DIY repair and maintenance of BMW 1 series

Engine

  • Increased motor oil consumption is a common issue for N46 power units after 100,000 kilometres. In most cases, the problem is solved by valve stem seals replacement. You can handle this yourself only if you have relevant experience and suitable equipment.
  • High-performance engines tend to overheat, which leads to cylinder head damage. To avoid this problem you need to control the engine temperature, as well as coolant level and its quality. You can easily replace the coolant yourself if you study our illustrated PDF manual on BMW 1 series repair.
  • On cars equipped with the N43 engine, the timing chain may wear out early. Our recommendations: do not ignore scheduled inspections, do not use a vehicle with a stretched chain, check its tensioning regularly.
  • Fuel injectors may fail after 80,000 kilometres. They should be replaced at a service station. Use only high-quality fuel as a precaution.
  • The 1.6-litre petrol engine is notorious for starting problems in the cold season. Moreover, this engine has unstable idling at subzero temperatures. Try to store the car in a warm garage in winter.

Transmission

  • Jerky shifting may occur in cars with an automatic transmission. It is impossible to address this issue yourself – most often the electronic control unit needs a software update. Visit a service station.
  • The torque converter and mechatronic unit may fail quickly in the ZF automatic transmission. They are sensitive to the quality of ATF. Replace it within the intervals specified by the vehicle manufacturer and follow the procedure you’ll find in our step-by-step BMW 1 series repair and maintenance manual. To replace defective components seek professional assistance.

Interior

  • A factory-installed audio system receives radio signals erratically. You can visit a service station for its diagnostics and adjustment or buy a new device. You will install it easily after watching our BMW 1 series DIY repair and maintenance video tutorial.
  • The steering wheel position adjustment mechanism is not as reliable as you would like. When it fails, the whole unit should be replaced. You’ll need to visit a car service station to get this job done.
  • Door seals do not last long as well. Moisture and dust from the outside will get inside the car if you don’t replace them in time. You can install new seals yourself. Before you start working, download our step-by-step video tutorial on BMW 1 series repair for free.
