Common Audi Issues (and what to do)

Oil/Coolant Leak While Driving
Typical leak points include valve covers, cam bridges, oil filter housings, and water pumps. Many appear only while driving.

Carbon Build-Up on Audi Intake Valves
TFSI engines are notorious for carbon deposits. This buildup causes:
Misfires
Hesitation
Reduced power
Poor fuel economy
Walnut blasting is the recommended method to restore airflow and engine performance. Regular cleaning ensures better throttle response and long-term reliability.

DSG / S tronic Transmission Hesitation
Delayed engagement, jerking, or shuddering often indicates overdue DSG service.

Audi Timing Chain Rattle/Check Engine
Common on 2.0T and 3.0T engines. Early diagnosis prevents catastrophic failure.

Audi Water Pump / Thermostat Failure
Many modern Audi engines use composite water pumps and electronic thermostats that are known to fail prematurely—sometimes as early as 40,000–60,000 miles.
Symptoms include:
Coolant loss
Overheating
Sweet smell from the engine bay
Coolant residue around pump housing
Addressing these failures early helps prevent overheating and cylinder head damage.

Audi PCV System Failure
Causes rough idle, boost loss, oil consumption, and vacuum leak symptoms.
