Is the 2.4, 2.8 and 3.0 V6 30v reliable?

The 30-valve V6 engines of the Volkswagen Group (2.4, 2.8 and 3.0) have few documented faults: there are few owner reviews, and they mention coils, the thermostat and oil leaks. The most sensitive item is the timing belt, which on the 2.8 also drives the water pump: Audi and VW ask for it to be changed every 120,000 km, and the job takes 2.9 to 3.5 hours.[1][2][3][4]

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.[5][6][7]
