Leave the motor and ignition off and phone 0333 366 0103 now — reading can wait if AdBlue is already in your diesel tank. In Woolston, catching it before your motor runs usually means draining and a full flush on the spot. Not happened yet? Further down, the rest of the page explains the why it occurs and the ways to prevent it for good. ## AdBlue in a diesel motor: two tanks, two fillers Diesel goes to your motor — yet plenty of newer diesels seen around Woolston and Martinscroft carry another fluid as well. Its own tank holds it, and from there it goes to your exhaust, where spraying cleans the fumes. Each tank has its own filler. Some cars put the AdBlue filler in the boot or under the bonnet; plenty more have both together under one flap. At the petrol pump, your diesel side is topped up constantly. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less frequently. It's in the gap that the error lives. ## How does AdBlue in the diesel tank take place in Woolston? Rarely is it carelessness: usually three things line up. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Hillock Lane before work, or in the car park at Rope & Anchor on the way home. Then, your hand goes for the cap it would have used on the old vehicle — since a hire car, a new car or a company car places the fillers where your last one didn't. A spout-topped bottle meets no obstacle at a diesel filler any more than at an AdBlue one. And so the pour, once begun, keeps on. Grange or the middle of Woolston: it is the same few seconds either way. ## How to tell the AdBlue filler from the diesel one Be it a Woolston forecourt or a driveway out in Padgate, spend a couple of seconds over these before any goes in. - Position misleads; the cap doesn't. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps normally don't. - Look at the size: the smaller filler neck is, on many vehicles, the AdBlue one. - Lift the filler flap and check for a label — many motors show what goes in each filler just there. - The handbook says which it is when your filler isn't next to the diesel cap: the boot, or under the bonnet. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Birchwood. ## How to top up without AdBlue in your diesel tank Wherever across Cheshire the light comes on, this is a routine for the day. - Stop on level, motor off, with time in hand — not hurried on the side of Epping Drive. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - The two under a single flap? Then make sure the lid on your diesel filler is still shut ahead of raising the bottle. - Gently does it, through the bottle's own spout, until it is full or the bottle runs out. - Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the vehicle. Discover at the second or third step that the bottle went in the wrong filler? That's where you stop. Never go on to step five. ## Put AdBlue in the diesel tank in Woolston already? Brief list, then. Top of that: the engine stays off. On many diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is pulled from. If you're on a forecourt, whether it is the EG On the Move or the Asda, ask the staff to help push the car away from the pump. Your own driveway around Woolston is the place it stays. If the engine has already run, stop as soon as it is safe and switch off. Woolston lies under a mile from the M6; on it, take the first junction. Tell us roughly how far it went: a run towards Salford, under 15 miles away, is a bigger job than a short hop across Woolston. ## What occurs when we get there around Woolston Our engineers come to your car wherever it has stopped, whether that is outside Woolston CofE Aided Primary School, close to Church of the Ascension or on your own driveway. Those replies determine the work and the price, so our engineers ask what got in, about how much, and whether it's run. No one sets off before you have had our price by phone. The system is then flushed thoroughly, after the tank is cleared. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. We do not leave until it has been started and is running properly. If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is part of many insurance policies — so use the wait to look at yours. ## About Woolston Woolston is a suburban area in Cheshire, situated on the riverside with an elevation of 16 metres.
