Can you overfill AdBlue tank Mercedes?

Fixing the problem – After accessing the vehicle serial data, we found the following fault code: P140300 – The control unit AdBlue has a malfunction Armed with the serial data, our Mercedes Galway specialist technicians accessed the AdBlue pump and started to check the system’s wiring.

They found that there was no power going into the AdBlue module, so they began stripping back the wiring to locate the defect. Upon further inspection, it was discovered that the main loom had completely rubbed through, resulting in water contamination and some serious corrosion to the power wires. In this case, we were able to perform the wiring replacement and re-insulation onsite at Donnellan Auto Services.

As the technicians were working on the AdBlue system, they also noticed a problem with the level sensor. The client had already told us that he had overfilled the system, which shouldn’t happen when working with an ultrasonic sensor system. Fortunately, our knowledge and experience have taught us that if you overfill the AdBlue system, the ultrasonic sensor is unable to detect the level and thus misleads the vehicle’s electronics.

After draining the AdBlue tank system, we refilled the tank to the correct level. Once the Mercedes C220’s AdBlue level was correct, we took it for a test drive to confirm that the Engine Management Warning light had disappeared and it was back to being reliable and road safe. In less than 24 hours, the client was able to get his car back.

The first-time fix he received from Fergies saved him from the stress and money of repeated repairs. We explained everything to Mr K in detail so that he understood what was going on and that there wouldn’t be any unnecessary costs.

How much AdBlue do I add?

The dos and don’ts of using AdBlue AdBlue: if you are driving one of the latest clean emission Euro6 diesel cars, no doubt you’ve already topped up the special tank on your new car with the additive. But what is this new substance if you haven’t come across it before, why is it important to the well-being of your vehicle and how often should you have to add it to keep it in tip-top condition? Here we explain in detail the do’s and don’ts of using AdBlue.

  • New Euro6 emissions regulations for diesel cars came into effect from September 2015 (a year later for vans) and were introduced to target a host of harmful gases linked to respiratory disease.
  • The new rules especially focus on nitrogen oxides (NOx) and cut the permissible limits for NOx from 180mg/km to just 80mg/km.

The aim is to reduce these harmful emissions, thereby limiting the impact on the environment and public health. Many major European cities, including London and Paris, are currently looking at banning diesels at certain times and on certain days that don’t meet the Euro6 regulations.

To meet the new targets, vehicle manufacturers have largely turned to a process known as Selective Catalytic Reduction which involves the injection of a Diesel Exhaust Fluid (DEF) into existing gas circulatory systems and which assists in the breakdown of harmful NOx, This DEF is commonly known as AdBlue,

Clean Air Zones, such as London’s Ultra Low Emission Zone, require diesel cars and vans to be Euro6, otherwise a daily charge is required to enter the zone. What is AdBlue? AdBlue is actually a synthetic urea which works by turning nitrogen oxide into harmless steam and nitrogen.

  1. It is stored in a tank, like fuel, and an increasing number of diesel vehicles, but typically those with larger engines, are being fitted with AdBlue tanks.
  2. However, certain manufacturers may refer to it simply as ‘Emissions Additive’.
  3. AdBlue is not injected into the engine as a fuel additive.
  4. It is added to the catalyst system in the car’s exhaust system.

AdBlue is consumed in proportion to engine usage. It is estimated that a passenger car will consume approximately 1.5 litres of AdBlue for every 620 miles. The size of AdBlue tanks vary, too, so when you need to top up depends on your driving style, the number of miles you cover, and the size of the tank.

A dashboard warning light will let you know when it is time to top up. Use of AdBlue has been common on trucks and buses since 2006 following the introduction of Euro4 regulations for those vehicle classes. Whose responsibility is it to top-up with AdBlue? AdBlue is considered a consumable similar to fuel.

Therefore it is the driver’s responsibility to ensure the AdBlue tank is kept topped up and to pay any costs associated with doing so. AdBlue must never be added to fuel. AdBlue is always stored in a completely separate tank. However, in many vehicles the AdBlue filler will be located next to the fuel filler.

  • It should also be noted that any damage incurred through the misuse of AdBlue such as adding it to either petrol or diesel tanks, or a breakdown resulting from low AdBlue levels, will not be covered under maintenance or recovery arrangements.
  • Maintained leasing contracts do not cover AdBlue costs.
  • However certain lease providers will top up AdBlue as part of a routine service.

Drivers should make themselves aware of their responsibilities by consulting their vehicle handbook. How is it used?

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.AdBlue and DPF warning lights are separate and will illuminate independently of each other.

How much AdBlue will my vehicle use?

