Air Mass Meter error P0101 -

HI, Ive got a RR SPORT 2009 3.6 TDV8. Recently ive been getting restricted performance error message and then goes into limp mode. now i have noticed before it happens that it seems to judder like its running out of petrol but not as extreme as that. slight forward backward jolts enough to make my belly wobble. I took it in for diagnosis and ive attached a copy of their findings. They said it might need both turbos changing at a cost of approx £4k!!!!! i have watched a video on YouTube that suggested replacing the Air Flow sensors or possibly cleaning them. Any thoughts?

Thanks in Advance.

Hi as both codes are air related start with the easy stuff; is air cleaner dirty, any air leaks any restriction in air intake Clean MAF and MAP sensors

Looking at fault codes it looks like it wants a maf sensor I would swap left to right and see if the fault code changes. as the fault code says voltage above threshold it rules out split pipe as you would have a correlation fault aswell as a maf fault
