Someone please help me. I have been having the supercharger shutoff problem after one pull only up to 120, ran it down the track and only trapped 106 mph and ran a 12.8, the car is mostly stock, only mod is a eurocharged ecu tune, the car is a 2005 with 85k miles on it. I replaced the intercooler pump 3 times already thinking I kept getting bad pumps. I replaced the pump 1 month ago but have not been beating in the car so I only figured out the problem was still present at the track when on the return run the s/c shut off, and yes everytime I changed the pump I had the coolant blead, the pump I purchased was the Bosch 010, I am lost and don't know what to do next, pump purchased at vrpspeed.com

I'm fairly new to the E55 so here are a couple
of stabs at it:
Supercharger clutch possibly on its way out ?
I remember reading something about the ECU monitoring ambient air temp and temp in the intake. Check and make sure your temp sensor near the bumper is intact.
Hopefully, someone with a little more j owledge will step in...

You need to monitor IAT (intake air temperatur) to see if thats the problem,to high temp,torque pro app is a good way to monitor IAT.
its not likely that 3 pumps are bad,are you sure the pump is running when you drive the car? you can also check the clearance between the pulley and magnet if it is to mutch it can disengage,should be around 0.25-0.30mm.

+1 on monitor

Log only RPM/Boost PSI/IAT with torque pro on android with an elm 327 OBDii connector and report back with your 0-120mph findings you will get some help with that info

+2 on monitor

You will know right away if your pump is working or not when you see IAT's get up around 200-deg F. (I think that's when the computer shuts off the SC)

Do what BoostedAero said, except if you have an iPhone you can use DashCommand instead of Torque. They both talk to the elm327 OBDii dongle.

What are some temperatures for reference then?

JoeJErnst

Cruising around should be about 20 over ambient. Sitting at idle temps can creep up to 120 easily if it's hot outside. A full 1/4 mile pull from 0-120mph you can see 160+.

I would say you probably have a pump problem if temps ever get above 185, unless you're doing an extended highway romp.

Don't forget to check the fuse and relay located at the rear SAM in the trunk.

Charger shuts down at 190 temps ..Check to see if you got any Kinks in the lines sir in the system if not bleed properly.All this plays a factor

poor car..

Recheck the connection from the IC>pump>HE>pump. I got heat soaked once by connecting it wrongly.

Started monitoring mine yesterday, with 98 degrees outside I was idling at 120 with stock cooling + purple ice.

I have a 180mm CP and live in FL, can I... THINK that I have a 010, but I can't see the part number... I'm sure the stock system is just not enough. I at LEAST have to split it.

Notdke9fdkfjekrjrkj123

stock cooling system cant handle a 180 cp,it will shut off sc after one pull,bigger HE,split system,engine bay tank,would really recommend a meth kit as they are easy and effective.the ECU will start to pull timing already at 95 degrees if i remember correctly!

MACEDON

The car came with this stupid pulley honestly I don't even want it here it's just a huge headache. How catastrophic is the timing pull?

Notdke9fdkfjekrjrkj123

i dont know how much the timing is retarded,the only catastroph is that you loose Power, not good!!!

BoostedAero

Stage I. 95 degrees F. Retards 3.5 degrees
Stage II. 113 degrees F. Retards 6.3 degrees
Stage III. 149 degrees F. Retards 9.5 degrees

You have been trained young jedi padawan

Dato55

the pump was done at a German car shop, I have an iPhone so I will get the app to monitor everything

oneslow55

FYI ,if the car is tuned thershold is raised .

BoostedAero

There is lots of conflicting information on that topic in itself, from my understanding, no matter even if you are tuned the ECU has safety measures to still pull timing along those same stages despite what the tuner inputs

I would love to hear Tony from RaceIQ to chime in on the topic and would prolly only believe his opinion on the topic... no offense

That is just AMG graduate level material unless you have DashDAQ/Zeitronix supporting your claim

oneslow55

It's pulled around 105 to 110 from logs.You can tell of you even have a dash logger elm or some sort

oneslow55

Your right to much conflicting comments ..This why not a huge fan of forums

OKay so during lunch I went to Publix to get a sub and did some "logging"

120 is idle temp, coldest it will ever be because outside temp is 100Floridian Degrees

One pulls later 134 then immediate cool down

Then I did 3 pulls back to back, 165F max then rapid cool down as I drove slowly.

So for my needs, I do a pull every idk how long, I don't race my car, I kinda just love that OOMPH feeling it gives me. I can't be driving it too fast anyway because police cops always **** on my parade like I'm some god damn criminal for driving faster in a capable adequately equipped car (I am, but the laws can **** OFF)

Debating what my next move should be, a split cooling tank under the hood would be the most DIY friendly and affordable... not sure how effective it will be. I've sorta blown my budget for the next few months simply on repairs, I'm planning $300 a month for this car and I've already spent my budget for the year on repairs alone... and I'm nowhere near done, because the airmatic is calling my name.


All in all this car is a pretty good money pit. I love driving it but my god... so stressful.

Dato55

I bought my car at the worst time possible, I bought it with 59k on it and right after everything just started to break, I have put 15k in repairs in the 2 years I have owned this car, that's why my car is still stock, told myself no mods until car is 100%, I have split cooling and a h/e sitting at home that I wanted to put in to see if that eliminates the s/c shut off but being stock and the car shutting down after 1 pull is making me think that the cooling mods won't help until I figure out what my problem is

LOL! I recognize that feeling! If I'd known in advance how expensive it was to maintain my W211, I'm not sure I would have purchased it. Now, however, I've sunk enough into it that I figure I might as well enjoy it to the fullest. FWIW, the expenses on my W211 E55 are four to five times greater than my W210 E55....

A pull is WOT up to what speed? If your hitting 100mph+ id say thats not bad you must have 010 imo. I had similar stats with just 77mm sc pulley, kleemann headers. And im in new zealand we rarely see over 85f.
