Did you carry out basic settings adaptation work after the valve body replacement? If not try that first.

Thank you for posting a full Auto-Scan. :thumbs: As I see it, you've got two issues... electrical and mechanical.

01772 - Signal from Level Control Pressure Sensor (G291)
009 - Open or Short to Ground

The Level Control Pressure Sensor (G291) is part of the solenoid valve block, there is a T10i connector, the G291 is on /7 /9 and /10. These are wired up to the Level Control System Module (J197)

G291 /7 = J197 /92, green
G291 /9 = J197 /84, green/black
G291 /10 = J197 / 67, brown/green

It looks like /7 + /10 at the G291 should be a 5V referance signal, and then /9 is a data signal back to the J197. So... is the wiring for the G291 to factory design? Did you have the this code before you replaced the valve block?


01583 - Leak in System Detected
Pretty much what is says. The most common issue we get feedback on is leaking airbags. Sometimes people can hear is hissing, others can get soapy water onto it.. and many times it is blind faith in just replacing the strut since that is the most common issue.
