A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- A button is stuck: dirt or a spilled drink
- Clock spring (spiral cable)
What you can do yourself
- Press the cruise buttons a few times: one may be sticking. If other steering wheel buttons don’t work either or the airbag light is on, it’s probably the clock spring; it is replaced at a service centre.
- Cruise control may not engage. Driving without cruise is not affected.
- Even if cruise engages, don’t use it until it is repaired.
The explanation comes from the error code reference in the AvtoElektrik PRO app.
