Not able to turn off ESP - Error code C109C29

Post by patrik_w » Thu Jan 02, 2025 5:39 pm

As the title suggests I'm not able to set the ESP in sport mode, or turn it off. This worked perfectly fine a few months ago. Got a readout of the codes today and under Brakes -> ABS/EPS the code C109C29 shows up. Cleared all codes, but still not working.

Does anyone have a clue what could be causing the issue?
