Why does my Audi A2 engine run rough in cold weather?

I have noticed that my Audi A2's engine runs rough during colder temperatures. What could be causing this and what can I do to fix it?

Cold weather can affect the performance of your engine, as it takes longer for the engine to warm up and reach optimal temperature. This can cause it to run rough. One solution is to let your car warm up for a few minutes before driving.

Another possible cause is a spark plug issue. Cold temperatures can make it harder for spark plugs to fire, leading to a rough running engine. Consider having your spark plugs checked and replaced if necessary.

It is also important to make sure your air filter is clean. A dirty air filter can restrict air flow and cause the engine to run rough. Check and replace your air filter regularly.
