overfilling oil -possible probs?

[petercam]

I just checked the oil level on the wifes Passat TDI 130 after it had been serviced by the local VW garage. I was a bit miffed to note it was overfilled by about a 1/2 litre.
I am intending to take it back to get it drained to the correct level, but wondered if there were any other short/long term problems this might cause?
