Battlefield: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in the diesel tank, the ignition stays off and so does your motor. Urea dissolved in water is all AdBlue is. It does not burn, it doesn't mix with diesel, and the damage it does begins when your fuel system pulls it in. If the motor has not run yet, AdBlue in a diesel tank is usually emptied and carefully flushed where your car sits in Battlefield. Nothing comes before calling 0333 366 0103.

Your next steps straight away, Battlefield: AdBlue in your diesel tank

Do these:

  • Pull your keys out, and so nobody switches your ignition on.
  • If you're anywhere near moving traffic, put the hazards on.
  • Which product, and about what volume? Hang on to the bottle or the till receipt, and our technicians can see.
  • Give us a postcode starting SY1 4, or whichever street is nearest, and the van reaches you directly — so ring wherever you are.

Things not to do:

  • Shifting the vehicle even a few yards is no reason to start your engine.
  • Many diesels power their pump the instant the ignition goes on, so keep the car off.
  • Don't top up with diesel to dilute it. AdBlue doesn't dilute in diesel; it separates out.
  • Never drive the car anywhere, not even a short stretch along Lion Coppice View.
  • No draining it yourself, at all, at the roadside.

The attendants on duty at any Battlefield forecourt — the BP included — will normally lend a hand pushing it clear if you ask. On your own drive, do not touch it at all.

AdBlue in a diesel tank, and what it does there

Made for your exhaust, AdBlue has no business in your engine. Its own reservoir keeps it, and from there it's sprayed into the exhaust, and there it treats the gas. Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea.

Inside a diesel tank it behaves very differently from fuel. It does not mix in. The intake takes fuel from the deepest part of the tank, and that is exactly where AdBlue ends up: as it is heavier than diesel, it sinks. Once the system runs, the AdBlue is top of the list to go through. Until then it sits underneath your diesel, which is how a vehicle filled in Broadoak last night and not started stays the simple one, as long as no one turns the key.

From there it does two kinds of harm. It eats at some metals found in fuel systems, working on whatever it reaches until it is cleared from your system. And once the water evaporates, the urea forms crystals that clog filters and settle in narrow passages. If the AdBlue has reached the lines, leaving it overnight in Battlefield makes it worse. In that tank only, waiting does nothing. Diesel lubricates the high-pressure pump and every injector as it flows; water offers none of that, which is a separate form of harm.

Draining AdBlue from a diesel tank in Battlefield

Why is AdBlue in a diesel commonly the bigger issue?

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

The issue with AdBlue in a diesel is a totally wrong substance. Since it doesn't burn, running it through is not an option. Whether the vehicle sits in Heathgates or the centre of Battlefield, turning it over "to see" costs more with AdBlue than nearly any other slip, and the flush counts more. Why: it won't stay blended, so diluting it fails; and deposits and corrosion outlast the following fill.

As with petrol, there's good news. Clearing a tank is the simplest job on a fuel system, and with no start-up, the AdBlue stays in there — anywhere across Shropshire the vehicle sits.

Battlefield: how AdBlue ends up in a diesel tank

It is not deliberate. Plenty of cars have the AdBlue cap beside the diesel one, occasionally under one flap, and muddling them up is simple after dark. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

A couple of familiar ways account for most cases. Midway through the drop-off, the dashboard warns, and outside Greenacres Primary School the refill is rushed. A bottle is poured in at the end of the day on a drive just off Battlefield Road. Or your car is topped up in the car park at The Red Lion, in poor light, by a person who has never opened that flap before.

The least familiar vehicles get it the most — rentals, new cars, fleet ones, and the other car of a family with one of each fuels. Keep it switched off: that's the first step to the same slip, anywhere in Battlefield or the remainder of Shropshire you happen to be.

Already started your engine with AdBlue in the diesel tank around Battlefield?

Then the AdBlue has left your tank. It has been drawn through your filter and your lines, and if the motor ran for any time, it has got to your high-pressure pump and the injectors.

You may notice your motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Lion Coppice or halfway across Battlefield. Stop as soon as it is safe, switch off, and do not restart the car to check. Each start pulls more of it through.

On the M54, under 10 miles from Battlefield, the next junction is where to exit, and anywhere sensible is where to stop — not driving on.

Hopping across Battlefield to the car park by Climbing Hut is one thing; heading for Wrexham, under 25 miles away, is something else, since every mile pushes the AdBlue further in. So distance matters. Approximately how far had it come? Tell us.

Our technicians do all of the rinsing where your car has come to a stop, and once the motor has run there is more of it. Spotted quickly, it very seldom leaves long-term damage.

Draining AdBlue in a diesel around Battlefield: what it takes

Anywhere it has come to rest in Battlefield — a filling station, a layby, a driveway, a road beside St Mary Magdalene, Battlefield — the van comes to the car. The job depends on three answers, which our engineers ask for before all else — what was put in, the quantity, and if your engine has run.

Right there, the tank is then drained, and both the contaminated diesel and the urea come out at once. Residue from AdBlue won't wash out unaided, and so the whole system gets a full flush, which matters far more here than for petrol. A test of your car follows at the end, after fresh diesel goes in and the filter is cleaned or, if necessary, swapped. Roughly half an hour on site is usual for most jobs when your engine has not run. Low-noise enough for use outside a house at night, and safe on a busy forecourt, our pumps are explosion-proof.

New diesel goes in to prime the fuel system, and that's the final step. You head off as soon as our technicians have fired it up, and it makes no difference whether the vehicle is on a driveway around Battlefield or in a bay by Shrewsbury. Our technicians confirm it runs correctly on new diesel before leaving. No workshop is required at any stage, with the entire job done then and there. The insurer will want an engineer's report and the VAT invoice — both yours once the job is done.

About Battlefield

Battlefield is a suburban area in Shropshire, situated inland at an elevation of 73 metres, with detached housing being the predominant type of accommodation. Battlefield lies approximately 23.9 miles from Wrexham and is close to nearby places such as Upper Battlefield, Harlescott, and Sundorne. Battlefield has a population of around 1329 residents and is located about 139.3 miles from London.

AdBlue drains in Battlefield and across Shropshire

Upper Battlefield, Harlescott and Sundorne are among the towns around Battlefield that the same teams reach, along with much of Shropshire further out, throughout the SY postcode area. If you're near a border, or somewhere hard to describe, ring and ask instead of assuming.

A mobile service fits Battlefield, a residential suburb: you have no need to take your car to us, since we empty it there, in a drive, a residential street, a car park or a filling station.

What does AdBlue in a diesel tank cost to sort out around Battlefield?

No flat price could be honest, because every job is different. Three things change the cost: whether the motor has run and for how long, how much AdBlue was put in, and where the vehicle is. That last one turns on whether a van can reach it safely, and an open drive is easier than a tight gap behind Battle of Shrewsbury.

That is why every call from Battlefield starts with the same three questions, asked before giving a figure, not after: what went in, how much, and whether it has run. Once those are known, a range turns into a single firm number.

You get that price on the phone, before anybody heads out, and you pay on the day, by card or by phone, with nothing upfront. Misfuelling cover comes with many insurance policies, so it is worth looking at yours before the van arrives.

In Battlefield and still next to your car?

Then the most handy thing you can do is nothing to your car. Ignition off, motor off, keys out. Tell us it was AdBlue, about what quantity, and if the engine ran, on 0333 366 0103. From there Petrol in Diesel takes over, in Battlefield or wherever within Shropshire.
