Yesterday, when I returned from a drive of about 30 minutes, I saw the Four Wheel Drive system Faulty message on the display. After about couple of hours, I started the car and the warning showed up again. I took it for a 5 minute drive, turned off, restarted it and the warning showed up again, decided to drive it back home, but it was a bit jerky when it started moving from rest and then gave PSM failure warning and then Lock overloaded warning. Was able to drive it home without any more jerkiness.
I doubt that it is battery related but will have it checked.
One thing I noticed is that the front tires are worn from sides only as the front LCA need to be replaced. Could these cause these warnings? Or is something else going on?
I purchased a 1999 Porsche Boxster 986 about a year ago and I'm having a few problems with the electrical accessories. The top worked fine when I bought it, but now it won't work sometimes. The radio also turns on, then immediately off at startup, and it won' turn back on until a few minutes later either by itself, when I use turn signals, power windows, brake, or even just by itself. After the car is "warmed up", then it will stay on. Other things won't work right or not at all, such as the alarms for, ignition, door open, light switches, etc. The fuses are all fine, and I know the battery had been replaced right before I purchased it. I haven't checked the relay for the top, but I am about to do that now. I feel like there could be a single problem creating all these issues. Any help would be greatly helpful and appreciated!
Greetings and thank you for the informative site.
I am a new owner of a 2009 Cayenne base model with dead Horn. I’ve read on the forum of typical failures, including steering wheel wire and two horn units. So far I’ve confirmed the fuse is ok.
Before removing wheel arch covers to test the horns, I wanted to check the relay.
Is the horn relay in the under hood fuse box? If so, which position?
Odd one for the group here:
I have a 2004 Turbo Cab (manual) with X50 that I have owned since early 2010 and put around 30K miles on in that time (Bought with ~20k miles). I recently found a 2004 Turbo Cab (Tiptronic) with ~29,000 miles that was such a good deal that my parents purchased it. I drove the thing recently while visiting and a couple times in constant-radius turns on back roads, the PSM intervened out of nowhere (The first time it happened I actually thought I hit a shift button with my thumb and downshifted mid corner). Anyway, I got it to intervene once more in a pretty benign turn. There certainly wasn't 7 degrees of slip angle and I have to push my own car much harder (read: screw up the corner entry) to get PSM to intervene. I guess my question(s) is/are this: Is there a difference in the PSM software between the Tiptronic cars and Manual?, a malfunction in the Tip?
Very interested to hear the responses. Thanks
I was troubleshooting code P2189, undo some vacuum line to test for leaks ... this is a different issue all together. I mentioned it because I unhooked vacuum lines. I reconnected everything (hoses), I did not start the engine because I was still working on it. My engine was running fine for weeks even with P2189 - not rough like some mentioned!
Two days later, In the morning, I used the car to do errands, I drove for about 10 minutes. At the stop sign, I stepped on the brake, the car won't stop like it used to! It rolled slowly and then stopped. It's like taking a much much longer distant to stop. I did not see anything abnormal on the dashboard except for the CE for the P2189 code! no smell of anything. I continued to drive the car at the normal speed (35 mile/hr) but kept a large distance from the car in front. About 10 minutes later, the brake felt normal like nothing had happened. I drove for another 10 minutes to reach my destination. 2 hours later, jumped in the car to drive home, the brakes felt normal. About 2 minutes the PSM light came on, brakes are still OK. 5 minutes later I pulled into the bank, turned off the engine for couple minutes then restarted the engine, the PSM light is OFF, the brake is normal... I drove home.
Now, where do I start troubleshoot the brakes and the PSM light? I don't have the Durametric tool. Or must I have the Durametric to troubleshoot? can I rent one from someone?
Your help is needed.
Thank you in advance for your assistance.
