Just to balance some of the negative stuff-
My '05.5 TDI with DSG now has just over 175,000 miles.
I bought it just under 3 years ago with 28,000 miles on it, and found after the fact, from the original dealer, that the recommended oil was NOT used.
I change the oil at 10,000 miles. The level never changes.
Performance is the same today as when I bought it. So's MPG, about 45-48 with a high at about 50.
The car rattles at idle in Park, stops when in gear. Been doing that for 120,000 miles.
Cooling fans and in-dash fan went out within a week of each other, and the driver's door wiring harness failed 4 months later. All this year.
Outside of that, routine replacement of parts (brakes, 1 set, 1 timing belt) all is well.
That is all.
