Why is my Audi A1 engine losing power at high speeds?

I recently bought a used Audi A1 and I noticed that the engine seems to lose power at high speeds. What could be causing this issue and how can I fix it?

There are a few possible reasons for this issue. It could be due to a clogged air filter, a worn-out fuel pump, or a faulty oxygen sensor. I recommend taking your car to a trusted mechanic for a diagnostic test to pinpoint the exact cause of the problem.

Another potential cause could be a problem with the ignition system. This could be due to worn spark plugs, a faulty ignition coil, or a malfunctioning spark plug wire. It's important to address this issue as it could lead to further damage if left untreated.

In some cases, the issue could be related to the transmission. It's possible that the transmission fluid needs to be flushed and replaced or there could be a more serious problem with the transmission itself. I recommend bringing your car to a dealership for a thorough inspection and repair.
