Can someone help me trouble shoot P0001 and misfire codes
I have a 2010 Cooper S and my OBD reader returns p0001 p0300 p0303 p0304 and p0301. I have just replaced the sparkplugs. The check engine light goes on and off. Any idea on how to chase these codes down? I am guessing that the engine misfires could be caused by the p0001 -> "fuel volume regulator control circuit open". I did disconnect the battery when I changed the thermostat housing because I found it easier to get PCM wires out of the way. Help would be appreciated. Thanks.

Sounds like you may have a failing HPFP, have you checked fuel pressure numbers?
If MINI of Canada is under the same warranty as MINI USA:
You can call the dealer to see if your car is covered under the HPFP warranty, if so you'll get it replaced free of charge.
