I have a 2003 TDI, and have noticed that my car always has air bubbles flowing through the Clear fuel line. Do I have an air leak in the fuel system?
Where would I even start looking for it, as I have not seen any fuel leaks/puddles, or likewise
I've had air bubbles in mine for 100K miles, don't worry. As long as you see fuel running through it your fine.
Just remember, when you get around to changing your fuel filter, to fill it with diesel or Power Service before you start the car.
Thanks, I was just wonderin'
Noticed it was doing this basically since day 1, (90 miles on her when I picked her up) and they were still there 13000 miles later,
No secondary problems (other than a heat soaked turbo, But that is unrelated
) just bubbles in the clear fuel line regularly(always when idling, small ones moving).
