Carbon buildup on intake valves
Often reported
The 3.2 FSI direct injection engine develops carbon deposits on intake valves; this causes delayed throttle response, rough idle, power loss, and occasional misfires.
Engine Internal
Oil leaks and excessive oil consumption
Often reported
Many users report oil leaks at predictable points (valve cover gaskets, seals, and various connections) and in some cases higher than normal oil consumption.
Engine Internal
Worn timing chain tensioner and chain
Often reported
