Reliability, common problems and owner reviews for the Audi A3 2.0 TDI 140hp PD (BKD / BMM). Check this before you buy used.
Strong PD 2.0. The transverse A3's PD 2.0 uses a chain-driven oil pump with NO balancer shaft, so it does NOT suffer the catastrophic oil-pump failure of the longitudinal A4/Passat (BKP). Watch the DMF, swirl flaps, DPF/EGR and (BKD) injectors.
