Hello everyone,
Maybe someone can help find a problem at high speed. I have a 2019 Turbo stage 5 with meth. In a track, in Sport + mode and PSM on, when I let go of the gas pedal at 150-160mph, I get PSM and all wheel drive failure and goes to Normal mode. I fix this with ignition off and on.
Any help with this is appreciated.
Thank you very much,

 

Dumb question but have you scanned the car to see what exact codes/data is causing the issue?

 

Yes, the only code is P0105 Manifold Pressure Sensor. Which could be related because now is reading higher boost than stock.

 

What are you using to scan it? There's no pending/temp codes stored?

 

I use a Launch X431 V+ Pro 4.0

 

Gotcha...and when you scan the DME and psm there's no temp codes? That's weird, you'd think something would pop up.

Does it drive any different if you don't shut down the car? Like can you actively feel the fault?

 

It drives perfectly only in Normal mode.

To tell you the truth, I think is the sensor. It probably is a 2 bar map sensor and needs to be a 4 bar map sensor. It’s located before the throttle body so when I close it the pressure increases too much and there is the code.
