    VCDS-lite

    A4 B6 1.8t.
    Hi all,
    Ive had a miss fire problem at high power for a while now, done all the obvious things (all coil packs, all fuel injectors, plugs, emmision hoses, fuel filter etc) and now suspect the fuel pump.
    Downloaded VCDS-lite, connected ok, read the vaults (below), problem is I hit the clear codes button while the engine was running and it immediately coughed and stopped. Now the fuel pump doesent deliver any fuel at the rail. Question is, how does the immobiliser work, does it kill the spark or fuel...... or both?

    So far Ive managed to fix all previous problems with the help from this forum, but not his one, any help would be appreciated.

    clearing codes with car running wont kill anything
    i always do it
    immobilizer will let car run for 2/3 seconds then shut car off
    your G28 (16705) can stop the car from starting.

    16705/P0321/000801 - Engine Speed Sensor (G28): Implausible Signal Possible Symptoms

    • Engine shuts off
    • Engine doesn't start
    • Speedometer inoperative
    • Glow Plug Indicator Lamp (K29) flashes
    Possible Causes

    • Engine Speed Sensor (G28) loose
    • Engine Speed Sensor (G28) faulty
    Possible Solutions

    • Check Engine Speed Sensor (G28)
    Special Notes

    • The Engine Speed Sensor (G28) is also used as a reference sensor for the crankshaft position and correlates with the Camshaft Position Sensor Bank 1 (G40) and Camshaft Position Sensor Bank 2 (G163).
      • When an engine will not start due to mechanical timing or spark/fuel related issues it is not uncommon to set G28/G40/G163 fault codes. The basics should be checked if this code returns after extended craning and a no-start with a new sensor installed.
    • When found in a VW Golf/Jetta (1J/9M) or Audi A3 (8L) with 1.9l TDI-PD (AXR), check TPI 2007067 which explains issues with electro magnetic interference. A modification to the wiring will fix this problem, extensive details can be found in the named TPI. Even though this TPI was originally released for VW Golf/Jetta (1J/9M), a customer of ours came across the same issue on an Audi A3 (8L).
    • When found in a 2004 VW Golf, Jetta, or New Beetle with 1.9l TDI-PD (BEW), check for TSB 2010461 (01-07-45 formerly 97-05-03) or 201463 (01-07-44 formerly 97-05-04) calling for a flash update to the ECU and a secondary ground installation.

    Thanks for the prompt reply, its a relief to hear i havent killed the ecu.

    I've disconnected the fuel pipe from the rail, but with the ignition on the pump doesent pump anything, should i suspect the immobiliser?
