EPC light came on and lost all power a week ago, having strange problem now. Help please!
about 1 week ago while I was driving on the freeway my EPC light came on and I had to pull onto the shoulder as I lost all acceleration. After restarting the car I got off the freeway ok (did notice a loud blowing sound though) and got to a gas station, then I disconnected and reconnected the negative battery terminal to reset the system. Since then it hasn't happened again and my car appears to be running completely fine except for one thing: when I give it a lot of gas and really try to accelerate quickly I hear that same loud blowing or sucking noise coming from the engine. I'm assuming this has to do with the turbo since it only happens if I give it a lot of gas, but I'm only guessing here. VW guy claims he has no idea what the problem is until he looks at it for $85 an hour, anyone have a good idea what the problem might be?
