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.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?
thanks for diagram much appreciated.If you have a 651 engine: item 60
