I did too but 3 weeks ago my oil sensor took a dump and showed that I was 1qt low then an overfill. The good thing is I bought a dipstick to verify my oil level (which was/is right on), the bad thing is the oil sensor is on back order The oil level reading is a crucial piece of info and should not be trusted to some dinky sensor that can go kaput at any time, IMHO.Well that sucks! Maybe drill a hole in the engine cover. Oh well, I have learned to live with out a dip stick on my 2011 135i.
Unless VW changed the engine cover on the 2013 TDI, there is no need to pull anything on the 2012. It is exposed for easy checking once the stick is installed.I just pulled of my engine cover off and found the ds tube and plug. I think I will order a ds.
