Don't Start It: AdBlue in a Diesel Tank in Shotton
If AdBlue has gone into the diesel tank, keep your engine off and keep your ignition off. AdBlue is urea dissolved in water. Being water-based, it will not ignite and won't blend with diesel; trouble only starts once your pump starts pulling it. In Shotton, AdBlue in a diesel tank caught before your engine runs normally means a drain and a thorough flush, just where your car is. Ring 0333 366 0103 before you do anything else.
Your next steps straight away, Shotton: AdBlue in the diesel tank
Do these:
- Keys out — that way nobody can power anything on.
- Near moving traffic? Then put your hazards on.
- The empty bottle or the till receipt tells us the product and the quantity, and so don't throw it away.
- The van finds you quickest with a postcode starting CH5 1, or just the name of a street nearby, and so phone from the spot.
Don't:
- No starting the motor — not briefly, not to reposition your vehicle.
- Many diesels power their pump the instant your ignition goes on, and so leave it off.
- Adding more diesel doesn't work: AdBlue settles out rather than thinning.
- Leave the car where it is instead of driving it anywhere, even a short distance along Norman Street.
- Don't try to drain the car yourself at the roadside.
Rolling your car away from the island is a job for staff to help with, wherever Shotton forecourt you're on, the Esso or any other. If you are on your own drive, leave the car just where it is.
AdBlue in a diesel tank, and what it does there
Meant for the exhaust, AdBlue has no place in your engine. From a dedicated tank it goes directly to your exhaust, treating what the motor emits. Neither side fits the other: urea does not belong in an injection pump, and a pump cannot deal with urea.
Inside a diesel tank it behaves really differently from fuel. It doesn't mix in. The intake sucks fuel from the lowest part of the tank, and that is just where AdBlue settles: being heavier than diesel, it sinks. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Big Mancot last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.
From there it does two kinds of damage. It attacks certain metals found in fuel components, attacking whatever it touches until it's removed completely. And when the water evaporates, the urea turns into crystals that block filters and lodge in tiny channels. Lines carrying AdBlue mean damage by morning for a car sitting in Shotton. Only in that tank, it stays the same. Water protects nothing. The high-pressure pump and every injector depend on diesel running through them, so the water content harms them in its own right.
Why AdBlue in a diesel is often more serious than petrol
Put petrol in a diesel at the Asda and you have a problem of thin fuel. It mixes with the diesel, and whilst it's in your tank it does no damage; the damage comes from running the motor on it.
AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all. It cannot simply be run through, because it doesn't burn. Deposits and corrosion stay after the next fill, and AdBlue separates again from your diesel, so watering it won't help. Hence the flush counts more, and trying your engine "to see" does more harm with AdBlue than nearly any other slip — in Pentre or the centre of Shotton alike.
The good news is the same as with petrol. Anywhere across Flintshire your car has stopped, an unrun engine means the AdBlue yet inside the tank: the easiest part of any fuel system to clear.
Shotton: how AdBlue ends up in a diesel tank
No one means to do it. The AdBlue filler on plenty of vehicles sits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.
The ways it occurs are few and familiar. Hurrying, outside Saughall All Saints Church of England Primary School, after a warning lamp flashed on during the school run, a parent tops up the car. Near Central Drive, a driver pours a container in on the drive in the evening. Otherwise, after dark outside The Melrose Inn, the vehicle is topped up by a driver opening that flap for the first time.
It occurs most in the vehicles people know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you are around Shotton or the rest of Flintshire, it's the same mistake and the same first answer: leave it off.
Started the motor with AdBlue in the diesel tank in Shotton?
Then the AdBlue has left that tank. Your filter and pipework have had it pulled through, and some running carries it on to the high-pressure pump and each injector.
Watch for lumpy running, exhaust smoke, lost power, lights on your dash, or a stall — coming back from 33 Club, say, or midway across Shotton. Stop as soon as it is safe, switch off, and don't restart it to check. More of it is pulled through with each start.
If you were on the M56, under 10 miles from Shotton, come off at the next junction and stop somewhere sensible rather than pressing on.
Distance matters: each mile pushes the AdBlue further into the system, so driving for Chester, under 10 miles away, makes a much bigger job than hopping across Shotton to the car park by Elmwood Close Community Centre. Approximately how far had it come? Tell us.
Our technicians do all of the rinsing where your car has ended up, and once your engine has run there is more of it. Spotted soon, it very rarely leaves permanent damage.
Clearing AdBlue in a diesel in Shotton: what it takes
Anywhere it has come to rest around Shotton — a forecourt, a lay-by, a driveway, a street by Aston Park Community Centre — the van comes to your vehicle. The work depends on three replies, and we get first — what got in, the amount, and whether the motor has turned over.
Right there, the tank is then emptied, and all of the polluted diesel and the urea come out as one. What remains from AdBlue won't wash out by itself, and so the whole system gets a full flush, which counts much more here than for petrol. Clean diesel goes in once the filter is flushed — or replaced, if it needs to be — and after that your vehicle is tested. Most of these jobs are a half-hour visit once we arrive, if the engine hasn't run. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark.
New diesel goes in to bleed the system, and that's the final step. Firing it up comes next, and then you drive off from where your car is parked, by the nearest station or on a drive in Shotton. We confirm it runs correctly on fresh diesel before we go. Since the job is done in full where the vehicle is, a garage never comes into it. You receive a VAT invoice and an engineer report afterwards, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right in Shotton
Not one single figure would be honest, since each job differs. The cost changes first with how long, if at all, the engine has been running, and next with the amount of AdBlue that got in. After that it rests on where the car is and whether a technician can reach it safely, which is simpler on an open drive than in a tight space behind Ty Calon Community Hub.

The price is quoted on the call, before a van sets off; payment comes on the day, by card or by phone, with nothing upfront. Check your insurance whilst we're on the way: plenty carry misfuelling cover.
