I was having P0172 and my car was giving engine light in sometimes. For example when I washed my car engine light gone . Today while get changed the spark plugs, the mechanic noticed that my oil smells gas. After that he said you have to change the high pressure fuel pump but if it doesn't work properly it should give error in OBD isn't it? I had just P0172 and they deleted the errors. Now I don't have any errors. I got a problem before. My turbo leaked too much oil [I got it replaced(new Wastegate,vacuum pump, turbo renovation, oil and filter changing )] maybe because of that oil leaking my o2 sensor affected and can't give correct values and because of that car works rich? Or my spark plugs wasn't working properly or high pressure pump doesn't work properly? What should I do? I don't want to drive in this condition.
