--- title: AdBlue in a Diesel Tank Broadgate? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/broadgate-lancashire/ location: Broadgate county: Lancashire latitude: 53.754560 longitude: -2.714640 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # Why It Happens and How to Avoid It: AdBlue in a Diesel Tank in Broadgate AdBlue already in your diesel tank? Then set this page aside for now, leave your ignition and engine off, then phone 0333 366 0103. A drain plus a thorough flush, done right where your vehicle stands around Broadgate, is usually what it needs if caught before your motor runs. Here in advance? In that case the rest explains why it comes about and what to stop it ever happening. ## Two fillers, two tanks: AdBlue in a diesel vehicle Not one liquid but two: that's how plenty of newer diesels near Broadgate and Preston carry, with diesel feeding the engine. The exhaust, not the engine, is where AdBlue goes: sprayed into the gas to fresh them, from its own tank. Different tanks, different fillers. Some vehicles keep the AdBlue filler in the boot or under the bonnet; a lot more have both together behind one flap. At the pump, your diesel side gets filled all the time. The AdBlue side is fuelled far less commonly, normally from a bottle, and normally by someone who has to stop and think where it goes. The slip lives in that gap. ## How does AdBlue in the diesel tank happen in Broadgate? It's hardly ever carelessness. Three things tend to line up. Hurry follows from the warning. The car warns you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Beech Street, or heading home in the car park outside The Station. Then the vehicle is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one. A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, once started, keeps on. Lower Penwortham or the middle of Broadgate: it takes the same few seconds either way. ## How to tell the AdBlue filler from the diesel one Whether a Broadgate forecourt or a drive over in Maudlands, spend a few seconds on these before any goes in. - Check the cap rather than going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps normally aren't. - Check the size: the smaller filler neck is, on many cars, the AdBlue one. - Open the flap and check for a label — many motors show what goes in each filler right there. - The handbook. If the filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Picking up a hire or company car, perhaps at the car park at Preston? Ask whoever drove it last before you set off, rather than when the light comes on. ## How to top up without AdBlue in the diesel tank A routine for the day the light comes on, wherever in Lancashire that is. - Stop somewhere level, engine off, with time to spare — not hurried on the side of Fishergate Hill. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, perhaps, but it does the trick. - The diesel cap stays on. Where both share a flap, confirm it's closed before the bottle comes up. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Only after that, start the car: close the cap, check again, and make sure the diesel cap was never opened. Find at step two or three that it's already gone into your diesel side? Then stop right there. Stage five is out. ## Put AdBlue in the diesel tank in Broadgate already? The short order of things, beginning with no starting your motor. The fuel pump runs on many diesels the moment your ignition is switched on — and so keep it off. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where the fuel is drawn from — so don't top up with diesel to thin it. At a forecourt — Gulf, another forecourt nearby or another — the staff will normally help roll your car clear, if you ask. Leave it where it is if you're on your own driveway in Broadgate. When your engine has been run by now, pull over somewhere safe then switch it off. Come off the Preston Bypass — under 3 miles out of Broadgate — at the first exit. Roughly how far did it go? Hopping across Broadgate is less a job than a run of under a mile to Preston, so say. ## What occurs when our engineers arrive in Broadgate Anywhere the car has stopped, whether by St Stephen's CofE School, near St Stephen's Church or on your own drive, the van travels to it. We ask what was put in, about how much, and if it's run, since the replies determine this work and the quote. No one heads out until you have heard our quote over the phone. Then that tank is drained and the fuel system purged thoroughly. More than with petrol, it counts here: the crystals form, certain metals corrode, and none of it washes away unaided, however long it is left. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before we leave, we start it and check that it's running smoothly. Unstarted vehicles usually mean a half-hour job from arrival. The kit is fine on a live forecourt, and quiet enough for a driveway after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your policy as the van travels to you: misfuelling cover comes with plenty of policies. ## About Broadgate, briefly Broadgate is a suburban area located on the riverside in Lancashire, with an elevation of around 10 metres.

Fastest of all: give a PR1 8 postcode for the van. The vehicle stays where it is. Anywhere it sits — near Gujurat Hindu Temple, on a lay-by en route to Penwortham Holme Recreation Ground, on a drive — that's where it is drained. Ring and ask rather than assuming if you're close to a border, or somewhere hard to describe, like the back of County Hall. ## Broadgate people: the short version First, the cap; then, the pour.
