--- title: What Now? AdBlue in a Diesel Tank Toothill canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/toothill-hampshire/ location: Toothill county: Hampshire latitude: 50.963650 longitude: -1.465760 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # Toothill: AdBlue in the Diesel Tank? Find Your Situation Everything turns on one detail: whether the engine has started since the AdBlue went in — far more than anything else. If it hasn't, keep it that way, whether the vehicle is in Toothill itself or out in Lee. Switch nothing on, phone 0333 366 0103, and count on a thorough flush after a drain, carried out just where your car stands around Toothill. Already run? Stop once you safely can, then switch it off. Stage one stays unchanged, even if the job grows. Find the situation below that matches yours, wherever around Hampshire it happened. ## On a Toothill forecourt with AdBlue in a diesel You're at the petrol 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, maybe at the Kingslake Cars, perhaps somewhere else in Toothill. Meaning? Spotting it on the forecourt is as good as it can be. Just the tank has AdBlue; not one part past it has drawn it in. Next: avoid the temptation to start it only to free up the pump. Ring us from the forecourt after your vehicle is in a space — the staff will help roll it — and save the receipt. If it can't be shifted, it can be drained at the petrol pump: the equipment is explosion-proof and safe on a working forecourt. ## AdBlue in your diesel tank at home around Toothill For days the dashboard had been warning you. Only by the recycling, the empty bottle in your hand, did you look back at the cap you had used at the driveway. Drives close to Toothill Road get it as much as any other street. What it means: if you have not driven since, this is nearly as good as the forecourt. Diesel and AdBlue keep separate: the AdBlue drops to the base of the tank and remains put, however long it waits. Keep the keys in the house tonight — or a person might take it off first thing — and phone us. Out in Rownhams or here around Toothill, the draining is done on your driveway. The pumping kit runs quiet enough that it won't wake the neighbours at night. ## Drove off with AdBlue in a diesel in Toothill? You filled up, set off, and a mile or two later the engine began to run roughly, smoke, lose power or light up the dashboard. Upper Toothill Road, perhaps, or the way to Southampton — a run of under 5 miles. In short: the AdBlue has been sucked through the system. Past the fuel filter, along the pipework, and — the more the mileage — deeper into the injection pump and every injector. It travels deeper with each extra mile driven and each restart. What to do: pull over where it's safe to do so then switch off. On the Nursling Spur Motorway, under a mile from Toothill, that means the next exit, not the services further on. Don't restart the vehicle to see if it has cleared; it will not have. Call, and say how far your car went. ## AdBlue in the wrong tank: hire, lease and company cars It is a vehicle you have had for a week. The AdBlue filler is right alongside the diesel filler, which you didn't know, because your own car either has no AdBlue or keeps it somewhere else. Anyone, wherever around Hampshire, could make it. The upshot: exactly as above, split by whether it ran, only with one added step. The owner frequently has to approve the work, under plenty of hire and company agreements. What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before our engineers arrive than after. Keep the vehicle switched off as the answer comes, whether you're waiting outside Romsey or close to Toothill Hill Fort. ## AdBlue in your diesel tank? Not sure, in Toothill At times, "I think so" is the most anyone can honestly say. A faint ammonia smell lingers around your filler, the bottle seems too light, and which cap came off is a blur. A rushed stop by the gates of Rownhams St John's Church of England Primary School, or a visit to a friend in Nursling: either fits. What it means: a little spilled round your filler does no harm to your engine. AdBlue inside your diesel tank does. You can't tell which by turning the ignition, and doing so will pull in any AdBlue that is in the tank. What to do: treat it as if it got in. Don't crank it. Inspecting a tank that proves clean beats draining one after it has been run — so ring then tell us what you noticed. ## What every AdBlue drain around Toothill has in common Whichever situation you are in, this job starts the same way. Three questions come once our engineers reach your car — on a filling station, a drive, a road beside St John's, Rownhams or the car park at the pub in the village: the fluid, the amount, and whether the motor has run. Those replies determine this work, and you get the price on the phone, before anybody heads out. Emptying your tank comes first, followed by a careful flush — more vital with urea than after petrol, because crystals and corrosion won't clear on their own, no matter how long you wait. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. If your motor has not run, most jobs take about half an hour once we are there. The final step is firing it up. Our engineers check it runs properly on fresh diesel before leaving. The whole job is done where the car is, and when it is caught quickly, permanent damage is very unusual. Paying comes that day, never upfront. For your insurer, there is a VAT invoice plus a report from the engineer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way. ## About Toothill Toothill is a small hamlet in Hampshire, situated inland at an elevation of 51 metres, approximately 4.9 miles from Southampton.
