If you want to get technical, then it would be a holding penalty of -1 lap plus 45 seconds as defined in XIII 3 a. (though perhaps you should be ahead of E-team after their 30s penalty)
If you want to know where the penalty came from, it would probably be due to being in breach of NDR sporting code rules IV 2, VI 2, VII 1 + 2 and X 3. All whilst being on probation (XIII "...where the person on probation is subject to ... more strict penalties for incidents.")
