The BMW E32 750il, a flagship luxury sedan of the late 80s and early 90s, remains a sought-after vehicle for its powerful V12 engine, sophisticated engineering, and timeless design. However, owning and maintaining this automotive icon requires understanding its unique complexities. This guide provides insights into the E32 750iL, covering common issues, maintenance requirements, and the benefits of joining the passionate community surrounding this classic BMW.
E32 750iL: A Robust but Complex Machine
The E32 750iL boasts a robust build quality, surpassing even its successor, the E38. However, its advanced features, particularly the M70 V12 engine and the self-leveling rear suspension (LAD), introduce specific maintenance considerations.
The Mighty M70 V12: Dual Redundancy and Potential Trouble Spots
The M70 engine, a marvel of engineering, is designed with redundancy in mind. It can operate smoothly even on a single bank of cylinders in case of a major fault. This impressive capability stems from its dual architecture: two throttle bodies, two fuel pumps, two fuel filters, two fuel regulators, two distributors, and two coils. While this redundancy ensures reliability, it also means double the components requiring maintenance. A common issue with the M70 is the throttle bodies, which can develop problems if not cleaned regularly. Fortunately, reconditioning them is a DIY-friendly task with the right tools.
Self-Leveling Suspension: Keeping it Level
The E32 750iL’s self-leveling rear suspension, known as LAD, enhances ride comfort and handling. However, it can be a source of potential issues. Leaky shocks and worn accumulators (one per rear wheel) are common problems that require attention.
Essential Maintenance for the E32 750iL
Routine maintenance is crucial for preserving the E32 750iL’s performance and longevity. While seemingly simple, these tasks are vital for this complex machine.
Fluids and Filters: The Lifeblood of Your BMW
Regular oil changes for the engine, differential, and transmission are paramount. Maintaining clean brake fluid and coolant is equally critical, requiring flushes at recommended intervals. Neglecting these fundamental maintenance tasks, often overlooked in other car brands, can lead to significant problems in the E32.
Beyond the Basics: Addressing Age-Related Issues
Beyond regular fluid and filter changes, the E32 750iL, given its age, may require attention to specific wear items. Driveshaft and center bearing replacement, along with front-end suspension work, are common tasks due to age-related wear and tear. While these repairs can be more challenging, online resources and a Bentley manual provide invaluable guidance for DIY enthusiasts.
Joining the E32 Community: A Wealth of Support
The E32 community is remarkably large and active, exceeding even those of Volkswagen and Mercedes-Benz. This passionate network provides a wealth of knowledge and support for owners, offering assistance with troubleshooting, maintenance advice, and parts sourcing.
Conclusion: Embracing the Legend
The E32 750iL offers a unique driving experience, blending luxury, performance, and a touch of automotive history. While ownership comes with specific maintenance requirements, the rewards of driving and preserving this iconic BMW are well worth the effort. The supportive community and readily available resources ensure that maintaining an E32 750iL is a manageable and enjoyable experience for dedicated enthusiasts. Understanding the car’s nuances and committing to regular maintenance will allow you to fully appreciate the legend that is the E32 750iL.
