AdBlue Problems, Crystallisation and Fuel Drainage
Did you know that in 2018, the AA dealt with 23,000 AdBlue® errors? When AdBlue® is mixed with diesel, it crystallises and becomes problematic. AdBlue® mixes and turns into a milky substance which sticks to most internal car parts. Literally, minutes after being mixed, AdBlue® will start to crystallize and harden, thus 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. As the AdBlue® system is very sensitive and delicate, it requires specific expertise. It is very important to deal with any issues regarding the AdBlue problems system without delay.
Manufacturers recommend that to rectify AdBlue problems contamination, every component that has been contaminated needs to be replaced, which of course is a very expensive job. Otherwise, the entire fuel system can be at risk of damage. The very nature of AdBlue® is that it penetrates deep into the fuel system very quickly, and will not be removed by simply draining.
How AdBlue Assist Can Help You
At AdBlue® Assist, our specialist team can help with this ever-growing problem of contamination – the first step is to perform diagnostic testing to understand the extent of the problem. We then use proprietary methods and specially formulated treatments designed to remove the AdBlue® contamination, to the fullest extent. With over 125 years of combined knowledge, we can deal with any AdBlue® contamination issue at the roadside or at our national Garage Assist network of workshops, and dispose of the contaminated fuel safely.
Why Pick us?
Having dealt with over 38,000 successful contamination treatments since 2009, Auto Assist Group have deployed a nation-wide specialist fleet to solve AdBlue® contamination issues. This enables us to respond within minutes and give you peace of mind instantly, making us the best choice for your AdBlue® related problems. Unlike other types of contamination, if AdBlue® contamination is not dealt with correctly straight away, it can have lasting effects that could cause engine damage. With our specialist equipment and our extensive knowledge of AdBlue® and fuel systems, we can deal with all types of AdBlue® contamination issues no matter where they occur, and dispose of the contaminated fuel safely.
Contaminated AdBlue Problems?
If your AdBlue® tank has become contaminated, our national reach means we can have you back on the road in no time. With our dedicated team and wealth of knowledge, we will physically remove the tank at one of our national Garage Assist Networks, fully drain and remove the contamination, as well as dispose of the contamination safely..
Simply The Best In AdBlue® Fuel Drainage With Nationwide Coverage
Troubleshooting AdBlue Problems
- Reading from the temperature sensor, upstream from the SCR catalytic converter
- Reading from the NOx sensor control unit, upstream from the SCR catalytic converter
- Reading from the NOx sensor control unit, downstream from the SCR catalytic converter
- AdBlue® tank for DEF quality and quantity
- AdBlue® delivery pump and injection valve
- AdBlue® metering amount
- Visually inspection for leaks
Common Faults With AdBlue Problems
Our AdBlue® Assist engineers often come across the following, common AdBlue® faults:
- a fault code ‘’P20E8 00  – Pressure too Low’’ which normally indicates that the pump needs replacing, and this is an area we specialise in;
- the in-tank heater element burns out, which our skilled engineers can advise you further on;
- Injector and connecting tubing gets clogged up – as this system works only at high exhaust temperatures, urea solution can crystallize especially if you have frequent short journeys;
- NOx sensor can break or give a false reading especially in Mercedes NOx Errors.
- AdBlue® Check Additive See Operator’s Manual
- AdBlue® Range
- Engine Start Not Permitted (AdBlue® Empty)
- Check AdBlue® No engine Start Possible in XXX miles/km.
- Check AdBlue® Remaining starts: X
The Two Most Common AdBlue Problems Are:
- DEF fluid low level
- A fault with the SCR system
AdBlue® Assist engineers have seen these problems and more, for example with the newer Mercedes BlueTec. This model is prone to switch to limp mode, which prevents you from driving the vehicle thereon, similar to the AdBlue® problems we have encountered with Audi, BMW, Honda, Land Rover, Lexus, Mini, Skoda, Toyota, Vauxhall, Volkswagen, Volvo. AdBlue® Assist has all the experience and specialist tools to provide you with an optimum outcome, saving you both time and money.
We not only Specialists in car AdBlue® removal, but we also specialise in Van AdBlue® removal, Truck AdBlue® removal, Plant Machine AdBlue® removal, Scania AdBlue® removal, Volvo AdBlue® removal and non-road mobile machinery.
AdBlue® technology is widely employed in non-road mobile machinery that uses diesel-powered engines. When AdBlue® is mixed with diesel, it crystalises and becomes problematic, so machinery such as hedge trimmers/chainsaw generators, bulldozers, construction machinery, industrial trucks, forklifts mobile cranes, become susceptible to crystallisation due to contamination. Fortunately, we have all the expert knowledge, workshops and roadside equipped vans, all under one roof to get you up and running in the least possible time.
