I need some advice.... I know nothing about cars & feel as if my local dealer is taking advantage of that obvious fact. I have 04 plate Corsa Energy, it has done just over 17 000 miles. Twice since I got it brand new I heard a rumbling noise so took it in & they replaced the timing chain, free of charge as still under warranty. The said when the warranty runs out it will cost over £400eac time to get fixed. The noise has came back now so I feel like its something that is just gonna keep happening every 6-9 months. I was telling someone about it & they said the timing chain shouldn't need replaced so often. I dont know they are right but if they are does this mean the card is faulty or something?? Ah.... I dont know so any comments or advice would be a real help/ thanks in advance!
