Is the 1.3 TCe reliable?

The 1.3 TCe / 1.3 DIG-T (H5Ht at Renault and Dacia, HR13DDT at Nissan, M282 at Mercedes-Benz), developed with Daimler since 2018, has a clearly better record than its predecessor, the 1.2 TCe: no oil consumption or chain problems have been documented. It had manufacturing defects that have since been corrected (injectors, calibration, turbo, timing) and, on the Captur II and Clio V, a fuel pump fuse failure with no confirmed official fix.[1][2][3]

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.[4][5][6]
