  1. youtube has some great videos how to do this including removing the front seats.
  2. I ended up just getting it to pass the E Test and that was good enough for me. I had both fuel pumps and a fuel pressure sensor replaced. Crazy the PSI these things operate at! I also recently noticed a small leak near where I had the flex pipe repaired - I think that's also throwing off some errors. Ill plug it into my Durametric in the next couple days to see if that eliminated the 12A2 and let you know. Once it passed the ETest I never looked back since it has run well for ages. It's so old now Im only keeping it running at this point.
  3. I'm at a loss what to even try next ... ANY suggestions appreciated !! Compression 240-245 in all cylinders except for #2 which is 200. I think these are good numbers for a 10 year old engine. When the lifters were replaced so were a pile of gaskets, seals and hoses. Very very minor scratches in multiple cylinders. This doesn't look related to scoring, so common in these questionably designed 4.8l engines. Rough idle, knocking and heavy smoking at low RPM acceleration – often car struggles after coasting in gear 5 or 6 then having to accelerate. Shreds oil
  4. Did you ever figure this one out? I also have a 2008 Cayenne V6 running OK but codes for P12A2. It's not running perfectly - every once in a while at idle the RPM drops about 150-200 and its very slightly rough for about a second. This may be when the CEL gets triggered. It only takes a couple minutes of city driving to post it as pending then pops up as a CEL after about 20km - always at idle. I have to pass Ontario's check engine light test. The car has been trouble free for 9 years (other than being on its 3rd drive shaft) knock on wood ;) Funny how my 2008 V8 burns more oil tha
  5. Did you get it fixed? Who did you take it to for the repair? I've been living with the same problem for months now. My local independent told me they don't have the tool required to line up the camshaft after the repair so they can't do it. Does anyone know of a good independent Porche mechanic in the Toronto, Mississauga, Oakville or Burlington area that could do this kind of repair?
  6. Any update? I've started down the same path of repairs. I've had the rough idle problem for about a month and it seemed just an annoyance until last week when after a long highway drive I had to drive for an hour in stop and go traffic. The car started to feel like it was going to explode! So bad I had it taken by flatbed to my local shop. They replaced the plugs and coil packs and tried to clean the solenoid valve but the smooth idle only lasted about a kilometer. I'm going to have the solenoid valve replaced this week.
  7. I have exact same problem on an 08 S. Anything above 800 RPM and its so smooth. Below 800 RPM rough idle. I dont have all the codes observed but think it's the "valve lifter solenoid bank 1" + misfires. I'm dreading taking it to the dealer but I'm not sure my Non dealer mechanic will be able to do better. Hoping you found the cause of this before I pay the dealer a fortune to try and figure out what must be a common issue.
