  3. Cheap obdii diagnostic code reader is it worth it?

    New Member Introductions
    We've just taken the Passat to a local garage to diagnose an ABS warning light and the result was inconclusive. The garage recommended that we take the car to VW for further diagnostics. Local VW want £80 minimum to diagnose the fault. :cry: I've seen on the Intertubes ODBII diagnostic code...

  5. No ODBII communication

    Volkswagen Passat B5 Discussion

    Volkswagen Passat B5 Discussion
    Will a Vag-com tell me more than a ODB2 scanner?
  8. ODBII cycle?

    B5 Garage
    Have a question: how long does it normally take for the ODBII to 'cycle?' Reason being is that I cleared my codes last Wed before cleaning the TB and MAF on my 1.8T (problematic CEL). I've driven 275 mi. since, in both longer trips and in stop-n-go traffic. Before the cleaning, the CEL would...
  9. Tech Help needed - Throttle Position - ODBII vs. VAG-COM

    Volkswagen Passat B5 Discussion
    I've been using a friend's generic OBD-II scanner to help tune my car. 1. It has already provided some benefits vs. VAG-COM, most notably being able to see the Short-Term Fuel Trims (STFTs). 2. And now I know incontrovertably that the VAG multiplicative/learned trims are identically equal to...

  11. VAG or ODBII Question

    Volkswagen Passat B5 Discussion
    I am new to this but I would like to diagnose my own problems with my VW. Is the only difference between the VAG and OBDII the software. If that is the case, then can you buy a cable to connect your Laptop to your car and get the shareware version of VAGCOM. I see people with directions on...
