The BMW 4 Series (2015-2020) (F32/F33/F36) offers a sleek and stylish alternative to the 3 Series, providing a sportier aesthetic and a more focused driving experience. Available as a Coupe, Convertible, and Gran Coupe (four-door coupe), the 4 Series caters to a variety of tastes. However, like any performance-oriented vehicle, it requires diligent maintenance, especially as these cars age.
Common problems with the 4 Series can include timing chain issues (especially on early models with specific engines), oil leaks from the valve cover gasket and oil filter housing, and electrical glitches. The convertible roof mechanism in the F33 can sometimes experience issues, requiring costly repairs. Worn suspension bushes are also a common headache, particularly at WOF time.
WOF tips
Pay attention to tyre wear, especially on models with staggered wheel setups and M Sport packages. Check for brake wear, as the 4 Series can be driven hard. Ensure all lights are functioning correctly, including the often-complex LED headlights. Suspension components and any signs of leaks are a key aspect of the WOF. Be sure to have no tinting on the front windows as this is an easy failure.
About the BMW 4 420 d
The 4 Series shares many mechanical components with the 3 Series, including a range of powerful and efficient engines (both petrol and diesel). Its sportier suspension setup delivers sharper handling, while the interior combines typical BMW refinement with a driver-focused design. The Gran Coupe offers added practicality, with a larger boot and rear accessibility - these are very popular in NZ as they provide a sportier alternative to a traditional wagon or sedan.
