On my SL55 I replaced the PSE pump and I fixed the boot (trunk) lock vacuum leak with epoxy glue. No more problems. The pump was running constantly due to a fault in the pump, not due to the vacuum leak. Basically if the pump senses a leak in a circuit, it will turn off that circuit. So, replacing the PSE pump might just fix the problem.

A dollar wages that it's the trunk lock line where it runs from the body to trunk lid. I would also wager that if you remove/refit the pump fuse under the rear seat in the rear BCM, everything will work two/three times and allow you to trace any leaks. Also don't forget that much of the system is positive pressure as well as vacuum using the same lines.

[@alasdairhompstead7950]

I would also add that you can run vacuum/pressure directly to each line in turn to function test each component. Actual hands on diagnosis takes about an hour and initially only requires pulling the trunk carpet panel and pump manifolds which simply unplug. Pulling each line in turn is asking to break a fitting. If the pump runs, then the chances are it is sound. The system is designed to protect the pump by timing it out if a leak occurs until it is manually reset, which gives the illusion of it not working.

[@jakebarnes9018]

I’ll add that based on my experience with my S600 other common failure points are the lines that feed into the doors, and the trunk latch itself.

Back in September 2008 I purchased a 2001 V12 CL600 Palm Springs car with 92,500 miles for $16,500, in "decent" condition and shipped it to Kuwait, where a new job was waiting for me. I was well aware that this car was going to give me a few monster headaches, but having worked previously in Kuwait 20 years before, I knew that there was an enormous number of independent mechanics with the know-how to fix any Mercedes without having to step foot at the local dealership. Sure enough, a month after I was driving it in Kuwait the engine developed a major oil leak, like 1 quart every 30 miles! The local mechanic where I had initially serviced the car brought over from the dealership their top engine mechanic (an Indian) to moonlight at his shop. Cost me KD 1500 ($5000) but it was fixed. What was wrong with it? They couldn't explain to me in English, it was not the rear main seal, but one of those nights while my car was being fixed I visited the shop and to my horror saw my car's engine's cylinder heads on the floor, along with everything including the intake manifold, runners, fuel injection, water pump, everything on the garage floor as well... and the master mechanic was putting it all back together with his eyes closed, like paint by numbers, like a maestro pianist playing a Mendelsohn overture without looking at the notes! I only wish I had taken a picture! Two days later I got the car back and for the next 5 years it served me quite well without any more engine issues... Electrical problems that cropped up were also fixed at an independent electrician who specialized in Mercedes and BMWs... no big ticket repair bills here either. But, had I used the car in California I would have definitely gotten rid of it immediately. The CL600 was in a class of its own, super fast, super smooth and super comfortable. Did I mention the local Mercedes dealership charged $1000 just to open a file for a car that was not purchased at his dealership, and for the privilege of allowing your car to be serviced by an official Mercedes certified mechanic, gouging Mercedes dealership official repair prices! That same oil leak repair would probably cost me triple if not more had agreed to open an official file for the car! Probably the same mechanic would have worked on it!

Older Mercedes definitely leveraged vacuum actuated all the things. My grandfather had a Diesel Mercedes in the 70's. Among its other problems, one was a leaky vacuum system. The fuel cut-off for the engine was vacuum actuated when you turned the key off. When that vacuum system fails the engine doesn't stop when you turn off the switch. Rather than fix that vacuum system, my grandfather installed a John Deere engine-stop cable and rigged it in place of the vacuum actuator. He got the part from his brothers' Deere dealership. My grandfather went back to Fords after that.

[@Hedonistic0Frog]

It's usually the electric motor that fails, at least in the 90s Mercedes. You can replace the electric motor itself for $40. The door locks in the early 2000s Mercedes leaked regularly but I could take the door lock out, seal the vacuum chamber with epoxy, and put it back in an hour and a half for less than a dollar of materials. One gut wrenching problem was the fuel flap staying locked shut, I had to blow into the line manually to fill it up and drive until I fixed the pump. You can usually hear where the leaks are as well once the pump works.

