:cry:Hi
I'm new to this site if someone can can point me in the right direction.
I have a 2010 X5 35d just out of extended warranty and the check engine light came on.
I toke to a local shop and the flowing codes come up :
4595H/17813
4674
4593
4596H/17814
4B99
4DSCM/19804
4CC4H/19460
4Co9M/19465
I found some postings about 4B99 referring to a short circuit on bank 2 from water liking on to the engine so I cheeked and I have the same issue. My question the problem is the wiring or the injectors and how to troubleshoot ?
Thanks in advance.

Welcome to Bimmerfest! I moved your question to our X5 forum, you'll get more help in here.

You should clear all those codes and see which ones come back, there are too many right now.

Is this a misfire or external to the engine? I've heard of moisture/condensation in the turbo air coolers being sucked into the engine and causing short term issues. I'm wagging it.

I will measure the resistance of each injector to see if i can pinpoint out the bed one . Any other suggestions how can I test injectors . The dealer wants $ 1100 for 1 injector.

Do you have any idea how our piezoelectric injectors work?

Welcome!

This issue comes up periodically and I thought there was a detailed DYI on it but after searching fairly extensively I am unable to find the thread I had in mind. Maybe it was all a dream but I thought it was from another Canadian member.

In the mean time, I am attaching a doc for the injector replacement procedure. Very high level. That being said, there are threads on injectors if you do a search here, and BavAuto.com has a fairly detailed video on replacing injectors on an N54 along with detailed steps for the procedure on page 5.

Good luck, post outcome and any DIY tips.

No I have not. I just measure the resistance but all 6 are the same . 182 / 183 k ohm. I was checking the wires to and they all look fine.
