Around Shaw Heath, catching it before your engine runs normally means a drain and a thorough flush on the spot. The rest of this page explains why it takes place and how to ensure it doesn't — handy if you are reading before it has happened. ## AdBlue in a diesel vehicle: two tanks, two fillers Diesel feeds your engine — yet many current diesels seen around Shaw Heath and Edgeley hold another liquid as well. The exhaust, not your engine, is where AdBlue goes: dosed into the fumes to clean them, from a separate tank. There's a filler for every tank. Many of vehicles share a single flap for the two, while others put the AdBlue filler to the boot or under the bonnet. Diesel gets filled on each filling station visit, week in, week out. Rarely topped up, AdBlue normally goes in from a bottle, tipped by someone who has to stop and think what filler it needs. The mistake grows in the gap between them. ## How does AdBlue in the diesel tank happen around Shaw Heath? Three things tend to come together, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low your car 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 drive off Shaw Heath before work, or in the car park at The Plough on the way home. Then the car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand hits for the cap it would have used on the old one. Nothing halts the tip once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, be it out in Cale Green or bang in the centre of Shaw Heath. ## How to tell the AdBlue filler from the diesel one Check these first, at a forecourt in Shaw Heath or a driveway over in Stockport. A few seconds, that's all. - Read the cap instead of going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel caps normally aren't. - Check the size: the smaller filler neck is, on many cars, the AdBlue one. - Look inside your fuel flap: many motors carry a label there saying which fuel goes where. - In your boot or under the bonnet: that's where the filler is if it is not by the diesel cap, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at Stockport. ## Topping up AdBlue without it reaching your diesel tank A routine for the day the light comes on, wherever across Greater Manchester that is. - Not in a rush on the side of Broadhurst Street, not on a slope, not with your engine running: park then switch off properly. - Find the AdBlue filler, check the cap, and say the word "AdBlue" out loud as you unscrew it. It sounds daft. It does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on. - Stop when that tank fills or the bottle runs dry; before that, pour slowly using the built-in spout. - Close the cap, then check once more — making sure your diesel filler stayed shut the whole time. Only then, start the vehicle. Discover at the second or third step that the bottle went in the diesel filler? That's where you stop. Stage five is off limits. ## AdBlue in the diesel tank already, in Shaw Heath? Then the order of things is short. Do not start your engine. Keep the ignition off too, since on plenty of diesels switching it on by itself runs the pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is sucked from. At a forecourt — the nearest petrol station, Esso or another — the staff will normally help roll your car clear, when you ask. Leave it where it is if you're on your own driveway in Shaw Heath. Stop as soon as it is safe and switch off, if your motor has already run. Shaw Heath sits under a mile from the M60; on it, take the next junction. Roughly how far did it go? Hopping across Shaw Heath is less a job than a trip of under 10 miles to Manchester, so say. ## What happens when our engineers turn up around Shaw Heath Wherever the car came to rest, be it by Cale Green Primary School, near Kimberley Street Community Centre or at home, the van comes to it. What liquid was put in, the amount, and whether it ran: our engineers ask because those replies set both work and price. No one heads out before you have heard the price over the phone. Your system is then purged thoroughly, after the tank is cleared. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of it washes away by itself. Hence it matters more. Filter cleaned or, where needed, swapped; clean diesel in; and then a test of your car. We don't go until it has been fired up and is running smoothly. Unstarted cars usually mean a half-hour visit after the moment we arrive. The equipment is fine on a busy forecourt, and hushed enough for a residential street late at night. Paying happens on the day, not upfront, and you are given the documents your insurer asks for: an engineer's report and a VAT invoice. It's worth looking at your policy as the van travels to you: misfuelling cover is included with many policies. ## About Shaw Heath, briefly Shaw Heath is a suburban area in Greater Manchester, situated near several lakes and waterways at an elevation of around 79 metres.
