Hello all,
Purchased my VCDS so I can intelligently shop for an eGolf, and my friend with a 2014 Q5 with some engine misfire issues came right over once he heard I got it :-)
He had the engine check light come on last year and has been using some additives to deal with (known?) issues with ring failure / wear in this motor. Looks like cylinder misfires (among other things), but might also be downstream issues with vacuum leaks. What's the best way to go about diagnostics for engine issues like this? I'm solid with suspension and chassis stuff, but engine work is not something I'm super familiar with. Thanks in advance, and thanks for such a great tool and forum!
Here is the auto-scan from today:
