Recently took delivery of a 2018, and I've got errors on ignition that distance warning and pre-sense are unavailable. OBDEleven reports that the ACC sensor is misadjusted.

Called a couple of local (E London) Audi/VAG specialists who said it's a main dealer job. Before I book it in, I dug around on various forums and saw people saying to check if the radars have become unclipped.

Can anyone tell me if the positioning of these looks right? The sensor on the passenger side does look like it might be pushed in on the centre / inner side if you look at it from the outer side. From head-on, both look "ok", but I don't know how they're supposed to be aligned.

Looks like the drivers side might be off. The dome should be roughly in the centre of the grille hole. Do they move if you wiggle them? You need to pull the grilles off and check if they are still in there locating points.

I've had it into Audi Harold Wood who've confirmed it's misaligned. The bumper must have been removed by the previous owner for chip damage repair or something because it's been a reattached a few mm proud on the driver's side, which has left the radar misaligned. It's booked in for getting sorted in early January.
