Hi Sean, Yes the 4.2V is coming from the engine ECU (measured with the fan module disconnected). As you suggest the fan module must modify this in some way so the engine ECU knows its working. We still suspect the fan module but as a new fan assembly is in the region of £280 just trying to make sure. Regards Sean
