Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Daisyfield
Leave the engine and ignition off and ring 0333 366 0103 now — the rest can wait if AdBlue is already in your diesel tank. Caught before the motor runs, it is normally a drain and a thorough flush, done where the car is around Daisyfield. Nothing happened yet? Below, the page covers the why it occurs and the ways to avoid it altogether.
Why does AdBlue in a diesel vehicle need its own filler?
Plenty of current diesels on the roads round Daisyfield and Little Harwood carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the pump, the diesel side is topped up all the time. Far less often, the AdBlue side is filled — normally from a bottle, by a person working out where it goes. It is in that gap that the slip lives.
Daisyfield: how AdBlue in the diesel tank occurs
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 completely, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Moss Street before work, or in the car park outside Red Lion on the way home.
Then the vehicle is new. A hire car, a new car or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one.
Nothing halts the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Daisyfield or out in Cob Wall.
Which filler is for AdBlue, and which for diesel?
Whether a Daisyfield forecourt or a drive over in Hole House, spend a few seconds on these before any goes in.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally is not. Read it instead of going by position.
- On many cars, the size tells: AdBlue has the smaller filler neck.
- Check inside your fuel flap: many vehicles carry a label there saying which fuel goes where.
- The handbook. If your filler isn't by the diesel cap, it's in the boot or under the bonnet, and the handbook says which.
- Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Blackburn.
How to top up without AdBlue in the diesel tank
When the light goes on, wherever across Lancashire, follow this routine.
- Stop somewhere level, engine off, with time to spare — not hurried on the side of Clinton Street.
- Locate the AdBlue filler, check the cap, and speak the name "AdBlue" aloud as unscrewing it. It sounds silly. It does the trick.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Shut the cap, then look once more — confirm the diesel cap remained closed the whole time. Only then, start the car.
Spot at stage two or three that it's already gone into the diesel side? So stop just there. Never go on to step five.
Daisyfield: already put AdBlue in the diesel tank?
Then the order of things is short. Don't start the engine. Keep your ignition off too, since on plenty of diesels switching it on alone starts your fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is pulled from.
If you are at a forecourt, whether it is the Shell or the Tesco, ask the attendants to help push the car away from the petrol pump. On your own drive in Daisyfield? Then your car remains put.
If the motor has already run, stop as soon as it is safe then switch off. Leave the M65 — under a mile out of Daisyfield — at the next junction. Mileage counts — a quick hop across Daisyfield is a smaller job than driving under 10 miles to Preston — so tell us about how far it went.
What happens when our technicians get there around Daisyfield
Our engineers come to your car wherever it has stopped, whether that's outside Daisyfield Primary School, close to St Stephen or on your own drive. Both the work and the quote depend on three replies — what fluid, which amount, and if it has run — so our technicians ask. On the phone call itself, you are told the quote — before anything else.
Then the tank is emptied and your system purged thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush matters more here than with petrol. Testing is last: before that, fresh diesel is added, and the fuel filter is flushed or replaced as needed. Next we start the engine and check it runs smoothly before we go.
With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which the engine hasn't run take roughly half an hour once our engineers arrive. Your insurer usually wants an engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. It is worth checking your insurance while we travel to you: misfuelling cover is included with many policies.
