Recently on my 2008 GPW, my driver's side door stopped unlocking via keyless remote. The car will flash, but the interior light will not come on. However, I can unlock the door w/ the key and lock it with the keyless remote. Also, once the driver's side door is unlocked, I can unlock the passenger side door w/ the keyless remote.

I searched the forums and it seems the most likely problem is the door actuator. I've checked all the fuses and tried resetting the keyless remote without any success to resolving the problem.

I took it to a dealer today to see if I could get it fixed since the car is still under warranty. However, they claimed they could not easily find the problem after checking what I think to be the simple stuff (e.g. fuses). Dealer wanted $600 to do an a more thorough inspection to test all the electrical.

I was wondering if anyone could provide any more insight in whether it is a door actuator problem or something more serious?

Thanks!
