Default Audi lane assist to Active lane assist

Hi all,

My D4 has lane assist, acc stop and go, side assist, night vision ect...

Does anyone know what parts would be needed to convert this to active lane assist as per the 2015+ models ?

Many thanks
Ian

I suspect you would be looking at a new power steering system as the later cars were significantly different in that area, a by-effect being active lane assist.

They no longer had a shaker in the steering wheel, instead using feedback through the column - meaning you didn't have to opt for the ugly 4 spoke to get lane assist.

To be honest - In my opinion any form of lane assist is something I'd switch off on a D4, just leaves you feeling detached (and sometimes confused, when you thought it was turned off but you caught the stalk) but isn't good enough to be really useful

So will the newer model have electric power steering and mine has hydraulic? ...not that I lift the bonnet much but I should know the answer to that.

Is it even remotely possible on a pre face-lift? (I'd really like to have it

Exactly that I believe - so not much chance it will be viable I'm afraid

Just opened up a VCDS scan from a face lift car - they have an additional module for the electronic power steering

Quote:
Address 44: Steering Assist (J500)
Part No SW: 4G0 909 144 T
My pre-facelift doesn't have that module.

The other (slightly more useful, maybe) feature with the face lift is the "Parking Assist" which can park your car for you - all be it in a dim-witted way that will leave you embarrassed to get out afterwards (lot's more shunting backwards and forwards than it takes if you can just reverse yourself).

Thanks Paul for your help.

I can't find any evidence online to suggest that the power steering system is different. . Just browsing power steering pumps online for 2010+ A8s they all seem to look the same even up to 2015 units.. seems to be no pully on the unit rather a motor ...

I'm most certainly no expert mind so I could well be looking at the wrong thing!

If they all have electric hydraulic power steering is it possible the only difference is the address 44 unit? ... maybe some kind of motor that turns the wheel on the steering column?
