ABC accumulator replacement
Hi everyone....
A few weeks ago I made a post about some issues I was having with my ABC. Based on the symptoms I described, a number of you suggested that it might be the accumulators. I purchased a set and will be arriving soon. I've seen a few videos on replacing the rear accumulator and how the mechanism works. While it seems to be tight in there, it seems pretty straightforward. But what I haven't seen is how to replace the front. The posts I've seen all say that it's easier but I haven't been able to find any videos or pictures on what I should expect. Is it pretty straight forward?

The accumulators arrive tomorrow but it's around 105 here in Texas so I'm going put the SL on the disabled list for now and replace them when it cools down a bit.

SL55 AMG
The video provided on the front is really helpful, I have an '07 SL55 with the ABC2 system. From what I have experienced I tried replacing the front accumulator which is a little trickier to access and is not house on a mounting bracket. I have a 27mm wrench, but I can't seem to get access to it from the wheel well position. Only from the front underside of the vehicle. Wondering if anyone has experience with this or an example with the updated position of the accumulator in the ABC2 system. Thanks in advance!
