Hi Silver Fox and welcome.
I lived in Glasgow and had two Ex Renault guys service my Clio and laterly my V.S. I don't no if they have all the Renault codes etc. as they only did a service on the V.S. They are honest guys and won't do you down. They are Gough & Thomkins, Temple Road, at canal bridge off Bearsden Road about 3/4 mile north of anniesland cross. Tel: 0141 959 0768
The one I use is an ex RTE based in Dundee, a bit far unless you have friends there or needing an expensive repair which normally does at very competative rates.
Hope that helps?
Brian frm a very sunny and hot St.Andrews
