The 1.8 TCe (M5P) in the Alpine A110 and the Mégane R.S. IV has no documented endemic faults. What has been published are recalls for the A110: the oil pressure solenoid valve (2019) and the fuel pump (2021 and 2023).

Which 1.8 TCe versions should you buy?

Our verdict for each version, based on the documented faults.

Buy: No known serious faults, or they have already been corrected, in this version. With caution: Worth buying if something specific is verified: history, a replaced part or a completed campaign. Avoid: High risk of a serious fault that is hard to check for or prevent.

Known faults of the 1.8 TCe

Sorted from most to least important (severity × frequency).

  1. 1High severityFrequency: OccasionalLubricationA110 oil pressure solenoid valve sticking in 2018–2019 carsYes, on early-series A110s. In 2019 Alpine issued a recall because metal particles can jam the oil pump solenoid valve in the high-pressure position. L'argus reports abnormal noise, a “risk of engine failure” warning and, in the worst case, engine failure.
  2. 2High severityFrequency: OccasionalFuelA110 fuel pump that can leave the car unable to start when hotYes. In 2021 Alpine issued a recall for the fuel pump (2,849 A110s in France, built from 1 October 2018 to 4 November 2020), and in October 2023 another one for the same part: in strong heat the car may fail to start or lose power.

What the 1.8 TCe is

The 1.8 TCe (code M5P, “M5Pt” in the Mégane) is a 1,798 cm³ turbocharged four-cylinder with direct injection, derived from Renault-Nissan engines and reworked by Alpine's engineers. It debuted in the Alpine A110 in 2017 and reached the fourth-generation Mégane R.S. in 2018, where it replaced the F4Rt 2.0 turbo of the Mégane II and III R.S.[4][5]

In the A110, with a Getrag seven-speed dual-clutch gearbox, it produces 252 hp (320 N·m). The 2019 A110 S raises this to 292 hp, the A110 R to 300 hp, and the 2024 R Ultime to 350 hp and 420 N·m. In the Mégane R.S. it produces 280 hp (300 hp in the Trophy), with a six-speed manual or automatic gearbox.[4][5][6]

The A110 is built in Dieppe and, according to Wikipedia, production ended in mid-2026. The Mégane R.S., the last Renault Sport model, was discontinued in 2023.[4][5][6]
