BMW X5 Bio Diesel fuel injection system fault, please HELP?
Hi
I have a BMW X5 e53 3.0D on from the year 2003.
I have just encountered a problem today. I will tell what has happened, and hopefully someone can HELP?
I used biodiesel for the first time yesterday by a mix of about 50/50 regular diesel to bio diesel, (I know I probably should have used more diesel now). A day later the car went into limp mode on a bank and slowly got to the top, the problem then went and the car drove as normal.
A day later than that I drove the car for about 10 miles and on the same bank (coincidence?) the car went back into limp mode and eventually lost all power and came to a stop, with a note on the onboard computer saying 'fuel inject problem'.
The car now starts sometimes or doesn't even start. I have used some diesel injector cleaner (Redex) to no success.
I am waiting for a new fuel filter to arrive which will be changed.
Has anyone ever had the same problem?
Does anyone know a possible fix for this?
I greatly appreciate all help from everyone, big or small so thanks in advance.

Most likely what's happened is you bought biodiesel that wasn't properly processed and filtered. My daughter's ex-boyfriend used to use biodiesel exclusively in his GMC pickup and never had a problem with the fuel system.

Thanks for answer rivermikerat.
My dad has been using the same in his BMW 320D, that's why I thought it would have been ok. How did your daughters ex boyfriend fix the problem?
Thanks again

He never had a problem. It ran wonderfully. The only problem was that the french fry smell would make us hungry. :)
Try checking the fuel pressure. Make sure you hear the injectors pulsing during startup.
