Sean announced the BBC’s decision in an emotional address to listeners on his Friday morning show, which aired on both Radio Foyle and Radio Ulster from 10 30 am until midday.
He told them that it would be his final show and won’t be back.
Coyle was known for many years for his double act with legendary presenter Gerry Anderson who sadly died five years ago this month after a battle with cancer.
He said that he brought the news of his departure “with a heavy heart”.
“This is my last programme, on Monday of this week I met with bosses in the BBC and they told me their plans for the future.
“There’s a whole new plan for the future on Radio Ulster and Radio Foyle and they’re making changes and I didn’t figure in the changes. I wasn’t there.
“They told me that this show would end in six weeks time and in fairness they offered me other work.
“They are bringing on another programme, what it is I don’t know. Whoever it is I wish that person every success.”
The veteran broadcaster thanked his crew and listeners for their support over the years.
“I have enjoyed it, I don’t want to go, but the decision has been made and I must abide by it,” he said.
“Was it Arnold Schwarzenegger said ‘I will be back’, you don’t know. I abide by the decision, I don’t understand it, but that’s that.
“This is my last show, I’ll not be here on Monday, I’ll not be here on Tuesday and I’ll not be here ever again, as far as I know.”
Director of BBC Northern Ireland Peter Johnston said the decision was “difficult” and had not been taken lightly.
“Sean has been a regular fixture with listeners on BBC Radio Ulster/Foyle for decades,” he said in a statement.
“He is a brilliant broadcaster and his easy-going repartee and deep musical repertoire – not to mention his countless impressions – have made him a popular voice on our airwaves.
“Whether as a presenter of his own programmes or as Gerry Anderson’s right-hand man, he has played an unforgettable part in BBC Radio Ulster/Foyle’s story.
“On behalf of myself and everyone at BBC Northern Ireland I’d like to thank Sean for everything he has brought to the station.”
The BBC has yet to announce a replacement for his 90 minute slot.
