Important repair hints (!)
There are very often issues with power supply of the units. We always recommend to check:
- 12 V power supply
- electrical earthing (oxidised mass points)
- main relay
Attention!
Currently, faults with regard to the camshaft sensor and the crankshaft sensor can unfortunately not be checked.
