The Audi A1 Allstreet is the crossover-styled, raised derivative of the second-generation A1 Sportback GB, based on the Volkswagen Group MQB A0 platform. It features proven EA211 petrol units: the efficient 95 hp 1.0 TFSI three-cylinder and the punchy 150 hp 1.5 TFSI four-cylinder with cylinder deactivation. Both rely on a timing belt that requires replacement at 120,000 km or 6 years-a crucial interval, as belt failure leads to internal engine damage. Routine Audi A1 maintenance also includes servicing the secondary air filter on 1.5 TFSI engines.
Most examples feature the seven-speed dry-clutch S tronic transmission (DQ200). Servicing the transmission fluid every 60,000 km is sensible preventative practice to protect mechatronic shift speed and prevent parking judder. On the 1.0 TFSI, monitor the thermostat housing and coolant level during the first few weeks of ownership to prevent overheating. Despite its rugged exterior cladding and slightly elevated ground clearance, the Allstreet remains front-wheel drive without Quattro mechanicals.
