I think you have the same engine as me m8, if so, your car has a Lamba Sensor and you cannot blank the EGR off without flagging a fault up on the dash...to my knowledge.....
You have to be careful on your car (EURO IV) the ECU knows when you try and blank and lights the emissions light on the dash (MOT failure) better just to clean it and replace the vacuum hose
hello
yes my eml light does show with my egr by-pass but its never failed an MOT ,why do you think that ? if your garage is that fussy it can be cleared but it will pop up after a couple of re-starts
Can you please correct and retitle your thread to include Year/Model/Body as per the forums T&C's, see the link in my signature for details, I have done it for you in your MAP/MAF thread, thank you :thumbsup
