The Volkswagen CLNA is a 1,968 cc, inline‑four turbo‑diesel engine produced between 2015 and 2020. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 110 kW (150 PS) and 340 Nm of torque, engineered for responsive low‑end pull and efficient highway cruising.
Fitted to models such as the Mk7 Golf, Mk2 Tiguan, and Passat B8—including the 2.0 TDI 150 variants—the CLNA was desig…
Production years 2015–2020 meet Euro 6 standards across all markets (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CLNA is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2015–2020). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 6 standards, it balances everyday performance with economy.

The Volkswagen CLNA was used across Volkswagen's Mk7/B8 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—revised engine mounts in the Tiguan and modified exhaust routing in the Passat—and from 2018 the facelifted Golf adopted minor ECU and AdBlue tank revisions, creating minor calibration limits. Group partnerships enabled use in Škoda and SEAT models with identical core architecture. All adaptations are documented in OEM technical bulletins.
The CLNA's primary reliability risk is high-pressure fuel pump (HPFP) failure, with elevated incidence in regions with marginal diesel quality or extended oil intervals. Volkswagen internal field data (2018) indicated a measurable uptick in HPFP replacements before 100,000 km under such conditions, while UK DVSA MOT data shows SCR/AdBlue system faults as a growing cause of emissions-related advisories. Use of non-compliant fuel or oil makes adherence to VW 507 00 specification and AdBlue maintenance critical.
Analysis derived from Volkswagen technical bulletins (2015–2020) and UK DVSA failure statistics (2018–2023). 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 CLNA is generally robust when maintained correctly, but early units (2015–2017) are prone to HPFP issues if non-compliant fuel or oil is used. Later revisions improved durability. Adherence to VW 507 00 oil, EN 590 diesel, and timely AdBlue refills is essential for long-term reliability beyond 200,000 km.
Top issues include high-pressure fuel pump failure, AdBlue/SCR system faults, DPF clogging from short trips, and timing belt tensioner wear. These are documented in Volkswagen service bulletins and correlate with DVSA MOT failure trends for Euro 6 diesels.
The CLNA powered the Golf VII, Passat B8, and Tiguan II from 2015–2020 as the 2.0 TDI 150. It was also used in Škoda Superb III, SEAT Ateca, and other VW Group models with identical engine codes and Euro 6 compliance.
Yes. ECU remaps typically yield +20–30 kW (27–40 PS) and +60–80 Nm safely on stock hardware. The CP4.2 pump and turbo can support stage 1 tuning, but higher stages require upgraded fueling and intercooler. Always use VW 507 00 oil post-tune to manage increased stress.
Excellent. In a Golf 2.0 TDI 150, expect ~4.8 L/100km (city) and ~3.9 L/100km (highway), or ~58 mpg UK combined. Real-world mixed driving typically returns 50–60 mpg UK, depending on AdBlue usage and regeneration cycles.
Yes. The CLNA is an interference engine. If the timing belt fails or jumps, piston-to-valve contact can cause catastrophic damage. This underscores the importance of replacing the belt and tensioner at the prescribed 120,000 km or 5-year interval.
Volkswagen mandates VW 507 00 (5W-30) low-ash synthetic oil. This specification is critical for protecting the HPFP, turbo, and DPF. Never substitute with 504 00, 502 00, or generic ACEA C3 oils, as they lack required additives and can accelerate wear.
