Ive been using a 33 or 30ohm 50 watt resistor and i still get the light now and again, i know when it happens so i can avoid it easily. Basically something happens when the car has reached normal operating and if let idle for a while the eml is triggered when the system has been removed.
I have read that the 330ohm 10 watt like the n112's work, but thats on mk4 golfs, so unless someone can measure the resistance at all times to check if its varying i have no idea what to use.
