parked my 04 for a couple of days and came back to start it and the view panel read do not move vehicle to low. I pushed the suspension raising button and the car raised but I didn't think that they lost height when parked for a while. Any comments?

Before I lowered the car with the Brabus Module, I never had a problem. But I did have a problem with my S-class before and the airbag system failed and the car was on the ground. If you think there is a problem just take it to the dealer.

Hello Xeron

After a few years with my SL's - and I experienced the same effect. Cool down - it is normal, after a few days the car is going down to the ground. When you enter the car, do you have this nice red message in front of you ? and after rising the car to highest position and then down again - everything is fine ? If yes - then it is ok.

kind regards from France

Check for hydraulic fluid near the car. My 03 SL55 started sinking down onto the right side tires after just a few hours sitting. I used the manual raise button to jack it back up for a few days but then went out one morning to a 3 foot diameter puddle of hydraulic fluid behind the car. It had to be hauled in to the dealer on a trailer.

Regards,

Paul

Has happened to me after car parked for around 3 weeks. Dealer says it is normal.

Since you found a leak that is your culprit. There is also another known problem if there is no leak then a valve in one or more of the shocks is sticking. The dealer can hook the car up to DAS and excerise the valves via the "Rodeo" option. They may also drain and refill the hydraulic fluid.

If that doesn't work, replacment shock(s) will be necessary which includes a new valve(s).

My car has twice dumped its ABC hydraulic fluid - once over the garage floor and once over the road (where, because it was being driven and the suspension was "active", it happened very quickly, from a low fluid warning to "stop!" in a matter of a couple of miles). This time, the ride height was unaffected but there was no longer any suspension damping and the car bounced around on its steel springs - the car felt really weird and unsafe to drive.

In my case, the leak was at the font left of the car where the ABC Control Valve is located, underneath the fluid reservoir. Sounds like your leak is in the connection to the suspension strut or maybe a faulty strut itself.

At about 2,000 miles I too had a ABC line spring a pin hole leak. Keep in mind the pressure in this system is very high (2,000+ PSI).

Any slightly loose connection will leak and it is important to have the dealer check torque on all the ABC lines if necessary.

So, i brought the car into the dealer and they told me it was a transmission fluid leak and not the ABC. They took the car through the "rodeo" and it turned out normal. The thing that blew my mind was how the hell can the transmission spring a leak at some 13 point connector MB part# 140 270 02 50 28

Any idea what part this is?

An automatic transmission works by using solenoid valves which, together with hydraulic pressure created by the transmission pump, control the various functions required to run the transmission, for example engaging and dis-engaging the multi-plate clutches used to direct the drive through the transmission.

These solenoid valves are actually immersed in the auto transmission fluid and the connections to them are via metal tracks which run to the connector. The connector has to seal the transmission to prevent the fluid leaking out. See the picture (connector bottom left).

I have experienced this too, if the car is parked in the garage for about a week without moving it sits very low.

This sounds ugly! My '03 must have been made on a day where there was alot of quality control as I it has been bullit proof. Best of luck
