I just bought a 02 BMW M5.
I bought it through a dealer that I know well, the car was repoed previously but I got a good price. He told me to take it to smog myself.
It has the Dinan badge on the back.
I called the shop that installed all the Dinan and they said the car had the Cold Air Intake and Dinan Stage 1 and Stage 2 software installed, and more but irrelevant to this subject matter.
I popped the hood and it looks like the Dinan Cold Air Intake was removed by previous owner and stock has been installed.
I tried to get the car smogged, they reset all the codes and then got the following codes from the Smog Machine:
I am getting peak code P0174 and P0171 -- Bank 1 & Bank 2 Running too Lean.
Now could this be because the Dinan Intake was removed and the Dinan Stage 2 software is still installed?
The car also has a Emissions Recall that I need to do before Smogging the car, will this solve the problem?
I bought the car on Monday. All Wednesday the SES light was gone. I was running Gas Station 76 91 octane. I filled up at Chevron late last night, but I am not sure when the SES light came on. Today it has been on all day.
How come the SES light was gone for a whole day?
Guys help me out i really need your thoughts
