Auto Trans P1857 00 Error DTC

[Mack89]

Hi,

I’m new here and new in Audi World,few days ago I’ve search for errors with VCDS my Audi A6 C7 CVT gearbox and it comes up with error P1857 00 Error Message from Ecu after I notice a jerking/shaking while move from full stop mostly on uphill,but apart of that it works as new.As far as I search for this error it might related to MAF sensor bad reading which might can cause some intolerances to the transmission also.Mention that the gearbox was rebuild few months ago due to not go in reverse gear.I’ve attached 2 pics with VCDS outcome DTC’s

Is that should be the case or there could be something else?

 

Thanks
