AdBlue in the Diesel Tank in St Martins? Keep It Switched Off
AdBlue in the diesel tank? Then keep the motor off — and your ignition too. Chemically, AdBlue is simply urea in water. Being water-based, it will not burn and never combines with diesel; trouble only comes once your pump starts pulling it. A drain and a thorough flush, done where your car is in St Martins, is usually what AdBlue in a diesel tank takes — if it's caught before your motor has been run. Before you do anything else, ring 0333 366 0103.
AdBlue in your diesel tank in St Martins: the first few minutes
Things to do:
- Pull the keys out, so no one switches your ignition on.
- Close to moving traffic? So put the hazard lights on.
- Which fluid, and roughly how much amount? Hang on to the bottle or the receipt, and our technicians can know.
- Give us a postcode starting CF83 1, or whatever street is nearest, and our van finds you straight — so ring wherever you stand.
Never do these:
- Don't start your engine, even for a moment to move your car.
- The ignition remains off: on many diesels, turning it on is enough to run the fuel pump.
- Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
- Any driving at all is to be avoided, including a short distance up Redbrook Court.
- No draining it yourself, at all, at the roadside.
The staff working at any St Martins forecourt — the Texaco among them — will usually help pushing it clear if you ask. Parked on your own driveway? Then it stays exactly as it is.
AdBlue in a diesel tank, and what it does there
The motor isn't what AdBlue is made for; the exhaust is. It goes into its own tank and is sprayed into the exhaust gas to clean it. No part inside an injection pump is designed for this liquid — and no part of that was meant to travel through one.
Inside a diesel tank it acts really differently from fuel. It does not mix in. The pickup sucks fuel from the lowest part of the tank, and that is precisely where AdBlue settles: as it is denser than diesel, it sinks. A motor filled on a driveway in Caerphilly yesterday evening and not started since counts as the simple one. No pump has sucked the AdBlue up yet — though once your motor turns, that is what goes first, straight from the bottom of your tank.
From there it does two kinds of harm. What is left when the water goes is urea, which forms crystals: they lodge in narrow passages and clog filters. Worse, it eats at some metals in the fuel system, and carries on till it's flushed out. If the AdBlue has reached the lines, waiting till morning in St Martins leaves things worse. In your tank alone, waiting costs nothing. Diesel lubricates the high-pressure pump and each injector as it flows; water gives no lubrication, and that is a second form of harm.
AdBlue in a diesel: why it's commonly worse than petrol
Put petrol in a diesel at the Morrisons and you have a fault of thin fuel. It mixes with your diesel, and while it's in the tank it causes no damage; the damage comes from running the motor on it.
AdBlue in a diesel is a problem of the wrong substance altogether. Since it does not burn, running it through isn't an option. Deposits and corrosion remain after the following tankful, and AdBlue separates again out of your diesel, and so thinning it can't help. Hence the flush matters so much, and turning the key "to see" does more harm with AdBlue than almost any other mistake — in Glenfield Estate or the heart of St Martins alike.
The same good news holds as with petrol. Emptying a tank is the easiest part on any fuel system, and without start-up, the AdBlue stays in there — wherever across Caerphilly your car sits.
AdBlue in a diesel tank in St Martins: how it ends up there
No one means to do it. The AdBlue filler on many motors sits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. It mostly happens at home, from a bottle grabbed on the journey home, not at the forecourt.
Usually, it takes place in one of a couple of familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside the local primary school the top-up is rushed. Close to St Martin's Road, a driver tips a container in at home after work. Or someone unfamiliar with that flap refills the vehicle after dark, parked in the car park outside The Malcolm Uphill.
The least familiar vehicles see it the most — rentals, new ones, fleet cars, and the spare vehicle of a family with one of each fuels. Keep it switched off: that is the first step to the same slip, wherever in St Martins or the rest of Caerphilly you are.
St Martins: started the motor with AdBlue in the diesel tank?
In that case, the AdBlue is no longer inside the tank. Via the filter, through the lines, and — given any running — on to the injection pump and every injector: that is how far it travels.
Watch for lumpy running, exhaust smoke, lost power, warnings on the dash, or a stall — returning from Caerphilly Golf Club, perhaps, or part way across St Martins. When safe, stop and turn it off — with no turning it on again to see. Every start pulls more of that through.
If you were on the M4, under 3 miles from St Martins, come off at the next junction and stop somewhere safe instead of pressing on.
Distance matters: each mile pushes the AdBlue deeper in, and so heading towards Cardiff, under 10 miles away, gives a far bigger job than hopping across St Martins to the car park by St Martin's Church. Let us know roughly how far it had come.
We do all of the cleaning where the car has stopped, and once the engine has run there is more of it. Permanent damage is very uncommon when it is noticed soon.
St Martins: how AdBlue is drained from a diesel
A street beside Wesley Methodist Church, a driveway, a lay-by or a forecourt: anywhere the car has come to rest around St Martins, our engineers come to it. Three answers shape the work, and so before anything else we ask which fluid was put in, about what quantity, and whether your motor has run.
Next, draining that tank right there removes the polluted diesel along with the AdBlue in one go. The system is rinsed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. Fresh diesel goes in once the filter is flushed — or replaced, when it needs to be — and then your car is tested. Engine not run? In that case expect about half an hour on site for most jobs. Quiet enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.
Lastly, the fuel system is primed with fresh diesel. You drive off as soon as our engineers have fired it up, and it makes no difference whether your car is on a drive around St Martins or in a bay by Caerphilly. We check it runs properly on clean diesel before we go. Because the job is done in full where the vehicle is, a garage never comes into it. Your insurer will want an engineer's report and the VAT invoice — each handed over once the job is done.

AdBlue drains across Caerphilly, St Martins included
Denscombe, Bryngwyn and Bondfield Park are among the towns around St Martins that the same vans serve, together with most of Caerphilly beyond, throughout the CF postcode area. Close to a boundary, or somewhere tricky to explain? Checking is better than guessing, so ring.
A van that comes to you fits St Martins, a residential suburb: you have no need to bring the vehicle to us, since our engineers drain it there, on a driveway, a side street, a car park or a filling station.
What does AdBlue in a diesel tank cost to sort out around St Martins?
No single price could be honest, since each job differs. The cost moves first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where the car is and whether a van can reach it safely, which is simpler on an open driveway than in a tight spot behind Caerphilly Miners' Centre for the Community.
With that reason, each enquiry from St Martins opens by asking the identical trio — which fluid was put in, what quantity, whether it ran — before a quote. Those replies shrink a range down to one number.
Priced on the call before the engineer heads out, it is paid for on the day — card or phone, nothing in advance. While our engineer is on the way, dig out your insurance: many cover misfuelling.
