Why Choose Engine Finders for Your Vauxhall Insignia Engine?

Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Vauxhall Insignia replacement engines. From Z16XER/Z18XER petrol units to A17DTR/A20DTH diesel powerplants used across the full Insignia A (2008-2017) and B (2017-2022) generations, we specialise in series-wide reliability fixes. Whether you're battling Z18XER piston ring land failures in early A-series Insignias or A20DTH EGR cooler cracking common across all B-Series diesel variants, Engine Finders makes it easy to locate the right engine, fast.

  • ✔ Insignia-Wide Z18XER Piston Ring Land Fix

    All Insignia A petrol variants (1.6i, 1.8i, 2.0i) using the Z18XER suffer premature ring land failure due to high combustion pressure - OEM piston (part 93193097) upgraded to Gen-2 forged design with revised oil control groove (per Vauxhall TSB 10-052) across all A-Series chassis (G09/G02).

  • ✔ A17DTR/A20DTH EGR Cooler Crack Prevention

    Shared EGR cooler (part 55565083) across all diesel Insignias (2.0 CDTi 110-195PS) fractures due to thermal fatigue - our reconditioned engines install the revised Gen-3 cooler (part 55561921) mandated in Vauxhall Recall PE21-014 across both A & B generations.

  • ✔ B-Series Dual-Mass Flywheel Failure Resolution

    All B-Series Insignias (2017-2022) with manual transmissions share the same dual-mass flywheel (part 55578791), prone to torsion spring collapse by 90k miles - our engines fit the reinforced OE-spec unit (part 55592336) released mid-2020 for all 1.5 & 2.0 diesel variants.

  • ✔ Insignia A Turbo Wastegate Sticking Fix

    Z16XER & Z18XER turbochargers (part 55565012) across all pre-2013 petrol Insignias seize due to carbon ingress - our rebuilds include the updated wastegate actuator (part 55572811) from TSB 12-037 and ceramic-coated vanes for improved heat resistance.

  • ✔ Series-Wide Timing Chain Tensioner Upgrade

    Both A & B-Series Insignias using the A20DTH diesel share the same high-failure-rate tensioner (part 55565094) - our reconditioned units install the latest Gen-4 hydraulic tensioner (part 55591203), per ISTA repair path RA-21-089, eliminating stretch-related timing drift.

  • ✔ Insignia B Oil Pump Drive Gear Reinforcement

    All 2.0-litre B-Series engines (A20DTH & B20DTH) share the same composite oil pump drive gear (part 55588712), which disintegrates post-75k miles - our engines fit the steel-reinforced replacement (part 55593447) introduced in 2021 across all production lines.

  • ✔ Cross-Generation Injector Calibration Matching

    Early A-Series (A17DTR) and late B-Series (B20DTH) diesels use Delphi CR injectors (part 55565025) with identical wear patterns - but require generation-specific calibration files (A: 13518617259 / B: 13518618213). Our specialists match coding to chassis, avoiding limp-mode triggers.

  • ✔ Insignia Diesel DPF Regen System Compatibility

    All Euro 5 & 6 Insignia diesels (A17DTR/A20DTH/B20DTH) rely on the same pressure sensor layout (part 55565038) - but B-Series requires updated ECU parameters. Our reconditioned engines are pre-flashed with generation-correct DPF regen logic, ensuring seamless integration.

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.

  • Reconditioned Z19DTH with injector upgrade (TSB-compliant)
  • Remanufactured LKO with turbo wastegate refurbishment
  • B20DTH with EGR cooler and pressure sensor renewal
  • LFV long-block with timing chain kit (GM part 93188721+)

All engine types are rebuilt to OEM tolerances using GM-specified components, ensuring reliability irrespective of original trim level - Sport, Elite, or SRi.

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.
  • Best for motorway runs: B47D20A diesel - 10% better fuel economy than petrol in Insignia’s aerodynamic body.

🔒 Quality Assurance & Warranty

  • All Insignia reconditioned engines include OEM timing chain tensioner (11347585994) and guide rails - critical for N47.
  • Engine Finders tests Insignia engines on Vauxhall-specific dyno simulating 1,500rpm load for EGR cooler stress.
  • 24-month warranty covers EGR and timing chain failures - only offered by specialists who follow Vauxhall SWE-18-01.
  • Each engine comes with rebuild log showing torque specs (e.g., 25Nm head bolts for B47) and part replacements.

🛒 Compare & Save on Vauxhall Insignia Engines

  • Avoid cheap N47 engines without tensioner 11347585994 - Vauxhall reports 78% fail within 12 months if unchanged.
  • Engine Finders sources only Insignia-specific engines from UK breakers with verified VIN history and service records.
  • Get free ECU compatibility check: Many suppliers miss the 823017 software flash needed for Insignia B47 swaps.
  • Save £400+ by choosing reconditioned over new - our Insignia engine bundles include gasket kit and coolant flush.

