Hello everyone,

I have this weird issue with my car... It is an A6 Avant Competition, and the ACC is driving me crazy.
20% of the time it works, 80% of the time it doesn't.
I will post pictures from a dianostic scan and the faults.
You start the car, it works, you drive it for a bit, you go over a bumpy road, it stops working, you go over a second bump, it starts working. It is driving me crazy.
What I've checked so far:
The radars are fixed, they do not move, no cracks in the housing.
Checked the aligment, its fine.
Checked the connectors, cleaned them, no help.
I've tried wiggling the radars and the wires next to them while the car was running to try and replicate the issue but no help, it only happens when driving.

Attached are the pics of the scan.

Anyone has any idea what to check?

Hi you can write error code exactly ?

Hi the code I am getting is:

U1112000 Function Restriction Due TO Implausible Message, it appears sometimes only on module 13 Distance Regulation, or on both 13 and 8B

there should be another error code, the problem could be a rear wheel abs sensor or the windshield camera

I dont have any other codes, it just goes on/off over bumps, like the connection breaks, but I cant find where

if you say it's on bumps, check the rear abs sensors

Thank you, I will check on that
