C5X7 permanent error brake lights short circuit to plus

[cit-rotti]

Hello,

First the right brake light failed and then the left one too.
The centre brake light still works.
Permanent fault codes: A4BE and A4BF = short circuit on positive.

The bulbs are not defective - removed and checked for continuity.

How can I rectify this fault - where is the most likely location for this short circuit.

C5 X7//HDI 163//2014/ Orga 13609// VIN VF7RWRHHAEL502563

Thank you for any information.

Greetings Wolfgang

På en del af de gamle C5'ere, og også på Peugeot 307 og 407 har jeg oplevet tilsvarende - der var det noget så simpelt som selve stelkablet til hver lygte der blot skulle udskiftes/forbedres - så løste det fejlen.

Og det er jo rimeligt nemt og billigt at forsøge sig med..

Question: Do these cable breaks also occur in the tailgate area of the C5 X7 (C5 III) - as was more common with the C5I/C5II?
Or is something else the probable cause???
