What Causes Smoke and a Burning Smell in the Audi A6L Engine Compartment?

[LeBrandon]

Audi A6L engine compartment emitting smoke with a burning smell is mainly caused by engine overheating, radiator failure, oil leakage, and clutch plate friction. Below are the detailed explanations: 1. Engine Overheating: After the car is used under high-intensity overload conditions, the engine temperature rises sharply, resulting in a large amount of white smoke accompanied by a burnt smell. In this case, the engine should be allowed to cool down to normal temperature before further use. 2. Radiator Failure: If the car's radiator malfunctions, the engine cannot dissipate heat effectively, leading to smoke emission. This situation requires professional inspection and repair of the radiator. 3. Oil Leakage: Oil leakage can also cause smoke and a burning smell in the engine due to high-temperature evaporation. A comprehensive inspection is necessary in this scenario.
