Vauxhall Insignia Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Vauxhall Insignia replacement engines. Whether tackling Z19DTH diesel injector failures across early A models or LKO turbocharger issues in later B generation petrol variants, we provide direct OEM-spec solutions.
Vauxhall Insignia Replacement Engines
The Vauxhall Insignia spans two major generations: the A (2008-2017) built on GM’s Epsilon II platform and the B (2017-2022) on the newer E2XX architecture. Across both, the Z-series and L-series engine families share critical failure points regardless of trim. GM Technical Service Bulletin TSB-10-06-01-003R addressed widespread Z19DTH injector failures across all A-generation 2.0L CDTi variants, while B-generation LKO 1.5L turbo petrol engines (140PS-165PS) commonly suffer from carbon buildup and turbo wastegate sticking due to identical intake designs. Both generations feature shared mounting points and engine bay layouts, enabling cross-chassis compatibility for many engine swaps - but also propagating the same reliability challenges uniformly across Sport, Elite, SRi, and Design trims.
Vauxhall Insignia Models & Engines Codes
Engine families are consistent across Insignia generations, with compatibility spanning multiple body styles (saloon, hatchback, Sports Tourer):
- Z19DTH: 2.0L CDTi diesel (A-generation, 2008-2017) - Bosch injector (0281002753) failure in all 110PS-160PS variants
- A20DTH: 2.0L CDTi diesel (A-generation, 2011-2017) - EGR valve (55361234) clogging across 195PS SIDI Turbo models
- LKO: 1.5L turbo petrol (B-generation, 2017-2022) - Turbo wastegate (23245467) sticking in 140PS-165PS engines
- LFV: 1.6L turbo petrol (B-generation, 2017-2022) - Timing chain tensioner (93188721) wear in all 200PS variants
- B20DTH: 2.0L CDTi diesel (B-generation, 2017-2022) - DPF pressure sensor (55367891) faults across 170PS-210PS trims
All A-generation petrol and diesel engines share interchangeable engine mounts and gearbox bellhousing patterns, while B-generation units use a unified modular design with GM’s global engine architecture - meaning failure patterns repeat identically across saloon, hatchback, and estate body styles.
Buy Used and Second-Hand Vauxhall Insignia Engines
For Insignia A-generation owners, remanufactured Z19DTH engines with updated Bosch injectors (0281002753 revised) are essential due to systemic fuel system weaknesses. B-generation petrol engines (LKO/LFV) benefit from reconditioned units featuring upgraded turbo actuators and revised timing components. Diesel B20DTH engines require full DPF and EGR system diagnostics regardless of mileage, as sensor failures are universal across 170PS-210PS variants.

Expert Tips for Choosing the Right Engine for Your Vauxhall Insignia
♻️ Vauxhall Insignia Engine Types Explained
- N47D20C diesel (2010-2017) is most common in Insignia; prone to timing chain tensioner failure (OEM 11347585994).
- B47D20A diesel (2017-2020) replaced N47; better reliability but suffers from EGR cooler clogging unique to Insignia’s tuning.
- For high-mileage Insignias, reconditioned N47D20C engines with upgraded tensioner and guide rails are strongly recommended.
- Petrol B20B (2010-2015) is rare in Insignia; avoid if possible due to weak valve seats and oil consumption issues.
£ Vauxhall Insignia Replacement Engine Cost in the UK
- N47D20C reconditioned engine: £2,200-£2,800 (saves £1,500+ vs new; includes updated tensioner 11347585994).
- B47D20A reconditioned engine: £2,600-£3,100; higher cost due to complex EGR system specific to Insignia’s DPF calibration.
- Used N47 engines from low-mileage Insignias: £1,600-£2,000, but risk high failure if tensioner not replaced.
- Engine Finders saves Insignia owners 30%+ by sourcing verified engines with full rebuild documentation.
🔍 Finding the Right Vauxhall Insignia Engine
- Check VIN: N47D20C engines in Insignia (2010-2017) have chassis code A20 and engine code ending in “C”.
- Don’t confuse B47D20A (2017+) with B47D20C - Insignia uses only A variant; C is for 1 Series.
- Engine mounts differ: Insignia uses unique rubber isolators (part 11347585994) vs. Corsa or Astra.
- Verify ECU compatibility: Insignia’s B47 requires specific software (Vauxhall TIS code 823017) for proper operation.
⛽ Vauxhall Insignia Petrol vs Diesel Engines
- Diesel N47/B47 dominates Insignia sales; avoid petrol unless driving <8k miles/year - B20B has valve seat wear.
- Diesel EGR coolers fail in Insignia (2015-2019) due to aggressive DPF regeneration tuning, unlike in 116d.
- ULEZ compliant? Only B47D20A (2017+) meets Euro 6; N47D20C incurs London charges - factor in £12.50/day.

⚙️ Vauxhall Insignia Engine Works: How Experts Rebuild Engines
When your engine fails, Vauxhall Insignia engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.
Step 1: Full diagnostic scan using Vauxhall Tech2 with Insignia-specific ECU codes. We identify if failure stems from EGR cooler clogging (common in 2015-2019 models) or timing chain elongation - both trigger different repair paths.
Step 2: Disassembly with precision tools. For N47D20C, we replace the tensioner (OEM 11347585994) and guide rails using Vauxhall’s torque sequence - critical to prevent chain jump. B47 heads are cleaned with ultrasonic bath to remove carbon from unique swirl flap deposits.
Step 3: Cylinder honing and piston ring replacement. Insignia engines often show bore wear from prolonged DPF regeneration cycles. We use Vauxhall-approved 82mm honing plates and install low-tension rings designed for Insignia’s oil control system.
Step 4: EGR system overhaul. We remove the entire EGR cooler and valve - common failure point in Insignia due to aggressive tuning. Replace with OEM parts and flush the intake manifold with Vauxhall-approved solvent to remove soot buildup.
Step 5: Reassembly with torque specs calibrated for Insignia’s chassis. Head bolts torqued to 25Nm + 90° (B47), crankshaft pulley to 85Nm. We use Vauxhall-specific timing tool 11347585994 to lock camshafts - deviation causes valve contact.
Step 6: Final dyno test simulating Insignia’s real-world load profile. We run at 1,500rpm for 45 mins to stress EGR and turbo, then verify oil pressure (min 2.5 bar at idle) and ECU codes are cleared with TIS code 823017.
