Any problem in boost line balance (inc. EGR) can trigger MAF fault, thats why it should be investigated by experienced garage... how you think MAF is culprit now? What symptoms/fault codes you have?

last time i had it done at garage came up with dpf kaput had it done then a few days later engine light came on again,back to garage another £65+vat for diagnostic came up with mass air flow another bill.so that is why i no longer wish to go down garage route again i had my local indie do a forced regen and engine light came on again,so thats why i am asking for any answers to mass flow and any other sensors plus where situated and will replace one by one myself.
