Can I enable Indirect (ABS wheel sensor based) TPMS on 2012 Yeti SE?

Hi All,I haven't posted for a while, Wifey's Tdi Yeti still trouble free until last week. Had 2 new tyres fitted on front, 3 weeks later she gets a nail in one. It would have been an easy puncture repair, but she drove it (miles?) until after parking somebody told her the offside front tyre was flat. She got no TPMS dash warning and said she couldn't feel anything odd in steering (?) although as soon as I arrived to put on the spare I could see the body canted at an angle. The new tyre was trashed and unrepairable.

I checked the driver manual for TPMS and despite a procedure, there's no reset switch in the switch panel. Sad because I have a 2007 V.W with TPMS. I've been through VCDS long coding for Gateway, ABS, and instruments modules, Settings in MFD now show tyre pressures but basic ABS indirect doesn't use pressure sensors. A dash symbol for TPMS does now show up. So what's up? Does the coding procedure here and in other places only refer to a Yeti active sensor system? Can I still get the basic ABS system to work? Do I need the TPMS hardware loom cable and switch to get it active? From old drawings of kits it just looks like a switch on a pair of wires.

When I scan the system I now see new module 4C in the Gateway list, but it's empty of data or not communicating when scanned. Is this a real control module hardware addition for active sensor TPMS?

Any help appreciated, particularly if you have a 2012 Yeti with the TPMS reset panel switch. Does your MFD Settings say anything about indirect TPMS or offer a second means of reset?

In the process of coding I accidentally hit ABS basic Settings 'start test' and got into ABS fault error 0486 loop that was really hard to get out of.
