	1.8T, A3 Fueling issues. Experts needed! « on: February 20, 2018, 01:24:53 PM »

Hello,

My current problem is that after turbo upgrade fueling looks very strange
Is this a fuel Pump? Or oxygen sensor? Something else ?
I hope somebody can help me to sort out strange behavior of my car.

To the car:
A3 2003 m.y 1.8t K04 turbo Saab red injectors p/n 0280150431.

screen shots as well as CSV logs are attached.

I wonder, if the fuel is not there should not EGT be high and ignition retarded?

Thanks in Advance,

That looks really really bad. Probably pump or fpr related.

Definitely not safe to run.

Also, you might want to taper your req boost. your turbo can't keep up.

Thank your opinion Nyet,

As I wrote above if this is fuel supply related, than should not EGT be very high and ignition retarded?

Replaced oxygen sensor today. Everything is working as it should.

The Sensor was defect.

Consider reducing req boost or might eventually throw a code.
