Carbon Build Up

Carbon Build Up
I've noticed this problem from some of the other Audi enthusiast sites.
Som mentioned that it's from lower octane gas being put in on the Q. In Canada, only these gas stations are listed as top-tier:
Chevron, Esso, Petro Canada, Shell and Sunoco.
In Alberta, Husky Gas stations carry a 94 octane but it is not listed in the top-tier gas.
I'm just curious, what brand of fuel do you use on your Q?

Re: Carbon Build Up
Used Shell-v-power exclusively. Then all six injectors went at the same time. Dealership said it was from "bad fuel quality" I told him nothing but Shell in the tank. Dealership gives me stunned look.
Since then I fuel up at Costco and use Audi Injector cleaner........run's like a top!

Re: Carbon Build Up
Today, I took my 2010 Q5 in for 55000 service. the delaer called me back and said that they need to keep the car for few days due to carbon build up. They have to take the engine apart . I did not have any sympton, other than once in a while when I started the car, it stalled. Is this normal. What problem would it cause due to carbon build up. Your help is apperciated as the dealer did not provide me with much info.
