Something interesting I've found here: http://www.e90post.com/forums/showth...=361439&page=6

As I read through this thread, I couldn't find a confirmation that the proper wiring exist: even if the slip ring had the proper pins, the wiring behind it may be missing.

Here's a couple of pictures.

This is a E90 without paddle shifter:


And here's the same connector for cars with paddle shifter


You'll notice the paddle shifter wiring has a yellow-black and a yellow-white wire.

I thought I point this out before spending too much time over coding which wouldn't lead anywhere if the proper wiring is missing.

Now it could be that in the LCI they standardized the wiring (maybe to accomodate the wiring required for the ///M which as far as I know was the only X5 with paddle shifter, but I could very well be wrong) or something so they are always present, while in the per-LCI there was no need. In addtion the 35d didn't see any change between pre-LCI and LCI (other than cosmetic): it has always had the same engine and transmission, so maybe for that one the wiring never change

The fact that the slip ring has the proper pin-out is a good thing.

The yellow-black and yellow-white apparently go to the Gearbox module. More information here (read the comments to the video):

And now let's talk about the mysterious X6031 connector mentioned in the YouTube video.

You can find it in the electric box on the passenger side under:



The pin out looks like this:



I'm also attaching the wiring diagram and I apologize if the writing is so small, but I can't figure out how to PDF it in a readable fashion. Just bump up the zoom to 400%.

In our cars pin 3 and pin 9 are not used. If look at the diagram too you'll notice that A7000a is the transmission control and S227a is the gear selector switch.

It is unclear for the wiring diagram whether pin 3 and 9 of the X6031 have no wire only one side or both.

I hope this helps you guys and I'm really looking forward to see if anyone can go somewhere with this.

So here's what the story may be...

The X5 has a fully electronic gear selector and a "Gear Selector Module" (same as the E65 7 series according to BMW literature: the E65 had it mounted in the steering column while we have a lever) and there's only one wire going from the gear selector to the transmission control module (I think it's a LIN-Bus signal). You see this in the attachment called "X5 E70 - Gear Selector". I guess when you put the transmission in "M" and up or downshift the gear selector module process the action internally and sends a processed signal to the transmission module.

If you look at the E60 diagram, you'll notice that that EGS up/down signal are not processed by the gear selector module, but sent directly to the transmission control module through pin 3 and 4 of the X6031. You also see that the version with paddle shifter injects the shifting signal into the same pins.

Long story short: if the wiring from the X6031 to the transmission is the same as the other car, it now makes sense to connect pin 3 and 4 (or whatever the pins are) to the paddle sifters: you're basically wiring it the same as the E60 is wired.

As said you'll have to code the transmission control module to process that signal that it know received directly...

Since it makes sense that the signal is a resistance and not a voltage (I'm saying this because I think a voltage signal would require 3 wires as opposed to 2, but again, don't quote me here) then it's irrelevant which way you connect the pins from behind the slip ring to the X6031.

Looking forward for feedback from someone who can verify this and then I'll pull the trigger on the steering wheel...

Looks like the X6031 connector route may not be the right one: I quickly looked at mine and there is no pin 3 and 9 as expected, but it's not there on both side so just wiring from the slip ring to the X6031 won't work. You may have to go all the way yo the transmission.

Here's a picture:



I'll try to reach out to the guy from the YouTube video and try to get clarification....

Right now the only thing I can think of is having to wire it all the way to the transmission: pin 4 and 5 in the mechatronic are the pin used to control + / - signals.

It's a diesel, 2009 35d, US version... If you kook at the tach on the video os a diesel too, albeit EU.

What could help is the wiring diagram of an X6 since the earlier version had the ZF 6HP, electronic shifter using LIN-Bus to communicate to the transmission and paddle shift. If I can find the diagram it may confirm that the paddle send the signal directly to pin 4 and 5 of the mechatronic: those are the 2 pins in the 6HP where the shift signal is sent to in all the diagrams I've looked at...

This is getting so frustrating. We seem to be getting close, but we are still so far.

Kakalika, did you see if your connector had the female connection portion on the X6031? I havent been able to check, after i get off work everyday its dark outside.....

Sorry for the blurry pic.

Bad news, my 2012 also does not have the female portion on pin 4 and 9 on the x6031 connector......

Zetatre, hope you have more info!

Quick update.

I was able to find the pin layout of the connector X1880 which is the one behind the slip ring. Two pins (#2 and #4) are reserved to the paddle shift.




As you see both are indicated as "No signal processing in the control unit" which I interpreted as not used. As a matter of fact I checked and in my car and both pins are empty. This basically means that without some wiring the paddle shift will not work.

It may be hard to see but if you look careful you'll see pin #2 and pin #4 are empty:



I've also removed the connector X8532 that goes into the transmission mechatronic (identified as A7000a). As I said before our car sends a processed signal from the electronic Gear Selector Switch (S277a) to the A7000a through LIN-Bus connection on pin #8.

In other cars where the gear selector is a simple series of switches the signal for shift up/down (both from the gear selector itself and paddle shift) is sent through pin #4 and #5 respectively.

As expected in our car pins #4 and #5 are empty. Here's a picture of our X8532.



I'm still looking for the wiring diagram of an X6 with the ZF-6HP: hopefully that provides some additional clarity, but all I can say this far is that paddle shift on a X5 35d diesel won't work without some wiring...

its like BMW really doesnt want us to have paddle shifters on this car.....

found a interesting site, but i cannot get the pdf links to work......even after i registered

I am not sure if it has already been mentioned but to me the OP's steering wheel is an actual ///M wheel while the one you got is a M-sport wheel. ( Hence the non tri-color stitching )
Again, I am not sure it makes any difference or not.

right now it doesnt matter what wheel, so far us diesels don't even have the wiring for the paddles and it seems like some of the LCI 3.5 with sports package may have it preinstalled. all luck of the draw. OP had a LCI 3.5 with sports package and it was plug and play.

Ok, I finally got confirmation of my suspicion in a discussion over on another board where I met some familiar faces.

Another member confirmed that wiring is required from the slip ring to the mechatronic. In particular you need to wire from the slip ring connector X1880 to the mechatronic connector X8532. The upshift signal goes from pin #2 in X1880 to pin #5 in X8532; the downshift signal goes from pin #4 of X1880 to pin #4 in X8532.

If the paddle shift are switch based the "simple" wiring should be enough to have them working; if they are resistance based (and I think the +/- style are) you either try to add $2XA to the VO and change the EGS parameter "PADDLE" to wert_02; or you hack the paddle open, remove the resistor and convert it into a simple switch...

Now the question remains for: where do I get the connectors... Your local dealer can help.

Here's a bunch of circular ones for the X8532, you're probably looking at either of the #7: http://www.realoem.com/bmw/showparts...96&hg=61&fg=15

And here's the pins for the X1880 I'd guess #1: http://www.realoem.com/bmw/showparts...91&hg=61&fg=15

There's a couple of sizes so someone needs to figure out which one is the correct.

I really really really look forward for someone getting back to me and say we solved it!!!

Hi there. Wonder if some of you can help me with one question about steering wheel.
I have an european 2011 lci 3.0d with 8 speed auto.I have a sport steering wheel without heating,and was wondering if i installed a m-sport steering wheel with heating if it will work?
I`m not so good in english, but the question is will steering wheel heating work when my last steering wheel did not have that option?

zetatre, where is this X8532 connector? can you post some pics to where and how to get to it?

That's the round connector that goes in the back of the transmission. If you crawl under the car and look for it it's hard to miss...
