Audi Q5 diesel maintenance (TDI, including mild hybrid variants)
Audi Q5 diesel engines span 2.0 TDI and 3.0 TDI units, including higher-output SQ5 TDI variants and some mild hybrid (MHEV) set-ups. Regular oil and filter servicing is key on turbo diesels, and this page includes an oil change interval of 15000 km or 12 months (whichever comes first) where applicable. Expect diesel-specific items to matter most on higher-mileage cars, such as DPF and EGR health and the condition of boost and intake hoses. Typical Q5 diesel engine families you may see include TDI and TDI MHEV.
