E55 guys, is this normal?
Ok, after a lot of complaining, I finally got my dealer to replace my I/C pump about 3 months ago. The car was a beast.
However, since the good weather has arrived, I've been driving my car harder, and I noticed that after 3-5 hard acceleration bursts in a row, my supercharger still shuts off
. Is this normal with an updated 06 pump?
I even drove a G55 Kompressor, and tried the same 3-5 hard bursts, and the supercharger was working fine...

For the love of God....GET COOLING MODS!!!!
Serious bro.......
It's gonna get even worse. Not sure about the G Wagon but yours is gonna get worse as it gets warmer.
My breaking point was when a guy in a Maxima passed me and with supercharger off due to heat soak, I barely was able to pass him back. He was all smiling and nodding his head like, "Oh no you did-int"

I was under impression that if I'm not running a larger pulley, I don't need cooling mods. Guess its time for - 10 C cooling mod and a Johnson CM30, there is just no way around it.

I would agree with the need for cooling mods - pulley mod or not the computer will shut down the compressor if temp gets too high and that is easy to achieve in hot weather with just a couple of runs. I have the Code 3 heat exchanger installed and have not had any issues with heat since it was installed. Total cost - about $800 installed and it looks very nice behind the front grille.

There has been a stack of comment on this subject but nowhere (correct me if I'm wrong) has anyone posted that it normal for the S/C to shut off after a short period when all other associated parts are working fine.
So.. Does anyone who had their 55 from new remember S/C shutting off after a few high speed bursts?????

I've had my '06' since new and have never had the SC shut down. I've made multiple hard pulls with the car in hot South Florida summers without a shut down of the SC.
I have noticed that the car feels slower when it's hot and the first summer I had the car I installed a Johnson CM30 pump because I thought the Bosch wasn't up to the task. It made no difference at all. I was just used to the power from the winter months when it was cool.

Maybe a failing intercooler pump??

If stock and the ambient temps are below say 100 the car should really never shut down. I have raced kompressor cars for 45 minutes of absolutely 100% driving and never seen a stock car shut down when temps were in the 90's out.
If you have a pulley and ecu tune that rule goes out the window as the car will likely shut down after several long pulls.
AMG has made the car pretty reliable as far as cooling goes (a stock pulley) and it should rarely shut down. The fact that the G55k worked fine shows that your car has an issue still.
I have had 3 pumps go bad in a matter of a month. Also check the relay that controls the pump as those tend to fail causing the pump to shut down.
Good luck

I would NOT go to moddifying the car in an attempt to fix an OEM issue. Let warranty deal with it. No E55 should be having SC shut off, even if they live in the heart of Africa. Mine has upsized pulley, ecu, etc. and still uses the OEM cooling and no shut off (EVER). There is more to it than a simple pump.

Agree a stock car should not need any cooling mods. In the summer you will feel that the power is not there like it was in the cool winters, but thats normal with any car i belive, maybe FI has a bigger effect.
Best way is to take a tech out with you and reproduce the runs and show him the supercharger shuting off, that is if it is actuly shuting off...

The pump's inherent design is faulty and can/will fail with no notice.
For $135, the Johnson CM030 is a quick and cheap fix.

I've just experienced the same problem...supercharger shuts off after 2-3 hard pulls in the car then resets once the car cools down again. The car is currently in the shop and the problem is a defective Intercooler pump. There was no check engine light but the computer had 2 stored codes. Apparently the stock Bosch pump eventually fails due to corrosion on the innards. I talked with Jerry at LET Motorsports and have ordered a Johnson CM30 IC pump to replace the factory Bosch. From what I understand I should notice a difference due to the slowly deteriorating condition of the stock pump and the fact that the Johnson CM30 is a great upgrade to the stock Bosch pump, flows three times the amount of fluid, lowers IAT's more efficiently than the stock pump and has a quicker recovery time. LET sold it for $175, the stock pump in Northern VA was a little over $400. I'll let you know what type of difference I notice once I get the Johnson CM30 installed and running.

+1. If you're under warranty I would not install cooling mods, unless you have a great relationship with your local dealer and they say "go for it" (and even then its a risk). I have a warranty and I wouldn't do it, FWIW.
Keep going back until its fixed. Take a tech for a ride with you, demonstrate it for them. They'll always say "can't replicate."

It was 82 wonderful degrees here today...thank god (or man) for global warming! So I expect that this summer will be a bit warmer and will see alot of IC shutdown in 100 degreeplus days.

I would go back to the dealer and get it replaced under warranty....I'm out of warranty however and have decided to go the CM30 route. I love stock cars and am only doing this because I don't want to hassle with the OEM Bosch pump again. It seems a lot of people don't know what were talking about with this issue since they haven't had the factory IC pump fail YET! it will...and they will remember this post.

I just picked up my car after the Johnson cm30 install to replace the OEM bosch IC pump that failed. It's running great and no more problem with the super charger cutting out after 2-3 hard runs. I ran it pretty hard up to 130 a couple of times and it seemed to be a bit quicker in the response (this could be in my head since I was driving a Prius loaner). Anyway, very glad to have it back and running properly...if this pump fails I will be sure to update this thread.
Again, if anyone is having a problem with the SC cutting out, it's not normal at all...as many members have said, they run their cars in extreme heat and don't have a problem. Granted the car runs very hot, but this should never happen when the car is functioning properly.
