Character

N53

"Direct-injection version of the N52 for Europe only (it needs low-sulphur fuel). It shares the N54 fault list minus the turbos: piezo injectors, the high-pressure fuel pump and the NOx sensor/catalyst are the expensive items, plus oil leaks with age. Buy only with records showing late-index injectors and the pump already done."

S58

"The 3.0-litre twin-turbo straight-six of the X3 M, X4 M, M3, M4 and M2 (2019 onwards). So far it has proved very tough: AUTO BILD stripped a 100,000 km M3 and found almost no wear, no oil use and no breakdowns. The one manufacturing fault was a batch of main bearing shells in cars built July-September 2021, held back by BMW and repaired before delivery. Otherwise expect normal M-car wear items: crankcase ventilation valve, coolant leaks and spark plugs on hard-driven or tuned cars."
