Why doesn't my Audi A2 start when it's cold?

I've noticed that my Audi A2 sometimes has trouble starting when it's cold outside. Why is this happening and what can I do to prevent it?

One possible cause for this issue is a weak battery. Cold weather can cause a weak battery to fail, making it difficult for your car to start. You should have your battery tested and replaced if necessary.

Another common problem with starting your car in cold weather is a faulty starter motor. If this is the case, you may need to have it replaced by a mechanic.
