Larry,
Any progress on figuring this out?

Just wondering...

Steve:
Some of these I have an idea, some I don't. I'll take them one by one
Pic #1 0253.jpg: Looks like what is being pointed to is the brake line for the right front wheel, but I am being confused by the image #5. In image #5, it almost makes it look like the rubber hose is connecting to this hose you are pointing at in #1.
Pic #2 0252.jpg: It almost looks like this hose is connecting to the cylinder head. Looking just by the knuckle of your middle finger, is that a small clamp connecting the hose to the head? I am not familiar with this particular hose on a US version.
Pic #3 0251.jpg: That's the one maybe an inch away from your finger? I'd say that leads to a reservoir, it's definitely not high pressure being a braided hose with a clamp on it.
Pic #4, That's the steel and rubber one I'm seeing, the hose is held on with a clamp. It's easy to see in the picture that it's connected to the steering gear box, if you look in the picture just below the exhaust manifold. It's the return hose from the steering gear box, as returns are low pressure and the hoses can be simply clamped like this. The pressure hose is just below it, inside the shielding tube, the connections on that would be the high pressure fittings, not clamped.
Pic #5 is confusing to me, unsure if this is related to pis #1 or not. You can follow the pipe in Pic #1 and it almost seems like it joins the hose in Pic #5 at a clamp of some sort. I'm thinking more than likely the hose in pic #5 actually goes through the front firewall.

HI Larry

I can't help but think this is for the fully hydralic suspension system that many of the Euro models have/had. You mention it is a right hand drive car so I have to wonder this. Whenever I have run in to this hose pulsing every 4 seconds or so it has been because the leveling valves are adjusted too close to the "filling" position or the pressure control regulator in the system oil tank is bad.

The pictures are all of the same pipe unfortunately when posted the order was mixed . Look at the TIP of my finger and view in this order Pic 3,2,6,5,1,and 4

Many thanks for your reply. I think you may be right . How do you fix the problem .Thanks
Larry

Are we not talking about the leveling control I mentioned a few posts back? If so, check out the CD ROM as it has an algorithm for evaluating this system. If you don't have the CD, you can get from MB at 1-800-FOR MERC or maybe here at Fastlane.

HI Larry

To check to see if it is this system just look and see if the car has any coil springs for the suspension, sorry I should of asked that before. If it doesn't then this is the system it has for the suspension. To check leveling valves for adjustment disconnect the rods from the valves and raise (fill) the car to it full up postion then lower (empty) the system by moving the control rod untill the car settles down. This is noraml ride height for the car. On the valve there is a 4mm hole and the control rod has the same 4mm hole, they should line up or real close to it. If it is out of adjustment readjust it and see if it fixes the problem. As for checking the pressure regulator it is a bit more involved and requires high pressure guages to check it but like someone said this is on the 124 CD-Rom. Good luck!

I disagree on the rear coil springs. I'm fairly confident that all W124's chassis cars, regardless of self-levelling suspension still have their coil-springs in the rear.

My wagon and 500E which BOTH have self-levelling also have rear coil springs

I would check to see if your rear struts have plumbing going to it. If it has plumbing, then you have self-levelling (unless you're running air shocks which I don't think anyone with a W124 would do).

HI Neil

The system I am talking about is NOT a self leveling system. This system is full hydraulic and has no coil springs front or rear. This system can raise the car above normal ride height with a switch on the dash. This system is similar to the old air ride sytem on the W100 an W109 as far as height control.

Now I would like to clear something up in my last post I just seen that is in error. Because of this system you must set the ready to drive height with the leveling valves. When you lower the car with the leveling valves it will go all the way down. To set height have someone measure the car as it stills on flat ground front and rear. Once the height is to spec center the valve and linkage like I described before. Sorry for the confusion.

Wow, I never new of any W124 car that had FULL, on all four corners, hydropneumatic suspension, a la Citroen, 300SEL 6.3, and 600's.

Was that a Euro option only? I've never seen one in the US.

It must ride like an improved 450SEL 6.9

HI Neil

Yes this was a Euro option that never made it here in the states. I forgot about the W116 6.9 having this system and yes it is the very same system. As far as the W124 having the system I am only guessing from Larry's description of his car, that in Europe they have this system on the W124 too. The Europeans get all the fun stuff we never see. Ever seen or drove a W107 3.5 or 4.5 with a manual trans? Talk about a go fast car! Don't know if they ever put it in the 560SL but how much fun would that be?!
