Is the M43 1.6, 1.8 and 1.9 reliable?

The M43 (1993-2002) is an 8-valve petrol four-cylinder with a timing chain that Autohints describes as one of BMW’s most durable engines of the nineties. The faults the sources cite are with ancillaries: plastic cooling parts, oil leaks from the gaskets, rough idle, ignition and, in some versions, the DISA valve.^[1][2][3]

See the 5 of the M43 1.6, 1.8 and 1.9 faults

Is the 1.0, 1.4 and 1.6 8v EA111 reliable?

Eight-valve petrol engines, simple, with a timing belt. For the European 1.0 and 1.4, sources only record isolated incidents, mainly ignition faults in damp weather on the 1.4. In Brazil, the 2008-2010 1.0 VHT of the Gol, Voyage and Fox suffered lubrication-related noise, an oil campaign with extended warranty and a software recall in 2009.^[4][5][6][7]
