Maryhill: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into the diesel tank, leave your engine off and keep the ignition off. Urea dissolved in water is all AdBlue is. The trouble begins once it is sucked through your lines — it won't burn, and it will not combine with diesel. If the motor hasn't run yet, AdBlue in a diesel tank is usually drained and carefully cleaned where your car sits around Maryhill. Nothing comes before calling 0333 366 0103.

Those opening minutes: AdBlue in your diesel tank in Maryhill

Do:

  • Pocket the keys, and that prevents someone switching the power on.
  • Hazards on, if moving traffic is anywhere near.
  • Which fluid, and roughly what quantity? Save the bottle or the receipt, and we will know.
  • Ring us from where you are. A postcode starting G20 0, or the name of the nearest street, gets the van to you without a search.

Never do these:

  • Don't start your motor, even for a moment to move the vehicle.
  • Many diesels power their pump the moment the ignition goes on, so leave the vehicle off.
  • No more fuel on top. The AdBlue won't blend, so it is wasted.
  • Leave the car where it is rather than driving it anywhere, even a short stretch up Maryhill Road.
  • No emptying it yourself, either, on the roadside.

Rolling your vehicle away from the pumps is a job for attendants to help with, whichever Maryhill forecourt you are on, the BP included. If you are on your own drive, leave the vehicle precisely where it sits.

What AdBlue does in a diesel tank

The motor isn't what AdBlue is made for; your exhaust is. Kept in a dedicated tank, it's squirted into the exhaust stream to clean the gases. A fuel pump isn't designed to take it, and AdBlue was never intended to go through one.

Fuel mixes; AdBlue, after poured in, will not. The behaviour is not at all like diesel's. It's heavier than diesel, so it sinks and collects at the bottom of the tank, which is where the pickup pulls fuel from. Easiest of all: one that had AdBlue in Kelvindale last night and has not turned since. The liquid sits at the base of your tank, untouched — though it would be the first thing through if the engine runs, ahead of any diesel at all.

It causes two kinds of damage from there. Crystals and corrosion. As the water dries, it strands urea that crystallises in filters and narrow passages; meanwhile, since it attacks some metals, every part it reaches suffers for as long as it stays inside. If the AdBlue has reached the lines, leaving it till morning around Maryhill makes it worse. Inside that tank alone, waiting costs nothing. Diesel protects the injection pump and each injector as it flows; water offers no lubrication, which is a second kind of damage.

Draining AdBlue from a diesel tank in Maryhill

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

Fill a diesel with petrol in error over at the Shell, and this problem is thinned fuel. It mixes with your diesel, and while it is in that tank it does no harm; the harm comes from running the motor on it.

The trouble with AdBlue in a diesel is a completely unsuitable substance. It cannot just be run through, since it doesn't burn. Crystals and corrosion remain through the next tankful, and AdBlue separates again out of your diesel, so thinning it won't work. Hence the flush counts so much, and trying the engine "to see" does more harm with AdBlue than nearly any other slip — in Gilshochill or the centre of Maryhill alike.

The good news is the same as with petrol. Not run? Then the AdBlue sits only inside the tank, the easiest bit of the whole system to empty, wherever the car has stopped across Glasgow City.

How does AdBlue end up in a diesel tank around Maryhill?

Many motors place the AdBlue cap alongside the diesel cap, now and then under one flap, and after dark the two can look the same. No one intends it. A container picked up while driving home and tipped in at home, rather than at the filling station, is the usual route.

It tends to occur in a couple of familiar ways. 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 Cowal Street, someone tips a bottle in at home after work. Or someone new to that flap tops up the vehicle in dim light, parked in the car park outside The Ram's Head.

Rented motors, new motors, fleet cars, or the second vehicle in a home with both fuels: the least known vehicles get it most. Wherever in Glasgow City, Maryhill included, the slip doesn't change, and nor does the first step: leave it switched off.

Already started the engine with AdBlue in the diesel tank in Maryhill?

Then the tank is no longer where the AdBlue is. The filter and pipework have had it pulled through, and some running carries it on to the high-pressure pump and each injector.

Lumpy running, smoke, lost power, dashboard warnings or cutting out: each might appear, maybe midway across Maryhill or returning from Maryhill Park. No restarting to test: stop once safe, then switch it off. More of that is pulled through with each start.

Exit the M8, under 3 miles from Maryhill, by the next junction and park safely, rather than driving on.

How far it went counts. A few hundred yards across Maryhill to the car park by Martyr's Memorial Pillar is a very different job from a run towards Glasgow, under 5 miles away, with the AdBlue reaching further into your system with every mile. Let us know roughly how far it had come.

Wherever the car came to a stop is where all of it gets done, even with more to flush after the engine has been started. Long-term damage is very uncommon if it's caught early.

What emptying AdBlue from a diesel involves in Maryhill

The vehicle remains where it is, whether that's a road near Maryhill Parish Church, a drive, a layby or a forecourt around Maryhill, and our van travels to it. The job rests on three replies, and we get before all else — what was put in, the quantity, and if your motor has turned over.

Right there, your tank is then emptied, and all of the polluted diesel and the urea come out at once. Residue from AdBlue will not wash away by itself, so the fuel system gets a full flush, which matters far more here than with petrol. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Roughly half an hour on site is usual for most jobs when the engine has not run. Low-noise enough to use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.

Bleeding your system with new diesel comes last. Starting the car comes next, and then you drive off from where the car is parked, by the nearest station or on a driveway around Maryhill. The check before our technicians head off is that it runs properly on clean diesel. Since the job is done in full where the car is, a workshop never comes into it. You get a VAT invoice and an engineer report afterwards, which is what insurers want.

About Maryhill and where it is

Maryhill is a suburban area in Glasgow City, situated on the River Kelvin and close to the River Clyde, with a mix of tenements and modern flats at an elevation of around 42 metres. Maryhill lies approximately 3 miles northwest of Glasgow city centre, near neighbouring areas such as Acre, Dawsholm, and Wyndford. Maryhill has a population of around 7835 people, predominantly residing in flat-type housing. Maryhill is also relatively distant from London, at around 347 miles away.

Maryhill and Glasgow City: AdBlue drains across the area

AdBlue call-outs around Maryhill go to teams that serve the towns around it — Acre, Dawsholm as well as Wyndford — and most of Glasgow City beyond, throughout G postcodes. Guessing won't help close to a border or somewhere tricky to describe; ring and ask.

No towing is needed. In Maryhill, a residential suburb, a mobile service fits: the vehicle is emptied where it stands, be it in a drive, a residential street, a parking area or a forecourt.

Maryhill: what AdBlue in a diesel tank costs to fix

There's no honest single quote, 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 got in; and then where your car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight space behind Gairbraid Parish Church.

With that in mind, each call from Maryhill begins by asking the identical trio — which fluid got in, how much, whether the engine ran — ahead of a figure. With them, a range shrinks to one firm figure.

Quoted on the call before the engineer heads out, it is paid for on the day — card or phone, no deposit. Many insurance policies include misfuelling cover, and so it is worth checking yours while we are on the way.

Still alongside the vehicle around Maryhill?

Then, touch nothing — that's the most helpful step available. Engine off, keys out, ignition off. Petrol in Diesel takes over the rest, across Maryhill or anywhere in Glasgow City, once you call 0333 366 0103 saying it's AdBlue, about what quantity, and whether it ran.
