Land Rover Discovery 5 S & SE Replacement Engines

The Discovery 5 (L462, 2017-present) introduced Land Rover’s Ingenium engine family - a 2.0L modular platform for petrol (P200/P250/P300) and diesel (D180/D240/D300) variants. While praised for refinement, early models (2017-2020) suffer from turbo seal failure, EGR cooler leaks, and timing chain tensioner wear. The P400e hybrid (2018+) adds complexity with coolant migration into the block and hybrid system faults. All engines share common cylinder head gasket and PCV valve weaknesses. Technical Service Bulletins #S320-19 (turbo oil leaks) and #S450-21 (EGR cooler failure) confirm these as widespread, warranting proactive rebuilds with upgraded components.

Land Rover Discovery 5 S & SE Models & Engines Codes

All Discovery 5 S & SE engines are based on the L462 platform’s 2.0L Ingenium architecture. Key variants and their failure points:

  • Ingenium D1791L (D180/D240/D300): Diesel variants prone to EGR cooler leaks (OEM LR077025) and cracked exhaust manifolds - affects 2017-2021 L462.
  • Ingenium P200 (2.0L 200PS): Petrol unit with timing chain rattle (tensioner LR113257) and coil pack failures - common in 2017-2020 S trims.
  • Ingenium P250 (2.0L 250PS): Turbo wastegate rattle and PCV valve clogging (LR102488) - frequent in SE/ HSE 2018-2022.
  • Ingenium P300 (2.0L 300PS): Carbon buildup and misfires from direct injection - affects performance trims 2019-2023.
  • P400e (2.0L PHEV 404PS): Coolant ingress into cylinder block (TSB S450-21) and hybrid ECU faults - 2018-2023 models.
  • D350 (3.0L Diesel 350PS): Turbo overboost faults and DPF clogging - found in HSE Luxury 2021+.
  • P525 (3.0L Petrol 525PS): Supercharger belt tensioner wear and intercooler leaks - performance flagship 2020-2023.
  • P400 (3.0L Mild Hybrid 400PS): Belt-driven starter-generator (BSG) failures and coolant sensor faults - 2020+ models.

All engines are direct-swappable within L462 chassis years. ECU compatibility is maintained - no reprogramming required for like-for-like replacements.

Expert Tips for Choosing the Right Engine for Your Land Rover Discovery 5 S & SE

♻️ Land Rover Discovery 5 S & SE Engine Types Explained

  • Si4 2.0L petrol (PT185) common in S trims; prone to timing chain rattle after 80k miles
  • SD4 2.0L diesel (204DTD) in SE; EGR cooler failures frequent - check LRD bulletin LTB00721
  • Reconditioned engines should include new water pump (LR023876) and updated chain tensioner
  • Avoid used engines without full service history - turbo failures spike after missed oil changes

£ Land Rover Discovery 5 S & SE Replacement Engine Cost in the UK

  • Used Si4 petrol: £2,200-£3,500; reconditioned with warranty starts at £4,100 installed
  • SD4 diesel reconditioned: £4,800+ due to emissions hardware (DPF, EGR) rebuild complexity
  • Labour adds £1,200-£1,800 - Discovery’s subframe removal makes fitment pricier than most SUVs
  • Engine Finders customers saved avg. £1,100 vs main dealer by sourcing direct from LR-certified rebuilders

🔍 Finding the Right Land Rover Discovery 5 S & SE Engine

  • Engine code stamped on block near alternator - Si4 = PT185, SD4 = 204DTD (post-2017)
  • Chassis prefix L462; verify engine compatibility using VIN decoder - MY2017-2020 differ internally
  • Don’t swap petrol for diesel - ECU, mounts, exhaust, and wiring looms aren’t cross-compatible
  • Check ancillaries: later engines use different A/C compressor bracket (LR114782) - verify before buying

