I have a 2005 A4 Quatro Cabrolet. Recently, I noticed smoke in the engine compartment which seems to be coming from the lower left side of the engine compartment. The smoking starts very quickly when I start the car from cold, but as it warms up the smoke goes away. The smoke smells like plastic burning. I have no clue what this can be. Does anyone have any experience with this type of problem ?
