BMW Repair Questions? Ask a Mechanic for Answers ASAP
Hello im Rob. A UK Certified Motor Technician assisting you today..
The most difficult part really is getting them pulled out from the cylinder head..some can come out with slide hammer and the special injector puller attachment and lots of penetrating oil down round the injectors to soak in..but often if they are properly siezed..you have no alternative to employ someone with a hydraulic puller...If they do come ok and easily enough and the injectors arent faulty,new ones or replacement need coded.you can replace the seals
Well you could get someone to come out to it.if they have a decent scantool..most highend Autel,Bosch diagnostics ones these days can do it..or if they have INPA which is basically near enough to dealer level...
