2006 Audi A4 2.0T Avant quattro 4dr Wagon AWD (2.0L 4cyl Turbo 6A)
Sometimes locks doors when I exit car, even w/ motor running, which should be impossible. Once refused to shift down while passing a car and refused to accelerate in any selected gear except "Drive." Revs would peak at 4k, even with accelerator planted firmly to firewall. Tried every possible position of gear selector and punched the accelerator to downshift during 50 miles of freeway driving, to no avail. After shutdown, no problem. Do not trust this car. Dealer's tech indicates he never heard of such a problem. Dealer is 200 miles distant, and tech doubts problem can be diagnosed, since no warning lights were lit.
Solid, good on curves, fair gas consumption.
Serious safety issue re. failure to shift down. Built fail-safe computer control of transmission and door locks.
