AdBlue and Wheelchair Access Vehicles

AdBlue and Wheelchair Access Vehicles

AdBlue is a trademarked brand name for a liquid that is used to reduce harmful pollutants that are released through the exhaust in diesel engine vehicles. There are a fair few diesel wheelchair access vehicles on the road and to meet strict emission standards this clear non-toxic fluid was created and manufacturers installed on its vehicles. Without AdBlue, these engines would not be able to meet the stringent emissions requirements that are in place.

AdBlue is a mix of urea and deionised water which is injected into the exhaust system. During the combustion process this will breakdown harmful nitrogen oxides (NOx) into harmless nitrogen, gas and water vapour which are then released into the atmosphere through the wheelchair access vehicle's exhaust system.

It is important to make sure that you keep the AdBlue tank topped up (your wheelchair access vehicle will also tell you how many miles you have left to travel as it would with fuel in the tank). If it runs out, your vehicle will not start so it is important to keep it topped up and ensures everything is operating efficiently.

As wheelchair access vehicles have been converted with lowered floor and the like, sometimes the converters have had to re-locate the filler cap for AdBlue. So, where do you put it when it needs topping up? Hopefully the wheelchair access car you have just purchased has been fully serviced and checked over - which should include fluid checks - like we do here at Mobility Disabled. The location of the AdBlue tank depends on your wheelchair car. Some re-fill places are right next to the diesel fuel flap (such as the Peugeot Partner Tepee with their BlueHDi engines for instance), others will be under the bonnet (such as the VW Caddy) and some will be inside the wheelchair vehicle half way up the lowered floor (such as the Citroen Berlingo Multispace).

If you have a handbook for your chosen disabled car then it will tell you the location, but sometimes this location of the AdBlue refill opening has been changed due to the adaptions that have been carried out on your wheelchair car so get in touch with the converters or where you purchased the wheelchair access vehicle from.
