AdBlue in a Diesel Tank in Castlehead? Don't Start It

Engine off, ignition off: that is how you begin if AdBlue has gone into your diesel tank. AdBlue is urea dissolved in water. Not like fuel, it neither ignites nor mixes, and nothing happens until your engine pulls it round. A drain and a thorough flush, done where your car is around Castlehead, is generally what AdBlue in a diesel tank takes — if it's caught before the engine has run. Before you do anything else, phone 0333 366 0103.

Castlehead, AdBlue in your diesel tank: what to do straight away

Do these:

  • Remove the keys, which prevents anyone turning the electrics on.
  • If you are anywhere close to moving traffic, put the hazard lights on.
  • Hold on to the till receipt or the empty bottle, so you can tell us what went in and about how much.
  • Tell us a postcode starting PA2 6, or whatever street is nearest, and the van reaches you straight — so ring wherever you are.

Not to do:

  • Not even briefly, and not to shift the car: the motor stays off.
  • The ignition stays off: on lots of diesels, turning it on is enough to run the pump.
  • Don't top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
  • Keep the car where it is rather than driving it anywhere, even a short way down Low Road.
  • By the road, do not attempt draining it on your own.

Rolling the car away from the pumps is a job for staff to help with, whichever Castlehead forecourt you are on, the Shell included. If you're on your own drive, leave it precisely where it sits.

AdBlue in a diesel tank, and what it does there

AdBlue is made for your exhaust, not the motor. Its own tank keeps it, and from there it's sprayed into the exhaust, and there it cleans the fumes. Not one side fits the other: urea does not belong in a pump, and an injection pump can't deal with urea.

Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. Denser than diesel, it drops and collects underneath it — the same spot the pickup draws from. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Lounsdale last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in.

It causes two kinds of harm from there. It eats at certain metals used in fuel components, attacking whatever it touches till it's removed from the system. And once the water evaporates, the urea turns into crystals that clog filters and settle in narrow passages. Lines holding AdBlue spell harm overnight for a car sitting in Castlehead. Only in the tank, it stays stable. Then there is the water: it brings no protection to the parts that rely on it most — the high-pressure pump and each injector.

Draining AdBlue from a diesel tank in Castlehead

Petrol or AdBlue in a diesel: why AdBlue is regularly worse

Put petrol in a diesel at the Morrisons and you have a fault of thin fuel. It mixes with the diesel, and while it is inside your tank it does no harm; the harm comes from running your engine on it.

AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all. Because it does not burn, running it through is not an option. Whether the car sits in Stanely or the heart of Castlehead, firing it up "to see" costs more in this case than almost any other slip, and the flush matters more. Why: it won't stay blended, and so diluting it is impossible; and crystals and corrosion survive the following tankful.

As with petrol, there's good news. Never started? Then the AdBlue waits only inside that tank, the easiest bit of the entire system to clear, anywhere the vehicle has stopped around Renfrewshire.

Castlehead: how AdBlue ends up in a diesel tank

Many vehicles put the AdBlue filler beside the diesel cap, now and then behind one flap, and after dark the two may look identical. Nobody means it. Mostly it takes place with a bottle bought on the way home and poured in on the drive, not at the pump.

A couple of familiar ways account for most cases. Midway through the drop-off, the dashboard flags it up, and outside the local primary school the refill is rushed. Near Main Road, a driver tips a container in at home after work. One more pattern: dim light, a pub car park by Tartan Rose, and someone opening that flap for the first time.

The least known vehicles get it most — hire cars, new ones, company ones, and the spare car of a family with one of each fuels. Leave it switched off: that's the first step to an identical slip, wherever around Castlehead or the remainder of Renfrewshire you are.

Started the engine with AdBlue in the diesel tank around Castlehead?

Then that tank is no longer where the AdBlue is. Via your filter, along the pipework, and — with any running — into the injection pump and every injector: that is where it travels.

You may notice your engine running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Ferguslie Cricket Club or halfway across Castlehead. Pull over when it is safe. Switch off. Leave the vehicle off rather than testing it again. More of that is pulled through with each start.

Exit the M8, under 3 miles from Castlehead, at the next junction and stop safely, rather than carrying on.

Each mile pushes the AdBlue further in. That is why crossing Castlehead to park near Castlehead Parish Church and a drive of under 10 miles for Glasgow are such separate jobs. About how far it had come is worth telling us.

Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out after the motor has been started. When it's caught soon, long-term damage is very uncommon.

What clearing AdBlue from a diesel involves around Castlehead

Our engineers come to your car, wherever it has stopped in Castlehead: a side street close to Maxwellton Cross Memorial, a drive, a lay-by or a forecourt. Before anything else our technicians ask what went in, about how much, and if the motor has been run, because those replies determine this work.

Right there, the tank is then emptied, and all of the contaminated diesel and the urea come out at once. The fuel system is rinsed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Most of these jobs are a half-hour visit once our technicians turn up, if the motor has not run. Quiet enough to use outside a house at night, and safe on a busy forecourt, our pumps are explosion-proof.

The last step is to bleed the fuel system on new diesel. You head off as soon as our engineers have fired it up, and it makes no difference whether the vehicle is on a drive around Castlehead or in a bay by Paisley Canal. It is checked on clean diesel to be sure it runs properly before we head off. We do it all wherever the vehicle has stopped, and it never has to be taken to a garage. You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Castlehead

There is no honest single price, since the jobs are not the same. What shifts the cost is, first of all, whether the engine has run and for how long; then how much AdBlue went in; and finally where the car is and whether our van can reach it safely, which is simpler on an open drive than in a tight space behind Wellmeadow Bowling Club.

Which fluid got in, how much, and whether the engine ran: every Castlehead enquiry opens by asking exactly that, before any figure, not after. With them, the range narrows to one firm figure.
