Hi, My w221 has got problems with the ABC. There are no faults on the dashboard also not with star diagnose. I can also put the car in higher position and no problems. Rodeotest put out 180/190 bar and holding pressure. What we can find is that 1 strutt is on 60bar and the other 3 on 90 bar. When i drive the car it’s very nervous. And looks like the strutts don’t work because i feel every hole in the way. What do you think?

Mines came on from pushing the gas pedal all the way down. This was my first time seeing the ABC light come. It said stop the car. I stopped the car, shut it off, and then turned the car back on. It went back to normal. Also it’s a 2008 s63 amg❤
S63 w221 I noticed hydraulic house had a pin hole and was leaking oil. I noticed this as a coincidence was looking at something else. I got the hose repaired at a hydraulic shop and so far all good. Taking it off was a bas…::: I had to cut the torx 40 socket to fit in the gap.

Where do I add the hydraulic fluid? Can I do that where the dipstick is at? Thanks.
Yes in the all the dip comes out, be careful not to overfill it, especially if the engine is hot because the fluid will expand

Hey having the same problem did you end up fixing it and what was the problem
@@jamesbaker7689 pretty sure that this has something to do with one of the 2 pressure accumulators. look it up.
Tandem pumps can be rebuilt for a fraction of that cost, there are plenty of companies that do it
