AS some of you may recall, we JUST had the close assist pump replaced on the car. Now, 1 week later, the trunk is not funtioning anymore. WTF!? My dad is really pissed b/c he just spent 700 dollars to replace the pump that was not covered under the warranty. The MB dealership told him that is was possibly air in the lines? Whatever. This thing is such a lemon I cant believe it! Is this going to be a big deal to fix?

Of course there is air in the lines, it operates on air. These people are thieves, stop dealing there immediately. they obviousely didn't replace the pump they just charged you for one.

I was under the opinion that MB repairs are warranteed for at least 30 days. There are switches and diaphrams involved, maybe they just slapped in a pump without checking. When they last changed mine they hooked up a "mighty-vac" to each line to see if it would hold. The system pressurizes to close the doors, and then reverses to reset the diaphrams. You should hera a slight hiss in the trunk for a second or two after closing a door. I would do the "pull fuse 9 for a few seconds" trick in the trunk, which resets the closing pump.
I dont know what the "air in lines" is, since that is how it functions, get the service manager or shop forman involved!
At least, they were right about the "air in the lines" bit. That's pretty funny. Unfortunately,
they appear to be incompetent at root cause diagnosis. It's much easier to swap the pump than it is to actually find the problem.
I would suggest that you go back to your original thread that you are referring to and read some of the responses. I believe you got a lot of good info on how to trouble shoot the system. Pressure testing, as Peter mentions, is very important it seems to me, since a leak will result ultimately in system shut down (by design).
Sorry about your experience. Since they agreed to take on the problem of fixing the closing system and their diagnosis was apparently incorrect, I would argue that it's only reasonable for any further work (labor anyway) to be on the dealership's nickel. Essentially, it's their fault that the pump wasn't the correct fix.
Or, you should have asked for the old pump back (which was probably perfectly fine), and you could request that they take back the new pump and credit you for costs incurred for the part and labor for installation. You still probably should owe the initial cost of examination, and then you'd owe for other parts and installation once they find the real problem.
RE: At least, they were right about the "air in the lines" bit. That's pretty funny. Unfortunatel
Jamison, you once asked me due to inferrence from one of my posts if my mechanic was competent. Well, it's times like what you are going through where one REALLY learns the deal about their mechanic or shop they are going, too. They're approach, diagnostic skills, experience, if they stand behind thier work. My mech has passed that test time after time, with flying colors. Unfortunately, the car itself has provided him many opportunities to prove himself[B)] You guys bought an early W140 - this is how it's going to be until you get it straightend out. And even then, it's always some little thing.

Did you consided the lower latch being out of place. The unit is held with 2 screws. Mine came loose and would function intermittenly. Once I placed the unit in the correct place and tighted it down, it started working consistently.
