I've learned Touareg main center bearings typically fail between 40,000 and 70,000 miles. The dealer replaces the whole drive shaft and center bearing for around $1,450.00. Failure can start as a chirping sound, like CV joints going bad, or loud thumps right under your armrest. It is a failure in engineering, design and craftsmanship. The dealer says the rubber bearing can't withstand the torque. Just replaced my second one at 130,000 miles. Who makes and markets cars that over-promise and under-deliver like this? I love the Touareg, never ride it hard, dealer service it exclusively and always garage it. First bearing had to be replaced at 70,000 miles. The second at 130,000. Total to date about $3,000.00 for everyday driving. Nothing off road or rough. Just poorly designed - though I still love the car in spite of this.
