Turning signal/blinker issue

[Gregor]

Hello...

My C5X7 (2009-2010) developed another irritating habit. Rear left blinker partialy stoped working. I assumed bulb is dead (its almost 13 years old, so normal expectation). Replaced the bulb, checked contacts (perfectly clean, not corroded-like new!) and cable. But, no luck. Blinker dead (the rest ones blinking with double speed), and from time to time it starts to work normal for a short period. I mean one to three activations, and then "dead" again. I measured voltage across bulb contacts, but nothing there, so it has to be something wrong on the harness (i dont think that's really the case) or some relay. Can anyone point me where to look? It would be weard that there would be a separate relay for every bulb, but.. it's Citro after-all.

Thanx in advance!

My neighbour had similar issues with his Picasso, and we fixed it by doing a BSi reset.
