Why is this important?
| Component | Consequences of ignoring |
|---|---|
| Friction discs (DSG) | Lining wear → clutch slipping → jerking → complete clutch failure |
| Mechatronic unit | Dirty oil clogs solenoids → incorrect shifts → limp mode |
| Valve body (ZF) | Wear products block channels → oil pressure drops → shift delays |
Cost comparison:
| Timely service | Repair when ignored |
|---|---|
| DSG oil change: 600 PLN | Mechatronic replacement: 4000-8000 PLN |
| Adaptation: 200 PLN | Clutch + flywheel: 7500+ PLN |
Rule: every 10,000 km without oil change = minus 5000-10000 km of transmission life.
Tips
- Don't believe in 'lifetime' oil
- Change oil every 40-60k km
- Avoid jerking and hard starts
