So i got everything wired up fa write cas and frm, vo coded cic dsc kombi but ldm doesn't want to take the vo code

unrulyteach · 08-02-2019, 01:45 PM

I'm not sure if I'm not getting power or it's coding or it's not waking up the modules.

Do you have 15 wake up and the can wires installed properly? Did you repin the ACC end of the VW harness?

Yes 15 wake in pin to number 18 can lines tapped to 43 44 of frm cause i hav AHL hav power going to fuse 64

unrulyteach · 08-02-2019, 04:12 PM

I will see if I'm getting power later. In ista i can call up ecu functions of ldm but not acc

unrulyteach · 08-02-2019, 09:33 PM

Ok i figured it out my add a fuse was in the wrong slot so now i need to adjust it

unrulyteach · 08-03-2019, 01:39 AM

I finally did it

Funny thing is i aligned it last night and this morning when i was going somewhere it was work but then all of a sudden it got missed align. Bummer so ima take it to my Indy hav him align it properly

unrulyteach · 08-08-2019, 11:28 PM

Does the acc sensor need mirror for it to be properly aligned?

Most indy's will not be able to align the sensor.

Thanks for this DIY, now i Will build in my car to !

Ik for a fact one is new while one i bought off internet cause i needed the stalk but it looks fairly new

Huge thanks and applause to Nickco43 for doing this.

In the guide (E9X ACC Retrofit DIY v1.1.pdf) Nick mentioned having to take apart the connector for repinning. You do not have to take it apart if you get the connector I received. I don't know if Nick was missing the parts shared below.

The connector has a green slider mechanism that locks and exposes pins for extraction. It is super simple. There is a clip that needs to be pushed while sliding the whole piece to the left. When you're done just slide it back to the right.

[pictures attached]

My harness had pins 1(Ground), 2(PT-H), 3(PT-L), 4 (empty), 5-6 (pinned), 7(empty), and 8(Supply).

I simply moved the pin from 5 to 4 for the Wake-up signal. Since 6 isn't being used, I'm going to take it out for another use. Having the green slider mechanism made it a 2-minute job, really.

BTW, as Nick has warned, the ACC sensor module is very hard to attain at a reasonable price. I spent $400 on eBay(US), which I consider lucky, as most are way above that price. Also needed an LDM module because My car was from 2008. I just got the stalk interchangeable with e90 mentioned by another person. Hopefully, it will work. The other parts needed are super easy to source, however.

At the moment, I'm doing an AC compressor replacement so the ACC retrofit is getting done at the same time since I already have everything taken apart. I'm also putting in an M3 replica front bumper for e90. The bumper lower grill will be cut out with Dremel to fit the ACC sensor module.

Fingers crossed, it will all come together without too many issues. Will follow-up update...

vilord · 08-30-2019, 09:57 AM

Since I have the car all apart anyways for the idrive dash install, I'm doing this one too.

Be really careful with the little ribbon cables if you aren't buying a full combination cluster.

Fortunately this happened to the cruise control stalk that came with the car, not the ACC X6 one I'd ordered from spain...

Let me know if u guys had to get it aligned or not

omare90 · 08-31-2019, 12:44 AM

I bought the X6 full combination cluster with lockspring that has heated steering wheel option (also retrofitting). I'm thinking it should be just a full swap and coding... any thoughts?

offtopic but x6 heated slip ring is not compatible with e9x heated wheels

vilord · 09-01-2019, 01:33 AM

yeah x6 ring has a different number of pins and different connector for the heated wheel. I used the ring from the same car that the heated wheel came off of (a wrecked e92 with a blown airbag and damaged combination switchset), the cruise stalk from the X6 combo switch, and the rest of the combo switchset from my e91, because it has rear wiper control that wasn't on either of the others.

You can use the X6 ring if you use an X6 wheel, which is what I would've done if I could've found one, the X6 sport wheel is very nice!
