Hi people really hoping one of more of you could take the time to help me get back on the road.

New to Range Rover........ My 2017 Evoque spat the dummy and on the way back from holiday and wouldn't start, ended needing the RAC to take the car to a local garage (not local to me) as that was all they would do at the time, I have looked all over and to get a general feel for what may be wrong with the car however I am no modern mechanic, and all the modern technology passed me by many years ago when an ECU was introduced to cars.

Fault code P2381 - 17
Fault code P0101 - 35
Fault code P0342 - 00
Fault code B1412 - 96

I find myself in a position where the garage that its presently at have no clue with regards the codes and how to fix it, My only other 2 options are another garage that say they could fix it has a 4 week waiting list, and local Range Rover garage has a 14 week waiting list........ Can anyone tell me if the car requires specialist works to rectify the issues or can parts be bought to replace those that may be causing the issues, replacing parts I can probably do, where and what they are is the issue!?

Note any of the above codes that relate to air flow according to the RAC guy was due to him removing the air flow meter to get access to the gear box lever if that helps.

Hoping someone can help as I am really in a bit of a pickle as you can see,

Cheers and any or all help appreciated.
