I have been having some issues with my RS5 for a little while now, intermittently I will get what seems like every warning/error message appear on the dash, to name a few... Sport Differential/Auto stop start/Parking brake/steering/pre-sense/TPMS/ESC/Start system/system fault can't remember them all, but you get the point.
These will clear themselves after I drive for a bit and turn off/on the engine, they happen sometimes before the car has started, sometimes whilst driving, cold weather, hot weather, dry, wet, sensible driving, sporty driving, it doesn't really have anything in common each time it happens.
I spoke with a friend who runs his own workshop and he plugged it in to his diagnostics, there were errors all over the place, mainly things like U112100 Databus missing message or U112300 Databus error value received. I have attached a report of all the errors that he logged.
He seems to think that it may be a faulty connection somewhere which is why it's so intermittent, I have gone over a bump in the road a few times and it started breaking so kind of makes sense.
Any other ideas on this, absolutely stumped at the moment.
Thanks in advance
