Hello all

The wife and I are driving back from a weekend away and her Touareg is throwing a fit. It started with the tire light flashing on and off, not showing any pressure on the dash for all the tires. Then the thing started beeping and flashing that every assist system was faulting out. Then the dash shut down. I have no speedometer or tach. The heat controls are not working either. The radio and other functions on the screen seem to be working fine. Randomly the dash turns back on beeps, flashes through all the warnings and turns back off.
I have very limited tools on hand but I do have a very crappy multimeter and did confirm that the alternator is charging at 14.8 volts. No fuses appear to be popped. Does anyone have any suggestions on where to start with this?

If you even want to think about doing any self diagnostics, you need VCDS..... your basic tools are useless on this vehicle.
