Hi guys,
Got an ABC error message in white colour, pressed ok and it disappeared. Fluid level is ok, no noises. Message did not yet come again.
But I experience a very hard drive if it is switched to sport or comfort. So I guess the pressure went down when I was going over a pothole and the might mean that the rear accumulator is finished or even weak (might have lost some hydrogen already).
Did someone already replace it? I think it should be located in the left rear wheel housing. But question is, if it is possible to change it without removeing the comlete valve block where it is attached to.
Anybody an idea or even access to WIS having the instructions how to do it?
Would appreciate a lot,
Regards,
Micha
P.S:. Found a picture of the Front damper. But how to hinge the valve block so that I can change the damper without removing all the hoses?
And whats about the rear damper? As I think that is my main problem....
Why would you consider messing with ABC and the damper without knowing if a component failure has actually occurred and the ABC system has been fully tested by a dealer/indy?

Because I had an ABC error on the screen and I guess it was when driving over a pothole. There is no extra error code for the dampers so we will see on maximum an error concerning ABC pressure. The car is 10 years old and normally the dampers are supposed to fail after this time.
And...the ride is very hard. I cannot see any difference from Sport to comfort but ok I have no other SL to compare.
Maybe it makes sense to go to the dealer and read out the error message but I think it will not bring much more information on ly costs some money. This is why I thought, changing the rear damper could not be wrong in my case....
Typically, you would see fluid level drop if you have a blown pressure accumulator (sphere).
As always, the best course of action would be have the car scanned with XENTRY….
Mileage?

Mileage is 28000. But some items are might be both a question of time and mileage.

You'll go nowhere without Xentry on these cars
you car also might want software updates
When ABC starts messing, best is a big serious service, that way you won't have another little part messing up in a few month's
I had the same failure in my 2014 SL63 a couple of years ago just out of warranty. I think it’s a known issue but MB has managed to skirt around having a recall. I asked MB to cover it but they said because I didn’t regularly use the dealer for service they declined.
You will know that it’s failed as the car will ride differently and you’ll feel a vibration on cornering.
I think it was a $2k fix.

Have to disagree. It’s not a known issue on the R231’s.
I am currently searching a garage with Xentry to see the exact error code. There was no more error so far and car stays in position over weeks, but I want to be sure. If the idea with the dampers turns out to be most likely,it will be easier to change this part (invest 150 bugs) than doing a service at Mercedes. These guys have also limited knowledge and they want to make great deal. Flushing the systems is one of my action I do every two years. So changing such a damper is no rocket science as long as pump and valve blocks are ok.
