General Module GM3 upgrade
 

My auto steering wheel makes me mad (I mean auto tilting during each ignition on/off). As far as I know it is possible to disable this function by coding in NCS Expert using EINSTIEGSHILFE_HOEHE and EINSTIEGSHILFE_LAENGE options, am I right? And am I right that these options are available only in facelifted E53's?
If so is it possible to upgrade GM3 module in pre-facelift X5 to the module from facelifted car? I'm aware that for sure ncs expert coding will be necessary but are these modules compatible with each other or maybe this kind of upgrade is not possible at all?

I'd like to disable it as well will be interesting to see if anyone can shed light on this subject.

Just check the part numbers of the GM of the facelifted with the prefacelifted. If the numbers differ then more than likely they are different. I would be surprised if the modules between the two series are the same since different engines and transmissions were used between them.

Yes, part numbers are different and there are differences in hardware, that's why I'm asking if it's possible to swap them :)
Engine and tranny have nothing to do with GM I guess.

Yeah but your talking about two different series of X5 E53s. There were a lot of changes between the pre facelifted and facelift X5s. For example charging modules on the these vehicles are different. You are going to want to use a GM for that year vehicle and features.

I have a pre-facelift without the auto tilting. Are you sure it can't be disabled?

The prefacelift has the auto tilt as well. My 2003 does it

If I am not wrong it's called Comfort Access and it's an option you can disable in PA Soft 1.4.

Looks like new modules can be coded for any year.

Thoughts??

New modules are backwards compatible.

If you save it to seat memory, would it stop moving? Or is it programmed to move up and way anytime any driver gets in and out?

When you turn off ignition the steering wheel rises to highest position so it's easier to get out and back in. So a built in feature. As a default on E53 the up/down movement for easy entry is set active but the in/out movement not active.

Ditto my 2002 4.4. Works currently, but has been inop in the past. Specifically for the time the seat controller was broken. Once I replaced that with an ebay unit the up/down as well as in/out started working again.

As does my 2001...sometimes, whenever it feels like it.

For the last few months, my steering wheel and drivers's seat will move around as I unlock the truck with my remote, but never move as I get out. Though I re-programmed the seat buttons several times, it still hunts for position for a few seconds. However, since I'm the sole driver, the wheel and the seat always are in my favored position before I sit down. ??? Doesn't matter if I use my original diamond key remote (with chip), or my E-bay key (without chip inside).

Another thing: the passenger-side mirror sometimes dips when backing, then resumes its' normal position going forward, but at other times, the resumed position is way-off. So, lately, I've disabled the mirror dip, so I don't have to reposition the mirror while driving...not a big deal.

Tried coding it to the case but ncs expert gives an error.
I read zcs from cluster and then tried coding the new module, no luck. Has some kind of protection

Could you give a bit more specs. What error does NCS give you? Did you try to write VIN on it first?

Clavurion I ended up burning my rear hatch lock because of the wrong GM.
Now I'm scared to try again lol.
I was trying to code GM5 for E53 2002, instead of GM3.
As you said it's backwards compatible.
I may give it another shot and see what error I get.

So you tried to install GM5 from E46 or E83?

Sorry no, my bad, it's actually GM3.
It's the exact unit from my post #9.
I was thinking GM5 because they have similar outer cover, but it's actually GM3.
GM5 has different connectors, and I wouldn't be able to do that with GM5.
I'll try again and post the error message.

Tried connecting it again, and 4 way flashers were flashing, could not turn them off. Reconnected one more time, and seems fine, hazard lights were off.
Also heard a click from my trunk. I don't know if this module is coded differently, or these GM3 modules without fins come from facelift version.
But thats how I burned my trunk actuator last time.
The top portion would not open, but when I pressed the button to open it, the bottom tailgate would open.
But since the top lid wouldn't open, I couldn't open the trunk before pulling the manual plastic string.

Ok tried coding the module from post #9, this is the error I'm getting.

Strangely, these two modules coded without errors.

But there's definitely something wrong now.
After I code these modules, the central locking, for example doesn't work. The rear hatch button doesn't work, neither on the hatch, the center console button or the key. Who knows what else doesn't work.
I suspect it's been burned again by me connecting these newer modules.
When I reconnect the old module with the fins, the central locking works.
And when I press the rear hatch button with the old GM3 module in, I at least hear a clicking inside the GM, so I know it's sending the signal, but the rear hatch actuator probably burned again.

What gives?

Maybe because you’re trying to fit a GM3 w/sca to a car that doesn’t have sca. Facelift X5 had soft close access on the rear bootlid. You need a GM3 wo/sca.

I think this is the latest version for a pre-facelift: https://www.bmwgm5.com/Images/GM3/GM3_6940923.htm

Ahhh that makes total sense, thank you!
I guess it's a warning to others, don't install the newer version or your trunk lid actuator will burn, like mine did twice!

This is good to know. I didn't even realise pre-facelift didn't have soft close feature. It seems the bootlid lock wiring is completely different on these models and there are no coding options to facilitate so they are different module specs.

I put a used GM3 in my 2003 4.6is to alleviate the Power Steering issue I was having (not engaging). Purchased from Ebay and installed, no issues since (2 years ago).

They're both GM3.
But I'm curious did you put the one with or without softclose? The one on the bottom or the top of the picture in post #22?

I'm wondering if there's a way to tell which newer modules have the soft close option and which do not?
Maybe just need to figure out the date this option was introduced. I didn't even know what facelifted E53 had soft close option!

This is a trick question, right? :confused:

Or have I misunderstood the question and the text on the module that says "E53 W/SCA" is a red herring? :bustingup

So does my 2001.

I don't mind it, but it's one more thing to fail eventually.

Hahaha brain fog! You the man!
