Driving down the highway at 75mph in the CTT and all of the sudden the car almost violently loses power and I have nothing when I hit the pedal, the car downshifts every gear to the redline and i pull over. The check engine light comes on.

I turn the car on and off and have power and cruise away fine, CEL still on, then 5mls later the PSM light comes on. What is going on?

Normally for some reason when I'm on longer highway drivers, the PSM light always comes on and stays on for a couple days then goes away. Why does it do this? Winters coming and I don't wanna be driving around with no traction control in the snow.

Any help would be appreciated Thanks.

So, I need a MAF or a DME control module?

 

Perform adaptation first before anything else.

 

The following conditions must be satisfied to ensure that the adaptation is performed:
- Do not actuate the accelerator pedal (for instance, make sure that there is not a carpet pressing on the pedal)
- Vehicle is stationary
- Battery voltage between 10 V and 16 V
- Engine temperature between 5 °C and 100 °C
- Intake air temperature > 10°C
 
1. Switch the ignition on without starting the engine
2. Using the 9588 Porsche System Tester ll (or PIWIS, or PIWIS 2) perform a "throttle adaptation" under the "System adaptation" section (the notes which follow must be observed).
