Sounds like an EGR issue, I think the update is coincidental with the problem.
Is it just unresponsive, and slow to get to speed, or feels like a little bump in the acceleration?
hi jeebo no its like its like a few bumps at constant speed
How did you get on with the EGR blanking plate. Did you notice a difference. Wondering what the re-percussions are post install of a blanking plate. Surely the filth has to go somewhere. Do you then need to regularly remove the plate and clean the back log out?