The vehicles equipped with sensetronic brake control were the e, cls, and sl. The cl never had sbc, you can also tell this is a regular abs unit because it has a master cylinder and vacuum booster. Another dead giveaway was the abs unit having the pump but no accumulator. The w215 has abc suspension which can be fun but no sbc. Those people with the 211, 219 and 230 models that want to change their brake pads, disconnect the connector on the abs unit and/or keep the doors closed. It will crush your fingers if you don’t!

My '99 A4 had the vacuum actuated locks and the pump died after a few months of ownership. At the time I looked into options and found a place where I was able to order just the pump itself and not the whole module, as even then (2003?) the full replacement module was like $800!

Good shout with a smoke machine and a mini vac to try narrow down the leak if you've got a long time before the PSE pump arrives.

Well, this cars are so well thought that when the system sense any kind of leak it can cut the air supply to a this system independently or shut the pump off completely to prevent it burns out. The easiest way to make the pump come back alive is to remove its fuse wait some seconds and reinsert it, then pump and all the systems will come back on and leaking can be properly found.

To chime in on Wizard saying it is the same on most german brand. The soft close feature of 2005-2010 audi a8/s8 cannot be repaired as no softclose latch option exist. A little microswitch breaks and it takes a new latch. Audi no longer sell the latch, and the aftermarket do not have the soft close mecanism with the switch. I have developped a way to fix them and found suitable components as the saia burgess switch isnt advailable anymore. It takes a lot of dexterity and grinding and welding rivets. One wrong move and the latch springs apart sending parts everywhere. As a matter of fact I have a latch coming from california for the repair service this week. Maybe I'll show that one on my channel

The problems with cars like this (as well as BMW, Jaguar, etc) is that they end up on used car dealer lots where people that cannot afford to fix and maintain them are given loans to purchase them. Car breaks and the owner is SOL as they had no idea or chose to ignore how expensive they are to fix. I worked on a lot for many years and I cringed every time they brought in a high end European car/suv as they would almost always be someone that should not buy it.

My father used to call people like that "Hundred dollar millionaires." Unfortunately, it rarely works out for them unless they can fix it themselves.

[@HowardMessias]

Earlier versions, usually a 2 cent diode failure in the compressor. Water ingress! Seen a failed Golf R with the same system, crash damage on driver door, the failed to reconnect the line and you could hear the air leak.

[@digitalrailroader]

I’m not surprised; it’s a complex system and with the age of the vehicle, probably some of those parts are globally NLA. And bi directional control can be exceptionally useful, especially chasing down faults in the body control system. (I’ve got a scan tool that I can individually activate my Buick’s power windows)

I admit that I like older Mercedes. By "older" I mean something around 1990 and earlier.

You could also use a smoke machine just like diagnosing EVAP systems and connect it to each individual branch of the circuit to find the leak before you replace the PSE pump. Obviously the pump is bad but it is possible to diagnose without it.

[@JoelAz909]

Point is the man-hours to diag vs just replace the pump and run built-in diags that take about 2 mins. Could run an easy extra few (or more) hours in diag labor for no necessary reason while the in-built diag will pinpoint the issue with very high reliability.

[@masonzayas8401]

@JoelAz909 that's true. It's a tradeoff between a whole cost estimate and a partial cost, some customers may wanna know how much it will cost them up front rather than pay 2 grand and then need more parts. As a previous MB tech, the diagnosis path will also only tell you which part is malfunctioning, but not anything in between. You could have a broken line somewhere and it will diagnose a certain part as failing instead of the line, only to find out after you replace it.

[@JoelAz909]

@@masonzayas8401 agree. I thought it'd be obvious that an indicated failure could be the end module)device/whatever or the line between and I figured that one would automatically diag the line alone after fail module is found for just that reason ( at least that's what I would do if I was doing the repair)
