The BMW 3 Series (E90, E91, E92, E93) from 2006 to 2012 is where performance meets practicality—an architect of thrills and a companion for the daily grind. Renowned for its dynamic handling and luxurious amenities, this series stands out as BMW's quintessential sports sedan. Featuring a variety of powerful engines, including the popular 325d diesel, this model offers both outstanding fuel efficiency and driving enjoyment. In New Zealand, its widespread popularity reflects a wise investment in European craftsmanship and performance, making it a go-to choice for those who appreciate the finer things in automotive life. But with great responsibility comes the necessity of understanding what goes into maintaining such an exemplary vehicle.
Common problems include oil leaks (valve cover gasket, oil filter housing), VANOS (variable valve timing) issues, water pump failure, and problems with the direct injection system on the N54/N55 engines. The electrics can also be prone to issues, especially with the iDrive system and window regulators. Suspension components, particularly control arm bushings, tend to wear out relatively quickly on NZ roads.
WOF tips
Pay close attention to tyre condition and alignment, as these cars are sensitive to worn suspension components. Check for oil leaks, as even minor leaks can result in a WOF failure. Rust is less common than on older BMWs, but check the sills and around the windscreen for any signs of corrosion, especially on lower spec vehicles or those that have been poorly maintained. Brakes also tend to be heavily used and expensive to repair due to advanced electronic braking functions.
About the BMW 3 325 d
The E90 generation of the 3 Series boasts a variety of engines—ranging from the economical N46 2.0L 4-cylinder to the robust N55 3.0L twin-turbo inline-6. Among these, the 325d is particularly favored for its blend of torque and efficiency, making it ideal for New Zealand's open roads and urban pursuits. However, like any used vehicle, it's crucial to be aware of what maintenance the car might require. Common replacements include water pumps, which should be inspected around the 150,000km mark along with the thermostat and radiator hoses to keep your cooling system in top shape [Explore our Cooling category for parts].
The rear power windows can be prone to issues—don’t be surprised if you need to check window regulators from time to time. Additionally, oil leaks, particularly from the valve cover gasket, are not uncommon. Regular oil services every 10,000 km can help mitigate further engine issues and ensure that your car remains as spirited as the day you drove it off the lot. For comprehensive maintenance, don’t overlook our Braking and Filtration product categories; these contain everything you need for critical systems in your 325d, from brake pads to air filters that promote operational efficiency. With the right service packs, you can keep your BMW running at its best.
