Vauxhall Astra 17 CDTI Engine Replacement Compare Prices & Get Quotes

A Vauxhall Astra 17 CDTI engine replacement typically costs £1,800-£3,000 supply-only for a rebuilt A17DTE unit, with used engines from £800 and reconditioned from £1,500. Total fitted cost adds 8-12 hours of labour at specialist rates (£65-£85/hr) or dealer rates (£120-£180/hr).

• Rebuilt supply-only: £1,800-£3,000 [ESTIMATED]
• Supply & fit specialist total: £2,300-£4,000
• Main dealer supply & fit: £3,000-£5,500

The most common sign of timing chain stretch in the Vauxhall Astra 17 CDTI is a metallic rattle on cold start, lasting 1-3 seconds. As wear progresses, you may hear a continuous rattle, experience poor acceleration, or see the engine management light illuminate with camshaft correlation fault codes.

• Cold-start rattle is the earliest warning - don't ignore it
• If the chain jumps, the engine will not start or may run very roughly
• Catastrophic failure can bend valves, requiring a full engine replacement

This depends on your Astra 17 CDTI's overall condition and market value. For a well-maintained Mk6 facelift SRi or Elite (worth £4,000-£8,000), a rebuilt engine at £1,800-£3,000 is viable, especially with the 12-month warranty. For an older Mk5 example worth under £3,000, a used engine (£800-£1,500) or timing chain repair (£700-£1,200) may be more cost-effective.

• Vehicle worth under £3,500: consider used engine or repair
• Vehicle worth £4,000+: rebuilt engine with warranty is sensible
• Factor in overall condition - bodywork, suspension, interior wear

A Vauxhall Astra 17 CDTI engine replacement typically takes 2-3 working days for a specialist workshop, including removal of the old unit, fitting the replacement, and road testing. Main dealers may quote 3-5 days due to scheduling and OEM parts ordering.

• Supply-only delivery: next-day available across the UK
• Supply & fit: book a slot with your nearest specialist
• Express fitting available in some regions

The Astra 17 CDTI (A17DTE, 1.7-litre, 110hp) was fitted to Mk5 and Mk6 Astra models from 2004-2015 and is known for strong low-end torque and decent economy but has timing chain and EGR vulnerabilities. The later 1.6 CDTI (B16DTR, 2015-2021) is a Euro 6-compliant engine with better emissions performance and AdBlue on some variants, but it has its own known issues including wet belt degradation and EGR cooler failures.

• 17 CDTI: simpler emissions hardware but older design
• 1.6 CDTI: cleaner but more complex; wet belt service critical
• Both are popular diesel options; choose based on your Astra's generation

Used engines are cost-effective (£800-£1,500) but come with unknown service history and no warranty beyond the supplier's standard 30-90 days - risk of the same timing chain failure reoccurring. Rebuilt engines (£1,800-£3,000) include new timing chain components, piston rings, bearings, and a 12-month unlimited-mileage warranty, offering peace of mind.

• Used: best for low-budget repairs on lower-value vehicles
• Rebuilt: best for long-term ownership (2+ years) and higher-value Astras
• Always confirm what components were replaced in a rebuilt unit
