PUZZLER for you all....! Re: PSE Pump/What the F...!
Okay, you all, here it goes:
I finally decided to install a new PSE pump in my 1999 S-500. I really tried to rebuild the motor, but I was unable to get parts and/or any cooperation from Bosch or anyone associated with the parts for this unit. (More on this later!!)
When I replaced the new pump, the installation went without a glitch. I took pictures before I removed it to insure that I put the hoses back in the right plug. I was able to get the exact one from Caliber Motors in Anaheim Hills, CA for $616.00. The list price for this unit was $770.00 (20% disc!
])
All of the related components that this unit controls work fine as they are supposed to; except for one thing (what else is new!! [!]) And here is the problem - it has to do with the central locking in the doors:
1. I was able to re-program the system to automatically lock at 5 mph - works well. Except for the driver's side door. It does not lock when the car is moving. As a matter of fact, I can't even push it down - takes too much force and it does not stay down. There's so much back pressure that I feel I will pop a diagphram or something. However, if I unlock the doors (doors closed) by using the switch on the console, and push down on the driver's side lock, it goes down smoothly without any effort. At this point, I use the switch on the console and lock the rest of the doors. This is the only way I can get my door to lock when driving the car.
When I lock the doors with the remote control, all of the locks go down without any problem, and the locks open normal as well when I unlock it. The alarm sets, the courtesy/security illumination lights come on, the windows roll up, the sun roof closes all is normal.
What's going on?? Like I said, I took pictures of the PSE pump before I unplugged it and used them as reference when I re-installed it. Before the PSE failed, all was working normal - including the driver's side door lock. WHAT THE F... HAPPENED???[V]
By the way, in case some of you were wondering, PSE stands for "Pneumatische SteuerEinheit".

Rainmaker:
It is in the manual; however, put your key in the steering column to Position 2 (i.e. when all the lights light up on the dash board) and then press the door lock switch (on the console) on the top part and hold for more than 5 seconds. This re-programs the doors to close when the car starts to move[]. Let me know if this works in your S320[]. If you want to undo this, follow the same steps, but hold the bottom part of the switch instead.

Any idea if the mirrors can be set to automatically fold-in when parked?

Actually, the doors lock at 9 mph. You can also program the remote to unlock all doors with one press of the unlock button or just the driver's door and trunk. A second press will unlock the remaining doors.
That would be sweeeeet!!!!!

Yeah unfortunately auto-locking function did not work on mine either. [] I wonder what I would need to upgrade to get auto-locking to work? Or even make the remote only unlock the driver door?

Barry, //S320, and Rainmaker:
Let me quote verbatim what it says in the manual for my 99 S500, pg. 34: "The central locking switch also operates the central locking system. To Activate: With the key in steering lock position 2 hold upper portion of switch for a minimum of 5 seconds. To deactivate: With the key in steering lock position 2 hold lower portion of switch for a minimum of 5 secods. With the central locking mechanism activated, the doors and trunk are locked at vehicle speeds of approx. 9 mph (15 km/h) or more. The fuel filler flap remains unlocked.
NOTES: If door are unlocked with the central locking switch after activating the central locking , and neither door is opened, then the doors remain unlocked even at speeds of approx. 9 mph (15 km/h) or more. Opening a door from the inside at speeds of approx. 9 mph (15km/h) or less with the automatic central locking activated, the door will again be automatically locked at speeds of approx. 9 mph (15km/h)or more".
You know, guys, I do not think it has to do with the location of the steering lock (i.e. whether is on the steering column or not). I think that it has to do with an added feature that they included in the S500 models, and maybe even in the S420's. I am not sure... . Maybe someone that owns a late S320 and/or an early S420 (W140) can tell us if this function works on theirs - let's do a poll?? But I can tell you this - that since I had problems with the PSE pump, all these features common to the S500 disappeared until I replaced the darn pump; therefore, I believe that it depends on the Part# on the PSE (mine: 140 800 32 48)pump or version of the pump. I can tell you that I have actually become sort of a specialist in the functions of this damm thing. It is a very interesting unit and controls a plethora of components in my car. Of course, some of the things that did not work had to do with the fuse it was hooked up to.
If you guys are interested, I can give you a list of things that were going wrong with the car before eventually the PSE pump failed. I believe that you will find it useful whenever a "wierd" event occurs with your car. It is a long story since I did a lot of re-search in various forums and internet re: this particular pandemonious part. I did find several common failures to our S-class cars related to this part. Interested??

You know, it's quite possible... . I was thinking, that whether it would be possible to use a PSE pump from a 96 S-500 to activate this feature? I know that in the pump connector, it is missing some connector posts, but on the plug harness, the wires are there. Maybe this is the reason why in the part number there is an additional number in brackets to denote the version of the pump, i.e. 140 800 32 48 (2)? Does this (2) denotes the version of this pump? And maybe this is the reason why, as in my original question, I am having problems with the driver's side door lock?? What do you think?? I just thought about this: Maybe I will remove the motor out of the new pump, and replace it in the old pump just to see whether this problem with the door lock resolves. Suggestions? The damm thing is just too expensive to mess with; however,... hmmm...?

I have an 1994 S420 German tank and as soon as I get my PSE pump up and running I shall let you know if I have the auto lock function on drive off. By the way I have a possible sorce of getting a replacement motor for the PSE, and it will be alot cheaper than the whole unit. Possibly about $40-60 aussie. If all works good I will post a thread on the whole thing and let all know exactly what to get. And where to get it from..
