GTI injectors

Not sure if this is in the right section (apologies if not) can anybody recommend somebody who can test and possibly refurbish mechanical injectors for a 1989 GTI?ideally South Wales area but any recommendations would be great.cheers all.Dan

I would say you are better off buying new injectors. I have just bought some off ebay. If you cant get them working with redex ect then they are probably knackered !!
