Alright boys I'm in a bit of a puzzzle...

Last week I did a new HE and new Bosch pump, new coolant...

Today was a fairly warm and nice day, so decided to go for a drive. After 5-6 WOT pulls, the car bogs down (SC inactive), but as soon as I turn the car off than on, or give it a few mins, the car runs fine!! First instinct would be pump is dying... correct? Not the case because its brand new, and I've had it hooked up for 2-3 15-20min sessions to bleed the air from the system...

I'm waiting for the car to cool down so I can bleed the system again. Could air in the system cause such a problem? Could it be the pump, regardless it works when wired directly?

I don't know if this is relevant but I've smelled oil on a few occasions as well. (Could a leak in the system, eg. surge tank gasket cause an issue like this?)

Any thoughts?

I would like to see the feedback you will get for your issue. Have noticed while you are driving 90 - 100 MPH that the car goes like it changed a gear or as if the TB changed position suddenly ??!!! I have this issue since a while and I got CELL too sometimes. Also, when I get this status, the car loss power and when I drive 10 - 20 MPH I can feel hesitating and bogs. Also, sometimes like the car will shut down but it automatically regain stabilization in rpm. I used to have this sometimes even with the Mezerie pump.

Looks like still air in the system!!? Wtf

You should invest in a scan tool that shows intake air temps.

PS even a stock car will shut down if you do 6 wot runs back to back in the summer heat

Do you have hoses hook up correctly into pump and H/E?

tbal

Really? lol

Bled system for a good 30mins, fluid was clear no bubbles what so ever... Could a leak in the system cause a hiccup like this? But once I turn the car off, than back on, I can do another few pulls...?

tbal

OH SNAP! Never thought about that! LOL

The outlet hose from the Pump should goto the bottom of the HE or top npt?

ruh roh. Interested to see if you have it right just to save me the hassle of making this same thread if I ever have to do this...

tbal

LOL, I will ban myself if indeed I have them backwards. lol

Do you know your IAT? when this happen? That would answer some of your questions. If you don't want to go all out on a log tool,. Just get a Innova 3130 you can log a few things, IAT's being one of them. At least you would know if your pump change made a differences and if your IAT's are high.

tbal

Dont know IATs looking at some obd scan tools...

Reason I did the HE and pump upgrade was because my IAT's were high as I noticed on the dyno...

Air in the system could certainly lock the flow. Like everyone else said, only way to be sure is the Scan tool

Does anyone know the fuse/relay for the IC pump?

According to Alldata, its Relay A, in the trunk (Very bottom). I thought it was a fuse? Can anyone confirm.

I get the feeling their is no power going to the pump, until I get a datalogger to check IAT, going to wire the pump to run all the time and see if that makes a difference. Apparently 03 e55's ic pump ran all the time, but because of quicker failure of the pumps, they were later switched to only come on when sc engages?

sneakyneon

You had to know this was coming....

You need logging software of some kind.

Ive said many times before, You can never fix a problem if you don't what its doing.
First mod should be a least a basic odb scan tool.

LOL... I know I know, I'm being cheap! Thanks for the link will grab that one, was looking at same one earlier...

keith954

Which one would you get? I don't want to get one that has features I would never use, but don't want to get one that doesn't have all the features I could have used.

AMG_RL

have you checked your tire pressure?

AMG_RL

all kidding aside I'd re-check all the lines and bleed the system one more time before throwing money on a scan tool.

E55Dimon

The BS just doesnt end for ya T.

tbal

LOL if you didn't post this I was about to go check the tires ahaha I've heard these cars are finicky with tire pressures.

Double checked the lines, no leakage, system bled to death with noooo bubbles.

Could the relay/fuse for ic pump be dead? Anyone know locations?

Also did I hookup my HE lines correct? Anyone have a picture the car share? Or tell me if the line(hose) out from the ic pump goes to the top npt or bottom npt of the heat exchanger?

tbal

Tell me about it bro the way things are going I might just dump the 55 for a m5 lmao ahaha

tbal

Just got the basic compact one it's 50$ shipped on eBay should be good for basic ****

tbal

So just got off phone with well known Benz speciality shop locally about the problem... Both said sounds like a charge pump issue? Ic pump? Lol

Okay you think you have a bad pump but you have no idea what your intake temps are.IM going to be the first one to welcome you to the 180mm pulley and summer weather inferno you have blowing volcanic air into your engine.

If its 90 out and your running a 180 pulley your car is going to shut down after 6 wot runs.My car is at 105-110 right now off boost!I havnt even engaged the s/c yet.

tbal

Until I get the scan tool delivered yes I wont know the IATs. But pump is working because I had the sob hooked up for 1 good hour last night lol...

Doesn't get that hot here... when I was doing the pulls it was about 16-degrees Celsius so around 62ish Fahrenheit?

Peak of summer it hits 86 tops if that. Welcome to Vancouver haha.
