Belfast: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that is how you begin if AdBlue has gone into your diesel tank. Water with urea dissolved in it: that is AdBlue. Not like fuel, it neither ignites nor mixes, and no harm happens until your engine pulls it through. A drain and a thorough flush, done where your car is around Belfast, is usually what AdBlue in a diesel tank takes — if it is caught before the engine has run. Before you do anything else, phone 0333 366 0103.
AdBlue in the diesel tank in Belfast: the first few minutes
Do these:
- Pocket the keys, and that stops someone turning the power on.
- Hazards on, if moving traffic is at all close.
- Keep your receipt or the empty bottle, so you can tell us what got in and roughly how much.
- Ring us from where you are. A postcode starting BT1 5, or the name of the nearest street, brings the van to you without a search.
Do not do these:
- Moving the car even a short way is no reason to fire up the motor.
- Switching the key to ignition by itself sets the pump going on many diesels. Skip it.
- AdBlue does not mix in diesel — it separates out — so adding extra fuel will not weaken it.
- Don't drive the vehicle anywhere, not even a short stretch down Heugh Road.
- Emptying the tank on your own by the road is not worth trying.
Moving your car away from the pumps is a job for attendants to help with, whichever Belfast forecourt you're on, the the nearest petrol station included. Parked on your own drive? Then it stays just as it is.
What AdBlue does in a diesel tank
Made for your exhaust, AdBlue has no business in the motor. Its own reservoir keeps it, and from there it's fed into your exhaust, where it treats the gas. Neither side fits the other: urea doesn't belong in a pump, and an injection pump can't take urea.
Inside a diesel tank it acts very differently from fuel. It doesn't mix in. Heavier than diesel, it drops and collects underneath it — the same spot the intake sucks from. When the pump runs, the AdBlue is top of the list to be pulled through. Until then it waits beneath the diesel, which is how a vehicle topped up in Ballylesson last night and never started remains the simple case, provided nobody touches your key.
From there it causes two kinds of harm. What is left once the water goes is urea, which forms crystals: they lodge in tiny channels and clog filters. Worse, it eats at certain metals in the fuel system, and keeps going until it's cleared out. Pipes holding AdBlue mean harm overnight for a vehicle sitting around Belfast. Just in your tank, it stays stable. Water lubricates nothing. The high-pressure pump and every injector depend on diesel flowing through them, and so the water content harms them in its own right.
Why AdBlue in a diesel is regularly more major than petrol
Put petrol in a diesel at the another forecourt nearby and you have a fault of thin fuel. It mixes with your diesel, and while it is in the tank it causes no damage; the harm comes from running your engine on it.
The issue with AdBlue in a diesel is a completely unsuitable liquid. Since it does not burn, running it through isn't an option. Nor can it be thinned, because it splits back out — and the following tankful won't clear away deposits or corrosion. So the flush matters for more here, and turning your key "to see", in the heart of Belfast or out in Dunmurry, does more harm than almost any other mistake.
With AdBlue, the good news is no distinct from petrol. Wherever around County Antrim your car has stopped, an unstarted motor means the AdBlue still inside the reservoir: the simplest bit of any fuel system to clear.
AdBlue in a diesel tank around Belfast: how it ends up there
No one means to do it. The AdBlue filler on plenty of vehicles sits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. A container picked up when heading home and tipped in at home, rather than at the forecourt, is the typical route.
The ways it occurs are few and familiar. A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school. Close to South Crescent, a driver tips a bottle in at home in the evening. Or someone unfamiliar with that flap tops up your vehicle in dim light, parked in the car park outside the pub in the village.
The least familiar cars get it the most — rentals, brand-new cars, fleet ones, and the spare car of a home with both fuel types. Leave it switched off: that is the first step to an identical mistake, wherever in Belfast or the rest of County Antrim you happen to be.
Belfast: started the engine with AdBlue in the diesel tank?
Then the tank is no longer where the AdBlue is. With any running time, it goes on to the high-pressure pump and each injector, having passed via the filter and lines.
You may see your motor running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from the green space at the edge of the village or halfway across Belfast. When you safely can, pull over and switch it off — without turning it on again to test. Each start pulls more of that through.
Leave the M77, over 50 miles from Belfast, at the first junction and park safely, not driving on.
Mileage matters: each mile carries the AdBlue deeper in, so driving towards Lisburn, under 10 miles away, gives a far larger job than hopping across Belfast to the car park by the centre. Let us know roughly how far it had come.
Wherever your car came to a halt is where all of it gets done, even with more to clean out once your engine has been run. If it is noticed quickly, lasting damage is very unusual.
Clearing AdBlue in a diesel in Belfast: what it takes
Our engineers come to your car, wherever it has stopped around Belfast: a side street close to a street just off the centre, a drive, a lay-by or a forecourt. Before anything else our engineers ask what went in, roughly how much, and whether your engine has been run, since those answers settle this work.
Next, emptying that tank right there takes out the contaminated diesel and the AdBlue together. Residue from AdBlue won't flush out unaided, so the whole system gets a careful flush, which matters far more here than with petrol. Clean diesel goes in after the fuel filter is cleaned — or replaced, when it needs to be — and then your car is tested. Engine not run? Then count on roughly half an hour on site for most jobs. Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough not to disturb the street at night.
Finally, your system is primed with clean diesel. Firing it up comes next, and then you head off from where the car is parked, by the nearest station or on a driveway around Belfast. It is tested on fresh diesel to make sure it runs correctly before our technicians head off. We do it all wherever the vehicle has ended up, and it never has to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come afterwards.
About Belfast, for a moment
Belfast is a major city situated on the coast of Northern Ireland, where the River Lagan meets the sea. It serves as the country's capital and main port, benefiting from its strategic location. The city is nestled in County Antrim, overlooking the water. Belfast is known for its significant size and importance in the region.
Belfast and County Antrim: AdBlue drains across the area
Throughout the BT postcode area, the vans taking AdBlue call-outs around Belfast reach much of County Antrim as well, Finaghy, Edenderry and Holywood included. Guessing won't help by a county line or somewhere tricky to pin down; phone and ask.
No moving is needed. In Belfast, a capital city, a van that comes to you fits: your car is emptied on the spot, be it on a driveway, a residential street, a car park or a filling station.
AdBlue in a diesel tank in Belfast: the cost of fixing it
Because each callouts vary, a single figure would not be honest. What changes the price is, firstly, whether your engine has run and for how long; then how much AdBlue was put in; and finally where the vehicle is and whether our van can get to it safely, which is simpler on an open drive than in a tight gap behind the far end of the built-up part.
That's why each call from Belfast starts with the same three questions, asked before giving a figure, not after: what got in, how much, and whether it has run. Their answers shrink the range down to a single figure.
Before anyone heads out, you are told the price by phone. Then payment is on the day, by card or by phone, with nothing in advance. Look at your insurance whilst we're on the way: plenty include misfuelling cover.
Belfast: still alongside your car?
Then the most handy thing you can do is nothing to your car. Keys out, engine off, ignition off. Phone 0333 366 0103: AdBlue, roughly how much, and if it ran are all our engineers ask. Petrol in Diesel takes over the remainder throughout County Antrim, Belfast too.
