hi

do you have the paper from the dealer that came with the key? on that paper it says which is the key # and knowing that you look at the proper entry in the CAS

I dont have the ziplock bag the key came in, but I have the piece of paper that came with it:

Anyone know if this retrofit has been completed successfully on an e90? I’m very interested in doing this on a car I picked up recently.

Hi dumitru.o, can I contact you about your comfort access kit? sr5000@fastmail.net

sure, it was done on plenty of e90. it doesn't matter if it s e90, e91, e92 or e893 because the wiring is the same ( almost..)

hi,
sure you can. just sent you an email

thanks

So I checked all the keys with Tool32. It does not recognise the new CA key at all. The two existing keys are number 0 & 2. The new CA key is number 255 (I'm guessing this means invalid key). None of the key positions are locked. Has my CAS been hacked? What are my options?

Another wiring for e91 LHD will go out next week, i am just waiting for the CA key.

[E90SpcGryM3]

So does the whole interior need to be ripped apart? Apart from the wiring needed, there's not much clarification on install: how wiring needs to be routed, what plugs to what, etc.

No it does not.

I’ve got the wiring harness from a donor car and I THINK I have figured out the wiring route.

These parts would be ideal to remove.

Rear seat/bench. If you have folding seats, remove lower bench and right bolster only.
Right side plastic trims that run along the floor
Center console
Both right and front trim pieces under the dash
Both right and front lower kick panels
Right trunk carpet clips- to peel back the carpet panels
Trunk lower carpet
Right C pillar cover
Third brake light/cover
Rear bumper

Wire routing. Assuming the CA module is already installed in its location.

From the CA module:

Run the rear antenna wiring to the rear antenna that goes behind the bumper.
The wiring goes through a grommet on the trunk metal panel and out towards the antenna.

Run the wiring for the trunk antenna behind and under the trunk carpet to the antenna.

Run the diversity antennas wire behind the carpet, through the back seat, up through the C pillar, under the headliner and to the diversity antenna.

Ground wire can be grounded in a ground block in the left of the trunk.

The 2 Canbus wires can be tapped into the Canbus wires in the trunk.
If no Canbus wires are present, you need to run those / wires to the front of the car too with the following wires.


Run the wiring for the following:
-2 center console antennas
-Power wire
-CAS wire
-2 door wires
All these wires can be run together behind the right trunk carpet, through the backseat area, then down the right side of the car. There is a big wire loom there and you can tape it to that loom.
Run them all the way to the fuse box area.

The 2 center console antennas run to the fuse box area and then make a left to wrap around towards the center console.

The left door and CAS wire also make a left at the fuse box and need to pass through the center lower part of the dash to the driver side.



Maybe I made that sound more confusing than it is, but it’s not.

I’ve got all the wiring and locations figured out.
I will tap into power from an existing fuse and tap into canbus wires in the trunk. Then the antennas are simple.

The only 3 wires I need to figure out are the door wires, and CAS wire.
They’re all white, so that will make things easier….

[dumitru.o]

be aware that the BUS wires even though all of them are white, they do matter which one goes where.

this is not the case for e6x or e7x!

for e9x, which we are talking about here, all those three wires go to different pins and it matters which one goes where


the wires goes along the main wiring on the right side of the car, from the trunk under the carpet all the way behind the dash and o the driver's door/CAS. everything goes naturally if you have the wiring in hand

Hi, yes, I was making a joke about the white wires. As BMW made the rest of the wires all colored, except the 3 BUS wires.

Looking at a digram,
On the CA module connector, pin 17 goes to the CAS module.
White wire on pin 1 goes to the driver door.
White wire on pin 4 goes to the passenger door.

This is the only digram I’ve found about those 3 wires.

[dumitru.o]

that is correct! the wires have the same color because they carry the same BUS signal. i don t know why they decided that on e9x each door has it s own wire and CAs a different one and all of them colored "white" while on the e6x and e7x they use only one wire ( one output from the CA module) for connecting all doors and CAS.

anyway, we take it as it is and deal with it

[Andystobbs]

Never the less they must all carry the same signal or else a defective door handle wouldn't cause non start, which is resolvable by unplugging CA module thus severing the link between PA bus and TAG bus and letting the PA bus function normally and transfer data between DDE/DME and CAS.

So you can confirm that the white wires and pins I mentioned above are correct?

Do you know which pins from the main CA module connector are the empty ones for the rear doors?

E70 has rear CA door handles.
I want to add rear CA door handles to my e90 with this retrofit.
I was told there is spare pins on the CA connector and that I just had to add the extra wires for the rear doors.

[Andystobbs]

E70 has a different CA module and totally different pin out. I bought an E70 module in readiness for adding the rear comfort handles. Didn't use it in the end, re coded the E9x module and added the rear handles in parallel with the fronts.

[Serf27]

This was my initial plan when talking with someone else about the retrofit.
I was told to just add the extra wires to the CA connector instead.
If not possible, then I’ll just splice the front door wires to the rear door.
This is as simple as supplying power/ground to the rear door handle, and just splicing the CA wire to the front door white wire, correct?

[E90SpcGryM3]

All this extra info makes my head hurt and doesn't make me want to tackle this project. Lol

Pictures would be really helpful

I felt the same way.
Once you have the wire harness, it simplifies the project.
Pictures or visuals simplify it even more.
The donor car I got the harness from had almost the entire interior removed. Once I saw how the wiring was laid out, I felt better.

I’m not sure when I’ll install the harness, I figure it will take a day to get all tan through and wired in.

I assume the most difficult part of this is the new wires going through the body to the door harness and removing the fuse box for power. I removed the fuse box the other day and it’s not the greatest thing.

Here’s the wire harness with the 2 door harnesses I got.

Awesome. Take lots of photos please!

[PichaDis11]

There's work involved either way you look at it. You're just adding wiring to the car that's already upholstered. Roll up your sleeves and get to it. You'll get the reward at the end for sure.
From: Someone who decided to make the harness from scratch.

Happy retrofitting!

A second key was ordered for the same car

Hello, I had a question if you pick up door handles that are different colors from your car can be painted the door handles?
