The Volkswagen CLCA is a 1,968 cc, inline‑four turbocharged diesel engine produced between 2010 and 2015. It features common — rail direct injection, dual overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). In standard form it delivered 103 kW (140 PS) and 320 Nm of torque, offering strong low — end responsiveness with fuel — efficient cruising.

All production years 2010–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6743).
The Volkswagen CLCA is a 1,968 cc inline‑four turbocharged diesel engineered for compact and mid‑size models (2010–2015). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong low-end torque and efficient highway cruising. Designed to meet Euro 5 emissions standards, it balances everyday usability with diesel efficiency.

The Volkswagen CLCA was used across Volkswagen's A5/B6/5N platforms with transverse mounting and shared with Škoda and SEAT under the VAG group. This engine received platform-specific adaptations—revised EGR routing in the Passat B7 and enhanced cooling in the Tiguan—and from 2012 the updated Golf Mk6 facelift retained the CLCA while later models transitioned to EA288. All adaptations are documented in OEM technical bulletins.
The CLCA's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in high-mileage or cold-climate use. Volkswagen internal field data from 2013 indicated a notable rate of timing-related repairs before 120,000 km, while UK DVSA records show secondary issues with DPF regeneration faults in short-trip urban use. Extended oil intervals and poor-quality diesel accelerate wear, making oil/fuel quality and service adherence critical.
Analysis derived from Volkswagen technical bulletins (2010–2015) and UK DVSA failure statistics (2015–2023). 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 CLCA offers strong efficiency and refinement, but early units (2010–mid-2012) are prone to timing chain tensioner wear. Later revisions improved durability. With strict maintenance—VW 507 00 oil, quality diesel, and regular highway driving for DPF regeneration—well-cared-for examples can exceed 200,000 km reliably.
Top issues include timing chain tensioner wear, DPF regeneration failure in urban use, EGR valve coking, and high-pressure fuel pump wear. These are documented in VW service bulletins like STB 2012‑04 and widely observed in EA189-family diesels.
The CLCA powered the Golf Mk6, Passat B6/B7, Tiguan, plus Škoda Superb II and SEAT Exeo from 2010–2015. All meet Euro 5 emissions and use the EA189 engine family architecture.
Yes. The CLCA responds well to ECU remapping, typically gaining +20–30 kW on stage 1 with stock hardware. Supporting upgrades (intercooler, DPF delete—where legal) allow 180+ PS safely. However, timing chain and turbo reliability must be confirmed before tuning to avoid accelerated wear.
In a Golf 2.0 TDI, expect ~5.4 L/100km (city) and ~4.2 L/100km (highway), or ~52 mpg UK combined. Passat variants average 5.8–6.2 L/100km (~46 mpg UK). Real-world economy depends heavily on driving style, DPF health, and adherence to service intervals.
Yes. The CLCA is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic internal damage. Regular oil changes and chain system inspection are essential to prevent this.
Volkswagen specifies 5W‑30 synthetic oil meeting VW 507 00 standards. Always use VW-approved oil and change every 15,000 km or annually to protect the turbo, timing chain, and emissions systems.
