Okay!!! I can do that!!

It all started when I was looking for an update to my Durango... Intro to my new 2004 X5 4.4L with lots of options... Oh, maybe not that far back in history... Apologies...

Well, after I rebuild the motor and had it running in the X, I decided to take it for an initial test drive... As soon as all the fluids got up to normal temp, the trans faulted out and would not indicate what position the shifter was in... I did the research and it pointed to the EGS module on the Mechatronics (valvebody)... I figured out it faulted out at around 112 dec C using INPA... Figured it was the lifetime fluid hitting the END of it's lifetime... I changed the fluid, filter, and the recommended seals... It did not fix it... So, I bought a 2006 trans... Since it was cheaper to get the whole thing in favor of buying just the mechatronics... Just as my luck would have it, the 2006 was NOT a "Sport" model... So, now the trans faults out upon initial start up... There isn't a line in NCS Expert that I can toggle to "Sport" mode... All the entries in the module are "wertz 18" or some odd number with a meaning only the guy in the basement of the BMW R&D lab knows...

So, in short, if I can turn on "Sport" mode in the Mechatronics, the VIN being different really doesn't matter to me... If I can program or code the EGS to work with my VIN, I'll go with that too!!! I'm close to installing the original Mechatronics and put some extreme trans fluid cooler on it... Just to see if that would keep the original from faulting out...

This is the long version of the short story...

Thanks so very much for your time!!

Cheers!!!

I'm always surprisingly puzzled at how little (or not at all) the BMW techs at the dealerships I've dealt with know about the software tools we (DIY community) know about and use - INPA, NCSExpert etc. They seem to only know ISTA, DIS - the regular official dealer software. But all that factory level software we're using....nada. Or may be they just pretend not to know about them because these are all "illegal" software not meant for the public....:dunno:

Most probably don't care. They aren't enthusiasts, being a mechanic is their job and they just happen to work on BMWs.

Hey William, I haven't forgotten about you but I haven't been able to get in touch with him looks like he's outta town. Any progress on the X?

Good day Yaz!

Na... Nothing major the past couple days... I did hook up the original Mechatronic to the connector and copied all the module settings in NCS Expert... I think I will do the same with the new Mechatronics connected up to see if there are any differences... Time consuming and such, but it is a "safe" way for me to verify if and what is changing...

Heck, it is getting colder out... I might be able to put the original back in and have it work just fine until it starts to heat up outside next spring... I may consider that as well in the near future if all else fails...

I would love to know if there is a way to "load" the entire car with the "factory settings" in one swift wave of my magic wand... Is that what "Process car" does?

But, that is where I am right now... Work has gotten the way of progress... Stupid job!!

So, no rush... Take your time and I really appreciate all the help!!

Cheers!!

Cool cool sounds good, hopefully it's all sorted out soon. I'll update you as soon as I hear something from him. And I picked up and 06 4.4 this weekend of my own. The whole dash was lit up like a Christmas tree service engine, abs trifecta, tire pressure, everything except for he has light half a tank lol. Cleared everything and now I just have to sort out the 2 axle air suspension issue and possibly a smoke issue, smoke from only right side… anyways, I'll start a journal or something to document everything when I get home today with pics and all.

Cheers man

What if you swap the old mechatronics into the new transmission.?

The computer chip part of the mechatronics is the issue... The hard parts of the original trans are still going strong...

Cheers!!

Good day all!!

Well, I hooked up the original EGS unit and pulled all the "coding info" from every module... I saved the readings from each module to compare with the readings from the module with the NEWer EGS unit... After reading every module with the newer EGS module, there were NO differences... NONE!!! This issue is not a coding issue at all!! I have to get into the EGS module and program it directly or thru the ECM using different software than I have now... So, I guess I will be on the lookout for a good used ICOM set-up...

That is it for now...

Cheers all!!!

Good day Yaz!!

If you get in touch with your friend, do me a favor and find out what software and hardware set-up he is using... I think I have hit the limits of the WinKFP and NCS Expert software in trying to code the EGS in the transmission... What I have isn't talking to the module thru the OBD port...

Thanks much!!

Cheers!!
