Excessive Oil Loss/Leaks

Certain models of the 3 Series have been known to lose oil at a higher rate than expected, especially at high mileage. Many people think an oil leak will be evident due to the presence of oil under the car, but this isn’t always the case. In the 3 Series, oil can leak onto other engine components, which can cause other issues as well.

If your 3 Series has a noticeable leak or your check engine light is on, you should have it addressed quickly. The 3 Series has a few known parts which can lead to oil leaks, including plastic components and seals which can fail over time. Our team can perform an inspection and locate the source of the leak, perform a lasting repair and ensure your 3 Series is able to retain oil for years to come.

Turbocharger Failure

Part of the reason the 3 series packs such a punch in the performance department is due to the turbocharged engine. Different iterations and trim levels of the 3 series feature unique engine configurations, so issues can vary, but turbocharged engines are prone to some issues.

Common turbo problems with the 3 series often stem from a fuel injector issue, airflow problems, or software problems. Our team is well-versed in diagnosing, repairing, and maintaining the 3 Series’ turbo system. We can typically perform complete repairs in a timely manner, and for a reasonable price.

Water Pump Leaks

The water pump plays a vital role in any vehicle, and this is especially true of a performance car like the 3 Series. Water pumps help coolant run through the engine, preventing overheating and allowing the vehicle to run as intended. When a water pump leaks or doesn’t function, severe engine damage can occur.

The 3 Series water pump is prone to have issues due to excessive heat, wear on internal components, and a known problem with the control panel. Since many 3 Series use an electric water pump, the electrical components are more likely to fail than a traditional mechanical pump. Luckily, we have the know-how to quickly correct this issue or replace the water pump in most cases.

Timing Chain Failure

Perhaps the most harmful yet common issue with the 3 Series relates to the timing chain. The timing chain in many models of the 3 Series is fed through plastic guide rails. When these guide rails break, become damaged, or chip, the timing chain can become slack or stretch. This can cause major engine issues.

If your 3 Series has a strange rattling sound when you turn it on, if you’ve experienced a random loss of power, or your engine is misfiring, you could have a timing chain issue. If you have any of these symptoms, come see us as soon as possible for a professional diagnosis.
