Thread: VVDI2 vs ZEDFULL what is better for VAG and BMW

Reviews:

I have both, vvdi2 by far when it comes to VAG

i have vvdi2 and autohex2 ,for the best is vvdi2. work perfect

i have vvdi2 and zed full for vag and bmw vvdi2 is best for me
zed full is good too for other marks

I have both and vvdi2 is better, ZED FULL always delay with their software and updates compared with other tools.

i agree. Vvdi2 better. also have a zedfull, in bmw is my only option (have a tcode pro but dont buy bmw modules). made a few bmw, a x5 and x6 by obd and work fine, and a mini too. in vag is not very updated, sometimes in vw brazil have a few issues, for ex: trying to make a all key lost 2015 voyage, read pin ok, and tell me wait 15 min for security, then make weird config and dashboard say key 2-6, dont acept more keys, try again, wait another 15min, and again, i want 2 key and zedfull put 6 in programming. tcode make ok in the first attempt

I have Zed-Full and to be honest it’s a bit of a disappointment. Slow bringing out anything new on the VAG front. Older A3’s and TT’s never seems to be able to read the pin when other tools do fine. Not great on newer Marelli dash especially doesn’t like the one in the VW UP. Never manages to read any CAS modules by OBD (used to ok but hasn’t successfully read a single one for months) on top of that it’s expensive to run.
I’m about to order VVDI2 (Would have updated my AVDI but not going to be forced into dealing with KAP)

So, Xhorse VVDI2 WINS! With more support in terms of BMW and VAG key programming!
