AdBlue already in the diesel tank? Then put this page aside a moment, leave the ignition and engine off, then phone 0333 366 0103. A drain plus a thorough flush, carried out right where the car stands around Banners Gate, is normally what it takes if found before your engine runs. Nothing happened yet? Below, the rest of the page covers the reasons it happens and the ways to prevent it altogether. ## Why does AdBlue in a diesel vehicle need its own filler? Plenty of current diesels on the roads round Banners Gate and Pheasey carry two liquids, not one. Diesel goes to the motor. AdBlue's own tank holds it, and from there it is sent to your exhaust, where spraying cleans the gas. Each tank has its own filler. Under one flap, side by side: that is the arrangement on many cars. On others, AdBlue's filler is beneath the bonnet or in your boot instead. Diesel goes in at every filling station call-out, again and again. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and far less frequently. The error lives in that gap. ## How does AdBlue in the diesel tank take place around Banners Gate? Three things tend to line up, and carelessness is seldom one of them. First, the warning. Low AdBlue brings a warning from the car, and running dry means limp mode — hence a rushed top-up, perhaps before work off Chester Road North, or at The Queslett on the way home after work. Next, your hand reaches for the cap it would have used on the old motor — since a hire car, a new car or a company car places the fillers somewhere your last one did not. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour after it has started. It takes seconds, be it out in Kingstanding or right in the heart of Banners Gate. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a drive in New Oscott or a forecourt in Banners Gate, check these. They take a few seconds. - Where it sits misleads; the cap doesn't. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel ones normally do not. - Check the size: the smaller neck is, on many cars, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook shows where it lives when your filler isn't next to your diesel cap: the boot, or under the bonnet. - Whoever had it before knows. Ask when you collect a rental or fleet car — from Sutton Coldfield's car park, perhaps — not once the light appears. ## How to top up without AdBlue in your diesel tank Wherever around West Midlands the light comes on, this is a routine for the day. - Switch off after you park — flat ground, engine stopped, and not rushed beside Longmore Close on the verge. - Silly as it sounds, speaking "AdBlue" out loud while you unscrew the cap works — after you've located the filler and read the cap. - The diesel cap remains on. When the two share a flap, confirm it is shut before lifting the bottle. - Gently does it, through the bottle's own spout, till it's full or the bottle runs out. - Only then, start the car: close the cap, check once more, and make sure the diesel cap was never opened. Spot at stage two or three that it's already gone into the diesel side? So stop just there. Don't carry on to step five. ## Banners Gate: already put AdBlue in your diesel tank? Brief list, then. Top of it: your engine stays unstarted. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel won't thin it: rather than mixing, AdBlue sinks to the base of the tank, just where fuel is drawn from. At a forecourt — Shell, Kingstanding Service Station or any other — the attendants will normally help push your car away, when you ask. If you're on your own driveway around Banners Gate, leave the vehicle where it is. Stop as soon as it is safe then switch off, if the motor has already run. The next junction is where to leave if you are on the M6, under 3 miles from Banners Gate. Mileage counts — a short hop across Banners Gate is a smaller job than driving under 10 miles towards Birmingham — so tell us roughly how far it went. ## Banners Gate: what happens when our engineers turn up Our technicians come to the car wherever it has stopped, whether that's outside Sutton Park Primary, near Banners Gate United Reform Church or on your own drive. We ask what was put in, about how much, and if it has run, since those answers settle the work and our quote. That price comes over the phone, ahead of any van leaving. Next: a drain, then a full flush of the whole system. Unlike petrol, AdBlue forms crystals and attacks certain fuel-system metals, and none of it washes away by itself. Hence it matters more. Filter flushed or, where needed, replaced; clean diesel in; then a check of your car. After that our engineers start the car and check it runs properly before we leave. Most jobs are finished in roughly half an hour after we arrive, as long as your motor has not run — and the pumps our engineers use are safe on a live forecourt and quiet at night outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your policy as the van travels to you: misfuelling cover comes with many policies. ## About Banners Gate, briefly Banners Gate is a suburban area located in the West Midlands, situated approximately 5.9 miles north of Birmingham city centre.
