Price Factors
Ancillaries: Quotes including the high-performance alternator, starter motor, and OPF (Otto Particulate Filter) will sit at the higher end of the band.
Warranty: A 12-month unlimited mileage warranty typically adds £200-£300 to the supply cost compared to a standard 3-month warranty, reflecting the higher baseline value of the unit.
VAT: Consumer quotes are typically VAT-inclusive, but B2B quotes may vary.

How to Confirm You Have the DAZA
The Audi 2.5 TFSI family uses multiple engine codes that share the same physical block but differ in ECU mapping, turbocharger specification, and emissions equipment. Fitting the wrong revision will trigger ECU faults, limp mode, and potentially fail an MOT emissions test. 1. Audi Data Label: Located in the service book or on a sticker in the boot under the carpet (often near the spare wheel well). The code is printed in the bottom right corner of the data sticker.
2. V5C Logbook: Check the "Engine Number" section, though this often lists the serial number rather than the three/four-letter code. 3. Under the Bonnet Sticker: Some models have a dedicated engine code sticker on the slam panel or inner wing. Confusable Sibling Codes DEJA: 2.5 TFSI (Previous Generation). Produces 400PS. Physically similar but lacks the OPF and features different turbo plumbing and ECU calibration. Not a direct plug-and-play swap. CZGA: 2.5 TFSI (Older Generation). Produces 340PS. Significantly different turbocharger, intercooler setup, and wiring loom. DNWA: 2.0 TFSI (Used in RS Q3 / Octavia vRS). Produces 300PS. This is a four-cylinder engine with a completely different block, mounting orientation, and ECU architecture. If you are sourcing a replacement DAZA engine, ensure the supplier guarantees the exact code. A DEJA unit will physically bolt into the same chassis mounts, but the ECU, exhaust routing, and turbo plumbing will not match without significant modification.
Easily Confused
Predecessor: Audi 2.5 TFSI (DEJA / CZGA)**
The DAZA directly evolved from the DEJA (400PS) and CZGA (340PS) iterations of the 2.5 TFSI. While the core 2,480cc inline-five block remains, the DAZA "evo" revision features a revised turbocharger, updated engine management, and the addition of an Otto Particulate Filter (OPF). A DEJA or CZGA unit will physically bolt into an 8Y RS3 or FV TT RS, but the differing ECU calibration, exhaust routing, and turbo plumbing will trigger persistent fault codes and MOT failures.
Alternative / Next-Gen Code
Cross-Brand Context: Volkswagen Group EA855 evo Family**
The DAZA is the pinnacle of the EA855 evo family. Unlike the ubiquitous four-cylinder EA888 engines found in lower-tier VW Group performance models (e.g., Golf R, S3), the DAZA’s inline-five architecture is exclusive to Audi’s highest-performance compact platforms. There are no direct SEAT, Škoda, or Volkswagen-badged equivalents to this specific five-cylinder configuration.

Buying Guide
Audi DAZA Buying Guide
Choosing the right replacement route depends on your budget, risk tolerance, and ownership goals. Here's a breakdown of your options.
Used:
A used DAZA engine (£2,500-£4,500 ) is a viable option if the donor vehicle has low mileage, a full Audi service history, and no evidence of aggressive ECU remapping. However, without a warranty on the turbocharger and water pump, you inherit the same failure risks. Explore used Audi engines .
Reconditioned:
The reconditioned DAZA (£4,500-£7,500 ) is the most popular choice for RS3 and TT RS owners. A proper reconditioning process validates the turbocharger, replaces all plastic coolant components with updated revisions, and performs a full compression and leak-down test. This addresses the engine's primary weak points and offers the best balance of cost and reliability. Compare reconditioned Audi engines .
Rebuilt:
A rebuilt DAZA (£6,000-£9,500 ) involves stripping the block to bare metal, machining the cylinder head and block, and replacing all internal bearings, pistons, and seals. This is highly recommended if the original DAZA suffered catastrophic failure due to track abuse, oil starvation, or aggressive tuning. View rebuilt Audi engines .
Supply & Fit Line:
Need a complete solution- Compare supply-and-fit Audi engine services .
Vehicle Value Note:
The typical UK market value for a DAZA-equipped vehicle (such as the Audi RS3 8Y or TT RS FV) ranges from £45,000 to £65,000+ . The replacement-to-value flag for the Audi DAZA is Safe. A reconditioned Audi DAZA engine replacement cost is well within the vehicle's value, making it a financially sound repair for most owners. However, if the lowest viable replacement cost exceeds approximately 60% of your specific vehicle's current market value, evaluate scrap value before committing.

FAQ
Audi DAZA Engine Replacement FAQ
Question 1How much does a reconditioned Audi DAZA 2.5 TFSI evo engine cost-
A reconditioned Audi DAZA engine typically costs between £4,500 and £7,500 for supply-only . This premium price band reflects the low-volume, high-performance nature of the unit, and ensures that known weak points (such as the plastic coolant components and turbocharger seals) have been addressed with updated revisions and validated via compression testing.
Compare DAZA quotesQuestion 2What are the most common failures of the Audi DAZA engine-
The two most documented failure patterns for the DAZA are plastic water pump and thermostat housing leaks (typically appearing between 40k-70k miles) and carbon buildup on the direct-injection intake valves (50k-80k miles). While the 2.5 TFSI evo is fundamentally robust, ignored coolant loss can rapidly lead to aluminium cylinder head warping, necessitating a full Audi DAZA engine replacement.
Compare DAZA quotesQuestion 3Can I fit a DEJA or CZGA engine in place of my failed DAZA-
Physically, the blocks share the same mounting points. However, the DAZA features an OPF, a revised turbocharger, and distinct ECU mapping to meet Euro 6d emissions standards. Fitting an older DEJA or CZGA unit without swapping the corresponding ECU, wiring loom, and exhaust components will result in persistent check engine lights, limp mode, and an automatic MOT failure. Always source an exact-code DAZA replacement.
Compare DAZA quotesQuestion 4How long does it take to replace an Audi DAZA engine-
Due to the tight packaging of the RS3 and TT RS engine bays, independent UK specialists typically quote 10 to 14 hours of labour for an Audi DAZA engine removal and refit (R&R). This translates to a typical fitted labour premium of £650 to £910 , depending on regional rates and whether ancillary components (like the OPF or high-output alternator) are transferred or replaced.
Compare DAZA quotesQuestion 5Is it worth replacing the engine in an Audi RS3 or TT RS with a DAZA code-
Yes, in the vast majority of cases. The typical UK market value for a DAZA-equipped Audi RS3 (8Y) or TT RS (FV Facelift) ranges from £45,000 to £65,000+ . The replacement-to-value flag for the Audi DAZA is Safe. A reconditioned Audi DAZA engine replacement cost is well within the vehicle's retained value, making it a financially sound repair. However, if the lowest viable replacement cost exceeds approximately 60% of your specific vehicle's current market value, evaluate scrap or part-exchange value before committing.
