I have a 2011 A8, randomly when I drive sometimes the lights describe comes on at the same time. After a few miles of driving they sometimes go off on their own. I took it to a local Audi shop and they didn't really know what it was. I'm hoping someone knows or had this happen before in their D4 here. When this happens, my car rides like a rock and bumpy.

I looked in the D3 forums and saw a thread about brake light switch, but that's just a guess and for a different generation. Has anyone had this happen before?

The following lights randomly come on:

Air Suspension
ESP Fault
Hillside start assist
Tire pressure monitor malfunction
My ACC failed anyways, so I'm not sure if that is part of the symptoms.

MP4.2+6.0

Run a full VCDS scan or equivalent. Not just OBDII (engine only) generic scan to be clear. Anything else is both guesswork and waste of your and everyone else's time--and dollars even first time you throw wrong parts at it. Or, take to indy shop with similar equipment.
