  Photo by El Malandro on Unsplash The BMW F30 3 Series is one of those cars you just see everywhere. If it’s a diesel doing motorway miles or a petrol M Sport cruising through town, it has become a proper staple on UK roads. And it’s easy to see why. It looks modern, drives really well, and still gives you that classic BMW feel without being too harsh or too expensive to run (at least on paper). When it came out between 2011 and 2018, it felt like a big step forward from the E90. But now these cars are ageing, and as they move past 70,000–120,000 miles, certain patterns start showing up. Not every car has issues, but after seeing and dealing with plenty of them, you do start noticing the same things again and again. The F30 is a great car… but the engine choice changes everything This is probably the most important thing to understand with the F30. Two cars can look identical on the outside, but underneath, they can behave completely differently depending on the engine. For exampl...

When the N47 diesel developed a reputation for catastrophic timing chain failures, chains snapping at the back of the engine, behind the flywheel, turning reliable diesel cars into very expensive paperweights, BMW went back to the drawing board. The B47 engine arrived in 2014. It moved the timing chain to the front of the engine, where it belongs. It improved fuel efficiency. It met Euro 6 emissions standards. And it built a reputation as one of the better modern diesel engines in its class. That reputation is mostly deserved. But the B47 is not without its own problems, and some of them are serious enough that anyone buying a used car with one fitted should know about them before handing over any money. This guide covers what actually goes wrong, when, and what it costs to fix. What the B47 Is and Where It's Fitted The B47 is a 2...

  Image: BMW 3 series hybrid automatic gearbox for sale at MT Auto Parts for £1,981.22 Short answer: yes. Very. With one important condition attached. BMW automatic gearboxes, specifically the ZF-made units that have been in virtually every automatic BMW since 2009, are among the most highly regarded gearboxes in the industry. They've been fitted to over 35 million vehicles worldwide across more than 20 manufacturers. Rolls-Royce uses one. So do Bentley, Aston Martin, and Land Rover. When an automatic gearbox is the choice for cars that cost £300,000, that tells you something about the engineering. The condition is fluid maintenance. BMW describes the gearbox fluid as 'lifetime fill'. ZF, the company that actually makes the BMW gearboxes , recommends changing it every 50,000 to 75,000 miles. These two positions have caused more BMW gearbox failures than any design flaw. Listen to BMW and ignore it, potentially fine for 100,000 miles, then erratic shifting and accelerated in...
