Thermostat open circuit p0597

Had the battery tested it’s down 98 amps flashing on the machine needs a recharge. So a new battery has been ordered for tomorrow. Hopefully will cure it

Did the new battery rectify the fault I now have the same fault code(s)

Thank you.

Yes I’ve had no more stop and start faults and it’s now working as it should. Fingers crossed it’s sorted.

Did the battery solve it? Have the faults come up since as it’s been a while now?

I had this fault code, ultimately resolved with replacement of the thermostat. Part number 079121115BL. Took my mechanic 4 hours of labour, and the engine light went off and did not return.

Same problem here, replaced the thermostat this morning. Never done before with this engine, 1.5 hours and it was all warmed up and well!
