My 91 S4 has a relatively low mileage, the instrument cluster surface has a bit peeling off. I am thinking to swap to another used instrument cluster unit from a higher mileage S4, I am wondering if my original mileage can be shown in the changed one?
Cheers.

Nope....it is stored in the cluster and not easily changed. New zero miles clusters had a procedure using the stalks to set the odometer reading but one you exceeded a 1,000 miles or so you had a few minutes to get it right before it was frozen locked in.... you could use the internals of your old unit but that would require taking both apart.

Thanks James. I need to think about it before swapping because I really want to keep the original mileage.

check out the other thread going today "Instrument panel delaminating" much more information !!

Is that particularly difficult to accomplish James?

Good point, very likely could switch the module with the miles memory into a different cluster

You can swap over the pcb inside the instrument cluster, this will give you the new display panel but keep your car mileage and settings.

I did this on mine to change the speedo to Miles and Km ( i.e a UK unit) and keep the car mileage etc in KM.

Hi,
I have the same problem with a S4 - 1991. I found another instrument cluster and I want to keep my km. When you say to change the PCB, is it just the one on the back ? (easy)
because I see another one where the display is mounted and that one seems to be more difficult to change.
Thanks
