2003 SL500 ABS Failure - left side of car lopsided

So I'm having some major issues with my ABS. I had MB in Buckhead look at it and do several fixes while it was under warranty but since the warranty expired, it's all crazy. Since I live and work downtown and my garage is at a strange angle, I need to have my car's "lifter" on all the time so its lifted an extra inch. Over the past 8 months, everytime I go back to my car after leaving it alone for about 2-3 hours, the left side of the car is lower than the right...I get in, push the lifter button and the car rights itself then I push the button again to get the car to lift to the maximum. Something is way odd and when I tried to get my cars brakes and wheels changed and balanced, the shop said it couldn't balance them because of the car kept shifting lopsided.

PLEASE HELP???

 

Are these lifters your talking about the clever Citroen hydro-elastic suspension units that MB do use under licence from Citroen?

If so, it 'might' be worthwhile getting a second opinion as to the state of the lifters and particularly if one is leaking & letting a side down.

I would either go to Citroen who should have better equipment to do this or even an independant suspension specialist.

 

Is it one side only that sinks, does it do it while driving, is there any warning on the dash, is it only one corner that drops, on average the measurement from the bottom of the wheel arch to the ground is 70cm on all 4 corners of the car

 

Still confused

I don't know that much about cars so the citroen note was helpful and I'll check around my city to see if there is a company that can look at it.

I do think that the left front is the area that goes lower but it only happens at rest and there are NO warning lights which I find odd! I did have MB of Buckhead fix the pump and replace something when it was under warranty but when I took it in for service a few months back, the service advisor said it could cost upwards of $5000 to fix/replace it and since just getting in the car and pressing the lifting button fixes it, to drive it until it won't respond...not exactly encouraging news I think?

 

A Citroen dealer will not be any use on this fault, the suspension is not the same and it needs someone with STAR to set the height and bleed or check the ABC in all ways, a valve block on that corner could cause the fault.

On STAR you have the facility to check all the parameters and height checks and it is pointless in guessing

 

TV is quite right of course.

And if your still not happy after that, then try phoning MB themselves for advice the phone no. should be on the back of your handbook.

Have your chassis number ready or they might think your a 2nd hand dealer after free info.
