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 BMW N54/N55 reliable?

The N54 (2006-2016) is a 3.0-litre twin-turbo straight-six with many documented faults: high-pressure pump, injectors and wastegates. The N55 (2009-2019) uses a single turbo and is considered simpler, although it shares oil leaks from the filter housing and the electric water pump.^[4][5][6][7]
