Acceleration and power problems on Audi Q5

Hello everyone, I have a problem with my Audi Q5. When I start my car after a long period of inactivity (a few hours), I have the impression that something is slipping in the engine. This happens for the first 600/700 meters, then there seems to be no problem. What's more, I've noticed a loss of engine power and jerky acceleration. Has anyone ever encountered this kind of problem and could help me solve it? Thank you in advance for your help.

Summary of the thread

The Audi Q5 is experiencing a slipping sensation in the engine and a loss of power after long periods of inactivity. This could be due to low or degraded transmission fluid, worn engine mounts, faulty spark plugs or ignition coils, or issues with the air intake system. The suggested solutions include checking the transmission fluid level and condition, inspecting the engine mounts, spark plugs, and ignition coils for wear or damage, and examining the air intake system for leaks or blockages.

Check the transmission fluid level and condition first, as low or degraded fluid can cause slipping and jerky acceleration. Make sure the car is on a level surface and the engine is warm when checking. Let me know if this resolves the issue or if you need further assistance.

The car has just been serviced, the gearbox changed and the belt replaced (215900 km).

I also had to change the exhaust manifold twice, which broke 2x in 5 months.

Inspect the engine mounts for wear or damage, as faulty mounts can cause vibrations and a slipping sensation. If the mounts are fine, consider checking the spark plugs and ignition coils for any signs of wear or damage, as these can affect engine performance. Let me know how it goes or if you have more questions.

Check the air intake system for any leaks or blockages, as these can affect engine performance and cause jerky acceleration. Ensure all hoses and connections are secure. Let me know if this helps or if you need further guidance.
