I just received Betley service manual for X5.
I am disappointed.
This book is copy of BMW dealer service manual and I think is not for DIY.
I hoped to find in book some experiances and advices by experts, but nothing, only how to remove and install parts.
To diagnose - book askes dealer software, but we have not.
So I think it is not for us as DIY guys.
I think it is not worth.
