Hi everyone,

I am stuck, trying to understand the wiring.

I have 07 march build 335xi, steering came with no paddle shifters. I purchased an LCI steering wheel with paddle shifters.

While following DIY I noticed that my steering wheel is already wired for paddles and black connector does not have any missing ports. All I had left to do, is tap wires into the connector behind steering column and tap those same wires into center console shifter lever. What i have noticed is that the connector behind the slip ring ALSO didn't have any missing wires, my though is that it was already wired from the factory. So in conclusion all connectors were full of wires and there were no sports to tap wires into. Shifters don't work, however multimedia buttons do work. My understanding is that there is something to do with wiring in between sleep ring connector and shifter that I DID NOT do. However like mention, no empty spots were on the connector from slip ring.

If that makes any sense, please explain me what I did wrong and should I still tap wires to connector that already has wires in place ?

I'm assuming you're using LCI paddles (left side only downshifts and right side only upshifts?). If so, you likely need to remove the resistors inside the paddles. You may also have to rewire the plug from the paddles.

I' have read through that post entirely, thanks for info. However most people were retrofitting prelci shifters to LCI shifters. My car on the other hand has no shifters at all. I am thinking that the car is not programmed to have paddles, plus the oem wiring is incorrect as well. I can try removing resistors and shorting, but as I understand that gets rid of 3 way connection for PRE LCI models that have shifters +-. In my case even if I remove resistors and short connections it might not understand that I have paddles at all. My question would be, is there coding required to go from non paddles to any kind of paddles ?

You don't need to code paddles, and that thread applicable to those who didn't have paddles to begin with.

I installed LCI paddles on my 2006 325i (which didn't even have a sports wheel or paddles to begin with). I still had to rewire and remove the resistor to get the paddles to register.

Thanks you again for the info. I will go ahead and try to figure out that resistor magic. Did you have to tap wires into connector behind slip ring to the shifter, or was yours also oem wired ?

I had to use a harness since mine wasn't prewired, I think I used motivemods retrofit harness.

Paddles will not work unless you have the correct multifunction buttons from a sport steering wheel, did you reuse your original buttons?

[Whinodez]

You also need a retrofit harness like the one from burgertuning, you could make one yourself if you look up a diy

I don't know if you are trying to be mister obvious or just trying to help me. Read above. DIY has been read, problem is: wiring in DIY is non existant, and my wiring is done from factory. Also why would multi-function buttons be a problem when they work just fine.......

[Whinodez]

Whatever wiring you think you have will not operate paddle shifters, there is no empty plug, the retrofit harness piggybacks into the steering column wiring. Just because your buttons work dosnt mean they will operate paddles. If you want the correct part so you can verify yours I can send it when I get home tomorrow. Trying to helpful but if you want paddles that never work, don't listen..........

multi-function buttons on non-paddle shift cars do not have any electrical contacts in the sockets that receive the plugs from the paddles. Ridiculous but true. You can plug the paddles in, but they won't be electrically connected to anything.

You need to either source the multi-function buttons that have the electrical contacts inside those sockets (easy to see if you look) or you need to wire the paddles directly into the plug that connects to the steering column.

[gavronm]

If you're saying that inside your steering column you have the yellow/black and yellow/white wires shown in some of the DIYs, you will also need to splice into those wires and connect them to the blue plug under your shift lever, as shown in the DIY.

The yellow/black and yellow/white wires, which I didn't think were usually present on your car, but you say they are there, run to the junction box behind the glove compartment, and in non-paddle shift cars they dead-end there. In paddle-shift equipped cars there are additional wires coming out of the junction box that connect the yellow/black and yellow/white wires to the transmission controller.

For your purposes, you need to modify the LCI paddles so they are switched based (i.e., remove and jump the appropriate resistors) and then directly wire them, in whatever way you choose, to blue connector beneath the shift lever.

Once you do that, when you pull a paddle the car will think you've used the shifter to initiate a manual shift. It's not the way the OEM system on a paddle-shifter equipped car works, but it works nonetheless.

I am still not understanding the Multi-function button issue here. I don't think they are related to paddles. Issue is from slipring to shifter connection.

Thanks for the info, it gives me more clue about wires that are OEM fitted into the slip ring. You are saying that these yellow/black and yellow/white wires are dead end in glove-box compartment, as I understand the wiring still has to be tapped from slip-ring to shifter to actually make a physical connection.

After that, I may have issues with the resistors as I saw earlier. Need to remove 2 and short one on each side of paddle

Read gavronm's post above, the paddles work through the multi function buttons, wrong buttons and paddles won't work.

After driving today and shifting with M, after parking my car a gear on the dash appeared. CC ID 347 Shifting R/N/D not possible. There is only 1 post about it, and its a solenoid "C" problem with cost 600$?! what the hell did i do ?

you got this resolved?

[Dominasian335]

Yes I have, I missed a white connector under the shifter. Now I can shift no problems, except paddles still an issue.

[Wanas]

Hi guys, when you retrofitted your nonpaddles cars to lci paddles, can you shift with them on D or only on DS?

Did you ever get this figured out? I'm in the exact same situation as you.

[Jonathane]

If you are using LCI paddles you need to code GKE11T module using NCSDummy & NCSEXPERT for the below in order for your LCI paddles to work:

NIC -> change from nicht_aktiv (not enabled) to aktiv (enabled)

EL_INTERLOCK - ELECTRIC INTERLOCK -> change from nicht_aktiv (not enabled) to aktiv (enabled)

PADDLES - SHIFT PADDLES TYPE [WERT_00: SWITCH-BASED WITH STEPTRONIC, WERT_01: RESISTANCE:BASED WITHOUT STEPTRONIC, WERT_02: RESISTANCE-BASED WITH STEPTRONIC] -> wert_02 - value 02
