what year, what engine, where in the world is it. if its older generation modules then it could be an easy internal fix. Namely resistors, and MOSFETS. Are you good at soldering?

OK, understood.
The first Touaregs did have problems with KESSY modules resistors and MOSSFETS burning out on the PCB. It has been done before by a few guys here.
Do you have any small electric parasitic draw from your car battery over time? This is a common fault when these components burn out. The fix, if it is the problem, is desoldering these components and soldering new ones back on. A cheap fix!
If it is something else, then I have heard that changing to different rev on modules can give you headaches when trying to pair with the other 5 modules.
