Don't Start It: AdBlue in a Diesel Tank in Newbridge
With AdBlue in your diesel tank, your ignition remains off and so does your engine. Urea dissolved in water is all AdBlue is. Being water-based, it won't ignite and won't blend with diesel; damage just starts once your pump starts pulling it. A drain and a thorough flush, done where the vehicle is in Newbridge, is generally all AdBlue in a diesel tank needs — if it's caught before your engine has been run. Before anything, call us on 0333 366 0103.
Newbridge, AdBlue in your diesel tank: what to do straight away
Things to do:
- Pull the keys out, and so no one switches the ignition on.
- Hazards on, if moving traffic is at all near.
- Which product, and roughly how much volume? Save the bottle or the till receipt, and our engineers can know.
- Ring right where you are. Quote a LL14 3 postcode or the closest street name, and nobody has to search for you.
Do not:
- No starting the motor — not briefly, not to shift your vehicle.
- The ignition remains off: on many diesels, turning it on is enough to start the fuel pump.
- Don't top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
- Keep the car where it is instead of driving it anywhere, even a short stretch down Hill Street.
- Draining the tank on your own beside the road isn't one to try.
Rolling your car away from the pumps is a job for attendants to help with, wherever Newbridge forecourt you are on, the Shell included. On your own drive, do not move it at all.
AdBlue in a diesel tank, and what it does there
Not the engine but the exhaust is where AdBlue is meant to go. Stored in a separate tank, it is squirted into the exhaust to clean the fumes. A fuel pump is not designed to take it, and AdBlue was never intended to travel through one.
Poured in with your diesel, it stays apart instead of blending — entirely different from fuel. It's heavier than diesel, so it sinks and collects at the bottom of that tank, which is where the pickup sucks fuel from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Rhosymedre last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has sucked it in.
Two kinds of harm follow from there. What is left once the water goes is urea, which forms crystals: they settle in narrow channels and block filters. Worse, it attacks some metals in the fuel system, and carries on till it's cleared out. Pipes carrying AdBlue spell damage overnight for a car parked around Newbridge. Just inside the tank, it stays the same. The water in it does damage of its own: the high-pressure fuel pump and the fuel injectors depend on diesel to lubricate them, and water gives them nothing.
Why is AdBlue in a diesel regularly the bigger fault?
Top up a diesel with petrol by mistake over at the Esso, and the issue is diluted fuel. Blended into the diesel and left still, it's harmless at that stage; running your motor is the harm.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. Not burning, it cannot just be run through. Nor can it be watered down, since it separates again — and the following tankful will not rinse away deposits or corrosion. So the flush matters more with AdBlue, and turning your key "to see", in the heart of Newbridge or out in Bryn-yr-Eos, does more harm than almost any other slip.
With AdBlue, the good news is no separate from petrol. Not started? Then the AdBlue waits only inside your tank, the simplest bit of the entire system to empty, wherever the car has come to rest in Wrexham.
How AdBlue ends up in a diesel tank in Newbridge
After dark, two caps side by side — the AdBlue cap and the diesel one, now and then behind one flap — can look the same. No one means it; many layouts invite it. It usually happens at home, from a container bought on the journey home, not at the forecourt.
A couple of familiar ways account for the majority of them. Midway through the drop-off, the dashboard flags it up, and outside Weston Rhyn Primary School the refill is hurried. Close to B5605, someone pours a container in at home after work. Or the vehicle is topped up in the car park at Black Lion, in poor light, by a person who has never opened that flap before.
It comes up the most in a rental, a new car, a fleet motor, or the other car in a family with one of each fuels — the vehicles people use least. Wherever you're around Newbridge or the rest of Wrexham, it's the same error and the same first answer: leave the car off.
Newbridge: started the motor with AdBlue in the diesel tank?
Then the tank is no longer where the AdBlue is. It has been drawn through the fuel filter and the lines, and if the motor ran for any time, it has got to the high-pressure fuel pump and the injectors.
Lumpy running, smoke, dropping power, dashboard lights or cutting out: each may show up, maybe midway across Newbridge or returning from Gelli Wood. No restarting to test: pull over once safe, then switch everything off. Every start pulls more of it through.
Leave the M53, under 25 miles from Newbridge, by the next junction and park safely, rather than driving on.
Every mile pushes the AdBlue deeper into the system. That is why crossing Newbridge to park beside Cefn Mawr Library and a drive of under 10 miles towards Wrexham are such distinct jobs. Approximately 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 clean out once your engine has been run. Noticed quickly, it very seldom leaves long-term damage.
Newbridge: how AdBlue is cleared from a diesel
Wherever it has come to rest in Newbridge — a forecourt, a layby, a drive, a street by Cefn Bank — our van comes to the car. Before anything else our technicians ask what got in, roughly how much, and whether the engine has been run, since those answers decide the work.
On the spot, the tank is then emptied, and both the polluted diesel and the urea come out as one. What remains from AdBlue won't flush out by itself, so the whole system gets a full flush, which matters far more with urea than with petrol. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The majority of these jobs are a half-hour job once our engineers arrive, if your engine has not run. Quiet enough for use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.
New diesel goes in to bleed the fuel system, and that's the last step. You head off as soon as our technicians have fired it up, and it makes no difference whether the vehicle is on a drive in Newbridge or in a space outside Ruabon. We confirm it runs smoothly on fresh diesel before we go. Since the job is done in its entirety where your car is, a workshop never comes into it. You get a VAT invoice and an engineer report later, which is what insurers want.

Newbridge and Wrexham: AdBlue drains across the area

What does AdBlue in a diesel tank cost to sort out around Newbridge?
No single figure would be fair, since each job is different. Whether the motor has run, and for how long, comes first in what moves the price. How much AdBlue went in comes next, and then the position of the car, since an open drive is simpler for our van to reach safely than a tight spot behind St John's.
With that in mind, every call from Newbridge opens by asking the identical trio — which fluid got in, how much, if it ran — ahead of a figure. Those answers turn a range into a straight price.
You hear that price on the phone, before anybody sets off, and you pay on the day, by card or over the phone, with nothing upfront. Look at your insurance while we are on the way: plenty carry misfuelling cover.
