error message: wat
 

What exactly does this error mean? i've search the book and the web and I can't seem to find it. My ecu fires up just fine and now that the x4 is grounded to the block I have no problems but when I turn the ecu on it has a blinking red light (slow blinking) and when I go into the software it gives me a "wat" error. Anyone know?

I believe that's water temp error. Check your temp sender and connections.

make sure the sensor is plugged in with no frayed wires and whatnot.

Either your water sensor is not connected (check the temp reading on the handset, does it look normal), or its fed and giving dodgy readings(i doubt it), or your car has gone over 100 degrees celciuis, when this happens it triggers water temp error.

ok so it's water temp sensor. Cool thanks guys. I know I wired it up and everything so I'll just have to make sure it's correct. Thanks again guys.
