Hello In December 2017 I purchased a nearly-new approved used Audi A4 (17 plate, March 2017) from a main dealer (not local to me). I had originally placed a deposit on a different vehicle but they'd somehow sold it twice, so they sourced a different car (slightly lower spec to what I'd wanted) and we completed the sale. The car was 9 months old and had 14k miles on the clock, and they carried out an inspection service prior to handover. It is on PCP with Audi Finance (VWFS). In the last 18 months, the only thing that's gone wrong was the drivers side window sometimes wouldn't lower (it got stuck closed). I took it in to my local dealership who took apart the door, put it back together after applying new seals/lubricant, and that seemed to solve the issue (done under warranty). My local dealer have also carried out two major inspection services at 33k and 42k miles, plus an S Tronic gearbox oil change, so have had the car on 4 separate occasions in last 18 months. About 3 weeks ago I started getting two errors, sporadically, on my DIS - one saying "Brake servo: restricted. You can continue driving. Please contact workshop" and "Start/stop system: fault. Function unavailable. Please contact workshop" (I'm told this second message is caused by the first - the stop/start system doesn't work if any other issues are detected). My local dealer failed to diagnose the issue as part of the service last Friday, but it was booked in yesterday and today for them to have a proper look at. I've just taken a call this morning - they believe the car was in an accident and repaired (news to me!), and also repaired badly. From their visual inspection so far, they've discovered that there is non-oem wiring on the underside of the bonnet (as it's white, rather than whatever colour it should be), the air intake filter wasn't/isn't fitted right, and the coolant location bung is missing. There was also a suggestion some panels had been replaced (but not clear). The implication being my current brake system fault is possibly related to this botched accident repair... (there is no CAT marker on the car). My local dealership is part of a different group, so they've asked for the details of the original supplying dealer and salesperson, which I've provided. Anyone any thoughts or experience what might happen now? Had I known of the accident repair, which has been suggested to me must have been fairly extensive, I probably wouldn't have purchased the vehicle. It is obviously 18 months (and nearly 30k miles) after I purchased, but potentially I'm looking at having to fork out for a repair that should have been covered by Audi's warranty if they decide it's due to the previous accident (before my ownership). Any advice or thoughts welcome - particularly on whether the issues the dealership have noticed with the air intake filter being incorrectly fitted, missing coolant bung etc. are things they should have noticed on one of the previous occasions the car was in with them, or indeed if the supplying dealer should have on their initial inspection service (I really have no idea how obvious these things would be, but, I was told it was picked up on the visual inspection by their tech).
