Error code p1030
 

My engine management light has recently started coming on and going into limp mode and when I attach my reader it gives me error code p1030.
the code then disappears when I stop the engine and doesn’t appear again for about 6-8 weeks .
this has happened about 5-6 times now until yesterday when it came on and wouldn’t go off.

has anyone had this error code and experience, if so is it an easy fix or do I need to take it into the garage?
