Hi, not sure if this is the place for this type of post but here it is anyway. Bought a used 2010 Kia Ceed 1.6 diesel a few weeks back and I've noticed an odd clacking noise when accelerating at low speeds. I've uploaded a video of the noise here, it's best heard near the end of the video. Sometimes this noise is very loud, other times it's not as such. It doesn't make this noise at all when idling, only under load and even then it doesn't happen all the time. Any ideas of what it might be?
