A drain and a thorough flush, carried out just where the vehicle stands around Horwich End, is usually what it needs if caught before the engine runs. The remainder of this page explains why it takes place and how to ensure it does not — handy if you are reading ahead of time. ## AdBlue in a diesel motor, and its separate tank Many current diesels on the roads around Horwich End and Taxal carry two liquids, not one. Diesel goes to the motor. Stored in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it. Each tank has its own filler. Other cars put the AdBlue filler in your boot or under the bonnet; plenty of others have the two together under one flap. At the petrol pump, the diesel side is topped up all the time. The AdBlue side is filled far less frequently, normally from a bottle, and usually by someone who has to stop and think where it goes. It's in the gap that the slip happens. ## How AdBlue in the diesel tank takes place around Horwich End Three things tend to line up, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Cotton Close before work, or in the car park at Drum and Monkey on the way home. Then the car is strange. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one. A spout-topped bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the pour, once started, carries on. Whether it takes place in Over Leigh or the middle of Horwich End, it's the same few seconds. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Whaley Bridge or a forecourt around Horwich End, check these. They take a couple of seconds. - Position can mislead; the cap doesn't. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel caps usually do not. - Plenty of vehicles fit AdBlue the smaller filler of the two. - The flap. Look inside your fuel flap for a label. Many vehicles say there which fuel goes where. - The handbook says which it is if your filler isn't next to the diesel cap: your boot, or under the bonnet. - Whoever had it before will know. Check as you pick up a rental or company car — at Whaley Bridge's car park, perhaps — not once the warning appears. ## AdBlue top-ups that never reach the diesel tank A routine for the day the light comes on, wherever across Derbyshire that is. - Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Chapel Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - The diesel cap remains on. Where both sit under a flap, confirm it is shut before lifting the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Only then, start your car: close the cap, check again, and make sure the diesel cap was never opened. If at step two or three you find you have already poured into your diesel side, stop there. Stage five is off limits. ## Horwich End: already put AdBlue in your diesel tank? Then the order of things is short. Do not start the motor. Do not switch your ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is drawn from — so do not top up with diesel to thin it. Ask the attendants to help roll the vehicle clear of the petrol pump if you are at a forecourt — the Tesco, the Morrisons or anywhere else. At home around Horwich End?

We come to the car wherever it has stopped, whether that is outside Taxal and Fernilee CofE Primary School, close to 1st Taxal Scout Group or on your own driveway. What liquid went in, the quantity, and if it ran: our engineers ask since the answers set both work and price. No one sets off until you've had our price by phone. The fuel system is then purged thoroughly, after your tank is emptied. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither washes out by itself. That is why it counts more. Once your filter has been flushed — or renewed, where needed — clean diesel goes in, and finally your vehicle gets tested. We don't go until it has been fired up and is running correctly. Unstarted cars mostly mean a half-hour visit after arrival. The equipment is safe on a live forecourt, and quiet enough for a driveway late at night. Nothing in advance; you settle up on the day. Afterwards, the VAT invoice and the report from the engineer are handed to you for your insurer. It's worth looking at your insurance while we travel to you: misfuelling cover is included with plenty of policies. ## About Horwich End and where it is Horwich End is a suburban area in Derbyshire, situated on the riverside at an elevation of 183 metres, with terraced housing being the predominant type of accommodation.
