Mercedes Benz C220 CDI Estate 2005 - ESP fault, codes C1036, C1173, C1161 & C1172 #

Year of Manufacture *: 2005

Hi,
I currently have a Merc C220 with an ESP fault displayed in the centre display of the instrument cluster. The car drives ok and during wheel spin the warning triangle will come on and off as normal. I have had the codes checked with the Autodiagnos; there are 4 permanent faults C1036 C1173 C1161 C1172. Has anyone else had similar faults or a fix for this problem.
Thanks
Gerald

Gerald.
With-out knowing the exact system, i would hazard to guess you have two problems.

One, is the column module and hence the steering angle sensor.

Two, lateral acceleration sensor fault.

"I have HAD the codes checked with the Autodiagnos;" does that mean you don,t have a scanner that can read this ? If you can,t see live data i will be guesswork.

Only today i had a SLK which put the ESP light on and it was a very slightly loose connection to the lateral sensor, only found during a wiggle test.

Thanks for your reply the code descriptions are as follows
C1036- Fault in CAN communication with control unit N80 (steering column module)
C1173- N49 (steering angle sensor) plausibility error
C1161- B24/15 Rotary speed and lateral sensor plausibility error rotational speed.
C1172-N49 (steering angle sensor) internal fault.
I have recently bought a second hand Autodiagnos i dont think it can read live data on the ESP system.

Thanks
Gerald

Hi Kevin,
You were spot on with the connection problem at the lateral speed/acceleration sensor. I took the multiplug off the component and sprayed a little electrical cleaner on the terminals. The only fault that remains is C1172 the steering angle sensor. I will replace that and hopefully that will sort it. Thanks for your help.

Regards
Gerald
