BMW Oil Leaks

BMW vehicles are the most luxurious and high-performing automobiles on the market. They appeal to a diverse market with their sportiness and elegance. Since BMWs are designed with premium parts, it can be disheartening when simple malfunctions impact their owners. One of the most common problems for BMWs are oil leaks. Every car will experience a leak from time to time. However, if you ignore the problem, it can lead to major complications in the future.

How To Determine An Oil Leak In Your BMW

The most apparent sign of an oil leak is if you see a puddle of oil underneath your parked car. A pool of oil may be the first red flag for BMW owners.

Another sign of a possible leak is smelly fumes emitting from your motor. The issue with oil leaks is that they can be hazardous to the environment and damage your engine. If a leak is left untreated, permanent engine damage can result.

Common Causes Of Oil Leaks In Audis

Damaged Or Aged Seals

The pressurized system that houses your engine oil has gaps in it that are filled with valves or seals. If these parts become damaged or over-worn, they can cause oil to escape from the system. Furthermore, if a seal becomes damaged, it releases intense pressure from the system, inhibiting oil flow to the engine.

Broken Oil Pan

Damaged oil pans usually result from an auto accident or when you run over debris on the road. Considering that the oil pan sits close to the ground, it is very vulnerable to punctures and damages. It is best if you are cautious and avoid road obstacles as much as you can.

Filtration Issues

Oil filters collect high levels of debris from regular wear and tear. A dirty or faulty filter can create leaks if not monitored regularly. Each time you service your BMW, ask your trusted mechanic to either change or check your filter to ensure it is clean and intact.

Loose Oil Cap

Sometimes human mistakes happen during oil changes – mainly if the person handling the oil change is inexperienced with BMW vehicles or simply rushing to do the job. While it’s normal for some oil to leak after a change, seldom leaks are due to an unfastened filler cap.
