It is not the engine that tends to grab headlines, but there are a lot of them on UK roads, and if you are buying a used BMW in this part of the range, you will almost certainly encounter one. This guide answers the question that comes up most often: which BMW actually has the B38 engine, and specifically the updated B38TU version? It also covers what you need to know about reliability and what to check before buying, explained simply.  What Is the BMW B38 Engine? Simply put, the B38 is BMW's three-cylinder petrol engine.

They don't wear at a predictable rate regardless of conditions. They wear based on how the car is driven, what pads are fitted, and whether the brakes are used hard or gently. That said, there are sensible ranges to work from and clear signs that tell you when replacement is due.

On a gently driven diesel that does mostly motorway miles, they can reach 80,000. Rear discs Rear discs on most BMWs last considerably longer than fronts, often 70,000 to 100,000 miles under normal use. T...

  Image: BMW 3 Series M Sport LCI multifunction steering wheel for sale at MT Auto Parts for £256.49 Changing the steering wheel on a BMW F30 3 Series is a job most owners tackle for one of three reasons: the original is worn, they want to upgrade to a BMW M Sport or Alcantara wheel , or they're fitting a replacement after an airbag deployment. Whatever the reason, the job itself is straightforward, but two things matter before you start: disabling the airbag system correctly and having the wheel coded after fitting. Before You Start The F30 steering wheel houses the driver's airbag. Before removing the wheel, the airbag system must be disabled. Failure to do this risks accidental airbag deployment, which is both dangerous and expensive. Disconnect the battery and wait a minimum of 15 minutes before working on the steering wheel. This allows the capacitors in the airbag system to discharge fully. Some technicians recommend 30 minutes for added caution. Do not skip this step. ...
