Diesel Exhaust Fluid- A Cursory Introduction.

Diesel Exhaust fluid is a non-toxic, colorless, odorless and non-flammable fluid. It comprises of 32.5% of urea and 67.5% de-ionized water. This reduces the amount of nitrogen oxide into the air by almost 90%. It therefore becomes an important functionality of land rover maintenance.

It is stored in a dedicated tank of the car, later it is injected into the exhaust system to clean exhaust gases. Land Rover started using SCR catalyst Reduction Technology from the year 2016 onwards as per the EU6 emission legislation, to reduce the level of nitrogen oxide.

It then gradually became the matter of high priority as EU Legislations, as according to them you cannot start your engine without it.

Your vehicles message center will inform you by an alert when your DEF level is low, so that you can book a refill. There are four types of messages that displays on your message center after the decreased level of DEF such as

  • First message is an advisory message that arrives at the time when DEF level is towards low level.
  • Second message comes with a warning icon that states to refill the tank.
  • Third message is a countdown message that states the remaining fluid in the car and a sum total of distance your vehicle will run.
  • The final message comes with a RED sign which pops up at that time when vehicle starts to fail. This point comes when you cars DEF level reaches zero and it can’t start further without refilling.

After observing the low DEF level you must visit a Land rover authorized garages to refill the tank. In and around Richmond we at Westlake garages very efficiently can assist you in DEF refilling.
