The Volkswagen DPCA is a 1,598 cc, inline‑four turbo‑diesel engine produced between 2015 and 2020. It features common rail direct injection, a single variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 85 kW (115 PS) and 250 Nm of torque, engineered for responsive urban driving and efficient highway cruising.
Fitted to models such as the Mk7 Golf, Mk2 Tiguan, and Passat B8—including the 1.6 TDI 115 variants—the DPCA wa…
All DPCA production years (2015–2020) meet Euro 6b/6d-TEMP standards depending on model year and market .
The Volkswagen DPCA is a 1,598 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 and AdBlue-based SCR to deliver strong low‑rpm torque and low NOx emissions. Designed to meet Euro 6 standards, it balances everyday drivability with regulatory compliance.

The Volkswagen DPCA was used across Volkswagen's Mk7/B8 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—reinforced mounts in the Tiguan and revised cooling in the Passat—and from 2018 the updated DPCB variant introduced minor ECU and camshaft changes, creating interchange limits. Group synergy allowed use in Škoda and Audi derivatives with identical core architecture. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DPCA is generally robust if maintained properly, but early units (2015–2017) are prone to camshaft HPFP lobe wear. Post-2018 revisions improved durability. Using VW 507 00 oil and avoiding constant short trips greatly enhances longevity. AdBlue system reliability depends on fluid quality and driving patterns.
Top issues include camshaft wear driving the high-pressure fuel pump, AdBlue system faults (injector clogging, NOx sensor errors), DPF regeneration failures from urban use, and minor oil leaks. These are documented in Volkswagen SIB 2017‑09 and TIS service updates.
The DPCA powered the Golf VII, Passat B8, Tiguan II, Škoda Octavia III, and Audi A3 8V—all with 1.6 TDI 115 PS output from 2015–2020. It’s part of the EA288 evo diesel family and meets Euro 6 emissions via SCR and DPF.
Aftermarket ECU tuning is common on the DPCA 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.
Excellent. In a Golf 1.6 TDI 115, expect ~4.5 L/100km (city) and ~3.3 L/100km (highway), or ~63 mpg UK combined. Real-world mixed driving typically returns 55–65 mpg (UK), depending on AdBlue usage and DPF regeneration cycles.
Yes. The DPCA is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is generally durable with proper oil changes.
Volkswagen mandates 5W-30 synthetic oil meeting VW 507 00 specification. This low-SAPS oil protects the DPF and ensures proper lubrication of the cam-driven HPFP. Never use 504 00 or non-approved oils—doing so risks cam wear and DPF clogging.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
