This is usually just a MAP sensor hose inside the ECU that goes bad, or another hose leading to it from the boost pipe. This is the most common mis-diagnosed code on this car which usually leads these wonderful cars to the junkyard when it's a very inexpensive fix.

Door handles break with time (similar to the Passats)

Coolant hoses:
Triple Hoses below the injection pump leak coolant with time or with Fuel leaking from Injection pump
