What does this fault code mean?
The instrument cluster (DIM) has detected a fault in its data memory, the part where it stores its information. This is an internal fault in the instrument cluster and not a communication problem with other modules. It can cause faults in the trip computer, the gauges and several other functions.
Possible causes
- The data memory of the instrument cluster is damaged
What you can do
- 1Do not drive the car if the brake pedal feels heavier than usual, the steering lock does not work or the engine starts unreliably. Have a workshop check the car first
- 2Read the fault code, clear it and road test the car to see whether it returns
- 3Check that the fuses for the instrument cluster are intact and that the connectors are fully engaged
- 4If the fault comes back straight after clearing, the instrument cluster is probably damaged
- 5Have a workshop replace the instrument cluster and check that the fault does not return once the new unit is programmed for the car
Symptoms you may notice5
- The engine does not start or starts unreliably
- A text and a warning symbol appear in the instrument cluster
- The trip computer does not work
- The steering lock does not work
- The brake pedal needs more force than usual
General guidance for car owners. Diagnosis on the car can point to a different cause.
