My Skoda Octavia has lost all of its odd numbered gears. Skoda originally said it was the mechatronic unit and agreed to change it for a nominal fee even though the car was almost a year out of warranty. This however has failed to correct the problem.

They now say it needs a new gearbox but their goodwill offer is nowhere near as generous and I am facing a very large bill. I cannot help but feel that the mechatronic has damaged the box as it must be reasonable to expect more than 42,000 miles before it self destructs. Any advice on how to put pressure on Skoda to increase their offer?
