Signs Your BMW Has an Oil Leak

motor oil

Motor oil plays a vital role in maintaining the operation and functionality of your car. It keeps all the engine parts lubricated and ensures a longer lifespan of your vehicle.

If you own a BMW and notice an unpleasant odour and leakage under the vehicle, there is a high chance that you have an oil leak somewhere. Oil leaks on your BMW can be very dangerous and costly, so it’s best to fix them as soon as possible.

Keep in mind that a puddle of oil under your car isn't the only sign of a leak. In fact, on oil leak can have several causes, including worn or damaged seals, a faulty connection, or a loose bolt or nut. Here we compiled a list of the different warning signs and areas on your BMW that signify an oil leak. Keep on reading to learn more!

Unpleasant Burning Smell

Always pay attention to any unusual smells around your BMW. Burning oil has a very distinct and potent smell. When engine oil spills out from its reservoir or leaks onto the hotter areas of the engine, it will heat up and emit this distinct smell that you won't be able to miss.

As soon as you notice any strange odours, take your vehicle in to get serviced to ensure the excess oil doesn't cause more serious problems.

Constant Overheating

Every engine needs oil to help with lubrication and cooling, which limits friction and keeps the overall temperature down. When the oil is leaking and running out, your BMW engine will start overheating regularly.

Don't ignore your engine temperature gauge, and immediately stop driving as soon as you notice it is getting too hot. Having a professional inspect your luxury car is always recommended in these situations.

Damage to Parts

A BMW oil leak often comes from either the drain plug or the valves. As you give your engine a regular inspection, take a closer look at these areas to see any apparent damage. If your BMW engine is leaking oil, it is usually caused by a damaged gasket, a cracked valve cover or a cracked pan. Look closely at all its components and devices, and if you see any apparent damage, contact your local auto shop in Calgary immediately.

Smoke Coming Out While Driving

As the oil burns on the engine, it will release a white, thick smoke. If you see a smoke coming from your engine, it’s likely that your car has an oil leak.

This can be one of the most alarming and clear signs that you have a major problem that needs to be taken care of as soon as possible. To avoid engine failure and costly repairs, take your BMW to a reliable mechanic right away.
