Having problems with your 2002 Volkswagen Golf ?

Glow plugs come on only after the engine starts. on power when light in dash is on.WTF? what could cause this? the plugs stay powered as long as the engine is running???? they should only be on for a short time before to make cold starts easier! What should I check and replace? The glow plugs are new and the relay clics so I think it's working. Could the relay be in wrong? I think it only goes in one way? Please help!

Had this before and i have always ended up rewiring the control unit feed ,i tried every which way to find the fault and then i gave up blaming the fancy computer controlled software .I just ran a feed to the unit from the ignition switch to turn it on when ignition is turned on in extreme cases i have fitted a push button type switch on the dash ignition controlled that operates the relay for the glow plugs direct .