AdBlue is added to fuel appropriate to consumption. Usage is therefore affected by driving style, journey type, engine and vehicle load, and environmental conditions.AdBlue can be purchased from automotive retailers, garages, dealerships, some fuel stations or online. As a general guide, Halfords sells a 10 litre container of AdBlue for around £12.50.AdBlue filler location varies between manufacturer and model. Typical locations include the boot, next to the fuel filler, or under the bonnet.The size of the AdBlue tank fitted to vehicles varies between manufacturers and models, so therefore the interval between top-ups will vary.Based on conservative estimates, AdBlue may require topping up every 5,000 to 8,000 miles although this will fluctuate based on manufacturer, model, and driving style.

How do I top up AdBlue?

Some manufacturers may provide AdBlue free of charge in certain circumstances such as part of a routine service. But it is highly unlikely that refills during routine serving alone will maintain AdBlue levels sufficiently.Cars with variable servicing require particular attention as they are virtually guaranteed to require an AdBlue top up before the initial service.When AdBlue is running low, a series of warnings will be given via the driver information system. As an example, Audi models display a countdown from 1,500 miles before a required refill.It is vital these warnings are acted upon promptly. If AdBlue falls below a pre-determined level, the car will continue on reduced power. Once it is stopped it will not restart until sufficient AdBlue is added. Should this occur at the side of the road, you will be charged for recovery.Taking Audi as an example, a minimum of 5.7 litres of AdBlue is required to restart the vehicle, although this level varies between manufacturers. AdBlue must never be added to fuel. If AdBlue is added via the fuel filler, you should not start the vehicle and immediately call the appropriate emergency support number. If you accidentally add fuel to the AdBlue tank, the same applies: do not start the vehicle and immediately call the appropriate emergency support number.

Is 10 Litres of AdBlue enough?

How Much AdBlue Do You Need? – You need between 10 and 11.5 litres to fill an AdBlue tank, on average. Larger vehicles will need slightly more because their tanks are bigger. However, you may need slightly less to completely top your tank up if you’re refilling it just after the warning light came on.

How do you know when you have added enough AdBlue?

Checking your AdBlue® level – Finding out whether you have an adequate amount of AdBlue® in your tank is usually straightforward enough – an amber dashboard warning light will typically alert you when your tank needs a refill. If your warning light is lit, it’s not something that needs immediate action as when it appears, this indicates you have around 1,500 miles to go before you run out, and some models will even display a countdown.

What happens if I add too much AdBlue?

What happens if I put AdBlue in the diesel tank? – Putting it directly into your fuel tank could cause expensive damage to your fuel tank, pump and injection system. If you start the engine it’s likely to be an expensive write-off, so don’t touch the ignition.

Can I overfill my AdBlue tank?

AdBlue tips – If you own, or lease, a modern Euro VI diesel car, you will have to add another fluid, other than petrol and (possibly) oil. AdBlue is a harmless solution, made mainly of pure water and urea, but it can cause serious damage, if dosed incorrectly.

What does AdBlue do? AdBlue is injected into the exhaust system automatically to reduce the harmful NOx exhaust emission element of the diesel combustion process. Many cars will display an AdBlue warning light, the meaning of which must be heeded, by consulting the handbook. When considering how much AdBlue does a car use, driving technique plays a big part but expect 1.5 litres of AdBlue to be consumed every 600 miles.

Yet, the motor trade has alerted us of issues with the system, which we hope to alleviate with these top tips: 1. Do not pour AdBlue into the diesel tank. The car doses AdBlue into the exhaust, to treat the post-combustion gases, not the fuel. To top-up AdBlue, familiarise yourself with the location of the separate tank and its filler.2.

Ask yourself how long does AdBlue last – does AdBlue go out of date? The answer is yes. Never use AdBlue after its expiry date has passed and, unless you cover very high mileages, do not stockpile large quantities at home.3. Ultra-violet light speeds up AdBlue’s deterioration and this can damage your exhaust system’s delicate catalyst.

Therefore, buying bottles that have been sitting outside a petrol forecourt may not be a good idea and could cause AdBlue problems. Instead, look for bottles that have been stored indoors, or in the dark.4. Do not ignore AdBlue refill messages. The engine may stop running and might not start again, even after you have refilled the tank.

It may not be possible to reset the AdBlue warning without professional diagnostic equipment.5. Can you overfill the AdBlue tank? Yes. This situation can create a vacuum inside the tank that prevents the AdBlue from being injected into the exhaust initially and this could cause the AdBlue light to remain on after filling.

In some cars, the AdBlue pump and circuitry are located on top of the tank, so overfilling risks moisture contamination that can damage the circuits.

How far can you drive with low AdBlue?

Adblue – Top It Up Early! – This lack of familiarity with adblue can lead to another mistake – not topping up the adblue early enough when the light comes on. When it comes to warning lights on the dashboard, we react to some differently than others. Many of us treat the low fuel warning light as a game of brinksmanship – we see just how low it’ll go before we fill up.

