I have a volkswagon passat wagon. It just reach 70000M and it is 2007 model. I recently check the engine at the dealership. Now they asked me to replace all the following items to fix engine overheat and engine noise that just happen a few days ago.
CYLINDER HEAD, REPLACE INTAKE VALVE CAM CHAIN AND HYDRAULIC TENSIONER SEAL SEAL RING X 2 A SENDER D BOOT COOL.ADD FR ELECTR FAN E ELECTR FAN
All these together will end up 6000K+. It will shoot up to 7000+ if I also change the timing belt.
The car is 2007 Passat wagon. 2.0T 4WD. A month ago there is overheat, the coolant meter shoot up to the red region twice. So I checked with them and they say replace fans and thermal sensor in engine will do the job. That Is about 1500. Then two weeks later, I found engine has a sound that feels like diesel car, but my car is gas. Also there are times I turn off the car but the engine fan is still on for a few minutes which I have never seen bwfore. So they check and say I need to replace bunch of stuff in the engine. I always maintain this car at the dealership and I dont drive as much everyday (about 15Miles normally). So it is unlikely that it will be damaged by my driving habit.
The question is: How long does these components last normally? If I am spending this much money to repair the car. Maybe I should just buy a new one (a cheaper model).
