BMW 328i 2013: Faulty injector

Asked by Graeme

I am having trouble with a faulty injector on my 2013 BMW 328i, and I'm being told I need to replace all four as "they work as a set". This is not cheap and I wonder if it is really necessary?

I would only replace the faulty one, unless the others are suspect in which case it’s probably best to replace all of them.
