Multifunction DIY

Anyone have a permanent host for one file that is about 470KB big? I want to help people out in the community with the DIY for the multifunction retrofit. I get about 6 or 7 emails monthly for this. I am tired of having to follow up with emails and people that ask me to email them the instructions and then the email comes back to me. So if this could be hosted on the board that would be so much easier.

That woudl be good. I have the PDF files that show all the instructions to do this. Its not that I don't want to help people out its just that it would be so much easier if it were permanently on this website so people didn't have to contact me for it. The instructions really just tell you how to do it but there is a substitute for the wiring harness.

Hi,

I'm hosting a DIY for Technic for the NAV retrofit on my server and badged it all under a DIY page for Tourings and all E46s.

Check out: http://stradasystems.com/bmw/

If that home suits you, and you can definitely deep-link, then send me the file.

The part # in the pdf is for the entire retrofit kit (including steering wheel). Went to the dealer to find that wiring harness and he couldn't find it. Basically said he'd have to order the entire kit to see the p/n for the harness.

Well in order to make your own harness looking at the 2 step in the pdf that shows the MFL/GRA Wiring diagram all you need to make is three wires

A1 - A6
A2 - A5
A3 - A4

All you need is some wires in about 3 feet in length for

A2 - A5 and
A3 - A4 and for A1 - A6 I would make it at least 4 feet maybe a little bit longer because it has to reach to the DME/ECU through the firewall.

For the socket contacts just go back to BMW or order them I forget the part number but you can't just buy the socket contacts themselves you need to buy the actually little wire thing whatever it's called. If you already have the multifunction steering wheel you can see underneath it what I'm talking about. I will post a picture later. The part only goes for about $10 - $15
and all you need from that wire set is 4 socket contacts.

Don't worry about A4 and A5 you dont need to use the connectors it shows in the diagram. Instead when you get to A4 and A5 and have to cut the wires in the LCM wiring harness just use butt connecters they worked fine for me.

Wow 4 links to the retrofit now!! Anyways the part I was refering to above to use the pin socket contacts from for making your own wiring harness: The part #'s are as follows:

61318375435
or
61318372918

you can use either one all you need are 4 socket pins and both parts come with 8 so pick the cheapest one.

Such a Great Link BMW ETK Online

First post, so don't butcher me..

I tried searching for the Multifunction retrofit for a 328ci '99, but couldn't find it anywhere. It all seems to be for car's from 6/'00 on. This car doesn't have the "new" 3-spoke sport-steeringwheel with the one split spoke, but the old 3-spoke sport-steeringwheel. So, the question is, is it possible to retrofit the multifunction on this one?

Yep, I retrofitted m3 steering wheel on such a car. Basically it's just about connecting 3 wires. I have old version of that pdf, which mentions '99 models. Can't put it online now though, but I can email it tou you - PM me your email.

Per pdf file "bmw 3 series coupe, touring, saloon, covertible and comptact from start of the series also for all E46 4-cylinder models with new generation engine N42, LHD/RHD". So if you have such engine then it's possible.

Hi Guy's

Reviving this thread with a question.

So I did the MF DIY also,ordered the wiring harness and everything went great +all functions work nicely exept now my airbag light is on.

Does the computer has to be reset to make it go away?
Already made an appointment for programming the OBC (did that one as well => steering wheel was of anyway) so they can do this at the same time.
But if this is not the case,I'll have to search for what I did wrong or broke.

@freshslo : on a petrol engine you need an additional actuator to regulate the gasvalve,I just needed to plug in a wire in the main wiring harness and voila (diesel engine )

Thx C
