loss of power then blower shut off
Took my e55 2003 model out for a big thrash on a cold night it was pulling very hard turning the tyres hard in first and in to second gear with esp on lol i was giving it alot of stick then on the way home i gave it a big hit from stand still to 200kmh then after that i gave it a few hits and it did not feel like it was going that fast i felt like it had lost some power then after a few more hit's i think the blower turned off it would not kick back and it was so so so so slow it was very slow then i just drove it home slow then i heard the sound of the blower turning on and it felt more power full down low then i just took the car home today i drove it again it was a very hot day power felt like it was back to normal it was not pulling as hard as that night but it was very cold that night and today it was very hot so im guessing its just the heat so i guess it's back to normal i think helppppppp guys whats going on i have heard the blower turns off when it gets hot but should the car loss power even be4 the blower turns off like it did to me i felt a power lose but the blower was still on then a few more hits turned the blower off i new it was off coz it felt slower then a push bike lol and it would not kick back

Sounds your intercooler pump failed and your IAT temps caused the SC clutch to disengage your SC to prevent permanent failure. Simple fix with a bosch ford lightning pump on ebay or if your under warranty.

The pump may be on it's way out. So yes the temp sensor tells the ECU your reaching dangerous levels and saves your supercharger. Or at least that the intention of it. No supercharger and night and day difference.
Today you car cooled and maybe the pump was working fine and coupled with not pushing the car hard, kept it running.
You still under warranty?

this is a known and common problem. the stock i/c pump will start intermittant failure before completely going out. this will cause iat's to spike above 140 degrees which will in turn cause ecu to pull timing and boost and dump fuel therefor limiting power. if iat's continue to rise another 60 degrees your s/c will shut off you lose what feels like all your power.
mb will replace your i/c pump with an improved version of the oem bosch pump if you are still under warranty (and maybe if you're out of warranty with a good service advisor). if not the johnson cm30 pump is an improvement and shouldn't cost much more than $150-200 parts and labor (less than $100 if you can diy).

Is your car under warranty? Have you had the car long enough to know if it has ever done this before? Luckily it sounds like your repair should be fairly easy to do. Also, is your car 100% stock?

Same pump, just get it fixed under warranty. You don't need a higher flowing pump unless you have extra cooling mods like a heat exchanger or trunk mount intercooler. That need more flow. If your going to run your car hard all the time for long extended periods than go for the cooling mods. Otherwise for the street your wasting your money and the stock system is fine.

The johnson pump really hasn't been around long enough for anyone to put 50k miles on it and see when it fails. Most of the pump failures were from cars that sat alot and the pump was dry most of the time. The motor in the pump is not what usually fails but the magnetic plastic part inside that spins the water through. It cracks and doesn't spin anymore, that's where the failure comes from. The stock one will be fine for at least another 50k miles. Remember either pump regardless of size will not gain any hp, it's just maintain cooling.
