SL/R230: ABC Problem solved




Also flushed the system, installed the latest filter, and performed the "rodeo" .. The car is back as good as new and I believe the SL55 struts actually ride a "tad" stiffer than before ... which I like - since I always keep the "sport" option engaged ....since new.
Since very little is widely know about this complicated (and potentially VERY expensive) suspension .. It warrants continuous attention and proper maintenance when the first trouble indications occur.

I have 102,000 miles on my 2005 SL55. I drive her 60+ miles a day 5 days a week not including weekend trips. I recently replaced all 4 ABC Accumulators (preventive maintenance) , rebuilt both front and rear valve blocks (preventive maintenance) and did a fluid flush. I did all the work in my home garage with common hand tools. To be fair I am a mechanic by trade (restore vintage race cars) but, I find the R230's to be quite easy to work on by modern standards.
The single best thing you can do for the ABC system is routinely flush the fluid every 20,000 or 30,000 miles. I do mine every 20,000 (every other oil change). Change your filter of course while you are at it. I have instructions in the link in my signature on how to flush your ABC fluid in your own garage with very common items available from Lowes/Home Depot. You don't even need to jack the car up!
thank you
