Freelander 1 TD4 eml with exclamation mark appear 5 seconds when full throthle

Hi all.
New owner Freelander 1 td4 2004 automatic and have some issues.
1. Eml with exclamation mark appears 5 seconds when full throttle, cuts power (a little), dissapears after.
2. I have intake air sensor (but no wires) and on scanner, i receive error with faulty sensor (meaning that it's not connected) but as i said, i don't have wires to connect.
3. On scanner i have 2 errors. After i delete those errors, car it's working great (without eml with exclamation mark ), have good power and all ok but just for 5 miles. After this, same problems.
4. Car it's heavy on diesel with low mileage/l.
I attached pictures to see what i am talking about.

Any help it's needed.
Thanks in advance.

*Sorry for my bad english, it's not my native language!!
Cheers!

Hi,

For the temp sensor, open your eyes look next to yellow oil gauge, there is a connector just next to it. The engine works perfectly without it.

For fuel sensor, on your diag device you should have live data for the fuel presure first the low presure pump and the high presure pump. Check that first.

Can be the fuel filter, the low presure pump …

Sorry for my mistake. For the temp sensor, picture it's not mine, it's taken but looks just like mine, without wires/plug. I modified picture now. As i said, no wires/plug can be found.

Diag device it's not mine, i will go and scan again and check what you said and keep update.

Hi. Today i fitted new fuel filter (made a small service) and also scanned my car after with a basic scanner.
I have 2 picturres attached. One it's fuel rail pressure in normal throttle and 2nd it's in full throttle.
Hope it will tell you something.
Thanks.
