the coolant temp sensor is by far the most common fault.the only other thing it could be is the sensor in the coolant header tank.if you disconect the 2 pin sensor from where you top the coolant up and bridge out the 2 pins in the connector with a bit of wire.if this cures the fault you know its the coolant level sensor.if it persists and its straight from a cold start then the coolant temp sensor is the most likley cause.hope this helps.

The EPC (Electronic Pedal Control) is the "fly by wire" system that controls the throttle, it took the place of the cable that went from the gas pedal to the throttle body on VW. If this light is on and there is also a P0102, MAF (Mass Air Flow) related code stored in the vehicle's computer, the EPC may be caused indirectly from a faulty MAF. If the EPC is on and there is no other codes stored, it could be a faulty electronic throttle body or need to be re-programmed. The vehicle's computer must recognoze the throttle body so when replacing it with new or used it will need to be programmed at the dealer. Recently I replaced a MAF (a common problem on VW's) on a VW Golf and when I cleared the code the EPC went off as well.
Check the engine codes, and replace or repair the faulty sensor (most likely the MAF sensor).

definitely your temp sensor is faulty, it is an easy part to replace yourself with 20mins spare and a little basic knowledge, the sensor will be located on or near the thermostat housing and best off replacing with a new one, when you get the new one it will be obviouse which one you need to pull off your car (they will look the same) then whilst replacing disconnect your battery and this will reset any codes that it may have entered due to bad sensor. dont panic too muck bout doing damage the only thing is that your computer will be ajusting your fuel mix to compensate for what it thinks is an overheating engine. hope this helps.

The fans must come on before everything starts boiling. Is there another temp sensor besides the one you replaced? Did you replace it with a switch type rather than a thermal resistor type. The temp sensor should tell the computer to turn on the fans and the computer is supposed to turn on the fan relay and it turns on the fans. If they work with the A/C, that eliminates the computer output, the relay and the fans, and gets back to the temperature sensor.
