Don't Start It: AdBlue in a Diesel Tank in Moreton Morrell

If AdBlue has got into the diesel tank, leave your motor off then keep your ignition off. Urea dissolved in water is all AdBlue is. It doesn't burn, it does not mix with diesel, and the damage it does starts when the fuel system pulls it in. In Moreton Morrell, AdBlue in a diesel tank found before your engine runs usually means a drain and a thorough flush, just where the car is. Ring 0333 366 0103 before you do anything else.

Moreton Morrell, AdBlue in your diesel tank: what to do straight away

Things to do:

  • Take your keys out, and so no one switches your ignition on.
  • Put your hazards on if you are anywhere close to moving traffic.
  • So you can give us which fluid it was and about what quantity, keep the till receipt or the empty bottle.
  • Ring us from where you are. A postcode starting CV35 9, or the name of the nearest street, gets our van to you without a search.

Not to do:

  • Not even for a second, and not to shift the car: your engine remains off.
  • Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump.
  • No extra fuel on top. The AdBlue will not blend, and so it's wasted.
  • Never drive the vehicle anywhere, not even a short way along Wilcox Leys.
  • By the road, don't try draining it on your own.

The attendants on duty at any Moreton Morrell filling station — the Shell included — will usually lend a hand pushing it aside if you ask. On your own drive, do not touch it at all.

What does AdBlue do in a diesel tank?

Meant for your exhaust, AdBlue has no business in your motor. Kept in a dedicated tank, it is injected into the exhaust to treat the gases. Nothing inside a fuel pump is made for this fluid — and no part of it was intended to go that way.

Fuel blends; AdBlue, after poured in, won't. The behaviour is nothing like diesel's. It is heavier than diesel, and so it sinks and collects at the bottom of your tank, which is where the pickup pulls fuel from. A motor filled on a driveway in Ashorne yesterday evening and left unstarted counts as the straightforward case. No pump has sucked the AdBlue up so far — but once the motor turns, that is what is pulled first, straight from the bottom of that tank.

It does two kinds of damage from there. It eats at some metals used in fuel systems, attacking whatever it reaches till it is cleared from your system. And when the water evaporates, the urea forms crystals that clog filters and settle in tiny passages. Lines holding AdBlue spell damage by morning for a car parked around Moreton Morrell. Only in the tank, it stays stable. Water lubricates nothing. The high-pressure pump and each injector need diesel flowing past them, and so the water part harms them by itself.

Petrol or AdBlue in a diesel: why AdBlue is often worse

Petrol pumped into a diesel on BP's forecourt leaves your fuel thin — that's the whole fault. Blended through your diesel and sitting still, it is no threat for now; using the engine is the damage.

AdBlue in a diesel is a fault of the wrong substance altogether. It doesn't burn, and so it cannot just be run through. Nor can it be thinned, because it splits back out — and the following tankful won't clear away deposits or corrosion. So the flush counts for more here, and turning the key "to see", in the heart of Moreton Morrell or out in Newbold Pacey, costs more than nearly any other mistake.

The good news is the same as with petrol. If your motor has not run, the AdBlue is still in the tank, and that tank is the easiest part of a fuel system to clear, wherever across Warwickshire the car is sitting.

Moreton Morrell: how AdBlue ends up in a diesel tank

Nobody means to do it. The AdBlue filler on plenty of cars waits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Mostly it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

A couple of familiar ways account for the majority of them. A warning light comes on during the school run, and the top-up occurs in a hurry outside Moreton Morrell CofE Primary School. Near Duffus Hill, a driver pours a container in on that drive after work. Another pattern: dim light, a pub car park by Black Horse, and a driver using that flap the first time.

It happens most in the cars people know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. Same slip, an identical first response — leave it off — anywhere you happen to be in Moreton Morrell or the rest of Warwickshire.

AdBlue in your diesel tank around Moreton Morrell, and your engine started?

Then the AdBlue has left your tank. Given any running, it travels to the high-pressure pump and every injector, after passing through your filter and pipework.

Expect lumpy running, smoke, lost power, warnings on your dash, or a cut-out — coming back from Blackmeadow Spinney, say, or part way across Moreton Morrell. Once you safely can, pull over then switch it off — with no turning it on again to see. More of it is pulled through with each start.

On the M40, under 3 miles from Moreton Morrell, the first junction is where to leave, and anywhere safe is where to park — not driving on.

How far it went counts. A few hundred yards across Moreton Morrell to the car park by Holy Cross is a very different job from a run towards Coventry, under 15 miles away, with the AdBlue reaching further into the system with each mile. Roughly how far had it come? Tell us.

Wherever the car came to a stop is where all of it gets done, even with more to rinse out after the motor has been running. Spotted quickly, it very seldom leaves permanent damage.

Moreton Morrell: how AdBlue is emptied from a diesel

Our technicians come to the car, wherever it has stopped in Moreton Morrell: a side street near Saint George the Martyr, a drive, a lay-by or a forecourt. Three answers shape the job, and so before anything else our engineers ask what was put in, roughly what quantity, plus if the engine has run.

The polluted diesel and the urea leave together after your tank is emptied, on the spot. The fuel system is rinsed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. Next, your filter: flushed, or replaced if it has to be. After that clean diesel, then a check of the car. Engine not run? In that case expect about half an hour once we are there for most jobs. Quiet enough for use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.

New diesel goes in to prime the system, and that is the final step. Whether it's a parking space by Leamington Spa or a drive around Moreton Morrell, that is where our engineers fire it up and you drive off. The check before our engineers go is that it runs correctly on fresh diesel. Because the job is done in its entirety where the car is, a workshop never comes into it. Your insurer is likely to want an engineer's report and your VAT invoice — each handed over once the job is done.

What AdBlue in a diesel tank costs to put right around Moreton Morrell

Each job differs, and so not one fixed quote would be fair. Three things change the cost: whether your engine has run and for how long, how much AdBlue was put in, and where your car is. That last one comes down to whether a van can reach it safely, and an open driveway is simpler than a tight gap behind War Memorial.

Before any figure, not after, every call from Moreton Morrell begins with the same three checks: the liquid, the amount, plus whether the engine ran. Given those replies, a range narrows to a single fixed figure.

Our quote is given during the call, before anyone sets off; payment comes on the day, by card or by phone, with nothing upfront. Misfuelling cover comes with many insurance policies, so it pays to look at yours before the van gets there.
