2004 E53 Project!!

[axgordon]

When I took my 05 4.4 to the friend at the dealership for EGS update, I was told that on 04-06 cars with N62 / ZF6HP-26 cars, you can’t update EGS separately from DME. Therefore, after the update, I got both DME and EGS on the latest version. Took about 35 minutes for update program to complete.

Good day!

I replied to this early this morning, but it didn't get posted for some reason. No worries tho! So, when I got this info, I was completely excited that I would get to drive the X to work tonight (I'm on night shift)... I hooked up the laptop to the X and started everything up. Hooked up the 540i to the X and let the 540i idle... it worked last time when I updated the trans computer (VGSG83), so it should prove sufficient this time too... I pulled up the data in INPA and everything looked good... I opened WinKFP and had to search for the correct module... It doesn't say DME, but instead it was 19EK9284 or something like that... I pulled up the READ UIF and it had the matching info INPA had... HOWEVER, I couldn't find my assembly number in the list and had forgotten how to update to the new one letting the software do the picking... it got late, so I had to pack up in favor of getting some sleep for work! I'm going to start over tomorrow again, but this time I have the procedure... I really hope this works! Really really!

Thanks so much for this valuable info! I do have to ask, are you positive your buddy said the engine processor needed to be updated to filter down to the transmission EGS? I was told to do the trans processor, which I did, but obviously didn't work!

Anyway, I'll let you all know how it goes tomorrow!

Cheers!

I am 100% positive that DME and EGS had to be updated together on e53 with n62 engines. The computer system that dealer used at that time didn't allowed for the separate EGS update. I can't say with the same certainty that WinKFP works the same way, but I was there when he set this job up and BMW service computer only allowed for the combine DME/EGS update. I have no experience updating n62 with WinKFP. I used it successfully on 540i with m62tu engine.

Hey axgordon, I noticed in your signature you had the servotronic retrofitted. I looked all over online there were no guides or anything. Would you happen to have any insight on it? Mine is an 06 4.4 non servo sport model.

I read one of your posts and it seems pretty simple. So basically all we would is a servotronic steering rack and the servotronic motor? And the after do the coding procedure to add that option to the car? If you could shed some light on this it would be great as I really wanna do this.

So here's the parts list I came up with :

For vehicles with
HYDRO STEERING-SERVOTRONIC
S216A=Yes
01 Rmfd hydro steering gear Servotronic ZF 1 10/2003
32136769268 $2020.75

And motor

For vehicles with
HYDRO STEERING-SERVOTRONIC
S216A=Yes
07 Torque converter servotronic ZF 1
32106788212

So if you could just confirm that that's all we would need that would be great. And oh also you said that it might be prewired, there's a connector by the left strut tower or something I believe?
And finally for the coding part what did you use, I have BMW scanner 1.4.0 but I'm unsure wether it could do the job or not.
Thanks in advance.

To answer your questions:
1. I can’t guarantee, but every e53 that I look at comes pre-wired for “Servotronic” .The plug is wire tied to the left strut tower.
2. I coded GM3 module with NcsExpert. Enable option 216A. I am not sure how to do it with your scanner, but I think it is possible. Use same technique as with most other modules.
3. Please note that I did not modify vehicle order file – it means that if car is coded with the data associated with your VIN – You will have to code Servotronic again. So, if you are planning to code other modules on your car with tool such as “Progman” - remember to recode GM3 to re-enable Servotronic. Alternatively, do it right the first time and update vehicle order information. In my case, I did not bother. If you do not plan to code the entire car with the “Progman” tool, than it is no issue.
4. I used “A1 Cardone” rebuilt racks and ZF servotronic converter valves on both cars. Looks like FCPeuro offers ZF rebuilt rack with converter attached – just verify with them to be sure. https://www.fcpeuro.com/products/bmw...x5-32136769268
5. If you choose, aftermarket rebuilds option – those come without converter. You can get it here: https://www.fcpeuro.com/products/bmw...em-32106767408
6. The Cardone rack which I use on both cars - Part Number: 26-2818. No issues for over 60k miles, but I think ZF is the better route, especially if it comes with valve pre-installed.

Good day all!

This servotronic stuff is interesting! Maybe that will be next in my list... Well, I'm currently at 70% of the programming... Started at 17:21 (5:21pm) and it's now 17:58 at 74%... I'm being particular to not let my computer do anything except program... I'm even moving the mouse every minute or so, just so it doesn't plan to start my screen saver... Overboard maybe, but this project needs a positive outcome soon! Like one that means I can use the X!

Okay, I'll keep yous posted on the outcome!

Cheers for now! (81%.......)

Well, Murphy is alive and well! I know how important it is to get the VIN correct! I always verify it's right! I don't know how I manged to miss it this time, but I fat fingered one number! AND I don't have fat fingers at all! So, I get to do it all over again to keep my X from being a huge paper weight! Another hour to wait...

UGH! WHOOSA!

Cheers!

[williamx5]

Well, everything still works and I lost one slot in my programming limit due to the VIN error... I still have nine left, so I guess it is okay... Both programs took (the error and then corrected one)...

HOWEVER, the EGS did not get updated and I am still in NON-SPORT mode for the transmission, getting the failsafe right away...

So, my next idea is to plug the mechatronic into the vehicle and copy all the settings from it... Then code the new one with those settings... IF that doesn't work, I'm getting the ICOM set-up and go from there...

Sooooo, that is where I'm at thus far... I'll let yous know!!!

Cheers!!!

Wow thumbs up man with all that computer coding stuff. I wish I had some insight on it but I'm clueless. I do however have a friend that's a master Bmw mechanic that may or may not have experience with this coding stuff. So tell me a little about what happened previously so I can tell him and hopefully he can give us a diagnosis. Cheers.
