The never ending lean code
Po171
174. Bank 1 and 2 lean Changed turbos Valve cover and gasket 2 smoke tests performed. No air duct leaks from what I can see New symptom only once 29f1 (fuel pump plausibility ). Not sure if that’s the fuel pump or something else causing the pump not to work properly. Anything helps. I need an expert on e60 2008 535xi. |
