In that case set this page down a moment, leave the ignition and engine off, then phone 0333 366 0103. Caught before the motor runs, it's usually a drain and a thorough flush, done where the vehicle is around Horton Kirby. Here in advance? Then the rest explains why it happens and how to stop it happening at all. ## AdBlue in a diesel vehicle, and its separate tank Plenty of newer diesels on the roads around Horton Kirby and St Margarets carry two liquids, not one. Diesel goes to the engine. AdBlue's own tank holds it, and from there it goes to the exhaust, where spraying cleans the fumes. Each tank has one filler of its own. Some cars put the AdBlue filler in the boot or under the bonnet; plenty more place the two side by side behind one flap. At the petrol pump, your diesel side is topped up all the time. A driver who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and far less commonly. Mistakes happen in the gap between the two. ## How AdBlue in the diesel tank occurs around Horton Kirby Three things tend to come together, and carelessness is seldom one of them. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Lombard Street before work, or in the car park at The Bull on the way home. Then the car is strange. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one. No part halts the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. South Darenth or the heart of Horton Kirby: it takes the same few seconds in both. ## How to tell the AdBlue filler from the diesel one Whether a Horton Kirby forecourt or a drive over in Speed Gate, take a couple of seconds over these before anything goes in. - Colour and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not where it sits. - Check the size: the smaller neck is, on many cars, the AdBlue one. - Lift the filler flap and look for a label — plenty of vehicles show what goes in each inlet right there. - Can't see it beside the diesel inlet? In that case check below the bonnet or in the boot — the owner's manual says which. - Whoever had it before knows. Ask when you collect a hire car or fleet car — at Farningham Road's car park, perhaps — not once the light comes on. ## Keeping AdBlue out of your diesel tank when you top up For the day the light comes on — wherever it is around Kent — a simple routine to use. - Not in a rush on the side of Forge Lane, not on a slope, not with the engine running: park then switch off properly. - Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud as you unscrew it. It seems silly. It does the trick. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Skip step five entirely. ## Horton Kirby: already put AdBlue in the diesel tank? Do not start your motor: that's where the short order of things begins. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. Diluting it with extra diesel won't work, since AdBlue settles to the bottom instead of mixing — and that is where your fuel is drawn from. If you're on a forecourt, whether it's the Harvest Energy or the Shell, ask the staff to help push the vehicle clear of the petrol pump. At home around Horton Kirby? So the car remains put.

The van comes to your car wherever it has come to rest — your own driveway, beside Saint Mary the Virgin, or by Horton Kirby Church of England Primary School. What fluid went in, the quantity, and whether it ran: we ask because the answers decide the work and quote. Nobody heads out before you've heard our price over the phone. The system is then cleaned thoroughly, after the tank is drained. Much more than with petrol, it counts here: the crystals build up, some metals corrode, and none of that washes out unaided, no matter how long it is left. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. The engine is started next and tested to make sure it runs correctly, all before our technicians head off. Unrun cars mostly need a half-hour visit after arrival. The kit is fine on a live filling station, and quiet enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your insurance as the van travels to you: misfuelling cover is included with many policies. ## About Horton Kirby and where it is Horton Kirby is a village in Kent, situated on the banks of the River Darent at an elevation of around 39 metres.
