AdBlue in a Diesel Tank in Church End? Don't Start It
With AdBlue in your diesel tank, the ignition remains off and so does the motor. Chemically, AdBlue is simply urea in water. It does not burn, it does not mix with diesel, and the harm it does begins when the fuel system pulls it in. If the motor has not run yet, AdBlue in a diesel tank is generally drained and thoroughly rinsed where your car stands around Church End. Phone 0333 366 0103 before you do anything else.
Your next steps straight away, Church End: AdBlue in your diesel tank
Do:
- Remove the keys, which prevents anyone switching the electrics on.
- Near moving traffic? Then put the hazard lights on.
- Keep your receipt or the empty bottle, and so you can tell us what was put in and roughly how much.
- The van locates you fastest with a postcode starting NN11 6, or just the name of a street close by, and so phone from the spot.
Things not to do:
- No starting your motor — not briefly, not to shift your car.
- The ignition stays off: on many diesels, turning it on is enough to start your fuel pump.
- No more fuel added. The AdBlue won't blend, so it is wasted.
- Don't drive the vehicle anywhere, not even a short way up Becketts Close.
- Beside the road, don't try emptying it on your own.
Get the attendants to help you move the vehicle off the island if you're at a forecourt around Church End, whether it is the Texaco or somewhere else. Stopped on your own driveway? Then it remains exactly as it is.
What AdBlue does in a diesel tank
The motor isn't what AdBlue is made for; your exhaust is. Its own tank holds it, and from there it is fed into the exhaust, and there it cleans the gas. Neither side suits the other: urea does not belong in an injection pump, and an injection pump cannot take urea.
Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. Denser than diesel, it drops and pools underneath it — the very place the intake sucks from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Hinton last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in.
It causes two kinds of damage from there. It eats at certain metals used in fuel components, working on whatever it reaches until it's removed from your system. And once the water goes, the urea forms crystals that clog filters and settle in tiny passages. Overnight, a vehicle sitting in Church End with AdBlue through its pipework gets worse; where it's only inside the tank, nothing changes. Diesel protects the high-pressure pump and every injector as it flows; water gives none of that, and that is a second kind of harm.
Why is AdBlue in a diesel regularly the bigger issue?
Put petrol in a diesel at the another forecourt nearby and you have a fault of thin fuel. No damage is done while it sits unused, mixed into your diesel — only when the motor runs on it.
With AdBlue in a diesel, the liquid as such is plainly the wrong one. It cannot just be run through, since it doesn't burn. It does not stay mixed, and so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Woodford Halse or the middle of Church End.
The good news is the same as with petrol. Anywhere around Northamptonshire your car has come to rest, an unstarted motor means the AdBlue yet inside the tank: the easiest part of a fuel system to clear.
How AdBlue ends up in a diesel tank in Church End
Plenty of motors place the AdBlue filler beside the diesel one, occasionally behind a single flap, and in dim light the two can look identical. Nobody intends it. It mostly takes place outside the house, from a container bought on the journey home, rather than at the filling station.
It tends to happen in a couple of familiar ways. The refill gets rushed outside Byfield School, after the dash lit up with a warning as the children were dropped off. A bottle is poured in at the end of the day on a drive just off The Green. Else, after dark outside The Cross Tree, your car gets refilled by someone using that flap the first time.
It crops up most in a rental, a new motor, a company motor, or the other car in a home with both fuels — the cars people use the least. Wherever you're in Church End or the remainder of Northamptonshire, it's the same error and the same first answer: leave it off.
Started the engine with AdBlue in your diesel tank around Church End?
Then that tank is no longer where the AdBlue is. Given any running time, it goes on to the injection pump and every injector, after passing via your filter and pipework.
You may see your motor running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from The Green or halfway across Church End. Once you safely can, stop then switch everything off — without turning it on again to see. More of it is pulled through with each start.
Church End lies under 10 miles from the M40; if you were on it, leave by the first junction and pull up somewhere safe instead of carrying on.
Hopping across Church End to the car park by Holy Cross is one thing; heading towards Coventry, under 25 miles away, is something else, since each mile pushes the AdBlue further in. So distance counts. About how far it had come is worth telling us.
We do all of the cleaning where the vehicle has ended up, and once the engine has been run there is more of it. Very seldom does it leave long-term damage if it is caught quickly.
What does an AdBlue drain on a diesel involve in Church End?
The car remains put, whether that is a road near Byfield Scouts Club, a drive, a lay-by or a filling station in Church End, and our van comes to it. Before anything else our engineers ask what went in, roughly how much, and if the motor has run, since those replies decide the work.
Then that tank is drained where the car sits, so the polluted fuel and the AdBlue come out together. A careful flush matters far more after AdBlue than after petrol, since what remains will not wash away on its own. A test of your car follows at the end, after clean diesel is added and the fuel filter gets cleaned or, where needed, swapped. If the engine has not run, the majority of jobs take about half an hour once our technicians are there. Our equipment is explosion-proof, so a busy forecourt is no fault, and it's quiet enough for a residential street late at night.
Bleeding the system with new diesel comes at the end. Whether it is a parking space by Banbury or a driveway in Church End, that is where our technicians start it and you drive off. It's tested on fresh diesel to be sure it runs properly before our engineers head off. Because the job is done in full where the vehicle is, a workshop never comes into it. You receive a VAT invoice and an engineer report after that, which is what insurers want.
About Church End itself
Church End is a suburban area in Northamptonshire, situated inland at an elevation of around 150 metres. Church End lies approximately 19.7 miles from Coventry and 66.1 miles from London, placing it within commuting distance of major cities. Church End is characterised by its predominantly detached housing stock, with nearby villages such as Byfield and Westhorp also forming part of the local community. Church End has a population of around 999 residents, making it a small but distinct suburban area.
Church End and Northamptonshire: AdBlue drains across the area
AdBlue call-outs in Church End are passed to vans that cover the places around it — Byfield, Westhorp as well as West Farndon — and much of Northamptonshire further out, throughout NN postcodes. Phone and ask rather than guess when you're close to a border, or anywhere tricky to explain.
No moving is needed. In Church End, a residential suburb, a mobile service works: your car is emptied on the spot, whether on a drive, a side street, a car park or a filling station.
What does AdBlue in a diesel tank cost to sort out in Church End?
No flat price would be fair, because each job differs. The cost shifts first with how long, if at all, the motor has been running, and next with the amount of AdBlue that got in. After that it rests on where your car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight gap behind Byfield Bowls Club.
What went in, what quantity, plus whether the engine ran: every Church End call opens with exactly that, before a quote, never afterwards. Their replies narrow the range right down to a single figure.
Quoted by phone before the engineer heads out, it is settled on the day — card or phone, no deposit. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
