I bought a used unit off ebay and re-coded to my particular options with Piwis.

Long story short, my local dealer accidentally coded the incorrect VIN into all the modules in my Macan, including DME and TCM. Supposedly this is not possible but they did it and I have cast iron proof. (I now have 2 DME's with the same incorrect VIN and scanner screenshots showing the correct VIN in my vehicle). They refuse point blank to rectify this and state it is not possible to change the VIN, they can only to replace every module in my vehicle at my expense. (This is not viable, the car would be mechanically totaled by the bill.) Better Business Bureau and Bureau of Automotive Repairs were toothless and the dealer just ignored them. So, onto solutions, what is my most cost effective way to get the correct VIN coded back to my car? I have PIWIS 2 and PIWIS 3 clones, but they are only able to change the VIN on some of the modules. I am unable to change the VIN on the DME, TCM, PCM, Front Camera, Airbag, Amplifier, Steering Wheel electronics and a couple of others. Are there companies that can reprogram these on the bench, or via OBD? Is there a dealer or R&D engineering process for recoding the VIN on these modules that I could access somehow? This needs to be corrected, as the vehicle will never be able to pass smog in the future as the VIN in the car does not match the VIN on the registration. It also appears to be a stolen vehicle now if anyone checks.

Did you find the cause of the error B10151B Battery main switching switch unit, limit value exceeded? I saw your other post on the Macan forum and have a similar issue. My project 2016 Macan S was rebuilt using the wiring harness from a wrecked 2017 Macan S. I already replaced the battery negative cable with no change, and the fusible link seems to be OK on the positive terminal. I can start the car just fine, but the airbag light will not turn off due to this error code.

Hi, could you please help with this CDR 220 radio code: Typ: CDR220 Model: BE 4462 Serial: X5036570 Thanks in advance!

I managed to complete the job, but it was not easy. DIY to replace Cayenne turbo without dropping engine - Rennlist - Porsche Discussion Forums RENNLIST.COM DIY Submission Forum - DIY to replace Cayenne turbo without dropping engine - I am writing this DIY as I couldn’t find anywhere that described how to DIY a left turbo replacement on a 2005 Porsche Cayenne Turbo, and all the mechanics I spoke to said the drivetrain must be dropped out the car to do...

I found faults in the relays above the fuse box. They clicked when activated but passed no current. Replaced them and the roof and spoiler started working again. Also one of the fuses was bad. I reprogrammed the rear control module to match the options in my car using Durametric.

Nothing heard from this forum, I'll concentrate my efforts elsewhere.

I'm guessing that silence is a "no". As I couldn't fix it either, I picked up a replacement gateway from ebay for $30. Will fit it on arrival.

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 have ordered $30 OEM replacements from ebay. I also found 2 loose triangular plastic trim covers trapped in the roof mechanism, one on each side. The double clunking noise has stopped, so I can now leave the battery connected all the time. So now, after all those fixes, the roof went up and down correctly 2 or 3 times, then I get an error on the dashboard about 'Convertible Top Module Error' and the switch no longer works, neither does the Activation command from Durametric. Where would I locate the Convertible Top Module? Also Fuse D2 (15A) goes to ground. It says it is the blower motor for engine compartment (997) in the fuse diagram. Any suggestions on whether this fuse should be 12V, and what it actually powers on a 2005 Boxster S 987.1?

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

I have the same issue, what was the resolution for you? I already replaced the Rear Control Module.

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.
