Got my car back last week after getting the 'increased emissions' warning, SES light, and 2722 code. The tech tested the fuel pressure - the ITSA indicated pressure was 4.5 bar, but the actual measured pressure was only about 3 bar. I am amazed the car still ran.
In addition to replacing the low pressure fuel sensor, they also replaced the control unit for the fuel pump (EKP). Stored code was 27CE. The not-always-stable idle and low speed bucking when cold that I thought was normal is now gone.
