On my DS3 I was thinking of blanking my EGR valve thinking it might help with future issues if it starting leaking so saving the DPF but I was told by a tuner that it needs mapping out once once blanked else it'll prematurely fail the DPF.
I know that the EGR gasses help keep the combustion temp down so if the temps are higher could this be the reason why it would fail prematurely but don't the exhaust gasses go hotter to burn off the soot in the DPF.
I'm thinking the tuner might just want me to get a map so it's more money his way, what do you guys think?
