AdBlue in a Diesel Tank in Lympstone? Don't Start It
AdBlue in your diesel tank? Then leave your engine off — and the ignition too. AdBlue is urea dissolved in water. Being water-based, it will not burn and won't blend with diesel; damage only comes when the pump begins drawing it. A drain and a thorough flush, done where your car is around Lympstone, is generally all AdBlue in a diesel tank needs — if it is caught before your engine has run. Before anything, ring us on 0333 366 0103.
AdBlue in your diesel tank in Lympstone: the first few minutes
Do:
- Remove your keys, and that prevents someone switching the electrics on.
- Hazards on, if moving traffic is at all close.
- So you can give us which fluid it was and about how much, save the till receipt or the empty bottle.
- Give us a postcode starting EX8 5, or whichever street lies closest, and the van reaches you straight — so call from wherever you stand.
Never do these:
- Not even briefly, and not to roll the vehicle: the motor remains off.
- Your ignition stays off: on many diesels, switching it on is enough to run your pump.
- No more fuel on top. The AdBlue won't blend, and so it is pointless.
- Even a short stretch down The Strand is too far to drive the car.
- Don't try to drain it yourself by the roadside.
The attendants on duty at any Lympstone forecourt — the Esso among them — will usually lend a hand rolling it clear if you ask. On the drive, the vehicle stays exactly where it was left.
What does AdBlue do in a diesel tank?
Made for your exhaust, AdBlue has no business in your motor. It goes into its own tank and is sprayed into your exhaust gas to clean it. Not one side fits the other: urea does not belong in a pump, and an injection pump cannot take urea.
Inside a diesel tank it behaves really differently from fuel. It does not mix in. Heavier than diesel, it drops and collects underneath it — the same spot the pickup draws from. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Starcross last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of that tank, and nothing has drawn it in.
Two kinds of damage come from there. It eats at certain metals used in fuel systems, attacking any part it touches until it is removed from the system. And when the water goes, the urea forms crystals that block filters and lodge in narrow channels. Where the AdBlue is in the lines, waiting till morning around Lympstone makes it worse. Inside the tank only, waiting costs nothing. Water protects nothing. The injection pump and each injector need diesel running past them, so the water part harms them by itself.
AdBlue in a diesel: why it's commonly worse than petrol
Put petrol in a diesel at the Shell and you have an issue of thin fuel. Damage only comes from running on it. Mixed into the diesel and sitting inside your tank, it causes nothing.
AdBlue in a diesel is an issue of the wrong substance altogether. Because it doesn't burn, running it through is not an option. Deposits and corrosion stay after the following fill, and AdBlue splits back from your diesel, and so thinning it won't work. That is why the flush matters more, and trying the engine "to see" does more harm with AdBlue than nearly any other slip — in Brixington or the centre of Lympstone equally.
As with petrol, there's good news. If the engine has not run, the AdBlue is still inside that tank, and your tank is the easiest part of a fuel system to clear, wherever around Devon the car is standing.
How does AdBlue end up in a diesel tank around Lympstone?
Plenty of vehicles put the AdBlue filler beside the diesel one, occasionally under one flap, and in dim light the two may appear the same. No one intends it. A container bought while heading home and poured in at home, instead of at the filling station, is the typical route.
The ways it happens are few and familiar. Hurrying, outside Lympstone Church of England Primary School, after a warning light came on during the school run, a parent tops up the car. Near Underhill, a driver pours a container in at home after work. Another pattern: dim light, a pub car park by The Swan Inn, and a driver using that flap for the first time.
It comes up most in a rental, a new car, a company vehicle, or the other vehicle of a home with both fuels — the cars people use the least. Wherever you are around Lympstone or the rest of Devon, it's the same slip and the same first answer: leave the vehicle off.
Started your engine with AdBlue in the diesel tank in Lympstone?
The AdBlue has left that tank, then. Through your filter, along the pipework, and — given any running time — into the high-pressure pump and every injector: that is how far it travels.
Expect lumpy running, smoke, lost power, warnings on the dash, or a stall — returning from Cliff Field, perhaps, or part way across Lympstone. Stop as soon as it is safe, switch off, and do not restart the car to check. More of that is pulled through with each start.
On the M5, under 5 miles from Lympstone, the next junction is where to exit, and anywhere sensible is where to park — not driving on.
How far it went matters. A few hundred yards across Lympstone to the car park by Peter's Tower is a very different job from a run towards Exeter, under 10 miles away, with the AdBlue reaching further into your system with each mile. Approximately how far had it come? Tell us.
Once the engine has been run, the flush takes in more, and all of it is done where the vehicle has ended up. Very rarely does it leave permanent damage if it is spotted quickly.
Lympstone: how AdBlue is emptied from a diesel
The vehicle remains where it is, whether that's a street beside Primitive Methodist School, a driveway, a lay-by or a forecourt in Lympstone, and the van travels to it. Three replies decide the work, and so before anything else our engineers ask what went in, roughly what quantity, and whether the motor has run.
The polluted diesel and the urea leave as one when your tank is drained, right there. With AdBlue, more so than with petrol, flushing counts: the fuel system is flushed all the way through because what remains won't flush out by itself. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If the motor hasn't run, the majority of jobs take about half an hour once our technicians arrive. Quiet enough for use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.
Lastly, your system is primed with clean diesel. Whether it's a parking space by Lympstone Village or a driveway around Lympstone, that is where we start the car and you set off. It is tested on new diesel to confirm it runs smoothly before we head off. Since the job is done in its entirety where the car is, a workshop never comes into it. You get a VAT invoice and an engineer report later, which is what insurers ask for.
About Lympstone, for a moment
Lympstone is a small coastal village in Devon, situated near the Exe Estuary and close to the cities of Exeter and Powderham. Lympstone has a low elevation of around 3 metres, reflecting its coastal setting. Lympstone is characterised by its predominantly detached housing stock, with the village being home to around 579 residents. Lympstone is located near several other small villages, including Powderham, Hulham, and Exton.
AdBlue drains across Lympstone and Devon
AdBlue call-outs around Lympstone go to vans that cover the places around it — Powderham, Hulham plus Exton — and most of Devon further out, throughout EX postcodes. Assuming doesn't help close to a border or somewhere tricky to describe; ring and check.
Lympstone is a coastal village, and an on-site drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be shifted to us.
What AdBlue in a diesel tank costs to put right in Lympstone
Not one single figure could be honest, because each job differs. Three things change the cost: whether the motor has been running and for how long, how much AdBlue was put in, and where the car is. That last one comes down to whether a technician can get to it safely, and an open driveway is easier than a tight space behind Lympstone Methodist Chapel.
What got in, what quantity, and if it ran: every Lympstone enquiry begins by asking precisely those, before a quote, never afterwards. With them, the range shrinks to a single firm number.
Quoted by phone before the engineer heads out, the job is paid for on the day — card or phone, nothing in advance. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
In Lympstone and still beside the car?
Right now, the best thing to do with your vehicle is to leave it. Keys out; engine and ignition off. Phone 0333 366 0103: AdBlue, roughly how much, and if it ran is everything our engineers need. Petrol in Diesel takes over the remainder across Devon, Lympstone included.
