One of the known issues with the 1.8T VAG engine is that is vents excessive oil vapor from the crank case back into the air intake. This oil vapor not only reduces the engine efficiency but slowly clogs up the intercooler etc.
Also if you fill the oil level past 50% on the hatched area on the dip stick this can get really bad!
Recently I slightly overfilled the TT and this resulted in spewing oil out of the crank case vent into the air intake and ultimately killed the MAF and soaked the air filter in think oil - you have been warned!
There is a simple solution and that is an oil catch tank, Forge Motorsport make one specifically for the TT that fits snugly into the engine bay (The shiny silver cylinder):
