S600 ABC issues

Hello,

I'm very interested in an S600.
But there's no possibility to get a warranty in my country and I'm afraid of ABC issues.
So I'm collecting data regarding ABC issues from S600 owners.
If you don't mind, I would like to know of ABC issues you had on your S600.
Thanks in advance.

Regards,
Mouhamed

Do some searching on ABC in this forum and also in the W220 forum. The systems are essentially the same. There is nothing unique that I know of between the ABC system in an S550 and an S600 in terms of design, function, or reliability. Both are similar to the system used in the W220, though there are some physical differences in the strut fittings.

You will also find information on the system in the FAQs and DIY "stickies" in the blue-backgrounded area toward the top of the first forum page, and more in the W220 S-Class Encyclopedia similarly located in the W220 forum.

I've already read the forum.
There are tons of info about airmatic but much less about ABC (on W221/216 chassis).
Based on my research, it seems that that ABC is more reliable on the W221 chassis. I also think that ABC may be more reliable that airmatic. More costly parts but less issues. This thread is a way for me to try and confirm this point of view.

OK, that's fine - but it would seem there is already support in the existing materials you have read for your postulation that ABC is more reliable than Airmatic, but that parts are more expensive. The fact that the ABC systems on the W221/W216 are essentially the same design as the W220/W215, differing mainly in the fittings of the struts to the chassis, is relevant and perhaps worth a read. Still, I hope you get your concerns answered.

Mouhamed,

I have the abc system on both my Sl550 and S600. My understanding this that cars after 2007 have the ABC 2.0 system which included stronger fittings, more filtering of the fluid and other upgrades components which have made the system much more reliable than that of the Ď02 -06 models.

My 2007 S600 has had no abc problems to date and has 130k miles, however my SL with 40k miles has needed a damper replaced on the combination power steering / ABC pump.

I will say one of the most important things Iíve heard is the regular maintenance of the system and keeping up to date with fluid changes.

This is 100% true. I've been told by knowledgeable sources that the ABC system in the W221 is "10 times more reliable than the W220". Mercedes changed the filter in the system from 10 microns to 3 microns on the W221. My educated guess is that this alone accounts for a huge increase in longevity.
