I have a 2004 Volvo S40 2.4i that is displaying the code P0172: System too rich Bank 1
I've checked the hoses, they're fine. Replaced the MAF sensor with a brand new one. Checked the fuel pressure, it's OK. Cleaned the fuel injectors twice. Took the car to a Volvo service center, they said the oil trap housing needs to be replaced, but it was just done 3 years ago!
