Used BMW 5 Series (Mk7, 2017-2024) Buyer’s Guide

Posted on 8 April 202510 April 2025 By Evan Rothman

Feeling fancy? This is one mouth-watering Beemer for car enthusiasts and tenderpreneurs: the BMW 5 Series Mk7 that was available in South Africa between 2017 and 2024. It offers a LOT of car for your Rands, thanks to our favourite word beginning with the letter “d” – depreciation.

When examining the BMW 5 Series, it makes the argument for SUVs melt away. This family sedan does it all with style, quality, and incredible driving composure and feel. The 5 Series has always been an all-around family sedan, stretching back decades and generations of this icon of BMW’s model line-up. This version proves that a sedan can be ultra-modern, luxurious, and fun to drive in a svelte package.

About the 5 Series Mk7

The 5 Series Mk7 was unveiled in February 2017 and hit local dealers towards the end of that year. It was available with a host of powertrain options internationally, but South Africans only had petrol (550i: 4.4-litre V8 with 390kW; 540i: 3.0-litre V6 with 250kW; 530i: 2.0-litre with 185kW; 520i: 2.0-litre with 135kW) and diesel (530d: 3.0-litre with 195kW; 520d: 2.0-litre with 140kW). Each engine, from the mighty 550i to the 520i sets the standards in each engine category for performance, efficiency, and sonorous qualities.

As usual with the Bavarian marque, a plethora of styling, convenience, sport, and luxury packages could be selected, with the used car market blessed with a predominance of sportier choices in M Sport style to complement the svelte tailored suit of the vehicle’s appearance and under-the-skin execution.

Engines & Performance

Engine Variants

Petrol:

  • 520i: This model is fitted with a 2.0-litre, 4-cylinder turbocharged petrol engine producing 135kW and mated to an 8-speed automatic gearbox.
  • 530i: It gets an uprated version of the 520i’s power unit, pushing out 185kW. It is also paired with the same 8-speed automatic gearbox.
  • 540i: This is a 3.0-litre, 6-cylinder turbocharged petrol engine producing 250kW and is equipped with an 8-speed automatic transmission.
  • 550i: The range-topping engine is a 4.4-litre, 8-cylinder turbocharged petrol unit delivering 390kW and a monstrous 750Nm. It is also mated to an 8-speed automatic gearbox.

Diesel:

  • 520d: This model is itted with a 2.0-litre, 4-cylinder turbocharged diesel engine producing 140kW and mated to an 8-speed automatic gearbox.
  • 530d: This is a 3.0-litre, 6-cylinder turbocharged diesel engine producing 195kW and is equipped with an 8-speed automatic transmission.

Performance

While the 550i’s 390kW of power can propel it from standstill to 100km/h in 3.8 seconds, each of the 5 Series Mk7 models can do that same dash in under 7.8 seconds, which says a tremendous amount of the German sedan’s compelling powerplant choices. However, it remains sedate and composed at highway speeds, and you’d never guess that under the bonnet thumps the industry’s leading engines in each class. Incredible work by the folks in white coats in BMW’s bunkers.

Safety & Technology

The BMW 5 Series Mk7 represents the epitome of executive sedan refinement and showcases advanced vehicle technology and safety innovations aimed at delivering an unmatched driving experience:

  • Safety Features: The BMW 5 Series Mk7 incorporates cutting-edge safety technologies across all models, including standard features like lane departure warning, dynamic cruise control, and emergency brake assist. Higher trims enhance passenger protection with various active safety systems, such as lane change assistance, cross-traffic alert, and evasion aid, ensuring comprehensive driving safety.
  • Technology: Technological advancements are at the forefront of the BMW 5 Series Mk7, equipped with a high-end infotainment system featuring a larger touchscreen, integrated navigation with real-time traffic updates, and a superior surround sound audio system. The digital cockpit boasts a fully digital instrument display and enhanced connectivity features, including BMW’s ConnectedDrive services, which offer remote operations, real-time vehicle analytics, and personalized driver settings that are accessible via smartphone integration.

