Launch programed additive tank to car? Hmm.

[@paulsteane897]

Only PSA software can do that..

[@mrtommyP80]

​@paulsteane897 any one know how to decode tpms out the car ?

[@maxautouk]

@@paulsteane897 almost any decent scan tool can program a replacement tank or fluid or DPF or do relearns… nothing unusual there
We have Lexia at our garage which is the main dealer software which can do it - we also have some autel stuff which can also do it 👍🏽 hope that helps
