Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Common Side
If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off and phone 0333 366 0103. In Common Side, finding it before the engine turns normally means draining and a full flush on the spot. Not happened yet? Below, the rest of the page covers the reasons it happens and the how to prevent it for good.
Two fillers, two tanks: AdBlue in a diesel motor
Plenty of modern diesels in Marlpool, like those in Common Side, carry on two liquids; the engine takes only your diesel. Stored in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.
Each tank has its own filler. Under one flap, side by side: that's the layout on many vehicles. On others, AdBlue's filler is beneath the bonnet or in the boot instead. Diesel goes in on each filling station visit, week in, week out. Much less regularly, the AdBlue side is topped up — mostly from a bottle, by someone thinking about where it goes. It is in that gap that the mistake happens.
How AdBlue in your diesel tank happens in Common Side
It's seldom carelessness. Three things tend to line up.
The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Burnthouse Road before work, or in the car park outside New Inn on the way home.
Unfamiliar motors come second, as well. Hire cars, new motors and company vehicles put their fillers differently, and the hand reaches for the cap it used on the old one.
Third, the spout goes in: a diesel filler or AdBlue one, it goes in as readily, and once the tip begins, no part halts it. Heanor Gate or the middle of Common Side: it takes the same few seconds in both.
How to tell the AdBlue filler from the diesel one
Check these first, on a forecourt in Common Side or a driveway out in Langley. A few seconds, no more.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it rather than going by position.
- Plenty of cars fit AdBlue the smaller neck of the two.
- A label inside your fuel flap frequently says which fuel goes where, on many cars. Check for it.
- In your boot or under the bonnet: that is where your filler is if it's not by your diesel cap, and the handbook tells you which.
- Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Langley Mill.
Topping up AdBlue without it reaching your diesel tank
A routine for the day the light comes on, wherever across Derbyshire that is.
- Switch off once parked — flat ground, motor stopped, and never in a rush beside Mayfield Avenue on the verge.
- Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap works — once you've located your filler and read it.
- The diesel cap stays on. Where both sit under a flap, make sure it's closed before lifting the bottle.
- Gently is best, through the bottle's own spout, till it's full or the bottle runs out.
- Only after that, start the vehicle: close the cap, check again, and make sure your diesel cap was never opened.
Find at the second or third step that AdBlue went in the wrong tank? That is where you stop. Don't go on to step five.
AdBlue in the diesel tank already, in Common Side?
Do not start the engine: that's where the short order of things starts. The fuel pump runs on many diesels the moment your ignition is switched on — and so keep it off. Diluting it with more diesel fails, since AdBlue sinks to the base instead of blending — and that is where the fuel is sucked from.
Ask the attendants to help push the car clear of the petrol pump if you are at a forecourt — the the nearest petrol station, the Texaco or somewhere else. Your own driveway in Common Side is the place it should stay.
When your motor has run by now, stop safely then turn it off. Come off the M1 — under 5 miles out of Common Side — at the first exit. Roughly how far did it go? Crossing Common Side is smaller a job than a run of under 10 miles towards Derby, so tell us.
When our engineers arrive in Common Side, what occurs?
Our technicians come to your car wherever it has stopped, whether that's outside Corfield CofE Infant School, near The Town Ground or on your own drive. Our engineers ask what was put in, about how much, and if it's run, since the answers settle this work and our price. The quote comes on the call, ahead of any van leaving.
Draining that tank comes next, then a full flush of the system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush matters more with AdBlue than with petrol. A test is at the end: before that, fresh diesel is added, and your filter is cleaned or replaced as needed. We do not leave until it has been fired up and is running correctly.
Most jobs are done in roughly half an hour after our engineers arrive, provided the motor hasn't run — and the pumps our technicians use are fine on a busy forecourt yet quiet at night beside a house. Your insurer will ask for the engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. While we travel, take a look at your insurance documents; many carry cover for misfuelling.

Common Side and Derbyshire: AdBlue drains across the area
As a residential suburb, Common Side shares its vans surrounding areas — Heanor, Newlands — right across DE postcodes and the wider area beyond. A postcode starting DE75 7 gets the van to you fastest.
The car remains put. A drive, a lay-by on the way to Lockton Avenue Playing Fields, a side street near Heanor Baptist Church: our engineers drain the vehicle where it sits. Ring and ask rather than assuming if you're near a border, or somewhere hard to describe, like the back of Wilmot Street Centre.
For Common Side people, the short version
Read the cap before you tip. Petrol in Diesel empties it where it stands, anywhere around Derbyshire, if AdBlue has gone in your diesel tank regardless — and so leave the car off then call 0333 366 0103.
