Erratic fuel economy
Hi, my 2011 B7 2.0l TDI Bluemotion is giving crappy fuel returns all of a sudden. Was getting 52 to 54 mpg and now I'm eeking 43mpg out of it. Read somewhere it could be in need of a air filter change. Just coming upto 40k, so going in for service soon. Dealers don't know what may cause this when I asked. Had also read it could be a MAF sensor issue. Any one else had similar? What resolved it?
