Need suggestions: 3 Injectors not Working

Focus · 05-09-2014, 11:29 PM

Hi all,

So my car has had a crazy issue where it vibrates violently after a hard run one day. As of now, apparently 3 of the injectors aren't " Getting Power " or firing. I'm being told to replace the ECU as it's not supplying power to those three injectors but that just doesn't make sense to me. What would you guys reccomend I ask to have done. I dont think going big and replacing a whole ECU could be the problem as i've never read that in any thread i've searched.

Just for clarification it's cyclinders 4, 5 ,6

Who told you to replace the ECU

Is it just a misfire for those three cylinders? And other codes along with them if so?

If you turn it off then start it again does it run ok, or just get codes?

Codes associated with the misfire? Ecu replacement or fix required if you have the ecu internal failure code. Do you drive an '07 335i? Ecu failure is pretty common with msd80.

Noticed this thread last night and brought it to my shop this morning. Tested the mosfets. low and behold, cylinder 4, 5 ,6 are bad on the ECU. Ordered the mosfets and will be replacing and updating the thread once i get them
