St Annes: AdBlue in the Diesel Tank? Leave It Off

Motor off, ignition off: that is how you begin if AdBlue has got into the diesel tank. In plain terms, AdBlue is simply urea in water. As it is water-based, it won't burn and never combines with diesel; trouble only comes when the pump starts pulling it. A drain and a thorough flush, done where the vehicle is in St Annes, is usually all AdBlue in a diesel tank takes — if it's caught before the engine has run. Before anything, ring us on 0333 366 0103.

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

Things to do:

  • Keys out — that way nobody can switch anything on.
  • Close to moving traffic? Then put your hazards on.
  • Which product, and roughly what volume? Hang on to the bottle or your receipt, and our engineers will know.
  • Give us a postcode starting BS4 4, or whatever street is closest, and our van reaches you directly — so call wherever you are.

Never do these:

  • Not even briefly, and not to roll the car: your motor remains off.
  • The ignition stays off: on lots of diesels, switching it on is enough to run your pump.
  • No more fuel added. The AdBlue won't mix, and so it is wasted.
  • Never drive the car anywhere, not even a short distance along Langton Court Road.
  • Beside the road, do not attempt emptying it yourself.

On a forecourt in St Annes, whether it's the Sainsbury's or another one, ask the attendants to help you roll the vehicle clear of the petrol pump. Parked on your own driveway? Then it stays just as it is.

What does AdBlue do in a diesel tank?

Not your engine but the exhaust is where AdBlue belongs. Kept in a separate tank, it is squirted into the exhaust to clean the gases. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Tipped in with your diesel, it stays apart rather than blending — quite different from fuel. It is heavier than diesel, so it sinks and collects at the bottom of the tank, which is where the pickup sucks fuel from. Simplest of all: one that had AdBlue in St Philips Marsh overnight and has not been started since. The liquid waits at the base of that tank, undrawn — but it will be the first thing through if your engine starts, ahead of any diesel at all.

Once it is drawn in, the harm takes two forms. What is left once the water evaporates is urea, which turns into crystals: they settle in narrow channels and clog filters. On top of that, it attacks certain metals in a fuel system, and carries on till it's flushed out. Pipes carrying AdBlue mean harm overnight for a car sitting in St Annes. Only in your tank, it stays the same. Then there is the water: it offers no protection to the parts that need it most — the high-pressure pump and every injector.

Draining AdBlue from a diesel tank in St Annes

Why is AdBlue in a diesel frequently the bigger problem?

A problem of thin fuel is what you end up with from filling a diesel with petrol from the Shell. Harm just comes from running on it. Mixed into your diesel and left in that tank, it does none.

AdBlue in a diesel is an issue of the wrong substance altogether. It doesn't burn, and so it cannot just be run through. Whether your car sits in Conham or the centre of St Annes, firing it up "to see" does more harm in this case than nearly any other slip, and the flush counts for more. The reasons: it won't stay blended, and so watering it down is impossible; and crystals and corrosion survive the next fill.

The same good news holds as with petrol. Anywhere in Bristol the car has stopped, an unstarted motor leaves the AdBlue yet in the tank: the easiest bit of a fuel system to clear.

How AdBlue ends up in a diesel tank in St Annes

It is not on purpose. Many vehicles keep the AdBlue cap beside the diesel inlet, occasionally behind one flap, and mixing them up is simple after dark. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.

It tends to occur in a couple of familiar ways. Rushing, outside St Anne's Infant School, after a warning light flashed on during the school run, someone tops up the vehicle. Someone pours the bottle in outside their house, just off Maple Road, as the day ends. Or a driver unfamiliar with that flap tops up your car after dark, stopped in the car park outside Langton Court Hotel.

The least known vehicles get it most — rentals, brand-new cars, company cars, and the other car of a home with both fuels. Leave it off: that is the first response to an identical slip, anywhere in St Annes or the remainder of Bristol you are.

Already started the engine with AdBlue in the diesel tank in St Annes?

In that case, the AdBlue is no longer in the tank. It has been sucked through your filter and the lines, and if your engine ran for any time, it has reached the high-pressure pump and your injectors.

Rough running, smoke, lost power, dashboard lights or stalling: any might appear, maybe part way across St Annes or coming back from Saint Anne Park. Stop as soon as it is safe, switch off, and do not restart the car to check. With each start, more of it is pulled through.

St Annes lies under 3 miles from the M32; if you were on it, leave by the first junction and pull up safely rather than driving on.

Hopping across St Annes to the car park by Dame Eva Turner is one matter; driving towards Bristol, under 3 miles away, is something else, since every mile pushes the AdBlue further in. So mileage counts. Tell us roughly how far it had come.

Wherever the car came to a halt is where all of it gets done, even with more to rinse out after the engine has been run. When it is noticed soon, permanent damage is very rare.

Draining AdBlue in a diesel around St Annes: what it takes

A street beside St. Anne's Church, a drive, a lay-by or a forecourt: wherever the vehicle has come to rest around St Annes, our technicians come to it. The job rests on three answers, which we ask for before all else — what got in, the amount, and whether your motor has turned over.

Next, emptying your tank on the spot takes out the contaminated diesel and the AdBlue together. Your system is rinsed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. After that, the fuel filter: cleaned, or changed if it must be. Then clean diesel, and then a check of your vehicle. Most of these jobs are a half-hour job once our engineers get there, provided the motor hasn't run. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house after dark.

Priming the system with fresh diesel comes last. Firing it up comes next, and then you set off from where the car is parked, outside Lawrence Hill or on a driveway in St Annes. Before we leave, our engineers make sure it is running properly with fresh diesel in. No garage is required at any point, with the entire job done on the spot. Your insurer is likely to want an engineer's report and your VAT invoice — each handed over afterwards.

What AdBlue in a diesel tank costs to put right around St Annes

There's no fair single quote, since the jobs are not the same. The cost moves first with how long, if at all, your engine has been running, and next with the amount of AdBlue that got in. After that it turns on where the car is and whether a technician can reach it safely, which is easier on an open drive than in a tight gap behind St Annes Well.

Before any figure, not afterwards, every enquiry from St Annes begins with the same three checks: the fuel, the quantity, plus if it ran. With those replies, the range shrinks to a single fixed number.

Our price is given on the call, before anyone sets off; payment happens on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
