I recently discovered that fuel was leaking from the front of my car in the vicinity of the fuel filter. The strange thing is that it only leaks when I start up the car in the morning, but it leaves a very noticeable amount on the ground. It doesn't leak after the car is warmed up...
I took it to a mechanic and he found that the #5 injector (which is right above the fuel filter) was slightly leaking, and that all of the fuel lines checked good. He recommended I take it to a dealer for a pressure test of the fuel system. I live in Del Rio, TX which is 150 miles away from the nearest dealer in San Antonio and nobody in this crappy town does work on BMWs.
My questions are:
-Is it commom for a fuel injector to leak fuel like that?
-What type of fuel injector should I get to replace it, or should I replace all of them?
-What should I be cautious of when doing this work?
