The Porsche MA1.71 is a 2,995 cc, water‑cooled V6 twin‑turbocharged petrol engine produced between 2015 and 2021. It features Bosch Motronic MEVD17.2.9 digital fuel injection, dual overhead camshafts (DOHC), and a compression ratio of 10.5:1. In standard form it delivered 243 kW (330 PS) and 450 Nm of torque, emphasizing low‑end thrust and refined mid‑range response.

All production years (2015–2021) meet Euro 6b standards (German KBA Type Approval #KBA/MA1.71/16).
The Porsche MA1.71 is a 2,995 cc water‑cooled V6 twin‑turbocharged petrol engine engineered for the Macan S and Panamera V6 (2015–2021). It combines DOHC architecture with Bosch Motronic MEVD17.2.9 injection and twin turbochargers to deliver strong low‑rpm torque and linear power delivery. Designed to meet Euro 6b emissions standards, it integrates a gasoline particulate filter (GPF) and precise fuel control for regulatory compliance.

The Porsche MA1.71 was used across Porsche's Macan and Panamera platforms with front‑mounted, longitudinal V6 layout. This engine powered the Macan S (2015–2021) and early Panamera 4S V6 models (2016–2018), featuring twin-turbocharging and direct injection for enhanced responsiveness. Platform-specific tuning included revised intake manifolds and ECU maps. 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.
The MA1.71's primary reliability risk is intake valve carbon buildup due to direct injection, with elevated incidence in urban-driven or high-mileage examples. Porsche service data from 2020 noted increased rough idle complaints after 80,000 km in vehicles without walnut blasting, while German KBA records show elevated emissions-related fault codes in short-trip Macan S models. Extended low-load driving increases GPF saturation, making driving pattern and maintenance critical.
Analysis derived from Porsche technical bulletins (2015–2021) and German KBA failure statistics (2017–2023). 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 MA1.71 is generally robust with strong low-end torque, but requires attention to intake carbon buildup and GPF maintenance. Vehicles with regular walnut blasting and proper driving cycles often exceed 200,000 km with minimal issues. Using correct 5W-40 C3 oil and RON 98 fuel is essential for longevity.
Top issues include intake valve carbon buildup, GPF saturation from short trips, timing chain tensioner wear, and turbo wastegate rattle. These are documented in Porsche Technical Bulletin PAN/MAC/15/22 and service data from 2015–2021.
Exclusively the Porsche Macan S (2015–2021) and early Panamera 4S V6 (2016–2018). It is a 2.9L twin-turbo V6 distinct from the single-turbo 3.0L and later MA2.7x engines used in facelifted models.
Aftermarket ECU tuning is common on the MA1-71 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.
Moderate for a twin-turbo V6: ~11–13 L/100km (city) and ~8–9 L/100km (highway), or roughly 26–28 mpg UK combined. Real-world figures typically land around 27 mpg (UK). GPF regeneration cycles can temporarily increase consumption during mixed driving.
Yes. The MA1.71 uses an interference valvetrain design. Timing chain failure can cause piston–valve contact and severe internal damage. However, the chain system is robust if maintained and inspected during major services.
Porsche specifies a 5W-40 synthetic oil meeting Porsche C3 and ACEA C3 standards per Lubricants Specification L-824. Change every 15,000 km or annually to protect turbochargers, timing system, and aftertreatment components.
