My passat 118 tsi is 3 years old and I have until the end of this week to extend the factory warranty.
I have had the usual DSG issues and had the clutch changed twice, and also had the mechatronic recall done.

The car has been otherwise fine.
Is it recommended to take the extended warranty? The salesman told me that the clutch issues may not be covered outside of warranty if they recur, but I find this strange considering that it's a known fault. FWIW, my old golf 118tsi developed the fuel injector related piston crack and was fixed free of charge outside the warranty period because it was a known issue.

Are there other issues that passats are prone to that could surface in the future?
Do extended warranties enhance resale value of the car, or make it easier to sell?
