Audi A4 EA888/EA189/EA288 Engine SolutionsUK Specialists

Audi A4 engine replacement costs typically range from £1,100 to £4,500 supply-only, depending on engine code, variant and rebuild type. The ubiquitous 2.0 TDI diesel (CAGA, CFFB) sits at the lower end, while 2.0 TFSI petrol (CAEB, CYRB) and 3.0 TDI V6 units command higher prices due to complexity and specialist demand.

• Rebuilt 2.0 TDI engines typically cost £1,200-£3,400 supply-only across UK specialists
• EA888 petrol units (CAEB, CYRB) range £1,400-£3,800 due to timing chain upgrades
• Supply and fit labour adds £400-£800 depending on location and variant complexity
• Prices include minimum 12-month unlimited mileage warranty from vetted UK specialists

Compatible Audi A4 engine codes depend on your chassis generation (B8: 2008-2015, B9: 2015-present) and fuel type. Key diesel codes include CAGA, CFFB, CNHA, DEUA; petrol codes include CAEB, CYRB, DKZA, CZDA. Always verify via your VIN or registration to guarantee ECU and emissions compatibility before ordering.

• B8 generation (2008-2015) commonly uses CAGA, CFFB diesel and CAEB petrol codes
• B9 generation (2015-present) features CNHA, DEUA diesel and CYRB, DKZA petrol units
• Engine codes must match chassis calibration for ECU, DPF and AdBlue system compatibility
• Enter your registration above to instantly verify the exact engine code for your Audi A4

Audi A4 engines most frequently suffer timing chain tensioner wear on pre-2012 EA888 petrol units, excessive oil consumption on EA888 Gen 3 engines, and EGR cooler leaks or DPF faults on 2.0 TDI diesels. These issues are well-documented across UK owner forums and drive the majority of replacement enquiries for B8 and B9 generation models.

• Pre-2012 EA888 TFSI engines (CAEB) prone to timing chain tensioner failure at 60k-100k miles
• EA888 Gen 3 petrol units (CYRB, DKZA) exhibit oil consumption from narrow piston ring drains
• 2.0 TDI diesels (CAGA, CFFB, CNHA) commonly experience EGR cooler fracture and DPF blockage
• Rebuilt engines from our network include upgraded components addressing these known failure points

For reliability, late B9 2.0 TDI units with CNHA or DEUA codes (2019-2023) offer the strongest track record, benefiting from refined emissions hardware and improved calibration. Among petrol options, post-2012 EA888 Gen 3 engines (CYRB, DKZA) resolved early timing chain concerns, though regular oil changes remain critical for longevity.

• CNHA/DEUA 2.0 TDI engines (B9, 2019-2023) show lowest failure rates in UK owner surveys
• EA888 Gen 3 petrol codes (CYRB, DKZA) fixed pre-2012 timing chain tensioner design flaws
• Avoid pre-2012 CAEB TFSI units unless timing chain kit has been professionally upgraded
• Full service history and documented oil changes significantly extend lifespan across all Audi A4 engines

For most Audi A4 owners, replacing with a rebuilt engine offers better long-term value than repairing individual components, especially when known failure points like timing chains or EGR coolers are involved. A quality rebuilt unit includes upgraded internals, bench testing, and a 12-month warranty - often costing less than cumulative repair bills on high-mileage examples.

• Rebuilt Audi A4 engines include upgraded components addressing original design weaknesses
• Supply-only rebuilt units typically cost £1,100-£4,500 versus £2,000+ for piecemeal major repairs
• All engines from our network carry minimum 12-month unlimited mileage warranty for peace of mind
• Replacement preserves vehicle value and avoids repeated downtime from sequential component failures

Every Audi A4 replacement engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty from vetted UK specialists. Coverage typically includes parts and labour for manufacturing defects, with options to extend. Always confirm exact terms with your chosen supplier, as warranty scope can vary between reconditioned, rebuilt and remanufactured units.

• Minimum 12-month unlimited mileage warranty standard across all EngineMarket network suppliers
• Warranty covers parts and labour for manufacturing defects on rebuilt and remanufactured units
• Reconditioned and used engines may carry shorter or conditional warranty terms - verify before ordering
• Keep all service records and installation documentation to maintain warranty validity on your Audi A4

Audi A4 engine replacement typically takes 2-5 working days from order to collection, depending on engine code availability and whether you choose supply-only or supply and fit. Common 2.0 TDI codes (CAGA, CFFB) often ship next-day, while specialist units like 3.0 TDI V6 or PHEV variants may require 3-5 days for calibration matching and bench testing.

• Supply-only rebuilt engines for common Audi A4 codes often dispatch within 24-48 hours
• Supply and fit service adds 1-2 days for garage scheduling, collection and professional installation
• Complex variants (quattro, PHEV, Allroad) may require additional calibration time for ECU adaptation
• Nationwide delivery available; many specialists offer collection and return service for your Audi A4

Most Audi A4 petrol engines from 2010 onwards are E10 compatible, including EA888 Gen 3 TFSI units (CYRB, DKZA). Earlier CAEB engines (pre-2012) and all 2.0 TDI diesel variants (CAGA, CFFB, CNHA) remain unaffected as E10 applies to petrol only. Verify compatibility via your VIN on the government E10 checker before switching fuels.

• EA888 Gen 3 petrol engines (CYRB, DKZA, 2012+) are officially E10 compatible per Audi UK
• Pre-2012 CAEB TFSI units may experience increased corrosion risk with E10 ethanol blends
• All Audi A4 diesel engines (TDI) are unaffected as E10 applies to petrol pumps only
• Using incompatible fuel can void warranty and cause fuel system damage on non-approved Audi A4 engines

A professionally rebuilt Audi A4 engine with full documentation and warranty typically preserves or even enhances resale value compared to a vehicle with known engine faults. Buyers prioritise verified service history, OEM-spec components, and warranty coverage over whether the engine is original, especially on high-mileage B8 and B9 examples where replacement is common.

• Documented rebuilt engines with warranty often increase buyer confidence versus unknown fault history
• OEM-spec or upgraded components maintain Audi A4 performance and MOT compliance standards
• Keep all invoices, calibration records and warranty paperwork to demonstrate quality of replacement work
• Numbers-matching original engines command premium only on low-mileage collector-spec Audi A4 variants

For most Audi A4 owners, independent VAG specialists offer comparable quality to main dealers at 30-50% lower cost, with faster turnaround and more flexible warranty terms. Specialists focusing on Audi/VW platforms understand B8/B9 calibration nuances, ECU adaptation, and emissions system requirements without the dealer premium on parts and labour rates.

• Independent VAG specialists typically charge £400-£800 less for supply and fit versus main dealer rates
• Specialist rebuilders often include upgraded components addressing known Audi A4 failure points as standard
• Main dealers may require full engine replacement rather than targeted rebuilds, increasing overall cost
• Verify specialist credentials, warranty terms and calibration capability before committing to any Audi A4 engine work
