--- title: Selborne: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/selborne-hampshire/ location: Selborne county: Hampshire latitude: 51.096170 longitude: -0.940540 service: AdBlue in a Diesel Tank updated: 2026-10-27 --- # AdBlue in the Diesel Tank in Selborne: What Now? One thing counts most once AdBlue is in a diesel tank, and that is whether the engine has run since. Not started yet? Then leave it like that, wherever your car sits — Selborne or Hartley Mauditt. Call 0333 366 0103 with your ignition and engine both off. In Selborne, such a case is typically drained and cleaned on the spot. Stop the minute it is safe then switch off, if it has been run. Step one stays the same, even though the work is bigger. Further down: the cases our engineers meet, anywhere across Hampshire. Pick the one that fits. ## On a Selborne forecourt with AdBlue in a diesel Just at this point, nozzle yet in hand, you realise that the cap you opened was the wrong one, right at the pump. Maybe you are at the Shell, possibly at the Esso, perhaps somewhere else around Selborne. Meaning? Spotting it here is the best it can be. Still inside the tank, with no fuel drawn through: that is where the AdBlue is. Next: resist the temptation to start it just to free up the petrol pump. Ask the attendants to help you roll your car into a parking bay, keep the till receipt or the bottle, then call us from the forecourt. Draining it there at the pump is fine if it cannot be moved, because the equipment is explosion-proof. ## AdBlue in the diesel tank at home around Selborne For days the dashboard had been warning you. A bottle bought at the shop, tipped in on the driveway — and it's just at the recycling that the cap caught a second look. Homes just off B3006 get hit as much as anywhere else. Put simply: if the vehicle hasn't moved since, it's almost equal to spotting it at the forecourt. Being reluctant to mix, AdBlue drops to the base inside your tank and stays. One night standing changes nothing. What to do: leave the keys inside the house so no one moves the car in the morning. Then ring. Our engineers drain the vehicle on your drive, whether that's around Selborne or out in Empshott. Our equipment works quietly enough not to disturb the neighbours at night. ## On the road around Selborne with AdBlue in a diesel You filled up, set off, and a mile or two later your engine began to run unevenly, smoke, lose power or light up the dashboard. Honey Lane, perhaps, or the route towards Winchester — a trip of under 25 miles. Meaning? The fuel pump has sucked the AdBlue in. Through the filter, along the pipework, and — the more the distance — deeper into the high-pressure pump and every injector. Every restart, like every mile, pushes it deeper. Next: pick a sensible spot, pull in, and turn your engine off. Service stations further on are too far: on the M3, under 15 miles out of Selborne, use the next junction. Starting it again to test gets nothing — AdBlue doesn't clear on its own. Phone, and say how far the vehicle was driven. ## Hire, lease or company car with AdBlue in the wrong tank A week ago, the car was new to you. Unknown to you, the AdBlue and diesel fillers sit next to each other here — unlike your own car, which has none or stores it in another spot. Wherever you are in Hampshire, every driver can slip up. In short: an extra stage on top of the situations above, which turn on whether it's run. Plenty of rental and company agreements need the owner's approval before repairs. Settling it before the van turn up is faster, and so phone the rental company or your fleet manager, then us. Leave it off as the reply comes, whether you are parked outside Alton or near Selborne Village Hall. ## Not sure it was AdBlue in your diesel tank, Selborne? "I think so" is often as honest answer there is. A slight ammonia smell lingers near the filler, the bottle feels too light, and which cap came off is hard to recall. A hurried top-up by the gates of Selborne Church of England Primary School, or a call to a friend in West Worldham: both fit. Meaning? Drips outside the filler don't reach your engine at all. If it's inside your diesel tank, though, that changes. Starting your car will not tell you which, and if there is AdBlue in your tank it will pull it in. Next: assume it got in, then leave your motor off. Phone and give what you saw: we'd rather confirm a tank free of AdBlue than empty one after the motor has run. ## Each AdBlue drain in Selborne shares these steps Whatever the case, a single start is used. Our engineers come to the car, whether it is at a forecourt, a drive, the car park at The Selborne Arms or a side street close to Gilbert White's House, and ask three things: what went in, about how much, and if your motor has run. The price is given on the call, ahead of anyone setting off, and those replies set the work. A thorough flush comes after this drain. With petrol it's standard; with AdBlue it is crucial, since deposits form and certain metals corrode, and none of that rinses out unaided. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Not started? Then about half an hour on site is most jobs. Finally, our engineers start the car. Our check that it runs properly on new diesel comes before our engineers leave. When it's caught soon, the vehicle very seldom has permanent damage, and the whole job takes place where it is. Paying comes on the day, never in advance. For your insurer, you get a VAT invoice and a report from the engineer. Many insurance policies cover misfuelling, so look at yours while the van travels. ## About Selborne itself Selborne is a small village situated in the South East of England, in the county of Hampshire, with a population of around 568 people.
