SL55/63/65/R230 AMG: Anyone know the Part # for the Upgraded Bosch Intercooler Pump

I have heard that Merc changed their design 3 times and have finally perfected the intercooler pump. I have also heard that the newly designed Bosch pump is better than the Johnson CM30.
Anyone have the part number for the new pump?
Thanks

Maybe it will change your minds...
Maybe not.. I am just doing alot of reading and i was positive i want to "Upgrade" to the Cm30, but now I am not so sure its an upgrade...

The CM30 might flow similarly but under higher load and pressure it can’t keep up to the OEM one.
I use a scanguage II and the IAT's skyrocketed when I used the CM30.
The dealer replaced my CM30 with the updated (7th gen) OEM pump and my car picked up 4 MPH at the end of the 1/4 mile. YES that's 4mph or roughly 40rwhp!
If you care about true performance then get the OEM pump. It's hard to feel an actual seat of the pants difference, but a dyno or 1/4 mile trap speed will tell the tale.

I just bought two CM30's, for an upcoming project of mine;
A reservoir tank in boot, with theese two installed, as well as the OEM in front...
Bad idea..??

Now I am starting to find people saying the new updated stock is the way to go. I ordered my cm30 a few days ago. Now i am not sure what i want to do either.
Heat = HP loss on our cars big time!
RENNtech also says the CM30 doesn't work well in our cars for max power.
The pump is easy to swap out and bleed. Why don't you guys test it as well. I could have had a bad CM30.....who knows.....
Maxabo,
I think in your application the CM30 will work just fine.

put the pn 000-500-03-86 into mercedesparts.com and it says for the 2007 - 2010 MB 5.5L V12???
wondering it it's all interchangeable between the IC pumps for the sl55 and sl600?? anyone can confirm this?
