Hi MrFeo and

to the Forum.
The non working Heated Grip may be repairable.
See this Topic :
Heated grip failedIf it's not repairable the individual Grips can be purchased for replacement
but they are now quite expensive at around US $100 each.
Part Numbers are T2042512 for the Right Hand Grip
and T2042513 for the Left Hand Grip.
Regarding the Heated Seat - ( all Heated Seats were optional additional accessories ),
it's easy to tell if it is the Heated Seat as there should be a Tag Label
visible at the rear left of the seat that says "Triumph Heated" or similar,
or if you remove the seat ( operate the keyed lock above the rear light
to release the Pillion Seat, remove that then lift the Rider Seat off ),
the wiring for the Heated Seat will be obvious.
( There should also be the Switch fitted in the left side panel ).
No wiring means it's not a Heated Seat.

Note that Heated Grips AND Seats only work when the engine is running,
and that the Instrument Panel Icons appear when they are switched ON,
then are removed from the display a few seconds after switching them off.
The TPMS Warning message is likely to be due to low voltage of the TPMS Sensor battery.
For some versions the TPMS Battery can be replaced,
though Triumph do not advertise or promote this,
and would prefer to sell a New TPMS Sensor !
Topic here :
Replace tpms batteryAs an alternative to replacing the TPMS Battery ( or the Sensor ) some Owners
have elected to disable the TPPMS system, which can either be performed by a Triumph Dealer,
or ( along with many more Maintenance related operations ) by use of the After Market
DealerTool device.Pannier Retention Straps are Part Number T2356025.
Cheers