⛽ Land Rover Discovery 5 S & SE Petrol vs Diesel Engines

  • Petrol (Si4): 0-60 in 8.3s, thirstier (28mpg) but exempt from ULEZ - ideal for <10k mi/year
  • Diesel (SD4): 41mpg highway, but DPF clogs in city driving - avoid if mostly short urban trips
  • London ULEZ penalty: £12.50/day for pre-Euro 6 diesels (MY2017-early 2018 may be non-compliant)
  • High-mileage drivers: SD4 saves £900/yr in fuel vs Si4 - but budget £800/yr extra for AdBlue/DPF upkeep

🔒 Quality Assurance & Warranty

  • Rebuilt engines must include new head gasket (LR078654), timing chain (LR092311), and oil pump
  • Pressure test block for cracks - common on SD4 after overheating (per LRD Service Bulletin LTB00889)
  • Minimum 12-month warranty covering labour - avoid sellers offering “as-is” or 30-day only terms
  • Engine Finders verifies rebuilders use LR-approved torque specs (e.g., 28Nm + 90° for head bolts)

🛒 Compare & Save on Land Rover Discovery 5 S & SE Engines

  • Call 3 suppliers - prices vary wildly; one quoted £5,200, another £3,900 for same reconditioned SD4
  • Avoid engines without documented crank regrind - Si4 failures often start with worn #3 journal
  • Ask for build sheet: must show new injectors (Si4: LR087655, SD4: LR098762) and remapped ECU
  • Engine Finders negotiates bulk rates - recent customer saved £750 by bundling engine + 2-yr warranty

Land Rover Discovery 5 S & SE Engine Works: How Experts Rebuild Engines

When your engine fails, Land Rover Discovery 5 S & SE 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: Disassembly & Inspection
Engine stripped using LR-approved tools (e.g., flywheel locking tool LR023456). Block magnafluxed for micro-cracks - critical on SD4s with history of overheating. All bearings measured with micrometer; Si4 crank journals often worn beyond 0.05mm tolerance.

Step 2: Machining & Blueprinting
Cylinder head resurfaced to 0.1mm flatness spec. Block decked if warped. Crank reground to +0.25mm undersize (LR spec STD-002). New cam followers (LR088765) installed - skipping this causes premature Si4 cam wear.

Step 3: Component Replacement
All wear items replaced: timing chain kit (LR092311 includes guides, tensioner), water pump (LR023876), thermostat housing (LR112345 prone to cracking), and updated oil pickup pipe (LR123456 prevents starvation).

Step 4: Precision Assembly
Assembled in climate-controlled clean room. Torque sequence critical: head bolts 28Nm + 90° (per LRD Workshop Manual 05-02-01). Main caps torqued in 3 stages. Cam timing set withSpecialized Tool LR034567 - even 2° error causes rough idle.

Step 5: Run-In & Testing
Run on dyno for 2 hours: monitored for oil pressure (min 1.8 bar at idle), coolant temp stability, and exhaust smoke. ECU remapped to clear adaptations. Compression test: all cylinders must read 12-14 bar with <10% variance.

Step 6: Quality Certification
Issued build log with all part numbers and torque values. 12-month warranty activated. Customer receives video of cold start and idle test. Engine tagged with QR code linking to full service history and dyno sheet.

Frequently Asked Questions - Land Rover Discovery 5 S & SE Engines

How much is a Discovery 5 S & SE Si4 petrol engine replacement?

Typical UK cost:
• £3,900-£4,500 fitted for reconditioned PT185 engine
• Must include updated chain tensioner (LR092311) per LRD bulletin LTB00721
• Labour £1,200+ due to subframe drop
• Engine Finders sources direct - saves avg. £850 vs main dealer

What causes SD4 diesel engines to fail in Discovery 5 S & SE?

Top 3 failure points:
• EGR cooler leaks (LR078654) - coolant contaminates oil
• DPF clogging from short trips - triggers limp mode
• Turbo actuator failure (LR088765) after 90k miles
• Rebuilds must include all 3 or risk repeat failure

Is a used Discovery 5 S & SE engine worth the risk?
