AdBlue in a Diesel Tank in Wymans Brook: Why It Happens and How to Prevent It
Keep the engine and ignition off and phone 0333 366 0103 first — the rest can wait when AdBlue is already in your diesel tank. In Wymans Brook, finding it before the engine runs normally leaves draining and a full flush on the spot. Nothing happened yet? Below, the rest of the page explains the reasons it occurs and the ways to prevent it altogether.
Why does AdBlue in a diesel vehicle need its own filler?
Diesel feeds your motor — but plenty of current diesels driven about Wymans Brook and Swindon hold another fluid too. Stored in a tank of its own, AdBlue is fed into your exhaust gas and cleans it.
Each tank has its own filler. Some vehicles keep the AdBlue filler in the boot or under the bonnet; plenty of others have both side by side under one flap. Topping up the diesel side at the petrol pump happens 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 frequently. Mistakes happen in the gap between them.
Wymans Brook: how AdBlue in the diesel tank occurs
Rarely is it carelessness: usually three things coincide.
On a driveway off Roman Hackle Avenue before work, or in the car park at The Ridge on the way home: that is where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low your car tells you, and once it is empty, limp mode kicks in.
Unfamiliar cars are second, as well. Rentals, new cars and company vehicles place their fillers in new places, and the hand reaches for the cap it used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. Whether it occurs in Marle Hill or the middle of Wymans Brook, it's the same few seconds.
How to tell the AdBlue filler from the diesel one
A few seconds is all these take — so check them before you tip anything, on a drive in St Pauls or a forecourt in Wymans Brook.
- Where it sits can mislead; the cap does not. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel caps normally don't.
- The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
- The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
- In your boot or under the bonnet: that is where your filler sits if it's not by the diesel cap, and the handbook tells you which.
- Whoever had it before will know. Ask when you collect a rental or fleet car — from Cheltenham Spa's car park, say — not once the warning comes on.
AdBlue top-ups that never reach your diesel tank
Wherever in Gloucestershire the light comes on, here is a routine for the day.
- Not in a rush on the side of Mandarin Way, not on a slope, not with the engine running: park then switch off properly.
- Find the AdBlue filler, read the cap, and say the word "AdBlue" aloud as you unscrew it. It sounds silly. It works.
- Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Gently is best, through the bottle's own spout, until it's full or the bottle runs out.
- Only then, start the car: close the cap, check once more, and make sure the diesel cap was never opened.
Stop there if you find, at step two or three, that you've already poured into your diesel side. Skip step five altogether.
Already put AdBlue in the diesel tank in Wymans Brook?
Do not start the motor: that's how the short order of things starts. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is sucked from — so do not top up with diesel to thin it.
Ask the staff to help push the vehicle away from the pump if you're at a forecourt — the Tesco, the Shell or somewhere else. Your own drive in Wymans Brook is the place it should stay.
Already run? Pull over when it is sensible, then switch off. On the M5, under 3 miles from Wymans Brook, that means the next junction. Tell us about how far it went: a run towards Gloucester, under 10 miles away, is a bigger job than a short hop across Wymans Brook.
What occurs when our technicians arrive in Wymans Brook
By Gardners Lane Primary School, close to St Nicholas' Church or on your own driveway: wherever the car has stopped, our technicians come to it. What fluid went in, the quantity, and whether it ran: our technicians ask because the answers decide both work and price. On the call itself, you are told the price — ahead of anything else.
Then that tank is drained and the fuel system flushed thoroughly. Much more than with petrol, it counts here: the crystals form, certain metals corrode, and none of that washes out unaided, no matter how long it sits. Once your filter has been cleaned — or replaced, where needed — fresh diesel is added, and then your vehicle gets tested. Your engine is started next and tested to be sure it runs smoothly, all before we go.
Most jobs are finished in about half an hour after our engineers get there, as long as your motor hasn't run — and the pumps we use are fine on a busy forecourt yet quiet at night beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is included in plenty of insurance policies — so make use of the wait to look at yours.
