why do they allways pick on us instead of the manufactors, today I have replaced two coils on two cars belonging to every ones car to work on renault 16v, and then we had a vectra towed in by the rac, this being a y reg 2.2 with 47500miles under the belt and bingo the timing chain has gone kaput with full vaxuall service, not much better than the rubber belt + bits, manufactors could not design a garden shed without it braking down & iam dreading can bus and all its promblems. of my box for now. ray
