A single drop of Diesel can contaminate several litres of AdBlue®. If you start up with an AdBlue® tank filled with Diesel, you risk causing very serious damage to your vehicle's SCR system. If you do start up, you vehicle will begin to behave strangely.

What happens if I accidentally put AdBlue in my diesel tank?
As AdBlue is not compatible with any engine materials it can very quickly corrode all components and pipework within the engine. If this happens the entire fuel system will need to be replaced. You must contact a professional to drain the tank immediately and dispose of all contaminated fluid.
Can a small amount of AdBlue in diesel tank?
Absolutely NONE ! Even the smallest amount such as half a litre could bring your engine to a stop. Do not delay It is essential the problem is dealt with promptly to minimise any damage. At worst the vehicle could be a write off due to the cost of parts and labour to replace the whole fuel system and the engine.
Can AdBlue damage injectors?
AdBlue contamination can cause crystallisation in your fuel system, resulting in poorly performing or outright damages. ... Therefore causing blockages and serious damage to high pressure components such as high pressure fuel pumps, injectors, fuel lines, fuel tanks, possibly causing your engine to fail completely.
Does diesel float on AdBlue?
Generally speaking, accidentally putting diesel into your AdBlue™ tank is unlikely as the AdBlue™ fill point is designed for a smaller spout nozzle (19mm), making it impossible for larger diameter diesel spouts to fit. The other way round however has become a common problem.
Does add blue crystalize?
Ad-blue will crystallise when exposed to air, any signs of crystal in either your diesel tank or a fuel sample is proof of ad blue contamination. if ad blue is mistakenly added to the tank, do not turn the key, drain the tank immediately and clean with warm water.
Can any diesel engine use AdBlue?
AdBlue is only applicable to diesel engines and is an emissions reduction technology that complements existing DPF technology. Diesel cars fitted with a DPF may not necessarily feature an AdBlue tank. However, cars with an AdBlue tank always feature a DPF as part of the overall emission control solution.
Can you overfill AdBlue tank?
Do not overfill the AdBlue reservoir. ... On some cars, the AdBlue pump and circuitry are located on top of the tank, so overfilling risks moisture contamination that can damage the circuits.
Is diesel heavier than AdBlue?
AdBlue is less dense than diesel, so will float on the surface, be picked up by the fuel pump and fed through the injectors. ... It's important to remember that AdBlue never enters the engine and is only used to treat the exhaust gases leaving it.
How does AdBlue get contaminated?
The cross-contamination is often a result of misfuelling the vehicle and even immediate draining of the tank may leave sufficient AdBlue behind to cause common symptoms. ... “If you discover AdBlue misfuelling, we'd recommend having the diesel pump and injectors checked, tested and flushed before damage occurs.”
What does AdBlue malfunction mean?
What the AdBlue warning light means. The AdBlue system has a pump that injects a small amount of the diesel exhaust fluid based on the engine's operating conditions. ... If this happens while driving, take your car to get the tank filled immediately, otherwise you won't be able to start the engine again.
What causes DEF to crystalize?
DEF crystallizes when stored for prolonged periods as the water evaporates. ... At that point, the tank should accept one full 2.5 gallon container of DEF. There is no need to continuously top off the DEF tank. Use the filler tube supplied with the case to avoid spills or splashes.
Is AdBlue corrosive to metal?
The aqueous urea solution requires an additional tank, which must be made of plastic or stainless steel, because AdBlue is corrosive to most metals.
How do I stop DEF from crystallizing?
How do you prevent "DEF creep"? Make sure all fittings that come in contact with DEF are tight and proper seals are used. Try minimizing breaking connections and wipe down any urea crystallization as soon as it forms. Water can be used to easily wash off urea that has crept onto the truck, tank or dispensing equipment.
Is AdBlue bad for paintwork?
That's important because AdBlue is highly corrosive and can damage paintwork. It needs to be washed off immediately with water if any lands on your car (or hands).
Is AdBlue made from pigs urine?
Is AdBlue® made from pigs' urine? AdBlue® is a synthetic, highly purified solution of urea and demineralized water NOT pigs urine. Whilst the chemical urea is in pigs' urine, it is found in much lower concentration alongside many other elements.
Does AdBlue stop DPF problems?
As the gases pass through the filter, the DPF will begin to get clogged with the soot that it has trapped. ... However, this system is not a replacement for a DPF, since cars with AdBlue tanks will always feature a DPF as part of the overall control of emissions.
