I've been a loyal reader on this forum for quite a while now. I've been able to solve some minor problems i've had thanks to this forum.
I found a video of someone having exactly the same problem as me. http://www.youtube.com/watch?v=KvpzJ0RO2b4
When i start my engine (Vectra C, 1.9cdti, 8v) i hear this chirping noise, but only when doing a cold start. Does anyone have an idea what this could be?
