Hi I have a 13 plate sri sensor came on for expansion tank changed sensor and warning is still on dash how do I clear it thanks.

this happened on my meriva , it was changed but had it back when still losing water it was fixed. Now after yesterday’s problem I don’t know. They or you can do a pressure test that should give the answer or eliminate it

Hi Dean, you will probably need someone with an OBD2 reader to clear out the fault code, which should then extinguish the warning light. And hopefully it should stay off. 

Regards Andy
