--- title: AdBlue in a Diesel Tank Harlequin: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/harlequin-nottinghamshire/ location: Harlequin county: Nottinghamshire latitude: 52.948890 longitude: -1.026610 service: AdBlue in a Diesel Tank updated: 2026-10-09 --- # What Now? AdBlue in the Diesel Tank in Harlequin Everything turns on a single fact: whether the engine has been run since the AdBlue went in — more than anything else. Out in Stragglethorpe or here around Harlequin, an unstarted motor must remain unrun. Leave your engine and your ignition off and call 0333 366 0103; it's usually a drain and a thorough flush, done where the car is in Harlequin. Already run? Pull over when safe, then switch everything off. Stage one remains the same, even if the job grows. Find the situation below that matches yours, wherever in Nottinghamshire it happened. ## On a Harlequin forecourt with AdBlue in a diesel Imagine it: stood by the pump, holding the bottle, you realise the cap you opened was not the right one. Somewhere around Harlequin, then — Morrisons, Shell, or somewhere else nearby. In short: no better spot to be to discover it. The AdBlue is inside that tank and nowhere else. Nothing has pulled it in. Next: resist the urge to start it only to free up the petrol pump. Ask the attendants to help you roll the vehicle into a parking spot, keep the till receipt or the bottle, then phone us from the forecourt. Can't move the vehicle by the petrol pump? Our explosion-proof equipment keeps a busy forecourt safe, and so we can drain the car where it is. ## Harlequin, at home: AdBlue in your diesel tank The warning light had been on for days. A bottle bought at the garage, tipped in on the driveway — and it was just by the bin that the cap got a second look. Homes just off Bingham Road are hit as often as anywhere else. What it means: if you haven't driven since, this is almost as good as the forecourt. Being unable to mix, AdBlue settles low inside the tank and stays. One night parked changes none of that. Put your keys indoors tonight — or someone may drive it away at breakfast — then call us. We drain it on your driveway, whether that's in Harlequin or out in Radcliffe on Trent. Our equipment runs quiet enough that it won't wake the street at night. ## Harlequin: drove off with AdBlue in a diesel? A short way after topping up, the engine began misbehaving: rough running, smoke, less power, lights on your dash. Maybe heading for Nottingham, under 10 miles away, or simply along Morley Gardens. Meaning? Your pump has taken the AdBlue up. The high-pressure pump and every injector get it too on a longer run, once your filter and lines have it. It goes deeper with each mile covered and every restart. Pull in somewhere safe — that is the next job — then switch it off. On the M1, under 10 miles from Harlequin, that means the next junction, not the services further on. It will not have cleared, and so there is no sense starting it again to find out. Tell us know the mileage driven as you ring. ## A hire or company car with AdBlue in the wrong tank? It's a vehicle you have had for a week. On your own car, AdBlue is absent or somewhere else. On this one, its cap is just by your diesel cap — a surprise to you. Anyone, wherever in Nottinghamshire, might make it. The upshot: just as above, split by if it ran, but with one added stage. Many rental and company agreements need the owner's approval for repairs. What to do: ring the hire firm or your fleet manager first, then us. That's quicker settled before our technicians arrive than after. Leave the vehicle off while the reply comes, whether you are waiting at Radcliffe (Nottinghamshire) or close to Dave Bullas Sports Centre. ## Unsure about AdBlue in your diesel tank in Harlequin? Sometimes the honest answer is "I think so". A slight ammonia whiff hangs around the filler, the bottle seems too light, and which cap came off is a blur. Maybe it happened in a hurry at the school gates at Radcliffe-on-Trent Infant and Nursery School, or on a friend's drive in Shelford. The upshot: your motor isn't harmed by some AdBlue spilled on the filler. Once it's inside your diesel tank, though, that changes. Turning on your car won't tell you which, and if there is AdBlue in your tank it will suck it in. What to do: treat it as if it went in. Don't crank it. Tell us what you noticed on the phone. A clear tank checked counts as a happier result than an already-run one emptied. ## The common ground in every Harlequin AdBlue drain Each case gets the same opening to the job. Anywhere the vehicle is — The Radcliffe's car park, a street beside St. Anne's Catholic Church, a driveway, a forecourt — our van arrives and asks about the fluid, the amount, and if the engine has been run. Your price is given over the phone, ahead of anyone setting off, and those replies shape the job. Draining that tank comes first, followed by a full flush — more important after urea than with petrol, since crystals and corrosion won't clear on their own, no matter how long you wait. Fresh diesel goes in once the filter is cleaned or changed, and the car is finally tested. The majority of unrun vehicles are a half-hour job after the moment we turn up. Our engineers fire it up last. We confirm it runs smoothly on clean diesel before we leave. If it is spotted soon, the car very rarely has permanent damage, and the whole job takes place where it is. Paying comes that day, never upfront. For your insurer, there is a VAT invoice plus a report from the engineer. Many insurance policies cover misfuelling, and so look at yours as we head over. ## About Harlequin itself Harlequin is a locality situated in the East Midlands region of England, approximately 5.2 miles from Nottingham.
