Default P0209 OBD II code

The check engine lioght keeps comming on and the code is P0209. Anyone know what this is or how I can permanently disable the check engine light? The dealer doesn't know what it is and my OBD indicates it is for thermostat temp too low and online search results say (some of them) it is an injector problem for cylinder 9, which it can't be becuae I have a 2005 LR3 4.4 V8. Any help will be appreciated!

P0128 (Coolant Temperature Below Thermostat Regulating threshold)

sounds like your thermostat is stuck open.

Thanks for the info. I did not read the code correctly because the screen on my OBD II is so small. The code is P2099. I gather this is a computer download update. Is there any reason to get this done right away or can I wait? I live a long way from the dealer.

Is there a different set of codes that apply to LR than are displayed on basic OBD II? Is that why you stated code P0128?
