Cold start problems in Audi A4 Diesel

Hello everyone, I have a 2021 Audi A4 with a diesel engine and 120,000 km. I've noticed that the engine takes a while to start when the vehicle is on an incline or has been parked for more than a day, although it doesn't show any faults afterwards. Has anyone experienced something similar or have any idea what could be causing this problem?

(Translated from Spanish)

An Audi A4 diesel engine is experiencing delayed starts when parked on an incline or left unused for over a day, without showing any subsequent faults. A potential cause could be air leaks in the fuel system, particularly around the fuel lines and connections. Checking and addressing these leaks might resolve the starting issue.

Check the fuel system for any air leaks, especially around the fuel lines and connections. Air in the fuel system can cause starting issues, particularly when parked on an incline. Let me know if this helps or if you have any further questions!
