bought my 2002 v6 clio from a renault dealer 8 months ago, 2 months later i had the coils go, my mate who has a toyota garage stuck the diag''' machine to prove this... went to renault to say what the problem was and they turned round to say they had to do the diag'' test at a cost of £30 to prove the fault...... anyway, long story short, a few f's and q's and "c u next thursday" later and they replaced them under warranty. ......................................................................................................................... same happened last week... i told them to replace the lot when it happened at first !!!!!!!!!!!!!!!
