General Diesel fuel additive fault

[s88ahg]

Can anyone tell me if the Ulysse 04 has a fuel additive tank, as this fault code is showing when run on computer at my garage, the mechanic there was unaware this car has that if anyone can help I would be most grateful, TIA

What was the fault code?

Dont know the actual code but it said diesel fuel additive, which the mechanic knew means the fuel additive tank needs topping up but was unaware the Ulysse has one

Should be under car, below passenger seat.
