AdBlue in the Diesel Tank in Lower Swainswick? Keep It Switched Off
AdBlue in the diesel tank? Then leave the engine off — and your ignition too. Chemically, AdBlue is just urea in water. Not like fuel, it neither ignites nor mixes, and nothing happens until your engine pulls it through. A drain and a thorough flush, done where the car is in Lower Swainswick, is generally all AdBlue in a diesel tank needs — if it's caught before your motor has been run. No step comes before ringing 0333 366 0103.
AdBlue in your diesel tank around Lower Swainswick: the first few minutes
Do these:
- So nobody can switch the ignition on, pull the keys out.
- Put the hazards on if you are anywhere close to moving traffic.
- Which fluid, and roughly how much volume? Save the bottle or the receipt, and our technicians can see.
- Ring us from where you are. A postcode starting BA1 7, or the name of the closest street, gets the van to you without a search.
Never do these:
- No starting the engine — not for a second, not to shift the vehicle.
- Many diesels power their fuel pump the moment the ignition comes on, so keep it off.
- AdBlue does not dilute in diesel — it separates out — so adding extra diesel will not thin it.
- Any driving at all is best avoided, including a short distance up Ferndale Road.
- Draining the tank yourself beside the road isn't one to try.
The attendants on duty at any Lower Swainswick forecourt — the Esso among them — will normally lend a hand pushing it clear if you ask. If you're on your own drive, leave it exactly where it is.
What AdBlue does in a diesel tank
The motor is not what AdBlue is made for; the exhaust is. Its own tank keeps it, and from there it's sprayed into your exhaust, where it treats the fumes. A fuel pump isn't designed to cope with it, and AdBlue was never intended to travel through one.
Poured in with your diesel, it keeps separate rather than blending — quite unlike fuel. The pickup takes fuel from the deepest part of that tank, and that is precisely where AdBlue settles: being heavier than diesel, it sinks. A motor filled on a driveway in Grosvenor overnight and not started since is the straightforward case. No pump has pulled the AdBlue up so far — though when the motor turns, that is what is pulled first, directly from the bottom of that tank.
It causes two kinds of harm from there. What remains once the water goes is urea, which forms crystals: they lodge in narrow passages and block filters. On top of that, it attacks some metals in a fuel system, and carries on till it's cleared out. If the AdBlue is in the pipework, waiting overnight in Lower Swainswick makes things worse. Inside the tank alone, time costs nothing. The water in it does damage of its own: the high-pressure fuel pump and the fuel injectors rely on diesel to lubricate them, and water gives them nothing.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Petrol pumped into a diesel on Sainsbury's's forecourt makes the fuel watery — that's the main fault. No harm is done as long as it stays put, blended into your diesel — only when the engine works on it.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. It does not burn, so it can't simply be run through. Crystals and corrosion stay through the following tankful, and AdBlue separates again out of the diesel, and so watering it won't work. That is why the flush counts so much, and trying your engine "to see" does more harm with AdBlue than almost any other slip — in Fairfield Park or the centre of Lower Swainswick equally.
As with petrol, there is good news. If the engine has not run, the AdBlue is still in your tank, and your tank is the simplest part of a fuel system to clear, wherever across Somerset the car is standing.
How AdBlue ends up in a diesel tank in Lower Swainswick
Plenty of motors place the AdBlue cap alongside the diesel cap, occasionally under a single flap, and after dark the two can look the same. Nobody intends it. Mostly it takes place with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
The ways it happens are few and familiar. A warning light comes on during the school run, and the top-up occurs in a hurry outside St Saviours Junior Church School. Near Bailbrook Grove, a driver tips a bottle in on the drive after work. One more version: darkness, a pub car park by Bladud's Head, and someone using that flap the first time.
It happens most in the motors drivers know least: a hire car, a new car, a company car, or the second car of a household with one diesel and one petrol. Same mistake, same first response — keep it off — wherever you happen to be around Lower Swainswick or the rest of Somerset.
Started the motor with AdBlue in the diesel tank around Lower Swainswick?
Then that tank is no longer where the AdBlue is. Through the fuel filter, along the pipework, and — given any running time — into the high-pressure pump and every injector: that is where it has gone.
Maybe returning from St Saviour's Little Park, or midway across Lower Swainswick, your engine may go lumpy, smoke, lose pace, flash your dash or cut out. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. More of it is pulled through with each start.
On the M4, under 10 miles from Lower Swainswick, the next junction is where to leave, and anywhere sensible is where to park — not driving on.
How far it went counts. A few hundred yards across Lower Swainswick to the car park by New Oriel Hall is a very different job from a run towards Bath, under 3 miles away, with the AdBlue reaching further into your system with each mile. Roughly how far had it come? Tell us.
Wherever your car came to a halt is where all of it gets done, even with more to rinse out once the engine has been started. Very seldom does it leave lasting damage if it's caught soon.
What emptying AdBlue from a diesel involves in Lower Swainswick
The vehicle remains where it is, whether that is a street near 21st Bath (Victoria Hall) Scout Group, a drive, a layby or a forecourt in Lower Swainswick, and our van travels to it. The job depends on three replies, which our technicians get before all else — what got in, the quantity, and if your motor has run.
Then the tank is emptied where your car stands, and so the tainted fuel and the AdBlue come out together. The fuel system is flushed thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. After that, the fuel filter: cleaned, or replaced when it has to be. Then fresh diesel, and then a check of the vehicle. If the engine hasn't run, the majority of jobs take about half an hour once our engineers are there. Quiet enough to use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.
Bleeding your system with clean diesel comes last. Starting the car comes next, and then you drive off from where the vehicle is parked, outside Bath Spa or on a driveway around Lower Swainswick. Our engineers make sure it runs correctly on new diesel before leaving. Since the job is done in its entirety where the vehicle is, a workshop never comes into it. You receive a VAT invoice and an engineer report afterwards, which is what insurers ask for.

Lower Swainswick: what AdBlue in a diesel tank costs to fix
Each job differs, so not one fixed price is fair. The price changes first with how long, if at all, your 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 van can reach it safely, which is simpler on an open drive than in a tight gap behind Larkhall United Reformed Church.
Which fluid was put in, how much, and if it ran: every Lower Swainswick enquiry begins by asking precisely those, before any quote, never after. Those replies turn a range into a straight price.
Priced by phone before the van sets out, the job is paid for that day — card or phone, no deposit. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
Lower Swainswick: still next to the vehicle?
In that case, touch nothing — that is the best step available. Motor off, keys out, ignition off. Petrol in Diesel handles the remainder, across Lower Swainswick or wherever within Somerset, after you phone 0333 366 0103 to say it was AdBlue, about what quantity, and if it ran.
