Don't Start It: AdBlue in a Diesel Tank in Bedford
Motor off, ignition off: that is where you start if AdBlue has gone into the diesel tank. AdBlue is urea dissolved in water. The trouble begins once it is pulled through the lines — it won't burn, and it won't blend with diesel. If your motor has not run yet, AdBlue in a diesel tank is usually drained and carefully flushed where your car stands in Bedford. Nothing comes before ringing 0333 366 0103.
Bedford, AdBlue in your diesel tank: what to do right away
Do:
- Remove your keys, and that stops anyone switching the electrics on.
- Put the hazard lights on if you're anywhere near moving traffic.
- The empty bottle or the receipt shows us the product and the amount, so do not bin it away.
- Ring us from where you are. A postcode starting MK40 1, or the name of the closest street, brings our van to you without a search.
Do not do these:
- Do not start the motor, even for a moment to move the car.
- Turning the key to ignition alone sets your pump running on plenty of diesels. Avoid it.
- Pouring in extra diesel does not work: AdBlue separates out instead of blending.
- Keep the vehicle where it is instead of driving it anywhere, even a short stretch down Silver Street.
- No draining it yourself, at all, at the verge.
On a forecourt around Bedford, whether it's the Esso or another one, ask the staff to help you push the car away from the petrol pump. If you are on your own drive, leave it precisely where it sits.
What does AdBlue do in a diesel tank?
Meant for your exhaust, AdBlue has no business in your motor. Stored in a dedicated tank, it is injected into the exhaust stream to treat the gases. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Fuel blends; AdBlue, once poured in, won't. The behaviour is not at all like diesel's. It drops, since it is heavier than diesel, and settles low where the pickup takes its fuel from. Easiest of all: a vehicle that got AdBlue in Putnoe last night and hasn't turned since. The liquid sits at the base of that tank, undrawn — though it will be first through if the motor starts, before any diesel at all.
Once it's sucked in, the harm comes in two forms. It attacks certain metals used in fuel systems, attacking whatever it reaches till it's removed from the system. And when the water goes, the urea turns into crystals that clog filters and lodge in narrow channels. A vehicle left sitting around Bedford with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. And there's the water: it offers no protection to the components that need it the most — the high-pressure pump and each injector.
Why is AdBlue in a diesel regularly the bigger problem?
An issue of thin fuel is what you get after filling a diesel with petrol from the Shell. It mixes with your diesel, and while it's inside your tank it causes no harm; the harm comes from running the motor on it.
AdBlue in a diesel is a fault of the wrong substance altogether. It doesn't burn, and so it can't just be run through. It does not stay mixed, and so it can't be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than nearly anywhere else, whether your car is in Brickhill or the middle of Bedford.
With AdBlue, the good news is no separate from petrol. Not run? Then the AdBlue waits only in your tank, the easiest section of the entire system to clear, anywhere the car has stopped around Bedfordshire.
AdBlue in a diesel tank around Bedford: how it ends up there
It's not on purpose. Many cars have the AdBlue inlet alongside the diesel inlet, now and then under a single flap, and muddling them up is easy in poor light. A container picked up while driving home and tipped in outside the house, instead of at the filling station, is the typical route.
Usually, it happens in one of a few familiar ways. The top-up is rushed outside Priory Primary School, because your dash flashed with a warning as the kids were dropped in. A driver tips the container in at home, just off Midland Road, as the day ends. Else, after dark by Bar Citrus, your car is topped up by someone opening that flap the first time.
Rented cars, brand-new cars, fleet vehicles, or the spare vehicle in a family with both fuels: the least known vehicles see it most. Wherever you are in Bedford or the remainder of Bedfordshire, it's the same error and the same first answer: leave the vehicle off.
Bedford: started the engine with AdBlue in your diesel tank?
If so, the AdBlue is no longer inside your tank. Through the filter, through the lines, and — with any running time — into the injection pump and each injector: that's how far it travels.
Rough running, smoke, lost power, dashboard warnings or stalling: any might appear, perhaps part way across Bedford or returning from St Mary's Gardens. Stop as soon as it is safe, switch off, and do not restart it to check. With each start, more of that is pulled through.
Bedford lies under 10 miles from the M1; if you were on it, exit by the next junction and pull up somewhere safe instead of driving on.
How far it went counts. A couple of hundred yards across Bedford to the car park by Bedford Central Library is a very different job from a run towards Milton Keynes, under 15 miles away, with the AdBlue reaching further into your system with every mile. Let us know roughly how far it had come.
Once the motor has been started, the flush covers more, and all of it is done where the vehicle has stopped. Lasting damage is very unusual if it's noticed early.
What draining AdBlue from a diesel involves around Bedford
Wherever it has stopped around Bedford — a filling station, a layby, a drive, a street beside Harpur Suite — the van comes to your vehicle. Before anything else our technicians ask what was put in, about how much, and whether your motor has been run, because those replies decide the work.
The contaminated diesel and the urea leave together when your tank is emptied, on the spot. Your system is purged thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If the engine has not run, the majority of jobs take about half an hour once our engineers are there. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.
Lastly, the fuel system is bled with fresh diesel. Firing it up comes next, and then you head off from where the car is parked, outside the nearest station or on a driveway around Bedford. Before we go, our technicians check it's running smoothly with fresh diesel in. The whole job is done where the vehicle is, so it never needs to go to a garage. At the end, you are given the paperwork for the insurer: a VAT invoice and a report from the engineer.

AdBlue drains in Bedford and across Bedfordshire

No moving is needed. In Bedford, a riverside town, a mobile service works: your vehicle is emptied where it stands, be it in a driveway, a side street, a parking area or a filling station.
Bedford: what AdBlue in a diesel tank costs to fix
Since each jobs differ, a single price would not be fair. Whether the engine has been running, and for how long, comes first in what shifts the cost. How much AdBlue went in comes next, and then the location of the car, because an open driveway is simpler for a van to reach safely than a tight space behind Harpur Square.
Ahead of any figure, not after, each call from Bedford opens with the same three checks: the fuel, the amount, plus if it ran. Those replies narrow a range right down to one number.
You get that quote by phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront. Many insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.
Bedford: still alongside the vehicle?
Then the most useful thing you can do is nothing to the car. Keys out; motor and ignition off. Phone 0333 366 0103 then tell us it's AdBlue, about how much, and if it's run. Petrol in Diesel takes it from there, in Bedford or anywhere in Bedfordshire.
