Had the update about a month ago.
Brought the car in on scheduled date. Was told my appointment was the day before. Pointed out the appointment notation in my iPad that I entered in front of them. Was told they tried to call me multiple times, but “my mailbox was not set up”. They had wrong phone #, despite it being correct in my customer record. They finally agreed to take the car, and gave me a Q5 hybrid loaner. Interesting vehicles, especially when you don’t receive any instructions in its use.
Picked up the car after hours. Drove 3-4 blocks until I got a flashing glow plug light, and severe decrease in performance. Left it with them and drove the hybrid loaner home.
Next morning, got a call from service begging for the loaner. Upon arrival at dealership, I was told they could not duplicate problem, but had the vehicle in service checking it out. It was returned to me an hour later with a notation of could not duplicate, but they found soot in some line, and cleaned it. Personally, I think a plug was left loose.
The Q5 seems to idle smoother, has a bit more power, and accelerates better. I have not checked the economy.
