Audi A4 Avant 2005 issue

[Luke5tone]

Hi all,
Just joined up and wondering if someone can help with an issue.
My dad's A4 Avant has had the engine management light come on and there was a strong smell. 
Popping the bonnet I noticed what looked like smoke and I'm guessing a disconnection between a part of the engine.
Please can someone let me know what they think the problem might be and any idea what the cost for repair may be.
He's in his early 80's, I can only get round there once a week and worried he might get taken advantage of.
Thanks in advance.

Hi it looks like the PCV valve has become broken/disconnected and is spraying crankcase gas and oil vapour over the engine, the part wont be that expensive and I should imagine about an hours labour easy fix.

Much appreciated Steve. That's great. I'll let him know and we'll get it sorted!
