I have been making some enquirys as to the claims of power loss after this MB recall/ECU flash thing. So far i cant find anyone in Australia that knows anything about it.

And to quote Ulrich from Kleemann in Denmark:

"I have not heard about a software upgrade from Mercedes resulting in
loss of power. I much rather think one of the components in your car may
be faulty. What does your Mercedes-Benz dealer say?

Unfortunately KLEEMANN does not offer "plain" ECU upgrades for E 55"

Could it just be in the US that this "detuning" is occurring?

.............Your post makes me very suspicious of Kleemann USA. I have had 5 telephone conversations with Cory and he told me clearly that the problem was world wide and that Kleemann Denmark were currently testing a car they had installed a separate module to overcome the load limit issues. My ECU has been in Cory's hands for 3 weeks now awaiting this "emperor's new module." My sense now is that the tuners can't undo the damage and customers are getting reassuring messages appropriate to their situation. I had a sixth sense about this so I ordered a new ECu which will arrive tommorrow and I'll see what happens. I understand that the new ECU may still have the dreaded new program

You have me glued to the screen now.2k for a new ecu sucks,hopefully it works out ok.

has anyone other than E55/CLS 55 such as SL/S/CL55 owners experienced power loss? I did my K2 on my SL55 after the MB reflash and didn't feel power loss between reflash and k2 upgrade. I didn't dyno my car before so I can't really say how much HP was improved. But i would be surprised that my car is underpowered compared to a non-mb reflahsed ECU bcz it's scarily fast already. btw i spoke to cory and he did tell me I have the new kleeman software.

Im taking my car in today but it has already had the ECU re-flash and it feels just fine to me. No loss in power. I though it felt very slow at Palomar Mt. in San Diego but then I saw the sign that said elevation 6000 ft. and that explained that issue very well.

I spoke to my shop foreman and he said this about the ECU re-flash. He said the ecu needed to be changed to a) change the way the car reads the relay on the airpump and b) make the pump stay on less frequently.

He said that the new relay does not ground the same way the old version did and it does not have a ground in the plug. When changing this the lack of a plug likely will freak out the car if it does not have a new ecu.

In the system it shows the upgrade as nothing more than changing that one item and it leaves all other items unchanged.

Honestly my car feels fine and lays dow tons of rubber with esp off..... just the same as before.

Man some of you guys with the Kleeman stuff are lucky with no problems. I just got the new software from Kleeman and still problems My supercharger isn't engaging what so ever. My friends C320 SMOKED ME! I have totally lost power. I stomp on the car and it won't launch.....it just drags. Running out of options........... Hopefully Corey can give me some good news tomarrow

Ted Baldwin

...............no problem. I'll tell you here. I just went to the parts dept of my local dealer and odered it in person. No questions asked.

My car cant even do a burn out with esp off. It totally sucks. I wonder if the dealership will reflash the old program?

Scruffyone

I did not drive my car enough before and after the dealer flash to feel any difference. My before and after dynos were close enough to be considdered accurate.

i have said it before in other threads but my car to me feels faster and more consistant. My car is stock with only filters with the new upgrade.

x-tian-230k If your car can even do a burn out with esp off then you have problems for real.

jefrose55

have an unmodified 04 e55...shops multiple times this year for tire pressure monitor failure, keyless go failure and rattle in pan. roof....today significant power loss..feels like supercharger not working or engaging. Was considering a new S class...rethinking Mercedes ownership

If you are getting smoked by a C320 or can't do a burn out with ESP off you have bigger issues then getting you ECU reflashed.

Mad TKD

jefrose55- If you are having intermittant cut out after doing 3-4 pulls then its most likely the IC pump. But if it is not working at all then its something else and more serious. If you tell your service advisor and they should replace it. I had the same problem and they replaced it with a newer pump.

Hehe, then what happened to you on the way up?

............Update. I received my new ECU yesterday and sent it to Kleemann. brandom called me promptly today upon receiving thene ECU. Ready for this? Oi turns out the new ECU DOES NOT HAVE the recall software. It has a software that is 2 generations older. Brandon was able to instal the k2/K4 program and I will get the unit back tomorrow. I still need to re-dyno the car anfter re-installing the ECU.

Same here!

BoBcanada

Can Mb do it on purpose so when they test drive E63 it would feel much faster? Just an idea.

Jrocket

Could you please pm me with the details of where you got the ecu and the part number please.

dragonAMG

That makes 3 of us... something is up

Fikse

so your dyno comparison will be between the MB flashed, then programmed by kleeman ecu vs the virgin ECU programmed by kleeman?
