My car was juddering and then the engine management light came on and the garage said it needed new ignition coils at a cost of £450! I was quite upset at the cost obviously but went along with it. After this happened my car was still juddering, albeit less than before and last Wednesday the engine management light came on again whilst we were 100 miles away from home. The garage came to collect the car that evening and assured us that the ignition coils had indeed needed changing and they put some fluid in for us (at a cost of £18.50) and didn't charge for a diagnostic test again. Well, now my car is juddering more than ever and even whilst waiting at traffic lights it's kind of chugging away whilst it had always been very silent. Now they are saying it must be something to do with the fuel pump. If that's the case then surely we didn't need the ignition coils changing? Is there anything we can do about this or will it just be our word against theirs?!
