I have the standard Hi Fi.

 

How can I tell if e90 or e82 has this button? Where do the wires go from the DSC button? - because my DSC button looks different on the back

 

Nah, I need to change the two O2 sensors (pre-cat) .

 

Does the car need to be programmed 100% after buttons installed? bit of mix on feedback

I fitted the button yd and bar the 'sport' lighting up...not convinced its doing anything. I'm already remapped so maybe why don't nottice as much and only had a very short run so yet to to trial properly. On a pre lci 04 530d seAuto if makes a diff like

 

I got all the stuffs ready and I have a question on wiring.

I got LED momentary switch as attached picture and I really want to avoid frying the module.

Can someone draw a line for dummy which line goes to where?
I am quite smart in making question though…

I watched ROSKINC’s youtube video and also learned from this thread that #10 is positive and #8 is negative.. and that's all I know

The way I want to set up switch is, leave the LED light off when sport mode is disengaged and on when sport mode is engaged.

Thanks

 

I think BMW does this to save time, time is money for them, you know.

 

8 -> C
9 -> (+)
10 -> NO
ground wire -> (-)

 

I appreciate your input.
I will give this a try over this weekend.

 

is it that simple in the LCI?? i cant get to know where those cables are!! and to be honest i'm not taking my chances!!!!

 

Guys I found the unit in my LCI behind the glovebox, the thing is, it's way different than the one in the picture! :S mine is like twice the size and all wires are already there!
I removed the wires 7&9 anyways... And connected my own, and took the car for a spin,,, still! Nothin! I know it doesn't appear in the cluster,, but I couldn't feel any difference!what should I do?!
