Basically try put a long story short lol it all happened about 4 week ago when leaving the round about I got a flashing coil light then the EML got codes read (in the picture👇🏼) after a couple of weeks the glow plug light stopped coming on and only comes on when it puts me in limp mode doing around 60mph… had a smoke test done found a leak repaired it and still have the same boost problem… I don’t have boost till I get passed 3000rpm and smokes… was told other day my egr isn’t responding either and is flat lined on the diagnostic
Can anyone help I’m based in Rotherham and don’t have much of an idea on these it’s a seat Leon mk 2 2.0cr170 BMN 2010

Turbo actuator or N75 are possibilities, you can vac test the actuator to see if the diaphragm is split.

Darkside Developments is down the road in Grimethorpe, best place to take it.
