Renault electrics Edinburgh area?

[rick.e]

My son has a 53 plate Clio Extreme which has developed the dreaded emissions warning light problem, but otherwise drives normally. Web searches suggest this can be any one of a number of things, and there are numerous examples of people spending large sums and still not getting to the bottom of it.

Anybody know a good non-franchised Renault diagnostics bod in the Edinburgh area?

Reno Car Care in Trananet are meant to be good or SWR in Stirling.

Both Renault specialists.
