Deepal S7 Service Schedule — EV and EREV Variants Covered

The Deepal S7 (Changan's premium EV brand) comes in two flavours: pure EV and EREV (range-extended). Service schedules differ significantly. EV is the simpler, cheaper option.

EV variant service interval

• First inspection: 3 months / 5,000 km
• Routine: every 12 months or 20,000 km
• Major: every 2 years / 40,000 km

EREV variant service interval

• First inspection: 3 months / 5,000 km
• Routine: every 12 months or 20,000 km
• Annual range-extender engine oil change (even if engine has barely run — oil acidifies on calendar)
• Major: every 2 years / 40,000 km

EV variant routine items

Every 12 months / 20,000 km

• Cabin air filter
• Brake fluid moisture test
• 12V auxiliary battery health check
• Tyre rotation and pressure (RWD on most trims)
• Brake pad wear inspection
• Wiper blade inspection
• Underbody and HV cable visual
• Software update check

Every 2 years / 40,000 km

• Brake fluid replacement (DOT 4)
• Reducer (gearbox) oil check (sealed)
• Coolant condition check

Every 4 years / 80,000 km

• A/C system service
• Suspension bushings inspection
• 12V battery replacement

EREV variant additional items

Everything from EV variant PLUS:

Every 12 months

• Range-extender engine oil + filter (~3.4 L of 0W-20 full synthetic)

Every 2 years

• Engine air filter replacement
• Range-extender coolant condition check (separate from battery loop)

Every 4 years

• Spark plugs (iridium)

Every 6-8 years

• Coolant flush both loops (engine pink + battery low-conductivity — NEVER mix)
• Fuel filter replacement (range-extender fuel system)

Cost comparison: EV vs EREV (5 years)

| Year | Deepal S7 EV | Deepal S7 EREV |

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

| 1 | €90-140 | €150-220 |

| 2 | €200-280 | €270-380 |

| 3 | €130-190 | €180-260 |

| 4 | €400-580 | €550-780 |

| 5 | €130-200 | €180-260 |

| Total | ~€950-1,390 | ~€1,330-1,900 |

EV variant is ~30-35% cheaper to maintain over 5 years. Trade-off: less total range.

Variant-specific quirks

• Single coolant loop (battery + electronics share)
• No engine to service
• Brake pads last 60,000-90,000 km thanks to regen

• Two coolant loops (engine + battery, never mix)
• Range-extender uses 0W-20 only (Atkinson-cycle generator)
• Brake pads last similarly long thanks to regen
• Annual oil change non-negotiable even at low engine running hours

Common mistakes

1. EREV owners skipping annual oil change because 'engine barely ran.' Oil acidifies on calendar.
2. Mixing the two coolant types on EREV.
3. Using 5W-30 in the EREV range-extender (calibrated for 0W-20).
4. Generic universal cabin filter.
5. Skipping 12V battery check.
6. Topping up brake fluid instead of full bleed every 2 years.

FAQ

Which Deepal S7 variant is cheaper to maintain?

The pure EV variant by ~30-35% over 5 years — no engine oil, no spark plugs, no engine air filter.

Does the EREV need annual oil change even if I drive mostly on battery?

Yes — oil acidifies on the calendar regardless of running hours. Never exceed 12 months.

What oil does the EREV 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 on both variants. Rear often lifetime.

Cheaper than a comparable petrol SUV?

EV variant: ~50-60% cheaper over 5 years. EREV variant: ~30-40% cheaper.
