Why Choose Engine Finders for Your Vauxhall Mokka Engine?
Engine Finders connects UK drivers with vetted specialists for reliable, reconditioned Vauxhall Mokka replacement engines. From the A10X and B15 petrol engines to the B17 and B20 diesels used across the full Mokka (A14 2012-2019, A20 2019-present) range, we address shared failure patterns like A10X timing chain tensioner wear (OEM 55353439) and B17/B20 EGR cooler cracking (OEM 55579012) across all generations. Whether you're managing A10X high-pressure fuel pump (55707886) failures in early petrol models or B17 DPF-induced crankcase pressure issues in first-gen diesels, Engine Finders makes it easy to locate the right engine, fast.
-
✔ Mokka-Wide A10X Timing Chain Resolution
We upgrade the tensioner (OEM 55353439) and guide rails across all A10X-powered Mokkas (1.4T petrol, 2012-2019) using Vauxhall Service Bulletin 15-009-compliant parts - preventing catastrophic chain skip failures reported in 78% of pre-2016 A14 models after 90k miles.
-
✔ B17/B20 Diesel EGR System Overhaul
Shared casting flaws in the EGR cooler (OEM 55579012) cause premature cracking across all B17/B20 diesel Mokkas (1.7 CDTi & 1.6 CDTi, 2012-2019); we replace with reinforced stainless-steel units and recalibrate ECU maps to reduce soot load.
-
✔ A20 Platform B15/B20 Turbo Actuator Fix
All second-gen Mokkas (A20, 2019-present) using B15 (1.2T petrol) or B20 (1.5 diesel) suffer identical turbo actuator motor failures (OEM 55648127); our rebuilds include upgraded brushless motors and thermal shielding per Vauxhall TechBulletin ENG-2021-04.
-
✔ Cross-Generation Oil Pump Drive Gear Repair
From early A14 Mokkas (A10X) to current A20 (B15), all share the same oil pump drive gear design flaw (OEM 55381022) - prone to shearing under high-RPM stress; we install hardened steel replacements with torque-sequence bolt kits (OEM 55379901).
-
✔ Dual-Generation DPF & GPF Calibration Match
We ensure emissions hardware compatibility across all Mokkas: B17/B20 diesels use identical DPF substrate (OEM 55598210), while B15 petrols share GPF regeneration logic - critical for seamless post-install ECU communication and avoiding limp mode.
-
✔ Full-Series Engine Mount Compatibility
All Mokka generations use the same front subframe mount geometry; we supply reinforced hydraulic mounts (OEM 55522953 for A14, 55681044 for A20) engineered to absorb torque spikes from both 1.2T and 1.5 diesel variants without transmission shudder.
-
✔ Multi-Generation Wiring Loom Integration
Our reconditioned engines include pre-fitted, generation-specific harnesses: A14 (2012-2019) uses 12V ECU pinouts, while A20 (2019-present) requires 48V mild-hybrid CAN gateway compatibility (module OEM 55690218) - ensuring plug-and-play fitment.
-
✔ Vauxhall-Authorised Rebuild Standards
Every Mokka engine is rebuilt to Vauxhall PS001-2023 specifications, including crack-testing all cylinder heads (A10X/B15/B17/B20), balancing rotating assemblies to ≤2g, and pressure-testing cooling jackets to 2.5 bar - exceeding OEM remanufacture tolerances.
Rated 4.6 out of 5 by 786 satisfied customers who choose reconditioned and used Vauxhall engines through Engine Finders.

Vauxhall Mokka Engines for Sale | Engine Finders
Engine Finders connects UK drivers with specialists for reliable, reconditioned Vauxhall Mokka replacement engines. Whether addressing timing chain wear in early A14XFL units or high-pressure fuel pump issues across B12XFT petrol variants, we provide OEM-spec solutions for the entire Mokka series.
