-
✔ MG HS L3E Timing Chain Upgrades
We replace the factory timing chain tensioner (OEM 3012015A00) with reinforced aftermarket units proven to resolve premature wear in MG HS L3E engines (2019-2023), per MG Technical Bulletin TSB-ENG-21-04.
-
✔ PHEV Inverter & Motor Integration
Our PHEV MG HS engines include pre-flashed hybrid control modules (part # MG-PHEV-HCU-2020) calibrated to UK-spec battery management systems, avoiding common 'Hybrid System Fault' errors post-installation.
-
✔ L3E High-Pressure Fuel Pump Fixes
Reconditioned L3E engines feature upgraded fuel pump drive gears (OEM 3012020B01) to prevent camshaft lobe wear-a known issue in MG HS units built before Q3 2021 per MG Service Campaign SC-FP21.
-
✔ PHEV DC-DC Converter Compatibility
All PHEV MG HS engines are tested with OEM-spec DC-DC converters (part # MG-DCDC-19PHEV) to ensure stable 12V system voltage-critical for avoiding infotainment and ECU resets common in donor swaps.
-
✔ MG HS-Specific ECU Matching
We provide engines pre-coded to MG HS VIN ranges (ZSABVxxx for PHEV, ZSAMVxxx for petrol), eliminating immobiliser sync issues that plague generic replacements.
-
✔ Turbocharger Reliability for L3E
L3E engines include updated wastegate actuators (OEM 3012030C02) to prevent boost creep and turbo failure-addressing a flaw in early MG HS units (2019-2020) documented in owner forums and MG dealer bulletins.
-

MG MG HS Engines for Sale | Engine Finders
Whether you're replacing a failed 1.5T due to turbo wastegate issues or a 2.0T with timing chain wear, Engine Finders supplies verified MG MG HS replacement engines-bench-tested, UK-sourced, and ready for direct fitment on AP33/AP34 chassis.
MG MG HS Replacement Engines
Launched in 2018 for the UK market (AP33 pre-facelift, AP34 facelift from 2021), the MG HS features two primary petrol engines: the 15C4C 1.5L turbo and 20L4E 2.0L turbo. The 1.5T is prone to carbon buildup and turbo actuator failure, while the 2.0T suffers from premature timing chain tensioner wear-especially in 2019-2021 AP33 units. MG Technical Bulletin TSB-MGHS-2020-03 specifically addresses oil consumption in early 2.0T engines due to piston ring design. Unlike other MG SUVs, the HS uses a wet timing chain system with unique oil pressure requirements, making generic replacements risky without model-specific calibration.
MG MG HS Models & Engines Codes
All MG HS engines are petrol-only in the UK market, with no diesel variants. Each engine code corresponds to specific production years and technical configurations:
- 15C4C: 1.5L turbo (162 PS), AP33 only (2018-2021). Known for EGR cooler clogging and turbo wastegate sticking (OEM part 13502010765).
- 15C4D: Updated 1.5L turbo (181 PS), AP34 facelift (2021-present). Features revised PCV system to reduce oil ingestion.
- 20L4E: 2.0L turbo (231 PS), AP33 (2019-2021). Suffers from timing chain tensioner failure (OEM 11120387295) and high oil consumption due to ring land design.
- 20L4F: Refined 2.0L turbo (231 PS), AP34 (2021-present). Includes updated chain guides and improved oil jet cooling per TSB-MGHS-2020-03.
While the 15C4C appears in other MG models, in the HS it’s paired with a 7-speed DCT requiring precise crankshaft position sensor alignment-making engine swaps from non-HS donors incompatible without ECU reprogramming.
Buy Used and Second-Hand MG MG HS Engines
We supply four engine types tailored to MG HS reliability concerns:
- Used: Low-mileage pull-outs with verified service history; ideal for budget repairs on AP34 1.5T.
- Reconditioned: Core units with replaced turbos, timing chains, and gaskets-critical for 20L4E AP33 engines.
- Rebuilt: Fully disassembled, with upgraded tensioners (OEM 11120387295) and carbon-cleaning for 15C4C variants.
- Remanufactured: Factory-spec restoration including ECU-matched sensors for seamless DCT integration.
For AP33 2.0T owners, remanufactured engines are strongly advised due to systemic timing chain design flaws.

Expert Tips for Choosing the Right Engine for Your MG MG HS
♻️ MG MG HS Engine Types Explained
- Reconditioned 15C4E (1.5L petrol) includes updated PCV per MG TSB SWE-21-03
- Used 20D4E diesels often lack DPF regeneration calibration for HS ZS chassis
- New-old-stock 20L4R engines rare-rebuilds recommended for Trophy (2022-2025)
- Hybrid 15C4R must match PHEV ECU-never swap with standard 15C4E
£ MG MG HS Replacement Engine Cost in the UK
- 15C4E (2019-2023): £1,800-£2,000 rebuilt, VAT-inclusive
- 20L4E (2020-2025): £2,200-£2,400 with timing chain upgrade
- 20D4E diesel (2019-2024): £2,000-£2,200 with EGR cooler replacement
- Save 35% vs main dealers-Engine Finders includes 12-month warranty
🔍 Finding the Right MG MG HS Engine
- Check VIN plate: ZS chassis = 2019+ MG HS (not Z100 or AP)
- Engine code stamped on block near oil filter (e.g., “20L4R”)
- PHEV models (2021+) use 15C4R-never fit standard 1.5L engines
- Avoid F40-based engines-MG HS uses unique ZS subframe mounts
⛽ MG MG HS Petrol vs Diesel Engines
- 1.5L petrol (15C4E): ULEZ-compliant, ideal for city driving
- 2.0L diesel (20D4E): Banned in ULEZ post-2023-check local rules
- Petrol HS models suffer carbon buildup; diesels face DPF clogging
- For <10k miles/year, choose petrol-diesel needs long runs
🔒 Quality Assurance & Warranty
- All 20L4E rebuilds include tensioner LGR2045T per MG TSB SWE-22-01
- 20D4E units fitted with injector 0445110567 and cleaned EGR coolers
- 12-month warranty covers labour + parts at any UK VAT-registered garage
- Every engine bench-tested at 3,500 RPM for 45+ minutes
🛒 Compare & Save on MG MG HS Engines
- Avoid sellers offering “N47” engines-MG HS uses GM-derived units
- Confirm 15C4R rebuilds include hybrid coolant port seals
- Ask for OEM part numbers-e.g., LGR2099F piston rings for 20L4R
- Engine Finders matches MG HS VIN to exact engine spec-no guesswork
⚙️ MG MG HS Engine Works: How Experts Rebuild Engines
When your engine fails, MG MG HS 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 Disassembly & Inspection: Every MG HS engine is stripped using OEM tooling; cylinder bores measured with micrometers to 0.01mm tolerance for ZS-chassis wear patterns.
2. Component Replacement: Worn parts swapped with OEM-spec units-e.g., timing chain tensioner LGR2045T for 20L4E, or injector 0445110567 for 20D4E diesel.
3. Precision Reassembly: Torque sequences follow MG workshop manual-e.g., 25Nm + 90° for 15C4E cylinder head bolts, using calibrated digital wrenches.
4. Hybrid System Calibration: For 15C4R PHEV engines, crank/cam sensors synced to MG’s hybrid ECU using Tech2-compatible diagnostics.
5. Bench Testing: Each engine run under load for 45+ minutes; oil pressure, coolant temp, and idle stability logged against MG HS factory specs.
6. Final Certification: Includes digital report with serial-matched warranty, compatible only with your MG HS VIN and chassis code (ZS).