  • 530d: It achieves a combined cycle fuel efficiency index figure of 5.1-litres/100km, meaning it has a range of 1,294km from its 66-litre fuel tank.

Maintenance Costs

The BMW 5 Series Mk7 is regarded for its premium build and relatively higher maintenance costs compared to more economical brands. Routine servicing for the BMW 5 Series is comprehensive, reflecting its high-end engineering. Owners should anticipate annual oil change expenses to range from R2,500 to R3,500, influenced by the choice of service provider and geographical location. Additionally, the cost for replacing other consumables, such as air filters and brake pads, typically aligns with the luxury market standards, ensuring that maintaining a used BMW 5 Series Mk7 over time in South Africa is an investment in quality and performance.

Reliability of the BMW 5 Series Mk7

The reliability of the BMW 5 Series Mk7 undoubtedly reflects its status as a premium executive sedan, blending sophisticated engineering with robust performance standards. Renowned for its solid construction and advanced technology, the 5 Series Mk7 is designed to meet the high expectations of its discerning owners.

Build Quality: BMW’s commitment to quality is evident in the 5 Series Mk7. The use of high-grade materials both inside and out ensures durability and a premium feel. The attention to detail in assembly contributes to the vehicle’s overall reliability, minimizing common issues associated with lesser finishes.

Engine Performance: The 5 Series Mk7 offers a range of powertrains, from efficient 4-cylinder diesel engines to more powerful 8-cylinder turbocharged petrol options, all known for their longevity and low maintenance needs. BMW’s engineering excellence ensures that these engines deliver performance without sacrificing reliability, even under strenuous conditions.

Electrical Systems: This generation of the 5 Series includes advanced electrical systems that support various functionalities, from safety features to infotainment systems. While these sophisticated systems enhance the driving experience, they require proper maintenance to operate effectively over time. Regular software updates and checks are recommended to keep these systems running smoothly.

Common Issues and Maintenance: While the BMW 5 Series Mk7 is a paragon of reliability, like any vehicle, it has its vulnerabilities. Common issues that owners might encounter include electronic component glitches and wear-and-tear on suspension parts. BMW offers comprehensive service packages and extended warranties that cover many potential faults, ensuring that any problems are addressed promptly and without significant expense to the owner.

Regular maintenance and adherence to service intervals are key to ensuring the vehicle operates at its best for many years.

Owner Feedback and Long-Term Ownership

Owner Feedback:

Owner feedback on the BMW 5 Series Mk7 is predominantly positive on forums and online groups trawled for this information, reflecting the model’s strong appeal among executives and car enthusiasts alike. Owners often praise the vehicle for its luxurious interior, smooth ride quality, and precise handling, which make it a pleasure to drive both in city traffic and on the highway. The sophisticated design and state-of-the-art technology features, including the intuitive infotainment system and advanced driver assistance systems, also receive high marks for enhancing the driving experience.

Many owners appreciate the 5 Series Mk7’s blend of performance and efficiency, especially those who opted for the hybrid or diesel models, which offer an excellent balance of power and fuel economy. The spacious and comfortable interior is frequently highlighted as a key factor in the car’s appeal, making it suitable for both family and business use.

Long-Term Ownership:

Long-term ownership of the BMW 5 Series Mk7 tends to be very rewarding, but it requires a commitment to regular maintenance and care. The vehicle’s build quality and engineering mean that it can maintain high performance levels for many years if properly serviced. Key to this longevity is adhering to BMW’s recommended maintenance schedule, which includes regular oil changes, inspections, and the timely replacement of wear-and-tear parts.

However, some long-term owners report higher-than-average maintenance and repair costs compared to non-premium brands, particularly once the vehicle is out of warranty. This is often due to the sophisticated nature of the vehicle’s components and systems, which can be expensive to repair or replace. Despite these costs, many owners find the expense justifiable given the vehicle’s performance, comfort, and driving pleasure.

