Front suspension drops .. !!!
Hi,
when I park my car and turn it off for several hours the front of the car drops but when I start the car again for a few seconds it levels to the normal position.
I don't know exactly why this problem occurs is it from the pumps, valves or sensors.
your input is really appreciated.

I had the same problem. Car would drop after one day. Valve block was replaced and all is now good.

operated the up and down buttons about 15-20 times. to change it, i lifted both front wheels off the ground. removed cover on drivers front left side to access the valve. there is five lines on the valve, and four electrical connections. once removed, there is 3 10mm nuts holding the valve to the valve bracket. once removed, was able to removew it. instrallwd in reverse.

there was no pressure, because my opinion the tires were off the ground. i brought mine used off ebay. some may not want to buy used. but im a aircraft mech, so if i can change the part and buy use, i save alot. as far as fluid loss, i would say 1 or 2 liters. im just telling everyone my expieance. you dont have to buy used. i figured if i can save on labor, and buy a used part. if it goes out in a year or so, maybe at that time ill buy one new, or another used one. so. i brought the used valve off ebay from a cl600, wrecked the the rear. the insurance company totalled the car. he took off some parts that he recently replaced, and spent big money at the dealer, and he refused to let those good parts go to the scrap yard. we know what the dealer charges for abc issues. so he pulled some parts off, before the tow man cam. he made alil money, i got a very good used valve for cheap. and we both were happy. i paid 200 shipped for the part, 40.00 for two liters of abc fluid shipped. total cost of my car sagging in the front after 2 hours was 240.00 dollars and a couple hours of my time. thanks to ebay, info fromn this site, someone eles misfortune. alot of homework of my behave. and jusat alil skill. its been 3 or 4 days now. so far so good. I WANT EVERYONE TO KNOW THAT I TOOK SOME CHANCES BUYING THAT USED VALVE, THE SELLER COULD HAVE BEEN DISHONEST ON THE CONDITION OF THE PART. THE REASON IM SAYING THIS IS BECAUSE IF YOU DO THE SAME THING AND IT DONT WORK FOR YOU FORT SOME REASON, I DONT WANT TO BE HELD RESPONSIBILE. im just letting everyone know what i did and my results. i guess this is the disclaimer. lol and if someone wants to call me or want me to help, ill do what i can. i was alil messy because of fluid dripping from the lines, but it was worth it. no lights, no cautions, no sagging. so far so good.

The entire process is outlined fully within the MBZ STAR SERVICE Service Manual Library DVD.
Btw....well done Tony and you can use clamps on the fluid lines to prevent leakage next time.
