1991 Bmw 735i problems
The BMW E32 is the second generation of the BMW 7 Series luxury cars and was produced from 1986 until 1994. It replaced the E23 and was initially available with straight-six or V12 powerplants. In 1992, V8 engines became available. From its inception, the E32 was among the most technologically advanced series of cars in its day.
The E32 introduced numerous features including adaptive suspension (EDC), traction control, two available wheelbases (i and iL), and dual-zone climate control. The E32 750i was the first car adhering to "gentlemen's agreement" amongst the German manufacturers limiting maximum speed to 250 km/h (155 mph).
Other automotive passenger vehicles features introduced with the E32 included: projector lens headlamps (1986); double glazing windows (1991); HID (Xenon) headlamps (1991).
E32 also introduced BMW's first V8 engine since the BMW 501/502, last produced in 1962, and their first V12 engine, which was also Germany's first post-war V12 engine for a passenger vehicle.
In 1994, the E32 was replaced by the E38, a clear evolution of the E32.

Common 1991 Bmw 735i problems
The BMW 735i, produced between 1986 and 1994, is known for its sophisticated engine and luxurious features. However, like any vehicle, it has some common issues that owners may encounter.
- Valvetrain: One common issue with the BMW 735i engine is with the valvetrain, specifically the hydraulic lifters. These lifters can fail, resulting in a ticking or tapping noise from the engine. This is often caused by sludge buildup in the engine, which can prevent the lifters from properly pumping up. Regular oil changes and the use of high-quality synthetic oil can help prevent this issue.
- Cylinder Head: Another common issue with the BMW 735i engine is with the cylinder head. The cylinder head gasket can fail, causing oil leaks and overheating issues. The cylinder head itself can also crack, causing similar issues. This can be caused by overheating, which can be prevented by regular cooling system maintenance and attention to any signs of overheating.
- Timing Chain: The timing chain is another component that can cause issues with the BMW 735i engine. The timing chain tensioner can fail, causing the chain to become loose and skip teeth on the timing gears. This can cause serious engine damage, so it is important to address any signs of chain noise or issues with the timing system.
- Oil Consumption: The BMW 735i engine has been known to consume oil, particularly in older models. This can be caused by worn piston rings, valve seals, or other engine components. Regular oil changes and the use of high-quality synthetic oil can help mitigate this issue, but it may also require engine repairs to fully address the issue.
- Electrical Issues: The 1991 BMW 735iL can also experience electrical issues, as detailed in a YouTube video. The video discusses fixing auto transmission shifting issues, lighting issues, cluster issues, replacing a fuel door hinge and tail light, and other electrical problems. These issues can be caused by corroded or dirty electrical paths, which can be cleaned with sandpaper and WD-40 .
In conclusion, while the BMW 735i is a well-regarded luxury sedan, it does have some common issues that owners should be aware of. Regular maintenance, including oil changes and cooling system checks, can help prevent many of these issues. If electrical problems are suspected, cleaning and repairing the affected components can often solve the issue.
