The BMW 3 Series (2009-2012), part of the acclaimed E90/E91/E92/E93 generation, continues to set the standard for sports sedans, particularly in New Zealand. Celebrated for its impeccable handling and exceptional diesel engines, the 320d remains a top choice for discerning buyers. However, as these vehicles age, a careful approach to maintenance is essential. Our comprehensive guide sheds light on vital considerations for New Zealand drivers looking to invest in or maintain their 320d, ensuring it continues to deliver the thrilling performance it's known for.
Common issues include oil leaks (valve cover gasket, oil filter housing), coolant leaks (water pump, expansion tank), Vanos solenoid problems (affecting engine performance), and issues with the electrics. The automatic transmission can also experience problems. Be aware that N47 diesel engines had timing chain issues, whereas the N57 diesel is a little more reliable.
