AdBlue in the Diesel Tank in Thorp? Keep It Switched Off

AdBlue in the diesel tank? Then keep the engine off — and your ignition as well. Urea dissolved in water is what AdBlue is. Unlike fuel, it neither burns nor blends, and no harm starts until your motor pulls it through. Caught before your engine has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the car is around Thorp. Ring 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in your diesel tank around Thorp

To do:

  • Keys out — then no one can switch anything on.
  • If you are anywhere close to moving traffic, put your hazards on.
  • Which fluid, and about how much amount? Hang on to the bottle or the receipt, and our technicians will know.
  • Call us from where you are. A postcode starting OL2 5, or the name of the closest street, gets the van to you without a search.

Things not to do:

  • No starting the motor — not for a second, not to shift your car.
  • Your ignition stays off: on many diesels, switching it on is enough to start the fuel pump.
  • Do not top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
  • Any driving at all is to be avoided, even a short distance up Westerdale Drive.
  • No draining it yourself, at all, on the roadside.

The staff working at any Thorp forecourt — the Shell among them — will normally lend a hand rolling it aside if you ask. If you're on your own drive, leave the car precisely where it sits.

AdBlue in a diesel tank, and what it does there

AdBlue is made for your exhaust, not your motor. From a separate reservoir it is fed directly to the exhaust, treating what the engine lets out. A fuel pump isn't made to cope with it, and AdBlue was never intended to travel through one.

Fuel blends; AdBlue, once poured in, won't. The behaviour is nothing like diesel's. Heavier than diesel, it drops and collects below it — the very spot the pickup draws from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Royton last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.

After it's drawn in, the harm takes two forms. It eats at some metals found in fuel systems, working on whatever it touches until it is cleared from your system. And when the water goes, the urea forms crystals that block filters and lodge in tiny passages. Overnight, a car parked in Thorp with AdBlue through its pipework gets worse; where it is just inside your tank, it doesn't. The water in it does harm of its own: the high-pressure fuel pump and your injectors rely on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Thorp

AdBlue in a diesel: why it's regularly worse than petrol

Top up a diesel with petrol in error at the Red Rose Filling Station, and the issue is diluted fuel. Blended through the diesel and left still, it is harmless at that stage; using your motor is the harm.

With AdBlue in a diesel, the liquid itself is simply the wrong one. It cannot just be run through, because it does not burn. Whether the car is in Holden Fold or the heart of Thorp, turning it over "to see" costs more in this case than almost any other slip, and the flush counts more. Why: it will not remain mixed, and so watering it down fails; and deposits and corrosion survive the next tankful.

As with petrol, there's good news. If your engine has not run, the AdBlue is still in the tank, and your tank is the quickest part of a fuel system to clear, wherever around Greater Manchester your car is standing.

Thorp: how AdBlue ends up in a diesel tank

It is not deliberate. Plenty of vehicles keep the AdBlue inlet alongside the diesel inlet, now and then behind one flap, and mixing them up is simple after dark. It usually occurs at home, from a container bought en route home, rather than at the filling station.

A few familiar ways account for most cases. The top-up gets hurried outside Thorp Primary School, because the dash lit up with a warning while the kids were dropped in. Close to Harewood Drive, someone pours a container in at home in the evening. Or a driver unfamiliar with that flap refills the car in dim light, parked in the car park by The Junction Inn.

It takes place most in the motors motorists know least: a hire car, a new vehicle, a company car, or the second motor of a household with one diesel and one petrol. Leave it off: that's the first step to an identical mistake, wherever in Thorp or the remainder of Greater Manchester you happen to be.

AdBlue in the diesel tank in Thorp, and your engine started?

Then the tank is no longer where the AdBlue is. With any running time, it goes on to the injection pump and each injector, having passed via the fuel filter and lines.

Maybe returning from Dogford Park, or part way across Thorp, your engine may go rough, smoke, lose power, flash your dash or stall. No starting it again to check: stop when it is safe, then turn it off. Each start pulls more of that through.

If you were on the A627(M), under a mile from Thorp, come off at the next junction and stop somewhere safe instead of pressing on.

Distance counts: every mile carries the AdBlue further into your system, so heading for Manchester, under 10 miles away, gives a much larger job than hopping across Thorp to the car park by Boyes. Roughly how far had it come? Tell us.

Our engineers do all of the cleaning where your car has come to a stop, and once the engine has been started there is more of it. Caught quickly, it very seldom leaves long-term damage.

Thorp: how AdBlue is drained from a diesel

The car stays put, whether that is a street near Royton Library, a drive, a layby or a filling station around Thorp, and our van comes to it. The work rests on three answers, and our engineers get before all else — what went in, the amount, and whether the motor has run.

On the spot, the tank is then drained, and all of the contaminated diesel and the urea leave as one. The fuel system is rinsed thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. Next, your filter: cleaned, or replaced when it has to be. After that clean diesel, and then a test of your vehicle. About half an hour once we arrive is usual for most jobs when the engine hasn't run. Quiet enough to use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.

Priming the system with fresh diesel comes last. You head off as soon as we have started it, and it makes no difference whether your car is on a drive in Thorp or in a bay outside Mills Hill. The test before our technicians head off is that it runs smoothly on new diesel. The entire job is done where the vehicle is, so it never has to go to a workshop. Afterwards, you are given paperwork for your insurer: a VAT invoice and a report from the engineer.

About Thorp

Thorp is a suburban area in Greater Manchester, situated near the River Irwell and characterised by semi-detached housing. Thorp sits at an elevation of 162 metres, approximately 7.7 miles from Manchester city centre. Thorp is part of a larger urban landscape that includes nearby places like Oozewood, Haggate, and Royley. Thorp has a population of around 5646 residents, living in a mix of old and new buildings.

AdBlue drains across Thorp and Greater Manchester

Our vans that answer AdBlue calls in Thorp also cover the spots about it, Oozewood, Haggate and Royley among them, and most of Greater Manchester beyond, across the OL postcode area. If you're near a border, or somewhere hard to describe, ring and ask instead of assuming.

Thorp is a residential suburb, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it is, so it never needs to be shifted to us.

Thorp: what AdBlue in a diesel tank costs to fix

Not one flat figure could be honest, since each job is different. Whether the motor has run, and for how long, comes first in what changes the cost. How much AdBlue went in comes next, and then the location of the car, since an open driveway is simpler for our van to reach safely than a tight gap behind Royton Town Hall.

With that reason, every call from Thorp begins with the same trio — what got in, what quantity, whether it ran — ahead of a figure. Their replies shrink a range down to a single number.

Quoted on the call before the engineer heads out, it is settled that day — card or phone, nothing in advance. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.

In Thorp and still next to your car?
