Audi A3 2005 Vdo mileage.

[Galee]

Hi there I have a Audi 2005 that I need to change the mileage can anyone confirm the correct way and what chip is inside? I have read posts that it can be done by diagnostics port.
Others say the you need to read the eprom in the speedo cluster then change the value write back then use vcds to correct it the ecu end to the correct mileage. I have taco universal will this do it? Also have USB UPA if not.

The dash details are as follows

80P 920 980 T
KOMBIINSTR VDO H73 0300

Cheers

You have to open dash and find 93C86.
Wenn you post dump file i can changed it for you.
Also you can make it by yourself with tacho universall, read the manuel and yoy see.
