Common Issues to Check

• DSG/S Tronic gearbox issues: Some owners report mechatronic unit failures or rough shifts, particularly in higher mileage models. A full service history showing gearbox oil changes is crucial.
• Electrical gremlins: Infotainment system glitches, sensor failures, or warning lights can occur. Ensure all electrical systems are fully functional during inspection.
• Timing chain wear (petrol engines): Particular to some earlier 2.0 TFSI engines, inspect for rattling noises on start-up. Later models and regular oil changes help mitigate this.
• AdBlue system malfunctions (diesel engines): Issues with the AdBlue injector or tank can lead to warning lights and potential limp mode. Check service records for any related repairs.
• Suspension components: Wear and tear on bushes and linkages can lead to knocking noises, especially on models with sport suspension. Listen for unusual noises during a test drive.

Running Costs

• Fuel Economy: 35 – 60 mpg (depending on engine and driving style)
• Insurance Group: Group 20 – 38 (approximate, depending on engine, trim, and power output)
• Servicing: Audi servicing can be more expensive than some rivals, but independent Audi specialists offer competitive rates. Look for models with a full service history to ensure longevity. MOT costs are standard.

Which Variant Should I Choose?

• Audi A4 35 TFSI (Petrol): Ideal for those who do a mix of town and motorway driving and prefer the refinement of a petrol engine. It offers a good balance of performance and efficiency, often ULEZ compliant.
• Audi A4 40 TDI (Diesel): A strong choice for high-mileage drivers and those who frequently undertake longer journeys, thanks to excellent fuel economy and robust torque. Modern TDI engines are generally ULEZ compliant.
• Audi A4 Avant (Estate): Perfect for families or individuals needing extra practicality and boot space without compromising on style or driving dynamics. Offers a generous cargo area and retained Audi's premium feel.
• Audi A4 S line (Trim): For drivers who desire a sportier aesthetic and a firmer, more engaging ride. S line models feature larger alloy wheels, sportier bumpers, and interior enhancements. Be aware of the potentially stiffer suspension on rough UK roads.
• Audi A4 Allroad quattro: Suited to those who need a bit more ground clearance and capability for light off-roading or tackling challenging weather conditions, while still expecting the comfort of an A4 wagon. Its quattro all-wheel drive system and rugged styling differentiate it.
