Don't Start It: AdBlue in a Diesel Tank in Roffey
If AdBlue has gone into your diesel tank, keep the motor off then leave the ignition off. AdBlue is urea mixed in water. Not like fuel, it neither burns nor mixes, and nothing starts until the motor pulls it through. If the engine hasn't run yet, AdBlue in a diesel tank is normally drained and thoroughly flushed where the vehicle sits in Roffey. Before anything, call us on 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around Roffey
Things to do:
- Pocket the keys, and that stops someone turning the electrics on.
- Near moving traffic? Then put your hazards on.
- Hold on to the receipt or the empty bottle, so you can tell us what was put in and about how much.
- Ring right where you are. Quote a RH12 4 postcode or the closest street sign, and no one has to hunt for you.
Not to do:
- Not even for a second, and not to roll your vehicle: your engine remains off.
- Do not switch your ignition on. On many diesels that alone runs the fuel pump.
- Do not top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.
- Never drive the vehicle anywhere, not even a short way down Crawley Road.
- No emptying it yourself, either, on the verge.
On a forecourt around Roffey, whether it is the Esso or another one, ask the staff to help you push the vehicle away from the petrol pump. Stopped on your own driveway? Then it stays exactly as it is.
What does AdBlue do in a diesel tank?
AdBlue is made for the exhaust, not the motor. Kept in a dedicated tank, it is injected into the exhaust to clean the gases. A fuel pump is not made to cope with it, and AdBlue was never supposed to go through one.
Tipped in with the diesel, it stays separate instead of blending — quite different from fuel. It's heavier than diesel, and so it sinks and gathers at the bottom of your tank, which is where the pickup draws fuel from. Once your system runs, the AdBlue is first to be pulled through. Before then it waits beneath your diesel, and that is why a car topped up in The Common last night and never started stays the straightforward case, provided nobody touches the key.
From there it does two kinds of damage. It eats at certain metals found in fuel components, working on whatever it touches till it is cleared completely. And when the water evaporates, the urea forms crystals that block filters and lodge in tiny channels. Overnight, a vehicle parked around Roffey with AdBlue through its pipework gets worse; where it is only in that tank, nothing changes. Then there is the water: it offers no protection to the parts that rely on it most — the injection pump and each injector.
Why is AdBlue in a diesel regularly the bigger fault?
A fault of thin fuel is what you end up with after filling a diesel with petrol from the BP. Damage just comes from running on it. Mixed into the diesel and sitting in the tank, it does nothing.
With AdBlue in a diesel, the liquid as such is simply the wrong one. It does not burn, and so it cannot just be run through. Nor can it be thinned, because it separates again — and the next tankful won't clear away crystals or corrosion. So the flush counts more with AdBlue, and trying the engine "to see", in the heart of Roffey or out in Doomsday Green, does more harm than nearly any other slip.
With AdBlue, the good news is no distinct from petrol. Wherever in West Sussex your car has stopped, an unrun motor leaves the AdBlue still inside the tank: the simplest bit of any fuel system to empty.
How does AdBlue end up in a diesel tank around Roffey?
After dark, two caps side by side — the AdBlue one and the diesel one, occasionally under a single flap — can look the same. Nobody means it; plenty of designs allow it. A container picked up when driving home and tipped in at home, instead of at the filling station, is the usual route.
A few familiar ways account for the majority of them. A warning light comes on during the school run, and the top-up occurs in a hurry outside St Robert Southwell Catholic Primary School, Horsham. In the evening, a container is tipped in on a drive close to Jubilee Close. Or a driver new to that flap refills your vehicle in dim light, stopped in the car park by The Norfolk Arms.
It crops up the most in a rental, a new vehicle, a company car, or the other motor of a family with both fuels — the cars people know the least. An identical mistake, same first response — leave it off — wherever you happen to be in Roffey or the remainder of West Sussex.
Started the motor with AdBlue in your diesel tank in Roffey?
Then the AdBlue has left your tank. It's been drawn through the filter and your lines, and if the engine ran for any time, it has got to the high-pressure pump and the injectors.
Watch for rough running, smoke, lost power, lights on your dash, or a stall — coming back from Innes Memorial Cricket Ground, perhaps, or midway across Roffey. Stop as soon as it is safe, switch off, and do not restart the vehicle to check. With each start, more of that is pulled through.
Leave the M23, under 5 miles from Roffey, at the next junction and park somewhere safe, not carrying on.
Hopping across Roffey to the car park by All Saints' Church is one thing; heading for Brighton and Hove, under 25 miles away, is another, since every mile carries the AdBlue further in. So distance matters. Let us know roughly how far it had come.
We do all of the rinsing where your car has come to a stop, and once the engine has been run there is more of it. Spotted soon, it very seldom leaves long-term damage.
What clearing AdBlue from a diesel involves in Roffey
The car remains where it is, whether that is a road near Roffey Club, a driveway, a lay-by or a forecourt around Roffey, and our van comes to it. Which fluid got in, about the quantity, and if the motor has been run: we ask first, since those shape the job.
Then that tank is emptied where your car stands, and so the polluted fuel and the AdBlue come out together. A full flush matters much more after AdBlue than after petrol, since residue won't wash away on its own. After that, the filter: flushed, or changed if it has to be. After that clean diesel, and then a test of your vehicle. The majority of these jobs are a half-hour job once our technicians arrive, provided your engine hasn't run. Our equipment is explosion-proof, and so a busy filling station is no fault, and it is hushed enough for a residential street after dark.
The final step is to bleed your system on fresh diesel. Starting the car comes next, and then you set off from where the car is parked, by Littlehaven or on a driveway in Roffey. We make sure it runs correctly on new diesel before we go. No garage is required at any stage, with the entire job done on the spot. Insurers ask for a VAT invoice and an engineer report, and both come at the end.

Roffey: what AdBlue in a diesel tank costs to fix
Because each jobs differ, a single figure wouldn't be honest. The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where the car is and whether a van can reach it safely, which is simpler on an open drive than in a tight gap behind St. Andrew's Methodist Church.
Before a figure, not after, each call from Roffey begins with three questions: the fuel, the quantity, plus whether it ran. Those answers narrow a range down to one figure.
Priced by phone before the engineer heads out, the job is settled that day — card or phone, nothing in advance. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.
