Brief History of the BMW 3 Series & Durability

The first generation of the 3 series was introduced in 1975. It has gone through the following generations:

  • The first generation’s E21 in 1975 which succeeded the 2 series.
  • The second generation’s E30 in 1982. This introduced convertibles and all-wheel drives. The E30 platform was the one on which the first M3 was built. The same platform inspired the BMW Z1 roadster.
  • Third generation’s E36, BMW expanded this line’s body options. It included the hatchback on top of the others. The E36 was also the first in the series to offer a 6-speed manual transmission, a 5- speed automatic transmission and a four-cylinder diesel engine.
  • The fourth generation E46 which came with a bunch of electronic s including Sat-Nav, EBD and rain-sensing wipers.
  • The fifth generation E90s which introduced the run-flat tires meaning they had no need for spares.
  • The 3-series F30s came around in the sixth generation and with them came the Gran-Tourismo. It was also the 3 series that had turbocharged engines for the whole generation. In 2016, a plug- in hybrid drivetrain was put into the 330e model.
  • The 7th generation came out in 2018 in the G20/G21, which has a whole host of impressive new high-tech additions. Based on the Cluster Architecture (CLAR) platform, it also has a multi-link rear suspension and a hydraulic damping system, which absorbs impacts better.

Not forgetting the much-celebrated production from BMW’s performance factory M. The M3 is the 3- series’ most impressive showing and one that can boast wins in Motorsports and still look and feel like a luxury car.

The fact that you can still find some second and third-generation 3-series vehicles in the street speaks volumes about their durability. You wouldn’t keep a model for this long if it wasn’t reliable. Having said that, no car is perfect. We will now look at some issues that you can expect from the 3 series.

Common Issues Affecting the BMW 3 Series

It is obvious with any BMW overheating will become a problem for you at some point. If the car does start to overheat, you best not continue driving and have it towed.

This issue could be a result of a leaking coolant or a faulty water pump. BMW’s valve cover gasket wears down by the time you get to about 70 000 miles so much so that it can start to leak causing the smell of burning oil.

At 75 000 miles, if your steering vibrates as you are braking there is a problem with your thrush arm bushing. These rubber components are important to your suspension system and need looking into should this start occurring.

Maintaining Your BMW 3 Series

The 3-series is a quite reliable BMW line. It has its misfires but overall it is a long-lasting vehicle. To make sure it can keep for longer so to speak, you need to stay on top of any service the car might need.

Make sure to take the car into the shop every time the check engine light comes on. Having the cars oil changed at least once a year and having the wheels rotated twice a year are key.

The battery for a BMW lasts about 3-5 years after which a replacement is necessary. The same goes for the tires as well. As your car gets up to 100k miles, using a synthetic high-performance oil specifically for older does serve your engine. It also ensures you’ll use the car for longer.
