AdBlue in a Diesel Tank in St Mary Cray? Don't Start It
AdBlue in the diesel tank? Then keep your engine off — and the ignition as well. Water with urea dissolved in it: that's AdBlue. It does not burn, it doesn't mix with diesel, and the harm it does starts when the fuel system draws it in. In St Mary Cray, AdBlue in a diesel tank caught before your engine runs usually comes down to a drain and a thorough flush, just where your car is. Ring 0333 366 0103 before you do anything else.
AdBlue in the diesel tank around St Mary Cray: the first few minutes
To do:
- Pocket your keys, and that stops someone switching the power on.
- If you're at all near moving traffic, put your hazards on.
- Keep your receipt or the empty bottle, so you can tell us what went in and roughly how much.
- Tell us a postcode starting BR5 4, or whichever street lies nearest, and our van reaches you straight — so ring wherever you stand.
Things not to do:
- Moving the car even a few yards is no reason to start your motor.
- The ignition stays off: on lots of diesels, switching it on is enough to run the pump.
- Pouring in extra diesel doesn't work: AdBlue separates out instead of thinning.
- Keep the vehicle where it is rather than driving it anywhere, even a short stretch along Lower Road.
- Draining your tank yourself beside the road is not one to try.
The staff working at any St Mary Cray forecourt — the Texaco among them — will normally lend a hand rolling it aside if you ask. At home, the vehicle stays just as it is.
AdBlue in a diesel tank: what it does
AdBlue is made for the exhaust, not the motor. Kept in a dedicated tank, it's injected into the exhaust stream to treat the gases. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Fuel mixes; AdBlue, once tipped in, won't. Its behaviour is nothing like diesel's. Denser than diesel, it drops and pools underneath it — the same place the intake sucks from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Orpington last night, and hasn't been started since, is still the easy case: the AdBlue is lying at the bottom of that tank, and nothing has drawn it in.
From there it causes two kinds of harm. It eats at certain metals found in fuel components, attacking any part it reaches until it is cleared completely. And when the water evaporates, the urea turns into crystals that block filters and settle in narrow passages. If the AdBlue is in the pipework, waiting till morning around St Mary Cray makes it worse. Inside your tank only, time costs nothing. Then there's the water: it offers no lubrication to the parts that need it the most — the injection pump and every injector.
Why is AdBlue in a diesel regularly the bigger fault?
Petrol put into a diesel on Tesco Express's forecourt leaves the fuel thin — that's the whole problem. It mixes with your diesel, and while it is in that tank it does no damage; the harm comes from running your engine on it.
With AdBlue in a diesel, the fluid as such is simply the wrong one. Since it doesn't burn, running it through is not an option. Whether the vehicle is in Kevingtown or the centre of St Mary Cray, firing it up "to see" costs more in this case than almost any other mistake, and the flush matters more. Why: it won't stay blended, so watering it down fails; and crystals and corrosion survive the following tankful.
The same good news holds as with petrol. Emptying a tank is the easiest job on a fuel system, and with no start-up, the AdBlue remains in there — wherever across Greater London the car has stopped.
How does AdBlue end up in a diesel tank in St Mary Cray?
Plenty of motors place the AdBlue cap beside the diesel one, now and then under a single flap, and after dark the two can appear the same. No one intends it. A container bought while heading home and poured in outside the house, rather than at the forecourt, is the usual route.
Usually, it occurs in one of a couple of familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside St. Mary Cray Primary Academy. After work, a bottle is tipped in on a driveway close to Wellington Road. One more version: dim light, the car park by White Swan, and a driver using that flap the first time.
Rented cars, new vehicles, company vehicles, or the spare vehicle in a family with one of each: the least familiar cars see it most. An identical mistake, an identical first step — keep it switched off — wherever you are in St Mary Cray or the remainder of Greater London.
Already started the engine with AdBlue in the diesel tank around St Mary Cray?
Then the AdBlue has left your tank. Your filter and lines have had it sucked through, and some running time carries it on to the injection pump and every injector.
Rough running, smoke, dropping power, dashboard warnings or cutting out: any might appear, perhaps part way across St Mary Cray or returning from Riverside gardens. Pull over when safe. Switch off. Leave it off rather than restarting it to check. With each start, more of that is pulled through.
On the M25, under 3 miles from St Mary Cray, the next junction is where to leave, and anywhere sensible is where to park — not carrying on.
Mileage counts: each mile carries the AdBlue deeper into the system, so heading for London, under 15 miles away, makes a much bigger job than hopping across St Mary Cray to the car park by The Salvation Army. Tell us roughly how far it had come.
Wherever the car came to a stop is where all of it gets done, even with more to clean out once the motor has been running. If it's spotted soon, permanent damage is very uncommon.
St Mary Cray: how AdBlue is emptied from a diesel
A road by St Andrews, a driveway, a layby or a filling station: anywhere the car has stopped around St Mary Cray, our engineers come to it. The job depends on three replies, which we ask for before all else — which fluid was put in, the quantity, and if your engine has turned over.
Right there, that tank is then drained, and both the contaminated diesel and the urea come out as one. Residue from AdBlue will not wash away by itself, and so the whole system gets a full flush, which matters much more with urea than for petrol. A test of the car comes last, once clean diesel goes in and your filter is flushed or, where needed, replaced. If your motor has not run, the majority of jobs take about half an hour once our engineers arrive. Quiet enough for use outside a house at night, and fine on a working forecourt, our pumps are explosion-proof.
Bleeding your system with fresh diesel comes last. Whether it's a parking space at the nearest station or a driveway in St Mary Cray, that is where our technicians start it and you set off. The test before our engineers head off is that it runs properly on fresh diesel. Our engineers do it all wherever the vehicle has stopped, and it never has to go to a garage. Your insurer will want an engineer's report and your VAT invoice — both yours once this job is done.

What AdBlue in a diesel tank costs to put right in St Mary Cray
Not one single price could be fair, because every job is different. What moves the price is, first of all, whether your engine has been running and for how long; then how much AdBlue went in; and after that where the car is and whether our van can reach it safely, which is simpler on an open driveway than in a tight spot behind Roman Bath House.
For that in mind, every enquiry from St Mary Cray begins with the same trio — which fluid got in, what quantity, whether the engine ran — before any quote. Those replies turn a range into a straight price.
You hear that price by phone, before anyone sets off, and you pay on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
