Owning and working on it
- Rated 400 hp and 354 lb-ft in US trim.
- The US market got the sedan only.
- Runs the DQ500 seven-speed rather than the DQ381 used elsewhere in the MQB range.
- Direct injection means intake-valve deposits accumulate over time. Walnut-shell cleaning is the accepted fix, and each cylinder has to be at valves-closed before blasting.
