Service and maintenance intervals
Service and maintenance intervals
The service interval depends on the exact vehicle, equipment, operating conditions and current service configuration. Treat the oil service and inspection dates separately.
Fixed interval and LongLife
| Regime | How the date is determined | Important |
|---|---|---|
| Fixed interval | A predetermined time and mileage; whichever limit is reached first. | Uses a fixed service display and the corresponding oil regime. |
| LongLife / flexible | The vehicle calculates the oil-service date from operating data, subject to the manufacturer’s maximum limit. | LongLife oil alone neither activates the regime nor automatically extends the interval. |
What QI and QG codes mean
QI codes are PR codes for the service display. These are code meanings, not J&S SERVIS recommendations:
QI
| Code | Service display |
|---|---|
| QI0 | Without a service display. |
| QI1 | Fixed: 5,000 km or 1 year. |
| QI2 | Fixed: 7,500 km or 1 year. |
| QI3 | Fixed: 10,000 km or 1 year. |
| QI4 | Fixed: 15,000 km or 1 year. |
| QI6 | Flexible service; the vehicle calculates the date, no later than the manufacturer limit for the exact version. |
QG codes mainly occur in older documentation. Their use changed by production period, so they cannot establish a current service plan without context:
QG
| Code | Meaning in older documentation |
|---|---|
| QG0 | Without extended service intervals. |
| QG1 | With extended service intervals (LongLife). |
| QG2 | Without the option to activate an extended interval. |
Newer vehicles distinguish the service regime with QI codes; QG may describe other equipment such as an oil sensor. Use the data sticker, VIN, documentation and actual vehicle configuration.
Where to find my service interval
- Vehicle data sticker
- PR codes may appear on the vehicle data sticker or in service documentation. Form and location are not identical on every vehicle.
- VIN and manufacturer catalogue
- The complete VIN can identify the production version and matching service plan.
- Current vehicle setting
- The instrument panel or infotainment shows the currently configured due date. It does not prove that a previous recoding was correct.
Options for changing the interval setting
- First verify that the manufacturer permits both fixed and flexible regimes for the exact vehicle.
- Use oil approved for the selected regime and engine.
- Recode the service display diagnostically under the manufacturer procedure; merely resetting it need not change the regime.
- Record the change and new due date in the service history.
- When changing the service regime, do not exceed any binding time or mileage limit specified by the manufacturer.
Servicing electric and hybrid vehicles
| Model group | Engine oil | Service and exceptions |
|---|---|---|
| MEB battery-electric vehicles: Volkswagen ID., Škoda Enyaq/Elroq, CUPRA Born/Tavascan, Audi Q4 e-tron | No combustion engine and therefore no engine-oil change. | For example, Škoda Enyaq / Enyaq Coupé and the corresponding Volkswagen ID. models require a regular service inspection no later than every 2 years, without a mileage limit. The exact vehicle service schedule governs; individual operations can have their own interval. |
| Other Audi battery-electric vehicles: e-tron / Q8 e-tron and e-tron GT | No combustion-engine oil service. | Design differs from MEB; use the exact model plan. Gear fluids and cooling circuits are not engine oil. |
| Plug-in hybrids: GTE, eHybrid, TFSI e, iV and e-HYBRID | Have a combustion engine; its oil and filter follow the prescribed regime. | High-voltage tasks are separate. Frequent cold combustion-engine use can justify the shorter recommended interval. |
| Mild hybrids and other hybrids with a combustion engine | Engine-oil changes remain necessary. | Electrification does not cancel oil service. The exact engine, VIN and service plan govern. |
A model name or electric drive does not define a universal interval. Verify exceptions for production period, market, powertrain, equipment and service actions by VIN.
Oil change versus service inspection
| Regime | Important |
|---|---|
| Oil service | Engine-oil and oil-filter replacement, with its own date based on regime, engine and operation. |
| Service inspection | Vehicle checks and other prescribed work. Its date can differ from the oil service. |
| Separate operations | Brake fluid, filters, spark plugs, transmissions, all-wheel drive and other items can have their own time or mileage conditions. |
Completing one operation does not automatically complete the others. Each applicable date must be recorded and configured correctly after service.
