Thank you for the advice. Could you please elaborate on the location of the gearbox oil level indicator and the procedure for checking it? I am not very familiar with this particular process.

Certainly. Although I am not familiar with the specific layout of a Fiat Fullback, it should be straightforward. Unfortunately, I am not familiar with the details of your car. However, I strongly advise that you visit a workshop to avoid further damage to your transmission.

I appreciate your help. Following your suggestions, I visited a mechanic who confirmed the low oil level. The transmission oil pressure sensor was indeed faulty due to this. The total repair cost was 365€. Everything seems to be working correctly now.

That sounds frustrating! I had a similar experience with my old Volvo XC60, although the symptoms weren't quite identical. The gearbox issues and warning lights are definitely concerning. Have you checked your gearbox oil level? In my case, the low oil level was causing the pressure sensor to misread, triggering the limp mode. It's a simple check that might save you a trip to the mechanic.
