Avoiding AdBlue in a Diesel Tank in Biscot: Why It Occurs
If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and your ignition off then phone 0333 366 0103. Around Biscot, catching it before your motor turns normally means draining and a thorough flush where it stands. Reading before the event? Then what follows explains how it comes about and how to prevent it ever happening.
Why does AdBlue in a diesel motor need its own filler?
Plenty of modern diesels around Luton, as well as Biscot, run on two liquids; your engine takes just your diesel. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.
Every tank has one filler of its own. Plenty of cars share a single flap for both, whereas others move the AdBlue filler to the boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less often. It's in the gap that the error happens.
How does AdBlue in your diesel tank happen around Biscot?
It's rarely carelessness. Three things tend to line up.
Hurry comes from the warning. The car tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done quickly, before work on a driveway off Norman Road, or on the way home in the car park at The BIscot Mill.
The old car's filler is where the hand goes — yet a hire car, a new motor or a company car keeps the fillers somewhere else. That's a second factor: an unfamiliar car.
Nothing halts the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Bury Park or the middle of Biscot: it is the same few seconds either way.
Telling the AdBlue filler from your diesel filler
Be it a Biscot forecourt or a drive over in Limbury, spend a couple of seconds on these before any goes in.
- The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap normally isn't. Read it instead of going by where it sits.
- The size. On many cars the AdBlue filler neck is the smaller of the two.
- Lift the flap and look for a label — many cars show what belongs in each filler right there.
- The handbook shows where it lives when 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 outside Luton, ask before you leave, not when the light comes on.
Keeping AdBlue out of the diesel tank when you top up
A routine for the day the light comes on, wherever around Bedfordshire that is.
- Turn off once parked — flat ground, engine off, and not in a rush beside Dane Road on the verge.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on.
- Finish when your tank is topped up or the bottle runs dry; before that, tip gently using the built-in spout.
- Close the cap and check again. Make sure your diesel cap was never opened. Only then start the vehicle.
Stop there if you find, at step two or three, that you've already poured into the diesel side. Stage five stays out.
Already put AdBlue in the diesel tank in Biscot?
Brief order, then. Top of it: the engine remains off. The fuel pump starts on plenty of diesels the moment your ignition is switched on — and so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so don't top up with diesel to thin it.
On a forecourt — Shell, Gulf or another — the attendants will usually help push the vehicle away, when you ask. If you are on your own drive around Biscot, leave the car where it stands.
Already started? Stop when it is sensible, then turn off. On the M1, under 3 miles from Biscot, that means the next junction. A short hop across Biscot is a smaller job than a run towards St Albans, under 15 miles away, so tell us about how far it went.
Biscot: what takes place when our engineers arrive
Outside Denbigh Primary School, close to St Andrew's Church or on your own drive: wherever your car has stopped, we come to it. What fluid was put in, the quantity, and whether it ran: we ask because the answers set both work and quote. You get that price on the phone, before anyone sets off.
Draining your tank comes next, followed by a thorough flush of the fuel system. More than with petrol, it matters with AdBlue: crystals build up, certain metals corrode, and nothing washes out unaided, however long it sits. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. After that our technicians fire it up and confirm it runs correctly before we go.
If your motor has not 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 at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.

Assuming doesn't help at the back of St Monica's Day Centre, on a border, or somewhere awkward to pin down; ring and check.
