Chester: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in your diesel tank, your ignition stays off and so does the motor. Water with urea dissolved in it: that is AdBlue. Not like fuel, it neither ignites nor mixes, and no harm happens till the motor pulls it through. If your motor hasn't run yet, AdBlue in a diesel tank is usually emptied and thoroughly rinsed where your car sits around Chester. Before you do anything else, phone 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around Chester
Things to do:
- So nobody can switch the ignition on, take the keys out.
- Near moving traffic? So put the hazards on.
- So you can tell us which fluid it was and about what quantity, save the receipt or the empty bottle.
- Ring us from where you are. A postcode starting CH1 1, or the name of the nearest street, brings our van to you without a search.
Never:
- No starting your motor — not for a second, not to shift the vehicle.
- Turning the key to ignition alone sets the pump going on plenty of diesels. Skip it.
- No more fuel added. The AdBlue will not blend, so it's wasted.
- Keep it where it is instead of driving it anywhere, even a short stretch along Bridge Street.
- Don't try to drain it yourself at the roadside.
The staff working at any Chester forecourt — the Asda among them — will usually help rolling it aside if you ask. Parked on your own driveway? Then it stays exactly where it is.
AdBlue in a diesel tank, and what it does there
Meant for your exhaust, AdBlue has no place in your engine. Stored in a dedicated tank, it is squirted into the exhaust to clean the gases. A fuel pump isn't designed to take it, and AdBlue was never intended to go through one.
It doesn't blend. After it is tipped into a tank of diesel, AdBlue behaves not at all like fuel. Denser than diesel, it sinks and pools below it — the same spot the intake draws from. Easiest of all: a vehicle that got AdBlue in Boughton overnight and hasn't been started since. The liquid waits at the base of your tank, undrawn — though it would be the first thing through if your engine starts, ahead of any diesel at all.
After it's pulled in, the damage takes two forms. What remains when the water evaporates is urea, which forms crystals: they settle in narrow passages and block filters. On top of that, it eats at some metals in the fuel system, and carries on until it is cleared out. Where the AdBlue is in the lines, leaving it overnight around Chester makes it worse. Inside your tank only, waiting costs nothing. Water lubricates nothing. The high-pressure pump and each injector need diesel flowing past them, and so the water content harms them by itself.
Petrol or AdBlue in a diesel: why AdBlue is commonly worse
Fill a diesel with petrol in error over at the Shell, and the issue is thinned fuel. Mixed into the diesel and left unused, it's harmless for now; using your motor does the damage.
AdBlue in a diesel is a problem of the wrong substance altogether. Not burning, it can't just be run through. It doesn't stay mixed, so it cannot be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether your car is in Dee Banks or the middle of Chester.
As with petrol, there's good news. If your engine has not run, the AdBlue is still in your tank, and your tank is the simplest part of a fuel system to clear, wherever around Cheshire your car is standing.
How does AdBlue end up in a diesel tank in Chester?
Nobody means to do it. The AdBlue filler on plenty of vehicles waits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
A couple of familiar ways account for the majority of them. Hurrying, outside The Grosvenor Park Church of England Academy, after a warning lamp came on during the school run, someone tops up the car. Near The Cross, someone tips a container in on that drive after work. Or a driver new to that flap refills the car after dark, parked in the car park by The Victoria.
It comes up most in a rental, a brand-new vehicle, a company car, or the spare vehicle in a family with both fuel types — the cars drivers know least. Anywhere around Cheshire, Chester as well, the slip does not change, and nor does the first response: leave it switched off.
Started your engine with AdBlue in your diesel tank around Chester?
Then the AdBlue has left the tank. Given any running time, it goes on to the injection pump and each injector, after passing via the fuel filter and lines.
Watch for lumpy running, smoke, falling power, warnings on the dash, or a stall — returning from Cheshire Regiment Memorial Garden, say, or part way across Chester. When you safely can, stop then switch everything off — with no turning it on again to test. Each start pulls more of that through.
Exit the M53, under 3 miles from Chester, at the next junction and park somewhere safe, not driving on.
Distance counts: every mile carries the AdBlue deeper into your system, so heading towards Wrexham, under 15 miles away, gives a far bigger job than hopping across Chester to the car park by Guild Church of St. Peter. Roughly how far had it come? Tell us.
Wherever your car came to a stop is where all of it gets done, even with more to clean out after the motor has been started. Spotted early, it very seldom leaves permanent damage.
What clearing AdBlue from a diesel involves in Chester
Our technicians come to the car, wherever it has stopped around Chester: a side street close to Dewa Roman Experience, a drive, a lay-by or a forecourt. Three answers decide the job, and so first our technicians ask what got in, roughly what quantity, plus if your motor has turned over.
The polluted diesel and the urea leave together after that tank is emptied, on the spot. What remains from AdBlue won't flush away unaided, so the fuel system gets a careful flush, which counts far more with urea than with petrol. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If the engine hasn't run, most jobs take about half an hour once we are there. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house after dark.
Bleeding the system with clean diesel comes at the end. Then our engineers fire it up and you drive off, whether from a parking space by the nearest station or a drive in Chester. Before we leave, we make sure it is running properly with new diesel in. No workshop is required at any stage, with the entire job done on the spot. You get a VAT invoice and an engineer report later on, which is what insurers want.
About Chester itself
Chester is a city situated on the banks of a major river in northwest England, near the border with Wales. It serves as the main settlement in its local area and has a long history as a significant urban centre. Chester is characterised by its riverside location and historic importance, with a notable cathedral at its heart. The city's setting and architecture reflect its rich past as a major town in the region.
AdBlue drains in Chester and across Cheshire
Throughout the CH postcode area, the teams taking AdBlue jobs in Chester reach most of Cheshire too, Newtown, Handbridge and Curzon Park included. Near a border, or somewhere tricky to explain? Asking is better than assuming, so ring.
Wherever the car sits — a drive at home, a side street, a car park, a forecourt — we empty it there, with no need to take it to us; which suits Chester, a cathedral city, well.
What AdBlue in a diesel tank costs to put right around Chester
Not one single price would be honest, because every job differs. Three things move the cost: whether the engine has run and for how long, how much AdBlue got in, and where your car is. That last one turns on whether a van can reach it safely, and an open driveway is simpler than a tight gap behind Roman Strongroom.
Ahead of any quote, not afterwards, every enquiry from Chester opens with the same three checks: the fuel, the amount, plus if the engine ran. Once they are answered, a range turns into a single fixed number.
You hear that quote by phone, before anybody heads out, and you pay on the day, by card or by phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van gets there.
