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?

10 May 2019I would only replace the faulty one, unless the others are suspect in which case it’s probably best to replace all of them.
