Hey guys,

I've recently been driving my A6 to and from work and the MPG has considerably dropped. I used to get 52ish MPG from the drive and recently I've been getting around 37 to 40 MPG from the same drive.

I recently changed the driverside headlight bulb and had the MAF and airbox removed/disconnected. My first instinct is that something may be wrong with the MAF, so I've attached a link to some live data I captured while driving. Hopefully someone who's good at looking at logs could potentially diagnose the issue. It is due a service to, so that could be the issue.

MAF Log (Mediafire):
LOG-01-011-061-074-101-116-202-938

Cheers!
