Volkswagen T5 adjust speedometer with bigger wheels

[Alexx222]

Hey, how to adjust the speedometer from VW T5?
I have bigger wheels on the T5 and now i need to adjust the difference from tacho speed.
In VCDS i have no options for this.
Have someone ideas what i have to do?

Use a gps to measure you're velocity, do some runs, then use some resistors on the signal wire to adjust it correctly

hey, thanks for your reply but is this the correct way to adjust the speedometer??:02.47-tranquillity:
Is it possible with VCDS or VCP?

resistors? signal wire? this is a can bus system, but even if there is signal wire like in older cars, how will you change frequency with resistors?

resistors and signal wire... please guys:mad-new:
I need a solution with VCDS or VCP

[lucim12]

yes, it worked on older renualts because it was a variable voltage not a frequency or anything, And older mondels did not have can ;) ... if it don't work for you or don't like
feel free to search your own solution :)

Look with VCDS in ABS module. Maybe he can be coded for bigger size of wheels...