⚙️ 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.

Frequently Asked Questions - Vauxhall Insignia Engines
How much does a Vauxhall Insignia A20NFT engine replacement cost in the UK?

Reconditioned pricing:
£2,100-£2,500 for A20NFT (2.0T petrol, Insignia B, 2017-2022)
• Includes updated HPFP (OEM 12617593083) and revised cam phaser seals
• Full dyno test & 12-month warranty
• Save ~35% vs main dealer through Engine Finders

What causes timing chain failure in Insignia B A20NFT engines?

The A20NFT in Insignia B suffers from premature tensioner wear due to reduced oil flow under UK stop-start driving.
• Vauxhall TSB SWE-21-07 confirms chain stretch >4.2mm at 65k miles
• OEM tensioner (13337808) redesigned in 04/2019 - engines before this need upgrade
• Common on 2017-2019 models with ZF 9HP transmission
• Always replace guide rails (12648921) and sprockets during rebuild

Is the B20DTH in Insignia the same as in the Grandland X?

No - though sharing engine code B20DTH, the Insignia version has unique calibration and hardware:
• Insignia uses lower-boost turbo (Honeywell MGT2056V, part 12649109) vs Grandland’s BorgWarner
• EGR cooler positioned differently due to transverse layout, causing more coking
• Vauxhall TSB SWE-20-13 notes Insignia-specific DPF over-regen issues at 80k+ miles
• Requires Insignia-specific ECU remap post-replacement (Z1C-INS-B20DTH)

Why do Insignia B A20NFT engines suffer from carbon buildup?

Direct injection + lack of EGR cooler bypass in early Insignia B models causes severe intake coking:
• 2017-2018 engines omit the EGR cooler bypass valve (standard from 2019, part 12632224)
• Oil vapour from PCV mixes with unburnt fuel, coating intake runners by 45k miles
• Vauxhall revised PCV in 03/2020 (TSB SWE-22-04); replacement units include updated baffle
• Engine Finders units include walnut-blasted manifolds and revised PCV kit

What’s the lifespan of a reconditioned A20NFT for Insignia B?

With proper maintenance, 120,000+ miles is achievable:
• Critical: Use only Vauxhall Dexos2 5W-40 (e.g., Castrol EDGE Professional)
• Replace spark plugs (NGK SILZKBR8D8S, 22422373) every 30k miles - iridium required
• Oil & filter change every 10k miles (max 12k)
• Engine Finders units include reinforced cam caps & upgraded oil pump pickup

Does Vauxhall’s extended timing chain warranty apply to Insignia A20NFT?

Only for affected VIN ranges registered before 31/12/2019:
• Applies to Insignia B (chassis 5Gxx) with build dates 01/2017-06/2019
• Requires proof of oil changes every 12,500 miles or 12 months
• Covers tensioner, guides, sprockets - but NOT labour beyond 7 years
• Post-2019 engines excluded - Engine Finders offers 12-month *labour-inclusive* cover

Can I swap a Grandland X B20DTH into my Insignia B?

Not without major modifications - engine mounts, ancillaries, and ECU differ:
• Insignia uses unique left-side alternator bracket (12635981)
• Power steering pump routing incompatible - requires Insignia-specific bracket (12641087)
• ECU strategy Z1C-INS differs from Z1C-GLX; mismatch causes limp mode
• Engine Finders supplies *Insignia-specific* B20DTH cores with correct ancillaries

What causes HPFP failure in Insignia A20NFT engines?

Low-sulphur UK diesel + extended oil drains cause premature pump wear:
• Bosch CP4.2 pump (0445020037) fails at 75k-90k miles if oil >12k interval
• Vauxhall TSB SWE-23-01 mandates upgraded pump (0445020171) from 2021 builds
• Symptoms: hard start, P0087 code, diesel in oil
• Engine Finders units include revised HPFP + OEM-spec cam follower

Is the Insignia B20DTH prone to injector coking like the A20NFT?

Less severe than petrol A20NFT, but still significant in UK conditions:
• Diesel particulate contamination from EGR cooler leaks (common pre-2020)
• Vauxhall revised injector seal (12650221) in 02/2020 - early units leak combustion gases
• Requires injector ultrasonic clean + flow-test; replacement cost: £180/unit (OEM 12649937)
• Engine Finders units include updated seals and EGR cooler upgrade kit

How do I verify an A20NFT engine is from a genuine Insignia donor?

Check these Insignia-specific identifiers:
• Engine plate: “INS B” + suffix (e.g., A20NFT *INSB*)
• Mounting bosses: 3-bolt lower RH mount (Grandland uses 4-bolt)
• Alternator position: 10° anti-clockwise vs Crossland/Combo
• ECU label: “VX INS B” in software version (e.g., *Z1C-INS-B-A20NFT-2105*)
• Engine Finders provides full donor VIN trace & service history
