Parts for your 2009 Audi Q5-Sump plug washers

2009 Audi Q5 sump plug washers: what they do and when to replace

Yes, the 2009 Audi Q5 (8R) uses a sump plug sealing washer. Audi’s official workshop information (ElsaPro for the 8R chassis) and the Audi/VW ETKA parts catalogue specify a sealing ring for the engine oil drain plug on the 2.0 TFSI, 2.0 TDI and 3.0 TDI engines. Depending on engine and plug revision, this is either a separate aluminium crush washer (commonly a 14 x 20 mm ring, e.g. N 013 815 7) or a single-use drain plug with an integral captive seal (e.g. N 908 132 02). Either way, a sealing element is required and intended to be replaced at each oil service.

The sump plug washer’s job is simple but critical: it crushes slightly as the plug is torqued, creating a tight seal between the plug head and the sump. That seal stops weeping and drips, maintains correct oil level, and helps protect the sump thread by allowing proper clamping without over-tightening. Reusing a crushed washer can lead to slow leaks, messy undertrays and—worst case—low oil level between services.

As part of servicing your 2009 Audi Q5, the sump plug washer should be treated as a consumable. For plugs that use a separate crush washer, fit a new aluminium ring every oil change. For plugs with a captive seal, replace the whole plug. Typical torque for an M14 drain plug on these engines is around 30 Nm with a new seal, but always confirm by engine code in ElsaPro or the under-bonnet spec label. Avoid rattle-guns, use a torque wrench.

Handy tips for a tidy job under the bonnet and under the car:

• Clean the sump’s sealing face and the plug head before refitting, any grit can cause a leak path.
• Check the plug threads, if they’re burred or stretched, replace the plug.
• If the old washer is stuck to the sump, carefully remove it—don’t double up washers.
• Use the correct washer size (commonly 14 mm ID for M14 x 1.5 plugs on Q5 engines), mixing sizes can distort or not seal.

Whether the Q5 is doing the school run or a big Kiwi outback/ozzie roadie, a fresh washer at each oil change is cheap insurance against leaks and hassles on the driveway.

Do all 2009 Audi Q5 engines use a sump plug washer?

Yes. Some use a separate aluminium crush washer, others use a single-use plug with an integral seal. Both are designed to be replaced at service time.

What size sump plug washer does a 2009 Audi Q5 need?

Most 2009 Q5 engines use an M14 x 1.5 drain plug that takes a 14 x 20 mm aluminium sealing ring. Always confirm by VIN/engine code, as some plugs come with an integral seal and are replaced complete.

How often should the washer be replaced, and what torque should be used?

Replace the washer (or the complete plug if it has a captive seal) at every oil change. Torque is typically around 30 Nm for an M14 plug with a new seal, but check the exact spec for your engine code in the Audi workshop data.
