Why is my BMW 320d producing blue smoke after I used injector cleaner?
I recently added injector cleaner to half tank of diesel in my 51-plate BMW 320d. I drove it as per normal, refuelled, and then started noticing blue smoke when at traffic lights. Performance seems ok. The longer you are stationary, the more smoke when you start off. Any thoughts?

May be coincidental with valve stem oil seals starting to fail or the turbo bearing oil seals starting to fail. Don't think it will have induced either of these failures.
