Slight engine oil leak from the turbo air intake pipe

Hi, My TSI vRS has just had it's first oil and filter service.

I asked the dealer to investigate a slight engine oil leak from the air intake pipe joint to the turbo that connects to the air filter casing. Inside the pipe there is only oil residue and is not pooling, but it's enough to leak through the joint onto the mounting bracket. The air filter is dry and not affected.

The response was that this is 'normal' and can be expected.

Please, has any anyone with the EA888 engine got the same issue?
