Why does my Audi A6 engine start abruptly during cold weather?

Every time I start my Audi A6 in cold weather, the engine seems to start abruptly and some irregular noises can be heard. Is this normal behavior for an Audi A6 engine during cold weather or should I be concerned?

This is a common issue in Audi A6 engines during cold weather. It is caused by the engine's oil being thicker when cold, which puts extra strain on the starter motor. To avoid this, it is recommended to use a synthetic oil with a lower viscosity rating during colder months.
