Killearn: AdBlue in the Diesel Tank? Leave It Off

AdBlue in your diesel tank? Then leave your motor off — and your ignition as well. Water with urea dissolved in it: that is AdBlue. Being water-based, it will not ignite and won't blend with diesel; damage just starts when your pump begins pulling it. A drain and a thorough flush, done where the car is in Killearn, is normally what AdBlue in a diesel tank needs — if it's caught before your engine has been run. Before you do anything else, ring 0333 366 0103.

What to do straight away, Killearn: AdBlue in your diesel tank

Do these:

  • Take the keys out, so nobody switches the ignition on.
  • If you are at all near moving traffic, put the hazard lights on.
  • Hold on to the till receipt or the empty bottle, and so you can tell us what went in and roughly how much.
  • Call us from where you are. A postcode starting G63 9, or the name of the nearest street, brings the van to you without a search.

Not to do:

  • Not even briefly, and not to shift your vehicle: your engine stays off.
  • Your ignition remains off: on lots of diesels, switching it on is enough to run the pump.
  • Adding extra diesel does not work: AdBlue separates out rather than blending.
  • Never drive it anywhere, not even a short way down Graham Road.
  • No emptying it yourself, at all, at the verge.

The attendants on duty at any Killearn filling station — the the nearest petrol station among them — will normally help rolling it clear if you ask. If you are on your own drive, leave the vehicle precisely where it is.

AdBlue in a diesel tank, and what it does there

Not your motor but your exhaust is where AdBlue belongs. Kept in a separate tank, it is injected into the exhaust to treat the fumes. Nothing inside a fuel pump is designed for this fluid — and no part of that was intended to travel that way.

It doesn't blend. After it is poured into the tank, AdBlue behaves not at all like fuel. It is heavier than diesel, and so it sinks and collects at the bottom of your tank, which is where the pickup sucks fuel from. Once the system runs, the AdBlue is first to go through. Before then it sits underneath the diesel, which is why a car filled in Boquhan last night and not switched on stays the simple case, provided nobody turns the key.

From there it causes two kinds of harm. What remains once the water evaporates is urea, which turns into crystals: they lodge in tiny passages and clog filters. Worse, it eats at certain metals in the fuel system, and keeps going till it is cleared out. Pipes carrying AdBlue spell damage overnight for a vehicle parked in Killearn. Only inside your tank, it stays stable. Water protects nothing. The high-pressure pump and every injector depend on diesel running past them, so the water part damages them in its own right.

AdBlue in a diesel: why it is frequently worse than petrol

A fault of thin fuel is what you end up with after fuelling a diesel with petrol at the another forecourt nearby. Mixed into the diesel and sitting still, it is no threat for now; running the motor does the damage.

AdBlue in a diesel is a fault of the wrong substance altogether. It can't just be run through, because it doesn't burn. Nor can it be thinned, because it splits back out — and the following tankful won't clear away deposits or corrosion. So the flush counts more with AdBlue, and trying the engine "to see", in the heart of Killearn or out in Gartness, does more harm than almost any other mistake.

The same good news applies as with petrol. Anywhere around Stirling your vehicle has stopped, an unstarted engine means the AdBlue still in the tank: the simplest part of a fuel system to empty.

AdBlue in a diesel tank in Killearn: how it ends up there

It is not deliberate. Many cars keep the AdBlue inlet beside the diesel one, occasionally under a single flap, and muddling them up is simple after dark. Usually it is never the forecourt: a driver buys a bottle heading home and pours it in outside the house.

A couple of familiar ways cover most cases. Midway through the drop-off, the dashboard flags it up, and outside the local primary school the top-up is rushed. Near Main Street, someone tips a bottle in at home after work. Else, in dim light by the pub in the village, the car is refilled by a driver using that flap for the first time.

It crops up the most in a rental, a new car, a fleet vehicle, or the other vehicle of a home with both fuel types — the vehicles people know the least. Leave it off: that is the first response to the same slip, anywhere in Killearn or the rest of Stirling you are.

AdBlue in the diesel tank around Killearn, and the motor started?

The AdBlue has left your tank, then. It's been pulled through the fuel filter and your lines, and if your engine ran for any time, it has reached the high-pressure fuel pump and your injectors.

Lumpy running, smoke from the exhaust, lost power, dashboard lights or cutting out: any might appear, maybe midway across Killearn or returning from Queen Elizabeth Field. Stop when safe. Turn off. Leave the vehicle off rather than restarting it to check. Each start pulls more of that through.

Leave the Toll Plaza Interchange, under 10 miles from Killearn, at the first junction and park safely, not carrying on.

How far it went counts. A couple of hundred yards across Killearn to the car park by RAZZAMATAZ THEATRE SCHOOLS is a very different job from a run towards Glasgow, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile. Tell us 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 the motor has been run. Very seldom does it leave long-term damage when it is spotted soon.

What emptying AdBlue from a diesel involves in Killearn

The car stays put, whether that's a street near Old Kirk, a driveway, a lay-by or a forecourt in Killearn, and the van comes to it. Three replies decide the work, so before anything else our technicians ask which fluid was put in, about what quantity, and whether your motor has run.

Then that tank is cleared where your car waits, so the tainted fuel and the AdBlue come out together. With AdBlue, far more than with petrol, flushing matters: the whole system is flushed all the way through because what remains will not flush away unaided. A test of your car follows last, after fresh diesel is added and your filter gets cleaned or, if necessary, replaced. If your motor has not run, the majority of jobs take about half an hour once our engineers arrive. Explosion-proof pumps mean a busy forecourt safe to work on, and they run quiet enough not to disturb the street at night.

The last step is to bleed the fuel system on clean diesel. Whether it's a parking space outside Milngavie or a drive around Killearn, that is where our engineers start the car and you head off. The test before we leave is that it runs properly on fresh diesel. Our engineers do it all wherever the vehicle has stopped, and it never has to go to a garage. Insurers ask for a VAT invoice and an engineer report, and both come at the end.

AdBlue drains across Stirling, Killearn included

Branziert, Spittal and Dumgoyne are among the places around Killearn that the same vans reach, along with much of Stirling further out, throughout the G postcode area. Assuming doesn't help by a border or anywhere tricky to describe; ring and check.

Wherever your vehicle sits — your drive at home, a residential street, a parking area, a filling station — our engineers empty it there, with no need to take it to us; that suits Killearn, a village, well.

What AdBlue in a diesel tank costs to put right in Killearn

Every job differs, so not one single quote would be honest. Whether the motor has been running, and for how long, comes first in what changes the price. How much AdBlue went in comes next, and then the position of the vehicle, since an open drive is simpler for a technician to get to safely than a tight gap behind War Memorial.

Ahead of a quote, not afterwards, every call from Killearn opens with the same three questions: the liquid, the quantity, and if it ran. Their replies narrow a range right down to one figure.

Before anyone sets off, you hear our quote by phone. Then payment is on the day, card or by phone, with nothing in advance. Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van arrives.
