Youtube it or look under or behind the carpet

Did this car come with LED lights? If not that is most likely the problem.

Check with dealer . Some Audis have the speaker as an intregral part of door panel. Have VIN handy

I think you have to partially remove the door trim to get to the back of the handle. I found some potentially useful references on YouTube. Search "Audi door handle removal"

the low washer fluid sensor might be shot. try replacing it. hope this helps.

Audi Q5 - MY 2010
The Service Interval Indicator can only be reset with the VAS 5051 or similar diagnostic tool connected to the data link connector of the car.

It is not possible to have that reset or turned off "Service Due!" without using a diagnostic scantool connected to the data link connector of the car. This is the only one way to reset service due light on 2009 Audi Q5.
