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 Porsche MA1 / 9A1 reliable?

Yes, it is noticeably more reliable than the M96/M97: it eliminated the intermediate shaft with its IMS bearing and, according to FCP Euro, the connecting rod bolt failures. What is documented is minor: carbon build-up on the intake valves caused by direct injection, coolant pump leaks on the 991.1 and, rarely, bore scoring on the 997.2.[4][5][6][7]
