Don't Start It: AdBlue in a Diesel Tank in Marldon
With AdBlue in the diesel tank, your ignition stays off and so does the engine. In plain terms, AdBlue is just urea in water. Not like fuel, it neither burns nor blends, and no harm starts until the motor pulls it through. Caught before the engine has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around Marldon. Before you do anything else, ring 0333 366 0103.
AdBlue in your diesel tank around Marldon: the first few minutes
Do these:
- Pocket your keys, which stops anyone turning the power on.
- Near moving traffic? So put the hazards on.
- Which fluid, and roughly how much quantity? Save the bottle or the till receipt, and our technicians can see.
- The van locates you fastest with a postcode starting TQ3 1, or simply the name of a street close by, and so phone from the spot.
Not to do:
- Do not start your motor, even for a moment to shift the car.
- The ignition stays off: on lots of diesels, turning it on is enough to run your pump.
- No extra fuel on top. The AdBlue won't blend, and so it is wasted.
- Keep the car where it is rather than driving it anywhere, even a short way down Peters Crescent.
- No emptying it yourself, at all, at the roadside.
Get the attendants to help you roll the vehicle away from the pumps if you're at a forecourt around Marldon, whether it is the Harvest Energy or elsewhere. If you're on your own drive, leave the vehicle exactly where it stands.
AdBlue in a diesel tank: what it does
Not the motor but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into your exhaust gas to fresh it. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Inside a diesel tank it behaves 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 sucks fuel from. The first thing the system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Preston last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has sucked it in.
From there it does two kinds of harm. What is left once the water goes is urea, which forms crystals: they settle in narrow channels and block filters. On top of that, it eats at some metals in the fuel system, and keeps going until it's cleared out. By daybreak, a vehicle parked around Marldon with AdBlue in its lines gets worse; where it is only inside the tank, nothing changes. And there's the water: it offers no lubrication to the parts that rely on it most — the injection pump and every injector.
Why is AdBlue in a diesel commonly the bigger issue?
A problem of thinned fuel is what you get after filling a diesel with petrol at the Texaco. Damage only comes from driving on it. Blended into your diesel and sitting inside the tank, it causes nothing.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. It does not burn, and so it cannot just be run through. Deposits and corrosion remain after the following fill, and AdBlue separates again from your diesel, so watering it won't help. Hence the flush counts so much, and trying your engine "to see" does more harm with AdBlue than almost any other slip — in Higher Blagdon or the heart of Marldon alike.
With AdBlue, the good news is no distinct from petrol. If the motor has not run, the AdBlue is still inside the tank, and the tank is the easiest part of a fuel system to clear, wherever around Devon the car is standing.
Marldon: how AdBlue ends up in a diesel tank
After dark, two caps together — the AdBlue cap and the diesel cap, occasionally behind one flap — may look the same. No one means it; plenty of layouts invite it. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the forecourt.
The ways it occurs are few and familiar. A warning light comes on during the school run, and the top-up occurs in a hurry outside Marldon Church of England Primary School. A driver pours the container in outside their house, just off Meadow Park, as the day ends. Otherwise, after dark by Church House Inn, your car is refilled by someone opening that flap the first time.
It occurs most in the vehicles 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 you are in Marldon or the rest of Devon, it is the same error and the same first answer: leave the car off.
AdBlue in the diesel tank in Marldon, and the motor started?
Then that tank is no longer where the AdBlue is. Via the filter, through the lines, and — given any running — into the injection pump and every injector: that's where it travels.
Watch for lumpy running, smoke, lost power, lights on the dash, or a cut-out — coming back from Jubilee Meadow, perhaps, or midway across Marldon. No restarting to test: stop once it is safe, then switch it off. Each start pulls more of that through.
On the M5, under 25 miles from Marldon, the first junction is where to exit, and anywhere safe is where to park — not carrying on.
A quick hop across Marldon to the car park by St. John the Baptist is one thing; driving for Exeter, under 25 miles away, is another, because each mile carries the AdBlue further in. So mileage counts. Approximately how far had it come? Tell us.
Once the motor has been started, the flush takes in more, and all of it is done where your car has ended up. Permanent damage is very rare if it is caught quickly.
What does an AdBlue drain on a diesel involve around Marldon?
A road by Occombe Farm, a drive, a lay-by or a forecourt: anywhere your vehicle has come to rest in Marldon, our engineers come to it. The work depends on three replies, which our technicians ask for first — which fluid went in, the quantity, and whether the engine has run.
Then your tank is cleared where the car waits, so the contaminated fuel and the AdBlue come out together. The fuel system is purged thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. After that, the filter: cleaned, or replaced when it has to be. Then fresh diesel, then a check of your vehicle. Most of these jobs are a half-hour job once our technicians get there, if your engine hasn't run. Quiet enough for use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.
The last step is to bleed your system on new diesel. Firing it up comes next, and then you set off from where the vehicle is parked, by Paignton or on a drive in Marldon. The test before our engineers head off is that it runs properly on clean diesel. The entire job is done where your car is, so it never has to be taken to a garage. Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

AdBlue in a diesel tank around Marldon: the cost of fixing it
There is no fair single quote, because the jobs are not the same. Three things shift the cost: whether your engine has run and for how long, how much AdBlue got in, and where the vehicle is. That last one turns on whether our van can get to it safely, and an open driveway is easier than a tight spot behind Compton Castle.
With that in mind, every enquiry from Marldon begins with the same trio — what got in, what quantity, whether the engine ran — before a figure. Once those are answered, a range becomes a single firm number.
You hear that price on the phone, before anybody sets off, and you pay on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
