Why does my Audi A2's engine stutter when going uphill?

I've noticed that when driving on an incline or uphill, my Audi A2's engine seems to stutter and lose power. What could be causing this issue and how can I fix it?

This issue could be caused by a clogged fuel filter or a faulty ignition coil. I suggest bringing your car to a trusted mechanic for a diagnostic test to determine the exact cause.

Check your spark plugs and wires for any signs of wear or damage. If they are old or worn out, they may be causing the engine stuttering.

Another possibility could be a problem with your oxygen sensor. It's a good idea to have it checked and replaced if necessary.
