98 740iL - MAF sensor and service engine light
I have a 1998 BMW 740IL
Went to dealer to have a different problem fixed. While it was there the Dealer said my MAF sensor was bad and would need replaced to solve the Service Engine light. Car ran fine. Just the light was on.
Anyway, Had a friend with a couple of scrap 740IL's ( by the way, he still has them Good engine's and body parts if you know anyone looking to purchase ).
I took one of the MAF sensors off and put it into mine. After several hours of driving the light went off.. Awesome! thought I was fixed.
A day later, the light came back on.... Any suggestions? I took another MAF off the other spare BMW. LIght still on.
Car is running fine. Just the light is on.
Any suggesions would be appreciated.
