In that case put this page aside for now, leave the ignition and engine off, and ring 0333 366 0103. Around Toxteth, finding it before your motor runs usually leaves a drain and a full flush where it stands. Nothing happened yet? Below, the rest of the page explains the why it occurs and the how to avoid it for good. ## Why does AdBlue in a diesel motor need its own filler? Not one fluid but two: that is how plenty of modern diesels near Toxteth and Sefton Park carry, with diesel for your motor. Its own tank holds it, and from there it goes to your exhaust, where a spray treats the gas. Each tank has its own filler. Other vehicles put the AdBlue filler in the boot or under the bonnet; a lot of others place the two side by side behind one flap. Topping up the diesel side at the pump goes on constantly. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less frequently. It's in that gap that the mistake lives. ## How does AdBlue in your diesel tank happen around Toxteth? Carelessness seldom causes it. Instead is three things coming up together. First, the warning. Low AdBlue triggers a message from the car, and letting it run dry means limp mode — so a rushed top-up, maybe before work off Park Street, or at Mosley Arms on the way home after work. Then your car is strange. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have used on the old one. 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 after it has started. Dingle or the heart of Toxteth: it is the same few seconds in both. ## Telling the AdBlue filler from your diesel filler Check these before pouring, at a forecourt around Toxteth or a driveway over in Edge Hill. A few seconds, no more. - Position can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel ones usually don't. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - Open the flap and check for a label — plenty of motors show what belongs in which inlet right there. - In your boot or under the bonnet: that is where the filler sits if it is not by your diesel cap, and the handbook says which. - Whoever had it before will know. Check when you collect a rental or fleet car — at Brunswick's car park, perhaps — not once the light appears. ## Topping up AdBlue without it reaching the diesel tank Wherever around Merseyside the light comes on, this is a routine for that day. - Stop somewhere level, engine off, with time to spare — never rushing on the side of Hughson Street. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, yes, but it does the trick. - The two under one flap? Then make sure the lid on the diesel side stays shut ahead of raising the bottle. - Finish when your tank fills or the bottle runs dry; before that, pour slowly using its own spout. - Close the cap, then check again — making sure the diesel cap remained shut the whole time. Only then, start your car. Find at the second or third step that AdBlue went in the diesel filler? That's where you stop. Don't go on to stage five. ## AdBlue in your diesel tank already, around Toxteth? What follows is a short order of things, beginning with not starting the engine. The fuel pump runs on plenty of diesels as soon as the ignition is switched on — and so leave it off. Topping up with diesel will not dilute it: rather than mixing, AdBlue drops to the bottom of the tank, right where the fuel is taken from. The staff at Esso, Shell or another forecourt will normally help to push your car clear if asked. At home around Toxteth? So the vehicle remains put. Stop as soon as it is safe then switch off, if your motor has already run. Toxteth lies under 5 miles from the M62; on it, use the next junction. Tell us about how far it went: a run towards Liverpool, under 3 miles away, is a bigger job than a short hop across Toxteth. ## Toxteth: what occurs when our technicians turn up The van comes to the car wherever it stopped — your own driveway, near Saint Gabriel's Parish Church, or outside Holy Family Catholic Primary School. The answers decide this work and the quote, so our engineers ask what went in, roughly how much, and whether it's run. That quote is given on the call, before any van leaves. Then that tank is cleared and your system purged thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Once your filter has been cleaned — or renewed, where needed — clean diesel is added, and then the vehicle gets tested. We don't leave until it has been fired up and is running properly. If your engine hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. Paying is on the day, not upfront, and you are given the paperwork an insurer wants: an engineer report and a VAT invoice. It is worth looking at your insurance while we travel to you: misfuelling cover comes with plenty of policies. ## About Toxteth Toxteth is a suburban area in Merseyside, situated on the coast near Liverpool, with Toxteth being close to several nearby places including Dingle, Princes Park, and St Michaels Hamlet.
