Parts for the Audi A4 TDI

Known issues

• Timing Chain Tensioner (TFSI engines): A well-documented issue, especially in earlier models. Listen for a rattling sound on cold starts. Newer tensioner designs offer improved reliability.
• Oil Consumption (TFSI engines): The 2.0L TFSI engine (particularly pre-facelift) can suffer from excessive oil consumption. Regular monitoring is essential.
• DSG/Multitronic Transmission Issues: The dual-clutch DSG and CVT Multitronic transmissions require regular fluid changes to avoid problems.
• Coolant Leaks: Check for leaks around the water pump, thermostat housing, and radiator. Pink crusty residue is a tell-tale sign.
• Carbon Buildup (TFSI engines): Direct injection engines are prone to carbon buildup on the intake valves, reducing performance.

WOF tips

• Suspension Wear: Ball joints, control arm bushings, and shock absorbers are common wear items. Listen for clunking noises or uneven tyre wear.
• Brake Condition: Rotor thickness and pad wear are critical WOF checks. Ensure the ABS system is functioning correctly.
• Lighting Functionality: All lights must be in working order, including headlights, tail lights, brake lights, and indicators. Check for moisture inside light housings.
• Tyre Condition and Alignment: Ensure tyres meet minimum tread depth requirements and that the wheel alignment is correct.
• Exhaust System: Check for leaks, corrosion, and secure mounting of the exhaust system.
