You do not say which engine you have but I suspect that is the variable valve timing solenoid. Either the bolts are loose, the gasket has failed or the plastic part is cracked. The solenoid lists for $168 but Genuine Audi Parts has it for $121. I would start by cleaning up the oil and then touring the screws. Check again in a week or two. If that does not fix it you will need to remove it and have a closer look to see if it is the part or the gasket.
Audi calls it the Cam Adjustment Valve N205 (sometimes referred to as Camshaft Adjustment Magnet) which is different than the Camshaft Adjustment Actuator (also sometimes called Camshaft Adjustment Solenoid). Audi parts naming is confusing and inconsistent.
This is the part for the CYMC engine. Just to screw with your head Audi has used N205 to describe different pieces over the years. Audi A4 allroad Parts | FCP Euro
The service manual implies that there is a seal or O ring (part 9) which is what might have failed; but, I was unable to find that seal / O ring in the parts listings.
The service manual says nothing about having to go through an adaptation after replacement (its just an electromagnet which pops a pin out and presses on an actual valve to control oil flow) so it should be just an unbolt and bolt back in (with or without seals / O rings). If there is no adaptation required it should be a fairly low cost repair (at least low cost for an Audi) or quite doable at home if you are so inclined.
If the oil leak is coming from the body of the 'valve' then its time to replace. If it is leaking around the edge / mounting flange I might be inclined to wipe off the oil, monitor it and perhaps live with it if it doesn't get bad. Get a small inspection mirror and check to confirm where the oil is coming from.
Your 2.0 L FWD will not be a CYMC engine. When referring to the engine it is best to use the 4 letter engine code which should be on the production code sheet.
N205 has always been the identifier for the intake bank 1 VVT adjustment solenoid. But the physical device that contains the N205 unit varies with different engine families. The EA113 used a combination unit that contained the N205 "magnet" and the oil flow control valve unit, while the EA888 uses separate N205 "magnet" and control valve pieces. Since the Gen3 has N205 and N318 (exhaust bank 1), just going to call it VVT magnet.
On the EA888, when you pull the "VVT magnet", you'll see there's an o-ring on the inside of the cam end, item 16 in the image posted previously. That should be replaced anytime the VVT magnets are dismounted. The outer seal, part 9, is only replace is necessary, but if it's old, it'll be a rock, replace it.
