AdBlue in the Diesel Tank in Preston? Keep It Switched Off
With AdBlue in your diesel tank, the ignition remains off and so does your engine. Water with urea dissolved in it: that is AdBlue. The trouble starts once it is pulled through your lines — it will not ignite, and it won't combine with diesel. Caught before your motor has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the vehicle is in Preston. Before anything, phone us on 0333 366 0103.
Your next steps straight away, Preston: AdBlue in the diesel tank
Do these:
- Keys out — that way nobody can switch anything on.
- Close to moving traffic? Then put the hazards on.
- Which fluid, and about what quantity? Save the bottle or your receipt, and we can see.
- Call us from where you are. A postcode starting SY4 4, or the name of the closest street, brings the van to you without a search.
Things not to do:
- Moving your vehicle even a few yards is no reason to start the engine.
- Turning your key to ignition alone starts your pump running on many diesels. Avoid it.
- No extra fuel on top. The AdBlue won't mix, and so it is wasted.
- Never drive the car anywhere, not even a short stretch along A5.
- Emptying that tank yourself beside the road isn't worth trying.
Rolling the car away from the pumps is a job for staff to help with, wherever Preston forecourt you are on, the Shell included. Parked on your own drive? Then it remains exactly as it is.
AdBlue in a diesel tank, and what it does there
Meant for the exhaust, AdBlue has no place in your engine. Its own reservoir keeps it, and from there it's sprayed into your exhaust, and there it cleans the fumes. A fuel pump isn't made to take it, and AdBlue was never intended to go through one.
Fuel blends; AdBlue, after poured in, won't. The behaviour is nothing like fuel's. Denser than diesel, it drops and collects below it — the very spot the intake sucks from. Easiest of all: one that had AdBlue in Upton Magna overnight and has not been started since. The AdBlue waits at the base of your tank, undrawn — though it will be first through if the engine runs, ahead of any diesel at all.
Two kinds of damage follow from there. What remains when the water evaporates is urea, which forms crystals: they settle in tiny channels and block filters. Worse, it eats at some metals in a fuel system, and carries on till it is flushed out. By daybreak, a vehicle sitting around Preston with AdBlue through its pipework grows worse; if it's just in your tank, it doesn't. The water in it causes harm of its own: the high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing.
AdBlue in a diesel: why it's often worse than petrol
Put petrol in a diesel at the Asda and you have a problem of thin fuel. It mixes with the diesel, and while it is in that tank it causes no harm; the damage comes from running your motor on it.
AdBlue in a diesel is a fault of the wrong substance altogether. It can't simply be run through, since it does not burn. It doesn't stay mixed, and so it can't be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether the car is in Monkmoor or the middle of Preston.
As with petrol, there is good news. If the motor has not run, the AdBlue is still inside that tank, and that tank is the easiest part of a fuel system to clear, wherever across Shropshire the car is sitting.
How AdBlue ends up in a diesel tank in Preston
It is not deliberate. Many vehicles keep the AdBlue cap beside the diesel inlet, occasionally under one flap, and muddling them up is simple after dark. Most of the time it happens with a bottle bought on the way home and poured in on the drive, not at the forecourt.
It tends to occur in a few familiar ways. Rushing, outside St Giles CofE Primary School, after a warning lamp came on during the school run, someone refills the car. Near A49, a driver pours a bottle in at home in the evening. Or a driver unfamiliar with that flap refills the car after dark, parked in the car park by the pub in the village.
Rented cars, brand-new vehicles, company vehicles, or the spare car in a home with one of each: the least known cars see it the most. Same mistake, same first step — leave it off — anywhere you happen to be in Preston or the remainder of Shropshire.
Already started the motor with AdBlue in your diesel tank around Preston?
Then the tank is no longer where the AdBlue is. Your filter and lines have had it pulled through, and some running time takes it on to the high-pressure pump and every injector.
You may notice your engine running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Steadmans' Plantation or halfway across Preston. Pull over when safe. Switch off. Leave the car off instead of testing it again. More of it is pulled through with each start.
If you were on the M54, under 10 miles from Preston, come off at the next exit and stop somewhere safe rather than pressing on.
Mileage matters: every mile carries the AdBlue deeper in, and so driving for Wolverhampton, under 50 miles away, makes a far larger job than hopping across Preston to the car park by Nancy's Seat. Let us know roughly how far it had come.
Once your engine has run, the flush includes more, and all of it is done where the vehicle has stopped. Noticed quickly, it very seldom leaves long-term damage.
Preston: how AdBlue is drained from a diesel
The car stays put, whether that is a road near John Davenhill Sports Centre, a driveway, a lay-by or a filling station around Preston, and our van travels to it. What got in, roughly how much, plus whether your motor has been run: our technicians ask first, because those decide the work.
Then the tank is emptied where your car waits, so the polluted fuel and the AdBlue come out together. A careful flush counts far more with AdBlue than with petrol, since what remains won't wash away on its own. Fresh diesel goes in once the filter is flushed — or replaced, when it needs to be — and after that your car is tested. The majority of these jobs are a half-hour visit once our technicians turn up, provided the motor has not run. Our pumping gear is explosion-proof, so a live filling station is no issue, and it's hushed enough for a residential street late at night.
Priming the system with new diesel comes at the end. Whether it's a parking space at Shrewsbury or a drive around Preston, that is where we start it and you set off. It's checked on fresh diesel to be sure it runs properly before our engineers head off. The whole job is done where your car is, so it never has to be taken to a workshop. You receive a VAT invoice and an engineer report later, which is what insurers want.
About Preston, for a moment
Preston is a small hamlet in Shropshire, situated on the riverside at an elevation of 64 metres, with detached housing being the predominant type of accommodation. Preston lies near the villages of Emstrey and Uffington, and is close to Berwick Wharf, in a rural area of the West Midlands. Preston is located approximately 25 miles from Wolverhampton and 136 miles from London. Preston has a population of around 543 residents.
Preston and Shropshire: AdBlue drains across the area
Emstrey, Berwick Wharf and Uffington are among the places near Preston that the same vans serve, together with most of Shropshire further out, throughout the SY postcode area. Assuming doesn't help by a county line or anywhere tricky to pin down; phone and check.
Preston is a rural hamlet, and a call-out drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it sits, and so it never needs to be moved to us.
Preston: what AdBlue in a diesel tank costs to fix
There's no honest single quote, since the jobs are not the same. The cost moves first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it rests on where your car is and whether a van can reach it safely, which is simpler on an open driveway than in a tight space behind Uffington Village Hall.
With that reason, each enquiry from Preston opens with the same trio — what went in, how much, if the engine ran — ahead of any figure. When those are known, a range becomes one firm figure.
Our price is quoted during the call, before a van sets off; payment comes on the day, by card or over the phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
Alongside your car in Preston, still?
Then, do nothing — that's the best step there is. Keys out; motor and ignition off. Tell us it was AdBlue, about what quantity, and if the engine ran, on 0333 366 0103. From there Petrol in Diesel takes over, in Preston or wherever in Shropshire.
