Ok I did a search 1st w/no luck, blah, blah, blah.... I have a new motor (complete new motor top to bottom) due to catastrophic #1 con rod failure (probable lean condition) and the new motor's running great except now I get a code 1477 w/the "Service Engine Soon" light.

My handy-dandy Bently manual says this is the code for "Leakage diagnostic pump reed switch did not open" Also lists a MINI FC of 5239.

No idea what that is or what that means.

The code seems to only come on when the car is cold (1st start of teh day) and I can clear it w/no issues w/my Peake Research tool. Car seems to run fine regardless of teh light/code but want to "fix" this to ensure it's not an indicator for more serious issues...

Any ideas?

 

Is this an R56,? What year? Is it an S. Give us more details.

 

Oof...R53. Just noticed that I posted this in the wrong forum.

Off to the correct forum!
