PSM Failure warning after batter change
#17
I had a similar situation
I replaced my battery and my heated seats stopped working and also the headlight washers on my 2005 997. At first I thought I just had the heated seats fail on me. I bought it to the dealer and even though I had extended warranty they wanted to charge me. I found someone with the same problem on another forum and they said that a PIWIS reset fixed it for them. So I went and told my dealer and they fixed it under warranty too. Pissed my off though that they did not want to fix it until I told them what the repair was. crappy service manager at the time but luckily now she's gone.

its because the steering angle sensor has to reset itself. turn the steering wheel full left then full right then straight and drive to 10 mph and the steering angle sensor is calibrated and light will go out. will happen everytime the battery is disconnected.

Thank you!
I just love this website! You all are so unbelievably helpful. I was freaking out there for a moment that I fried my electrical system somehow with a DIY battery replace. My wife would have never let me hear the end of it for being cheap by trying to do it myself and end up costing us a bunch more in the end. Thanks again.

Fromthe operator manual
Regarding PSM failure, here is how to clear it (from the operator's manual):
----
Putting vehicle into operation
After the battery is connected or after an completely discharged battery is charged, the mul-tifunctional PSM light lights up on the instrument panel and a message appears on the on-board computer to indicate a fault.
This fault can be remedied with a few simple steps:
1. Start the engine.
2. With the vehicle stationary, perform a few steering movements to the left and right and then drive a short distance in a straight line until the multifunctinal PSM light goes out and the message on the on-board computer disappears.
3. If the warnings do not disappear, then: Drive carefully to the nearest authorized Porsche dealer. Have the fault remedied.
4. After the warnings disappear: Stop the vehicle in a suitable place.

Thanks everyone for chiming in.
Interestingly. I had a similar story a couple of years ago and recently.
2.2 years ago, battery 3.5 yrs old. Dies, long run around, first you are not the original owner, (lame excuse) then you do not drive enough (average is above 6k per year), then you do not meet the rolling average.
So I buy a P battery at 250 bucks, car at home, use the 2nd car to get it and install it. The usual PSM error clears out in less than a minute.
Fast forward 2 years and 2 months. 2nd P battery dies despite having it on tender intermittently. So I decide to get one from AZ this time.
But since then my navigation keeps "loading". The manual (yes I read it, but only after the error ) said it can take 15 minutes to load
tried driving for an hour. tried disconnecting and reconnecting.
Did not go to the dealer yet as it is my weekend driver.
SO maybe this can be cleared by PIWIS?
any thoughts, input?
