my dad has an 190e 1.8 petrol 1990,hes had it from new with no probs.hes now retired and it is only used now and again but its developed an electrical prob.the coil went about 18 mnths gao so it was changed.last week he pulled onto the drive and the car wouldnt restart.another coil.the garage did the diagnostics and replaced the coil again but couldnt find the reason for the failure but did say something was causing it on the car.any ideas what could be causing this???????thanks
