Can Replacement Speedo Have Mileage Changed

steamship · #1 5th July 2014, 10:36 PM

Noticed that daviesbike is having a spring clean and has a couple of A8 speedos, although I think they're for a D3. It got me thinking since my speedo is faulty. No comms between it and Sat Nav, fuel MPG shows as 200 and backlights temperamental. If I was to fit another speedo, is it possible to code in the mileage that's on my current one, or would I be stuck with whatever the replacement one came with?

Must be able to. I had my cluster changed by Audi under warranty due to a flickering back light and the new cluster had the same mileage on when I got it back. VCDS?

I think that Guys ones are for a D3 Sean looking at them. The D2 FL cluster if I remember is coded to the keys that you have immobiliser wise so if you do try and change it an Audi dealer with full VAS set up would need to sort that bit out to so that your keys talk to the immobiliser - not even sure it's possible but you'd need to ask Audi the question. IT may know this for certain and be along in a bit

Mileage officially can only be changed once on new cluster that has less than 100km on it. If you want it changed later you need to desolder EEPROM, read it in reader, modify data, write it back in the chip and solder it back. On some clusters it can be changed with aftermarket gear like VAGTacho or VAG Commander. If you are swapping clusters it's probably easier to swap eeprom chip from the old cluster into the new one.

Sounds like too much hassle, and don't want to go to the expense of a new cluster. Will just live with the issues. Thanks.

I looked into replacing the cluster on my old D2 as it had a problem with the mileage display, I also gave up due to the hassle factor and put up with the fault.
