AdBlue in the Diesel Tank in Crayford? Keep It Switched Off
Engine off, ignition off: that is how you start if AdBlue has got into the diesel tank. Water with urea mixed in it: that's AdBlue. Being water-based, it will not burn and never combines with diesel; damage just comes when the pump starts drawing it. Caught before the engine has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is in Crayford. No step comes before ringing 0333 366 0103.
AdBlue in the diesel tank around Crayford: the first few minutes
To do:
- Take the keys out, so nobody switches your ignition on.
- Put the hazards on if you are at all close to moving traffic.
- Hold on to your receipt or the empty bottle, so you can tell us what was put in and about how much.
- Our van finds you fastest with a postcode starting DA1 4, or simply the name of a street close by, so phone from the spot.
Never do these:
- Moving the car just a few yards is no reason to fire up the engine.
- Your ignition remains off: on lots of diesels, switching it on is enough to run the pump.
- AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel won't weaken it.
- Keep the car where it is rather than driving it anywhere, even a short way down Bexley Lane.
- No emptying it yourself, at all, at the verge.
Moving the vehicle away from the pumps is a job for staff to help with, wherever Crayford forecourt you are on, the Sainsbury's included. On your own drive, do not move it at all.
AdBlue in a diesel tank, and what it does there
The engine is not what AdBlue is made for; your exhaust is. 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 built to handle it.
Inside a diesel tank it acts very differently from fuel. It doesn't mix in. Heavier than diesel, it drops and collects below it — the same spot the pickup draws from. A motor filled on a drive in North End overnight and left unstarted is the straightforward one. No pump has pulled the AdBlue up so far — though once the motor turns, that's what is pulled first, directly from the bottom of the tank.
It causes two kinds of harm from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, and so it keeps labouring on the components it reaches for as long as it remains there. A motor left sitting around Crayford with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. The water in it causes damage of its own: the high-pressure fuel pump and the fuel injectors rely on diesel to lubricate them, and water gives them nothing.
Why AdBlue in a diesel is commonly more major than petrol
An issue of thinned fuel is what you end up with after filling a diesel with petrol at the Shell. Damage only comes from running on it. Blended into the diesel and left in your tank, it causes nothing.
The issue with AdBlue in a diesel is a totally unsuitable liquid. Not burning, it can't just be run through. Whether your vehicle is in Colyers or the heart of Crayford, turning it over "to see" costs more in this case than almost any other slip, and the flush counts for more. Why: it will not stay blended, so diluting it fails; and deposits and corrosion survive the following fill.
The good news is the same as with petrol. Never run? Then the AdBlue sits just inside your tank, the simplest bit of the whole system to empty, anywhere your car has stopped around Greater London.
AdBlue in a diesel tank in Crayford: how it ends up there
Nobody means to do it. The AdBlue filler on plenty of cars rests right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Mostly it's never the filling station: a driver buys a container heading home and tips it in outside the house.
Usually, it happens in one of a couple of familiar ways. Midway through the drop-off, the dashboard warns, and outside St Paulinus Church of England Primary School the top-up is rushed. A bottle is poured in at the end of the day on a drive just off Green Place. Else, in dim light outside The Crayford Arms, the car gets refilled by someone opening that flap the first time.
Rented cars, brand-new motors, company vehicles, or the spare car in a family with both fuels: the least familiar vehicles get it most. Wherever across Greater London, Crayford as well, the slip does not change, and neither does the first step: keep it off.
Already started the motor with AdBlue in your diesel tank in Crayford?
The AdBlue has left that tank, then. The fuel filter and lines have had it pulled through, and some running time carries it on to the high-pressure pump and each injector.
Perhaps coming back from Waterside Gardens, or midway across Crayford, the engine may go rough, smoke, drop power, light up your dash or cut out. Stop as soon as it is safe, switch off, and do not restart it to check. With each start, more of it is pulled through.
If you were on the M25, under 5 miles from Crayford, come off at the next exit and stop somewhere sensible rather than pressing on.
How far it went counts. A few hundred yards across Crayford to the car park by Masjid Abu Bakar is a very different job from a run towards London, under 15 miles away, with the AdBlue reaching further into the fuel system with every mile. Approximately how far had it come? Tell us.
There is more to flush once your engine has been run, and we do all of it where your car has stopped. Noticed quickly, it very rarely leaves long-term damage.
What does an AdBlue drain on a diesel involve in Crayford?
Wherever it has come to rest in Crayford — a forecourt, a lay-by, a driveway, a street beside The City of God — our van comes to the car. Which fluid was put in, about the quantity, and whether your motor has turned over: we check before all else, since those shape the job.
On the spot, your tank is then drained, and all of the polluted diesel and the urea leave at once. A careful flush matters much more with AdBlue than after petrol, because what remains will not wash out by itself. After that, the filter: flushed, or replaced if it has to be. Then clean diesel, and then a test of your vehicle. If the motor has not run, the majority of jobs take about half an hour once we arrive. The equipment is explosion-proof, and so a live forecourt is no issue, and it's hushed enough for a residential street after dark.
Finally, the fuel system is bled with fresh diesel. At that point our technicians fire it up and you set off, whether from a parking space at the nearest station or a drive in Crayford. Before leaving, we make sure it's running correctly with fresh diesel in. No garage is required at any point, with the entire job done on the spot. You get a VAT invoice and an engineer report later on, which is what insurers want.

Crayford and Greater London: AdBlue drains across the area
The vans that answer AdBlue calls around Crayford also cover the spots round it, Barnes Cray, Barnehurst and Bowmans among them, and most of Greater London beyond, across the DA postcode area. If you're near a boundary, or somewhere hard to describe, ring and ask instead of assuming.
No moving is needed. In Crayford, a small village, a mobile service fits: your vehicle is emptied on the spot, be it in a drive, a residential street, a parking area or a filling station.
What does AdBlue in a diesel tank cost to sort out in Crayford?
There's no fair single quote, since the jobs aren't the same. Whether the motor has been running, and for how long, comes first in what moves the cost. How much AdBlue got in comes next, and then the position of the vehicle, because an open driveway is simpler for a technician to get to safely than a tight spot behind Crayford Baptist Church.
For that in mind, every call from Crayford begins with the same trio — what got in, what quantity, if the engine ran — ahead of a figure. Those answers shrink a range down to one figure.
The quote is quoted on the call, before anyone leaves; payment happens on the day, by card or by phone, with nothing upfront. As the van is travelling, dig out your insurance: many include misfuelling.
In Crayford and still next to the vehicle?
Then, the most helpful thing to do with your car is to leave it. Keys out; engine and ignition off. Say it's AdBlue, about how big an amount, and whether it ran, on 0333 366 0103. After that Petrol in Diesel handles it, in Crayford or wherever within Greater London.
