Golf 4 2.8 4Motion fault question

[michael bennett]

I have a 2002 golf 4 2.8 4 motion. Inspecting the car over the weekend I noticed a ticking sound coming from one of the components under the bonnet. I had a look at the manuals but could not identift what the part is for. Its on the left hand side of the engine between the washer resevior and coolant reseviour. Photos attached, can anyone tell me what the companent is. ABS pump?

No photos but going from your description, it sounds like the Carbon Canister purge valve, aka, the "N80". Ticking from that is perfectly normal as it's a solenoid.
