I had the same thing happen and it was the injectors. They can check them to see if they're leaking in a relatively short amount of time and if they refuse they're being lazy. If you have more than one dealer in the area you might want to try another one and just go in saying you suspect it's the injectors. Every time I've gone to mine with an issue that has been diagnosed on this board they fixed it w/o question.

As long as i get a loaner i am not really worried how long it will take them, lol.
Thanks a lot for the replies guys. Gave my 5k oil change in about 5-6 weeks so will ask them to do the work same time.

I was also experiencing occasional start-up problems.
Took my Q5 in for service today but they found no issues with the "injectors".
There were no "DTCS" faults in memory.
But they did find a lag issue and installed a software update TSB # 2023535/2 for engine ECU.
I will give an update to see if this rectifies my problem.

Sorry ... Do not know if they actually performed a pressure test ... I suspect not.
No start-up issues this morning.
The nagging lag issue that I was experiencing 1st thing in the mornings, seems to have gone away this morning but will monitor for a week before I can conclusively say my issues are resolved.

Took my Q5 to the dealer for the 3rd time for bad starts. They are now diagnosing the cause as a faulty high-pressure fuel pump and will replace it. I'll let everyone know if that doesn't solve the problem.

My car is now in for 5K service and I asked about this. Their plan was to drive around and replicate the issue. I have insisted to get the injectors tested. They have said they will try. I am not to worried since i have a 2.0T 2011 A4 as a loaner that I plan to enjoy, lol.
