how did you find the leak?
just to follow up, I found a used module for a really good price on ebay ($35), ordered and received 2 days later. I changed it this week end and it was a module problem, everything work now!
Thanks for your feedback. I will maybe just buy one and try!
Well, I check the AOS valve and it looks like new. I just cleaned the old oil build up but it will not change anything. That was a small project, I will look at vacuum leak this week end.
Hi angusc, Did you figure out if it is your module? I have the same issue, 2 reds on both sides front and rear, all sensor clicks, no fault on durametric. I removed the module and everything look ok inside (no burn mark....) I am not sure if I try to replace the module
I look at the smoke test, i think i will try that. I need to dig on the leaking possibility, not easy during the week because daily car and when you start you never know when you will finish... I will check the AOS valve too. Spark plugs and coils, hard to believe because ii was like that before, and I replaced everything with new parts and noting changed so... I will proceed next step by looking for leak and do a smoke test at the end of the week and hopefully i will be lucky....:)
I agree :)
thanks for the feed back. I will start to look at the vacuum leak, but not easy without a smoke test equipment. I changed all coils and spark plugs a month ago. About the old one, I did not really check, because I was thinking my problem was coming from the spark plugs/coils (misfire codes). The cat issue doesn't excite me... but I have bank 1 and bank 2, what is the chance to have 2 cat dead in the same time.... I am thinking maybe try to change the O2 sensors, but $200 to $300, I would like to be a little more sure it can be the problem before i change them.
Thank you for your feedback. I will look at this post. hopefully it will help. I already looked at a lot of post but nothing helped me yet...
skalex posted a topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Hi all, I have a cayenne turbo 2005, 140 000 miles now, it’s my daily. It’s a little rough when idling, but fine when driving (all power, everything ok). I also have the issue when I am driving and stop to a red light, the car idle a little lower before coming back at normal idling (from what I understood it is maybe the engine hydraulic mount). What I change in the last 3 months: - spark plugs (I had some random multiple misfire (P0300) and some on some cylinders (P302, P304…) - spark coils (due to misfire) - driver side gas pump (died and had me stuck on a parking lot) - valve cover gaskets (leak) - upper engine mounting arm (needed to be replace) - cleaning of throttle body - cleaning of both MAF I still have rough idle…. sometime I have an engine light on the dash, 3 or 4 time, once a month, and I have 02 sensor error. Can be reset with duramteric or reset by itself too. So I check with my durametric again yesterday and this is what I have: -P0431 catalyst system efficiency below (bank 2) -P0300 random multiple cylinder misfire -P0302 cylinder 2 misfire -P0304 cylinder 4 misfire -P0308 cylinder 8 misfire -P0421 catalyst system efficiency below (bank 1) I don’t know where to start to look now. I googled it and did not find anything. If someone has an idea I am open to any suggestion! Thank you
