Failure to maintain your BMW oxygen sensors can give you trouble down the road, though most new owners never stop to consider this when they first purchase their vehicles. BMWs are renowned for their first-rate engineering and handling, making it even more tempting for drivers to blow off a few standard preventive measures. The last thing you're worried about after taking delivery of your sporty new Beamer is whether your oxygen sensors are in good shape.

Thousands of miles later, road debris, salt, oil, and various chemicals can all disrupt your oxygen sensor's ability to regulate air flow. Lead from gasoline can worsen the damage, as can silicone from leaking coolant. Lest you think this is of minimal importance, consider that malfunctioning sensors can drag down fuel efficiency by misreading the car's air intake. Moreover, this neglect can lead to problems with your catalytic converter as well.

The Environmental Factor

It's one thing to cost yourself hundreds of wasted dollars in fuel costs. It's something else altogether to rob the environment of its natural resources by coughing CO and hydrocarbons into the atmosphere. Of the roughly 50 percent of drivers who exceed their emissions limits, almost all do so out of sheer neglect, which is a shame.

Some states such as California have cracked down on all drivers, forcing them to consent to increasingly rigorous tests. For BMW owners who aren't looking to spend hundreds (or even thousands) of dollars to come into full compliance, the solution is simple: take care of your oxygen sensors. You don't have to replace them frequently, but it's a wise idea to monitor their cleanliness as you begin tacking on serious mileage.
