Don't Start It: AdBlue in a Diesel Tank in Chinnor
AdBlue in your diesel tank? Then keep your engine off — and the ignition too. Urea dissolved in water is what AdBlue is. The harm starts once it is sucked through your lines — it will not ignite, and it will not blend with diesel. Caught before your motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is in Chinnor. Phone 0333 366 0103 before you do anything else.
Chinnor, AdBlue in your diesel tank: what to do at once
Do these:
- Pull your keys out, and so nobody switches the ignition on.
- Close to moving traffic? Then put your hazards on.
- Keep the till receipt or the empty bottle, so you can tell us what was put in and about how much.
- Our van locates you fastest with a postcode starting OX39 4, or simply the name of a street close by, so call from the car.
Not to do:
- Do not start the motor, even for a moment to move the car.
- Your ignition stays off: on lots of diesels, switching it on is enough to start your pump.
- Pouring in extra diesel does not work: AdBlue settles out instead of thinning.
- Any driving at all is best avoided, including a short stretch down Keens Lane.
- No draining it yourself, either, on the verge.
Rolling your car away from the island is a job for attendants to help with, whichever Chinnor forecourt you are on, the The Co-operative or any other. On your own driveway, do not move it at all.
AdBlue in a diesel tank: what it does
Made for the exhaust, AdBlue has no place in your engine. It goes into its own tank and is sprayed into your exhaust gas to clean it. Not one side suits the other: urea does not belong in an injection pump, and an injection pump cannot take urea.
Poured in with your diesel, it keeps apart rather than mixing — quite unlike fuel. It's heavier than diesel, and so it sinks and gathers at the bottom of your tank, which is where the pickup draws fuel from. Simplest of all: a vehicle that got AdBlue in Henton overnight and has not been started since. The liquid sits at the base of the tank, undrawn — but it would be the first thing through if the motor starts, before any diesel at all.
It does two kinds of harm from there. It eats at some metals found in fuel components, working on any part it touches until it is removed completely. And once the water evaporates, the urea turns into crystals that block filters and lodge in narrow passages. A motor left standing in Chinnor with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. Water lubricates nothing. The high-pressure pump and every injector depend on diesel running past them, and so the water part harms them by itself.
Why is AdBlue in a diesel often the bigger problem?
A problem of thinned fuel is what you get from filling a diesel with petrol from the Shell. Mixed into your diesel and left still, it's harmless for now; using your engine is the harm.
With AdBlue in a diesel, the fluid itself is simply the wrong one. It can't simply be run through, because it doesn't burn. Whether the vehicle sits in Crowell or the heart of Chinnor, turning it over "to see" does more harm in this case than nearly any other slip, and the flush matters more. The reasons: it will not stay blended, so diluting it fails; and deposits and corrosion outlast the next tankful.
The same good news holds as with petrol. Clearing a tank is the simplest job on a fuel system, and with no start-up, the AdBlue stays in it — wherever around Oxfordshire your vehicle sits.
Chinnor: how AdBlue ends up in a diesel tank
In dim light, two caps side by side — the AdBlue cap and the diesel cap, now and then behind one flap — may look the same. Nobody means it; many layouts allow it. A bottle bought while driving home and poured in outside the house, instead of at the forecourt, is the usual route.
Usually, it takes place in one of a couple of familiar ways. A warning light comes on during the school run, and the top-up takes place in a hurry outside St Andrew's Church of England Primary School, Chinnor. A bottle is poured in at the end of the day on a drive just off Church Road. Or the car is topped up in the car park at The Crown, in poor light, by a person who has never opened that flap before.
The least familiar vehicles see it the most — rentals, new ones, company cars, and the other car of a home with one of each fuels. Keep it off: that's the first response to an identical mistake, anywhere around Chinnor or the remainder of Oxfordshire you happen to be.
AdBlue in the diesel tank in Chinnor, and the engine started?
Then the AdBlue has left that tank. Via the filter, through the pipework, and — given any running — on to the high-pressure pump and each injector: that's how far it travels.
Lumpy running, smoke, lost power, dashboard warnings or stalling: each may appear, perhaps midway across Chinnor or returning from Donkey Lane Community Orchard (WIP). Pull over when safe. Switch off. Keep the vehicle off rather than restarting it to check. Each start pulls more of it through.
On the M40, under 3 miles from Chinnor, the next junction is where to leave, and somewhere safe is where to park — not carrying on.
Each mile carries the AdBlue further in. That is why crossing Chinnor to park beside The Village Centre and a drive of under 25 miles towards Oxford are such distinct jobs. Roughly how far had it come? Tell us.
Wherever your car came to a halt is where all of it gets done, even with more to flush after the motor has been started. Permanent damage is very uncommon if it is spotted quickly.
What draining AdBlue from a diesel involves around Chinnor
A street beside St. Andrew's Church Hall, a drive, a lay-by or a filling station: wherever your car has come to rest around Chinnor, our engineers travel to it. Before anything else our engineers ask what got in, about how much, and if your engine has run, because those replies determine this work.
Then your tank is cleared where your car stands, so the tainted fuel and the AdBlue come out together. Residue from AdBlue will not wash away by itself, and so the whole system gets a careful flush, which matters much more with urea than with petrol. Fresh diesel goes in once your filter is flushed — or swapped, if it needs to be — and after that your vehicle is tested. About half an hour once we arrive is usual for most jobs when your motor has not run. The equipment is explosion-proof, so a live forecourt is no fault, and it is hushed enough for a residential street late at night.
Finally, your system is bled with fresh diesel. Firing it up comes next, and then you drive off from where the car is parked, by Princes Risborough or on a drive around Chinnor. Our technicians confirm it runs correctly on new diesel before leaving. The entire job is done where your car is, so it never has to be taken to a workshop. Insurers want a VAT invoice and an engineer report, and both come afterwards.

AdBlue drains across Chinnor and Oxfordshire

What AdBlue in a diesel tank costs to put right in Chinnor
Because each callouts differ, a single price wouldn't be honest. The cost changes first with how long, if at all, your engine has been running, and next with the amount of AdBlue that went in. After that it depends 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 Saint Andrew's.
For that in mind, every enquiry from Chinnor opens by asking the identical trio — what was put in, how much, whether it ran — ahead of a quote. The replies turn a range into a straight price.
The price is given during the call, before anyone sets off; settling up happens on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
