I've had my 1.9tdi for nearly 2 years, i bought it with full service history at 137k
after just having new belts and water pump
Its now on 164k still no issues mechanically
although I think I've got the sticky viens pproblem
its gets serviced with good quality parts every year, an an oil change every 6months
ive seen pd engines with well over 200k and even one over 400k
so tell me what mileage is on your pride and joy ?
