How it works

3 Simple Steps to Finding the Right Replacement Engine

Clear information first, then the right engine and specialist for your exact vehicle.

Variant History

Audi A5 2.0 TDI / 35/40 TDI Engine History & Specs at a Glance

When the 2.0 TDI was introduced to the Audi A5 range, it quickly became the dominant powertrain, offering a balance of torque, efficiency, and refinement. Over its production run, it evolved from the EA189 unit-injector platform to the highly refined EA288 common-rail diesel, adopting the modern 35 TDI and 40 TDI badging conventions in later years.

2007
CAGB engine code introduced (143hp), establishing the 2.0 TDI baseline for the B8 generation.
2009
CGLB engine code introduced (170hp), featuring updated injection mapping for higher-spec B8 variants.
2016
CNHA engine code introduced (190hp) for the B9 generation, badged as 40 TDI, featuring improved common-rail injection and emissions controls.
2019
DEUA and DETA engine codes introduced (150hp) for the B9 facelift, badged as 35 TDI, integrating refined AdBlue systems and updated EGR cooling for stricter Euro 6d compliance.

Common failure points and repair options

EGR Cooler & Valve Clogging

Affected: Audi A5 2.0 TDI / 35/40 TDI (CAGB, CGLB, CNHA, 2007-2020)
Typical failure mileage: 80,000-150,000 miles

Root cause

Carbon buildup from exhaust gas recirculation restricts flow and can cause the EGR cooler to leak coolant into the intake, leading to overheating or hydrolock if ignored.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	£600-£1,200	£400-£800
Full Replacement - rebuilt/reconditioned engine	£4,500-£7,000	£3,200-£5,000

Our recommendation

For older B8 models approaching the lower end of the value spectrum, a verified low-mileage used engine or targeted EGR/DPF repair is often the most economically viable route. For B9 35/40 TDI models, a reconditioned engine is a strong investment, provided the specialist verifies the AdBlue and DPF systems are fully functional to prevent repeat issues.

DPF Blockage & AdBlue System Faults

Affected: Audi A5 2.0 TDI / 35/40 TDI (CNHA, DEUA, DETA, 2016-present)
Typical failure mileage: 80,000-150,000 miles

Root cause

Frequent short urban journeys prevent active DPF regeneration, while AdBlue heater or NOx sensor failures trigger emissions-related limp mode, restricting engine performance.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	£800-£1,500	£400-£1,200
Full Replacement - rebuilt/reconditioned engine	£5,500-£8,000	£3,800-£6,000
