I have similar problem with the coolant temp light. But instead of the solid light,I am getting a flashing bule light. And one time, the tachometer went over 3000 even when the car was in idle!! Any ideas what it might be?
I brought my car back to dealership this morning. They replaced the coolant temp sensor for me. All problems fixed.Porkchop said:According to Bentley, flashing blue means electrical malfunction (cooling system related). Mine was fixed with aforementioned coolant sensor replacement.
I haven't had any tach gremlins (yet).
