I have a 2015 BMW Z4 and recently noticed that it has a rough idle when starting up or when waiting at a red light. What could be causing this issue and how can I fix it?
ReplyI had the same problem with my BMW Z4 and it turned out to be a faulty spark plug. I would recommend checking your spark plugs and replacing them if necessary.
It could also be an issue with your fuel injectors. They may be clogged or damaged, causing the rough idle. Have a mechanic inspect them and clean or replace them if needed.
