Sandford: AdBlue in the Diesel Tank? Leave It Off

Engine off, ignition off: that is where you start if AdBlue has got into your diesel tank. Chemically, AdBlue is just urea in water. It doesn't burn, it does not mix with diesel, and the harm it does starts when the system draws it in. If the engine hasn't run yet, AdBlue in a diesel tank is generally emptied and carefully flushed where the car stands in Sandford. Phone 0333 366 0103 before you do anything else.

What to do right now, Sandford: AdBlue in your diesel tank

Do:

  • Keys out — then nobody can power anything on.
  • If you're anywhere near moving traffic, put the hazards on.
  • Which fluid, and about what volume? Save the bottle or the receipt, and our engineers can see.
  • Give us a postcode starting BS25 5, or whatever street lies nearest, and our van finds you directly — so ring from wherever you stand.

Do not:

  • Not even for a second, and not to shift the vehicle: your motor stays off.
  • Your ignition stays off: on many diesels, switching it on is enough to start the pump.
  • Do not top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.
  • Never drive the vehicle anywhere, not even a short stretch along Hill Road.
  • Do not try to drain the car yourself by the kerbside.

Ask the people behind the counter to help you roll your car off the island if you're at a forecourt around Sandford, whether it is the the nearest petrol station or elsewhere. At home, your car stays exactly where it was left.

AdBlue in a diesel tank: what it does

The engine isn't what AdBlue is made for; the exhaust is. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Nothing in a fuel pump is made for this liquid — and no part of that was meant to travel that way.

Inside a diesel tank it acts really differently from fuel. It does not mix in. Denser than diesel, it drops and collects below it — the same place the pickup draws from. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Churchill last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in.

It causes two kinds of harm from there. It attacks certain metals used in fuel components, attacking any part it touches till it's removed from your system. And once the water evaporates, the urea forms crystals that clog filters and lodge in narrow passages. Pipes holding AdBlue spell damage overnight for a car sitting around Sandford. Only in your tank, it stays stable. Diesel protects the high-pressure pump and every injector as it flows; water offers none of that, and that is a separate form of damage.

Draining AdBlue from a diesel tank in Sandford

Why is AdBlue in a diesel commonly the bigger issue?

Fill a diesel with petrol in error at the Texaco, and this issue is thinned fuel. It mixes with your diesel, and whilst it is inside that tank it causes no harm; the damage comes from running the motor on it.

With AdBlue in a diesel, the liquid as such is simply the wrong one. Not burning, it can't simply be run through. It does not stay mixed, and so it cannot be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether your car is in Winscombe or the middle of Sandford.

As with petrol, there's good news. If the engine hasn't run, the AdBlue is still in the tank, and that tank is the easiest part of a fuel system to clear, wherever in Somerset the vehicle is standing.

Sandford: how AdBlue ends up in a diesel tank

It's not on purpose. Plenty of vehicles keep the AdBlue cap beside the diesel one, now and then under one flap, and muddling them up is simple in poor light. It mostly occurs outside the house, from a container bought en route home, rather than at the forecourt.

The ways it occurs are few and familiar. The refill is hurried outside Sandford Primary School, after your dash lit up with a warning while the children were dropped off. Close to Nye Road, a driver tips a bottle in on the drive in the evening. Otherwise, after dark by Railway Inn, the vehicle is refilled by someone using that flap for the first time.

The least familiar vehicles get it most — rentals, brand-new ones, company cars, and the spare motor in a family with one of each fuels. An identical slip, an identical first step — leave it switched off — anywhere you are in Sandford or the rest of Somerset.

Already started your engine with AdBlue in your diesel tank around Sandford?

Then the AdBlue has left the tank. Your filter and lines have had it pulled through, and any running time takes it on to the injection pump and every injector.

Maybe returning from Community Sports Field, or part way across Sandford, the motor might run rough, smoke, drop pace, light up your dash or cut out. Pull over when it is safe. Turn off. Keep the car off rather than testing it again. Every start pulls more of that through.

Sandford lies under 3 miles from the M5; if you were on it, leave by the next junction and pull up somewhere safe instead of driving on.

Mileage matters: every mile pushes the AdBlue deeper in, so driving for Wells, under 15 miles away, gives a far larger job than crossing Sandford to the car park by All Saints. Roughly how far it had come is worth telling us.

Once the motor has been run, the flush includes more, and all of it is done where the vehicle has stopped. Very seldom does it leave long-term damage when it's caught soon.

Sandford: how AdBlue is drained from a diesel

A street beside Sandford Village Hall, a drive, a lay-by or a forecourt: anywhere the car has come to rest in Sandford, our technicians come to it. Three replies shape the job, so first our technicians ask what was put in, about what quantity, and whether your motor has turned over.

Then your tank is cleared where your car stands, so the contaminated fuel and the AdBlue come out together. A full flush counts far more with AdBlue than with petrol, since what remains will not clear out by itself. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. Roughly half an hour on site is typical for most jobs where the motor has not run. Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough not to disturb the neighbours at night.

The last step is to bleed your system on fresh diesel. At that point our technicians start the car and you set off, whether from a parking bay by Worle or a drive around Sandford. Before leaving, our technicians make sure it is running smoothly with fresh diesel in. Since the job is done in its entirety where the car is, a garage never comes into it. Your insurer is likely to want an engineer's report and your VAT invoice — both yours once the job is done.

About Sandford and where it is

Sandford is a small village in Somerset, situated on the riverside at an elevation of 26 metres, with detached housing being the predominant type of accommodation. Sandford lies near the villages of Sandford Batch and Towerhead, and is close to Churchill Green. Sandford is located 11.7 miles from the city of Wells and 117.1 miles from London, making it a rural community with a relatively small population of around 555 residents.

Sandford and Somerset: AdBlue drains across the area

AdBlue jobs in Sandford go to vans that serve the places near it — Sandford Batch, Towerhead plus Churchill Green — and most of Somerset further out, across BS postcodes. Ring and ask instead of guessing if you're close to a border, or anywhere tricky to explain.

No towing is needed. In Sandford, a village, a mobile service fits: your vehicle is drained where it stands, whether on a driveway, a residential street, a parking area or a filling station.

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

Not one flat price could be fair, because every job differs. The cost moves first with how long, if at all, the engine has been running, and next with the amount of AdBlue that got in. After that it rests on where the car is and whether our van can reach it safely, which is easier on an open drive than in a tight spot behind Sandford Station Railway Heritage Centre.

That's why each call from Sandford starts with the same three queries, asked before giving a figure, not after: what went in, how much, and if it has run. Those answers turn a range into a straight quote.

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