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 Q5 2.0 TDI / 40 TDI Engine History & Specs at a Glance

When the Q5 launched, the 2.0 TDI quickly became the backbone of the range, evolving from the EA189 architecture in the 8R generation to the highly refined EA288 and the modern "40 TDI" power badge in the FY generation.

2008
CAHA, 2.0L TDI (177hp), launched in the 8R generation as the entry-level diesel workhorse.
2012
CGLB, 2.0L TDI (190hp), introduced during the 8R facelift with improved efficiency and Euro 5 compliance.
2017
CNHA, 2.0L TDI (190hp), carried over to the all-new FY generation on the MLB Evo platform, later adopting the "40 TDI" badge.
2020
DEJA / DEJB, 2.0L TDI (204hp) with 12V mild-hybrid technology, launched in the FY facelift strictly under the 40 TDI badge for Euro 6d compliance.

Common Problems

Audi Q5 2.0 TDI / 40 TDI Engine Problems Repair Cost vs Replacement

The Audi Q5 2.0 TDI / 40 TDI is a highly capable premium SUV, but its complex diesel architecture introduces specific failure points across the 8R and FY generations. The EA189 (CAHA/CGLB) and EA288 (CNHA/DEJA) engine codes dominate replacement demand for this variant. Rebuilt engines through EnginesMarket include upgraded components addressing the original failure point, plus a minimum 12-month unlimited-mileage warranty.

Common failure points and repair options

Oil Pump Drive & Timing Chain Failure

Affected: Audi Q5 2.0 TDI / 40 TDI (CAHA, CGLB, 2008-2017)
Typical failure mileage: 70,000-120,000 miles

Root cause

The oil pump hex shaft can snap due to wear, or the timing chain tensioner fails, resulting in sudden oil starvation or valve-to-piston interference that destroys the engine internally.

Repair options

Repair tier	Dealer price	Specialist price
Preventative Oil Pump / Chain Kit	£1,800-£2,500	£900-£1,500
Full Replacement - rebuilt/reconditioned engine	£5,500-£8,500	£3,200-£5,000

Our recommendation

For the 8R 2.0 TDI, if the engine is still running but you suspect oil pump or chain wear, a specialist preventative kit replacement is vastly cheaper than waiting for it to seize. However, if the hex shaft has already snapped or the chain has jumped, a rebuilt engine with an uprated oil pump drive is your only reliable path forward. For the FY 40 TDI, address coolant leaks immediately; a £1,000 specialist water pump and EGR upgrade is a minor expense compared to a £4,500+ full engine replacement.

EGR Cooler & Water Pump Leaks

Affected: Audi Q5 2.0 TDI / 40 TDI (CNHA, DEJA, 2017-present)
Typical failure mileage: 60,000-110,000 miles

Root cause

The plastic water pump and thermostat housing assembly becomes brittle and cracks, causing rapid coolant loss. Simultaneously, the EGR cooler can fail internally, mixing coolant and exhaust gases and triggering limp mode.

Repair options

Repair tier	Dealer price	Specialist price
Water Pump & EGR Cooler Replacement	£1,400-£2,200	£700-£1,400
Full Replacement - rebuilt/reconditioned engine	£6,500-£9,500	£3,800-£6,000
