Everything You Need to Know About the BMW 7 Series E32 - Fault Guide

Salon 7 corresponds to the class of the car. All interior details are made very high quality and carefully fitted, and finishing materials stand the test of time well. The only weak point is the lateral support of the pilot seat, which gradually wears out. It is very spacious inside, and it is comfortable to sit in the back even cross-legged. The gallery of the elongated version of the car generally implies a lot of free space, contributing to comfort inside the seven. In terms of good sound insulation, the trunk volume is impressive at 500 liters, but it has a large loading height.

Engines: The line of power units consists of only five gasoline engines. In-line sixes of the MZO family with 3.0L and 3.5L, V8 of the new M60 family with 3.0L and 4.0L, and a 12-cylinder unit with a volume of 5.0 liters. According to Burger standards, the 5.0-liter engine is disposable and cannot be repaired, but domestic Craftsman Menders have managed to repress the cylinder block with cast iron liners, and after that, they make a capital cars. Those equipped with 5.0-liter engines, as a rule, are heavily worn, and such units often have oil leaks, especially from under the crankshaft rear oil seal, valve cover, and oil pan. The 60 V8 engines are very demanding on fuel quality. In addition, they often leak oil from under the valve cover gasket. When choosing a seventh, experts recommend giving preference to specimens equipped with MCO Motors as they are more reliable, although they need to adjust the thermal clearances of the valves. Other units do not require this procedure. The reason for overheating of engines is the failure of the viscous coupling of the cooling system fan.

Transmission: All 750s were equipped only with automatic gearboxes. The first years of production had a 4-speed, later 5-speed, and weaker versions both automatic and 5-speed manual. All gearboxes are reliable and able to last long enough. However, in the mechanics, over time, the oil seal of the gear shift and the rear oil seal of the gearbox may lose tightness, as well as the input shaft seal in automatic machines with a run of more than 250 to 300,000 kilometers. The gasket of the oil pan can leak.

Running the chassis of the seven is almost the same as the five, but due to the greater weight of the limousine, its service life is somewhat shorter. Ball bearings are supplied only assembled with front suspension arms and withstand about 50,000 kilometers. The silent blocks of these levers live for about the same amount. Racks of the front anti-roll bar can go out at about forty thousand kilometers. The rear suspension also needs maintenance. Every sixty thousand kilometers, you need to change the silent blocks of the rear beam. On vehicles older than 10 years, anti-roll bars wear out.

The most expensive versions were equipped with rear air suspension equipped with an automatic ride height maintenance system depending on the axle load. On cars with high mileage, problems can arise with it, and repairing such a suspension will be expensive.

Steering: The steering of all sevens is equipped with a hydraulic booster with a variable degree of gain. The weakest points of the helm are tie rod ends, which wear out between 40,000 to 60,000 kilometers. After 10 years of operation of the car, play often occurs in the steering gear.

Brake system: Thanks to the use of disk mechanisms as well as the ABC system, the brake system is very effective. The brakes of the seven can be equipped with vacuum and hydraulic boosters. Over time, malfunctions of the hydraulic accumulator of the brake system were noted. Due to the failure of the anthers, the calipers can wedge, which is a fairly common malfunction of cars equipped with an automatic non-working parking brake.

Due to high mileage, many BMW 7 Series e32 can require serious repair costs, and the cost of maintenance and spare parts corresponds to less, even today it is quite high.
