Didn't make it off the driveway

after repairing the loom section, the auto electrician put it on his fault code reader and it threw up code 00519 which is MAP sensor no signal/ no positive pressure. Now I know that all the vacuum lines are in good condition and not blocked, because they were all replaced with 3m I'D silicone lines, there can't be an air leak from the manifolds because all the gaskets were replaced and everything was torqued down to vw spec, which means the MAP sensor its self needs checking. Seeing as at sensor is in the ECU housing and soldered to the motherboard, its looking like I need to get the ECU checked and fixed!
