Gearbox total failure (components punched hole through casing), including fly wheel and clutch at 36000 miles (covered under warranty-Just!)
Mid row rear seat belts always rattle after use - a small but very annoying design fault as the buckles have to be manually moved up to their top position to stop them rattling against the doors - kids never do this!
Normal problem with rear wiper not working unless the boot door is absolutely shut tight.
Alarm goes off on own accord - 3/4 times annually.
Electric windows have all opened on their own overnight.
At 47000 and just over four years old, despite me having full main dealer service, and despite mentioning the slowly increasing whine from the turbo at every service (only to be told it's within tolerance) the turbo has failed, sucking debris into the inter-cooler. Very big bill on its way.
I needed 7 seats for the family, and the Touran gives me this together with excellent fuel economy and good handling. Generally, over the last four years the car has been enjoyable to drive.
However, I went for the VW because of reliability and resale values, but this car has totally let me down in a big way twice. I am presently trying to get a dealer contribution to the turbo replacement, and if not will take out action under the Sale of Goods act for a car that is not fit for purpose - turbos and gearboxes on a fully serviced car should last longer than mine have!
I think they must also have Monday cars in Bavaria?
