Central electric control module location and retrofit help

[Toonbaba]

Hello all
i'm a new member and first post (as I have done much reading through all the great posts!)

My car is the 2016 B9 A4 Saloon and I've decided to retrofit hill hold and front seated heats however I have become stuck ... I cannot find the central electric module. I took apart everything around the driver footwell but could not locate it. any suggestions please??

Also, I have OBD11 and have tried the app and long coding (from a source on this site) to try and activate lane assist (without the stalk installed) but it keeps faulting and turning off my pre-sense basic. any suggestions on what I may be doing wrong? I assume I have the hardware as the car has pre sense basic and high beam assist.

many thanks again!

For the lane assist, it appears on the 2016 A4 you have to undo just this step.

"09 - Heading Control Config>heading_control Byte 35>Bit 0"

Worked for my friends.

Thanks! I'll try tomorrow and feedback how it goes
