Error 974 Powertrain Problem

[Mitrovic]

This morning I wanted to start the car and this msg. did pop up



After the third restart ( key out ) and pressing the screen it did disappear and I had a little drive with no problem.

Any idea?

The Tesla Ranger has downloaded the data and has found some internal error in the "Hauptsteuereinheit" (?). It needs to be replaced. The car is driveable, but not really safe, because the error could come back.
It will be fixed next week.

"Hauptsteuereinheit"

According to Google Translate, Hauptsteuereinheit means "Main Control Unit". So I'd assume that's a control microprocessor somewhere in the system.

Sounds correct to me. The Tesla ranger ells me that it takes him about 3 hours to replace it and he can do it at my place. I might drive to Tesla store Zürich however, I'll see.

Well they changer the PEM and put the new firmware on it.

Drives like a charm, The only thing I noticed about the new firmware is daylight on.
