A turbo actuator fault and a failed turbocharger are not the same thing, and confusing the two is one of the more expensive mistakes a BMW owner can make.

Two generations later, the F32 (2013–2020) and the G22 (2020 onwards), there is now a reasonable spread of used examples on the UK market at various price points. Which one to buy comes down, more than almost anything else, to which engine is under the bonnet. Here is an honest comparison of every significant engine option across both generations. F32 BMW 4 Series (2013–2020) — Engine by Engine N20 — the one to avoid The N20 2.0-litre petrol went into the early F32 420i and 428i. It is not a terrible engine, but it has a known timing chain problem that has affected enough owners to give it a poor reputation in the BMW community. The chain and its plastic guides can wear and crack, particularly on cars that have been run on extended oil change intervals. The symptoms, a rattle at cold start that clears after a few seconds, are easy to miss ...

  Photo by Shooting Tyre on Unsplash  There is only one BMW road car engine with ten cylinders. One. The S85. BMW built it between 2005 and 2010, fitted it to exactly four models, and then never made anything quite like it again. The engines that followed were turbocharged, smaller, and objectively faster in many situations. None of them sounds like this.
