By taking it to a different garage who don’t know about the malfunction it would be a pass?.
They can't fail your van if it's illuminated, flashing, the fact they know it has a fault or the light is busy attacking passers by.
This is all assuming your van is not a caravelle as it will be registered as a car (M1) and is a van (N1)
As quoted from the MOT testing guide,
The inspection of the tyre pressure monitoring system (TPMS) is for M1 vehicles first used on or after 1 January 2012.
