Had bad experience of The motor Ombudsman.
When our Cali was written off, we had to purchase very quickly a vehicle.
We bought a 2018 Skoda karoq. it had only7,750 miles from new and was 2 years old.
Various minor issues happened via the on board computer, reported when having a service but the dealer wanted around £200 for doing a diagnostic on car , which we thought was not worth it.
Then on holiday in West Wales November 2022 a torrential evening down poor of rain occurred and next day the car's electrics was dead.
Cut a long story short we had it taken to our local dealer that we bought it from Mon motors in Newport Gwent, where the fun began.
They had it for 1 month and we ended up with over a £4,000.00 bill!
They showed us that water entered via a faulty seam not sealed properly at factory. I kept the old log book of pervious owner as she had the car for only less than a year so wrote to her and she said if was in for water leakage problems but they couldn't find it but being unhappy she exchanged it.
Contacted Skoda and a waste of time just passing 'the buck' and for us to hold dealer responsible and even offered us a Xmas hamper!!! which we declined.
After doing lots and lots of research found many a Skoda Karoq of that year having Water ingress faults in same area that the water goes over the fuses!
As dealer sold me a faulty car and would not help We went to the Motor Ombudsman.
At first they said it was a case that they could help us with, but in the end they did not and we lost due to the fact we had a so called 2 years of trouble free motoring.
So who are the Motor Ombudsman?, who pays for there service? Well it is ALL the dealers chipping in to pay for the service.
Still don't let this put you off, have a go they might tell you like us that it is a case for them to look into but remember where there money come from.
Best of luck!
