Don't Start It: AdBlue in a Diesel Tank in Hughenden Valley
AdBlue in the diesel tank? Then leave the motor off — and your ignition too. AdBlue is urea mixed in water. Unlike fuel, it neither burns nor blends, and nothing happens till your motor pulls it through. Caught before your engine has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is around Hughenden Valley. Before you do anything else, call 0333 366 0103.
Hughenden Valley, AdBlue in the diesel tank: what to do at once
Do:
- Pull your keys out, and so no one switches your ignition on.
- Hazards on, if moving traffic is anywhere near.
- Which product, and about what quantity? Hang on to the bottle or the till receipt, and we can see.
- Ring us from where you are. A postcode starting HP14 4, or the name of the closest street, brings the van to you without a search.
Don't:
- Not even for a second, and not to shift your vehicle: your engine stays off.
- Your ignition remains off: on many diesels, switching it on is enough to run your fuel pump.
- Adding extra diesel doesn't help: AdBlue separates out instead of blending.
- Never drive it anywhere, not even a short way up Orchard Close.
- Beside the road, don't try emptying it on your own.
The attendants on duty at any Hughenden Valley forecourt — the Esso among them — will usually help rolling it clear if you ask. If you're on your own drive, leave the vehicle exactly where it sits.
What does AdBlue do in a diesel tank?
The motor isn't what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into your exhaust gas to clean it. A fuel pump isn't designed to cope with it, and AdBlue was never intended to travel through one.
Poured in with the diesel, it stays separate instead of blending — entirely unlike fuel. Denser than diesel, it sinks and pools below it — the very spot the intake sucks from. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Upper North Dean last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.
It causes two kinds of harm from there. It attacks certain metals used in fuel systems, attacking whatever it touches till it's removed completely. And when the water evaporates, the urea forms crystals that block filters and settle in narrow passages. A motor left standing around Hughenden Valley with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. And there is the water: it offers no lubrication to the components that need it the most — the injection pump and every injector.
AdBlue in a diesel: why it is commonly worse than petrol
Fill a diesel with petrol in error at the Shell, and the issue is diluted fuel. It mixes with your diesel, and whilst it's in your tank it causes no damage; the harm comes from running your motor on it.
AdBlue in a diesel is an issue of the wrong substance altogether. Not burning, it cannot simply be run through. It does not stay mixed, and so it can't be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether your car is in Hunts Hill or the middle of Hughenden Valley.
As with petrol, there's good news. Clearing a tank is the simplest part on a fuel system, and without running, the AdBlue stays in it — wherever in Buckinghamshire the vehicle sits.
Hughenden Valley: how AdBlue ends up in a diesel tank
In dim light, two caps together — the AdBlue cap and the diesel cap, occasionally behind one flap — may look the same. No one intends it; plenty of layouts invite it. Usually it is never the forecourt: someone picks up a bottle heading home and tips it in at home.
It tends to take place in a few familiar ways. Rushing, outside Hughenden Primary School, after a warning lamp came on during the school run, a parent tops up the car. After work, a container goes in on a driveway close to Frogmore Close. Another version: darkness, a pub car park outside The Harrow, and a driver opening that flap for the first time.
Hired motors, new motors, fleet vehicles, or the second car in a family with both fuels: the least familiar vehicles see it most. Wherever you're around Hughenden Valley or the rest of Buckinghamshire, it's the same mistake and the same first answer: leave the car off.
Already started the motor with AdBlue in your diesel tank around Hughenden Valley?
Then your tank is no longer where the AdBlue is. With any running time, it goes on to the high-pressure pump and every injector, having passed via the fuel filter and pipework.
Watch for lumpy running, smoke, falling power, warnings on the dash, or a stall — returning from Theeds Wood, perhaps, or midway across Hughenden Valley. When you safely can, stop then switch it off — with no restarting to see. With each start, more of it is pulled through.
Leave the M40, under 5 miles from Hughenden Valley, by the next junction and park somewhere safe, rather than driving on.
Each mile pushes the AdBlue deeper into the system. That is why crossing Hughenden Valley to park near Hughenden Valley Village Hall and a drive of under 25 miles towards St Albans are such distinct jobs. Let us know about how far it had come.
Once the motor has been started, the flush takes in more, and all of it is done where the car has come to a stop. Spotted early, it very seldom leaves long-term damage.
Hughenden Valley: how AdBlue is cleared from a diesel
Wherever it has come to rest in Hughenden Valley — a forecourt, a lay-by, a driveway, a road by Naphill Village Hall — our van comes to your car. The job rests on three answers, which our technicians get first — what was put in, the quantity, and if your engine has turned over.
The contaminated diesel and the urea come out together when that tank is drained, on the spot. What remains from AdBlue won't flush out by itself, and so the fuel system gets a careful flush, which matters much more here than with petrol. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Most of these jobs are a half-hour job once we arrive, provided the motor hasn't run. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house at night.
Last, your system is primed with new diesel. Firing it up comes next, and then you head off from where the car is parked, outside High Wycombe or on a driveway in Hughenden Valley. Before we leave, our technicians check it is running smoothly with clean diesel in. We do it all wherever the car has stopped, and it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come afterwards.

AdBlue in a diesel tank in Hughenden Valley: the cost of fixing it
There's no honest single quote, since the jobs aren't the same. The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it depends on where the vehicle is and whether a technician can reach it safely, which is easier on an open driveway than in a tight space behind Great Kingshill Village Hall.
For that in mind, each enquiry from Hughenden Valley opens with the identical trio — which fluid was put in, what quantity, if the engine ran — ahead of a figure. Their answers shrink the range down to one number.
Before a van heads out, you are told the quote on the phone. And payment is on the day, card or over the phone, with nothing upfront. As our engineer is on the way, check your insurance: plenty cover misfuelling.
