My 06 has 247k miles. I bought it when it had 123k in 2012. Lots of work to keep it running, I was able to save $$$ by doing it myself, but still, come on VW:
Dual mass flywheel
Camshaft (replaced with the one franko6 is offering)
Both axles (raxles)
Both LCA
Suspension
2 RCV valves
1 AC compressor
Cooling fans
Multiple errors caused by the windshield nozzles heating harness being too short at the hood hinge, wires snapped and caused and electric short (took me more than one year to identify)
Re-circulating flap motor (behind the glovebox)
Windshield wiper motor (a pain to remove)
Auxiliary heating element (removed and re-soldered resistors)
ABS error caused by cables under front seats being too short (Sloppy repair done by dealership during the recall)
3 bent rims, like they're made out of cheese.
Corroded audio cable that goes from the radio to the amplifier (under the carpet)
Battery drain issues (driver side front and rear locking modules. Intermittent and annoying overnight battery drain, killed the battery, had to buy a new battery.
Sticking hand brake (removed the center console and adjusted the tension nut).
Replaced frozen rear caliper.
All of the above before reaching 150k.
Currently leaking EGR cooler and some sort of issue with the steering rack. I will end up replacing both of them. Also, I will need to remove the whole front end of the car, just to replace the AC drier. This car always has something that needs to be fixed.
Previous owner had to change the driver door harness, ASV and turbo.
In addition, the normal maintenance, tear and wear expected from such a high mileage: 2 timing belts, rear and front rotors/pads, DSG fluid changed 3 times, and 4 wheel bearings.
Aside from the expected maintenance, I was expecting more reliability from VW. Thank God for the people on this forum and the DIYs from myturbodiesel, for helping me correctly diagnose and solve the issues I have encountered over the years.
One last thing, as you can tell from my avatar, the MPG is good, but not great.
