Hi mate
As you can see I didn't get any info in here.
However managed to get help on foreign forums.
Apparently that error we both have means there is a lack or plausible communication error between ecu and glow plug controller.
When you start your car cold glow plug controller work from few minutes to help engine warm up nicely and get better combustion.
Its very common problem on all generations BMW Diesels however on older ones it was very obvious fault number.
I managed to drive my previous Diesels with faulty glow plug controllers for years with no issues.
Now in my X5 I have not replaced it yet. I started parking in my garage. And when driving off I just rev a bit higher and no problems occur.
In my car problem occur only if I rev it to about 800 and hold it there as of slowly driving out of driveway. I just rev it higher and off I'm gone.
Also on N57 engine is much easier to replace it as you don't have to take off inlet manifold to do so.
It cost about £100 on ebay for a brand new Beru one which is oem replacement.
Good luck and let me know how you get on with replacing it and if it helped please.
Martin
