Issues with 2017 Q5 2.0t
I have had my Q5 for almost two years now and it’s just over 100k miles now. It has the 2.0t engine and it’s been giving me trouble. Intermittently it will have a hard start issue and then issues with a rough idle, hesitation, and nearly stalling out. The codes come up as P0171, P0188, and a misfire code that can be for one particular random cylinder or multiple misfires. Sometimes the car will run perfect. Other times it acts like that. I’ve done carbon clean, plugs, PCV, and cleaned my MAF. I did some data readings last night and everything seemed normal. Fuel rail pressure was normal, maf read normal, O2 sensors had normal readings. Just can’t figure it out. Does anyone have anything else I should test? My next thought would be maybe coils? I also have my concerns about the timing but I have no evidence to show that that’s the issue

Here's a local reference on P0171:

Do you know the history of this car? Has it been maintained?

2017 Q5 turbo
I have a 2017 Q5 2.0T with 73K on it. I brought car in for 30K service (mine was at 28K) and complained about the vehicle hesitating when you accelerate. They tested and said they couldn't duplicate and ran scans and said they found nothing.
(You should note that I also had a 2011 Q5 that burned a lot of oil so I've been through the whole thing with oil consumption tests, etc with no results or help from Audi Canada or my local Audi dealer, I don't trust Audi Canada or dealer at this piont.)
2017 Q5 - just at 73k and suddenly while driving the oil light comes on saying we were low on oil and to add 1L, I added a litre and parked the car. The next day, 15 minutes into the drive, the same thing happens.
Found out that the turbo is gone. Replaced turbo and car still hesitates and white smoke everywhere, could smoke be residual? Any suggestion on hesitation or smoke?
