I have a 2005 GL VW manual Beetle. It has about 65,000 miles on it. It's been having this problem all summer. What it does is after I turn the air conditioner on, the gas pedal acts as if it losses connection to the engine. I've replaced the cam shaft sensor, the fuel filter, and I've had it into 3 VW shops to see if the computer catches anything, it doesn't. We are at a loss of what to do. Has anyone else had this done to them, and if so how did you fix it?
