  1. I have a 2003 TT and recently the PSM traction control light will flash briefly (maybe 3-5 seconds) and the engine drops power, no other indicators, no check engine light, nothing....light stops flashing and engine power comes back. If i turn the PSM off, i have no problems, but with ~4,000 rpm shift points in auto and Borla exhausts, the neighbors are getting tired of me. I was by my mechanic's shop the other day on an unrelated issue and he hooked up the Porsche computer and there were no stored faults in the PSM Management. Anyone seen this? Any ideas?
  2. 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 i
  3. Long story short, one day noticed water in the drivers footwell, found a leak on the door to body wire harness. Dried car out. Car was 100% before this, seemed to be OK even when wet. 2 Weeks later, car started getting random faults on the MFI (Brake, ABS, PSM, etc). Would clear, then come, then clear. Battery is about 7 months old (replaced when I first got these errors) Ton of errors in durametric, then one day would not start or move out of if it did start. Peeled carpet back. Found 3 wires. 1 Crimped, 2 soldered. 1 of the soldered was gone, so cut that out, butt sol
  4. 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 p
  5. 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 d
  6. 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. A
  7. Does anyone know where this is? I was able to catch a code today when my PSM light came on, and I went into limp mode at highway speeds. I pinout would be nice, so I can trace the can-bus wiring. DTC 1314 - DME Googling around, sounds like loss of connectivity to the DME, all other modules have not logged any issues talking to the DME. This is the last of symptoms a massive wire harness failure I had late last year, after repair this is the 3rd time this has popped up. DME has no codes, may be a red herring but the AWS advanced weigh
  8. Hello guys, Ii rented an innova to clear the codes, i just had too many old one, but weirdly a PSM failure i had for a while, but came back :-(. While it was out i was able to press the PSM button off/on and it lit up and off and appeared everything worked. Also the sports button and that struss type button could be turned on / off. Now all are out :-( I wonder where i can find out what is messed up. I went under the drivers seat, i will attach pics soon, and will like to buy those connectors with cables to re-do all that cabling down there, it is ugly. Idea
  9. hello i got new speed sensors, maf but a second hand abs hydraulic unit... this codes are from durametric 5281 Version coding 4400 Transverse accleration sensor 4480 Booster pump 22 CAN: rear right wheel rpm from PSM implausible 25 CAN: front left wheel rpm from PSM implausible
  10. 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?? 1999 Carrera 4, 124,000 miles.
  11. PSM light is showing on very mild/slow turns, both in right and left directions. It causes a weird driving condition when its flickering, loss of power, feels like sputtering. All seems fine if if I turn PSM off. Any suggestions? Is this a bad sensor(s)? If so, where is it? I had a a P2189 Lean Bank 2 at Idle, and I replaced the MAF, checked the fuel pumps (all good) and (mechanic) smoked the system. Found leak when smoked cold at a variable timing cam gasket (replaced). No leak now except tiny amount from left turbo. That code seems gone now and nothing else seems to be relev
  12. Hi, My first post to the forum, hopefully someone can help, I had a problem with the air con not blowing cold, my first port of call was to check the fuses. all ok but when I started the car again I had PSM failure and PASM failure messages on the dash. Car hadn't moved. I have run Durametrics and tried clearing the faults. I now have the following fault codes. PSM fault codes 5400: Fault sport mode 4444: Steering angle sensor not initialised Air conditioning 8023: Outside air/recirc. air flap motor I was wondering if anyone has come across this and if there is a quick fi
  13. Running into some trouble trying to bleed my rear brakes and I've isolated the issue, but don't know how to resolve it. Hoping someone here more familiar with the PSM module might be able to help. Issue: I'm using a Motive bleeder and have good flow into the "H" (rear) input port of the ABS block, but I have no flow from either the HL (rear left) or HR (rear right) output ports of the ABS block. I know the PSM system doesn't have a mechanical proportioning valve, but could the system have electronically isolated the rear circuit? If so, any idea how I might reset it? That could
  14. Hello All, my PSM is back on my '04 S. I cleared the codes, disconnected the negative battery cable and PSM comes back after about a day or so. No CEL on only PSM. Error codes P2186 Throttle/Pedal Pos. Sensor/Switch D/E voltage correlation-implausible signal, test conditions are not complete fault is currently active and is not causing a DTC light.

  15. Okay...here it goes...The last time it went into PSM it cost me over $3500 and that's after I replaced several parts my self (both MAF, Throttle pedal assembly, cleaned throttle body, cam sensor bank 1 replaced) ..Anyways...I made it home and plugged it in and have the following: Durametric Codes P0112 (Intake Air Temp Sensor 1) P0343 (Camshaft Position Sensor A bank 1) P2186 (Throttle/ Pedal Pos Sensor switch D/E P2174 Throttle/Pedal Position Sensor /switch E P1538 Throttle Adjust unit lower mechanical stop relearning implasusible P2169 Throttle/Pedal Position Sensor switch D P1535 T
  16. Well, while driving home I got the PSM workshop message. After a couple of minutes of driving, when coming to a stop, it would go very slowly and then finally kick in. Once home, hooked up the durametric.

  17. Just got my tires replaced and the PSM kicks in more often than it did before. Sometimes on mildly enthusiastic turns. I suspect it may be what Discount Tire may have set the tire pressure at. Can this be the issue? I'm assuming Discount may have put equal tire pressure on all four.
  18. Hi I have a question please I wonder if someone can answer? I have a 2004/05 4.5V8 Twin Turbo, Tiptronic. When driving normally, leaving the car in normal D (Drive) the car is quick to shift gears between 2000 and 3000rpm, going up the gears as quickly as it can, often leaving me in too high a gear and being very sluggish. I've recently noticed, if I turn off the PSM button, the car shifts alot later in the revs, between 3500 and 4500 and in doing so, always sits just on the turbo and feels so much more responsive. flick the PSM back on, and the car returns back to its sluggish ways
  19. Hi guys. First time here for me. I have bought the Cayenne s and have som trouble with it. The car was standing out side over night in about -5 Celsius. In the morning when I started the car the PSM default whent upp in the display. I tried to restart the car but it did not disappear. When I was driving the car the gear box did not whant to change any gears. Think it's running on 2 or 3 gear all the time. I live in the northern part of Sweden and there are no porche dealers here. So I took the car to the only guy who has the Porche computer. When we connected the computer it says: tiptro
  20. I've been experiencing ABS/PSM problems ever since replacing worn out rear tires and using a different wheels on my MY02 996 C4S manual. I replaced the rears with exactly the same OEM sized tires, but with different wheels. Prior to tire/wheel replacement I've never experienced any ABS/PSM issues.
