BBZ Fabia Having a Meltdown

Hi folks,

I keep getting these codes on my 03 1.4 16v BBZ powered Mk1 Fabia. I keep thinking along the lines of the MAP sensor but not 100%. Both myself and the recovery service I had to call out cannot find am issue with the pipework which I know is a common issue with these.

When it fails the car goes into limp mode, with EPC, ASR, and the engine lights all lit. Further it also occasionally loses all power resulting in it kangarooing if the throttle is pressed.

Any advice is appreciated, thanks!
