2015 Q5 with the 2.0T engine. I noticed in the past 2 weeks that the cars randomly has a hard time starting.
When that happens, it can take 2-3 times to fire up, or, it would start after a long crank on the first time, but hesitate for 2-3 seconds and then it runs fine (as if its missing fule).
But this whole behavior is not consistent, meaning, it can be fine for 4 days (cold and warm starts are right away, no issues). Then one time out of nowhere it happens again. If I shut off the car and start it again, its usually fine afterwards.
I did not notice any issues or loss of power on acceleration.
Took these measurements, if you see anything wrong, please let me know:
