The Volkswagen BMT – Petrol is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2018. It features direct fuel injection, a single turbocharger, and dual overhead camshafts (DOHC). This engine was designed to balance efficiency with responsive performance, delivering peak outputs around 110 kW (150 PS) and 250 Nm of torque.
Fitted to models such as the Mk7 Golf, Jetta, and Beetle, the BMT – Petrol was engineered for drivers seeking brisk acceleration and good fuel economy in a compact package. Emissions compliance was achieved through technologies like variable valve timing, allowing it to meet Euro 5 and later Euro 6 standards depending on the model year and market.
One documented concern involves potential carbon buildup on intake valves, a known characteristic of direct-injection petrol engines. This issue, referenced in Volkswagen's internal service documentation, can lead to rough idling or reduced performance if not addressed. Regular induction system cleaning is recommended as preventative maintenance.

The turbocharged design provides strong mid-range torque ideal for overtaking but requires premium unleaded fuel (95 RON minimum) to prevent knocking and maintain performance. VW 502 00/504 00 specification oil is critical for protecting the turbocharger and timing chain. Carbon buildup on intake valves is a known characteristic; periodic cleaning (every 60,000–80,000 km) is recommended to maintain smooth idle and throttle response. The timing chain is designed for longevity but should be inspected if unusual noises are detected.
Oil Specs: Requires VW 502 00 or 504 00 specification oil (Volkswagen Owner's Manual). LongLife service intervals permitted with correct oil.
Emissions: Euro 5 certification applies to pre-2016 models; Euro 6 applies to 2016-2018 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under DIN 70020 standards. Output requires 95 RON fuel (Volkswagen TIS Doc. VW-68000).

The Volkswagen BMT – Petrol was used across Volkswagen's MQB platform with transverse mounting. This engine received platform-specific adaptations-including revised engine mounts for the Beetle-and from 2016 received updates for Euro 6 compliance, creating minor software and hardware revisions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat surface of the cylinder block, near the transmission flange (Volkswagen TIS VW-67895). The 8th digit of the VIN typically corresponds to the engine type. Visually, the engine features a plastic intake manifold and a centrally mounted oil filter. Differentiation from other 1.4 TSI variants (e.g., CBFA, CZTA) requires checking the specific engine code stamp or ECU software version. Service parts for pre-2016 (Euro 5) and post-2016 (Euro 6) models may differ, particularly for emissions components.
The BMT – Petrol's primary reliability consideration is carbon buildup on intake valves, a common trait in direct-injection engines. While not always a failure, it can degrade performance. UK DVSA data shows related issues are a factor in some MOT failures for emissions or running faults. Using the correct fuel and oil, along with periodic induction cleaning, is key to long-term smooth operation.
Analysis derived from Volkswagen technical bulletins (2012-2018) and UK DVSA failure statistics (2016-2023). Repair procedures should follow manufacturer guidelines.
