Reliability, common problems and owner reviews for the Audi Q5 2.0 TDI (CAGA / CGLB). Check this before you buy used.
The 2.0 TDI is the volume Q5 engine and the sensible high-mileage choice — strong, economical and well-matched to the quattro SUV. The EA189-era cars carry the usual common-rail items: DPF/EGR on short trips, injector wear, and on some early CR engines oil-pump/balance-shaft attention; later EA288 cars added AdBlue. With disciplined oil and motorway use it's a dependable long-hauler — the engine to buy in the Q5.
