keeps poping up car drives fine been to land rover they don t knows whats wrong code b0000
inlets done very annoying

You need to get the correct codes from them - B0000 doesn't appear to be used as a DTC by Land Rover. Well, I couldn't see it in the workshop manual available online.

When you say "been to Land Rover", do you mean a LR main dealer?

You'd probably be better off going to decent independent LR specialist - the main dealers aren't interested in diagnosing strange errors - too much money to be made from simple servicing of newer cars. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

If it’s the 3.0 sdv6 it could be a sticking throttle body flap,I had same a few times then going down the M1 it went into limp mode,LR assist came out & sprayed flap with throttle body cleaner & all was ok,then it went into LR for new throttle body under warranty.
Pic below of clip to remove,pull pipe off & spray flap.
