Then set this page down for now, leave the ignition and engine off, then phone 0333 366 0103. A drain plus a full flush, carried out just where your vehicle stands around Yalding, is usually all it needs when found before the motor runs. Reading before the event? In that case what follows explains why it comes about and how to prevent it ever happening. ## Why does AdBlue in a diesel motor need its own filler? Plenty of current diesels on the roads round Yalding and Hunton carry two liquids, not one. Diesel goes to your motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Separate tanks, different fillers. Under one flap, side by side: that's the layout on many vehicles. On others, AdBlue's filler sits under the bonnet or in your boot instead. At the pump, the diesel side gets filled constantly. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and far less frequently. The mistake grows in that gap between the two. ## How AdBlue in the diesel tank happens in Yalding Three things tend to come together, and carelessness is seldom one of them. The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Vicarage Road before work, or in the car park at The George on the way home. The old car's cap is where the hand reaches — but a hire car, a new motor or a company car puts the fillers elsewhere. That is a second factor: a new vehicle. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. The same few seconds settle it, in the middle of Yalding or out in Congelow. ## Which filler is for AdBlue, and which for diesel? Whether a Yalding forecourt or a driveway out in Laddingford, take a couple of seconds on these before anything is poured in. - Where it sits can mislead; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps normally don't. - Look at the size: the smaller neck is, on plenty of cars, the AdBlue one. - The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where. - Cannot see it beside the diesel inlet? In that case look beneath the bonnet or inside the boot — the owner's manual says which. - Picking up a hire or company car, say at the car park outside the nearest station? Check with whoever drove the vehicle last before you set off, rather than once the light comes on. ## Topping up AdBlue without it reaching your diesel tank Wherever in Kent the light comes on, here is a routine for the day. - Not in a rush on the side of High Street, not on a slope, not with your motor running: park and switch off first. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Stop once the tank is topped up or the bottle runs dry; until then, tip gently using its built-in spout. - Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car. Discover during the second or third step that the bottle went in the diesel tank? That is where you stop. Don't carry on to stage five. ## AdBlue in your diesel tank already, around Yalding? The short order of things, starting with not starting your engine. Keep your ignition off as well, since on many diesels it alone runs your pump. Diluting it with extra diesel won't work, because AdBlue settles to the base instead of mixing — and that is where the fuel is pulled from. Ask the staff to help roll the vehicle clear of the petrol pump if you are at a forecourt — the the nearest petrol station, the Shell or somewhere else. At home in Yalding? Then the car stays put. Already started? Stop once it is sensible, then turn off. Leave the M20 — under 10 miles out of Yalding — at the next junction. Mileage counts — a quick hop across Yalding makes a smaller job than heading under 25 miles towards Southend-on-Sea — so tell us roughly how far it went. ## When our engineers arrive around Yalding, what takes place? The van reaches the car wherever it stopped — your own drive, beside Yalding Village Club, or by Yalding, St Peter and St Paul Church of England Voluntary Controlled Primary School. The replies settle this work and our quote, so our engineers ask what got in, roughly how much, and whether it has run. That price is given on the call, before any van leaves. The system is then cleaned thoroughly, after your tank is drained. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. Filter cleaned or, if needed, swapped; clean diesel in; then a check of the car. We don't leave until it has been fired up and is running correctly. Most jobs are finished in about half an hour after our technicians get there, as long as the engine has not run — and the pumps our technicians use are safe on a busy forecourt yet quiet at night outside a house. Nothing in advance; you settle up on the day. Afterwards, the VAT invoice and the report from the engineer are handed to you for the insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way. ## About Yalding itself Yalding is a village in Kent, situated on the River Medway at an elevation of around 20 metres.
