--- title: What Now? AdBlue in a Diesel Tank Highgate canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/highgate-south-yorkshire/ location: Highgate county: South Yorkshire latitude: 53.532540 longitude: -1.320050 service: AdBlue in a Diesel Tank updated: 2026-10-21 --- # Highgate: AdBlue in the Diesel Tank? Find Your Situation All of that turns on one detail: whether the engine has been run after the AdBlue was added — more than anything else. Not run yet? Then leave it like that, wherever your vehicle is — Highgate or Bolton upon Dearne. Usually this means emptying and properly rinsing it on the spot in Highgate — so keep your key and engine off then phone 0333 366 0103. If it has run, stop as soon as it is safe and switch off. Step one stays unchanged, even if the job is bigger. Match what happened to a situation from the ones below, anywhere around South Yorkshire you happen to be. ## Highgate forecourt: AdBlue in a diesel at the pump You are at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Maybe you're at the BP, possibly at the Texaco, perhaps somewhere else around Highgate. The upshot: of every spot to notice, the forecourt is the best. Only that tank holds AdBlue; not one part past it has taken any in. Do this: keep out of the car, however much the pump wants freeing. Have the staff to help pushing it into a bay, save the bottle, then phone us from there. If it can't be moved, it can be emptied at the pump: the equipment is explosion-proof and safe on a busy forecourt. ## AdBlue in the diesel tank at home around Highgate For days the dashboard had been warning you. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look once more at the cap. Right off Hawthorne Croft is no less likely from any other place. What it means: if you haven't driven since, this is nearly as good as the forecourt. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that. What to do: leave your keys inside the house so no one moves the car in the morning. Then call. Out in Goldthorpe or here around Highgate, the draining happens on your drive. The pumps are quiet enough to use outside a house after dark. ## Highgate: set off with AdBlue in a diesel? A mile or two after topping up, the engine began misbehaving: rough running, smoke, less power, warnings on the dash. Holly Grove, say, or the way to Doncaster — a trip of under 10 miles. What it means: the fuel system has drawn the AdBlue in. Past your filter, along the lines, and — the further the distance — deeper into the high-pressure pump and every injector. Each restart, like every mile, pushes it deeper. What to do: pull over where it is safe to do so then switch off. Leave by the first junction — not the services further along — if you're on the A1(M), under 5 miles from Highgate. Restarting it to check gets nothing — AdBlue doesn't clear on its own. Roughly how far did it go? Say so when you call. ## Hire, lease or company car with AdBlue in the wrong tank It's a motor you have had for a week. Your own car either has no AdBlue or puts it somewhere different, so no one told you the AdBlue inlet sits just beside your diesel. Any driver, anywhere around South Yorkshire, might make the same. What it means: the same as the situations above, depending on whether it has run, with one more stage. The owner frequently needs to sign off the work, under plenty of hire and company agreements. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before our engineers arrive than after. Keep the vehicle switched off as the reply comes, whether you are parked at Goldthorpe or near Highgate Greyhound Stadium. ## Highgate: unsure if it was AdBlue in the diesel tank? "I think so" is sometimes the most honest answer there is. The bottle is lighter than it should be, there's a faint smell of ammonia about your filler, and you can't remember which cap you took off. Possibly it happened in a hurry at the school gates at Highgate Primary Academy, or on a friend's drive in Thurnscoe East. What it means: a little spilled about the filler does no harm to your engine. If it's inside the diesel tank, though, it does. If there is AdBlue in your tank, starting your car would pull it in, and it would not tell you which either. Next: assume it got in, and keep the engine off. Tell us what you noticed on your phone. A clear tank checked counts as a happier result than a run one emptied. ## The common ground in every Highgate AdBlue drain Every case gets the same start to the job. Our engineers come to your car, whether it is on a forecourt, a driveway, the car park at The New Bank or a side street close to Dearne Family Centre, and ask three things: what was put in, about how much, and whether your motor has been run. Answers set the work; the price follows by phone while nobody has left yet. Emptying the tank comes first, then a careful flush — more vital with urea than after petrol, because crystals and corrosion will not clear on their own, no matter how long it sits. Then comes the fuel filter — cleaned, or replaced where necessary — followed by clean diesel, and a test of your car. If the motor hasn't run, most jobs take about half an hour once we're there. Our technicians start the engine at the end. With new diesel in, it runs while our technicians confirm it's running smoothly, and then we head off. Our technicians do the entire job where your car is, and long-term damage is very unusual if it has been spotted early. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance while we're en route: misfuelling cover is included in many policies. ## About Highgate, briefly Highgate is a suburban area in South Yorkshire, situated near the banks of a river at an elevation of around 45 metres.
