  3. How to "fool" the ECM while removing the coolant tank. B5 1.8T AWM engine

    B5 Garage
    It has a 3 pin connector and I would think that probably there is already cooked by someone in the forum to be able to stop the ECM from panic attacks when sees no coolant in the tank. Now working with the engine speed sensor and removing also the oil filter. The filter definitely will go back...

    Vag-Com and OBD11 Coding
    I have a new to me 2000 VW Passat Wagon 2.8L V6 5spd. I am replacing the engine computer with a used unit. The old computer is bad with a burnt circuit board. I have done a little bit of research and have concluded that the registered version of VCDS should be able to program the immobilizer...

    I have a 2001 (B5 I believe) Passat with the V6. This spring I started having intermediate starting problems and the transmission would go into safe mode. I believe I now have the problem tracked down to a faulty ECM (engine control module). If I try to start the car the engine will crank but...
  12. Any way to tell if my B6 has upgraded ECM?

    Volkswagen Passat B6 Discussion
    Thanks to anyone looking at this. Last week I bought a 2010 Passat Wagon. It came with DRL disabled, H&R Springs, and Koni Shocks. It runs pretty well and I was speculating that it might have had the ECM flashed/modified. Is there any way to tell? Maybe using a VAGCOM cable?

    Hi all, So my ATQ 2000 passat 5spd has been throwing the p0431 p0421 codes for a while, no gas mileage and power loss as far as I can tell.
