hi, i own a 2006 renault grand scenic 1.6 dynamique. from a cold start on a morning there is a sort of bang noise then a rattle for a few seconds. i asked a mechanic friend and he advised it was more than likely the spring in the starter motor broke. with his advice i took it to the garage i bought it from, they said it was not that but the dephaser pulley at fault. the starter motor is covered by warranty but the dephaser is not. i am doubting there inspection as it is a long and expensive job. could anyone please give me some advice as im not clued up to be truthull, many thanks adie bridlington.
