Vauxhall Zafira 2.0 CDTI Engine ReplacementCompare Prices & Get Quotes

A Vauxhall Zafira 2.0 CDTI engine replacement costs between £2,800 and £5,500 supply-only for a rebuilt unit, with fitting adding £600-£1,200 depending on your location and whether you choose a Vauxhall specialist or main dealer. Used A20DT or A20DTH engines can be found from £1,000-£2,200, but come with no warranty and no upgraded components.

• Rebuilt A20DT: £2,800-£3,800 supply only
• Rebuilt A20DTH: £3,200-£4,500 supply only
• Rebuilt B20DTH: £4,000-£5,500 supply only
• Specialist fitting: £600-£1,200 additional (8-12 labour hours)

For all Zafira 2.0 CDTI variants: engine management light illumination, loss of power, limp mode activation, rattling on cold start (timing chain wear), excessive smoke, and increased fuel consumption. For B20DTH models specifically: AdBlue warning lights and NOx sensor failures.

• Timing chain rattle: cold start noise from 80,000-120,000 miles
• EGR/DPF issues: warning lights, reduced power from 40,000-80,000 miles
• Injector/turbo failure: misfire, overboost, limp mode from 80,000-150,000 miles

Yes, if your Zafira 2.0 CDTI is otherwise sound and has no major body or chassis issues. A 2014-2017 Zafira 2.0 CDTI values between £5,000 and £12,000, making a £2,800-£5,500 rebuilt engine replacement - around 25-45% of the car's value - a decision that depends on ownership horizon. For older examples under £4,000, evaluate scrap value before committing. For higher-value B20DTH examples over £8,000, replacement is usually justified.

• Replacement cost typically 25-50% of vehicle value for older examples
• Rebuilt engines come with 12-month unlimited-mileage warranty
• Keep the car for 2+ years: replacement makes strong financial sense for mid-to-high value examples

A full Vauxhall Zafira 2.0 CDTI engine replacement typically takes 2-5 working days from delivery of the replacement engine. Specialist fitters often complete the work in 2-3 days, while main dealers may take 4-5 days due to scheduling. Mobile fitters offering supply & fit at your location may operate on different turnaround times.

• Specialist workshop: 2-3 days typical
• Main dealer: 4-5 days typical
• Mobile fitting: variable - confirm before booking

The Zafira 2.0 CDTI range includes several engine codes with different power outputs. A20DT (110hp) and A20DTL (110hp) are entry-level Euro 5 units. A20DTH (160-165hp) is the higher-output Euro 5 variant. B20DTH (170hp, 400Nm) and D20DTH (170hp) are Euro 6 units with BlueInjection AdBlue technology from 2014 onwards.

• A20DT/A20DTL: 110hp, lowest cost, Euro 5
• A20DTH: 160-165hp, most common Euro 5
• B20DTH/D20DTH: 170hp, 400Nm, Euro 6, most powerful

The Zafira 2.0 CDTI is a generally robust and torquey diesel, but emissions system issues (EGR, DPF, AdBlue) are common on all modern diesels. The B20DTH is the most powerful and most complex, with additional BlueInjection SCR components that can fail. Timing chain wear is a known issue on higher-mileage examples. Regular servicing with the correct low-ash engine oil and motorway driving for DPF regeneration are essential for longevity.

• A20DTH: robust but timing chain wear from 80,000 miles
• B20DTH: most powerful, but AdBlue system adds complexity
• All: EGR/DPF issues in urban-only driving
