Leave It Off With AdBlue in the diesel tank, your ignition remains off and so does the engine. Urea dissolved in water is what AdBlue is. As it is water-based, it will not ignite and won't blend with diesel; damage just starts once your pump starts drawing it. A drain and a thorough flush, done where your car is in Brockmoor, is normally what AdBlue in a diesel tank takes — if it's caught before your engine has run. Before you do anything else, phone 0333 366 0103. ## Those opening minutes: AdBlue in your diesel tank around Brockmoor Do: - Take your keys out, and so no one switches your ignition on. - If you're at all close to moving traffic, put the hazard lights on. - So you can give us which fluid it was and about how much, keep the receipt or the empty bottle. - Tell us a postcode starting DY5 3, or whichever street lies closest, and the van finds you directly — so call from wherever you stand. Things not to do: - No starting your motor — not briefly, not to reposition your car. - Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump. - AdBlue does not dilute in diesel — it separates out — so adding more diesel won't weaken it. - Even a short distance down Wallows Road is too far to drive the car. - By the road, don't try emptying it on your own. On a forecourt in Brockmoor, whether it is the JET or another one, ask the staff to help you roll your car clear of the pump. Stopped on your own driveway? Then it remains exactly as it is. ## AdBlue in a diesel tank: what it does Meant for the exhaust, AdBlue has no place in your motor. Kept in a separate tank, it is injected into the exhaust stream to treat the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it. It doesn't blend. After it is poured into a tank of diesel, AdBlue behaves not at all like diesel. It sinks, because it's heavier than diesel, and pools down where the intake draws its supply from. A car topped up on a drive in Woodside yesterday evening and left unstarted is the simple one. No pump has pulled the AdBlue up yet — but once your engine runs, that is what is pulled first, directly from the bottom of your tank. From there it causes two kinds of harm. What remains when the water evaporates is urea, which forms crystals: they lodge in narrow channels and block filters. Worse, it attacks certain metals in the fuel system, and carries on till it is cleared out. Where the AdBlue is in the lines, leaving it overnight around Brockmoor makes things worse. Inside the tank alone, time does nothing. The water in it does damage of its own: the high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing. ## Why is AdBlue in a diesel frequently the bigger fault? Fill a diesel with petrol in error at the Asda, and the issue is thinned fuel. Mixed through your diesel and left still, it's no threat for now; using your motor is the damage. AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. It doesn't burn, and so it cannot simply be run through. It doesn't stay mixed, and so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than almost anywhere else, whether the car is in Holly Hall or the middle of Brockmoor. As with petrol, there's good news. Anywhere in West Midlands your car has stopped, an unrun engine leaves the AdBlue yet inside the tank: the easiest part of a fuel system to empty. ## Brockmoor: how AdBlue ends up in a diesel tank It's not on purpose. Plenty of cars have the AdBlue cap alongside the diesel one, now and then behind a single flap, and muddling them up is simple in poor light. It mostly occurs outside the house, from a container grabbed en route home, rather than at the filling station. A few familiar ways cover most cases. Hurrying, outside Brockmoor Primary School, after a warning lamp flashed on during the school run, a parent refills the car. A bottle is poured in at the end of the day on a drive just off Pensnett Road. Or the vehicle is topped up in the car park outside The Blue Brick, in poor light, by somebody who has never opened that flap before. Rented cars, brand-new vehicles, fleet vehicles, or the spare car in a family with one of each: the least known cars see it most. Wherever you are in Brockmoor or the rest of West Midlands, it is the same error and the same first answer: leave it off. ## Brockmoor: started your engine with AdBlue in your diesel tank? In that case, the AdBlue is no longer in your tank. With any running time, it travels to the injection pump and every injector, having passed through the filter and pipework. Perhaps returning from Black Country Millennium Forest, or part way across Brockmoor, the motor might run rough, smoke, drop power, light up your dash or cut out. No starting it again to test: stop when it is safe, then turn everything off. Every start pulls more of it through. If you were on the M5, under 5 miles from Brockmoor, come off at the next exit and stop somewhere sensible rather than pressing on. A quick hop across Brockmoor to the car park by Brockmoor Community Centre is one matter; driving towards Wolverhampton, under 10 miles away, is another, since each mile carries the AdBlue deeper in. So mileage matters. Roughly how far it had come is worth telling us. Wherever your car came to a stop is where all of it gets done, even with more to flush after your engine has been run. Very seldom does it leave permanent damage if it's noticed early. ## Brockmoor: how AdBlue is cleared from a diesel Our engineers come to the car, wherever it has stopped around Brockmoor: a side street close to David Lloyd Clubs, a drive, a lay-by or a forecourt. Before anything else our engineers ask what was put in, roughly how much, and whether your motor has run, since those answers settle this work. The polluted diesel and the urea leave as one when that tank is emptied, right there. Residue from AdBlue will not flush out unaided, and so the whole system gets a careful flush, which matters much more here than for petrol. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Most of these jobs are a half-hour job once we turn up, provided the motor has not run. Low-noise enough to use outside a house at night, and fine on a busy forecourt, our pumps are explosion-proof. Lastly, the fuel system is bled with clean diesel. You set off as soon as our engineers have started the car, and it makes no difference whether the car is on a drive around Brockmoor or in a bay at Lye. The test before we leave is that it runs properly on new diesel. We do it all wherever the car has ended up, and it never has to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come afterwards. ## About Brockmoor and where it is Brockmoor is a suburban area situated near the lakeside in the West Midlands, with an elevation of around 121 metres.

If you are close to a border, or somewhere hard to describe, ring and ask instead of assuming. No towing is needed. In Brockmoor, a residential suburb, a van that comes to you fits: the vehicle is drained on the spot, be it on a drive, a residential street, a parking area or a filling station. ## AdBlue in a diesel tank around Brockmoor: the cost of fixing it There's no honest single price, since the jobs aren't the same. What shifts the price is, first of all, whether the engine has been running and for how long; then how much AdBlue was put in; and finally 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 St John's Church Brockmoor. That's why each call from Brockmoor starts with the same three queries, asked before giving a figure, not after: what was put in, how much, and whether it has run. With them, a range shrinks to one firm figure. The price is given on the call, before a van sets off; settling up happens on the day, by card or over the phone, and nothing upfront. Misfuelling cover comes with plenty of insurance policies, so it is worth looking at yours before the van arrives. ## Beside the vehicle in Brockmoor, right now? In that case, touch nothing — that's the best step available. Keys out; engine and ignition off. Say it's AdBlue, about what quantity, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel handles it, in Brockmoor or anywhere within West Midlands.
