Coolant Pump Control Circuit / Open P2600 any advice

[markt thomasson]

Hi Was wondering if anyone can shed some light on my issue i scanned my car i have foxwell nt310 scanner on 28th Jan came up with Fault Code P2600 Coolant Pump Control Circut Open then on 29th the engine light came up and stayed on for 2 days , called aa out they scanned it came up with same fault , could be coolant sensor or wiring then yesterday engine light went off and pending code is no longer coming up , so the question is has it fixed itself which i doubt or a matter of time until the pending code is shown again?

Ive just bought a SE W04 C220 few weeks ago and got this same thing. Random engine light on and off with this fault code. Whats the deal with this thing. The car is running absolutely fine. No problems. Is this a serious fault that just be fixed pronto or could it turn into a serious fault if not fixed ?

Might it be a failing thermostat intermittently working?
