Is your ticking sound electrical sound like an electric shock?
Also i don't think it is the lifters as that issues does not seem to be on the 335i cars.
Love to hear what others say.
I am surprised dealer told you to get them cleaned, why didn't they offer to clean them and charge ridiculous price for it.
Can anyone recommend a good injector cleaner DIY or product for the N54?
