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.
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,
I have water on the passenger (right) side floor board of my 2001 996 base coupe. Here are the signs and symptoms, and hopefully relevant info: the water seems to drip from the AC vent. The car hasn't been out in the rain or through a car wash since I dried it out thoroughly. Drove it for about an hour yesterday with the AC on, and the passenger side is soaked. When parked, a healthy amount of condensate came out by the left rear wheel (that's the driver's side, opposite the side where the floorboard is wet), bit nowhere else.
Based on the great info on this site, I checked all four drains under the front cowl. All four were unobstructed and dry as a bone, but there a couple of small leaves in two of them so I cleaned them out. My car has the little clear window over the VIN and the slotted drain grommets, so it looks like the TSB has been applied. I also removed the cover panel on inside of the passenger side rear wheel well. I couldn't positively ID a drain. The area was relatively clean - a little dusty, but no discernible mud, etc. Also very dry. I took out both rear speakers and felt around from the inside of the car all the way down to the bottom of the wheel wells. I suppose that tip only works on the cabriolet...it was clean and dry inside both and there was no drain line .
I ran the car with cowl under the hood/bonnet off and the AC on. The AC lines get cold and water condenses on them (both under the bonnet and running along underneath the car on the passenger side), but it doesn't leak or drip excessively. While it was running, I looked underneath, and saw water dripping from the plastic skid panels under the center of the car up forward. It didn't do that yesterday. I can't imagine that pulling out a couple of dry leaves from the drains under the bonnet made a difference...could it have?
I'm pretty sure that the issue is condensation from the AC system, since it's getting wet from no other source (and it's clear water, not coolant). It would help me to know: where is AC condensation water SUPPOSED to come out under the car when everything's working properly - front, rear, both? Is there a drain hose from the AC condenser that I can access somewhere up front other than as mentioned? I apologize if this is covered clearly somewhere else. I'm just kinda flummoxed...what am I missing?
Thanks very much for any guidance (even a link to some obvious other posting I should have found already)!
