When driving the 607 2.2 SE HDi auto on Saturday just stopped. Dealer reckons it is a new gearbox that is required. Does anyone know where we can get this fixed for a reasonable price. We have had to spend a fortune on getting it repaired recently - the RAC have been called out to it 5 times to it in the past year and each time it costs us about 800 to get it fixed (or investigated) at the local dealer. We are happy with a second hand one if anyone knows where to get one. We are in Fife in Scotland in case it makes a difference to the advice.
