    My 2004 211 i6 320cdi makes a slight ticking noise, only 'on throttle'. Noticeable from 1200 rpm to 3000. Only hear it when accelerating, even slightly. Goes as soon as you back off.

    sounds single cylinder ish. Ie tick......tick

    took my mate / mechanic out and demonstrated and hes was stumped.

    any ideas?

    I had something like this too ages ago. Had the oil changed, ran it on v power for a while and it was gone. Never came back.

    Possibly a noisy injector. Put either a tank of V-power through it, or a bottle of a decent injector cleaner in the tank and see if it improves.
