1993 Bmw 740 problems
The BMW E38 is the third generation of the BMW 7 Series luxury cars and was produced from 1994 until 2001. The E38 replaced the E32 7 Series and was produced with petrol and turbo-diesel straight-six and V8 engines, along with a petrol V12 flagship model.

Common 1993 Bmw 740 problems
The BMW 740i from 1993 is known to have several common problems based on complaints from owners. One of the most significant issues is related to the engine, specifically the Nikasil V8 engines used in 1993-1995 models. The Nikasil engine block material reacts with sulfur in U.S. fuels, causing rough idling, stalling, and eventually piston failure due to cylinder bore damage. BMW addressed this issue by replacing affected Nikasil engine blocks with Alusil engine blocks, which are not sensitive to sulfur in U.S. fuel. However, if a 1993 BMW 740i has the original Nikasil engine, it may have already experienced some damage before sulfur levels in American gasoline were reduced in 1998.
Another common problem with the 1993 BMW 740i is the clutch and fan system. The clutch can fail, preventing the fan from producing enough airflow to cool the engine. This issue is particularly noticeable when the car is stationary, and the fault may be indicated by warning messages related to the cooling system.
The E32 7-Series, including the 740i, is also known to suffer from the "dreaded shimmy," a wheel-wobble that usually occurs under braking or when accelerating through 50-60 MPH. This issue is often an indication of general wear in the steering system and suspension and can be caused by the BMW E32's heavy weight over the front wheels, especially when braking. The shimmy can be repaired, but it may require addressing weaknesses in the steering and suspension system.
Additionally, the cooling system in the 1993 BMW 740i is known to have weaknesses, particularly in the radiator. The plastic body of the radiator can crack around the top hose connection, causing a weep around the hose that is difficult to trace. This issue is often indicated by white marks down the side of the radiator.
Finally, the external lighting system in the 1993 BMW 740i can be prone to faults, including false bulb failure messages and issues with bulb contacts. These issues can be caused by corrosion on the bulb-contacts and may require cleaning or replacement to resolve.
In summary, the 1993 BMW 740i is known to have several common problems, including engine issues related to the Nikasil V8 engines, clutch and fan system faults, the "dreaded shimmy," cooling system weaknesses, and external lighting system faults. Owners of this vehicle should be aware of these issues and consider regular maintenance and inspections to address potential problems before they become serious.
