Engine Oil Dipstick T40178 for Audi A4 A5 A6 Petrol Diesel

An engine oil dipstick for selected Audi A4, A5 and A6 models, used where the vehicle relies on an electronic oil level system. It gives a direct manual reading of engine oil level, which is useful when you want to confirm the level properly rather than relying only on the dashboard display.

Used for routine servicing, fault finding and oil level checks, this dipstick suits both workshop use and home maintenance on compatible Audi vehicles. It can help when investigating an oil warning, checking the level after an oil change, or comparing a manual reading against the vehicle's electronic system. For anyone working on selected petrol or diesel Audi engines, it is a practical way to remove guesswork during vehicle maintenance.

Matched to OEM reference T40178, this dipstick is intended for selected 1.8 and 2.0 TFSI, 3.0 and 3.2 FSI, and 2.0, 2.7 and 3.0 TDI engines. It may also assist with checking or supporting calibration of the driver's instrument panel where applicable. The slim, straightforward format makes it easy to keep in a toolbox or garage drawer, ready for servicing jobs or repeat checks between oil changes. Checking compatibility before buying is important, especially across different engine variants, and having the correct dipstick helps keep oil checks simple and consistent.
