My Touareg back in VW Service again and still carrying warranty so I don’t know what DEF module does do? It been since month now. Is something relate to computer control of AdBlue?
My computer on dashboard kept alert that AdBlue is low (100 miles left until engine turn off) but I checked my AdBlue tank level is full. Do you think DEF module need replace?
I just want know what’s does do with it?
