On my 2011 N55 335i I had the voltage changed by a local coder using the files downloaded from another forum. All was good after that, no codes.
Coding Higher Voltage Limit to Avoid 2AAE Fuel Pump Error Code
- Thread starter Jeffman
- Start date
So is the consensus that this code is a non issue and can be eliminated by changing the coding or is it indicative of an issue? I get it quite a bit after a WOT pull, and figured it was just a 'normal' error that could be cleared and ignored. I only have a PR Stage 2 pump. Could it be that my EKP is weak or dying?
It's normal, or at least common when people upgrade to the Walbro 450. Coding it fixed it for me, my coder (N54 owner) was skeptical and thought for sure my EKP was bad but I have not had any issues since he coded it. I am N55 so no LP sensor but I will be installing one in a replacement fuel line and a FP gauge as soon as I find the time.

I’d like to code a higher voltage as well using the ProTool app. Can you give a little more info where to look there? Thanks.
Anyone try playing with different characteristic curves with an upgraded pump? Was wondering if one might have less pressure fluctuations than another

The option does not show up unless you have an EKPM3 installed.
I installed an EKPM3 from eBay and coded it with ProTool. Seemed to solve the voltage issue until earlier today when the car wouldn't start back up. Got the lift light on the dash and an LPFP code. Cleared the codes, swapped back in the EKPM2 (I luckily kept in the car), and it fired right back up.
I'm thinking bad EKPM3, but would appreciate additional theories before I move forward.

Did you buy a used one again from ebay cause i am in the same boat right now, also the one i bought is for an f10 m5, would it work?fixed with a new EKPM3
Yes @Mzfhartge, the second one was also from eBay. It's hit or miss.
FWIW, the new module is an EKPM3 with `FSV 5.32.97`. The previous one was `FSV 06.00.03`. My thought process was it was manufactured for a closer year (I'm 07 e90), but I could have just gotten a bad module the first try. I'd definitely recommend getting another one before you go down any rabbit holes.

Ok let's see if we can get this nailed down with others:
- I have not seen anything that indicates that the EKP's will not work across various cars and versions of EKP.
- From what I understand coding is ONLY required if you are moving from EKPM2 to EKPM3 (and the other way)? And this may not be the case (someone say otherwise).
- If coding for same version, largely done so VIN in the module matches, and BMW software portal updates can be performed properly.
never seen this before, would have loved to play with it to figure it out but on the other side of the world.
its working now maybe a dead ekp, stranger things have happen.

I use proTool on my tablet. If you install a FTP program like CX-explorer, you can drag the files off the tablet, follow the script in the youtube video about modifying the .trc files and changing the checksum, and then drag it back via FTP to the tablet, and use Pro-tool to push the .trc file to the module.
The FTP portion also makes it easier when Im dragging logs from my tablet and uploading to datazap or something.
