Got my car mk4 gti serviced for it's 105,000km, and days after blowing blue smoke, turns out they had a new mechanic on and overfilled the oil, went back to get it drained, ended up being close to 2L excess oil.

What concerns should I have apart from the issue that there was no supervision on the new mechanic, is there any issues that may arise from this? drove probably 150kms with too much oil in the car.

Just so I have some knowledge in case anything goes wrong,
nothing seems to be out of place, no smoke and running fine,
cheers
