AdBlue in the Diesel Tank in Fiddlers Green? Keep It Switched Off
Engine off, ignition off: that is where you begin if AdBlue has got into your diesel tank. Urea mixed in water is all AdBlue is. Not like fuel, it neither ignites nor mixes, and no harm starts until the motor sucks it round. Caught before the engine has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is in Fiddlers Green. No step comes before ringing 0333 366 0103.
Fiddlers Green, AdBlue in your diesel tank: what to do at once
Things to do:
- So nobody can switch the ignition on, take the keys out.
- Hazards on, if moving traffic is at all close.
- Which product, and roughly how much quantity? Hang on to the bottle or the till receipt, and our engineers will see.
- Call just where you are. Say a GL51 0 postcode or the nearest street name, and no one has to search for you.
Do not:
- Not even briefly, and not to roll the car: the engine stays off.
- Switching your key to ignition alone sets your pump going on many diesels. Avoid it.
- AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel won't weaken it.
- Even a short stretch up Beverley Croft is too far to drive it.
- Emptying that tank yourself by the road is not worth trying.
Moving the vehicle off the island is a job for attendants to help with, whichever Fiddlers Green forecourt you're on, the Asda included. Parked on your own drive? Then it remains exactly as it is.
What does AdBlue do in a diesel tank?
Meant for your exhaust, AdBlue has no business in your motor. Its own tank keeps it, and from there it's fed into the exhaust, and there it treats the gas. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.
It doesn't combine. Once it's poured into the tank, AdBlue acts nothing like diesel. Denser than diesel, it drops and pools underneath it — the very place the pickup sucks from. Simplest of all: one that had AdBlue in Hayden last night and has not been started since. The AdBlue waits at the foot of your tank, undrawn — though it will be the first thing through once your motor runs, ahead of any diesel at all.
Once it's pulled in, the harm comes in two forms. Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filter elements and tiny channels; and, since it attacks some metals, every part it reaches keeps suffering for as long as it stays inside. Lines holding AdBlue mean harm by morning for a vehicle sitting in Fiddlers Green. Only inside that tank, it stays the same. The water in it does damage of its own: your high-pressure pump and your injectors depend on diesel to lubricate them, and water offers them nothing.
AdBlue in a diesel: why it is regularly worse than petrol
An issue of thinned fuel is what you end up with from fuelling a diesel with petrol at the Esso. It mixes with the diesel, and while it's in the tank it causes no damage; the harm comes from running the engine on it.
AdBlue in a diesel is a fault of the wrong substance altogether. Not burning, it cannot simply be run through. Deposits and corrosion stay after the next tankful, and AdBlue splits back out of your diesel, and so thinning it won't help. That is why the flush counts more, and turning the key "to see" does more harm here than nearly any other slip — in Golden Valley or the centre of Fiddlers Green equally.
With AdBlue, the good news is no distinct from petrol. Anywhere around Gloucestershire the car has stopped, an unrun motor leaves the AdBlue yet in the reservoir: the simplest part of any fuel system to empty.
How AdBlue ends up in a diesel tank in Fiddlers Green
In dim light, two caps side by side — the AdBlue one and the diesel cap, occasionally under a single flap — can look the same. Nobody means it; plenty of designs allow it. Mostly it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.
The ways it takes place are few and familiar. A warning light comes on during the school run, and the top-up happens in a hurry outside St Thomas More Catholic Primary School. A bottle is poured in at the end of the day on a drive just off Alder Court. One more version: darkness, the car park by The National Hunt, and a driver using that flap for the first time.
It comes up most in a rental, a brand-new vehicle, a fleet car, or the spare vehicle in a family with one of each fuel types — the vehicles drivers know the least. Wherever you're around Fiddlers Green or the rest of Gloucestershire, it is the same slip and the same first answer: leave it off.
Started the motor with AdBlue in the diesel tank in Fiddlers Green?
If so, the AdBlue is no longer in that tank. The filter and lines have had it pulled along, and some running time takes it on to the high-pressure pump and every injector.
Lumpy running, smoke, lost power, dashboard warnings or cutting out: each may appear, perhaps midway across Fiddlers Green or returning from Elm Farm Open Space. Stop as soon as it is safe, switch off, and do not restart it to check. With each start, more of that is pulled through.
On the M5, under 3 miles from Fiddlers Green, the next junction is where to exit, and anywhere safe is where to stop — not driving on.
How far it went matters. A few hundred yards across Fiddlers Green to the car park by Ice House (earthwork) is a very different job from a run towards Gloucester, under 10 miles away, with the AdBlue reaching further into your system with each mile. Roughly how far had it come? Tell us.
There is more to flush once your engine has been run, and we do all of it where the vehicle has ended up. Very rarely does it leave lasting damage when it's spotted early.
Fiddlers Green: how AdBlue is drained from a diesel
Anywhere it has come to rest around Fiddlers Green — a filling station, a layby, a drive, a road beside YMCA — the van travels to your car. The work rests on three answers, which we get first — which fluid went in, the quantity, and if the engine has turned over.
The contaminated diesel and the urea come out together when your tank is emptied, right there. Residue from AdBlue will not wash out unaided, so the fuel system gets a careful flush, which counts far more here than for petrol. Testing the vehicle follows at the end, once fresh diesel is added and the fuel filter is cleaned or, where necessary, swapped. Not run? In that case count on about half an hour on site for most jobs. Our pumping gear is explosion-proof, so a live filling station is no issue, and it is quiet enough for a residential street late at night.
Clean diesel goes in to prime the fuel system, and that is the final step. Starting it comes next, and then you head off from where the vehicle is parked, by Cheltenham Spa or on a driveway around Fiddlers Green. Our technicians make sure it runs correctly on fresh diesel before we leave. The entire job is done where the vehicle is, so it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come afterwards.

Fiddlers Green: what AdBlue in a diesel tank costs to fix
Not one flat price could be honest, since each job is different. Three things shift the price: whether your engine has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one rests on whether our van can get to it safely, and an open driveway is simpler than a tight gap behind Hesters Way Community Resource Centre.
That is why each call from Fiddlers Green starts with the same three questions, asked before giving a figure, not after: what got in, how much, and if it has run. The replies turn a range into a straight quote.
Before a van heads out, you are told our quote by phone. And payment is on the day, by card or by phone, with nothing in advance. As the van is travelling, check your insurance: plenty cover misfuelling.
