Hi there I have an unusual fault on T4 instrument cluster, the vehicle speed sensor does show correct milage in both engine ecu & instrument pack but displays a 6-10 km difference on display. will this definately be a faulty cluster or is configeration fault in display. also if cluster requires changing is it programmable on a Autocom CDP Pro or do I need a vag .com and how is this done, is immo included inside dash.

not sure what you mean zeljolak. I summized that the dash panel is faulty and out of sink with true vehicle speed but are these dash panels plug & play, in other words can I just take a similar dash panel from another T4 or even a golf and fit it. or will I need to reprog immobilizer ect ect has anyone got the procedure for changing a dash/ instrument pack, how you keep mileage ect ect

To swap the dash and reprogramm keys you need both pin codes.
Its easyer to swap the chips.

VW T4 doesn't have immo in dashboard!!
it is in a seperate immobox in the near of the dash,
you simply can change dash.
