Audi Q5 SQ5 3.0 TDI / TFSI Engine Replacement Compare Prices & Get Quotes

A reconditioned Audi Q5 SQ5 3.0 TDI / TFSI V6 engine costs £4,500-£7,500 supply-only, or £6,000-£9,500 fully fitted depending on the generation (8R TDI vs FY TFSI) and supplier location. Used engines start around £2,500 but carry higher risk for complex V6 components.

• 8R SQ5 (CAPA/CJCD, 313hp): £4,500-£7,500 reconditioned
• FY SQ5 (CGQC, 354hp): £4,500-£7,500 reconditioned

Common symptoms include a distinct rattling or whining noise from the front of the engine, reduced boost pressure, and intermittent check engine lights. You may also notice coolant loss if the crossover pipes have become brittle.

• Rattling noise at idle indicates supercharger coupler wear
• Coolant puddles under the front of the vehicle suggest pipe failure
• ECU fault codes for boost pressure deviation or coolant temperature

For FY generation cars (2017-present) valued £22,000-£45,000, a rebuilt engine at £6,000-£9,500 typically represents excellent value if you plan to keep the car 2+ years. For older 8R models under £8,000, evaluate the scrap value first.

• 8R SQ5 (2009-2017): Worth £8k-£22k; reconditioned is viable for well-maintained examples
• FY SQ5 (2017-present): Worth £22k-£45k; rebuilt engine is a small percentage of total value

A complete V6 engine swap typically takes 2 to 3 days for a supply-and-fit service. The FY generation requires additional time for supercharger calibration, ECU component protection removal, and online immobiliser coding via ODIS (Audi's diagnostic system).

• Engine removal and installation: 12-16 hours
• ECU coding and quattro calibration: 3-5 hours
• Road testing and system verification: 2-3 hours

The 8R generation (2009-2017) used a 3.0 TDI V6 (CAPA/CJCD) producing 313hp, favoured for torque and towing. The FY generation (2017-present) switched to a 3.0 TFSI V6 (CGQC) producing 354hp, featuring a roots-type supercharger for instant petrol performance and smoother refinement.

• 3.0 TDI (CAPA/CJCD): 2009-2017, 313hp, turbo diesel
• 3.0 TFSI (CGQC): 2017-present, 354hp, supercharged petrol
