Deanshanger: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that is where you begin if AdBlue has gone into your diesel tank. Urea dissolved in water is what AdBlue is. Not like fuel, it neither burns nor mixes, and nothing starts until your motor sucks it round. Caught before the motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is around Deanshanger. Before you do anything else, phone 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank around Deanshanger
Do these:
- So no one can turn your ignition on, pull your keys out.
- Put the hazards on if you are anywhere close to moving traffic.
- So you can tell us which fluid it was and roughly how much, keep the receipt or the empty bottle.
- Call us from where you are. A postcode starting MK19 6, or the name of the nearest street, gets the van to you without a search.
Things not to do:
- Shifting the car just a short way is no reason to fire up the motor.
- Do not switch the ignition on. On plenty of diesels that alone runs the fuel pump.
- No extra fuel on top. The AdBlue won't mix, so it's wasted.
- Even a short stretch along Chapel Close is too far to drive the vehicle.
- Draining that tank yourself by the road isn't worth trying.
At a forecourt around Deanshanger, whether it is the BP or another one, ask the staff to help you push the vehicle away from the petrol pump. On that drive, the car remains just where it is.
AdBlue in a diesel tank: what it does
Not your engine but the exhaust is where AdBlue belongs. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Not one side fits the other: urea does not belong in an injection pump, and a pump can't deal with urea.
Poured in with the diesel, it stays apart rather than mixing — entirely unlike fuel. It's heavier than diesel, and so it sinks and collects at the bottom of that tank, which is where the pickup sucks fuel from. Easiest of all: a vehicle that had AdBlue in Old Stratford overnight and has not been started since. The AdBlue waits at the foot of that tank, untouched — but it would be the first thing through once the motor runs, ahead of any diesel at all.
After it is sucked in, the harm comes in two forms. It eats at certain metals found in fuel components, working on any part it touches until it's cleared from the system. And when the water goes, the urea turns into crystals that block filters and lodge in tiny channels. A car left sitting around Deanshanger with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Then there is the water: it brings no protection to the components that rely on it most — the injection pump and each injector.
AdBlue in a diesel: why it's often worse than petrol
Petrol put into a diesel on Esso's forecourt makes your fuel watery — that is the whole fault. Harm only comes from running on it. Blended into the diesel and left in your tank, it causes nothing.
AdBlue in a diesel is another matter: not thin fuel, but no fuel at all. Not burning, it cannot just be run through. Nor can it be thinned, since it splits back out — and the next fill will not rinse away crystals or corrosion. So the flush counts for more with AdBlue, and trying the engine "to see", in the heart of Deanshanger or out in Lower Weald, does more harm than almost any other mistake.
With AdBlue, the good news is no different from petrol. Emptying a tank is the simplest part on a fuel system, and without running, the AdBlue remains in there — wherever across Northamptonshire your vehicle sits.
How does AdBlue end up in a diesel tank in Deanshanger?
In dim light, two caps side by side — the AdBlue one and the diesel cap, occasionally under a single flap — can appear the same. No one intends it; plenty of designs allow it. Mostly it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
It tends to take place in a couple of familiar ways. Hurrying, outside Deanshanger Primary School, after a warning light flashed on during the school run, a parent tops up the car. Someone tips the container in at home, just off High Street, as the day ends. Or a driver unfamiliar with that flap tops up your car in dim light, parked in the car park outside Deanshanger Conservative Club.
The least known cars get it the most — rentals, new ones, company ones, and the spare motor in a family with one of each fuels. Wherever you're around Deanshanger or the remainder of Northamptonshire, it is the same slip and the same first answer: leave the vehicle off.
Deanshanger: started your engine with AdBlue in your diesel tank?
Then the AdBlue has left your tank. Via your filter, through the pipework, and — with any running — on to the high-pressure pump and each injector: that's where it travels.
Maybe returning from Deanshanger Pocket Park, or midway across Deanshanger, your engine may run lumpy, smoke, lose pace, light up your dash or cut out. Once you safely can, stop and turn it off — with no restarting to test. More of it is pulled through with each start.
On the M1, under 10 miles from Deanshanger, the next junction is where to leave, and anywhere safe is where to stop — not carrying on.
Each mile carries the AdBlue deeper into the system. That's why a hop across Deanshanger to park near Deanshanger Methodist Church and a drive of under 10 miles towards Milton Keynes are such different jobs. Let us know about how far it had come.
Once the motor has been started, the flush includes more, and all of it is done where your car has ended up. Permanent damage is very unusual if it's spotted early.
Clearing AdBlue in a diesel around Deanshanger: what it takes
Anywhere it has come to rest in Deanshanger — a forecourt, a layby, a driveway, a street beside Deanshanger War Memorial — the van travels to your car. Three replies shape the job, so first our technicians ask which fluid went in, roughly what quantity, plus if your motor has turned over.
Next, emptying the tank on the spot removes the polluted diesel and the AdBlue together. The system is rinsed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Engine not run? Then count on about half an hour once we are there for most jobs. The pumping gear is explosion-proof, and so a live filling station is no problem, and it's hushed enough for a residential street after dark.
Fresh diesel goes in to prime your system, and that is the final step. Firing it up comes next, and then you set off from where the car is parked, by Wolverton or on a drive in Deanshanger. It is tested on clean diesel to make sure it runs correctly before we go. Because the job is done in full where the car is, a garage never comes into it. You receive a VAT invoice and an engineer report later, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Deanshanger
No single figure could be honest, since each job is different. The cost shifts first with how long, if at all, the motor has been running, and next with the quantity of AdBlue that got in. After that it depends on where your car is and whether a technician can get to it safely, which is easier on an open driveway than in a tight gap behind Holy Trinity.
Before any figure, not after, each call from Deanshanger opens with three questions: the fuel, the amount, and if it ran. With those replies, the range narrows to one fixed number.
Before a van sets off, you hear our price by phone. And payment is on the day, by card or by phone, with nothing in advance. While the van is travelling, dig out your insurance: many cover misfuelling.
