2002 S500 Rear door close assist problem.

I have a 2002 S500 W220. The left rear passenger door pneumatic close assist AND door lock do not work. If the PSE pump works for the other three doors and the trunk, does it need replacing, or can the system for the non-working door be fixed? If so, would someone please help me with some suggestions? (I love the car, but I can't afford the dealer's prices, and it drives me crazy sometimes.) Thanks

Line Leak

Sounds like you have a leak in the line for just that door. You can probably track it down with a Mitivac or something similar to check for vacuum leaks.
