Low fuel pressure sensor out HMMM not sure but doesn't sound good LOL
You can also check your tune and make sure your gauges are configured correctly.

My exhaust is actually leaking from three places where a terrible shop did a resonator delete. I am waiting for my new xpipe to come and my tips before I get it fixed.
I realized that even in a "highway" commute I hit 9/10 traffic lights that are 3-4 minutes long so I guess MPG can still suck even if you do 90% highway driving but get stuck at 10% of the lights. Today I hit every light each time I went out.
My tune is map 1 on JB4 I usually run it very conservatively. I also did the Alpina flash so the car gets in 6th gear at 40 mph and and needs more throttle push going uphills and I live in a hilly area. Perhaps the flash is why the mileage is suffering, I just did it Saturday.
