I have an Astra 1.7 CDTI October 2005, which has some problems with the electronics, like every other Astra vehicles... I am tired of paying €50 to the dealer for simple diagnoses. Now I want to invest a cheap OBDII diagnostic cable and do the diagnoses myself. But I do not know which one to buy? Please recommend me a cost-effective one. Thank you in advance.
An OP COM cable would be able to meet your needs. The cable covers almost all the Opel cars and is not only able to analyze and diagnose but also to clear the fault codes. It costs only €19, free shipping on EOBD2. Hope this helps.
