Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The purge value for the emission control system, makes a tapping noise in the engine at idle, as if the car is low on oil. When I took this in to the dealership to see what the tapping noise was, they explained that a loud metal tapping noise was normal on the Mercedes. They stated they would put a new "purge value" in the car to see if that would quite the loud noise in the engine. Upon doing so, the car began jerking back and forth violently when attempting to accelerate. The problem becomes gradually worse, the check engine light comes on, the car begins consuming large amounts of gasoline (about 8-10 mpg), the car will rock from side to side at an idle stop and will hesitate for 10-30 seconds, when attempting to accelerate from a stop.
