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

With AdBlue in your diesel tank, your ignition remains off and so does your engine. Chemically, AdBlue is just urea in water. The trouble starts once it is sucked through the lines — it won't burn, and it won't blend with diesel. In Gwills, AdBlue in a diesel tank caught before your engine runs normally means a drain and a thorough flush, just where your car is. Before anything, ring us on 0333 366 0103.

Gwills, AdBlue in the diesel tank: what to do at once

To do:

  • So nobody can switch your ignition on, pull your keys out.
  • Close to moving traffic? Then put the hazards on.
  • So you can tell us which liquid it was and about how much, keep your receipt or the empty bottle.
  • Call us from where you are. A postcode starting TR8 5, or the name of the closest street, brings our van to you without a search.

Not to do:

  • Not even for a second, and not to roll the car: the motor remains off.
  • Switching the key to ignition alone starts your pump running on many diesels. Skip it.
  • AdBlue doesn't mix in diesel — it separates out — so adding extra diesel won't thin it.
  • Any driving at all is best avoided, including a short way up Bownder Vewin.
  • No draining it yourself, at all, at the verge.

Get the people behind the counter to help you roll the car off the pumps if you are on a forecourt in Gwills, whether it's the Morrisons or somewhere else. At home, the vehicle remains exactly where it was left.

AdBlue in a diesel tank: what it does

Not your motor but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into your exhaust gas to fresh it. No part in an injection pump is made for this liquid — and no part of that was meant to go that way.

Poured in with the diesel, it stays separate rather than blending — entirely unlike fuel. It sinks, since it's heavier than diesel, and pools down where the intake takes its fuel from. Once the pump runs, the AdBlue is first to go through. Until then it sits beneath your diesel, which is how a vehicle filled in Treninnick yesterday and not switched on remains the straightforward case, provided no one touches your key.

From there it causes two kinds of damage. What remains when the water goes is urea, which forms crystals: they lodge in tiny channels and block filters. Worse, it eats at certain metals in the fuel system, and keeps going till it's cleared out. A motor left standing in Gwills with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. Diesel protects the injection pump and every injector as it flows; water offers no lubrication, which is a separate kind of harm.

Draining AdBlue from a diesel tank in Gwills

Why AdBlue in a diesel is often more major than petrol

Petrol pumped into a diesel on Esso's forecourt makes your fuel thin — that is the whole problem. Mixed through the diesel and left unused, it is harmless at that stage; using your motor is the damage.

AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all. Not burning, it cannot simply be run through. Whether your car sits in Trevoll or the heart of Gwills, turning it over "to see" costs more in this case than nearly any other slip, and the flush counts for more. Why: it will not remain mixed, so diluting it fails; and crystals and corrosion outlast the following tankful.

The same good news holds as with petrol. If your engine has not run, the AdBlue is still in the tank, and the tank is the simplest part of a fuel system to clear, wherever in Cornwall the car is sitting.

How AdBlue ends up in a diesel tank in Gwills

In dim light, two caps together — the AdBlue cap and the diesel one, now and then behind one flap — can look the same. No one intends it; many layouts allow it. It mostly occurs outside the house, from a container bought on the journey home, not at the filling station.

A few familiar ways account for the majority of them. Hurrying, outside The Bishops CofE Learning Academy, after a warning lamp flashed on during the school run, someone tops up your car. A driver pours the container in outside their house, just off Hyns an Vownder, as the day ends. Or your car is topped up in the car park outside the pub in the village, in poor light, by a person who has never opened that flap before.

Rented vehicles, new motors, company motors, or the second vehicle in a family with one of each: the least familiar vehicles get it most. Anywhere around Cornwall, Gwills included, the slip does not change, and neither does the first response: keep it off.

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

Then your tank is no longer where the AdBlue is. Given any running, it travels to the injection pump and every injector, after passing through your filter and pipework.

You may notice your motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Trenance Gardens or halfway across Gwills. Stop when it is safe. Switch off. Keep the vehicle off rather than testing it again. Each start pulls more of that through.

On the M5, over 50 miles from Gwills, the next junction is where to exit, and anywhere safe is where to stop — not driving on.

Every mile pushes the AdBlue further into the system. That is why crossing Gwills to park near Lane Theatre and a drive of under 10 miles towards Truro are such separate jobs. Let us know roughly how far it had come.

Once your engine has been run, the flush covers more, and all of it is done where the vehicle has ended up. When it's caught early, long-term damage is very uncommon.

Clearing AdBlue in a diesel around Gwills: what it takes

Wherever it has come to rest around Gwills — a filling station, a layby, a drive, a street beside Atlantic Centre — the van travels to the car. Three answers decide the work, so first we ask what got in, roughly what quantity, and whether the motor has turned over.

Next, emptying that tank right there removes the contaminated diesel along with the AdBlue in one go. The system is purged thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. Next, the fuel filter: cleaned, or replaced when it must be. After that clean diesel, then a check of the car. Roughly half an hour on site is typical for most jobs when your motor has not run. Low-noise enough for use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

Clean diesel goes in to bleed your system, and that is the final step. After that we start the car and you set off, whether from a parking space by Quintrell Downs or a drive in Gwills. The test before we go is that it runs properly on fresh diesel. The entire job is done where your car is, so it never needs to be taken to a workshop. Your insurer will want an engineer's report and your VAT invoice — both yours once this job is done.

About Gwills, for a moment

Gwills is a small coastal locality in Cornwall, situated near the city of Truro and close to the nearby places of Lane, Trencreek, and Trevemper. Gwills has a population of around 606 people and is characterized by predominantly terraced housing. Gwills is located at a low elevation of 7 metres above sea level, reflecting its coastal setting.

AdBlue drains around Gwills and across Cornwall

AdBlue jobs around Gwills go to vans that serve the towns around it — Lane, Trencreek as well as Trevemper — and most of Cornwall beyond, across TR postcodes. Ring and ask instead of guessing if you're close to a border, or somewhere awkward to pin down.

Anywhere your car sits — a driveway at home, a residential street, a parking area, a filling station — our technicians empty it on the spot, with no need to bring it to us; that suits Gwills, a coastal area, well.

AdBlue in a diesel tank in Gwills: the cost of fixing it

No flat figure would be honest, since each job is different. The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where the car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight space behind Waterworld.

Which fluid got in, how much, plus if the engine ran: every Gwills call opens with precisely those, before a figure, not afterwards. Those replies turn a range into a straight price.

Priced on the call before the van sets out, the job is paid for that day — card or phone, no deposit. As the van is on the way, dig out your policy: plenty cover misfuelling.
