abc

Got an ABC red warning not to drive the car a week ago. Tried rodeo'ing it but wouldn't clear. Rear N/s stayed high forcing the front of the car to appear low. Front wheels rubbed on the wheel arches when lock to lock turning. Took a hard look from underneath and found the "Level Sensor"...

I recently bought an SL55 and after only a few weeks I started to see the ABC visit workshop light appear in the menu. I Ignored it for a week or 2, but now it occasionally has turned red stating 'please drive carefully' and even said a few times 'stop car to low'. After this light comes the car...

I've just read that a simple test to check if the accumulators are failing is the "Bounce" test. Apparently. with the engine off, if you press down on the bumpers, it should be near rock solid but if the car bounces up & down, the accumulators are tired, so to speak. Once replaced, the...

Hi, I was having filling up the screen wash on my W221 S320 (2006) and I noticed some oil over the opposite side of the engine bay (circled red in picture borrowed from another site). It appears to be a thin coating just below the expansion tank and is over the cables etc that go into the...

The front seems to be diving around a centimeter over night & stays there as for as long as it's parked. Does this mean a dirty valve block?? Is this at a dangerous stage as I have a long weekend drive to Sicily this coming weekend?? I think it's been doing this for quite some time. But, as I...

Hi all I recently changed out all my ABC Accumulators on my 215 CL55 AMG. I made a guide, which should be pretty similair for all ABC equipped cars (230, 220, 215). The 230 will require more effort to get to the accumulators, but after that its the same...

Can anyone send me a link or video or stepped instructions?? I just cannot find any & I've started to remove mine & it's becoming quite tedious; in other words, I'm stuck!!

Thinking of getting a W221 S500 (06 or 07), but am a bit concerned about reliability with all the technology crammed into these cars. Of particular concern is the ABC system as I know this has a terrible reputation on the SL500/55. Is the ABC system on the W221 just as unreliable? What should I...

I'm doing some research on ABC valve blocks and need an old one (Pre 2006) to rip apart. If you are replacing your valve block I'd be interested in obtaining your old non functioning one. Just pm me the details. Thanks in advance. :thumb:

OK My SL55 has always had a habit of leaning to one side at the front after being left for a few weeks and when you get in and start her up the dash would proclaim the car is too low. Press the ABC button and the car rises and all is well... you can drive it normally with no issues and no...

Hi all, After coming from a car with air suspension I'm trying to get my head around how the ABC system's various modes function. In my Phaeton, the air springs are adjusted occasionally to keep the ride high level while the dampers are adjustable and produce a firmer ride when in "sport"...
