There is a Renault breakers specialist in Accrington, East Lancs near Burnley etc. They also have a garage there specialising obviously in Renaults. Ive never had any work done there but when I went there for some parts they knew exactly what I was after and knew what they were talking about. Its a bit of a treck for you, depending on whereabouts in Yorkshire you are but this is the only place I have seen. I use a small independent garage in Preston that ive been going to for years, and it turns out the mechanic I use served his time at Renault and really knows his stuff. Just find a local garage that friends/family have recommended as most mechanics know something about all cars.
