Does anyone know if a 63 plate doblo van have passenger airbag gone through manual and doesn't show up on dash when going through ESC mode dropping young un off tomorrow in car seat can't find anything online only says about cars appreciate any help guys!!!!!

Reading between the lines, I'm guessing you may be concerned about a rear-facing child seat.
If there is a passenger airbag, the dash should have something on it, like 'Airbag' or 'SRS'.
With the passenger door open, look at the end of the dash, the bit hidden by the door when closed. If there is a switch there, you can turn the airbag off using the ignition key.
Also check inside the glovebox, if there is a lid, as the switch may be there.
No switch, probably no airbag.

Edit: It appears that the Doblo uses the computer menu to deactivate the airbag. If the menu item is not there, passenger airbag is not there.

Thankyou very much for your reply yeah bit confusing the van and car versions must be different checked dashboard menu nothing there like you said nothing in glove box too thanks again!!!

Car probably has passenger airbag as standard. On van it will more likely be an option. As most new vans are bought by companies, cost is a major factor. If the van is generally only used by a driver, there would be no need to spend on an airbag. If the van is usually double-crewed, most companies would specify a passenger airbag, to avoid any health & safety criticisms.
