OK, first off I think I posted this the first time in the wrong forum earlier (sorry), so I am reposting here.

I just replace the dynamic headlight control module in my 01 Allroad. When I got everything back together my Air-Ride Suspension System warning light was on and the system is inoperable and the headlight "Dip" warning is on. Prior to replacement only the "Dip" warning was evident. I know the module was the problem as it had been diagnosed by two separate repair shops. I suspect that I need to return to Audi now to have the ECM flashed to recognize the new module. Anyone out there that can confirm that this the appropriate next corse of action.
