Hi all,
My 2004 Cayenne 9PA 3.2 has suddenly developed a fault. It started by saying "four wheel drive error" on the dashboard and shortly after "ABS failure" followed by "PSM" failure. The centre console four wheel drive system switch (behind the gear change) is also not working (LED light not going on if the dial is moved).
I changed the battery with a brand new one, top of the range and went to my local friendly Porsche mechanic who run it through diagnostics, cleared codes and they popped up back again which he then attributed to an electrical fault in one of the cables. As he is a mechanic and does not cover electrics he suggested I find a specialist that covers electrics.
I checked all the fuses and they look ok.
The car drives ok but when started it seems like it is trying to lock the wheels (like when in the past the PSM would engage).
Any help? I have a tester so would not mind checking continuity of ground points etc, but rather than taking the whole thing apart it would be great if any of you has a suggestion - which would be greatly appreciated.
Thanks in advance,
Alex

I'm having a problem and think the brake switch is at fault...but not sure.I have the ABS/PCM lights showing up on the dash.When the headlights are turned off, my brake lights function normally. I don't get the warning lights when the headlight switch is off.
When the headlights are turned on, the brake lights do not turn on and the ABS/PCM warning lights come on.
Would a faulty brake switch be the cause of this or could it be something else?

Both yesterday and today I got both PSM & ABS lights on the dash during a hard acceleration (maybe some wheel spin) in 2nd gear. The lights popped at about 5K and stayed on, but turned off after shutting the car off and restarting. I checked codes in ABS 5.7 via Durametric and got 5525, Incorrect data transfer with DME master control unit.
Any thoughts??

Recently I started my 99 Boxster and noticed that the ABS and Battery Light came on. I had this issue last year when my alternator failed so I hurried home as to make sure I didn't stall on the side of the road. I made it home and checked my voltage readings on the battery. With the engine off the battery read 12.5 and with the engine on the reading was 14.44. When I went to start the engine to check voltage, the lights were not on. Drove couple of days and the two lights came back on, but when I shut the engine off and restarted, the lights went away.
Anyone have experience with this type of problem? Could this issue be caused by thin brake pads setting off the brake wear sensor?
Any advice/help is appreciated.
Thanks
Andy
