The Volkswagen CHPB is a 1,984 cc, inline‑four turbo‑charged petrol engine produced between 2012 and 2019. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 162 kW (220 PS) and 350 Nm of torque. The integrated exhaust manifold enables faster warm‑up and reduced emissions.
Fitted to models including the Mk7 Golf R, Mk3 Scirocco R, and Audi S3 (8V), the CHPB was engineered for high‑performance driving with everyday usability. Emissions compliance was achieved through a combination of three‑way catalytic converter, secondary air injection, and precise lambda control, meeting Euro 5 and Euro 6 standards depending on model year.
One documented concern is high‑pressure fuel pump (HPFP) wear, leading to hard starts or limp mode. This issue is referenced in Volkswagen Service Technical Bulletin 2015‑07‑01, attributed to prolonged exposure to marginal fuel quality and thermal stress. From 2016, revised HPFP internals and updated cam follower materials were introduced to mitigate premature wear.
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CHPB is a 1,984 cc inline‑four turbo‑charged petrol engine engineered for performance hatchbacks and coupes (2012–2019). It combines direct fuel injection (TSI) with a twin‑scroll turbocharger to deliver responsive power and strong mid‑range torque. Designed to meet Euro 5 and Euro 6 emissions standards, it balances track capability with daily drivability.

The twin‑scroll turbo provides linear power delivery and minimal lag, ideal for spirited driving, but demands high‑quality fuel (RON 98) to prevent knock and HPFP wear. Oil must meet VW 502 00/504 00 (5W‑40) and be changed every 15,000 km or annually to protect the timing chain and VANOS system. The high‑pressure fuel pump relies on lubrication from fuel, so prolonged use of low‑lubricity petrol accelerates cam follower wear. Post‑2016 engines include an upgraded HPFP follower per VW STB 2015‑07‑01. Carbon buildup on intake valves is minimal due to direct injection, but occasional induction service is advised for high‑mileage units.
Oil Specs: Requires VW 502 00 / 504 00 (5W‑40) specification (Volkswagen Owner’s Manual). Not interchangeable with Longlife‑04 diesel oils.
Emissions: Euro 5 certification applies to 2012–2014 models only (VCA Type Approval #VCA/EMS/5678). All 2015–2019 units meet Euro 6.
Power Ratings: Measured under ISO 1585 standards. Peak output assumes RON 98 fuel and intact boost control (Volkswagen TIS Doc. 06K‑2105).

The Volkswagen CHPB was used across Volkswagen's Mk7 and Mk3 platforms with longitudinal mounting and shared with Audi under the VW Group modular strategy. This engine received platform-specific adaptations—reinforced mounts in the Golf R and modified cooling in the Scirocco R—and from 2016 the Golf R facelift adopted updated HPFP components, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filler neck (Volkswagen TIS 06K‑1001). The 4th–6th characters of the engine code on the VIN plate (e.g., “CHP”) confirm family; full code “CHPB” appears in service labels under the boot lid or on the maintenance booklet. Visual cue: CHPB uses a black plastic intake manifold with “2.0 TSI” embossed and an IHI IS20 turbo with twin‑scroll housing. Differentiate from CAHA/CJSA: CHPB has a revised camshaft lobe profile for HPFP drive and updated PCV system. HPFP followers for pre‑2016 engines are not interchangeable with post‑2016 units due to material change (VW STB 2015‑07‑01).
The CHPB's primary reliability risk is high-pressure fuel pump (HPFP) and cam follower wear, with elevated incidence in vehicles using low-lubricity fuel or extended service intervals. Volkswagen internal field data (2016) indicated a measurable uptick in HPFP-related DTCs before 80,000 km in non‑compliant fuel regions, while UK DVSA MOT data shows low failure rates for emissions systems due to robust catalyst design. Fuel quality and oil specification adherence make long-term durability highly dependent on owner maintenance practices.
Analysis derived from Volkswagen technical bulletins (2014–2018) and UK DVSA failure statistics (2016–2023). Repair procedures should follow manufacturer guidelines.
