Initial publication

Although the correct amount of oil was added to the engine during an oil change service, a check of the oil level
shows that the oil level is not okay.

Technical Background
When an unapproved aftermarket speed-filling device is used to add oil to a W12 engine, the increased oil flow
rate forces oil into the intake manifold or combustion chamber and damages the engine.
For a detailed view of the W12 engine, see the image below (Figure 1).

Technical Service Bulletin
Service
1. Verify whether or not oil has entered either the intake manifold or the combustion chamber.
2. If oil is found in any of these areas, remove the oil.
3. Fill the engine with the correct amount of oil as listed in the vehicle’s Fluid Capacity Table in Elsa. (See Repair
Manual >> Maintenance >>Maintenance Procedures >>Engine Oil, Draining/Extracting and Removing and
Installing Filter >> 6.3L TFSI Gasoline Engine for more information). When filling the engine with oil, use
overhead oil dispensers, quart containers of oil, or oil-filling containers that do not completely seal the filler cap
receptacle on the oil separator or valve cover.
4. Allow the oil to drain into the oil pan.
5. Check that the oil level is correct before starting the engine.

Warning:
Do not use aftermarket speed-filling devices and funnels that have an airtight seal at the filter cap, as they are
not approved. Damages caused by speed-filling devices and funnels that have an airtight seal at the cap are not
warrantable and will not be reimbursed.

Warranty
This TSB is informational only and not applicable to any Audi warranty.

Additional Information
All parts and service references provided in this TSB (2035581) are subject to change and/or removal. Always
