My son took the car to Washington DC for the inauguration and a few days after he arrived i get a call from BMW assist saying there was an engine light on. After making arrangements to get the vehicle to the nearest service center, today they found that it was an exhaust filter that was bad. Now to be honest, i have never heard of such, I mean really an exhaust filter? I have heard of Air filter, fuel filter, oil filter, tranny filter, cabin air filter and even a catalytic converter which in itself is kind of like a filter but not really.

What the heck if the exhaust filter? CAn anyone enlighten me?

BTW he has pictures from the Oval Office. Can't wait to see them. And he is safe on his way home.