Something we wouldn’t normally do when the low oil warning light comes on – The oil gets our immediate attention! The low washer fluid warning? How many of us will swear “It’s only just come on Officer” (despite being dry for weeks). So when should you top up the adblue? Most vehicles which require adblue will give you a warning when there’s about 2-3 litres left.

Depending on the vehicle and how you drive it, this will give you about 1,200 to 1,500 mile range. Some vehicles will give you a countdown in miles, or the number of times the vehicle will start before you it will refuse to work. Maybe both. It’s important to treat such warnings as your cue to top up the adblue now (like you would with oil), rather than like a countdown to put off for as long as you possibly can (like you ‘might’ be guilty of with fuel).

  • The reason for this is linked to the reasons for adblue being used in the first place.
  • Vehicle manufacturers are legally obliged to make sure their vehicles limit the emission of harmful gases and particulates.
  • Adblue is not physically required to run an engine, but running an engine without it will cause the vehicle emissions to exceed what’s legally permitted, so the vehicles are programmed to refuse to start if it runs out.

Some will restrict performance if the adblue runs low, again to reduce emissions. Some adblue systems will need the system purging or resetting if allowed to get too low or to be allowed to run out. This will almost always have to be done by a main dealer.

Occasionally the systems are a bit over zealous and even ‘slightly low’ adblue levels will cause the vehicle to continue counting down to the point it will refuse to start, even after being topped up. This forces a trip to the main dealer, possibly risking needing recovery if the vehicle refuses to start.

Bear in mind a trip to a dealer to get this reset costs on average £300. Additionally, the diesel particulate filter (DPF), which is also part of the exhaust system, can clog up faster and/or refuse to ‘regen’ (clear itself) when the adblue is low. Above 50% blocked this filter can’t clear itself and will need to be replaced.

  • Replacement typically costs around £1,500 for the job! None of the above is covered under the warranty, so if this is a car or van hired from us, we’d ultimately have to pass this cost on and no-one wants that.
  • Whether or not this is certain manufacturers using environmental concerns in order to generate additional revenue is not something we’ll comment on! But it serves as all the more reason to follow the sage advice from our Head Technician Kieron Hough and top up the adblue as soon as the light comes on rather than waiting to the tail-end of the countdown!

What happens if you run out of AdBlue while driving?

What happens if your car runs out of AdBlue? If you run out of AdBlue while you’re driving, then the engine’s power and performance will be reduced to ‘limp home’ mode to limit its emissions and once the engine has stopped, it won’t re-start until the AdBlue tank is refilled.

How long should a bottle of AdBlue last?

How Long Does it Last? – The average distance that a full tank of AdBlue will last is 6,000 to 7,000 miles, Typically, 1 litre lasts for around 600 miles but your driving style may impact this. Since travelling between 6,000 and 7,000 miles will empty your tank, we recommend topping up every 5,000 miles just in case. The last thing you need is to run out and get stuck in the middle of nowhere.

What happens if I overfill my DEF tank?

COMMON DEF PROBLEMS – Diesel Exhaust Fluid quality can be affected by:

Crystallization: Crystallization can occur in a couple of ways – over-dosing and hard water top ups. Over-dosing occurs when too much DEF is added to the system – the DEF may not fully hydrolyze which can lead to crystalized deposits in the exhaust or injector nozzle. Over-dosing can result from a partially open DEF injector nozzle, plugged DEF lines or DEF pump issues. Topping up your DEF system with hard water can also result in scale or deposits forming. Dirt / Metal Contamination: Contaminated DEF can cause abrasion of the DEF pump. Dirt, rust or tank scale can occur with improper of DEF (e.g. res-using disposable DEF containers). UREA Concentration (Dilution): Diluted DEF (too much water) reduces its NOx neutralization effectiveness. Most DEF is sold pre-mixed but topping up with water will affect concentrations (and could also lead to crystallization as noted above). Cold Weather: DEF may gel or freeze in colder climates (12ºF (-11ºC)) preventing engine operation. Additives should not be used to thaw DEF as additives can throw off the concentration of the fluid and damage the SCR system. Other Fluids: Contamination of the DEF tank from other fluids such as diesel fuel, coolant, or engine oil being added can cause damage to the SCR system and engine shutdown.

What happens if I overfill my diesel tank?

Car Damage – These systems are only designed to work with vapors, not liquids. If you overfill your tank, it can cover the vapor intake hole with liquid gas, which can then be sucked into the charcoal canister. This can damage the canister and possibly other parts of the system, which will cause the car’s check-engine light to come on and could potentially cost hundreds of dollars to repair.
