The check engine light is on in my 2000 V6 Passat. I am pretty sure there are misfire and secondary air pump codes stored. I bought an inexpensive Creader code reader since the car is OBDII Certified and pluggged it in. The code reader displays "LAUNCH - - -" which is what it should display if there are no code to retrieve. Yet as I said engine light is on so there must (should) be codes. So is this code reader defective or has VW does some odd ball thing and I need a more expensive code reader. I thought all cars sold in US after 1996 had to be OBDII compliant and a OBDII code reader should work in them all?
