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
- Internal mechatronic unit fault
- The pump runs, but pressure does not build up or does not hold
What you can do yourself
- Gears and drive may be lost — do not drive
- Check whether the main 30 A fuse keeps blowing
- Mechatronic unit repair — only by a technician
