I've got a code for the central lock pump running too long. I can hear a vacuum leak around the drivers door lock. I pulled the door panel off to look for a broken hose, but everything looks intact. I guess the lock actuator itself is leaking. Does anybody know if this is common? Is this a dealer only part? The lock works, but I can hear the air leak when it locks. I don't hear any leak when it unlocks. The passenger side doesn't make the same noise, so I'm pretty sure the drivers door lock is the culprit. All I see in my searches is problems with the pump, but I think mine is OK.
