Thermostat Code
 

Hi,

2009 R55 S 120,000 miles Got this code a while ago. Now it's a little more frequent. The radiator was low. Filled up the bottle to the top and it sucked it all down. Opened the bleeder cap to make sure no air was in it.
Do these codes absolutely mean that the thermostat needs replacing or is it something else?


Thanks,

Frank
