Looking at a manual 3.0tdi C6 allroad 2006. It's got 114,000 miles on the clock, which may, or may not, be a lot. Trolling around, these motors seem to get no mention of specific weaknesses, so just what can I expect it to do long term? Clutch/gearbox, drivetrain? Long term issues? The car, the air suspension etc, how have the C6's stacked up against the previous C5 in reliability long term. Your thoughts gladly digested!
