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 Q7 30 TFSI / 55 TFSI Engine History & Specs at a Glance

The 55 TFSI badging on the Audi Q7 denotes the potent 3.0-litre V6 turbocharged petrol engine, introduced to replace the previous supercharged variants and offer a balance of performance and efficiency, often paired with mild-hybrid technology in later 4M models. (Note: "30 TFSI" is not a standard UK Audi Q7 engine designation; this page comprehensively covers the verified 55 TFSI 3.0L V6 powertrains that define this performance tier).

2015
CGWA and CZDA engine codes introduced (3.0L V6 TFSI, 252hp) for the 4M generation, replacing the previous supercharged units with a more efficient twin-scroll turbo setup.
2018
DZKA engine code introduced (3.0L V6 TFSI, 340hp) for the 55 TFSI badge, integrating a 48V mild-hybrid system (MHEV) for improved efficiency, smoother stop-start operation, and enhanced torque delivery.

Every engine fitted to the Audi Q7 30 TFSI / 55 TFSI is covered below, with UK rebuilt pricing and known failure points.

Common failure points and repair options

High-Pressure Fuel Pump & Water Pump Failure

Affected: Audi Q7 30 TFSI / 55 TFSI (CGWA, CZDA, DZKA, 2015-present)
Typical failure mileage: 60,000-100,000 miles

Root cause

Plastic impellers within the water pump degrade under sustained heat cycles, and HPFP internal seals wear, leading to coolant loss or lean running conditions that can cause severe internal damage if ignored.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	£800-£1,500	£500-£900
Full Replacement - rebuilt/reconditioned engine	£7,000-£10,000	£5,000-£8,500

Our recommendation

For the 55 TFSI, preventative replacement of the water pump and thermostat housing is highly advised before catastrophic failure occurs. If you are dealing with an earlier CGWA or CZDA unit that has suffered HPFP or timing chain failure, a rebuilt engine with the revised components is the most reliable long-term solution.

Carbon Buildup & Timing Chain Tensioner Wear

Affected: Audi Q7 30 TFSI / 55 TFSI (CGWA, CZDA, 2015-2018)
Typical failure mileage: 70,000-120,000 miles

Root cause

Direct injection lacks fuel washing over intake valves, causing restrictive carbon deposits. Early timing chain tensioners can also stretch, risking catastrophic valve-to-piston contact.

Repair options

Repair tier	Dealer price	Specialist price
Minor/Preventative	£600-£1,200	£400-£700
Full Replacement - rebuilt/reconditioned engine	£7,000-£10,000	£5,000-£8,500
