77 kWh Battery (Rear-wheel drive)
Electric
Cycle through the infotainment screen while driving to check for any software lag or screen freezes, as early software versions occasionally exhibit glitches that benefit from a dealer update.
Listen carefully for any subtle suspension knocks or creaks over speed bumps, as the Q4's weight can place extra demand on control arm bushings over time.
Verify the charging port door latch operates smoothly and seals firmly, as debris accumulation can sometimes affect the electronic locking mechanism.
Check the condition of the regenerative braking transition; ensure the pedal feel remains consistent and predictable when lifting off the accelerator, as minor calibration discrepancies are worth noting.
Initial brake fluid flush and cabin air filter replacement.
Consider checking condition of the drive battery cooling system and coolant levels.
General chassis and steering component inspection to ensure continued handling precision.
Rotate your tyres every 10,000km, as the instant torque and vehicle weight can lead to faster rear tyre wear.
Keep your charging cable and port contacts clean to ensure efficient power transfer.
Maintain the software by checking for over-the-air updates or visiting your Audi dealer for routine system optimizations.
Use high-quality washer fluid to keep the front-facing camera and sensor arrays clear for safety systems.
Ensure your 12V auxiliary battery is tested during annual service, as this powers the car's electronics and is essential for reliable startups.
Estimated repair costs if issues arise
Future Budget Planning: Because the Q4 is a heavy EV with rear-wheel drive, the rear tyres tend to wear faster than the fronts. Depending on your driving style, you might eventually need to budget for a set of EV-specific tyres to maintain range and grip.
Future Budget Planning: Since the car uses regenerative braking, the mechanical brake discs get used less, which can sometimes lead to surface corrosion if the car is parked for long periods. You might eventually need to budget for a full disc and pad service if they show signs of pitting.
Future Budget Planning: While generally reliable, advanced electronic modules can be expensive to replace once the factory warranty expires. It is wise to set aside a small contingency fund for specialized diagnostics or control unit software updates.
