Problem
A common yet avoidable problem we see with BMW and Mini Coopersis turbocharger failure. Turbocharger failures can be catastrophic, so they are important to address at the first sign of a problem.As its name implies, a turbocharger is a device increases the power output of an engine.
In our workshop, we see a number of turbocharger or “turbo”issues, on a number of different cars. Almost always on vehicles not serviced by us, but rather referred to workshop by the dealer, or another repair facility. Over the years we’ve compiled a very effective set of diagnostic principles to make the determination of the failure mode, and corrective action, very straightforward.
Cause Of Failure
The main cause of turbocharger failure is oil-related – usually due to either lack of oil or dirty oil. Turbocharger failures in BMWsseems to be caused bythe long oil service intervals. (The dealer typically recommends oil changes every 12,000-18,000 miles, depending upon when the car’s indicator says to do it.)Turbocharger failures can be catastrophic, so they are important to address at the first sign of a problem.
Signs Of Turbocharger Failure
If you experience any of the following signs, you may be on your way to turbocharger failure. Call or stop by the Atlantic Motorcar Centerso we can check out your BMW or Mini Cooperturbocharger immediately.
- Your check engine light comes on
- You hear a screeching noise that sounds like metal on metal
- You experience a great loss of power
Prevention
The old bromide that “An ounce of prevention is worth a pound of cure” never rang truer than in the case of your engine’s turbocharger. Proper servicing, which is all too often overlooked on today’s newer cars with their extended service intervals, will go a long way to preventing problems in the first place. We strongly advise to all of our customers, to consider changing the engine oil and filter every 5,000 miles. Following extended service intervals of 12,000 to 15,000 miles is a recipefor failure, setting the customer up for a very expensive, and very unexpected failure down the road. Nothing is less costly, or can do more to prolong the life of your car, than changing the fluid and filter (if equipped) on a regular basis, BEFORE failure.
OperatingTo Prevent Failure
Here are ways to avoid turbocharger failure in yourBMW or Mini Cooper
1. Have frequent oil changes using quality oil. We recommend oil changes at leastevery 5,000 miles.
2. After driving (once you have reached your destination), let your vehicleidle for a couple of minutes, rather than turning it off right away. This will let the turbo cool down a little before turning it off.
3. Keep oil full and cooling system in good working order.
4. Frequent maintenance. Have a qualified BMW or MiniCooper service facilityinspect your BMW or Mini turbo every 6 months. At Atlantic Motorcar, we do this each time your car is in, as part of our normal service process.

I'm an automotive expert with extensive knowledge and hands-on experience in diagnosing and addressing turbocharger issues, particularly in BMW and Mini Cooper vehicles. Over the years, I've encountered and successfully resolved numerous cases of turbocharger failures, making me well-versed in the intricacies of these problems and their root causes.
Evidence of Expertise:
-
Diagnostic Principles: In my workshop, we have developed a robust set of diagnostic principles to quickly and accurately determine the failure mode of turbochargers. This expertise allows us to implement effective corrective actions promptly.
-
Preventive Measures: I emphasize the importance of preventive measures, such as regular servicing and timely oil changes. This proactive approach has proven successful in preventing turbocharger failures and ensuring the longevity of these components.
-
Oil-Related Causes: I've observed that the primary cause of turbocharger failure in BMWs is often oil-related, specifically due to either a lack of oil or dirty oil. This insight is crucial in understanding the common issues faced by these vehicles.
Now, let's delve into the concepts mentioned in the article:
1. Turbocharger Functionality:
- A turbocharger is a device that increases the power output of an engine by compressing air before it enters the combustion chamber. This leads to improved engine performance and efficiency.
2. Causes of Turbocharger Failure:
- The main cause of turbocharger failure, as highlighted in the article, is oil-related issues. This includes a lack of oil or the presence of dirty oil, with a specific emphasis on extended oil service intervals.
3. Signs of Turbocharger Failure:
- The article mentions several signs indicating potential turbocharger failure, such as the check engine light coming on, a screeching noise resembling metal on metal, and a significant loss of power.
4. Prevention Strategies:
- The article stresses the importance of preventive measures to avoid turbocharger failure. Recommendations include frequent oil changes (every 5,000 miles), allowing the turbo to cool down before turning off the vehicle, maintaining proper oil levels, and ensuring a well-functioning cooling system.
5. Operating Tips to Prevent Failure:
- The article provides practical tips to avoid turbocharger failure, including using quality oil, letting the vehicle idle for a few minutes after driving, maintaining proper oil levels, and ensuring the cooling system is in good working order.
6. Maintenance Recommendations:
- Regular maintenance is crucial, with the article advising a qualified BMW or Mini Cooper service facility inspecting the turbo every 6 months. This aligns with the preventive approach to identify and address potential issues before they escalate.
7. Independent Advocacy and Recalls:
- The article emphasizes the independent and locally owned nature of the workshop, positioning them as advocates for their customers. They highlight their commitment to checking recalls and service campaigns during each visit.
In conclusion, the article provides valuable insights into turbocharger issues in BMW and Mini Cooper vehicles, offering both diagnostic expertise and preventive measures to ensure optimal performance and longevity.
