2000 VW Passat 2.8L mass air flow circuit low input, how to repair

Question

has codes; P 1425,  P1472, P1435, P1530, P1421, P1121,  P 1117, P 102 ,P1115, P1119, P1114, P1140    Do these codes mean the wiring is old / corroded and needs replaced as well as vacuum lines ??? 21/2 years ago a E Vap system component above left rear wheel was replaced . The car cannot run more perfect absolutely fine at 243,000 miles . I put new plug wires on a year ago with around 6,000-7,000 miles on current plugs . I change 10-30  full  synthetic  oil religiously at 5,000-6,000 miles. Last December had new timing belt , both timing chains and chain sending units replaced. However now the car won't pass inspection w/ check engine light on and the enclosed codes came up yesterday. Any idea on the cost from my local German car expert who is MUCH better than Dealer repair cost who I stay away from religiously who are hideous thieves . Thank you for your help in this matter !!
