AdBlue already in your diesel tank? In that case set this page aside a moment, leave your ignition and engine off, and ring 0333 366 0103. Usually, when the engine has not run, it's emptied and thoroughly flushed where your vehicle sits in Longbridge Hayes. Nothing happened yet? Further down, the page explains the why it occurs and the how to avoid it for good. ## Two fillers, two tanks: AdBlue in a diesel vehicle Diesel goes to the motor — but many newer diesels driven around Longbridge Hayes and Porthill hold another fluid as well. The exhaust, not your engine, is where AdBlue ends up: sprayed into the gas to fresh them, from a separate tank. Every tank comes with a filler of its own. Many of motors have a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet. Filling your diesel side at the pump goes on constantly. The AdBlue side is topped up far less frequently, normally from a bottle, and usually by a person who has to stop and think where it goes. It's in the gap that the slip lives. ## How AdBlue in the diesel tank takes place in Longbridge Hayes Carelessness rarely causes it. What does is three things lining up at once. Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up happens quickly, before work on a driveway off Peel Street, or heading home in the car park at The Pack Horse. The old car's cap is where the hand reaches — yet a hire car, a new vehicle or a company car keeps the fillers elsewhere. That is the second factor: an unfamiliar 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 tip once it has started. It's seconds, be it in Longport or bang in the centre of Longbridge Hayes. ## Telling the AdBlue filler from the diesel filler A couple of seconds is all these take — so run through them before you pour anything, on a drive in Dimsdale or a forecourt in Longbridge Hayes. - Blue and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position. - Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - Look inside the fuel flap: plenty of cars have a label there saying which fuel goes where. - The handbook. If your filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which. - Picking up a hire or company car, say at the car park at Longport? Ask the person who drove the car last before leaving, rather than once the light comes on. ## Keeping AdBlue out of your diesel tank when you top up A routine for the day the light comes on, wherever in Staffordshire that is. - Switch off after you park — level ground, motor stopped, and never rushed beside Longbridge Hayes Road at the roadside. - Find the AdBlue filler, read the cap, and say the name "AdBlue" out loud while unscrewing it. It seems silly. It does the trick. - Both behind one flap? So confirm the cap on your diesel side stays shut before raising the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only after that, start your car: close the cap, check once more, and make sure your diesel cap was never opened. Find at the second or third step that the bottle went in the diesel filler? That is where you stop. Skip stage five entirely. ## AdBlue in the diesel tank already, in Longbridge Hayes? Don't start your motor: that's where the short order of things begins. The fuel pump starts on plenty of diesels as soon as your ignition is switched on — so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is pulled from — so do not top up with diesel to dilute it. On a forecourt — BP, another forecourt nearby or any other — the staff will normally help push the vehicle clear, when you ask. Your own drive in Longbridge Hayes is the place it stays. If the motor has already run, stop as soon as it is safe and switch off. Longbridge Hayes sits under 5 miles from the M6; on it, use the next exit. Distance matters — a short hop across Longbridge Hayes makes a smaller job than driving under 3 miles to Stoke-on-Trent — so say about how far it went. ## Our arrival around Longbridge Hayes, and what happens next Anywhere your car has stopped, be it outside Bursley Academy, beside Sri Kanakadurkai Amman Temple or at home, the van comes to it. Our engineers ask what went in, roughly how much, and if it has run, because the answers decide the work and the price. No one heads out until you've heard our quote over the phone. After that: a drain, then a full flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush matters more with AdBlue than with petrol. After the fuel filter has been flushed — or replaced, where required — clean diesel is added, and then your vehicle is tested. The motor is started next and tested to confirm it runs correctly, all before we head off. With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs where your motor has not run need 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's worth looking at your policy as the van travels to you: misfuelling cover comes with many policies. ## About Longbridge Hayes, briefly Longbridge Hayes is a suburban area in Staffordshire, situated near the River Trent and close to the city of Stoke-on-Trent.
