Li Auto L7 EREV Maintenance Schedule — Service Guide

The Li Auto L7 is an EREV (Extended-Range Electric Vehicle) — it drives like an EV (the wheels are always electric-motor-driven) but has a small petrol generator on board to top up the battery. Maintenance is a hybrid of EV simplicity and ICE discipline.

Official Li L7 service interval

• First inspection: 3 months / 5,000 km
• Routine: every 12 months or 20,000 km
• Major: every 2 years / 40,000 km
• Range-extender oil change: every 12 months even if engine has barely run (oil acidifies on calendar, not mileage)

In hot climates (Middle East, parts of Latin America), reduce routine to 15,000 km.

What gets replaced at each interval

Every 12 months / 20,000 km (routine)

• Range-extender engine oil and filter — ~3.5 L of 0W-20 full synthetic. Even if engine has run only 1,000 km in hybrid mode, change annually.
• Cabin air filter
• Brake fluid moisture test
• 12V auxiliary battery health check
• Tyre rotation and pressure (heavy car, ~2,300 kg, eats tyres)
• Brake pad wear inspection
• Wiper blade inspection
• Underbody and HV cable visual
• Software update check

Every 2 years / 40,000 km

All routine plus:

• Brake fluid replacement (DOT 4)
• Engine air filter replacement
• Range-extender coolant condition check (separate from battery loop)
• Battery loop coolant condition check (low-conductivity, NEVER mix with engine coolant)

Every 4 years / 60,000 km

• Spark plugs (iridium, range-extender engine)
• A/C system service
• Suspension bushings inspection
• 12V battery replacement (preventative)

Every 6-8 years

• Coolant flush both loops
• Brake disc inspection
• Fuel filter replacement (range-extender fuel system)

EREV-specific quirks

• Two coolant loops: range-extender engine (standard pink coolant) + battery/electronics (low-conductivity). Never mix.
• No transmission service: wheels driven by single-speed reducers per axle. Sealed.
• Brake pads last 60,000-90,000 km thanks to regen handling most deceleration.
• Range-extender engine runs only at optimal RPM as a generator, never drives wheels directly. Fewer load cycles than typical PHEV engines.
• Heavy car: ~2,300 kg kerb weight. Front tyres wear faster, expect 30,000-40,000 km on fronts.

Year-by-year cost (EU averages, 2026)

| Year | Mileage | Service | Cost |

|------|---------|---------|------|

| 1 | 20,000 km | Routine + range-ext oil | €150-220 |

| 2 | 40,000 km | + brake fluid + engine air filter | €260-360 |

| 3 | 60,000 km | Routine | €160-230 |

| 4 | 80,000 km | Major: oil + plugs + 12V + A/C | €480-680 |

| 5 | 100,000 km | Routine + likely 12V | €180-260 |

5-year total: ~€1,230-1,750. Comparable petrol luxury SUV: €3,800-5,200.

Common mistakes

1. Skipping range-extender oil change because 'the engine barely runs.' Oil acidifies on calendar.
2. Mixing the two coolant types.
3. Using 5W-30 in the range-extender engine. It's calibrated for 0W-20.
4. Skipping 12V check (EREVs are hard on 12V due to constant electronics load).
5. Ignoring tyre rotation on a heavy car.

FAQ

How often should I service the Li L7 EREV?

Every 12 months / 20,000 km. Range-extender oil annually even if engine barely ran.

What oil does the range extender take?

0W-20 full synthetic, API SP. Never substitute 5W-30.

How long do brake pads last?

Front 60,000-90,000 km. Rear often lifetime of car.

Cheaper than a comparable petrol SUV?

Yes — ~60-70% cheaper over 5 years. EV simplicity plus efficient range-extender.

Does the EREV need transmission service?

No — sealed single-speed reducers per axle.
