I will bullet point to keep it simple
- VAGCOM plugged in showing boost valve error (N249 valve)
- Guy thinks it may be an old error and does it again and the code doesn't show
- Remap done to 305
- Notice at 4k revs the power drops off with no engine management or any other lights, as if the wheels are spinning
- I go back to garage and tell the guy this, he plugs in laptop and the error shows up again so have bought a new N249 valve to get replaced on thursday elsewhere
With what is happening, could this be the problem? Or is there something that's not obvious you guys will know about?
