I am about to get the egr blanked off but the man who is going to do it says he has to drill a small hole through the blanking plate so the car does not register as a fault that no gas is being re circulated. Found a very good guide on the internet for blocking off the egr with no mention of drilling a hole. Can anyone advise please. Mick

 

I map them out then blank them mate, once mapped no fault codes or if there is any P code map them out to, sorted
