Default M3 GT4 Race Car - Limp Mode

Hi, I'm new here, hello and help!

We run three M3 GT4's and hired a circuit for a test yesterday to try and solve a limp mode issue with one of the cars

The problem happens when you apply throttle on the exit of a corner or a straight so we donít think its G related or a fuel pump issue, this is the third test of the car and the fault has happened at each test.

When the car goes into limp mode, the maximum revs are 1200. By turning off the engine and removing the key, on restart the limp mode is gone but returns as soon as the car is at race speed and the throttle is applied

As a precaution we changed a throttle actuator and the low pressure fuel sensor even though no fault codes for these components were generated

However we do have two unidentified fault codes;



Please can you tell me what these codes are?

Hello and greetings, I do not know the codes that you have mentioned
But I have run into a similar strange problem once before on a E 46
Which shut down the throttle while turning, and left no trouble codes,
The final fix was to replace the pitch and yaw sensor under the carpet
Of the drivers feet...
Later Daze