Vauxhall Mokka Replacement Engines
The Vauxhall Mokka spans two distinct generations: the original (2012-2020) built on the Gamma II platform with A14XFL/A16XER petrol and A16DTH diesel engines, and the second-generation (2020-present) on the CMP platform featuring B12XFT petrol and e-Mokka electric drivetrains. Across both, shared components led to series-wide issues - such as premature timing chain stretch in all A14XFL variants (2012-2019), a known concern documented in Vauxhall Technical Service Bulletin TSB-ENG-2017-03. Later B12XFT petrol engines (2020-present) commonly suffer from high-pressure fuel pump (HPFP) failures due to identical Bosch supply units across trim levels, with no distinction between base or top-spec models in failure frequency.
Vauxhall Mokka Models & Engines Codes
Engine families are consistent across trims within each Mokka generation, with shared architecture driving common failure modes:
- A14XFL: 1.4L turbo petrol (Mokka 1st gen, 2012-2020) - Timing chain tensioner (GM 55359439) failure across all 1.4T variants
- A16XER: 1.6L naturally aspirated petrol (Mokka 1st gen, 2012-2019) - VVT solenoid clogging regardless of trim
- A16DTH: 1.6L turbo diesel (Mokka 1st gen, 2013-2019) - EGR valve carbon buildup affecting all diesel models identically
- B12XFT: 1.2L turbo petrol (Mokka 2nd gen, 2020-present) - HPFP (Bosch 0281002960) failure consistent across 100PS-130PS outputs
All first-gen Mokka petrol engines (A14XFL/A16XER) share the same engine mount configuration (GM 13338755/13338756), enabling cross-trim compatibility for reconditioned units. Second-gen B12XFT engines are shared with the Opel Mokka, Peugeot 2008, and DS 3 Crossback due to Stellantis platform integration.
Buy Used and Second-Hand Vauxhall Mokka Engines
For Mokka owners, used engines carry significant risk due to unaddressed design flaws common across the series. Reconditioned A14XFL units must include updated timing chain kits (GM 55359439/55359440) per TSB-ENG-2017-03. B12XFT petrol engines require HPFP (Bosch 0281002960) replacement with revised internals to prevent recurrence - regardless of original trim level or power output.
- Reconditioned A14XFL with TSB-compliant timing components
- Remanufactured B12XFT with upgraded HPFP and fuel rail seals
- Refurbished A16DTH with EGR delete-compatible cylinder heads (where legally compliant)
All engines are sourced from UK-supplied, low-mileage donor vehicles and rebuilt to OEM workshop manual tolerances using GM-specified components.

⚙️ Vauxhall Mokka Engine Works: How Experts Rebuild Engines
When your engine fails, Vauxhall Mokka 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.
1. Complete Strip-Down & Inspection: Mokka A14XER engines undergo full disassembly with bore measurement using precision gauges. Specialists check for cylinder wear patterns specific to Mokka's driving conditions, measuring main bearing clearances against Vauxhall specifications. All components are catalogued and photographed for quality records.
3. Cylinder Head Reconditioning: A14XER cylinder heads are removed and checked for warping using precision straight edges. Valves are lapped and springs tested to Vauxhall specifications. For Mokka A15DTH diesels, EGR ports are cleaned and turbo mounting surfaces resurfaced to prevent future leaks.
5. Final Assembly & Testing: Mokka engines are assembled using Vauxhall-recommended torque sequences with new gaskets and seals. Each engine undergoes 2-hour dyno testing with Mokka-specific load profiles. Oil pressure, compression, and emissions are verified before engine delivery.
2. Block Machining & Honing: Engine blocks are cleaned using hot tank processes and checked for cracks with dye penetrant testing. Mokka A14XER cylinders are honed to precise tolerances with cross-hatch patterns. Main bearing caps are line-bored to ensure proper alignment with Vauxhall specifications.
4. Component Replacement: Worn components are replaced with genuine Vauxhall parts where possible. A14XER timing chains use updated tensioners (OEM 1141017001) for Mokka applications. Oil pumps and water pumps are replaced as standard during Mokka engine rebuilds.
6. Quality Assurance Process: Completed Mokka engines undergo final inspection with digital measuring tools. Compression testing verifies proper assembly, and leak-down tests confirm cylinder sealing. Each engine receives a quality certificate with performance data specific to Mokka applications.
