Per Bentley manual, Code "P1297" is a connection problem on the pressure hose between the turbocharger and throttle valve. Bentley manual does not illustrate or reference a "pressure hose" with a direct connection between the two (2) components (turbo & throttle valve). I checked under the hood, did not removing the plastic shrouding, was unable to locate a hose with direction connection to the turbo and throttle valve. The problem is "cold start" related, starts and idles fine problem occurs when I engage the transmission and began my travels, engine misfires. Corrective action, either push the accelerator pedal to the floor or multiple ignition starts. Vehicle is a '01 Jetta, 1.8T engine. What am I looking actually looking for?
