Hi Etch and all. I've just signed up as this was one of the many (prob 200+) threads I read on the internet regarding similar issues i.e TPMS, ABS, Spoiler, Park Brake, Stop Start errors etc. I've been having this issue with my A7 for a couple of weeks now. and after spending almost £400 replacing abs wheel sensors, suspect coolant valves and testing with a new battery...it turns out it was actually the central gateway module under the rear seat or the wiring loom leading up to the gateway that's faulty/shorting. I saw your post re your kids movement causing the glitches and low and behold when I applied hand pressure to the seat and carpet around the area of the module my dash lit up like a xmas tree. worse my instrument panel and mmi was going crazy too and rebooting whilst driving. Anyway I removed the rear bench and disconnected/reconnected the module and so far I have driven 20 miles with no issue. Prior to this I couldn't drive 10m before the car started pinging like mad. VCDS scans weren't really helpful either as they showed intermittent loss of communication/missing messages faults in basically every module. So nothing clear. I hope this helps someone to at least identify the issue. if the module is indeed faulty, due to the programming protection it will require an expensive trip to the dealership to replace and program.