The resale value of the BMW 5 Series Mk7 remains strong, buoyed by the brand’s reputation for reliability and the ongoing demand for luxury sedans. Owners who keep their vehicles in good condition and follow the maintenance guidelines can expect a favorable return on their investment if they choose to sell.

Overall, owner feedback and experiences with long-term ownership underscore the BMW 5 Series Mk7 as a well-rounded executive sedan that offers luxury, performance, and advanced technology, albeit with considerations for maintenance costs and regular upkeep.

Common Problems with the BMW 5 Series Mk7: Insights from Owner Forums and Expert Reviews

The BMW 5 Series Mk7 (2017 to 2024) is a hallmark of luxury and engineering excellence, but like any vehicle, it is not without its issues. Insights gleaned from owner forums and expert reviews highlight several common problems that potential buyers and current owners should be aware of:

  1. Electronic System Issues: A recurrent theme in owner complaints involves glitches in the vehicle’s electronic systems. These can range from infotainment malfunctions, such as the iDrive system freezing or being unresponsive, to more critical issues like faults in the digital instrument cluster display. Navigation system errors and Bluetooth connectivity problems are also frequently reported.
  2. Engine and Transmission Problems: Some owners have experienced issues with the vehicle’s engine and transmission. This includes sporadic incidents of rough idling, unexpected stalling, and transmission slipping. Although not widespread, these problems can be concerning, especially when they occur unexpectedly on busy roads or during long-distance travels.
  3. Cooling System Failures: Cooling system failures, particularly with the thermostat and water pump, have been noted as a concern in some instances. These failures can lead to overheating, which is particularly risky in high-performance models that depend heavily on effective cooling systems to manage engine temperature.
  4. Suspension and Steering Components: There have been reports of premature wear of suspension components such as bushings and ball joints, as well as issues with the power steering system. These defects can affect the vehicle’s handling and overall driving experience, necessitating early repairs or replacements to maintain ride quality and safety.
  5. Oil Leaks and Consumption: Oil leaks are another issue that some owners have encountered, often related to oil seal failure or gasket problems. Additionally, higher than expected oil consumption has been noted in certain engine variants, requiring more frequent oil checks and top-ups between scheduled services.
  6. Electrical Components and Sensor Failures: Electrical issues, including failures of sensors and actuators related to the vehicle’s safety and efficiency systems, are also among the common problems reported. This includes malfunctioning door locks, faulty fuel gauges, and erratic behavior of parking sensors.

While these issues can pose inconvenience and potential costs, it’s important to note that many owners report these problems as infrequent and manageable with regular maintenance. BMW’s warranty and service programs typically address these issues effectively, and the overall sentiment from owner forums and expert reviews remains overwhelmingly positive, emphasizing the vehicle’s performance, comfort, and advanced features. Prospective buyers should consider these factors in their decision-making process and perhaps opt for an extended warranty or a pre-purchase inspection to mitigate potential concerns.

Price Factors to Consider When Buying a Used BMW 5 Series Mk7

When considering the purchase of a used BMW 5 Series Mk7 (2017 to 2024), several price factors come into play. These considerations not only affect the initial purchase price but also impact the overall cost of ownership. At the time of writing, there were less than 100 to choose from across South Africa’s most trusted used car advertising platforms, with a spread of engine sizes and trims. (NOTE: Remember, these sell in far fewer numbers than BMW’s SUV models.) Here’s a breakdown of key price factors to consider for prospective buyers in South Africa:

