1999 GLS 2.0 m/t
Is the mileage stored in the ECU or the cluster? I need to replace my cluster and don't want to show a lot more miles than what is actually on the car.
The fuel gauge doesn't work and now the trip meter isn't working right.The milage in the cluster; has to be changed through a coding process or you can ship it out, to a specialized vw repair shop like ian @ reflect tuning. That would be the easiest way to do this; otherwise, you would need a new cluster with zero miles or have a used one "zero'd" out. After this; you would need to do a matching and transfer of milage procedure; through the use of VCDS by Ross Tech. It is a time consuming process, which has a certain learning curve to complete and it can be somewhat of a challenge. I would recommend; you have ian @ reflect tuning, transfer your milage reading to the new cluster, cost $50.

By the way; why are you replacing the cluster? What is wrong with it; are you sure, the problem is in the cluster? You might consider; having the cluster repaired and that way, your mileage would remain intact and after you receive the repaired speedo back, install it and be done. It would be: plug and play... repair complete. Many repair shops; replace the common onboard components that commonly fail and thus, you would have a more reliable, speedo with "updated" components. Some offer lifetime warranty on their rebuilds; I think, BBA Reman offers the repair and lifetime warranty service. Installing, a used cluster; may end up failing, just like the original as the onboard parts are old and may fail just like the original soon thereafter.
