Hi guys new to the forum but need help with a bit of an old issue ref tpms missing on my recently purchased a 2014 from main dealer. After reading most of the posts on here about this I was able to find a person in Birmingham who had vcds to see if he activate my tpms on my car. He able to do most of the steps listed by certain members on here but the problem arose when he tried to activate line 1(3 extension-tire_pressure ) ,which wasn't there. The tyre pressure yellow icon appeared on the dash and on the mmi screen the writing appeared but was greyed out. The chap with the vcds said that line was missing hence he was unable to complete process. Any help in this missing line would be great.
