From what I understand from the forums after you have taken off the clamp you twist and pull the plastic cup off there is supposed to be an o-ring there to seal. This is not a vacuum pump but a hydraulic pump and actuator. Be careful it is quite powerful and can really hurt you. Only reconnect the plug when everything is installed (with ignition off). BTW How did you take the rod end and jack end off the mounting Just pry it off

Over the past three years my trunk needs more assistance from me to open even more so when its cold. I believe this will fix it

It always helps to know the year but here goes. There are two different pumps the close assist located above the drivers side rear wheel. The lock-unlock lumbar gas door back up rods some headrests and 95 and up trunk release on some the trunk handle is controlled by it in others it is enabled by the close assist pump in the trunk assist line. The pump also provides back up vacuum when the engine is
Hello Peter Pls advice. So I finally joined the club I bought a 00 S 500 just a couple of days ago. It has 59K miles. I had it checked out at the local MD dealership and was told everything checked out ok. Well already I have found two electrical issues. 1. The trunk will not open. It worked alright when I checked the car out. I had to use the mechanical key to open it the remote or the trunk release
Sarv Show your dealer the 2003 model year overview at mercedes-benz Home of mercedes-benz Luxury Automobiles - the MBUSA site. Note that Pneumatic door and trunk closing assist are listed as standard features and are not identified among an option package. You should have the feature. You may also have in your original paperwork - the records from the purchase of your car - the original window sticker.
Sure thing Below is the write up and instructions to fix it yourself. It closes great but does not open. If this is the case there is a small disc shaped bladder that pops apart. This disc operates with air pressure. When it pressurizes it actuates a pin which pushes the trunk latch to open the trunk lid. Open truk with metal key inside of key fob. (insert metal key in lock and turn slightly counter

Looking for some help my situation is this - the trunk will pop up with the remote switch in the car and the button outside however it just pops up about an inch and wont open all the way. You can not here any pumps running or an air leak. I thought it was the struts that were weak and I replaced those - no change (thought it was their force that actually opened the trunk). So once you manually lift

what do you mean by try putting the tail of the mechanical key pointing either straight to the rear or straight to the front to insert the bladed key I have to put it straight up into the trunk it will only go left or right Ive tried every position with the bladed key to try and unlock the trunk and have had no luck the key just turns freely with no resistance as thou the lock its self is broken. Is
The mechanical key has a blade that you insert into the lock. Sticking off the end of the key at a right angle is the tail. That term tail is being used to allow some orientation for discussion of the key position in the lock. No the key should not turn that easily. Yes it appears that you lock cylinder is broken or disconnected. The key cylinder has two functions. One is to mechanically unlock the
To add to Gabbys suggestion you will probably have to use pliers when turning the manual key as well it turns farther than you think as it is against a spring mechanism which you need to turn it past. And it if has not been lubed recently it will be very sticky from lack of use. This lock cylinder is also backwards and to open the trunk you turn it to the left (counter clockwise) and it does not push
My trunk has been locked for 8 months AFTER WORKING PERFECTLY FINE and I just got it opened today with the help of a locksmith. Everyone kept telling me to go to the dealer and I finally had a locksmith that wasnt afraid to touch it. I own a 99 E320 and the key would not work in neither would the cylinder when I pushed it in to loosen the latch to open the trunk. Also the trunk Latch inside the car

Sorry you are posting incorrect information ... you do not need to press this lock cylinder in .... you turn it to the left COMPLETLEY and the lid will release.
First Im quite sure that posting essentially the same question twice in 5 minutes will get you nowhere fast brads. Post once wait a few hours and USUALLY someone who knows will answer your question. With regards to whether or not to push in while turning the key in the manual trunk lock I disagree with everyone that says you need to do this. When my CPS failed recently and someone (my stupid friend
The metal key is sometimes referred to as the emergency key. When you use the metal key in the exterior lock cylinder in the trunk handle the cylinder may be left in either of two different positions after unlocking the manual lock and the key can be removed in either position. In one of the two lock positions the electrical release will work - in the other position the electrical release will not
Quote Originally Posted by wallyp Insert the metal key. Unlock the trunk by turning the key as far as it will go counterclockwise - tail of the key pointing to the left.

HHHmmmm On my car the lock cylinder key opening is in a plane parallel to the ground.
OK let me try this again - I think that I may have confused a direction... The face of the lock cylinder is horizontal and facing the rear bumper (facing down). The metal key is inserted vertically. In the normal operating position (electrical releases work) the inserted metal key will have the tail pointing to the rear (at your face as you look at it). If you turn the metal key so that the tail points
While it is very possible that the key position is not your problem I want to try one more time... You said I even tried finding the second key position and could not find a position other than tail out that it will come out of the tumbler. My tumbler is vertical and the key is inserted up into the trunk lid currently with the tail either pointing to the rear or front of the car when I turn it counter
Thanks for the warning and confession. Glad after that malfunction that you were able to get out of both the trunk and the locks vise grip.
Well The best way to unlock trunk if anything else fails is to pull on wire that is attached to lock and the latch will release. the wire is going between lock and key hole and is in middle of license plate area so you can drill hole and pull on it and unlock trunk.
It is the actuator on the locking mechanism. I just had the same thing happen to me. There is a leak somewhere. There is a small diaphram that is only held together by compression clips. They are prone to go bad. You have to remove the linning on the trunk lid and look where the actual lock mech. is and you will see what I am talking about. The only way to open the trunk now is with the actual key
I guess this is the problem now...... trunk wont open even when the car is running with a jump start from the front.... Looks like the vacuum leak in the trunk locking mech. Now the question is How the trunk can be opened so I can change the battery It wont open with key..... It wont open with remote..... And wont open with the switch on the driver side door switch...... Even when the car is running...... Please help. Appreciate your time & help.
Now the path is this. button on the door SAM 2 wire CAN ( here is DATA) CAN module in the trunk electric air valve air actuator lever pop open. Do you hear two hissses... when you press the button on the door Do not even think about making a hole in the key lock and pick the lock. Does not work. You have to reach the lever which pops the fork. ( just a hole and a wire).
I have a problem with my trunk as well and I hope this is not considered hijacking a thread if so I will get out. I do not have the hissing sound. My doors soft close fine. The fuse chart for s500 has Fuse 62 controlling the trunk however I have no fuse or fuse relay on position 62. Does anyone have the same issue. Can someone point me to a DIY for trunk fuse or tell me if they know if there is a way to install a fuse for a missing fuse relay. Good luck on getting your trunk working.
