Replace air filter when replacing failed mass air flow sensor on Mercedes-Benz ML350
Had P0172/P0175 error light code come up for mass airflow sensor/TPS....the MB dealer told me the air filter housing was put on wrong...blaming me, but They were he last ones to replace the filters....go figure. Guess the blame game is easier to use than to admit they did wrong! Is anybody honest these days?
