    Anybody have an idea much can you expect this to cost at a mechanic, or at a dealership, if you don’t have one of your own scanners? Thanks.

  2. The only difference is that gasoline has dme module while diesels have dde module. The rest of the modules are the same.

    Reference: Diagnostic Scanners for the BMW 2012 X5d
    Your presentation is quite informative with respect to the various diagnostic scanners. My question is does the Autel MacDas DS708/DS808 and or the Foxwell Nt 510 Function on a BMW X5d (diesel)?
    I’ve read you posted comments. The Autel is pricey but, when I furthered some inquiries my virus protection was triggered. The Foxwell NT510 seems to be helpful but again, will it function on my diesel BMW X5d? Please advise.
