AdBlue in a Diesel Tank in Soham? Don't Start It
Motor off, ignition off: that's where you begin if AdBlue has got into your diesel tank. AdBlue is urea dissolved in water. It doesn't burn, it doesn't mix with diesel, and the harm it does begins when the fuel system draws it in. Caught before the engine has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is in Soham. Phone 0333 366 0103 before you do anything else.
Your next steps right now, Soham: AdBlue in the diesel tank
Do these:
- So no one can turn the ignition on, take your keys out.
- Hazards on, if moving traffic is at all near.
- Which product, and about how much volume? Hang on to the bottle or the till receipt, and we will see.
- Call right where you are. Say a CB7 5 postcode or the closest street sign, and no one has to search for you.
Don't do these:
- No starting the motor — not briefly, not to shift your car.
- Many diesels power their pump the instant the ignition goes on, so keep it off.
- Don't top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
- Even a short stretch along High Street is too far to drive the vehicle.
- Don't try to drain the car yourself by the kerbside.
Rolling the car away from the pumps is a job for staff to help with, whichever Soham forecourt you are on, the Esso or any other. At your own driveway, do not move it at all.
AdBlue in a diesel tank, and what it does there
Not your engine but the exhaust is where AdBlue is meant to go. From a separate tank it is fed directly to your exhaust, treating what the engine lets out. A fuel pump is not designed to take it, and AdBlue was never supposed to travel through one.
Fuel blends; AdBlue, after poured in, will not. The behaviour is nothing like fuel's. The intake takes fuel from the deepest part of that tank, and that's just where AdBlue settles: as it is denser than diesel, it sinks. Easiest of all: one that had AdBlue in Soham Cotes overnight and hasn't been started since. The AdBlue sits at the base of that tank, undrawn — though it will be first through once your engine runs, before any diesel at all.
Two kinds of harm come from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filters and narrow channels; and, since it eats at some metals, each part it reaches keeps suffering for as long as it stays inside. If the AdBlue is in the pipework, waiting overnight around Soham makes things worse. In that tank alone, waiting costs nothing. And there is the water: it offers no lubrication to the parts that need it most — the high-pressure pump and each injector.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Top up a diesel with petrol in error over at the BP, and this issue is diluted fuel. It mixes with the diesel, and whilst it's inside your tank it does no harm; the harm comes from running the engine on it.
AdBlue in a diesel is an issue of the wrong substance altogether. It can't simply be run through, because it does not burn. It does not stay mixed, so it cannot be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than nearly anywhere else, whether the car is in Barcham Corner or the middle of Soham.
The good news is the same as with petrol. Not started? Then the AdBlue waits only inside your tank, the simplest bit of the entire system to empty, anywhere your vehicle has come to rest around Cambridgeshire.
How does AdBlue end up in a diesel tank around Soham?
In dim light, two caps together — the AdBlue cap and the diesel one, now and then under a single flap — may appear the same. Nobody means it; plenty of layouts invite it. Most of the time it occurs with a bottle bought on the way home and poured in on the drive, not at the pump.
Usually, it occurs in one of a few familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside St Andrew's CofE Primary School the top-up is hurried. A driver pours the bottle in outside their house, just off Clay Street, as the day ends. Otherwise, in dim light by Red Lion, the car is topped up by a driver opening that flap the first time.
It happens most in the cars motorists know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. Wherever around Cambridgeshire, Soham as well, the slip does not change, and neither does the first step: leave it switched off.
Already started the engine with AdBlue in your diesel tank in Soham?
Then that tank is no longer where the AdBlue is. Given any running time, it goes on to the injection pump and every injector, after passing through the fuel filter and lines.
Expect lumpy running, smoke, lost power, warnings on your dash, or a cut-out — coming back from Soham United Football Club, say, or midway across Soham. Stop when it is safe. Switch off. Keep it off instead of testing it again. More of that is pulled through with each start.
Soham sits under 15 miles from the M11; if you were on it, leave by the next junction and pull up safely rather than driving on.
Hopping across Soham to the car park by War Memorial is one matter; driving towards Ely, under 10 miles away, is another, because each mile carries the AdBlue further in. So distance matters. Let us know about how far it had come.
Wherever the car came to a stop is where all of it gets done, even with more to clean out after your engine has been started. Very seldom does it leave permanent damage if it's noticed soon.
What clearing AdBlue from a diesel involves in Soham
A street by Soham Rail Disaster memorial, a drive, a layby or a filling station: wherever your car has stopped in Soham, we come to it. Three replies shape the job, so first our technicians ask which fluid got in, about the amount, and if your motor has turned over.
The contaminated diesel and the urea leave together after your tank is drained, on the spot. With AdBlue, more so than with petrol, flushing counts: the whole system is cleaned all the way through since what remains won't flush away by itself. Next, your filter: cleaned, or changed when it has to be. Then fresh diesel, and then a check of your car. The majority of these jobs are a half-hour job once we get there, if the engine hasn't run. Explosion-proof pumps mean a busy forecourt sensible to work on, and they're quiet enough to spare the street at night.
Clean diesel goes in to prime your system, and that's the final step. Starting the car comes next, and then you set off from where the vehicle is parked, outside the nearest station or on a driveway in Soham. The test before our engineers leave is that it runs properly on fresh diesel. Our technicians do it all wherever your car has stopped, and it never needs to go to a workshop. At the end, there is paperwork for the insurer: a VAT invoice plus a written report from the engineer.

What does AdBlue in a diesel tank cost to sort out around Soham?
No single figure would be honest, since each job is different. The cost shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that went in. After that it depends on where the vehicle is and whether a technician can reach it safely, which is easier on an open driveway than in a tight spot behind Soham Baptist Church.
With that reason, every enquiry from Soham opens by asking the same trio — what got in, how much, if the engine ran — ahead of any figure. When they are answered, a range turns into one firm number.
Priced by phone before the van sets out, it is paid for on the day — card or phone, nothing in advance. Look at your policy whilst we're on the way: plenty include misfuelling cover.
