Can I still drive when the Audi oil warning light turns yellow?

Audi oil warning light turning yellow indicates you should not continue driving. You need to add engine oil before resuming operation. Continuing to drive with insufficient oil may cause piston knocking against cylinder walls leading to engine stall. When oil is excessively consumed, it can result in insufficient oil pressure and tension during high-speed driving, causing timing chain jumping, power deficiency, increased fuel consumption. More severely, it may lead to piston impacting valves and mechanical damage to related components. Audi is a luxury automotive brand under Audi AG, headquartered in Ingolstadt, Germany. Its main models include A1, A3, A4, A5, A6, A7, A8, Q1, Q2, Q3, Q5, Q7, Q8, TT, R8, and S/RS performance series.
