Carcroft: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has got into the diesel tank, keep your motor off then leave the ignition off. Urea mixed in water is all AdBlue is. Not like fuel, it neither ignites nor blends, and nothing starts until your engine pulls it round. Caught before the engine has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where your car is in Carcroft. First, ring us on 0333 366 0103.
AdBlue in your diesel tank in Carcroft: the first few minutes
Do these:
- Remove your keys, and that stops someone turning the power on.
- Hazards on, if moving traffic is at all close.
- The empty bottle or your receipt tells us the fluid and the amount, so do not bin it out.
- Tell us a postcode starting DN6 8, or whatever street lies nearest, and our van reaches you straight — so ring from wherever you are.
Never do these:
- Shifting the car just a short way is no reason to fire up the engine.
- Your ignition remains off: on many diesels, switching it on is enough to run the pump.
- No more fuel on top. The AdBlue will not mix, and so it is wasted.
- Any driving at all is to be avoided, including a short distance along Owston Road.
- By the road, do not attempt emptying it on your own.
Ask the people behind the counter to help you move the car away from the island if you're at a forecourt in Carcroft, whether it's the BP or elsewhere. If you are on your own drive, leave the vehicle just where it stands.
What does AdBlue do in a diesel tank?
Not your engine but your exhaust is where AdBlue is meant to go. Its own tank holds it, and from there it is sprayed into your exhaust, and there it treats the gas. A fuel pump isn't made to take it, and AdBlue was never supposed to go through one.
Fuel mixes; AdBlue, after tipped in, will not. The behaviour is not at all like fuel's. It sinks, since it's heavier than diesel, and settles down where the intake draws its 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 Owston 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 drawn it in.
After it's drawn in, the harm takes two forms. It eats at certain metals found in fuel systems, working on any part it reaches till it is removed completely. And once the water evaporates, the urea turns into crystals that block filters and settle in narrow channels. A car left sitting around Carcroft with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Water lubricates nothing. The injection pump and every injector need diesel flowing past them, so the water part damages them by itself.
Petrol or AdBlue in a diesel: why AdBlue is regularly worse
Fill a diesel with petrol in error at the JET, and this problem is diluted fuel. It mixes with the diesel, and while it is inside your tank it does no harm; the harm comes from running the motor on it.
AdBlue in a diesel is a fault of the wrong substance altogether. Since it does not burn, running it through is not an option. Whether your car is in Woodlands or the centre of Carcroft, firing it up "to see" does more harm in this case than nearly any other error, and the flush counts for more. The reasons: it will not stay blended, so watering it down is impossible; and crystals and corrosion outlast the following fill.
As with petrol, there is good news. Never started? Then the AdBlue waits only in your tank, the simplest section of the entire system to empty, wherever your vehicle has come to rest around South Yorkshire.
AdBlue in a diesel tank around Carcroft: how it ends up there
Many motors place the AdBlue filler beside the diesel cap, occasionally behind one flap, and after dark the two can look identical. No one intends it. Usually it's not the filling station: someone buys a bottle driving home and tips it in at home.
It tends to take place in a couple of familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside Carcroft Primary School. A bottle is poured in at the end of the day on a drive just off High Street. Or your car is topped up in the car park at Foresters Arms, in poor light, by a person who has never opened that flap before.
It takes place most in the vehicles drivers know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. Wherever you are in Carcroft or the remainder of South Yorkshire, it is the same mistake and the same first answer: leave the car off.
Started your engine with AdBlue in your diesel tank in Carcroft?
Then the tank is no longer where the AdBlue is. It's been pulled through the filter and the fuel lines, and if your motor ran for any time, it has reached the high-pressure fuel pump and the fuel injectors.
Rough running, smoke, lost power, dashboard lights or stalling: each might appear, maybe midway across Carcroft or returning from Owston Hall Golf Course. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. Each start pulls more of that through.
On the A1(M), under 3 miles from Carcroft, the first junction is where to leave, and somewhere sensible is where to stop — not driving on.
A quick hop across Carcroft to the car park by St Michael & All Angels is one thing; driving towards Doncaster, under 5 miles away, is another, because each mile pushes the AdBlue further in. So distance matters. Tell us roughly how far it had come.
Wherever your car came to a halt is where all of it gets done, even with more to rinse out once the motor has been running. Permanent damage is very rare if it's caught soon.
Draining AdBlue in a diesel around Carcroft: what it takes
Our technicians come to your car, wherever it has stopped around Carcroft: a side street near St Laurence, a drive, a lay-by or a forecourt. The work depends on three replies, and our technicians ask for before all else — what got in, the quantity, and if your motor has turned over.
Next, emptying that tank right there takes out the contaminated diesel along with the AdBlue in one go. A full flush counts much more after AdBlue than after petrol, since residue will not wash out on its own. Testing your vehicle follows last, after fresh diesel goes in and the fuel filter is flushed or, if needed, replaced. The majority of these jobs are a half-hour job once our technicians get there, if your engine has not run. Low-noise enough to use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.
The final step is to bleed your system on fresh diesel. Whether it is a parking space at Adwick or a driveway in Carcroft, that is where our technicians fire it up and you drive off. It's tested on fresh diesel to make sure it runs correctly before our technicians leave. 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, which is what insurers want.
About Carcroft, briefly
Carcroft is a suburban area in South Yorkshire, situated near the River Don and close to the town of Doncaster. Carcroft lies at a low elevation of around 10 metres, with Carcroft Common nearby. Carcroft has a mix of housing types, but semi-detached homes are predominant in the area. Carcroft is located near other local places, including Adwick le Street and Skellow, and is around 150 miles north of London.
Carcroft and South Yorkshire: AdBlue drains across the area
Our vans that answer AdBlue call-outs around Carcroft also cover the spots around it, Carcroft Common, Adwick le Street and Skellow among them, and most of South Yorkshire beyond, across the DN postcode area. Guessing won't help by a county line or somewhere hard to describe; ring and check.
Carcroft is a residential suburb, and a mobile drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it stands, so it never needs to be moved to us.
What AdBlue in a diesel tank costs to put right in Carcroft
No single figure would be honest, because every job is different. What moves the cost is, firstly, whether the motor has run and for how long; then how much AdBlue went in; and then where the car is and whether our van can reach it safely, which is easier on an open drive than in a tight space behind All Saints.
That is why each call from Carcroft starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it's run. Those replies turn a range into a straight price.
Our quote is quoted on the call, before anyone sets off; payment comes on the day, by card or by phone, and nothing upfront. Look at your policy whilst we are on the way: many carry misfuelling cover.
Next to the car around Carcroft, still?
Not touching your car is, right now, the best thing open to you. Ignition off, engine off, keys out. Tell us it was AdBlue, roughly what quantity, and whether the engine ran, on 0333 366 0103. From there Petrol in Diesel takes over, across Carcroft or anywhere within South Yorkshire.
