Is there a problem with Passat B6 door release/locks

[itchie]

I've got a 2007 3.2L VSE wagon which I've had since new. Great motor, nice car.

Over the past 3 years I've started experiencing intermittent problems unlocking the door locks (including tailgate - no tailgate lift). This initially started with the rear, passenger-side door lock. At that time all other doors would unlock from the key fob. Then it started working again. Then no door would open from the key fob. The only way into the car was using the "spare" key in the driver's door. That continues intermittently for a few months. Then that problem disappeared (again) for about 12 months and now it's back...again...but different...slightly. Now I cannot open the tailgate lock from the key fob.

The tailgate lock was replaced about 3 years ago when it stopped latching, preventing the tailgate from locking properly. (This may be unrelated as all the other problems relate to failure of the remote unlocking of the door release mechanisms. )

Is this a common problem with Passat door locks or perhaps other VW/VAG vehicles?

The door lock actuator motors in the Golf 5/Passat B6 platform (PQ35/45) are known to be problematic.
I replaced a few in our Mk5 Golf (2006) it haven't had any issues in our R36 (2009).
Once a lock gets sticky it's advisable to replace it sooner rather than later, as if it gets stuck locked and closed its extremely difficult to get at it.
The outer door skin needs to come off to get to the lock actuator, so you need to be able to open the door to get to the screws.

Thanks for your prompt response kamold.

Can you direct me to a you tube (or similar) video showing removal of tailgate lock for B7 wagon?

How similar would the procedure be for a Golf 5 rear tailgate lock?

The tailgate locking mechanism is much more straight forward to replace than the door lock actuators.
You shouldn't have too much trouble with that. I'm sure there is some info floating around there in internet land, and probably even on this forum, I can't look it up for you right now.
