in many years as the first thing that happened when the roof started moving was the 2 plastic ball joints broke immediately. I also found 2 loose triangular plastic trim covers trapped in the roof mechanism, one on each side. I have ordered $30 OEM replacements from ebay. I am quite sure I will find further issues when the ball joints are replaced, and I need to find where the loose trim covers need to be replaced to. The double clunking noise has stopped, so I can now leave the battery connected all the time.
Updates after some investigation: Fuse A3 was blown, now the rear spoiler extends and retracts correctly and Terminal 30 voltage supply motors error code is gone. However, still some issues: When pressing the roof close button, I get a click from the relay, but nothing else. The roof open button does nothing, no relay clicks. I switched around all the similar relays in the holder but the fault did not move. Whilst I was under the dashboard switching relays around, the convertible deck cover did open then close again, but I could not replicate that again, I do not know which relay I pulled that caused that to happen. (A relay diagram would be very useful.) I am still getting the 2 clunk clunk noises in the trunk area about every 30 secs.
Any thoughts or guidance would be appreciated. I bought a project 2005 987 Boxster S Tiptronic that had been parked up for 6 months and a reasonable amount of rain water got into the passenger compartment. The rear control module under the drivers seat was corroded and toast, so I replaced it. I also installed a new battery as the previous battery did not hold a good charge. I now have functional rear lights, but the spoiler is stuck in a slightly raised position and the roof does not operate at all. If the battery is connected and the car is shut off with no key in it, there is a double clunking noise from the trunk area every 30 seconds or so. The parking brake light comes on when I apply the brake. The soft top roof switch does not do anything. The manual spoiler switch does not do anything. When I try to operate the same units from the Durametric 'activations' page, I get nothing. (Also, the fuel gauge shows totally empty and Durametric reports an issue with Fuel Level Sender, so I have ordered a used one off ebay.) I scanned for codes using Durametric and got the following 8004 error, which I have googled extensively with no good solution found: Rear Body Module Current Fault Codes 8004: Terminal 30 voltage supply motors Right Door Module Current Fault Codes C121: Communication rear control unit (comfort) 8701: Door lock module 8705: Door lock signal implausible Instrument cluster - 9x7 Current Fault Codes 9112: Fuel level sender Porsche Stability Management - PSM Current Fault Codes 4444: Steering-angle sensor not initialized
It won't help the earlier posters, but this sounds like symptoms of water ingress into the Rear Control Module located under the drivers seat. I had precisely the same symptoms, a soaking wet carpet and the RCM was badly corroded. I replaced it and it fixed most of them immediately. A few more issues to resolve yet.
SpawnyWhippet replied to Paul Grainger's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)This is very useful when you want to use a lift with the car, or to move it on its own wheels with the transmission removed. It basically replaces the function of the transmission mounts that support the forward end of the engine. Its hard to do that when using a trolley jack or jack stand.
Perhaps you have a different seat base, but in my car, no matter where the seat was positioned, there was a maximum of only 50mm of space between the seat and the side panel of the car, so any tool I tried to fit in would not make it with the angle of attack.
My 2009 997.2 trunk switch trim is held in with 5mm allen bolts. The rear screw cannot be accessed at all without removing the drivers seat. You only need to loosen them a couple of turns then pop the trim piece upwards with a plastic pry tool to release the clips. It could be possible without seat removal, but you would need a L shaped allen wrench with a shank of 50 - 70mm.
The root cause of mine was the brake light switch. It took a long time to identify this as I got 2 bad new replacement switches. The 3rd replacement switch fixed the issue. I also ended up replacing the switch on the ABS unit and a few other parts before identifying it to be a succession of bad switches.
I have been running my car with one spray of DeoxIT D5 for 8 months, no recurrence of the airbag light. At this rate, one can of cleaner will last the lifetime of the car.
I rebooted yet again and this time success. No changes made, no configuration different, same cable and same car. Now I can access 996 through OBD. Maybe some kind of glitch. I noticed that my software was actually 17.5, not 18.1.
I have a PIWIS II system running v17.500. It connects and diagnoses to anything later than 2005, eg 997, 987 etc, but it will not allow me to run diagnostics on 996 cars. I can select Porsche 996 under the Diagnostics menu, but when I start to interrogate the car, I get presented with a menu of cars that are all 997 or newer. I tried selecting 997, but the diagnostics fail. I can still access 996 OBD with my Durametric pro, but I would like to be able to use PIWIS on 996 instead. Anybody have any suggestions on how to fix that? Also, is there a way to update maps, program keys for '09 and newer cars outside the dealer network using this?
Thanks for that, but I think the part I need is the rubber part is in the rear of the transmission between the 2 pieces numbered '3'. Is that replaceable? I am getting jerky gear shifts and rough idling. I already replaced the engine mounts which made a massive difference, but after driving a 20k mile version of the same car yesterday, I noticed my car has much rougher idle and gear shift.
