Turbo engines use oil. That said, I have never had to put any oil in my 135i or 1M (but I change every 4000km)

Your dealer is just talking sh1t.... it is amazing how little they actually know about their product. They probably topped it up with M3 oil (10W60)

I thought I read somewhere that the 1M has a different part # for the turbos thus leading to speculations that they were slightly different also?

Cheers Ian. Definitely something to follow up with the dealer. They will most probably say something different again!!!