  1. Model Year and Condition: The age of the vehicle significantly influences the price. Newer models, especially those closer to 2024, will command a higher price due to their more recent technology and lower mileage. The condition of the car, including both its mechanical and aesthetic aspects, also plays a crucial role. A well-maintained BMW with a clean history and minimal wear will be priced higher than one with significant wear or past accidents.
  2. Mileage: Mileage is a critical factor in pricing used cars. Higher mileage generally lowers the price since it often correlates with greater wear and potential future repairs. However, BMWs are known for their durability, so a well-maintained, high-mileage vehicle might still be a good investment.
  3. Trim Levels and Options: The BMW 5 Series Mk7 comes in various trims, each adding different features and luxuries that can affect the price. Models equipped with higher-end trims like the M Sport or those featuring advanced packages, including premium sound systems, enhanced driver assistance systems, and luxury seating, will cost more. Custom options such as unique interior finishes or advanced technology features also add to the resale value.
  4. Engine Type and Performance: Different engine options can affect the vehicle’s price. Diesel engines, known for their efficiency and durability, might command a premium, especially in markets where diesel is favored. Similarly, the more powerful six-cylinder and hybrid models are usually more expensive than their four-cylinder counterparts due to better performance and, in the case of hybrids, potential fuel savings.
  5. Market Demand and Availability: Local market conditions significantly impact used car prices. In regions where the demand for luxury sedans like the BMW 5 Series is high, prices tend to be higher. Conversely, if the market is flooded with similar models, prices may be lower to stimulate sales.
  6. Ownership and Maintenance History: A vehicle with a detailed service record from certified dealerships is more desirable and often commands a higher price. A history of regular maintenance can assure buyers of the car’s reliability and reduce the risk of expensive future repairs.
  7. Warranty and Service Packages: If the car is still under warranty or includes a transferable service package, this can enhance its value. Extended warranty coverage can be particularly appealing as it provides additional security against unforeseen repairs.
  8. Resale Value: BMW vehicles, including the 5 Series, generally maintain a robust resale value, especially models that are well-maintained and equipped with popular features. This factor can be a double-edged sword, as it means purchasing a used model might be more expensive upfront, but it also suggests potential for a better return on investment when reselling.

When buying a used BMW 5 Series Mk7, it’s wise to weigh these factors carefully. Conducting a thorough inspection, possibly with the help of a professional, and reviewing the vehicle’s history through reports and maintenance records can help ensure that you are making a well-informed decision that balances quality with cost.

Other Vehicles to Consider

When considering a used BMW 5 Series Mk7, it’s useful to look at comparable vehicles in the executive sedan category to ensure you’re making the best choice for your needs and preferences. Here are several alternatives to the BMW 5 Series Mk7 that offer a mix of luxury, performance, and technology:

Mercedes-Benz E-Class: A direct competitor to the BMW 5 Series, the Mercedes-Benz E-Class is renowned for its refined interior, advanced technology, and comfort. It offers a range of engine choices, including efficient diesel options and powerful petrol engines, with a strong focus on luxury and driver assistance features.

Audi A6: The Audi A6 stands out with its modern design, sophisticated all-wheel-drive system (Quattro), and high-quality cabin. It provides a balanced ride with excellent handling and is well-regarded for its innovative technology, including a user-friendly infotainment system and a range of hybrid models.

Lexus GS: Known for its reliability and build quality, the Lexus GS offers a more tranquil cabin and smoother ride compared to some of its German rivals. It features a selection of powerful engines and is especially popular for its hybrid variants, which provide a good balance of performance and fuel efficiency.

Volvo S90: The Volvo S90 is admired for its safety features, spacious interior, and Scandinavian design ethos. It stands out with its comfort-oriented ride and strong focus on safety innovations. The S90 also offers hybrid models that are both powerful and efficient, making it an excellent choice for environmentally conscious consumers.

When exploring these alternatives, consider factors such as performance, comfort, technology, reliability, and total cost of ownership. Each of these models offers different strengths, so selecting the right vehicle will depend on your specific priorities and preferences.

Final Thoughts

The BMW 5 Series Mk7 is a premium choice in the used car market in South Africa for those looking for an executive sedan that offers luxury, performance, and advanced technology. It is a sophisticated vehicle that demands consideration, especially for discerning buyers who are willing to invest in its upkeep for the superior driving experience it offers.
