pump,door locks and trunk fuel door

I hate to say it, but that part lasted 6 years and it's kind of the normal service life. Technicians at a MB dealership are replacing failed parts way before the warranty expires. Recently I have seen one with a failed ignition lock module before it needed the very first oil change. Don't forget, these parts are made by the lowest bidders somewhere in the world - just like anything else now days. Zee
