Hi all,

After a previous post about intermittent lack of power, and having replaced the EGR valve with a brand new one, another fault or previous one now getting worse.
In gears 4-6 if the revs are below 1500 rpm there is a pronounced juddering from the engine at any throttle input until about 1800 rpm but it’s more pronounced in 5th and 6th. I’ve physically checked the turbo and it’s free with no excess play, the vacuum pipes are all whole as far as I can tell, the swirl flap actuator is free

I have had my car since 2016 and plan on keeping it until it dies really.

I have only really recently started doing some mods to it but have always serviced it myself.
