Caught before the motor runs, it is normally a drain and a thorough flush, done where the vehicle is in Stoke-on-Trent. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not. ## Why does AdBlue in a diesel car need its own filler? Not one fluid but two: that's what plenty of newer diesels near Stoke-on-Trent and Northwood run, with diesel feeding the engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Separate tanks, different fillers. Under one flap, side by side: that is the arrangement on a lot of cars. On others, AdBlue's filler sits under the bonnet or in the boot instead. Diesel gets filled on every filling station call-out, week in, week out. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less frequently. That gap is where the error lives. ## How does AdBlue in your diesel tank happen in Stoke-on-Trent? Carelessness rarely causes it. What does is three things coming up together. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Potteries Way before work, or in the car park outside The Coachmakers Arms on the way home. Next, the hand goes for the cap it knew on the old motor — because a hire car, a new motor or a company car places the fillers somewhere your last one didn't. Lastly, the bottle goes in: diesel filler or AdBlue filler, it slides in as readily, and once the tip starts, nothing stops it. Whether it happens in Hanley or the middle of Stoke-on-Trent, it is the same few seconds. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in Shelton or a forecourt around Stoke-on-Trent. - Position misleads; the cap does not. AdBlue ones are often blue or bear the word "AdBlue" — diesel caps normally don't. - Look at the size: the smaller neck is, on plenty of motors, the AdBlue one. - Look inside the fuel flap: many cars carry a label there saying which fuel goes where. - The handbook shows where it lives when your filler isn't next to the diesel cap: the boot, or under the bonnet. - Picking up a hire or company car, perhaps at the car park at the nearest station? Check with the person who drove the car last before you set off, rather than when the light goes on. ## Topping up AdBlue without it reaching the diesel tank A routine for the day the light comes on, wherever in Staffordshire that is. - Not in a rush on the side of Victora Roundabout, not on a slope, not with your motor running: park and switch off properly. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the vehicle on. - Finish when the tank is topped up or the bottle is empty; before that, tip gently through its own spout. - Before starting the car, close the cap and look a second time that your diesel cap never came off. Discover during the second or third stage that the bottle went in the diesel filler? That's where you stop. Never carry on to step five. ## AdBlue in the diesel tank already, in Stoke-on-Trent? Don't start the motor: that's how the short order of things begins. Keep the ignition off as well, since on many diesels switching it on alone starts your pump. Filling up with diesel will not weaken it: rather than mixing, AdBlue sinks to the base of the tank, just where the fuel is drawn from. If you're on a forecourt, whether it's the Gulf or the Tesco, ask the attendants to help roll the vehicle clear of the petrol pump. Your own driveway around Stoke-on-Trent is the place it stays. If the engine has already run, stop as soon as it is safe and switch off. Stoke-on-Trent sits under 5 miles from the M6; on it, use the next junction. Tell us roughly how far it went: a run towards Lichfield, under 50 miles away, is a bigger job than a short hop across Stoke-on-Trent. ## What takes place when our engineers turn up in Stoke-on-Trent We come to your car wherever it has stopped, whether that's outside Waterside Primary School, close to Sacred Heart Catholic Church or on your own drive. Both the work and our quote rest on three replies — which liquid, what quantity, and whether it's run — so our technicians ask. You hear that price by phone, before anybody sets off. Your system is then rinsed thoroughly, after that tank is drained. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither clears out unaided. Hence it counts more. A test comes last: before that, fresh diesel goes in, and your filter is cleaned or changed as needed. Before we leave, our technicians fire it up and check that it's running smoothly. Using pumps fine on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run take about half an hour after our engineers are there. 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 while we travel to you: misfuelling cover is included with many policies. ## About Stoke-on-Trent and where it is Stoke-on-Trent is a city situated in Staffordshire, England, with a riverside setting that adds to its charm.
