I used them once, when I had my Uno and it was playing up and cutting out all the time.
He didn't solve all the problems because it would of been to expensive to fix, he just changed the lamda sensor and put the other cause down to throttle body or a crack in the engine (can't remember)something expensive like that.
I would use him again but I have no problems with my car at the mo
He is very good and is an enthusiast (spelling), just look at the cars in his place.
I think I was one of the first to be used on his diagnostic testing equipment because he has invested alot of money into his business about £3000+ just for this equipment because otherwise closet place round here is Fiat dealership in Colwyn Bay, which is about 1hr drive away.
Only prblem is that its up in the mountains a bit, but I would give him a call see what he can do for you.
His Tel No: 01978 757588
