My BMW 5 Series broke down last and was eventually recovered. I operate as a Private Hire Chauffeur so my vehicle is my livelihood. The problem is a snapped top timing chain, which I have found out by looking at various websites and forums that this is a major fault with this N47 engine, although my local BMW dealer is not admitting to it. The bill so far is being quoted at £6,500 and are now saying it could be a further week before it could be back on the road meaning that I will have suffering £2,000 in loss of earnings. The car has full service history although I will admit the last one is 800 miles overdue. With access being at the rear of the engine I take it that BMW do not expect problems with this and this part should last the lifetime of the vehicle. Do I have a legal case against BMW for this bill more than possibly a gesture of goodwill?
