  1. will this NT644 perform hydraulic pressure release and hydraulic flush and bleed for BMW and Audi vehicles.

  2. Will the Foxwell NT644 do a DPF regeneration on a 2012 Peugeot 308 1.6 HDI?
    Will it reset the FAP triangle light on dashboard?
    Any other scanner do these fixes?

  3. I’m looking at this or the NT680 Pro. I always see “light duty trucks” mentioned but what about trucks like a Chevy/ GMC 2500HD with a diesel engine? How compatible are these with that type of vehicle?

  4. I have a NT644
    I have a Mercedes Vito 2016
    Is there an update for this model as I can only get vito 2008>. This is the older model

    Kind regards

  5. Hi , before doing an update I was able to Auto detect the VIN number , but after doing an update on my NT644 pro I was NOT able to Auto detect it , I just don’t know why they disabled this feature, emailed Foxwell and was told the unit is old ,, Really!! I thought updates make things better Not worse now I have to Manually enter the VIN #

  6. Will this scanner reset the clutch statistics on an Aston Martin vantage magneti marelli ASM (after clutch replacement). I have the NT530 and it doesn’t have that facility.

  7. Bi-directional control, component tests or actuation is a very important function of a diagnostic tool. I don’t see that mentioned in this review. Why not or did I overlook it? I have an NT630 which does perform tbi-directional tests but am buying a scanner which works on more than 5 manufacturers, the NT644 is one I considered but without all the info I won’t buy it.

  8. Would you please tell us about the IMMO function? Does it reset the old key and reprogram the new key for Mercedes. Do you have the owner manual so I can read before buy them. Thanks
