Usually, when your engine has not turned, it's emptied and fully rinsed where your car sits in Higher Penwortham. Nothing happened yet? Below, the page covers the reasons it takes place and the ways to avoid it altogether. ## Why does AdBlue in a diesel vehicle need its own filler? Plenty of modern diesels in Riverside Docklands, like those in Higher Penwortham, run on two liquids; the motor takes just your diesel. AdBlue's own tank keeps it, and from there it is sent to the exhaust, where spraying treats the fumes. There's a filler for each tank. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in at every filling station call-out, week in, week out. Much less often, the AdBlue side is filled — normally from a bottle, by a person thinking about where it goes. It is in the gap that the error happens. ## How does AdBlue in your diesel tank occur in Higher Penwortham? It's hardly ever carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a driveway off Cop Lane before work, or in the car park at Fleece Inn on the way home. The old car's cap is where your hand goes — yet a rental car, a new motor or a company car puts the fillers somewhere else. That's the second thing: an unfamiliar car. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour once it has started. It's a few seconds, whether out in Penwortham or bang in the centre of Higher Penwortham. ## Which filler is for AdBlue, and which for diesel? A couple of seconds is all the checks take — so check them before you pour anything, on a drive in Middleforth Green or a forecourt around Higher Penwortham. - Where it sits can mislead; the cap doesn't. AdBlue caps are often blue or bear the word "AdBlue" — diesel ones normally don't. - Plenty of vehicles give AdBlue the smaller filler of the two. - Check inside your fuel flap: plenty of vehicles carry a label there showing which fuel goes where. - The handbook shows where it is if the filler is not next to the diesel cap: your boot, or under the bonnet. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Preston, ask before you leave, not when the light comes on. ## How to top up without AdBlue in your diesel tank On the day the light appears — wherever you are across Lancashire — a routine to use. - Not in a rush on the side of Liverpool Road, not on a slope, not with your motor running: park and switch off properly. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Silly, yes, yet it does the trick. - The diesel cap remains on. Where both sit under a flap, confirm it's shut before lifting the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Close the cap, then check once more — confirm the diesel filler stayed closed throughout. After that, start the vehicle. If at step two or three you find you have already poured into the diesel side, stop there. Do not go on to step five. ## Already put AdBlue in the diesel tank in Higher Penwortham? What follows is a short order of things, starting with not starting the engine. Keep the ignition off as well, since on many diesels it by itself starts the fuel pump. Thinning it with extra diesel fails, because AdBlue settles to the bottom rather than mixing — and that is where the fuel is sucked from. Ask the staff to help push the vehicle clear of the pump if you're on a forecourt — the the nearest petrol station, the Esso or anywhere else. Leave it where it is if you're on your own driveway in Higher Penwortham. If the engine has already run, stop as soon as it is safe and switch off. On the M65, under 5 miles from Higher Penwortham, that means the next junction. Tell us roughly how far it went: a run towards Preston, under 3 miles away, is a bigger job than a short hop across Higher Penwortham. ## Our arrival in Higher Penwortham, and what occurs next By Penwortham Primary School, near Priory Lane Community Centre or on your own driveway: wherever the vehicle has stopped, our technicians come to it. The answers settle this work and the quote, and so we ask what was put in, about how much, and whether it's run. That price is given on the call, before any van leaves. Emptying that tank comes next, then a full flush of the system. Much more than with petrol, it matters with AdBlue: crystals form, certain metals corrode, and none of it clears away unaided, however long it is left. Once the filter is cleaned — or replaced, if required — clean diesel is added, and finally your car gets tested. Then our technicians fire it up and check it runs properly before we leave. If your motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. Your insurer will ask for the engineer's report and your VAT invoice, and you get both once the job is done. Payment is on the day, with no deposit. Misfuelling cover is included in many insurance policies — and so make use of the wait to check yours. ## About Higher Penwortham, for a moment Higher Penwortham is a suburban area located near Preston in Lancashire, sitting at an elevation of 29 metres above sea level.
