    Will my 20” wheels affect my speedometer?

    I’ve got 20” wheels with 275/40/20 tyres. I’m pretty sure my speedometer hasn’t been calibrated since. Will my speedo be out? I’ve noticed sometimes I seem to be faster than the traffic sitting at the speed limit. What diagnostic tool is used to calibrate the speed VCDS or Carista? Cheers

    Mfd Self Reset?

    This afternoon I noticed that the overall avg. mpg and driving time figures had reset. I haven’t pressed any of the buttons on the display so not sure why this has happened. However, none of the milage counters have reset. Do the counters automatically reset at a certain figure?

    Hi all, i want to remove the Instrument Cluster / Speedo to access the plug on the back side. How is that possible on a T6 Kombi/Transporter? On the T5 there are only 2 screws and you could pull it out. Thanks in advance.

    Am I Being Thick . . . .

    I'd assumed a Kombi LWB with -40mm springs, 20" rims and 275/40 tyres would have a lower overall height than the equivalent VW Sportline Looking at the wheel and rim calculator thingy, I'm not so sure now, unless I've done something wrong. Which would have a lower total vehicle height ?? Just...
