Timing drive

Chain, confirmed by ADAC. BMW’s Bx8 training document describes a two-part drive on the transmission side — a lower chain drives an intermediate shaft, which passes the drive to the upper camshaft chain — plus a separate chain for the oil/vacuum pump and spring-preloaded hydraulic tensioners; the inertia of the transmission reduces the loads on the chain. The sources consulted give no replacement interval.

What changed over the years

2014: BMW introduces the Bx8 family; its June 2014 training document describes the B46 variant of this four-cylinder (X1, 231 hp and 350 Nm, 11:1 compression). 2018: the B48B20B of the F30 330i gains a gasoline particulate filter and meets Euro 6d-TEMP (ADAC). 2019: the B48A20T1 of the M135i xDrive, presented by BMW as its most powerful four-cylinder, gets a reinforced crankshaft drive with a larger main bearing, new pistons with altered compression ratio, unbushed con rods, a larger turbocharger with integrated manifold (exhaust temperatures up to 1,025 °C) and higher-flow injectors.
