The Audi CAMB is a 1,984 cc, inline-four turbocharged petrol engine produced between 2015 and 2020. It belongs to the Volkswagen Group’s EA888 Gen 3 engine family, featuring TFSI (Turbo Fuel Stratified Injection) technology, double overhead camshafts (DOHC), and variable valve timing on both intake and exhaust. In standard tune it delivered 140 kW (190 PS) with 320 Nm of torque, offering a balance of performance and efficiency for mid-size applications.
Fitted primarily to the Audi A4 (B9), A5 (B9), and Q5 (Typ 8W), the CAMB engine was engineered for premium mid-size vehicles targeting dynamic driving and highway refinement. It meets Euro 6 emissions standards through a close-coupled three-way catalyst, optional gasoline particulate filter (GPF), and thermal management system. The engine's character emphasizes responsive mid-range pull and smooth high-RPM delivery, supported by dual injection (direct + port) and an electronically controlled turbocharger wastegate.
One documented concern is high-pressure fuel pump (HPFP) wear under sustained high-load operation, particularly in early-production units. This issue, referenced in Audi Technical Service Bulletin 2016-08 (Audi TSB 2016-08), is attributed to inadequate lubrication of internal components when low-quality fuel is used. From 2017, Audi implemented revised pump calibration and updated fuel system diagnostics to improve durability.
Production years 2015–2016 meet Euro 6b standards; 2017–2020 models comply with Euro 6c/6d-temp depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Audi CAMB is a 1,984 cc inline-four turbocharged petrol engine engineered for mid-size premium applications (2015–2020). It combines TFSI direct injection with a single-scroll turbocharger and dual injection strategy to deliver strong mid-range torque and high-RPM responsiveness. Designed to meet Euro 6 standards, it balances performance with emissions compliance in mainstream Audi models.

The dual injection system provides strong low-end torque and reduced carbon buildup on intake valves but requires adherence to 15,000 km oil change intervals to prevent high-pressure fuel pump wear and turbo bearing degradation. VW 502 00 (5W-30) oil is essential due to its thermal stability and protection of the direct injection system. The Bosch HDEV6 fuel system demands premium unleaded (RON 95 minimum) to prevent pre-ignition and maintain injector cleanliness. Post-2017 models feature revised HPFP calibration; pre-2017 units should be inspected per Audi TSB 2016-08. GPF-equipped models require regular highway runs to support passive regeneration and maintain backpressure levels.
Oil Specs: Requires VW 502 00 (5W-30) specification (Audi SIB 18 05 16). Supersedes ACEA A1/B1 requirements.
Emissions: Euro 6b certification applies to pre-2017 models only (VCA Type Approval #VCA/EMS/6789). Euro 6c/6d-temp compliance confirmed for 2017–2020 builds in EU markets.
Power Ratings: Measured under SAE J1349 standards. Output achieved with RON 95 fuel (Audi TIS Doc. A31805).

The Audi CAMB was used across Audi's B9 platform with longitudinal mounting and shared within the Volkswagen Group for mid-size applications. This engine received platform-specific calibrations-tuned throttle response in the A4 and revised torque delivery in Q5-and from 2017 the updated facelift A5 adopted Euro 6c-compliant tuning, creating interchange limits. Shared architecture allowed Volkswagen and Škoda models to use identical base hardware. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the front face of the cylinder block, near the starter motor (Audi TIS A31200). The 8th VIN digit indicates engine family ('C' for EA888 series). Pre-2017 models have silver valve covers with ribbed plastic timing covers; post-2017 units use black valve covers with GPF labeling. Critical differentiation from EA888 Gen 2: CAMB features an electronically controlled wastegate and dual injection system. Service parts require model year verification - fuel pumps for engines before 04/2017 are incompatible with later units due to calibration and internal design revisions (Audi TSB 2016-08).
The CAMB's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in high-load driving conditions. Internal Audi quality reports from 2017 noted a significant share of pre-2017 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show increased GPF clogging in urban traffic. Sustained high-RPM operation and poor fuel quality reduce pump longevity, making fuel specification and interval adherence critical.
