I picked up a 2003 Jetta with the 2.0 (AVH? I think) and 5speed. Car only has 110k but has some odd issues.
First, it has an issue between the gas tank, gauge, and pump. I’ve found that the car runs out of gas when the gauge shows ~1/8 tank left. Low fuel light does not come on. When refilling, it will only accept ~12gal. Gas pump clicks off, and fuel gauge will not go above 3/4-7/8 reading.
Second, I suspect the fuel pump may be weak/failing. I’m not sure if the tank/gauge is faulty (and the tank truly is empty), or the pump cannot harvest fuel below the 1/8 level.
The car will shut off the first time. If wait 5 mins, car will restart and run for another ~10 miles, then starve and die again.
Even with a full tank, the car idles a tad rough. The tach doesn’t fluctuate much, but I notice a rough idle within 150-200 rpm.
Third, it possibly gets subpar mileage. I have achieved ~29mpg Highway at consistently 70-80mph.
My mother complains profusely it gets 21 city. But she also complained to no end when my ‘04 Focus returned her “only” 28city, so who knows...
All of these symptoms (to me) point to a weak fuel pump, but if you drive it with the understanding that it only “holds” 12gal, you would likely never have any issues.
Not sure if I should put a gauge on the fuel port or what
