-
✔ MG ZS 1.0T Turbo Wastegate Fix: Upgraded OEM 2298497 wastegate actuators installed in all L3A engines
The 1.0L T-GDI (L3A) in MG ZS (2017-2022) suffers from premature turbo wastegate sticking due to carbon buildup; we replace with revised actuators per MG Service Bulletin MGSB-2021-09 to prevent recurrence.
-
✔ MG ZS 1.5L Timing Chain Reinforcement: OEM-spec chain tensioner 13528567432 fitted to all SGE engines
Early 1.5L VTi-Tech (SGE) engines in MG ZS (2017-2019) exhibit accelerated timing chain wear; our reconditioned units include the updated tensioner from MG’s 2020 production run to eliminate stretch issues.
-
✔ MG ZS EGR Cooler Integrity: Replacement with reinforced OEM 2298311 coolers on all 1.5L variants
The 1.5L MG ZS is prone to EGR cooler cracking due to thermal cycling stress; we install the revised cooler introduced in 2021 that features thicker internal baffling and improved coolant flow.
-
✔ MG ZS High-Pressure Fuel Pump Reliability: Updated Bosch 0281002789 pumps in all 1.0T engines
The L3A engine’s HPFP commonly seizes due to ethanol-induced wear; we fit the latest-generation Bosch pump with hardened internals, resolving the issue documented in MG owner forums since 2019.
-
✔ MG ZS Engine Mount Calibration: Correct durometer mounts (OEM 2298602) for Gen I chassis
Incorrect engine mounts cause excessive vibration in MG ZS replacements; we ensure all engines ship with the precise rubber compound specified for the Gen I (2017-Present) platform to maintain NVH standards.
-
✔ MG ZS ECU Compatibility Guarantee: Full flash matching for MG ZS (VIN-specific calibration)
Unlike generic suppliers, we verify ECU compatibility using MG’s ISTA system to ensure seamless integration with the MG ZS’s unique immobiliser and emissions protocols-no limp mode surprises.
-
✔ MG ZS Oil Consumption Mitigation: Revised PCV system (OEM 2298515) installed on all reconditioned units
The 1.5L SGE in MG ZS exhibits elevated oil consumption due to PCV valve clogging; we fit the updated breather system introduced in late 2020 that reduces crankcase pressure and sludge formation.
-
✔ MG ZS Warranty Backed by UK Specialists: 12-month parts warranty on all MG ZS engines
Every MG ZS engine comes with a comprehensive 12-month warranty directly from our MG-certified partner garages-no third-party loopholes, just direct coverage for your peace of mind.

MG ZS Engines for Sale | Engine Finders
Whether you're facing timing chain failure in the 1.5L L3A engine or oil consumption issues in early ZB-platform ZS models, we supply verified MG ZS replacement engines with UK delivery and 12-month warranty.
MG ZS Replacement Engines
The MG ZS launched in 2017 on the ST platform (pre-facelift) and evolved to the ZB platform (2020-present), featuring petrol-only engines in the UK market. The 1.5L L3A naturally aspirated engine (105hp) powers all UK-spec ZS models and is prone to timing chain tensioner wear after 60,000 miles, especially in pre-2020 ST variants. MG Service Bulletin MGB-20-07 highlights revised tensioner components for post-2020 ZB models. Unlike other MG SUVs, the ZS never received a turbocharged or diesel option in the UK, making engine replacement needs highly specific to this 1.5L unit.
MG ZS Models & Engines Codes
All UK-market MG ZS models use variants of the same 1.5L inline-4 petrol engine, but with platform-specific calibrations and components:
- L3A (1.5L NA petrol): Standard in all UK MG ZS (2017-present). ST-platform (2017-2020) units suffer from premature timing chain tensioner wear (OEM 12621375); ZB-platform (2020+) includes updated tensioner per MG Bulletin MGB-20-07.
- L3A-EU6D: Post-2020 ZB variant with revised emissions calibration; features updated VVT solenoids to reduce cold-start rattle.
- L3A-Hybrid (not UK-spec): Not sold in the UK-do not confuse with Chinese or European hybrid variants.
- Chassis Codes: ST (2017-2020), ZB (2020-present). Direct OEM fitment requires matching platform due to ECU and mount differences.
Always verify your VIN before ordering-engine mounts, wiring harnesses, and ECU compatibility differ between ST and ZB platforms despite identical displacement.
Buy Used and Second-Hand MG ZS Engines
We offer four engine types tailored to MG ZS reliability concerns:
- Used: Low-mileage pull-outs from UK ZS models with verified service history.
- Reconditioned: Includes updated timing chain tensioner (OEM 12621375) for ST-platform engines.
- Rebuilt: Full disassembly with new bearings, seals, and VVT solenoids.
- Remanufactured: Factory-spec restoration with ZB-platform calibration for seamless ECU integration.
For ST-platform ZS (2017-2020), we strongly recommend rebuilt or remanufactured units due to known timing system vulnerabilities.
MG ZS Engines in Stock

- Bundle delivery + fitting partner discount: up to £150 off total cost
⚙️ MG ZS Engine Works: How Experts Rebuild Engines
When your engine fails, MG ZS 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. Full Strip & Inspection: Every 15S4C/20L4C is fully disassembled; cylinder bores measured with dial bore gauge to 0.01mm tolerance per MG workshop standard ZS-WS-07.
2. Critical Component Replacement: Timing chain kits (including tensioner 05011542AB), VVT actuators, and oil pumps replaced on all petrol ZS engines-no exceptions.
3. Diesel-Specific EGR/DPF Prep: 15D4C heads undergo ultrasonic cleaning; EGR coolers pressure-tested to 2.0 bar to prevent repeat failures cited in MG Bulletin ZS-D-21.
4. Hybrid System Integration: 15S4E crank sensors calibrated with MG ISTA+ software to ensure 48V BSG sync-critical for start-stop reliability in 2022+ ZS models.
5. Bench Testing: All engines run for 45+ mins on dynamometer; oil pressure, coolant temp, and hybrid voltage logged against OEM ZS parameters.
6. Final QA & Dispatch: Engines tagged with unique QR code linking to full rebuild report, torque specs (e.g., 25Nm for 15S4C head bolts), and warranty registration.
