Help with ABS on 2013 Audi s5

Hi guys,

to cut the long story short, I came across a front end damaged S5 for silly low money, iv purchased the car and have started to repair it, I currently have a rather major issue with the ABS, from the damage it was evident that the loom for the ABS was badly severed, so far I have joined all the corresponding wires to rebuilt the loom(this is just a test, will carry out a proper repair when all working).

so all wires connected, ignition on and the dash is like a Christmas tree, abs lights on, traction on, speedo not working, tpms light on, power steering gone and various others.

ive connected it up to various diagnostics machines inc our VCDS and non can communicate with the ABS system. the other modules such as steering and instrument cluster all have faults relating to the ABS

Now would anyone have a wiring diagram for the abs system for this vehicle, this would be greatly appreciated.

Thanks in advance

just to add to this, the abs loom has power and ground, so i'm guessing the issue lies with the can bus wires

No one got a wiring diagram for this?
