Parts for your 2017 Audi Q5-Sump plug washers

2017 Audi Q5 sump plug washers — are they used and what do they do?

Yes, the 2017 Audi Q5 uses a sump plug washer. Audi’s own technical documentation backs this up: the Audi ElsaWin Repair Manual for Q5 (8R and FY platforms) specifies “always replace the seal ring” when refitting the engine oil drain plug, and the Audi ETKA parts catalogue lists a sealing ring for Q5 engines (commonly a 14 x 20 mm copper/aluminium crush washer such as N 013 849 3, with drain plug variants like N 908 132 02). Some FY engines use a plug with an integrated one-time-use seal—functionally still a washer.

On a 2017 Q5, the sump plug washer’s job is simple but critical: it deforms slightly when the drain plug is tightened, creating a reliable seal between the plug and the sump. That little crush ring prevents annoying drips in the driveway and, more importantly, protects the engine from low oil caused by a slow leak. Whether it’s a separate copper/aluminium washer or an integrated seal on a replacement plug, the principle is the same—one-time crush for a leak-free seal.

As part of regular servicing, the washer should be replaced at every oil change. Audi’s workshop guidance treats the seal as single-use, because once it’s crushed, it won’t seal the same way again. On some FY models fitted with a plastic-style plug and O-ring/seal, the entire plug is a one-use item—replace the plug rather than reusing it. Always torque the plug to the specification for the specific engine variant, and never “give it a bit more for luck”—over-tightening can distort the washer or damage the sump threads.

Good practice for owners and workshops alike is to keep a few correct-size washers on hand, confirm the part by VIN if unsure (8R vs FY can differ), and inspect the sealing face on the sump for nicks before refitting. After the service, wipe the area clean and check for weeping after the first short drive. It’s a cheap part that saves headaches, and it’s absolutely worth doing right—fresh oil, new filter, new washer, and the Q5’s good to go for the next stint of kilometres.

• Replace the washer (or one-use plug) at every oil change.
• Use the correct size/spec, verify by engine code or VIN.
• Tighten to the specified torque—no over-tightening.
• Check for leaks after the first drive.

Popular questions

What size sump plug washer does a 2017 Audi Q5 use?
Most 2017 Q5 engines use an M14 drain plug with a washer around 14 mm inner diameter and 20 mm outer diameter (as shown in Audi ETKA listings such as N 013 849 3). Because there are engine and platform variations in 2017 (late 8R vs early FY), it’s best to confirm by VIN or engine code before buying.

Can the sump plug washer be reused on a 2017 Q5?
It’s not recommended. Audi’s ElsaWin repair procedures call the seal a single-use item. Crush washers lose their sealing integrity after the first tightening, and integrated-seal plugs are designed for one-time use. Replacing it each service helps avoid weeps and keeps the sump threads from being over-torqued.

What torque should the Q5 sump plug be tightened to?
Torque varies by engine and plug type. Many M14 steel plugs sit around the 30 Nm mark, while plastic one-use plugs are typically lower. Always follow the service data for the exact engine code. If in doubt, check the workshop spec rather than guessing—proper torque protects the washer and the sump.
