Hi i need some help from owners with side assist fitted.
I've been trying to retrofit this system but I am stuck with an error code caused by the driver side side assist light. 02854 - Warning Lamp for Lane Change Assistance (in right exterior mirror) (K234) 010 - Open or Short to Plus Freeze Frame: Fault Status: 01101010 Fault Priority: 3 Fault Frequency: 1 Reset counter: 227 For some reason, that light is always lit up even when the iginition is off. I tested using my multimeter which shows that there is a constant 12v being supplied to the right light and not the left side. Now is this normal? Many thanks

I'd say no and your error is telling you the same.
You need to check the wiring is correct and free from problems from module to the light

I reckon it might be the Master module itself causing the problem.. as for the wiring i've checked several times and everything seems in order. I even swapped the mirror lights with each other to check for issues and the driver side still remains lit up.
I'm trying to source another Master module 4L0910566C on ebay but most are over £100... hmmmmm

Finally I have been able to resolve the error codes!!!!
The issue was the custom wiring harness i made for the bumper.. I'm guessing there was a split wire somewhere which caused a grounding issue for the driver side mirror lamp. Just need to take the car for a drive now hoping that the system will calibrate itself, if not it will be a trip to the dealers for it. Won't be cheap though as they want a full 1.5hr of labour for the task!

So here's another issue..
Side assist is drawing too much current while the car is 'sleeping' and ignition/ignition off. I connected my multimeter to the fuse i retrofitted (In the left fuse box), fuse 36, and it's showing me that there is a current draw of 331 milliamps which i'm guessing is causing my battery to drain significantly. There are no error codes stored on the side assist modules which would indicate a power issue with the units. My understanding is that CANBUS should put the modules to sleep when everything is completely off but that's not what's happening in my case. Any help or advice would be appreciated. Many thanks

Hi neeldub, did you ever get this fully working? Was it worth it?
