Hi,

I am driving a 2008 530i. Car is driving ok-ish but occasionally throws a CEL warning that engine power is reduced and I should check with the dealer. Sometimes, car feels a little bit itchy when driving at constant speed.

I am using Torque in combination with ODB connector and hence have read the fault code. It is listed as P13B6 - Powertrain. I have tried to look for it on the web but am not able to find any reference other than on a Polish site which talks about a knock sensor.

Does anyone have a clue what this error code is about?

Cheers,
Pim.
