Audi A1 petrol service intervals and maintenance
Audi A1 petrol engines in this family are commonly badged TFSI and can include units such as 1.0 TFSI, 1.2 TFSI, 1.4 TFSI, 1.8 TFSI and 2.0 TFSI. Follow the scheduled oil and filter changes shown for your selected engine, as clean oil is critical for turbocharged petrol units. Keep on top of spark plugs and ignition components at the specified intervals, and address any running issues early to protect the catalytic converter. If your A1 is used mainly for short trips, it is worth checking service items more frequently for signs of fuel dilution in the oil or accelerated wear.
