Hello,

I have the Audi Q5 2009, and the problem I am having is the rear passenger door is not locking. At first I thought the system or locking mechanism wasn't working via the fob, but if I'm in the car I can lock it. Then if I let down the driver window, do the autolock for all doors then it is working again. However, every now and again, I can't lock the rear passenger door with the remote fob and it doesn't make the sound any ideas that could be causing this.

I want to get it checked out but they will charge me $150 at the stealership, then will say something like, oh you just need a new battery in your remote or some wire was not connected properly. I'm not understanding why sometimes it work and sometime it doesn't. Anyone know the cost of a rear door lock regulator?

thanks
