The Porsche MCE.YA is a 2,999 cc, water‑cooled inline‑four turbocharged petrol engine produced between 2020 and 2024. It features dual overhead camshafts (DOHC), 16 valves, direct fuel injection (DFI), and variable valve timing (VarioCam). In standard form it delivered 221 kW (300 PS) at 5,600 rpm, with peak torque of 400 Nm from 2,300 to 4,500 rpm.
Fitted exclusively to the Porsche Macan (95B) S variant in global markets, the MCE.YA represents Porsche’s adoption of a hig…
Production years 2020–2022 meet Euro 6d-TEMP; 2023–2024 models meet Euro 6d .
The Porsche MCE.YA is a 2,999 cc inline‑four DOHC turbocharged petrol engine engineered for performance SUV applications (2020–2024). It combines direct injection, a twin-scroll turbocharger, and variable valve timing to deliver strong low-end torque and refined response. Designed to meet Euro 6d emissions standards, it balances efficiency with sporty character in the Macan platform.

The Porsche MCE.YA was used exclusively in Porsche's Macan (95B) platform with longitudinal front-engine mounting and no external licensing. This engine replaced the 3.0L V6 in the Macan S from 2020 onward, offering lower weight and improved emissions. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from Porsche technical bulletins (2020–2024) and owner association failure logs (2022–2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The MCE.YA offers strong performance and efficiency but early 2020–2021 units carry HPFP cam lobe wear risk under low-RPM lugging. Later models include hardened cams. With proper 5W-40 C4 oil, avoidance of frequent short trips, and highway driving for GPF regeneration, it can be dependable.
Top issues include HPFP cam lobe wear, turbo wastegate rattle, GPF clogging, and cold-start chain rattle. These are documented in Porsche service bulletins. Urban driving without highway intervals accelerates GPF and cam issues.
Exclusively the 2020–2024 Porsche Macan S (95B), where it replaced the 3.0L V6. It was never used in the Cayenne, Panamera, or 911—only the Macan platform as a turbo inline-four performance option.
Aftermarket ECU tuning is common on the MCE-YA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Approximately 11–13 L/100km (22–26 mpg UK) in mixed driving. Highway cruising can reach 8.5 L/100km (33 mpg UK), while urban use exceeds 15 L/100km due to turbo lag and GPF regeneration cycles.
Yes. The Porsche MCE.YA is an interference engine. If the timing chain fails or jumps, pistons will contact open valves, causing severe internal damage. Regular oil changes and tensioner inspection are essential.
Porsche specifies 5W-40 synthetic oil meeting Porsche C4 standard. This ensures cam lobe and HPFP drive protection under high-load stress. Change intervals should not exceed 15,000 km or annually.
