AdBlue in a Diesel Tank in Woolwich? Don't Start It
AdBlue in the diesel tank? Then keep your motor off — and your ignition too. AdBlue is urea dissolved in water. Being water-based, it won't burn and won't blend with diesel; damage just comes once your pump starts drawing it. If your engine hasn't run yet, AdBlue in a diesel tank is normally emptied and carefully cleaned where the vehicle sits in Woolwich. Call 0333 366 0103 before you do anything else.
AdBlue in the diesel tank around Woolwich: the first few minutes
Do these:
- Take the keys out, and so nobody switches your ignition on.
- Close to moving traffic? So put the hazard lights on.
- Which fluid, and roughly what volume? Save the bottle or the till receipt, and our technicians can know.
- Call right where you are. Quote a SE18 6 postcode or the closest street sign, and nobody has to hunt for you.
Do not:
- Do not start your engine, even for a moment to shift the car.
- Switching the key to ignition by itself sets your pump running on many diesels. Skip it.
- No extra fuel added. The AdBlue won't mix, so it's pointless.
- Do not drive the vehicle anywhere, not even a short way down Market Street.
- Draining the tank yourself beside the road is not worth trying.
On a forecourt around Woolwich, whether it's the Harvest Energy or another one, ask the staff to help you roll your car away from the petrol pump. If you are on your own drive, leave the vehicle just where it stands.
AdBlue in a diesel tank, and what it does there
Meant for your exhaust, AdBlue has no place in the motor. From a separate tank it goes directly to the exhaust, treating what the engine emits. Not one side fits the other: urea does not belong in a pump, and a pump cannot take urea.
Inside a diesel tank it behaves very differently from fuel. It does not mix in. Denser than diesel, it drops and pools underneath it — the same spot the pickup draws from. A vehicle filled on a drive in West Thamesmead overnight and not started since is the simple case. No pump has sucked the AdBlue up yet — though once the engine turns, that's what is pulled first, straight from the bottom of the tank.
From there it causes two kinds of harm. What remains once the water goes is urea, which forms crystals: they settle in narrow passages and clog filters. Worse, it attacks certain metals in a fuel system, and carries on until it is flushed out. If the AdBlue is in the pipework, leaving it till morning in Woolwich makes things worse. In the tank only, waiting does nothing. Then there is the water: it brings no protection to the parts that rely on it the most — the injection pump and every injector.
Why AdBlue in a diesel is regularly more serious than petrol
Petrol put into a diesel on Shell's forecourt leaves the fuel watery — that's the main fault. Harm just comes from running on it. Blended into the diesel and left in that tank, it causes none.
With AdBlue in a diesel, the fluid as such is simply the wrong one. It doesn't burn, so it can't simply be run through. Nor can it be watered down, since it separates again — and the next tankful will not rinse away crystals or corrosion. So the flush counts more with AdBlue, and trying the engine "to see", in the centre of Woolwich or out in Charlton, does more harm than nearly any other slip.
With AdBlue, the good news is no different from petrol. Not run? Then the AdBlue sits only in that tank, the simplest bit of the whole system to empty, anywhere the vehicle has stopped across Greater London.
How does AdBlue end up in a diesel tank in Woolwich?
Nobody means to do it. The AdBlue filler on plenty of motors waits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.
It tends to occur in a couple of familiar ways. A warning light comes on during the school run, and the top-up takes place in a hurry outside Mulgrave Primary School. Close to Monk Street, someone tips a bottle in on that drive in the evening. Else, after dark outside Earl of Chatham, your vehicle gets topped up by a driver using that flap the first time.
Rented cars, new motors, fleet vehicles, or the spare vehicle in a family with both fuels: the least familiar cars get it the most. Same slip, an identical first response — keep it switched off — anywhere you happen to be around Woolwich or the rest of Greater London.
Already started the engine with AdBlue in the diesel tank in Woolwich?
Then the AdBlue has left that tank. Via the fuel filter, through the lines, and — with any running time — on to the injection pump and each injector: that is how far it travels.
Expect rough running, exhaust smoke, lost power, lights on your dash, or a cut-out — coming back from General Gordon Square, perhaps, or midway across Woolwich. Stop when safe. Switch off. Leave the vehicle off rather than testing it again. Each start pulls more of it through.
If you were on the M11, under 10 miles from Woolwich, come off at the next exit and stop somewhere sensible rather than pressing on.
Mileage matters: each mile carries the AdBlue further into the system, so driving towards London, under 10 miles away, gives a far bigger job than crossing Woolwich to the car park by Magistrates Court. Tell us about how far it had come.
There is more to flush once the engine has run, and we do all of it where the car has stopped. Noticed early, it very rarely leaves lasting damage.
What emptying AdBlue from a diesel involves in Woolwich
Our engineers come to your car, wherever it has stopped in Woolwich: a side street close to Woolwich Town Hall, a drive, a lay-by or a forecourt. What got in, roughly the quantity, plus whether your motor has been run: we check first, since those decide the job.
The contaminated diesel and the urea come out together after your tank is drained, right there. Residue from AdBlue won't wash out by itself, and so the whole system gets a careful flush, which matters much more with urea than with petrol. Clean diesel goes in after your filter is flushed — or swapped, if it needs to be — and after that your car is tested. Not run? Then expect about half an hour once we are there for most jobs. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.
Priming the fuel system with clean diesel comes last. After that we fire it up and you drive off, whether from a parking space outside Woolwich Arsenal or a driveway around Woolwich. The check before our engineers leave is that it runs correctly on new diesel. The entire job is done where the car is, so it never needs to be taken to a workshop. You receive a VAT invoice and an engineer report after that, which is what insurers ask for.

AdBlue drains across Greater London, Woolwich included
Over the SE postcode area, the teams taking AdBlue jobs around Woolwich serve much of Greater London as well, Royal Arsenal West, North Woolwich and Plumstead included. Near a border, or anywhere awkward to explain? Asking beats guessing, so ring.
A mobile service suits Woolwich, a small village: there's no need to bring the car to us, because we drain it on the spot, on a driveway, a side street, a parking area or a filling station.
What AdBlue in a diesel tank costs to put right around Woolwich
Because the callouts differ, a single price wouldn't be honest. Three things shift the price: whether the engine has been running and for how long, how much AdBlue got in, and where your car is. That last one turns on whether a van can get to it safely, and an open drive is easier than a tight spot behind Greenwich Council (Woolwich Centre).
What went in, how much, plus whether it ran: every Woolwich enquiry begins by asking precisely those, before any quote, not after. Once those are known, a range turns into a single fixed figure.
You get that quote by phone, before anyone heads out, and you pay on the day, by card or over the phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.
