Hey,
I have did some reading but there is nothing substantial on this topic other than its a very expensive retrofit. I want to attempt to do it as I am keeping my BMW for a long time and always wanted this feature.
I have a 2009 BMW 335i xDrive Coupe.
I will post with my progress on this, cost and pictures as I get to the install phase. I know that programming will be required which not my strong suite so will need to find someone to do this part. I have the cable, NCSExpert and Edibias all functional as was used to do simple programming and programming of the Front and Rear PDC.
I got this so far:
- Control unit passive go (61359134708) (x1) - $60
- New Truck antenna bracket - $3
- Used BMW Left FRONT DOOR HANDLE COMFORT ACCESS - (51217207565) - $40
- Used BMW Right FRONT DOOR HANDLE COMFORT ACCESS - (51217207564) - $80 (need painting)
- Bumper antenna (x1) and Interior Antennas (x3) - (61356922212 & 61356922211) - $55
- Driver and Passenger wiring door harnesses with comfort access - $50
- Comfort Access wiring harness, i couldnt find one on ebay, so this was made for me by Dumitru (he is a member on the forum). So if u can't find one or make it, he definitely can make it for u and the price is reasonable.
Also I found the below link, I will use this to figure out the antennas location.

So below is an update of what I have done. Progress is slow as it is my daily driver.
I have removed the back seats and rear console to install the rear CA antenna. I also removed the trunk liners to install the CA passive GO module (goes in the PDC device holder) and the luggage CA antenna.
After you remove the liners from the trunk you have to also move aside the insulation to access the PDC device holder. There are 3 screws holding it so unscrew them and then try to wiggle it out. Once out but the CA Passive GO module and then reverse the instructions on how you got it out.
Removed the center console trim. It's straight forward and there is a lot of DIY instructions and YouTube movies. Below are few pictures.
Below pictures connecting CA wiring harness to the PDC module plug.
Below are pictures showing the connection of the CA wiring harness to fuse 61 in the JBE fuse box. For my car it is pin# 10. I took the glove box out. There is alot of DIY out there to describe how.....and then you have to remove the 4 torx screws to be able to get back to the plug behind the JBE fuse box.
Below are pictures showing connecting the CA wiring harness to the passenger wiring harness. Same applies for the driver side. For my car it is as follows white wire to pin# 12 and red wire to pin# 25. Use an 8mm socket with a small rachet to loosen the screw holding the plug from the door to the car. There is a black thing that you will need to pull it out to disengage the plug from the wiring harness of the door. Once unplugged make sure to take off the blue thing before attempting to put in the pins into the plug.
Below is connecting the CA harness to the CAS module. Ofcourse take the 3 screws off to remove the under tray under the steering wheel. Disconnect the various connectors and get it out of your way. Unplug the CAS connector. Connect the wire from the CA harness to pin# 30 on the CAS connector. I used a quick connect.
Passenge door wiring harness and the CA handle install. Be careful not to break any of the plugs.
Programming was done by Dumitru. VO $322 adding comfort access.
After I purchased the CA key (Dumitru got me the key and ofcourse the option was added to my Car VIN as seen below). I used
www.bmwvin.com to confirm
I got the key. I put it in the slot and turned the car on to make sure the car recognized the key. Once this was completed I turned the car off the key out. I turned the car on without the key in the slot and BINGO the car turned on
Project was success. Below is a clip to show the CA retrofit in action.
Let me know if any one have any questions. Hope this helps
