In that case put this page down a moment, leave your ignition and motor off, and phone 0333 366 0103. A drain and a thorough flush, done right where the car sits in South Chailey, is normally what it needs when found before the engine runs. If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it doesn't. ## Why does AdBlue in a diesel motor need its own filler? Diesel goes to the engine — yet many modern diesels seen round South Chailey and Godleys Green carry a second fluid as well. Its own tank holds it, and from there it is sent to your exhaust, where spraying treats the gas. Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the pump, the diesel side is topped up constantly. Rarely topped up, AdBlue usually goes in from a bottle, poured by someone who must stop and think which cap to use. The mistake grows in the gap between the two. ## South Chailey: how AdBlue in the diesel tank happens Rarely is it carelessness: normally three things line up. Haste follows from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Brickyard Lane, or on the way home in the car park at the pub in the village. The old car's cap is where the hand goes — yet a rental car, a new car or a company car puts the fillers elsewhere. That is a second factor: a strange car. A spouted bottle meets no obstacle at a diesel filler any more than at an AdBlue one. And so the tip, once started, carries on. It's a few seconds, be it in South Street or bang in the centre of South Chailey. ## The AdBlue filler and the diesel filler: telling them apart Check these first, at a forecourt around South Chailey or a drive over in East Chiltington. A few seconds, no more. - Check the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually aren't. - Check the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one. - Open the filler flap and check for a label — many cars show what belongs in which filler just there. - Can't see it beside your diesel filler? Then look beneath the bonnet or inside your boot — the handbook says which. - The previous driver will know. Ask when you pick up a hire car or fleet car — at Plumpton's car park, say — not when the light comes on. ## How to top up without AdBlue in your diesel tank Wherever across East Sussex the light comes on, this is a routine for the day. - Pull in somewhere level, motor off, with time in hand — not rushing on the side of Mill Lane. - Locate the AdBlue filler, check the cap, and speak the name "AdBlue" out loud while unscrewing it. It sounds silly. It does the trick. - The two under one flap? Then confirm the cap on your diesel side stays shut ahead of raising the bottle. - Gently is best, through the bottle's own spout, till it is full or the bottle is empty. - Only then, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you have already poured into your diesel side. Don't go on to stage five. ## Already put AdBlue in your diesel tank around South Chailey? Then the order of things is short. Don't start the engine. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Diluting it with more diesel won't work, because AdBlue settles to the base rather than mixing — and that is where your fuel is drawn from. Ask the attendants to help roll your car clear of the pump if you're on a forecourt — the Shell, the Offham Garage & Store or somewhere else. Leave it where it is if you are on your own drive in South Chailey. If the motor has already run, stop as soon as it is safe and switch off. The next exit means where to come off when you're on the M23, under 15 miles from South Chailey. Mileage counts — a short hop across South Chailey makes a smaller job than driving under 10 miles towards Brighton and Hove — so say roughly how far it went. ## When we turn up in South Chailey, what occurs? Outside Chailey St Peter's Church of England Primary School, near Chailey Free Church or on your own driveway: wherever the car has stopped, we come to it. Both the work and our price depend on three answers — which liquid, which quantity, and whether it's run — so our engineers ask. No one heads out until you've heard our price over the phone. Then your tank is drained and the system cleaned thoroughly. Not like petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of that clears away by itself. Hence it counts more. A test is last: before that, clean diesel is added, and your filter is cleaned or changed as needed. Next our engineers fire it up and confirm it runs properly before leaving. Unrun cars usually need a half-hour visit after arrival. The equipment is fine on a busy filling station, and hushed enough for a driveway late at night. Nothing upfront; you settle up on the day. Afterwards, the VAT invoice and the report from the engineer are handed to you for the insurer. It is worth looking at your policy while we travel to you: misfuelling cover is included with plenty of policies. ## About South Chailey, briefly South Chailey is a small village in East Sussex, situated inland at an elevation of 46 metres, approximately 9.6 miles north of Brighton and Hove.
