AdBlue in a Diesel Tank in Sundon Park? Don't Start It

With AdBlue in the diesel tank, your ignition stays off and so does your engine. Chemically, AdBlue is simply urea in water. As it is water-based, it will not ignite and never combines with diesel; trouble only comes when the pump starts pulling it. In Sundon Park, AdBlue in a diesel tank found before your motor runs usually comes down to a drain and a thorough flush, right where the vehicle is. Phone 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in the diesel tank around Sundon Park

Things to do:

  • Remove the keys, which stops someone switching the power on.
  • If you're anywhere near moving traffic, put the hazard lights on.
  • The empty bottle or the receipt tells us the product and the quantity, so do not bin it away.
  • Call right where you are. Quote a LU3 3 postcode or the nearest street name, and nobody has to hunt for you.

Do not do these:

  • Don't start your motor, even for a moment to move the car.
  • Your ignition stays off: on lots of diesels, switching it on is enough to start the fuel pump.
  • Do not top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
  • Even a short way up Ashwell Avenue is too far to drive it.
  • Do not try to drain the car yourself by the roadside.

Ask the people behind the counter to help you roll your car away from the pumps if you're on a forecourt around Sundon Park, whether it's the Essar or somewhere else. Stopped on your own drive? Then it remains exactly where it is.

What does AdBlue do in a diesel tank?

Meant for your exhaust, AdBlue has no place in the engine. It goes into its own tank and is sprayed into your exhaust gas to clean it. A fuel pump isn't made to take it, and AdBlue was never supposed to go through one.

It does not blend. After it is poured into a tank of diesel, AdBlue acts nothing like fuel. It drops, because it is heavier than diesel, and settles low where the intake takes its fuel from. Simplest of all: a vehicle that had AdBlue in Leagrave last night and has not been started since. The AdBlue waits at the foot of the tank, untouched — though it will be the first thing through once your engine runs, ahead of any diesel at all.

After it is sucked in, the damage comes in two forms. It eats at some metals used in fuel systems, attacking any part it reaches until it's removed completely. And when the water goes, the urea turns into crystals that clog filters and settle in tiny passages. By daybreak, a car parked around Sundon Park with AdBlue through its pipework grows worse; where it is just inside the tank, it doesn't. Diesel lubricates the injection pump and each injector as it passes; water offers no lubrication, which is a separate form of harm.

AdBlue in a diesel: why it is frequently worse than petrol

An issue of thinned fuel is what you get from fuelling a diesel with petrol at the BP. It mixes with the diesel, and whilst it is in the tank it does no harm; the harm comes from running the engine on it.

AdBlue in a diesel is an issue of the wrong substance altogether. It can't simply be run through, since it doesn't burn. It does not stay mixed, so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than almost anywhere else, whether the vehicle is in Chalton or the middle of Sundon Park.

The good news is the same as with petrol. If the engine has not run, the AdBlue is still in the tank, and that tank is the quickest part of a fuel system to clear, wherever around Bedfordshire the vehicle is sitting.

How does AdBlue end up in a diesel tank around Sundon Park?

In dim light, two caps side by side — the AdBlue cap and the diesel cap, occasionally behind a single flap — may appear the same. Nobody intends it; plenty of layouts allow it. A container picked up while heading home and poured in at home, instead of at the forecourt, is the usual story.

The ways it occurs are few and familiar. The top-up gets hurried outside Parklea Primary School, after your dash flashed with a warning as the kids were dropped off. Close to Rockfield Drive, a driver tips a bottle in at home after work. Otherwise, in dim light by the pub in the village, your vehicle is topped up by a driver using that flap for the first time.

It comes up most in a rental, a brand-new car, a company motor, or the spare motor in a home with one of each fuels — the cars drivers use the least. Wherever you're around Sundon Park or the remainder of Bedfordshire, it is the same mistake and the same first answer: leave the car off.

Sundon Park: started the engine with AdBlue in your diesel tank?

In that case, the AdBlue is no longer in your tank. It has been pulled through the filter and the fuel lines, and if your motor ran for any time, it has reached the high-pressure fuel pump and your injectors.

Expect lumpy running, exhaust smoke, lost power, warnings on your dash, or a cut-out — returning from Leagrave Common, say, or part way across Sundon Park. Once you safely can, pull over then switch everything off — with no turning it on again to test. Every start pulls more of it through.

On the M1, under a mile from Sundon Park, the next junction is where to leave, and somewhere sensible is where to park — not carrying on.

A quick hop across Sundon Park to the car park by St John The Apostle Catholic Church is one matter; heading for St Albans, under 15 miles away, is another, because each mile pushes the AdBlue deeper in. So mileage counts. Roughly how far had it come? Tell us.

There is more to rinse out once your engine has been run, and our technicians do all of it where your car has come to a stop. When it is caught soon, lasting damage is very uncommon.

What clearing AdBlue from a diesel involves in Sundon Park

We come to your car, wherever it has stopped around Sundon Park: a side street close to Sundon Baptist Church Hall, a drive, a lay-by or a forecourt. The job depends on three answers, and we ask for before all else — what got in, the quantity, and whether the motor has run.

The polluted diesel and the urea come out as one after your tank is emptied, right there. The fuel system is cleaned thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. Next, your filter: flushed, or replaced if it must be. Then clean diesel, and then a test of your vehicle. Not run? In that case count on about half an hour on site for most jobs. Low-noise enough to use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.

The final step is to prime the system on new diesel. Starting the engine comes next, and then you set off from where the car is parked, outside Leagrave or on a driveway around Sundon Park. It is checked on new diesel to make sure it runs properly before our technicians go. Because the job is done in its entirety where the vehicle is, a garage never comes into it. Insurers want a VAT invoice and an engineer report, and you get both afterwards.

What AdBlue in a diesel tank costs to put right around Sundon Park

There is no honest single quote, since the jobs aren't the same. Whether your engine has been running, and for how long, comes first in what changes the price. How much AdBlue went in comes next, and then the position of your car, since an open driveway is easier for a van to get to safely than a tight space behind Sundon Baptist Church.

Before any figure, not afterwards, each enquiry from Sundon Park begins with the same three questions: the liquid, the amount, and if it ran. With them, the range narrows to one firm figure.

Priced on the call before the van sets out, the job is paid for that day — card or phone, nothing in advance. Look at your insurance while we're on the way: many carry misfuelling cover.
