Bmw 5 Series E28 – The BMW 5 Series roundup continues today with the 5 Series E28. Evolution instead of revolution. The 5-series of the 2nd generation differed optically from the first generation only at first glance. But the most interesting is what’s going on under the chassis. Many technological improvements characterize the second generation BMW 5 Series.

It replaced the E12 and was originally produced with 4- and 6-cylinder petrol engines. In 1983, a diesel engine was available for the first time in the 5 Series.

The launch model was the 528e in 1982, followed by the 533i. [citation needed] The optional automatic was originally a 3-speed (there was a 4-speed automatic in Europe at the time), a 4-speed automatic became optional in 1983. The 524td was only imported with an automatic transmission and the M5 was imported with manual only.

All 1985 North American models had ABS brakes as standard. Electric front seats became a standard feature in 1986. [citation needed] North American spec cars are extensively equipped with standard features such as power windows, central locking, air conditioning, electric sunroof, cruise control, alloy wheels and fog lights.

Instead of importing the M535i, BMW North America created the 535is. [Citation needed] This model is based on the 535i plus front and rear spoilers, sports suspension and sports seats. The BMW E28 5 Series was one of the most beautiful cars ever. That was in the 1980s and today it remains a fantastic driver-oriented sports car. Here’s how to make a great purchase

When launched 35 years ago, the new BMW E28 5 Series was identical to the revamped BMW E12 5 Series, which had been on the market since 1972. – Hot Rod Sedans 518 to 528i and M535i.

Released in September 1981, the E28 5 Series, known by the engine code M10, produced 90 hp. It started with the four-cylinder 518. Next in line is the 518 with optional five-speed gearbox and power steering, followed by the 125 l.h. 150hp M20 520i and M30 525i and 184hp M30 528i with standard alloy wheels, all with five-speed and six-cylinder PAS. and electric windows. A three-speed ZF automatic transmission was optional on all six-cylinder cars.

Rust In Peace: Bmw E28

1981 was a year before the introduction of progressive design cars like the Ford Sierra, so the E28 looked a bit dated when it was introduced. But BMW’s modern rival, the Mercedes W123, was similarly traditional.

The E28 had a distinct BMW personality and was well proportioned and detailed inside and out. Although similar to the E12, very little of the bodywork is carried over: the headliner, the doors (with modifications) and the front and rear windows.

The suspension and brakes have been completely overhauled, nowhere else, the chassis and internal fenders have all been revised with different intake points. The interior was also completely new, with a new “Service Indicator” system which later replaced it on other BMWs.

In late 1982, the 520i received the new E30 3 Series M20 engine with updated cylinder head and LE Jetronic; With the exception of the “dogleg” Sport models, which kept the old unit, all six-cylinder M30s were gradually introduced with the new Getrag 260 gearbox.

For 1983 came the economy-oriented 525e. Using a long-stroke version of the 2.7-liter 520i engine, the “Eta” unit developed 125 horsepower but loads of torque. It was equipped with a new four-speed automatic transmission (similar units were gradually added to other E28 cars in 1983) and the 525e was equipped with long leg gears and an extra long final drive which provided excellent economy and was possible at 35 -40 mph. . long-lasting work.

In September 1984, the E28 underwent a small overhaul. The front edge has been made deeper and rounded, the 528i’s 14-inch 195/70 tires are standard on models previously fitted with thinner sections, and the final gear ratios have been revised. In early 1985, two new models went into production, the 518i and 535i.

The 518i garnered a large number of 520i sales and was quick enough to compete with the 2.0-liter Ford Granada, 1.8-liter Vauxhall Carlton and other larger-engined sedans. The 535i was available in two variants, the plastic body kit (bumpers, sills and rear ends) and the M535i with custom metric wheels and a metal bumper version similar to most other models but with the same wheels and rear ends customized. Both models had Bilstein shock absorbers and M Technic suspension.

The M535i was the most popular model; The version with metal bumper has been discontinued but remains available for special orders and is called the 535i SE. Both were available with Sport, overdrive or four-speed automatic transmission. Luxury versions of the 518i, 520i and 525e were introduced in late 1986. These included velvet upholstery, 14-inch cross-spoke BBS alloy wheels (or optional metric wheels), double side stripes, power windows, manual sunroof and three-spoke leather steering wheel.

SE versions of the 528i have been available for several years; equipment includes four power windows, electric sunroof, metric alloys with TRX choke, headlight washers, trip computer, leather-wrapped steering wheel, limited slip differential on some models (especially cars), large stripes and green paint. a glass.

Production of the E28 5 series ended in December 1987, after a final push to get sufficient stock in early 1988. In the UK, the E28 was officially replaced in June 1988 by the E34, which went on sale in Germany since March.

In addition to regular oil and filter changes, annual coolant changes are required to keep E28 Series 5 engines in good condition. While the M10 and M30 engines require replacement of the oil spray bar banjo bolts, all have adjustable caps that should be checked every 10,000 miles. They were known for their well-functioning hunger and fat cure; BMW now sells replacement banjos with a slightly different crazy string height. Never use the gearbox lock as it coagulates in the oil hole.

Note that the new M30 cams are BMW only at this time, and that’s before adding the twelve new rockers. The M10 and M20 cameras aren’t far behind, so be careful with the noisy E28 camera.

Many things can cause overheating – a damaged viscous fan will cause it to overheat at low speeds, so old-looking clutches should be replaced. The M20 520i and 525e heads can explode with oil and coolant mixtures, but the M30 units have had frequent head gasket problems, mainly due to worn head water passages.

The cylinder heads are different on both cars; The 520i head code is 731, the 525e (and early 520i) head code is 200 and the 525e has four cam bearings that are open only for oil supply.

The M20 engines also used 17mm head bolts and broken heads were not uncommon but not unknown. These can stick to the camera and cause a lot of damage, but it’s easy to remove the camera cover and remove the 17mm bolts (one at a time in the correct order) and replace them with torx head expansion bolts.

518 / 518i engines can suffer from cam gears, similar to a noisy timing chain, but heavily worn; these can easily be replaced with a new, stronger tension spring.

M20 engines have a cam belt that needs to be replaced with a new tensioner every 30,000 miles. It is also necessary to replace the cam oil seal and the water pump. Broken manifold studs are common and difficult to remove, and cracked manifolds produce a noticeable “screeching” sound.

The fuel injection systems for the BMW E28 5 Series vary from vehicle to vehicle. The 518i, 520i, 525i and 528i all used Bosch LE Jetronic, a nice system with few clamps as long as the connections are kept clean and dry; The only known issue is the seven-pin relay that controls the fuel pump and injectors. It’s nice to have a spare in the car.

The 525e and 535i use the Bosch Motronic 1.1 system. These were very good, but they have some problems with aging; the fuel pump and DME relays cause the same intermittent or intermittent fault, the two flexible position sensors from a small pin on the flywheel (which can fall out), and a faulty ECU. Replacement drives for these should be sought out as they are often not available and are not replaced by Bosch.

The pre-1984 three-speed automatic is nearly indestructible, but the four-speed 4HP22 isn’t that great. A good way to kill one is to shift into neutral or park and partially start due to cross leaks from the oil pump to the front clutch due to age and wear. If you start the engine, you will burn the clutch plates that do not advance.
