PCM unit restarting every 2-3 minutes - Rennlist - Porsche Discussion Forums RENNLIST.COM Cayenne 955-957 2003-2010 - PCM unit restarting every 2-3 minutes - I just had my Cayenne detailed (same guy I�ve been using for years and he�s very fastidious) and the PCM unit is now shutting down and immediately restarting from the Porsche Logo/white screen every two or three minutes. I�m pretty certain he didn�t...
I can’t help you with a dealer. I would check the fuel pump fuse as it might be an easy fix.
Yeah that small leak might be a weakening gas cap seal.
Anyone Install a Remote Starter on their 958.1? - Rennlist - Porsche Discussion Forums RENNLIST.COM Cayenne 958 - 2011-2018 - Anyone Install a Remote Starter on their 958.1? - I just brought home a new-to-me, CPO'd 2012 Cayenne S as my winter DD. The only way I got my wife comfortable with me buying what is now my 3rd Porsche was by promising that her '14 Audi Q7 would always be parked inside in Winter next to my...
Congrats on the cayenne. The TC drain / fill bolts when new come with thread sealant / lock. Getting new plugs is cheap. Get new brake pad sensors when replacing brake pads.
Great post Russ! This is next to do on my list.
I installed a new gas cap, so far no more P0455 code.
I installed a new map sensor and the car is now code free with the exception of the evap large leak code. I put some gummi fledge on the rubber seal of the gas cap. Going to order a new cap tomorrow. As for the subtle vibration at 1800 RPM I have been driving the car occasionally relatively hard and that seams to be smoothing out the vibration. Maybe some of the residual carbon was stuck and now freeing up.... only a guess because I have no codes and it is getting better.
I have been researching these codes a bit. The evap leak might be a bad gas cap seal. The map error might be a bad map sensor. The V8s do not have MAFs. MAP sensors are relatively cheap for the Bosch OEM part. The cam error I am not sure of yet. Maybe sensor or solenoid. I am going to measure the map sensor and since it is cheap enough I ordered a Bosch map sensor. I will get a new gas cap seal or gas cap. I cleared the codes and will see if they come back after the parts replacement are installed.
Does anyone have any thoughts on why after removing and reinstalling the intake manifold I am getting a check engine light and codes P0107 and P2100? I believe the CEL is due to the 3rd code in the attached picture for large leak detected. Maybe my gas cap is in need of replacement. I also cleaned carbon off of the valves and replaced the coolant vent line under the intake manifold. After performing this work I noticed these codes and at 1800 rpm the engine has a new vibration when the car is in park. It’s almost like a semi fowled plug however I never went near the plugs.
Based on your original post I would have said order an oil pressure sensor and check your coils.
^ 100% agree. Why throw parts at the car without first checking the codes? Sent from my iPhone using Tapatalk
Well don’t take my non-explicit response wrong but since their service is subscription based and copyright I wont repeat their process however it clearly tells you how to do this job. Their pricing is also very reasonable if you buy the alldata diy version specifically for your year make and model. I think I paid approximately $40 for 5 years of access... HTH
So I looked on alldata and it does have a procedure for replacing the oil level sensor.
Sorry I have been busy. Let me check if all data has a procedure and if so then you might want to consider buying it.
