AUDI DFTA engine (2019–2023) – Specs, Problems & Compatibility Database

The Audi DFTA is a 1,968 cc, inline-four turbo-diesel engine produced between 2019 and 2023. It belongs to the Volkswagen Group’s EA288 evo engine family, featuring common rail direct injection, a variable geometry turbocharger (VGT), and a cast-iron block with an aluminium head. In standard tune it delivers 140 kW (190 PS) with peak torque of 400 Nm available from 1,750 rpm, providing strong low-end pull ideal for daily driving and towing applications.

Fitted to models including the Audi A6 (C8), A7 (4K), and Q7 (4M), the DFTA was engineered for longitudinal front- and quattro all-wheel-drive platforms requiring high torque and premium refinement. It meets Euro 6d emissions standards through a close-coupled diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, ensuring compliance without sacrificing performance in flagship vehicles.

One documented service update involves revised high-pressure fuel pump calibration to reduce wear under sustained load, addressed in Audi Technical Service Bulletin 2020-23-02. Early production units exhibited elevated injector tip coking under frequent short-trip conditions. From 2020, Audi implemented updated ECU mapping and revised fuel nozzle geometry, improving soot management and long-term injector durability.

Practical Implications

The VGT turbo provides strong low-RPM torque ideal for urban and motorway driving but requires regular longer runs to maintain DPF regeneration cycles and prevent clogging. Audi Longlife Diesel VW 507.00 (0W-30) oil is essential due to its low-SAPS formulation, protecting the SCR system and turbo bearings. Extended idling and short trips increase soot loading; drivers should complete 20-minute highway drives monthly. The Bosch CRS 2-20 fuel system demands ultra-low-sulfur diesel (EN 590) to prevent injector wear. From 2020, revised ECU maps per Audi TSB 2020-23-02 improve injector longevity and emissions performance.

DFTA Compatible Models

The Audi DFTA was used across Audi's C8/4K platforms with longitudinal mounting and shared within the Volkswagen Group for premium applications. This engine received platform-specific adaptations-tuned throttle response in the A7 and revised cooling circuits in the Q7-and from 2021 the facelifted C8.5 revision introduced updated ECU calibration and SCR monitoring, creating interchange limits. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped vertically on the right-side cylinder block near the oil filter housing (Audi TIS A28815). The 8th VIN digit indicates engine family ('D' for EA288 diesel). Pre-2020 models have silver valve covers with exposed camshafts; post-2020 units use black covers with integrated breather. Critical differentiation from EA288 2.0 TDI 177 PS: DFTA uses a single-stage VGT turbo, while lower-output variants use a smaller turbo unit. Service parts require production date verification - fuel injectors for pre-2020 models are not compatible with post-2020 revisions due to nozzle redesign (Audi TSB 2020-23-02).

Identification Details

Compatibility Notes

Evidence:

Audi TSB 2020-23-02

Fuel Components:

Fuel injectors and high-pressure pump assemblies for pre-2020 DFTA engines are not compatible with post-2020 Euro 6d revisions due to updated nozzle geometry and calibration per Audi TSB 2020-23-02.
Injector Update

Issue:

Early DFTA units experienced injector tip coking under frequent short-trip operation, leading to reduced injection efficiency and increased particulate emissions.

Evidence:

Audi TSB 2020-23-02

Recommendation:

Install updated ECU mapping and nozzle geometry per Audi TSB 2020-23-02 during service intervals.

Common Reliability Issues - AUDI DFTA

The DFTA's primary reliability risk is DPF clogging in urban-driven vehicles, with elevated incidence in stop-start city use. Internal Audi quality reports from 2021 indicated a notable share of pre-2020 engines requiring DPF cleaning before 100,000 km, while UK DVSA records show increased emissions-related failures in SCR-equipped post-2020 models. Frequent short trips and delayed oil changes increase soot and thermal stress, making driving pattern and service interval adherence critical.

Diesel particulate filter (DPF) clogging
Symptoms: Reduced power, limp mode, frequent regeneration cycles, increased fuel consumption.
Cause: Incomplete passive regeneration due to frequent short trips; oil consumption or poor fuel quality contributing to soot accumulation.
Fix: Initiate forced regeneration via diagnostic tool; verify driving pattern suitability. Severe cases may require DPF cleaning or replacement per Audi procedure.
High-pressure fuel injector coking
Symptoms: Rough idle, misfires, reduced power, black smoke under load.
Cause: Carbon buildup on injector tips due to prolonged low-load operation and inadequate combustion temperatures.
Fix: Clean or replace injectors; update ECU mapping per Audi TSB 2020-23-02 to improve injection strategy and reduce coking.
EGR/DOC system fouling
Symptoms: Rough idle, hesitation, excessive smoke, DTCs related to EGR flow or catalyst efficiency.
Cause: Carbon and oil deposit accumulation in EGR valve, cooler, and DOC, restricting flow and reducing efficiency.
Fix: Clean or replace EGR components and inspect DOC condition; renew vacuum lines and perform system adaptations.
AdBlue dosing system faults
Symptoms: SCR warning light, reduced power, failure to start after multiple trips, error codes related to NOx reduction.
Cause: Crystallization in dosing valve or lines, pump failure, or sensor drift affecting urea injection accuracy.
Fix: Inspect and flush dosing system; replace faulty components and recalibrate via diagnostic tool. Use only ISO 22241-compliant AdBlue.
