I discovered this today out of nowhere I can't stop it or see where it is coming from
is there a way to up load a short video?
in the 2nd picture I am pointing to where its dropping but it's from the unit in picture one
it's just spraying
The top picture is your ABC & P/S tandem pump. See if the pump side of the pulley is wet. If so, probably a front seal leak. If not, it could be a P/S or ABC line leaking. Check fluid levels on both to verify which system is leaking.

would you know how to remove this?
maybe I can temporarily fix it ?

That's a gusher. I would look at replacing the entire hose assembly. It is a typical failure point and you can get it online for around $325 shipped. Sell your used line on ebay and you are only out about the same as buying a used damper. There are just the two banjo bolts and the attachment bolt underneath, but access is not easy.

so then nothing wrong with the damper per se? so what's causing this ?
you know that video was taken before
I ran the engine once more and it was even a bigger flow

The Mercedes hose comes with the dampener and they don't offer it as a separate part. My point was instead of paying for a used dampener, you might be ahead paying a little more and getting a new dampener and a new high pressure hose. However, now that I look at that video again, I'm not sure that it isn't leaking at the o-ring on the rear banjo fitting. You might get lucky and fix it for a couple bucks in o-rings.

do you think you can post a picture and annotate where this O ring is ? ?
The hose that attaches to the rear of the dampener has a fitting exactly like the one that attaches the front of the dampener to the pump.
Here is a picture of the hose end, the green ring is an o-ring, there is one on each side of the fitting to seal between the housing, fitting, and bolt:

ok I see that but I can't see how there is two. ? there is definitely one looking from the top like the picture I posted earlier
so it's not welded you say?/ it can be removed so the one on the hose can fit instead? am I getting this right?
No, I'm not explaining it very well. The dampener has a banjo fitting welded on the front end that attaches to the pump. It also has a threaded hole on the back side to accept the banjo fitting on the high pressure line that I showed in my picture. Each of these fittings uses an o-ring on each side as a face seal.
Here is a picture of an assembly with the hollow bolt, this one uses compression washers instead of o-rings,
Yes that little damper tank comes off. Some of them have cracked right where the banjo fitting is welded on, I have seen people repair them successfully, but replacement is always a safe option.

how would you change the O ring ? do I need to remove the pump first or ?
No, as long as you can get access, you should be able to just remove the bolt, pry out the o-rings with a pick, and put it back together with new o-rings.

it's called a banjo fitting ? do you have a part number?

When I had this pulsation damper fail on my 2003 SL55, it leaked similarly. While replacing it, I found a broken support bracket (see pics) that I concluded was related to its premature failure.
While I normally favor buying new (from mercedes) on critical parts, since this is only available connected to a hose that one hopes you NEVER have to replace which lists for $590 and wholesales for $430 https://www.mbdirectparts.com/oem-pa...ine-2303208353 AND since this part can be found on it own used for a 3rd the price https://www.ebay.com/itm/11476414805...8AAOSwezFgdSeG you may want to consider going used in this case.

I don't seem to have any pictures of the bracket in place, but it is a VERY important. Without it (or if broken in my case), the pulsation damper puts a LOT of stress on the point were its banjo fitting is welded to the end of the damper. This is were mine cracked (and sprayed like yours). As mentioned, it is possible that your issue is an o-ring in the banjo joint (seems like it could spray similarly).
While looking for a pic of the bracket, I did find a diy (for removing the tandem pump) that includes a picture of the bracket (still attached to removed damper so it gives some orientation context).
so 230-320-83-53 brought up:
03-06 Mercedes R230 SL500 SL55 AMG ABC Suspension Oil Pressure Pipe Line OEM
this is better than buying the pulsation dampener or would you buy both?
buying the 230-320-83-53 is the ONLY way to buy the damper new, if you want to buy it separately, you need to buy it used. It is just a hollow chamber (no internal parts), so as long as it is not cracked nor has issues with its sealing surfaces, a used one should be ok
I think that your part number would be 230-320-74-53 which lists for $420 and can be had for $325 or so, 83-53 is for the SL55. If you have a VIN I would double check. This hose INCLUDES the pulsation dampener.

My bad, I had the SL55 selected in filters on the EPC. Good catch!
