i admit that i am a somewhat of a lead foot but this is ridiculous...i'm filling the tank every 3-4 times i take the s4 out. it only started happening in the past month or so. on long highway trips, i can probably get around 300 miles to the tank but it's the local city driving that's killing me.

i've stfa and read ALOT of things that could be causing my recent poor gas mileage...

- winterized gas
- torn BPV
- failing MAF
- dirty plugs
- dirty air filter

my car is still under cpo warranty, so ideally, if it's a torn BPV or failing MAF, it should be covered under warranty. i just brought in the car for it's 35K service at Riverside Audi not too long ago so spark plugs and air filter SHOULD be clean...i really wonder if they bother replacing them...

any other suggestions before i setup a service call?

I agree about the MAF
