Engine light came on and the 2001 tdi was taken into the dealership. The dealership identified the problem as a faulty glow plug. Upon trying to remove the glow plug, the dealership broke the part. Now, the only way to remove the glow plug is to tear apart the engine, at a cost of over $1,000. Dealership will not allow me to take the car back either. Called vw customer service and they are fine with the dealership holding my car hostage. Vw must hate the customer.
