Lane Change Assist Retrofit **Finally Resolved**
 

Hey guys.. I'm looking to retrofit Lane Change assist to my 2010 4E Sport Quattro. Just wondering if someone has successfully done this and if so what parts would I be needing.

So far I figured that I will need the following:

Rear bumper ECU's 4L0910566B, 4L0910566C or 4L0910568B,4L0910568C
Rear Bumper Wiring harness with Lane Assist 4E0971104AC
New Wing mirror caps with Lane assist aperture
Lane assist lights for mirror caps 8K2949145,8K2949146
New CAN Gateway Either 4L0907468C or 4L0907468H
New buttons for the centre dash panel

Is there anything else I've missed?

thanks

You will also need the interior wiring to the correct points like fuse boxes etc inside the car, you will need to make that yourself as its unlikely you will find a donor harness.

So it will require study of wiring diagrams and buying the correct size wire and terminal housings and crimps.

I assume you have access to etka and wiring diagrams?

If you don't you should get that first.

Sounds like quite a fun challenge, I shall keep an eye out for your progress.

Hello Del, Yes indeed I have access to Elsa and Etka. Have spent a lot of time studying them and keeping an eye off ebay as well for donor parts.

I agree that the wiring will have to be custom which shouldn't be a problem as most of the power, ground and CAN can be reached from the rear of the car any ways. Only full length wiring would need to be from the 'Slave' ECU to the wing mirrors and the on/off switch on the dash.

I'll post a picture of the wiring diagram so you guys can give me your input on it. Thanks

Seems like the prices vary wildly depending on what car they came off, shame because I bet you the hardware is the same it will just be the software thats different.

Bit of eeprom magic could save a fortune.

To clarify, is this 'side assist' or 'lane assist' retrofit ?

Side assist is the one with rear radars that will light up lights in the door mirror to warn of traffic in blind spot.

Lane assist is the one that will vibrate the steering wheel if you are drifting out of lane ?

Sounds like your kit list is speccing up for side assist ?

Side Assist and Lane Change Assist is the same thing...

No its not

Have a look at the options

http://forum.a8parts.co.uk/attachmen...5&d=1430159608

well in ElsaWin, Side assist is referred to as Lane Change Assist.. hence why i'm calling it that lol.

Wiring Diagrams attached...

I have both fitted from factory and they are very different...

What you are looking to install Is "blind spot assist" or "side assist"

Lane departure warning or "lane assist " is as IT said...

Although there are two variants of the latter. . "Active lane assist " ( actively steers the car hands free to keep you in the lane )

And normal "lane assist " that vibrates the steering wheel when you start to stray over the lines... "essentially simulates the rumble strips found on motorways. +++

There is also an option that combines both. ;)

But, as described in post #1 this is Lane Assist, i.e. warning lights that there is something in your blind spot.

I guess there are marketing terms, sales terms, technical terms and variations in language.

In the UK, as Guy says, the 'feature' that uses lights on the inside of the door mirrors to warn you of traffic in your blind spot, on the side of you is called 'Side assist'.

I guess at a stretch you could argue that when you indicate, 'to change lane' if there is something in the blind spot, the light flashes brightly to warn you. If this is what folks want to believe is a 'lane change assist' feature then so be it.

None of this changes the fact that really, if you're a half decent driver and check your blind spot and mirrors before performing a manoeuvre, then really its a very pointless, verging on annoying 'feature'. Its one of those I would quite literally only have to have to fill a blank on the dash and would/did/do never use +++

What settings can you change under Audi Side Assist?

Sorry, I should also say each to their own, and regardless of what its called, if you want it, crack on. No one has done it to my knowledge, but probably more through a cost vs benefit than a technical limitation.... +++

What about if you had a freak accident when out, from doing an impression of a chicken and hurt your neck so badly that on the way home you couldn't check your blind spot?

Talking from experience there mate? :ROFL:

New law coming up:-

Do not drive after a funky chicken

I Have actually retro fit this for a Customer it involved The dashboard insert with button, the wiring loom, the sensors that go in the rear bumper, and the mirrors housings and internals,

As for what can be adjusted ... Nothing other than the brightness of the light +++

As Ian said .. it is a tad gimmicky however having said that late at night when your driving with lots of traffic behind you the auto dimming mirrors on the face lift are far more intense than the Pre face lift they are almost Blue they are so dark that it did actually assist me a couple of times when ive been tired and got complacent after a long drive

If i didn't have it as standard its not something Id rush out to Buy ...

Hey do you happen to remember which control modules did you have to code to enable the system? thanks

I can neither confirm or deny your allegations :ROFL:

So I did some research today into the wiring of the wing mirrors. Turns out that the wiring and connector for the Side assist mirror cap lights are present. The blue/yellow wiring runs from the wing mirror harness to the 4 pin connector in the door harness. However from there all the way to the rear of the car will need to be custom fit.

A few snaps...

From door harness to the rest of the car, the blue/yellow wire isn't present. According to ELSAWIN, from this point the wiring changes colour to Purple/Blue.

If anyone is looking at doing this, I spotted these S8 mirror caps with side assist cutouts:

Not genuine though :(

For Lane Assist retrofit wouldn't you also need the different indicator stalk, windscreen and windscreen camera/sensor?

Nope as I'm looking to do Audi Side Assist retrofit ( Lane Change Assist). In elsawin Side assist is referred to as Lane Change Assist.

Hey guys i am in the process of retrofitting this.. All is set but i'm having a minor issue with the wiring.

Can someone explain the wiring on the last page for me please.

What happens at connection B565 in the main wiring harness... Do the wires from both doors join here to connect to pin T10v/4 to the bumper connection?

I've got the following error message at the moment as a result of this..

Thank you buddy.. much much appreciated :)

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?
