Still dinking around with my 04, 225 - I believe it may be in limp mode, but not sure. certainly it is way down on power, barely feel the boost at all now.

In simply looking it over I found a connector laying on the intake near the coil paks. It had become detached from the "Recirculating Valve, N249", according to my Bentley manual. so I plugged it in, but did not notice an improvement. Do I need to reset the ECU, or disconnect the battery, etc.?
