AUDI A4 — What to know
The A4 is Audi's highest-volume model and has strong independent specialist support. The 2.0 TFSI engine is widely understood and parts are plentiful. That said, Audi's dealer-only coding requirements for some modules and the prevalence of DSG gearboxes mean repair costs exceed mainstream equivalents.
