I have a smart fortwo, the problem i am having is that the engine temperature is going through the roof on the gauge. it has happened 3 times in 3 months. the first time, the dash started flashing and beeping and the temp was at it's highest with all blobs filled. I left it for an hour and came back and everything was fine.
The same thing happened last month, the temperature rose so that there was one black dot that wasn't black and then went down to only 40(2 black dots).
On Saturday, the same thing happened, 4 black dots and the fans inside the car went cold even when it was originally hot. On this occassion i left it, and then came back and everything was ok again.
On all three occassions, the car has been subject to rain. On saturday though, it was a jet wash.
I took it to smart today, and they say i have to have the engine head removed and engine inspected(a couple of hundred pounds before anything is replaced)
I have a remap from jonboy. Smart reckon it has something to do with that. i believe that it is an electrical fault.
Could someone help me with this please, as i dont know what to do.
