    '96-2001 VW T4 Module Communication Error.

    I have temp warning alarms and instrument light on since removing the Automatic Transmission. Cant help thinking the ECU cant see the Transmission Oil Temp sensor in the circuit which is triggering the alarm. An auto electrician has checked the Cooling system and all is within spec. Really want...

    '96-2001 VW T4 Module Communication Error.

    Hi Uwe, I followed your suggestions. First checking the "Bypass DoIP" in the options tab, saving, exiting VCDS, running test (ok) Auto scan (ok). Today I pulled the immobiliser and bridged the W & K lines, still no joy. I can open Modules/Channels 15: Air bags 17: Instruments 19: Can Gateway 25...

    2001 VW Eurovan / Transporter T4 (7D) re-coding after auto to manual conversion

    I've done the auto to manual conversion as well. I am waiting on Ross-tech to advise me as I can't access the Engine module or the Auto Trans module to change the coding. I have the professional version of VCDS with the Hex-net adaptor. When I was coding the Instrument cluster today I noticed...

    '96-2001 VW T4 Module Communication Error.

    When using my Hex-net via usb cable it will auto-scan perfect. But when I try to connect to individual module's to program them, it will only connect to 2 out of the entire list. All others throw an error. No Communication with Controller. I have tried restarting the VCDS software, restarting...

    The engine ECU is programmed to the Instrument cluster. So the engine will only start whilst connected to the instruments that came with the donor vehicle. I took everything from the donor vehicle, except for the damaged automatic transmission. So the ECU is now saying there is no communication...

    Programming T4 Instrument cluster.

    Is this something I can do using VCDS? I understand the Engine ECU, Instrument Cluster, Immobiliser, and Ignition Key transmitter all need to work together to get the van running. Crossed that hurdle. I read somewhere on a UK FB page I could use VCDS to do an instrument swap and was referred to...

    Programming T4 Instrument cluster.

    So, can I code out the transmission module as it no longer exists? Can I refit my original instrument cluster, and program the mileage as shown on the engines original instrument cluster? My original Instrument cluster and engine did not have an ECU fitted. It was a purely mechanically tuned...

    My 2.4D AAB manual T4 died a slow death. I was able to find a cheap 2.5tdi ACV complete donor van but it was automatic. The automatic gear box had a catastrophic failure. I was able to retrofit the 2.5tdi and marry it to my manual gearbox but to get it to start and run I had to use the...
