Engine overheating in any vehicle is absolutely a dangerous situation. The stone-cold truth is- an engine can overheat anytime. And from my stance, nothing is more frustrating than experiencing an engine overheating affair in stop-and-go traffic. Low coolant or contaminated coolant, thermostat issues, broken radiator fan- are some of the possible causes due to which your AUDI engine overheats in traffic. Well, in that situation, call a reputable AUDI technician straightaway and do the necessary diagnosis- so that you can prevent catastrophic engine damage.
