Not good, and not unusual unfortunately. Not a Renault-specific problem either, and one which Ghosson claims he is going to sort out
In my opinion there is simply too much reliance on sensors now. I had to get a second opinion on the MG because I had been charged diagnostics for a misfire that my dealer could not trace. The second dealer sorted the problem out (fauly HT leads) but I still needed to pay £65+VAT for diagnostics when I knew that it would not reveal anything
What I don't understand is why marque-specific dealers don't carry sacrificial parts to prove faults. For example, a misfire. Why can't they stock the following and try them to prove which one is faulty:
Then they can say it's definately the
and simply charge you for that. No need for diagnostics, such good old fashioned mechanics
Just my opinion...
