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

Motor off, ignition off: that's where you start if AdBlue has got into the diesel tank. AdBlue is urea mixed in water. Being water-based, it will not burn and won't blend with diesel; damage just comes when the pump starts drawing it. A drain and a thorough flush, done where the vehicle is around Horncastle, is generally what AdBlue in a diesel tank needs — if it's caught before your engine has run. No step comes before ringing 0333 366 0103.

AdBlue in your diesel tank in Horncastle: the first few minutes

To do:

  • Pull your keys out, so nobody switches your ignition on.
  • Near moving traffic? Then put your hazards on.
  • Hold on to your receipt or the empty bottle, so you can tell us what got in and roughly how much.
  • Ring just where you are. Say a LN9 5 postcode or the closest street sign, and nobody has to search for you.

Never do these:

  • Do not start the motor, even for a moment to move your car.
  • Many diesels power their fuel pump the instant the ignition comes on, and so leave it off.
  • AdBlue doesn't mix in diesel — it separates out — so adding more fuel will not weaken it.
  • Keep it where it is rather than driving it anywhere, even a short way up St. Lawrence Street.
  • No emptying it yourself, at all, at the verge.

Get the people behind the counter to help you roll your car away from the pumps if you are on a forecourt in Horncastle, whether it is the Richard Dear/Total or elsewhere. On your own drive, do not move it at all.

What AdBlue does in a diesel tank

AdBlue is made for the exhaust, not your engine. From a dedicated reservoir it goes straight to your exhaust, cleaning what the motor lets out. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Inside a diesel tank it acts very differently from fuel. It does not mix in. It sinks, because it's heavier than diesel, and pools low where the pickup draws its fuel 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 West Ashby last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.

From there it does two kinds of harm. It eats at certain metals used in fuel components, working on whatever it touches until it's removed from the system. And once the water evaporates, the urea turns into crystals that block filters and settle in narrow passages. A vehicle left sitting around Horncastle with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. The water in it causes harm of its own: the high-pressure fuel pump and the injectors depend on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Horncastle

Why AdBlue in a diesel is often more serious than petrol

Top up a diesel with petrol by mistake at the Shell, and the issue is thinned fuel. Damage just comes from driving on it. Mixed into your diesel and left inside that tank, it does none.

The issue with AdBlue in a diesel is a totally wrong substance. It does not burn, and so it can't simply be run through. Deposits and corrosion remain through the following tankful, and AdBlue splits back from your diesel, so thinning it can't work. Hence the flush counts more, and turning your key "to see" costs more here than nearly any other slip — in High Toynton or the centre of Horncastle alike.

With AdBlue, the good news is no different from petrol. Never run? Then the AdBlue sits only inside that tank, the simplest bit of the entire system to empty, anywhere the vehicle has stopped across Lincolnshire.

Horncastle: how AdBlue ends up in a diesel tank

It's not on purpose. Many vehicles keep the AdBlue cap alongside the diesel inlet, now and then behind a single flap, and muddling them up is simple in poor light. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

The ways it happens are few and familiar. Midway through the drop-off, the dashboard flags it up, and outside Horncastle Primary School the refill is rushed. A driver tips the bottle in at home, right off Market Place, as the day ends. Or a driver new to that flap refills the car after dark, stopped in the car park by The Punch House.

It comes up most in a hire car, a new car, a company motor, or the spare motor of a home with both fuel types — the cars people know the least. Same slip, an identical first response — keep it switched off — wherever you happen to be in Horncastle or the rest of Lincolnshire.

AdBlue in your diesel tank around Horncastle, and the engine started?

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

Perhaps coming back from Hamerton Gardens, or midway across Horncastle, the motor may run rough, smoke, drop power, light up the dash or cut out. Stop when it is safe. Switch off. Keep the car off rather than testing it again. With each start, more of that is pulled through.

If you were on the M180, under 50 miles from Horncastle, come off at the next junction and stop somewhere safe instead of pressing on.

Each mile pushes the AdBlue deeper in. That's why a hop across Horncastle to park beside Stanhope Memorial and a drive of under 25 miles towards Lincoln are such distinct jobs. Let us know about how far it had come.

Our technicians do all of the cleaning where the vehicle has come to a stop, and once your engine has been run there is more of it. Spotted quickly, it very seldom leaves lasting damage.

What does an AdBlue drain on a diesel involve in Horncastle?

Our technicians come to the vehicle, wherever it has stopped around Horncastle: a side street close to Horncastle Library, a drive, a lay-by or a forecourt. What got in, about how much, and whether the engine has been run: our technicians ask before all else, since those shape the job.

Next, emptying your tank right there takes out the polluted diesel along with the AdBlue in one go. A careful flush matters much more with AdBlue than with petrol, since residue won't wash away by itself. Clean diesel goes in once the filter is cleaned — or swapped, when it needs to be — and then your vehicle is tested. The majority of these jobs are a half-hour visit once our technicians turn up, provided the engine hasn't run. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house at night.

Finally, the fuel system is bled with fresh diesel. Whether it is a parking bay outside the nearest station or a driveway around Horncastle, that is where our technicians start the engine and you head off. The test before our engineers leave is that it runs properly on new diesel. We do it all wherever your car has ended up, and it never needs to go to a workshop. Afterwards, you are given paperwork for your insurer: a VAT invoice plus a report from the engineer.

About Horncastle and where it is

Horncastle is a town situated on the River Waring in Lincolnshire, with a population of around 7293 people. Horncastle sits at an elevation of 34 metres, near the villages of Thimbleby and Low Toynton, and is located 17.6 miles from Lincoln.

AdBlue drains in Horncastle and across Lincolnshire

AdBlue jobs in Horncastle go to vans that cover the places near it — Thimbleby, Low Toynton plus Thornton — and much of Lincolnshire beyond, across LN postcodes. If you're near a boundary, or somewhere hard to explain, ring and ask instead of assuming.

Horncastle is a riverside town, and an on-site drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it stands, so it never needs to be moved to us.

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

Every job differs, and so not one fixed price would be fair. Three things shift the price: whether your engine has been running and for how long, how much AdBlue was put in, and where the car is. That last one comes down to whether a van can get to it safely, and an open drive is simpler than a tight space behind St. Mary's.

That's why every call from Horncastle starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it's run. With them, a range shrinks to one firm figure.

You hear that quote by phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront. While the van is on the way, check your insurance: plenty include misfuelling.
