Last week I noticed a misfire when idling and a slight juddering changing gears which quickly got a lot worse. There were no warning lights, but I got it booked straight into a garage. They serviced it, oil change, new spark plugs etc. It has improved a lot since, but I still have a mild misfire when idling. Any ideas what this could be?

Thanks in advance!

It sounds like you have an ignition coil going out, have you run the codes to see which cylinder is having the problem?
