Like everyone else I've been plagued by the 'humidity in diesel filter' message. I put the car in for a service and was told that there is a software fault. You must let the computer run through the checks before starting up. So wait a few seconds and yuou wont get those annoying beeps..maybe

That's what I've found works. Just wait until the glow light goes out at least.

I do all that, no difference, they say it's a bug.

When you start your car and you get this message quickly turn the ignition off and start it again.If the message re-appears then the humidity sensor will need to be replaced, If not unlucky its a characteristic of your car.

Believe Me its a bug. The check panel is to quick for the sensor. Stilos, have problems for oil pressure warning light on. Its Quite simple just disconnect it.
