AdBlue in the Diesel Tank in Redhills? Keep It Switched Off
AdBlue in the diesel tank? Then keep the motor off — and the ignition as well. AdBlue is urea dissolved in water. As it is water-based, it won't ignite and never combines with diesel; damage only starts once the pump begins drawing it. Caught before your motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the car is around Redhills. Nothing comes before ringing 0333 366 0103.
AdBlue in the diesel tank around Redhills: the first few minutes
Do:
- Take the keys out, so no one switches your ignition on.
- Near moving traffic? So put your hazards on.
- So you can tell us which fluid it was and about how much, save the till receipt or the empty bottle.
- Ring us from where you are. A postcode starting EX4 1, or the name of the closest street, brings our van to you without a search.
Not to do:
- Moving the car even a short way is no reason to start the motor.
- Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump.
- Don't top up with diesel to dilute it. AdBlue doesn't dilute in diesel; it separates out.
- Any driving at all is best avoided, even a short way down Redhills.
- Don't try to drain the car yourself at the roadside.
The staff working at any Redhills filling station — the Esso included — will usually help rolling it clear if you ask. On that drive, your car remains exactly as it is.
AdBlue in a diesel tank, and what it does there
AdBlue is made for the exhaust, not your engine. Its own reservoir keeps it, and from there it's sprayed into your exhaust, where it treats the gas. Nothing in an injection pump is designed for this liquid — and no part of that was meant to go that way.
Inside a diesel tank it acts very differently from fuel. It doesn't mix in. Heavier than diesel, it drops and pools below it — the very place the intake draws from. Once the system runs, the AdBlue is first to be pulled through. Until then it sits beneath the diesel, and that is how a car filled in St Thomas yesterday and never switched on remains the simple one, as long as no one turns the key.
Two kinds of harm come from there. What remains when the water evaporates is urea, which turns into crystals: they settle in tiny channels and clog filters. Worse, it eats at some metals in a fuel system, and keeps going till it is cleared out. A motor left standing in Redhills with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Water lubricates nothing. The injection pump and each injector need diesel flowing past them, so the water part harms them by itself.
Why is AdBlue in a diesel frequently the bigger fault?
Top up a diesel with petrol by mistake at the Sainsbury's, and the issue is thinned fuel. Damage only comes from driving on it. Mixed into your diesel and left inside the tank, it causes nothing.
The trouble with AdBlue in a diesel is a completely unsuitable liquid. It doesn't burn, so it can't simply be run through. Whether the car sits in Exeter or the heart of Redhills, turning it over "to see" does more harm in this case than nearly any other error, and the flush counts for more. Why: it will not remain mixed, and so diluting it is impossible; and crystals and corrosion outlast the next fill.
The good news is the same as with petrol. Clearing a tank is the easiest job on a fuel system, and without start-up, the AdBlue stays in it — wherever around Devon the vehicle sits.
How AdBlue ends up in a diesel tank in Redhills
Plenty of cars put the AdBlue cap alongside the diesel one, now and then behind a single flap, and in dim light the two can appear the same. No one means it. Usually it's not the filling station: someone picks up a container heading home and tips it in outside the house.
Mostly, it takes place in one of a couple of familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside St Gabriel's CofE Primary School. Close to Hadrian Drive, someone tips a bottle in at home in the evening. Otherwise, in dim light by The Thatched House, the car is topped up by a driver using that flap the first time.
It happens most in the vehicles motorists know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Leave it switched off: that's the first step to an identical slip, anywhere around Redhills or the remainder of Devon you are.
Redhills: started your engine with AdBlue in the diesel tank?
In that case, the AdBlue is no longer inside your tank. It's been sucked through your filter and the lines, and if the motor ran for any time, it has reached the high-pressure fuel pump and the injectors.
You may see the engine running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Barley Valley Nature Reserve or halfway across Redhills. Stop when it is safe. Switch off. Leave it off rather than restarting it to check. Each start pulls more of that through.
On the M5, under 5 miles from Redhills, the first junction is where to exit, and anywhere safe is where to park — not driving on.
How far it went counts. A couple of hundred yards across Redhills to the car park by Exwick Sports Hub is a very different job from a run towards Exeter, under 3 miles away, with the AdBlue reaching further into the system with every mile. About how far it had come is worth telling us.
Wherever the car came to a halt is where all of it gets done, even with more to flush after the engine has been started. When it is caught soon, long-term damage is very unusual.
What does an AdBlue drain on a diesel involve in Redhills?
A street by Steve Curley, a driveway, a layby or a filling station: anywhere your vehicle has stopped around Redhills, our technicians come to it. The work depends on three answers, which our engineers ask for first — what got in, the quantity, and whether the motor has turned over.
Then the tank is cleared where the vehicle waits, and so the contaminated fuel and the AdBlue come out together. What remains from AdBlue won't flush out by itself, so the whole system gets a full flush, which counts much more here than with petrol. Fresh diesel goes in once the filter is flushed — or replaced, if it needs to be — and after that your car is tested. If the engine has not run, the majority of jobs take about half an hour once our engineers arrive. Explosion-proof pumps make a busy forecourt safe to work on, and they're quiet enough to spare the neighbours at night.
The last step is to bleed the system on clean diesel. Whether it is a parking space by Exeter St Davids or a driveway in Redhills, that is where our technicians start the car and you head off. It's tested on new diesel to be sure it runs smoothly before we leave. The whole job is done where your car is, so it never has to be taken to a workshop. You get a VAT invoice and an engineer report after that, which is what insurers ask for.
About Redhills, briefly
Redhills is a suburban area located on the outskirts of Exeter in Devon, sitting alongside the River Exe at an elevation of around 79 metres. Redhills is characterized by its semi-detached housing stock and is situated near other local neighbourhoods such as Foxhayes and Exwick. Redhills has a population of approximately 5478 residents and is close to the city centre of Exeter, being only 1.1 miles away. Redhills is also near Nadderwater, another nearby suburban area.
AdBlue drains in Redhills and across Devon
Our vans that answer AdBlue call-outs in Redhills also cover the locations about it, Foxhayes, Exwick and Nadderwater among them, and most of Devon beyond, across the EX postcode area. If you're close to a border, or somewhere hard to explain, ring and ask instead of guessing.
A van that comes to you suits Redhills, a residential suburb: there's no need to take your car to us, since we empty it on the spot, on a driveway, a residential street, a car park or a filling station.
AdBlue in a diesel tank in Redhills: the cost of fixing it
There is no honest single quote, since the jobs are not the same. Three things change the cost: whether your engine has been running and for how long, how much AdBlue went in, and where the car is. That last one turns on whether a van can reach it safely, and an open drive is easier than a tight space behind St. Andrew.
Ahead of a figure, not afterwards, every enquiry from Redhills opens with the same three questions: the fuel, the quantity, plus if the engine ran. Given them, the range narrows to one firm number.
You hear that quote by phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront. While our engineer is on the way, dig out your policy: plenty cover misfuelling.
Redhills: still alongside your car?
Leaving the vehicle alone is, then, the best move you can do. Keys out, engine off, ignition off. Petrol in Diesel takes over the rest, across Redhills or anywhere within Devon, once you call 0333 366 0103 to say it's AdBlue, about what quantity, and whether it ran.
