Yellow motor lamp?

Hello at my Volvo came the yellow control light, when I had this read out was the apparent defective the P1332, in the workshop it was said, can be the camshaft adjuster or not, which was looked at, but seems to be good, the message was deleted and after a few days came back the control light…. someone already had the experience, someone knows about it by chance! would like to know it without having to drive straight to the Volvo dealer g Rice
