Cruise control in 90hp 1.4TDI not working

Peter said:
Yesterday I called a company who service instrument panels (near my home and highly recommended by my Audi dealer). He had never heard of my problem before and gave me a rough estimate of € 150 for the repair (which would have to wait until 2017 as he was quite busy).
I then knew a replacement would be both faster and cheaper and I ordered one (second hand).

It was delivered an hour ago (€ 65 + shipment and incl. 3 months warranty) and immediately installed in the car. A short test drive proved everyting OK, including cruise control.
As an additional bonus I have the old panel to experiment with, play with CANbus, upgrade to DIS, ...

Indeed the guy that flashes ECUs will match the new panel to my car and my keys and I'll also keep an extra ECU with immo disabled.

Hello Peter !
It seems that I have exactly the same problem as yours ! (However I have to check if I also have this P0501 error).
Switches are working fine, I can see this through the VCDS software, but my CC is not working.
My question is, did you buy the exactly the same instrument panel, or a upgraded version ?
Bye

Hi Johann,
I did upgrade my instrument panel to full FIS. I assume it was several months later, as I today have two ATL instrument clusters amongst my spare parts (the one with faulty gateway and one with operational gateway left over from the upgrade).

You do not say whether or not your ECU is receiving speed info. You should check this (the first value in measuring block 006) while driving. You can also have VCDS check/calculate the total mileage of the car. If it is considerably lower than the number in the cluster, your ECU does not receive speed info. My ECU was 15.000 km behind the instrument cluster...

Upgrade to full FIS is attractive if you have to replace the instrument cluster, but It does not matter really: the cheapest option is to buy a non-FIS (half size display) cluster. But do make sure you get the correct instrument panel for your engine.
Regards,
Peter

Hello Peter,
I already have the half-size display on my instrument panel (ref 8Z0 920 900M).
I'll check this week if I can see the speed on the VCDS.
Thanks,
Johann
 
So, here is the results : I have the speed, but CC is to 0.0
