See my post "2010 Tiguan Meltdown" which I am now in the process of updating (to add new control arm bushings, front springs and steering bearings). It has been my terrible experience to discover that the Tiguan (at least ours) seems to have a design life of about 120,000 miles (200-210,000 km). Here are its major failures:
- water pump
- fuel injectors x 2
- main engine/tranny seal
- timing chain
- control arms
- steering bearings
- front springs
- intake manifold x 3
If I had to do it all again I would never buy one. If bought, I would dump it well before the 100,000 mi mark.
