Caught before the engine runs, it's generally a drain and a thorough flush, done where the vehicle is around Swartha. The remainder of this page covers why it occurs and how to make sure it doesn't — handy if you're reading before it has happened. ## AdBlue in a diesel vehicle, and its separate tank Not one liquid but two: that's what plenty of modern diesels near Swartha and Cringles run, with diesel for the engine. AdBlue's own tank keeps it, and from there it goes to the 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 the boot or under the bonnet. At the petrol pump, the diesel side is topped up constantly. Rarely filled, AdBlue usually goes in out of a bottle, poured by a driver who must stop and think what cap to use. It's in that gap that the slip lives. ## AdBlue in the diesel tank around Swartha: how it takes place Rarely is it carelessness: normally three things line up. Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done quickly, before work on a driveway off Brunthwaite Lane, or on the way home in the car park outside The Kings Arms. Next, the hand goes for the cap it knew on the old motor — since a rental car, a new vehicle or a company car puts the fillers somewhere your last one did not. Lastly, the bottle fits: diesel filler or AdBlue one, it slides in as readily, and once the tip starts, no part halts it. It takes a few seconds, be it out in High Brunthwaite or bang in the centre of Swartha. ## The AdBlue filler and your diesel filler: telling them apart Whether a Swartha forecourt or a drive out in Addingham Moorside, spend a few seconds over these before anything goes in. - Where it sits misleads; the cap doesn't. AdBlue caps are often blue or carry the word "AdBlue" — diesel ones normally do not. - Plenty of vehicles fit AdBlue the smaller filler of the two. - Look inside your fuel flap: many cars have a label there saying which fuel goes where. - In the boot or under the bonnet: that is where your filler sits if it's not by the diesel cap, and the handbook says which. - Picking up a hire or company car, say at the car park outside Steeton & Silsden? Ask whoever drove the car last before leaving, not when the light goes on. ## AdBlue top-ups that never reach the diesel tank Anywhere across West Yorkshire the light comes on, here is a routine for the day. - Stop somewhere level, motor off, with time in hand — not hurried on the side of Swartha Lane. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Before you start the vehicle, shut the cap and check a second time that the diesel cap never opened off. Discover during the second or third step that AdBlue went into the wrong tank? That is where you stop. Step five is off limits. ## Already put AdBlue in your diesel tank around Swartha? Then the order of things is short. Do not start the motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Filling up with diesel will not weaken it: rather than mixing, AdBlue sinks to the base of that tank, right where the fuel is taken from. The staff at Shell, Texaco or any forecourt will normally help pushing the car clear when you ask. Leave it where it is if you're on your own driveway around Swartha. If the motor has already run, stop as soon as it is safe then switch off. Come off the M65 — under 15 miles out of Swartha — at the first junction. A short hop across Swartha is a smaller job than a run towards Bradford, under 15 miles away, so tell us about how far it went. ## What takes place when our technicians get there in Swartha Wherever your car came to rest, be it outside Silsden Primary School, near Cote Close or on your own drive, our van travels to it. Both the work and our price depend on three replies — which fluid, which quantity, and if it has run — so our technicians ask. On the call itself, you are told our quote — ahead of dispatch. Your system is then cleaned thoroughly, once the tank is drained. Not like petrol, AdBlue forms crystals and attacks some fuel-system metals, and none of that clears away by itself. That is why it matters more. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. The motor is started next and checked to make sure it runs properly, all before our technicians leave. Unrun cars mostly mean a half-hour job after arrival. The kit is fine on a busy filling station, and hushed enough for a driveway late at night. Nothing in advance; you settle up on the day. Afterwards, a VAT invoice and a report from the engineer go to you for the insurer. While we travel, take a look at your policy; plenty carry cover for misfuelling. ## About Swartha, for a moment Swartha is a locality in West Yorkshire, situated on the riverside at an elevation of 190 metres, with semi-detached housing being the predominant type of accommodation.
