--- title: AdBlue in a Diesel Tank Crick?

Don't Start It AdBlue in your diesel tank? Then leave the engine off — and your ignition too. Water with urea mixed in it: that is AdBlue. Being water-based, it won't burn and never combines with diesel; damage only starts when the pump starts pulling it. Caught before the motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is in Crick. Phone 0333 366 0103 before you do anything else. ## What to do straight away, Crick: AdBlue in the diesel tank Do: - Keys out — then nobody can switch anything on. - Put your hazards on if you're at all close to moving traffic. - Keep the receipt or the empty bottle, and so you can tell us what went in and about how much. - Our van finds you quickest with a postcode starting NN6 7, or simply the name of a street close by, and so phone from the car. Don't: - Shifting the vehicle just a few yards is no reason to fire up your motor. - Switching your key to ignition by itself starts your pump going on plenty of diesels. Avoid it. - No more fuel on top. The AdBlue won't mix, so it is wasted. - Do not drive the vehicle anywhere, not even a short distance down The Marsh. - Emptying the tank yourself by the road is not worth trying. On a forecourt around Crick, whether it's the EG On the Move or another one, ask the attendants to help you roll your car away from the petrol pump. At your own driveway, don't move it at all. ## What does AdBlue do in a diesel tank? The motor isn't what AdBlue is made for; the exhaust is. Its own tank keeps it, and from there it's sprayed into the exhaust, and there it cleans the fumes. Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump cannot take urea. It doesn't blend. Once it's tipped into the tank, AdBlue acts nothing like diesel. It is heavier than diesel, and so it sinks and collects at the bottom of the tank, which is where the pickup pulls 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 Barby Nortoft 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 pulled it in. From there it causes two kinds of harm. Crystals and corrosion. As the water dries, it leaves urea that hardens in filters and narrow passages; and, since it eats at some metals, each part it reaches suffers for as long as it stays in there. Lines holding AdBlue spell damage by morning for a car sitting around Crick. Only in that tank, it stays stable. Diesel lubricates the injection pump and every injector as it flows; water gives no lubrication, and that is a second kind of damage. ## AdBlue in a diesel: why it is frequently worse than petrol Top up a diesel with petrol by mistake over at the BP, and the problem is diluted fuel. No harm comes while it stays put, mixed into the diesel — only when the motor works on it. AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. Since it does not burn, running it through isn't an option. Nor can it be watered down, since it separates again — and the next fill will not clear away crystals or corrosion. So the flush counts more with AdBlue, and turning your key "to see", in the heart of Crick or out in Winwick, does more harm than almost any other slip. With AdBlue, the good news is no separate from petrol. If your engine has not run, the AdBlue is still inside that tank, and that tank is the quickest part of a fuel system to clear, wherever around Northamptonshire the vehicle is sitting. ## How AdBlue ends up in a diesel tank in Crick It is not deliberate. Many vehicles keep the AdBlue cap alongside the diesel one, occasionally under a single flap, and muddling them up is easy after dark. It usually occurs outside the house, from a bottle grabbed en route home, not at the forecourt. Usually, it takes place in one of a couple of familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside Crick Primary School. A driver pours the container in at home, just off Main Road, as the day ends. Else, in dim light by The Red Lion, the car is topped up by someone opening that flap the first time. The least known vehicles see it the most — rentals, new ones, company ones, and the spare vehicle of a home with one of each fuel types. Wherever you are in Crick or the rest of Northamptonshire, it's the same mistake and the same first answer: leave the vehicle off. ## Already started the motor with AdBlue in your diesel tank in Crick? Then the tank is no longer where the AdBlue is. It has been drawn through the filter and the fuel lines, and if your motor ran for any time, it has reached the high-pressure pump and your injectors. Watch for rough running, smoke, falling power, lights on your dash, or a stall — coming back from Crick Sports Ground, perhaps, or midway across Crick. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. Each start pulls more of it through. Leave the M1, under a mile from Crick, at the first junction and stop somewhere safe, not driving on. Each mile carries the AdBlue deeper into your system. That is why crossing Crick to park near Crick United Reformed Church and a drive of under 25 miles towards Coventry are such different jobs. Let us know roughly how far it had come. We do all of the rinsing where the vehicle has ended up, and once the motor has run there is more of it. Long-term damage is very rare when it's noticed soon. ## Crick: how AdBlue is drained from a diesel The car remains put, whether that's a road near St. Margaret's Parish Church, a drive, a lay-by or a forecourt around Crick, and our van comes to it. Which fluid went in, about how much, plus if the engine has been run: our engineers ask first, since those shape the job. Then your tank is emptied where the vehicle waits, so the tainted fuel and the AdBlue come out together. Residue from AdBlue won't wash out by itself, and so the fuel system gets a careful flush, which counts much more with urea than for petrol. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. About half an hour once we arrive is typical for most jobs where the motor has not run. Low-noise enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof. Bleeding your system with fresh diesel comes at the end. Starting it comes next, and then you set off from where the vehicle is parked, by Long Buckby or on a driveway in Crick. Our engineers make sure it runs correctly on new diesel before leaving. The entire job is done where your car is, so it never needs to be taken to a workshop. The insurer is likely to want an engineer's report and your VAT invoice — each handed over once this job is done. ## About Crick and where it is Crick is a village situated on the banks of the River Avon in Northamptonshire, with a mix of rural and riverside scenery. Crick sits at an elevation of around 135 metres, close to the nearby villages of Yelvertoft and Kilsby. Crick has a population of approximately 1820 people, predominantly living in detached houses. Crick is located near the city of Coventry, about 16 miles away, and is around 72 miles northwest of London. ## AdBlue drains across Crick and Northamptonshire Our vans that answer AdBlue calls around Crick also cover the places round it, Yelvertoft, Emery Row and Kilsby among them, and most of Northamptonshire beyond, across the NN postcode area. Phone and ask rather than guess when you're by a county line, or somewhere awkward to pin down. A mobile service suits Crick, a village: there's no need to bring the vehicle to us, since our technicians drain it on the spot, in a driveway, a side street, a car park or a forecourt. ## What does AdBlue in a diesel tank cost to sort out around Crick? Each job differs, and so no fixed price is honest. The price moves first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that got in. After that it rests on where the car is and whether a van can reach it safely, which is simpler on an open drive than in a tight spot behind Crick Village Hall. For that in mind, each call from Crick opens by asking the identical trio — which fluid got in, what quantity, whether it ran — before any quote. Given them, a range shrinks to one firm number. Before anyone sets off, you hear the quote on the phone. And you pay on the day, card or by phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way. ## Beside your car around Crick, right now? Right now, the most helpful thing to do with the car is to leave it. Keys out; motor and ignition off. Petrol in Diesel handles the rest, in Crick or wherever within Northamptonshire, after you ring 0333 366 0103 to say it's AdBlue, roughly what quantity, and whether the engine ran.
