There's a ticking noise under the bonnet on my '02 E240 W210. It's coming from a little electro-pneumatic or vacuum gizmo just by the ABS pump.
What is it and does the ticking matter?

Start to worry when the count down reaches 10, 9,8,7,........
 
Tank purge valve by the sounds of it. Nothing to worry about if that's the case. Google a picture, see if it matches.
 
Thanks Jobsworth. That's the very thing!
