I had a similar situation, and I too thought it was the gas cap. It ended up being the Fuel Vapor Leak Detection pump (believe it or not). The DME code I got was a 3220 DMTL, and a 3221 DMTL, which is the Hex code my program gives me. P1434 and P1447 are the relative DTC codes if that's how your reader shows it.
On my 2011 335i, it is located driver side rear, behind the wheel and next to the exhaust. I ended up buying the part on amazon and replacing myself. Probably took 40 minutes from start to finish, not knowing exactly what I was doing.
Hope this points you in a helpful direction!
