Googling it throws it up as P0125 - insufficient coolant temperature for closed loop fuel control. Maybe a faulty coolant temperature sensor? Does the temperature gauge on the dash show ok, or does it seem a bit low?

Rjt87

No not really gauge shows above first middle mark, dash command also shows temperature ok but don't think dashcommands all that precise to be honest.

The code did stay off for nearly a week, so intermittent? Also originally it showed two codes, the other was P00DB but that hasn't returned.

Ok I've found this googling anyone shed any light on what the hell this could mean? P00D7

Looked at temp reading during drive to work all seems fine. Got up to temp quickly and stayed at a very steady 85c. Parked up left it running 5 mins fans kick in and out fine. Totally confused. Car seems a bit jerky when cold tho, sometimes doesn't feel quite as quick as it should be when warm. Thanks for your time tho bud

Ahh, sorry fella I misread D7 as 7D! Hence the coolant line

Not a clue with the bypass valve, sorry.
