Don't Start It: AdBlue in a Diesel Tank in Church End
Motor off, ignition off: that's where you begin if AdBlue has gone into your diesel tank. In plain terms, AdBlue is just urea in water. Unlike fuel, it neither ignites nor mixes, and no harm happens until the motor pulls it round. If the engine has not run yet, AdBlue in a diesel tank is normally drained and thoroughly purged where your car sits in Church End. Phone 0333 366 0103 before you do anything else.
What to do straight away, Church End: AdBlue in the diesel tank
Do:
- Pocket your keys, which prevents anyone turning the electrics on.
- Put the hazards on if you're anywhere near moving traffic.
- Which fluid, and roughly what quantity? Save the bottle or the receipt, and we will know.
- Tell us a postcode starting CM6 2, or whichever street is nearest, and our van finds you straight — so ring from wherever you are.
Not to do:
- No starting your motor — not briefly, not to shift your car.
- Plenty of diesels power their fuel pump the instant your ignition comes on, and so leave it off.
- Pouring in more diesel does not help: AdBlue separates out rather than thinning.
- Never drive it anywhere, not even a short distance down Bigods Lane.
- Do not try to drain the vehicle yourself by the kerbside.
The attendants working at any Church End filling station — the Tesco included — will usually help pushing it clear if you ask. Parked on your own drive? Then it stays exactly as it is.
What does AdBlue do in a diesel tank?
AdBlue is made for your exhaust, not the engine. From a separate tank it is fed directly to your exhaust, treating what your engine emits. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.
Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It's heavier than diesel, so it sinks and collects at the bottom of that tank, which is where the pickup draws fuel from. When your pump runs, the AdBlue is first to go through. Until then it sits beneath the diesel, and that is why a car filled in Little Easton last night and never started remains the straightforward case, as long as no one touches your key.
After it is sucked in, the damage takes two forms. It eats at certain metals found in fuel components, working on whatever it reaches until it is cleared completely. And when the water goes, the urea turns into crystals that block filters and lodge in tiny channels. By daybreak, a vehicle parked in Church End with AdBlue through its pipework grows worse; if it's only in your tank, it doesn't. Water lubricates nothing. The high-pressure pump and each injector depend on diesel flowing through them, and so the water part harms them in its own right.
Why is AdBlue in a diesel commonly the bigger issue?
An issue of thin fuel is what you end up with after filling a diesel with petrol from the Gulf. Damage just comes from running on it. Blended into your diesel and left in that tank, it does nothing.
The issue with AdBlue in a diesel is a totally unsuitable liquid. Not burning, it can't simply be run through. It does not stay mixed, and so it can't 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 your motor "to see" costs more here than almost anywhere else, whether the car is in Brookend or the middle of Church End.
The same good news applies as with petrol. If your motor hasn't run, the AdBlue is still inside your tank, and that tank is the easiest part of a fuel system to clear, wherever in Essex your car is standing.
How does AdBlue end up in a diesel tank around Church End?
Plenty of motors put the AdBlue cap alongside the diesel cap, now and then behind a single flap, and after dark the two may appear the same. No one intends it. Usually it's not the forecourt: a driver picks up a container driving home and pours it in outside the house.
A few familiar ways cover most cases. Rushing, outside Dunmow St Mary's Primary School, after a warning light came on during the school run, a parent refills the car. After work, a container goes in on a drive near Church End. Otherwise, in dim light outside The Angel and Harp, the vehicle is topped up by a driver using that flap for the first time.
It happens most in the motors motorists know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you are around Church End or the rest of Essex, it is the same error and the same first answer: leave the vehicle off.
Already started your engine with AdBlue in the diesel tank in Church End?
The AdBlue has left your tank, then. It has been pulled through your filter and the lines, and if your motor ran for any time, it has reached your high-pressure pump and the fuel injectors.
Maybe coming back from Merks Hill Wood, or midway across Church End, your motor may go lumpy, smoke, lose pace, flash your dash or cut out. Pull over when safe. Switch off. Keep the vehicle off instead of testing it again. Each start pulls more of it through.
If you were on the M11, under 10 miles from Church End, come off at the next exit and stop somewhere safe instead of pressing on.
How far it went counts. A few hundred yards across Church End to the car park by Saint Mary the Virgin, Great Dunmow is a very different job from a run towards Chelmsford, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile. Let us know about how far it had come.
Wherever the vehicle came to a stop is where all of it gets done, even with more to rinse out after the engine has been run. Lasting damage is very uncommon when it is noticed quickly.
Church End: how AdBlue is cleared from a diesel
The car stays put, whether that is a street beside St Mary's Room, a driveway, a layby or a forecourt around Church End, and the van comes to it. The job depends on three replies, and our engineers ask for before all else — which fluid was put in, the amount, and whether your motor has run.
Next, emptying the tank on the spot removes the polluted diesel along with the AdBlue together. What remains from AdBlue will not flush out unaided, so the whole system gets a careful flush, which counts far more here than with petrol. Next, your filter: cleaned, or changed if it has to be. Then clean diesel, then a check of the car. The majority of these jobs are a half-hour visit once we get there, if the engine hasn't run. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house after dark.
Clean diesel goes in to bleed the fuel system, and that is the last step. At that point our technicians start it and you head off, whether from a parking space at Stansted Airport or a drive in Church End. Our technicians confirm it runs properly on new diesel before we leave. We do it all wherever your car has ended up, and it never needs to go to a workshop. You receive a VAT invoice and an engineer report later on, which is what insurers ask for.

What does AdBlue in a diesel tank cost to sort out around Church End?
There is no honest single quote, because the jobs are not the same. What shifts the price is, first, whether your engine has run and for how long; then how much AdBlue was put in; and after that where the car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight spot behind Dunmow Youth Centre.
With that reason, each call from Church End opens with the same trio — which fluid went in, how much, if the engine ran — before any quote. The replies turn a range into a straight quote.
You get that price on the phone, before anybody heads out, and you pay on the day, by card or by phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.
