Hi Alan, good question/observation, this is something I have been asking myself lately. There still seems to be a reluctance on behalf of many independent garages in my area to get the necessary equipment and training for their staff. Even my local Renault dealer is struggling, as they only have one mechanic who handles diagnostic work, I know this because a mate of mine's Clio DCI has been in their workshop for nearly two weeks waiting for him to get time to look at it! So yes you could be right there might be "diagnostic only" workshops opening in the near future, in fact I wouldn't be surprised if as usual we follow the lead of the U.S.A. Do they not have dedicated sites to handle each particular repair/replacement, like lube centres and brake centres etc.etc? Cheers, John.
