Do I need to think about involving the motor ombudsman?
Bit of a weird one, but advice / experience would be appreciated.
We bought a used 2021 VW ID3 in March 2025 from a large non-VW dealer with an extended warranty (let's call them dealer 'A'). 16 months later (warranty having elapsed), the HUD and infotainment system was delivering messages saying 'warnings and information unavailable' and, basically, most info was missing and some functions inaccessible although car was drivable.
I booked it into a VW dealer (call them dealer 'B') and they told me it was subject to two recalls from VW from BEFORE we owned it - a software update and something relating to a battery cell. Long story short, dealer B still has the car 6 weeks later because the software won't update and they can't work out what's wrong with the car. They have been back and forwards talking to VW in Germany. We have a loan car in the meantime from dealer B (who have been lovely). We are being warned it may be an expensive repair in the end.
So: Should dealer A have known there were recall notices on the car they sold me? They are non-VW and it may originally have been a trade-in to them. And, if the answer is 'yes', are they liable for the costs for this repair? The car is out of warranty. Finally, is this something the motoring ombudsman could potentially help with? Thanks for your time.
