I have a 3 year 3 month old Clio sport with 38k on the clock. The gearbox struggles to go into 4th gear and the garage inform me that I need a new gearbox as the synchro is broken.

I expected the gearbox to last longer than this and have told that to Renault UK. They have told me that as a goodwill gesture they will pay £486 inc VAT to have the gearbox removed and inspected but as it is defective they will be unable to refit it. If as I expect there is a defect with the gearbox then as another goodwill gesture they will pay 50% of the £2806 cost of replacing the gearbox with a reconditioned one. Is there anything else that I can do?

I know that I'm out of warranty but surely I can expect a gearbox to last longer than that? The car is driven on the dual carriageway daily by my girlfriend and has a full dealer service history. There are quite a few incidents on the Renaultsport website of the same happening. Do I have any standing with the trading standards "last for the time you would expect and be free from any defects".
