XC60 D5 GT MY2010: AWD off!?

Hello Today I got the following error message shortly after I started the engine and started the drive: AWD switched off, had it fixed…!? During the closing drive it was not noticeable that the AWD was switched off. Also I could not detect any noises or vibrations or anything else negative. Did one of you already get this error message displayed or maybe one of you has an idea what this has to mean exactly now? Can I without hesitation far away On Monday I will definitely drive to the workshop and have a look at it… Until then I would be very happy to hear your contributions on this… Otter
