Sudden loss of power and white smoke when driving on the highway

Hello everyone, I drive an Audi A6 and recently had a serious problem while driving on the highway at 140-150 km/h. Suddenly there was a lot of white smoke coming out of the exhaust, followed by a complete loss of power. Since then the engine won't start properly. It starts briefly, jerks and then immediately stalls again. The speedometer display only shows the battery symbol as an error message. Does anyone have any idea what the problem could be? I would be very grateful for any help. Best regards.

(Translated from German)

An Audi A6 experienced a sudden loss of power and emitted white smoke while driving on the highway, followed by starting issues and a battery symbol error. The white smoke suggests coolant entering the combustion chamber, likely due to a blown head gasket. Checking the coolant level and oil for contamination is advised, and a mechanic should inspect the vehicle promptly to prevent further engine damage.

White smoke from the exhaust often indicates coolant entering the combustion chamber, which could be due to a blown head gasket. The loss of power and starting issues further suggest this might be the case. Check the coolant level and look for any signs of oil contamination (milky appearance) in the oil. If you find any of these signs, it's crucial to have a mechanic inspect the vehicle as soon as possible, as driving with a blown head gasket can cause severe engine damage. Let me know how it goes or if you have any other questions.
