Mk6 GTI CEL - P0172 - System too rich

[Matti89]

Hi.

I've got a mk6 gti with 50000km. The car is completely stock. Driving home one day the CEL came on but I didn't notice anything wrong with the car so I just drove the 5 minutes left to home. Put my obd2 port and ran a error check. Came up with p0172 - system too rich (bank 1).

Any ideas about what this could mean?

Been seeing a few of these lately, tends to be caused by a failing high pressure pump.

Did you manage to find the cause? I am facing the same issue.
