Oh dear limp mode !!!!!!!!!

Good afternoon peeps,,

had my glow plug light flashing for a while and management light on P2563 ??

coming home work I’d not noticed that it must have gone into limp mode as I was just trundling in traffic for about 20 mins. When I go nearer home so traffic not as heavy I put my foot down and NOTHING no umph,,, looked under bonnet and couldn’t hear any noises like leaking air,, but I did notice that my turbo had no whirring noise 😢,,, took my lad to work Saturday morning and it was all ok barring glow plug and management still coming on,,,

im going to try replacing both the vacuum pump things turbo boost egr control valve and pressure converter and see if that helps. 
then I may try Mr Muscle in the turbo and see if that can just shift any carbon,,, just need to see if there’s a pipe that can be removed to squirt it in from or if I need to remove the exhaust to gain access
