Faulty rear indicator LED help needed please.

[dt-tdi]

Hi everyone.

I've got a faulty rear nearside indicator LED stiprip on my A6 saloon.
The faulty cluster is on the boot lid and affects a single line of LED's (see attached photo).
The rest of the LED's in the cluster are working.

I've attached the scan from VCDS for the affected module.
Any advice or help would be greatly appreciated.
TIA

Replace the unit.

Replace the unit.

I take it from the VCDS report the fault lies in the light unit and can't be fixed ?

 

[NHN]

Swap sides & see what it does, but ones I've come across have been led PCB corroded water damaged.

 

[dt-tdi]

All fixed now.
Dried the cluster out thoroughly with a hair dryer then left on a radiator over night.
Made a new foam seal and run a bead of clear silicone around the leading edge to hopefully eliminate water ingress.
Finally cleared fault codes via VCDS and rescanned.
All good so far
