I am looking for an automatic TDI that is capable of at least 40+mpg mixed driving (it is okay if it takes a tune and/or exhaust modifications to reach that goal).
MK4 99-03 : desirable ALH but the 01M are unreliable and expensive to repair/replace, so I want to stay away from those.
MK4 04-06 : has camshaft issue, but using proper oil may prevent it. 09A is much more reliable, and I'd rather change camshaft than transmission.
04-06 DSG Beetles : are these early DSGs reliable? I'm assuming these will net better fuel efficiency than the traditional torque converter design of the 09A.
Are MK5 worth looking into? I haven't looked into them because of their lower fuel efficiency, but maybe slight mods can net 40+mpg in the automatics?
MK6 : this is ideal, but a little over the budget and clean title automatic Golf TDIs seem to be non-existent on the classifieds.
