| C1000 |
ESP/BAS control module (N47-5) or plausibility of ESP brake pressure sensors 1/2 (N34/1, N34/2) |
| C1010 |
Battery voltage too low |
| C1012 |
Battery voltage too high |
| C1020 |
CAN communication overall faulty, faulty protocol |
| C1022 |
CAN communication with engine control module (ME-SFI) (N3/10) interrupted |
| C1024 |
CAN communication with transmission control module (N15/3) interrupted |
| C1025 |
CAN communication with BAS control module (N47-5) not possible due to ABS, vehicle version, wheel speed or brake stop lamp signal not available. If there are DTCs stored in memory other than C1025, these are to be checked first since C1025 can be set due to wheel speed signal missing. |
| C1031 |
CAN communication with engine control module (ME-SFI) (N3/10) interrupted |
| C1100 |
Left front axle VSS sensor (L6/1), open/poor circuit |
| C1101 |
Right front axle VSS sensor (L6/2), open/poor circuit |
| C1102 |
Left rear axle VSS sensor (L6/3), open/poor circuit |
| C1103 |
Right rear axle VSS sensor (L6/4), open/poor circuit |
| C1120 |
ESP yaw rate sensor (N64), open/short circuit. There is no fault with the component if the following plausibility was present after the vehicle was driven through a steep turning curve, vehicle collision or vehicle spin-out on slippery road surfaces. |
| C1140 |
Steering angle sensor (N49), Initialization, open/short circuit. With offset fault: check vehicle tracking and adjustment of the steering box. |
| C1141 |
ESP brake pressure sensor 1/2 (N34/1 or N34/2), open/poor circuit |
| C1142 |
ABS lateral acceleration sensor (B24/2), voltage supply, plausibility, offset. There is no fault with the component if the following plausibility was present after the vehicle was driven through a steep turning curve, vehicle collision or vehicle spin-out on slippery road surfaces. |
| C1149 |

Stop lamp switch (4-pole) (S9/1), plausibility with membrane travel comparison |
| C1332 |
Solenoid valve (BAS) (A7/7y1), open/short circuit, A7/7y1 sticks or vacuum is not present. Allow engine to run for a few minutes in order to build up a vacuum. Should the fault not reappear, erase the DTC. |
| C1527 |
Implausible ESP control function (duration: > 15 seconds). There is not fault with the components; if no other DTC is present, erase DTC memory. |
| C1529 |
Pressurization of system via solenoid valve (A7/7y1) for BAS not possible. |
