AdBlue in a Diesel Tank in North End? Don't Start It

Engine off, ignition off: that's how you begin if AdBlue has got into the diesel tank. Chemically, AdBlue is simply urea in water. The trouble begins once it is pulled through your pump — it will not ignite, and it will not combine with diesel. If the engine has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly cleaned where the vehicle stands around North End. Before anything, phone us on 0333 366 0103.

AdBlue in the diesel tank in North End: the first few minutes

To do:

  • Keys out — that way nobody can power anything on.
  • Close to moving traffic? Then put the hazards on.
  • Keep the till receipt or the empty bottle, so you can tell us what was put in and roughly how much.
  • Call just where you are. Quote a PE7 3 postcode or the closest street name, and nobody has to search for you.

Not to do:

  • Not even for a second, and not to roll your car: the engine remains off.
  • The ignition stays off: on lots of diesels, turning it on is enough to start your fuel pump.
  • Do not top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.
  • Any driving at all is best avoided, including a short way along George Street.
  • No draining it yourself, at all, on the verge.

Ask the attendants to help you roll your vehicle away from the pumps if you are on a forecourt in North End, whether it is the JET or elsewhere. At your own drive, don't touch it at all.

What does AdBlue do in a diesel tank?

Not your motor but the exhaust is where AdBlue belongs. Its own reservoir holds it, and from there it's fed into your exhaust, where it cleans the gas. Nothing inside an injection pump is made for this fluid — and none of it was intended to go through one.

Inside a diesel tank it behaves really differently from fuel. It doesn't mix in. It is heavier than diesel, and so it sinks and collects at the bottom of that tank, which is where the pickup pulls fuel from. Simplest of all: one that had AdBlue in Caldecote overnight and has not been started since. The liquid sits at the base of that tank, untouched — though it will be first through once the motor runs, before any diesel at all.

Two kinds of damage follow from there. What is left once the water goes is urea, which forms crystals: they lodge in tiny passages and block filters. Worse, it eats at certain metals in a fuel system, and carries on till it's cleared out. A vehicle left sitting in North End with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. And there is the water: it brings no protection to the parts that rely on it the most — the injection pump and each injector.

Draining AdBlue from a diesel tank in North End

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

Petrol pumped into a diesel on BP's forecourt leaves the fuel watery — that's the main issue. Damage just comes from driving on it. Blended into your diesel and left inside the tank, it causes none.

The trouble with AdBlue in a diesel is a completely unsuitable liquid. Since it does not burn, running it through isn't an option. Whether your vehicle sits in Denton or the heart of North End, firing it up "to see" costs more in this case than nearly any other error, and the flush counts more. The reasons: it won't remain mixed, so watering it down fails; and crystals and corrosion survive the next fill.

With AdBlue, the good news is no distinct from petrol. If the motor hasn't run, the AdBlue is still in that tank, and your tank is the simplest part of a fuel system to clear, wherever across Cambridgeshire the vehicle is sitting.

How does AdBlue end up in a diesel tank in North End?

Many cars place the AdBlue filler beside the diesel one, occasionally under one flap, and after dark the two may appear identical. Nobody means it. It usually occurs at home, from a bottle bought en route home, not at the forecourt.

A few familiar ways account for most cases. The refill gets rushed outside Stilton Church of England Primary Academy, because the dash lit up with a warning as the kids were dropped off. In the evening, a container goes in on a drive near Mill Road. Or your car is topped up in the car park outside The Stilton Cheese Inn, in poor light, by somebody who has never opened that flap before.

It happens most in the vehicles drivers know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. Wherever you are in North End or the rest of Cambridgeshire, it is the same slip and the same first answer: leave it off.

Already started your engine with AdBlue in the diesel tank in North End?

In that case, the AdBlue is no longer inside the tank. Your filter and lines have had it pulled along, and any running carries it on to the high-pressure pump and every injector.

Perhaps coming back from Folksworth Fun Park, or midway across North End, the engine might run lumpy, smoke, drop power, light up your dash or stall. Stop as soon as it is safe, switch off, and don't restart the car to check. Each start pulls more of that through.

If you were on the A1(M), under a mile from North End, come off at the next exit and stop somewhere safe instead of pressing on.

Every mile pushes the AdBlue further into your system. That's why crossing North End to park near Village Sign and a drive of under 10 miles for Peterborough are very different jobs. Roughly how far it had come is worth telling us.

Wherever the car came to a stop is where all of it gets done, even with more to rinse out once the engine has been started. Long-term damage is very rare when it is noticed soon.

Emptying AdBlue in a diesel around North End: what it takes

Wherever it has come to rest in North End — a forecourt, a lay-by, a drive, a road beside The Parish Meeting Room — the van comes to the vehicle. Three replies decide the work, so before anything else our engineers ask what went in, about the amount, and whether your motor has run.

Then that tank is drained where your car waits, and so the contaminated fuel and the AdBlue come out together. Residue from AdBlue will not wash away by itself, so the whole system gets a careful flush, which counts far more with urea than with petrol. A test of your vehicle follows at the end, after fresh diesel goes in and your filter gets cleaned or, where necessary, replaced. Engine not run? In that case expect roughly half an hour once we are there for most jobs. Our equipment is explosion-proof, and so a live filling station is no problem, and it is quiet enough for a residential street after dark.

Lastly, the system is primed with clean diesel. Then our engineers fire it up and you drive off, whether from a parking bay at Peterborough or a driveway around North End. The check before we head off is that it runs properly on new diesel. No garage is required at any stage, with the whole job done then and there. Afterwards, there is paperwork for your insurer: a VAT invoice plus a written report from the engineer.

About North End, briefly

North End is a suburban area located in Cambridgeshire, situated approximately 5.8 miles from Peterborough and 68.5 miles from London. North End sits in a low-lying inland area at an elevation of around 20 metres, with nearby places including Stilton, Norman Cross, and Folksworth. North End is characterised by its predominantly detached housing stock, which reflects the area's residential nature.

AdBlue drains across North End and Cambridgeshire

Stilton, Norman Cross and Folksworth are among the places around North End that the same vans serve, along with much of Cambridgeshire beyond, throughout the PE postcode area. Close to a boundary, or somewhere tricky to pin down? Checking beats guessing, so ring.

Wherever the car stands — a drive at home, a side street, a car park, a forecourt — our engineers drain it on the spot, with no need to take it to us; that suits North End, a residential suburb, well.

What AdBlue in a diesel tank costs to put right around North End

Each job is different, and so not one fixed price would be fair. What changes the price is, firstly, whether your engine has been running and for how long; then how much AdBlue was put in; and then where your car is and whether our van can reach it safely, which is simpler on an open driveway than in a tight space behind Church Meeting Room.

With that in mind, each call from North End begins with the identical trio — which fluid got in, what quantity, if the engine ran — ahead of a figure. Those answers shrink a range down to a single number.

You get that price on the phone, before anyone heads out, and you pay on the day, by card or over the phone, with nothing upfront. Check your insurance whilst we are on the way: plenty include misfuelling cover.

North End: still alongside the car?

Then the most helpful thing you can do is nothing to the vehicle. Motor off, keys out, ignition off. Tell us it was AdBlue, about what quantity, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel handles it, in North End or wherever within Cambridgeshire.
