hello everyone i have a problem with my l322 4.4 tdv8 2012 range rover vogue. At first it give me a warning restricted performance mode then i stop the car for 10 minutes drove home with no problem. but the day after car started but in rough idle almost no power i couldnt pass my garage ramp (almost 30 degrees) then i checked the forum. i cleaned donut pipes replaced them did a smoke test no leaks but i notice something .My driver side air(left) pipe was not sucking air. right side is normal no problem. is my turbo charger dead or is something stuck in pipes ? i removed some of the pipes but didnt see anything. what should i do next

I assume it's the same as the SDV8 where one side feeds the secondary turbo and only kicks in at higher revs.

but it wont go up to 2400 rpm either

You need to find out what fault codes are occurring.
If you're checking for air being drawn in on the left side when revs are above 2400 then that is normal as the secondary turbo will only be operated when there is sufficient load as well as sufficient revs. L405 D350 SE Carpathian Grey D5 19" rims

p1247 is the fault code
