Clear the errors and then move around in your drivers seat and see the errors pop up again. if they do check the connections under your seat. I also had a module attached to the underside of my seat which I checked the cabling to also.

hi @a6blacked007so I've had no issues since I last posted....that is until yesterday! I took the car to get cleaned at my local hand wash and i asked them to vacuum the car. I was watching him rest his body weight over the back seat and the centre tunnel and I was thinking to myself if the fault would come back as I've asked my kids to avoid that area for the last couple of weeks. and low and behold as soon as I drove off from the car wash all the errors returned! argggghhh! anyway so I took the back seat off and had another look at the central gateway module as well as all the cabling (by the way mine wasn't bolted down either). but this time no matter what I did I could not get it to stop pinging with errors. an hour later I started applying body pressure to other areas of the car like the centre console and it seemed to replicate the faults but I couldn't narrow the area down specifically to one spot. I was about to start stripping the centre console down thinking it might be a loose connection in the area of the rear ac controls and vents. But....it got me thinking! Every time I was applying body weight to the central console area the other thing my body is doing is applying the opposing force to the drivers seat! so I started moving around in the seat and the dash started to light up! so I got under the seat and just checked all the various connections, everything seemed to be connected, but as soon as I did this all the errors cleared!! so now I'm thinking it might have been a loose connection under the drivers seat all along! The guy cleaning did move all the seats back and forth, so might have loosened something. There are multiple connections under a black plastic cover under the seat. I removed that and checked all the connectors were firmly in place. I've driven 20miles since and all seems to be well again...touchwood! So it might be worth you checking the same connections since you mentioned the errors seem to happen every time you ride up a kerb. Hope that helps!

depends on your issue? are you getting lots of no communication and missing messages errors in multiple modules? I too simply wiggled the connection the first time to see if it was loose but it didnt help the situation. It was only when I went back to it a few days later and I physically removed the module and gave it a couple of firm taps as well as straighten the wiring loom did my issues stop.

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.
