Don't Start It: AdBlue in a Diesel Tank in Balerno
AdBlue in your diesel tank? Then keep the engine off — and the ignition as well. Water with urea dissolved in it: that's AdBlue. Unlike fuel, it neither burns nor blends, and no harm happens until your motor pulls it through. If the motor has not run yet, AdBlue in a diesel tank is normally drained and carefully rinsed where your car sits around Balerno. No step comes before ringing 0333 366 0103.
Your next steps right now, Balerno: AdBlue in the diesel tank
Do:
- Pull your keys out, so nobody switches the ignition on.
- Put the hazard lights on if you are anywhere near moving traffic.
- The empty bottle or the receipt shows us the fluid and the amount, and so do not throw it out.
- Tell us a postcode starting EH14 7, or whatever street lies closest, and the van reaches you straight — so ring wherever you stand.
Not to do:
- Not even briefly, and not to shift the vehicle: the motor stays off.
- Switching your key to ignition alone sets your pump going on many diesels. Avoid it.
- Pouring in more diesel doesn't help: AdBlue separates out rather than thinning.
- Any driving at all is best avoided, even a short stretch up Marchbank Drive.
- No emptying it yourself, either, at the verge.
At a forecourt in Balerno, whether it's the Sainsbury's or another one, ask the staff to help you roll your car clear of the petrol pump. At home, the vehicle stays just as it was left.
What does AdBlue do in a diesel tank?
Not your engine but the exhaust is where AdBlue is meant to go. 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 designed to handle it.
Poured in with the diesel, it keeps separate rather than blending — entirely different from fuel. The pickup takes fuel from the lowest part of your tank, and that's precisely where AdBlue ends up: as it is denser than diesel, it sinks. Simplest of all: a vehicle that had AdBlue in Currie overnight and has not been started since. The liquid sits at the foot of your tank, undrawn — though it will be the first thing through if the motor starts, before any diesel at all.
Two kinds of damage come from there. What is left once the water evaporates is urea, which turns into crystals: they settle in tiny channels and block filters. Worse, it attacks some metals in the fuel system, and keeps going until it is cleared out. Pipes carrying AdBlue mean harm overnight for a vehicle sitting in Balerno. Only inside the tank, it stays stable. Water lubricates nothing. The injection pump and every injector need diesel flowing past them, and so the water content harms them in its own right.
Why is AdBlue in a diesel often the bigger issue?
Petrol pumped into a diesel on BP's forecourt makes the fuel thin — that is the whole issue. Mixed into your diesel and left unused, it's no threat at that stage; running your motor is the harm.
The trouble with AdBlue in a diesel is a completely wrong substance. It doesn't burn, so it can't simply be run through. Crystals and corrosion remain after the next fill, and AdBlue splits back out of your diesel, and so thinning it can't work. That is why the flush counts so much, and trying your engine "to see" costs more with AdBlue than nearly any other mistake — in Warriston or the centre of Balerno alike.
The same good news holds as with petrol. Emptying a tank is the simplest job on any fuel system, and with no start-up, the AdBlue remains in it — anywhere across City of Edinburgh your car has stopped.
How does AdBlue end up in a diesel tank in Balerno?
Many cars put the AdBlue filler alongside the diesel cap, now and then behind a single flap, and in dim light the two can look identical. No one means it. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the pump.
The ways it takes place are few and familiar. The top-up gets hurried outside the local primary school, because your dash flashed with a warning while the children were taken in. In the evening, a bottle goes in on a drive near Malleny Avenue. Or the car is topped up in the car park outside The Balerno Inn, in poor light, by somebody who has never opened that flap before.
It happens most in the vehicles drivers know least: a hire car, a new car, a company car, or the second vehicle of a household with one diesel and one petrol. An identical mistake, an identical first step — keep it switched off — anywhere you happen to be around Balerno or the remainder of City of Edinburgh.
Started the engine with AdBlue in your diesel tank around Balerno?
In that case, the AdBlue is no longer in your tank. With any running time, it goes on to the high-pressure pump and each injector, after passing through the fuel filter and pipework.
Watch for rough running, smoke, falling power, warnings on the dash, or a cut-out — returning from Harmeny Wood, say, or part way across Balerno. Stop as soon as it is safe, switch off, and don't restart it to check. Each start pulls more of that through.
Leave the M8, under 3 miles from Balerno, by the next junction and stop somewhere safe, rather than driving on.
How far it went counts. A couple of hundred yards across Balerno to the car park by Willie Shanks Memorial is a very different job from a run towards Edinburgh, under 10 miles away, with the AdBlue reaching further into the system with each mile. Tell us about how far it had come.
We do all of the flushing where your car has stopped, and once the motor has been started there is more of it. Noticed soon, it very rarely leaves permanent damage.
What does an AdBlue drain on a diesel involve in Balerno?
Our technicians come to your car, wherever it has stopped in Balerno: a side street close to Balerno Community Centre, a drive, a lay-by or a forecourt. The work rests on three answers, which our engineers ask for before all else — what was put in, the amount, and whether your engine has turned over.
Next, draining your tank on the spot takes out the contaminated diesel and the AdBlue together. Residue from AdBlue won't flush away unaided, so the whole system gets a full flush, which counts far more here than with petrol. A test of your vehicle follows at the end, after clean diesel goes in and your filter gets flushed or, where necessary, replaced. If your engine has not run, the majority of jobs take about half an hour once our technicians are there. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.
Lastly, the system is primed with fresh diesel. Whether it's a parking space at Curriehill or a drive in Balerno, that is where our engineers start it and you set off. Before we go, our engineers make sure it is running properly with clean diesel in. Since the job is done in full where the car is, a workshop never comes into it. You receive a VAT invoice and an engineer report later, which is what insurers want.

What does AdBlue in a diesel tank cost to sort out in Balerno?
Not one single figure could be fair, because every job differs. Whether the engine has run, and for how long, comes first in what moves the cost. How much AdBlue went in comes next, and then the location of the vehicle, since an open driveway is easier for a technician to get to safely than a tight gap behind Balerno Farmer's Market.
Which fluid got in, how much, plus whether the engine ran: each Balerno call opens with precisely that, before a quote, never after. Their replies narrow the range down to a single figure.
You get that price by phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront. Look at your policy whilst we are on the way: plenty carry misfuelling cover.
