Moorhole: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in the diesel tank, the ignition remains off and so does your engine. In plain terms, AdBlue is simply urea in water. Not like fuel, it neither ignites nor mixes, and no harm starts until your engine pulls it through. A drain and a thorough flush, done where your car is in Moorhole, is generally what AdBlue in a diesel tank takes — if it's caught before your engine has run. Before you do anything else, call 0333 366 0103.
AdBlue in your diesel tank around Moorhole: the first few minutes
Do:
- Pull your keys out, so no one switches your ignition on.
- Put the hazard lights on if you're anywhere close to moving traffic.
- Keep the receipt or the empty bottle, so you can tell us what was put in and about how much.
- Our van locates you fastest with a postcode starting S20 6, or simply the name of a street nearby, and so phone from the car.
Don't:
- No starting your engine — not briefly, not to shift your vehicle.
- Plenty of diesels run their pump the moment the ignition goes on, and so leave the car off.
- Pouring in more diesel does not help: AdBlue separates out rather than thinning.
- Even a short distance up Moorthorpe Rise is too far to drive it.
- Emptying the tank yourself by the road isn't one to try.
Rolling your car away from the pumps is a job for staff to help with, wherever Moorhole forecourt you are on, the Asda or any other. Stopped on your own driveway? Then it stays exactly where it is.
AdBlue in a diesel tank, and what it does there
Meant for the exhaust, AdBlue has no business in your motor. It goes into its own tank and is sprayed into the exhaust gas to clean it. A fuel pump is not made to take it, and AdBlue was never intended to travel through one.
Fuel mixes; AdBlue, after tipped in, will not. Its behaviour is not at all like fuel's. Denser than diesel, it drops and collects below it — the very spot the intake sucks from. When the system runs, the AdBlue is top of the list to go through. Until then it waits underneath your diesel, which is why a vehicle filled in Birley last night and never switched on stays the simple case, as long as nobody turns the key.
From there it causes two kinds of damage. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps running on the parts it hits for as long as it stays there. A vehicle left standing around Moorhole with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. The water in it does harm of its own: the high-pressure pump and the injectors rely on diesel to lubricate them, and water offers them nothing.
AdBlue in a diesel: why it's often worse than petrol
Top up a diesel with petrol by mistake over at the another forecourt nearby, and the issue is thinned fuel. No harm is done as long as it stays unused, mixed into your diesel — only when your motor works on it.
The issue with AdBlue in a diesel is a totally unsuitable substance. It cannot just be run through, because it doesn't burn. It does not stay mixed, and so it can't be thinned. 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 your motor "to see" costs more here than nearly anywhere else, whether your car is in Ridgeway Moor or the middle of Moorhole.
The same good news applies as with petrol. Wherever across South Yorkshire the vehicle has stopped, an unstarted engine leaves the AdBlue still inside the reservoir: the simplest part of any fuel system to clear.
AdBlue in a diesel tank in Moorhole: how it ends up there
It's not on purpose. Many cars have the AdBlue inlet beside the diesel one, now and then under one flap, and muddling them up is easy in poor light. Mostly it takes place with a bottle bought on the way home and poured in on the driveway, not at the pump.
It tends to occur in a couple of familiar ways. Midway through the drop-off, the dashboard warns, and outside St John Fisher Primary, A Catholic Voluntary Academy the top-up is hurried. Someone pours the bottle in at home, right off Leebrook Drive, as the day ends. Or the vehicle is topped up in the car park at Ridgeway Arms, in poor light, by somebody who has never opened that flap before.
It comes up the most in a hire car, a new car, a company motor, or the spare motor of a family with both fuel types — the cars people use the least. An identical slip, same first response — keep it off — anywhere you are in Moorhole or the remainder of South Yorkshire.
Started the engine with AdBlue in the diesel tank around Moorhole?
The AdBlue has left that tank, then. Given any running time, it travels to the high-pressure pump and every injector, after passing via the filter and pipework.
You may notice the motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Westfield Plantation or halfway across Moorhole. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. Each start pulls more of it through.
On the M1, under 5 miles from Moorhole, the first junction is where to leave, and anywhere sensible is where to park — not driving on.
Each mile carries the AdBlue deeper in. That is why crossing Moorhole to park near Christ Church and a drive of under 5 miles towards Sheffield are very distinct jobs. Roughly how far had it come? Tell us.
Our technicians do all of the cleaning where your car has ended up, and once your engine has been started there is more of it. Very rarely does it leave long-term damage if it's caught early.
Clearing AdBlue in a diesel around Moorhole: what it takes
The car remains where it is, whether that's a road beside Our Lady of Lourdes, a drive, a layby or a forecourt in Moorhole, and our van travels to it. Three replies shape the work, so before anything else we ask which fluid got in, about what quantity, and whether your engine has run.
Then that tank is drained where the car waits, so the polluted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the fuel system is cleaned right through because what remains will not wash away by itself. A test of your car comes at the end, after clean diesel is added and your filter is flushed or, where needed, swapped. The majority of these jobs are a half-hour visit once we get there, provided the engine hasn't run. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.
Last, your system is primed with new diesel. At that point our technicians fire it up and you head off, whether from a parking bay outside Woodhouse or a drive in Moorhole. We make sure it runs correctly on new diesel before we go. The entire job is done where the vehicle is, so it never has to go to a workshop. You get a VAT invoice and an engineer report afterwards, which is what insurers want.

What does AdBlue in a diesel tank cost to sort out around Moorhole?
Not one single price could be fair, since every job is different. The price changes first with how long, if at all, the engine has been running, and next with the amount of AdBlue that went in. After that it turns on where the car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight spot behind Hackenthorpe Community Centre.
Before any figure, not afterwards, each enquiry from Moorhole begins with the same three questions: the liquid, the amount, and if it ran. When they are known, a range turns into one firm figure.
Before a van sets off, you hear the price on the phone. Then payment is on the day, card or by phone, with nothing upfront. While the van is travelling, check your insurance: many include misfuelling.
