Parts for your 2016 Audi Q5-Sump plug washers

2016 Audi Q5 Sump Plug Washers

Based on Audi’s own technical literature, the 2016 Audi Q5 does use a sump plug sealing washer. The Audi ElsaPro (ElsaWin) workshop manual for the 8R-series Q5 specifies replacing the drain plug’s sealing washer at each oil change, and the ETKA parts catalogue lists an M14 x 1.5 drain plug with either a separate aluminium/copper crush washer or a plug with a captive bonded seal across the 2.0 TFSI, 3.0 TFSI and 3.0 TDI engines. That means the sump-plug-washer is relevant and is a standard service item on this model.

On the 2016 Q5, the sump plug washer’s purpose is simple but critical: it provides a one-time, deformable seal between the sump and the drain plug. When tightened, a soft metal crush washer (usually aluminium or copper) flattens slightly to take up tiny imperfections in the mating faces, preventing weeps and drips as the engine heats and cools. Some Q5 variants use a drain plug with an integrated, captive sealing ring, functionally it’s the same idea—single-use sealing to keep the oil in and the driveway clean.

As part of routine servicing, the washer should be replaced at every oil change. Reusing a crush washer or captive-seal plug risks slow leaks, oily undertrays, and that tell-tale hot-oil smell after a run. If the vehicle is fitted with a plug that has a bonded seal, replace the entire plug each time. With a separate washer, fit a new OEM-spec ring sized for the M14 x 1.5 plug. Typical VAG torque for these drain plugs is around 30 Nm, but it’s smart practice to follow the exact spec shown in the engine’s service data.

Good workshop habits help here:

• Clean the sump mating face and plug threads before refitting.
• Always use a new washer or a new captive-seal plug—they’re designed for one use.
• Hand-start the plug to avoid cross-threading, then torque to spec.

Drivers who notice fresh oil spots under the front of the Q5, dampness around the drain plug, or a low oil level between services should have the plug and washer checked promptly. A proper seal costs a few dollars and can prevent bigger hassles, from oil-stained driveways to underbody mess and potential engine oil loss on long trips around Aus or NZ.

Popular questions

Does the 2016 Audi Q5 use a sump plug washer?
Yes. Factory service information (Audi ElsaPro) and the ETKA parts catalogue show the Q5 uses either a separate crush washer with the M14 x 1.5 drain plug or a plug that has a captive bonded seal. Both are single-use sealing solutions.

What size sump plug washer does a 2016 Audi Q5 take?
Most 2016 Q5 engines use an M14 x 1.5 drain plug with a matching aluminium or copper sealing ring sized for that plug. Exact dimensions can vary by engine code, so matching to the VIN or using the OEM part number from ETKA is the safest bet.

Can the sump plug washer be reused on a 2016 Q5?
No. Crush washers and captive-seal drain plugs are designed for one-time use. Reusing them can lead to weeping or leaks. Fit a new washer—or a new captive-seal plug—at every oil change and torque the plug to the specified value.
