I am absolutely going nuts....I am getting ready to push my pig off the cliff. My 04 s has been pretty good but lately I have been bleeding money with it. Recently I had a PSM workshop message had a bad battery( replaced both for good measures) and a bad alternator. Replaced them. Then I had oil pressure switch go bad, then I started blowing a fuse from a faulty fuel pump. Replaced them. Then I had a cam sensor go bad replaced it. (not all at once but over 6 months)Now I am getting a PSM failure message with the following faults and the car will only turn over but will not start.

P2186 Throttle \peddle sensor\switch voltage correlation

P2170 Throttle\peddle sensor d circuit below limit

P2174 Throttle peddle sensor switch e circuit below limit

P1514 Throttle adjust unit upper limit value exceeded

P2186 terminal use 30 for vehicle electrical control module-upper limit exceeded. Test conditions not complet





Do I put in a new throttle body? What's the P2186 code?

Deep breath. Think of the difference in property tax, payment, depreciation for a new vehicle. Repairs always sting because they're not budgeted.

I do not miss "personal property tax" in VA.

Sorry to hear of your beta problems

Do you think its the pedal sensor or throttle body? I have never seen the P2186 code before?

I did but that thread is unclear if the pedal sensor was actually the issue.

Update... I have been able to get all of the codes go away and psm message but have one left P0112 temp sensor. The cayenne will turn over but will not start. I have replaced the MAFs(both), pedal sensor. i need some thoughts on what to do next...if I don't figure this out soon i am going to let it roll down the hill into the lake.. 'either that or i am going to go into the poor house.....

Update#2

Well I towed my Cayenne to my indie shop and they started by testing the fuel pumps since they just replaced them. They tested fine. Then they did a fuel pressure test and they said it was great (static and something else I can't remember. I thought they said it was at 55?). Then they inspected the coils( version ending 08), plugs and tested current and end spark. All tested fine. Then they did a cylinder pressure test and all tested within specs accept cylinder 5 which was slightly low but within tolerances. The car will turn over but not start. I have them putting in new plugs as it has been a couple of years. They are going to continue diagnosis but already up to $450. Any thoughts? Suggestions...btw the only code that it is throwing is the air temp sensor p0112.

I have to ask...did you verify that the batteries, alternator, etc. were in fact bad before replacing them?

Try this.

Well then... Go ahead and...
