Just curious if anyone else's gas gauge needle drops a lot once you get off the highway. Both the MKII and MKIII do this, it usually drops 1/4+ a tank but then gradually goes back up but not nearly where it was. I was wondering if this is common or an actual issue with the evap or emissions system or whatever that can be solved.
Things I tried were downshifting thru the gears to eliminate breaking didnt make a difference but keeping it in gear or puting it in neutral and coasted with light breaking did help a bit.

mine doesnt even work. its stuck on full and the little light is on... also got tips of it might being the sending unit. so ur best shot is to check the sending unit or replace if u cant check that.

Stuck on full AND the light is on? Ain't that a birddog. If you fill it up will the light go out?
