BMW Repair: Fuel injectors - BMW 528i, bmw 528i, spray pattern

Question
Tino,

This again about my 1996 BMW 528i, can you advise what way is there to find out if the fuel injectors are working properly & in good condition?

Thanks,

Janak.

Answer
Hello Janak,
You have to remove all of them, then the injectors are connected to a fuel pump and the spray pattern is checked, and the amount of fuel sprayed based on a give amount of time are determined. No dealer does this, and only willing injector repair shops will do it for you for a fee.
