Yeah I was the same, mine started overheating on my way home from work so I had to keep stopping to let it cool down a bit.
I managed to get it into the garage the next day and it was fixed quick.
It wasn't expensive, not sure on exact price because i got him serviced at the same time

Hope you get sorted x
