have this car in for ecu read ,it has bad starting fault but only once a month , theres a few codes stored but im sure maf is there because it took so long to start
codes were

after clearing code only the p0435 temp sensor will not clear
the over boost is the turbo flap needs freeing off as usual
l was just going to remove dpf and delete temp sensors

my question is do you think p0435 might be starting fault ?

afew months back car came in for anti roll bar link , we put car on ramp replaced and went to pull off car started but didnt revv and was smoking after 2 minutes it slowly started to revv like its was fuel problem or exhaust blocked
we phoned customer and he said he was having this problems for over a year but it only happened once a month ?
checked maf and all readings in live data were spot on , on google if these dont start they bring these codes on sometimes
but code cleared but not temp sensor ,

try to turn off dpf filter and upload the file in the car. If it works ok, it's dpf problem. But if not, check fuel pressure sensors, injectors, disconnect MAF sensor and try without it. What about egr? is it ok?
