What is this wire please?

[Nathan Barnes]

Hi all

I have just cut through a wire with an angle grinder. It goes through the passenger side rear wheeltub (it's the thinner wire on the right hand side in the picture. It has 3 wires - Black, Brown, Blue)

Can anyone identify what it does please? Thanks!

Are your abs lights on by any chance?

 

[Nathan Barnes]

No, they go off as normal.

I think the other (thicker cable) is for the ABS sensor, but not sure.

Could it be for the rear xenon sensor? Anyone?

Could it be a control wire for the Haldex system?

I've just run it around the block and VCDS has thrown up:

Address 01:Engine

17743 - Engine torque monitor 2: Control limit exceeded
P1335-35-10 - Intermittent

and

Address 22:AWD

00526 - Brake light switch - F
27-10 - Implausible signal - Intermittent
00532 - Supply voltage B+
07-10 - Signal too low - Intermittent

I can't remember ever seeing these faults before.
