ticking?

[c320]

does anyone know what this part is?

i thought i had an issue with a tappet but this device seems to be ticking intermittantly? You can feel the vibration when ticking and then suddenly stops. Its located near the front of the engine and directly next to the esp. Sits in front of the front right shock.

anyone know what this is and what it does? and am i causing any damage?

thanks

hard to tell from your photos but could it be related to your ABS ?

Could you do a wider shot, I've no idea what I'm looking at?

no as this is controlled by the ecu? which is seperate to this?

If you look at the photo, you will see a black and red cable dissaper into a plug to the right of the ecu. There is one pipe that runs on top and in front of this device and they both seem to connect via a rubber housing at the bottom.

I get no fault codes, abs, bas, esp all working fine. Drove and locked the wheels and everything seems to be ok?

somemore photos attached.

There is also a black plastic lid which opens and closes on one of the pipes that leads into this? apologies for the poor photos, its late!

It looks like some kind of emission control valve

Its the purge control for emission and yes it does tick sometimes when it is working.
