Re: Calling all JTD drivers
I would suggest the EGR does not have the dimensions to act as a wastegate. As I understand it is there only to improve emission quality - a little. Reports on here by folks who have blanked it off before MOT is the emission levels are still OK.
So yes, cleaning was not effective and disconnecting will only leave the valve in whatever stuck position it may be in. A new one or blanking is the only cure as I see it.
