: What does P1549 code mean?

I have a 1999 Saab 9-3 and got a check engine light on my way back from the big city, but was still able to drive for almost 240 miles with no problem at regular speeds. My Saab has problems sometimes with turbo mode if I press the gas pedal too fast, that is, it surges. When the local mechanic put the car on his computer, it came up with the code P1549 and the words "Mfr Ctrl Veh Spd, Idle Ctrl, Aux Inp".

The mechanic has never seen this code before. Except for the surging going into turbo mode, the car runs fine. Can anyone tell me what might be wrong with the car and how a mechanic might fix it?

Google be your friend. I find these explanations:

" P1549 Boost pressure control. Malfunction."
" b) P1549 - boost pressure control valve. yep, that happened to me since I have an MBC+A. You may try to clean the valve."
