Ok, where's best to get a cable? I see bmcables have some bad reviews etc.

"D-Can Diagnostic Package" from

http://www.cable-shack.co.uk/products.php

I am sure the cable itself can be purchased much more cheaply but I know this one works and it comes with a DVD with all the software.

Happy to code it for you if you're passing through West/South Yorks at any point also.

Cheers,

I know a chap locally who is a bmw & coding expert, so i may ask him to take a look see for me.

I've just bought a set of heated leather seats to replace the cloth ones. I wouldn't have a clue where to start with all the wiring and coding though! Is there any chance you could do mine? Obviously I'd pay you.

Coding was straightforward. Using Default profile in NCSExpert load VO from CAS or NFRM, add $494 to VO, write VO to CAS and NFRM, code JBBF and IHK.

I managed to code $494 to the VO in my CAS and NFRM, but which options do you need to change in the JBBF and IHK ? this the bit i'm not sure about.

 

[Jack79]

I think that you do not change anything, just sg_codiren witout option "manipulate by MAN file". JBBF and IHK just have to know that something is change in car. This will enable everything that should be, to heating work.

 

[sp33dy]

Ok, maybe I have missed that step or something, I'm a newb on this coding business. I have only followed the change VO method in ncs expert so far, still learning.

Yep that's right. After changing VO, SG_CODIERIEN on JBBF and IHK just forces them to update their coding to reflect the new VO. Make sure you use a profile without manipulation, on my install it's the "Default" profile.

Where are you located? I don't have enough spare time these days to do the whole job but I can help with coding and checking wiring (free/for beer).
If you print out this thread and take it to any independent BMW specialist they should be able to do the job also.

After you load the updated VO from either CAS or NFRM, go back until you see the option to "Process ECU", select JBBF, change job to SG_CODIERIEN and run job. Do the same for the IHK. Don't select "Process Car", this codes the whole car unnecessarily.

 

[sp33dy]

Ok I didn't do SG_CODIERIEN, I just did fa_write only and yes on default profile too.

I'm base in the northeast but wouldn't mind driving down. I might attempt it myself when I get a bit more time to sit down and read through this properly. Need to get my B12 kit on first followed by cruise control retrofit.
If I get stuck I'll drop you a line when I get round to it if that's ok

 

[sp33dy]

I'm going to try this again later, as ncs was only giving me the option to code all of the ecus. The select ecu button changes to process as soon as I go back.

The car still has $494 in the cas, nfrm.

Then at this point the low battery warning came on. So I'm going to pop her on charge for a bit firstly.

Cheers guys.

 

[sp33dy]

All sorted many thanks guys.

I did a read of the (2)JBBF and the IHK before and after, this is what changed in the JBBF, (nothing changed on the read of the IHK): -

Nice one. All working then?

Yep, I'm impressed how quickly they warm up too.

That leaves just the door cards to fit next.

Oh and it looks like my battery is on its way out too. So I might have to do that next. I keep getting the battery symbol (and a few codes about this)

Once again thanks for the help, and like i said before your write up should become a "how too"

Do i did retrofit manual sport seats with heating. Bolsters work, heating works. I get one airbag error 0093C1 which means seat occupancy sensor passenger side. I just wonder if this has something to do with one wire which i left not connected. It has two pins and brown yellow wire. see socket on the picture. This cable comes out of the rail somehow and i didn't know what to do with it. any ideas where it goes? there is no place for it in big yellow plug....

Ot should be one wire due to diagram purple and red.

You can see where the plug are. These are links to next pages.

That retrofit wiring set is a bit more than I was hoping (£80). It includes the underseat looms (from seat connector to heating module) as well as the seat to JBBF looms. If you get a complete set of heated seats you won't need the underseat looms.

Here's the part list to make up the seat to JBBF looms:

4x 61 13 8 364 844 Socket contact ELO-Power 5,2x0,63 (Seat connectors X275 & X279)
4x 61 13 1 383 776 Jack MQS (Seat connectors X275 & X279)
2x 61 13 1 388 431 Cable terminal (Grounds X490 & X173)
2x 61 13 0 005 197 Bushing contact (JBBF connector X14270)
2x 61 13 0 007 438 Double leaf spring contact (Fuse holders X11008 & X11001)
1x 61 13 1 378 906 Double leaf spring contact (Fuse holder X11001)

All the fuses are the "mini" type. Fuse locations may vary, this info is valid for a facelift 130i with manual seats.

Now that you have it complete would you recommend just buying the retrofit harness or building with the parts list above?

 

[mrtoast]

Yep definitely make them yourself if you can solder & heatshrink.

 

[Dengaman]

Nice find that TIS site, just been reading the seats section, and it seems to say "must use new fixing bolts" to put them back in ????

Hmm, yeah I see that too. I reused mine, I don't think they are stretch bolts but they look to have had some kind of threadlock on them.
I guess as a safety-critical part they are extra cautious. Think it will be fine to keep an eye out for them loosening or you could put more threadlock on I suppose.

Finished making up the wires:

I got the parts part, so i can make the looms myself, but i'm missing the length you used... Without that is is ordering in the dark

Sorry, I don't remember. You can get an idea by measuring from the seats to back of the footwell and to the fuse box.
Make sure to leave enough slack for the seat to move and to route the wires down the side of the footwell.
