Riddings: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into your diesel tank, keep the engine off and keep your ignition off. Water with urea dissolved in it: that is AdBlue. Being water-based, it will not burn and won't blend with diesel; trouble only comes when the pump begins drawing it. If your engine hasn't run yet, AdBlue in a diesel tank is normally emptied and carefully flushed where the car stands around Riddings. Nothing comes before ringing 0333 366 0103.

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

To do:

  • Remove the keys, which stops anyone switching the power on.
  • Hazards on, if moving traffic is anywhere near.
  • Which fluid, and roughly what amount? Hang on to the bottle or the receipt, and our engineers can see.
  • Ring us from where you are. A postcode starting DE55 4, or the name of the nearest street, brings our van to you without a search.

Do not:

  • Not even briefly, and not to shift your car: the motor stays off.
  • The ignition remains off: on many diesels, switching it on is enough to start the pump.
  • AdBlue does not dilute in diesel — it separates out — so adding more diesel won't weaken it.
  • Keep it where it is instead of driving it anywhere, even a short stretch down Alfred Street.
  • Do not try to drain the vehicle yourself by the kerbside.

The staff on duty at any Riddings filling station — the Esso among them — will usually help rolling it clear if you ask. On your own drive, do not touch it at all.

AdBlue in a diesel tank: what it does

The engine is not what AdBlue is made for; your exhaust is. From a separate reservoir it is fed directly to the exhaust, treating what the engine lets out. Nothing in an injection pump is designed for this fluid — and none of that was intended to travel through one.

Fuel mixes; AdBlue, once tipped in, will not. The behaviour is not at all like fuel's. It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup draws fuel from. Simplest of all: a vehicle that had AdBlue in Golden Valley last night and hasn't turned since. The AdBlue waits at the base of the tank, undrawn — but it will be first through once your motor starts, ahead of any diesel at all.

From there it causes two kinds of harm. What is left when the water goes is urea, which turns into crystals: they lodge in tiny channels and block filters. On top of that, it attacks some metals in the fuel system, and carries on till it's flushed out. By daybreak, a car sitting around Riddings with AdBlue through its pipework grows worse; if it is just inside your tank, it doesn't. And there is the water: it brings no protection to the parts that need it the most — the high-pressure pump and each injector.

Draining AdBlue from a diesel tank in Riddings

AdBlue in a diesel: why it's often worse than petrol

An issue of thinned fuel is what you end up with after fuelling a diesel with petrol at the Sainsbury's. It mixes with your diesel, and whilst it's inside the tank it causes no harm; the damage comes from running your motor on it.

AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all. It cannot simply be run through, since it doesn't burn. Whether your vehicle sits in Ironville or the centre of Riddings, firing it up "to see" does more harm with AdBlue than almost any other mistake, and the flush counts for more. The reasons: it won't stay blended, and so diluting it is impossible; and deposits and corrosion outlast the following tankful.

As with petrol, there's good news. Emptying a tank is the simplest part on any fuel system, and with no start-up, the AdBlue remains in it — anywhere around Derbyshire the vehicle has stopped.

AdBlue in a diesel tank in Riddings: how it ends up there

Plenty of vehicles place the AdBlue filler beside the diesel one, now and then behind one flap, and in dim light the two can appear the same. No one intends it. Mostly it is never the forecourt: someone picks up a bottle driving home and tips it in at home.

It tends to take place in a couple of familiar ways. The top-up is hurried outside Riddings Junior School, after the dash lit up with a warning as the kids were taken in. In the evening, a container is tipped in on a driveway near Frederick Street. Else, in dim light outside Queens Head, the vehicle gets topped up by someone using that flap the first time.

The least known vehicles see it most — hire cars, brand-new cars, company ones, and the other motor of a home with both fuels. Wherever across Derbyshire, Riddings included, the slip doesn't change, and neither does the first response: keep it off.

AdBlue in your diesel tank around Riddings, and the motor started?

The AdBlue has left that tank, then. The fuel filter and lines have had it pulled along, and some running takes it on to the injection pump and each injector.

Watch for lumpy running, exhaust smoke, lost power, warnings on your dash, or a cut-out — coming back from Riddings Park, perhaps, or midway across Riddings. Once you safely can, stop then turn everything off — without turning it on again to see. More of that is pulled through with each start.

If you were on the M1, under 3 miles from Riddings, come off at the next junction and stop somewhere safe instead of pressing on.

Hopping across Riddings to the car park by Riddings Park Community Centre is one matter; heading towards Derby, under 15 miles away, is another, because each mile carries the AdBlue further in. So distance matters. About how far it had come is worth telling us.

Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out after the motor has been run. Spotted quickly, it very rarely leaves long-term damage.

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

The car remains where it is, whether that is a street near St James, a drive, a layby or a filling station in Riddings, and the van comes to it. What was put in, roughly the quantity, plus if your engine has been run: our technicians ask before all else, because those decide the job.

Then your tank is drained where your car waits, so the contaminated fuel and the AdBlue come out together. A full flush counts far more with AdBlue than after petrol, since what remains won't wash out by itself. A test of the vehicle follows last, after clean diesel goes in and your filter is flushed or, if necessary, swapped. About half an hour once we arrive is typical for most jobs where the engine hasn't run. The pumping gear is explosion-proof, and so a busy filling station is no issue, and it's quiet enough for a residential street late at night.

Lastly, the system is bled with new diesel. Starting the engine comes next, and then you drive off from where your car is parked, by Alfreton or on a drive in Riddings. The test before our engineers leave is that it runs smoothly on clean diesel. Our technicians do it all wherever the car has ended up, and it never has to be taken to a garage. Your insurer is likely to want an engineer's report and the VAT invoice — each handed over afterwards.

AdBlue drains across Riddings and Derbyshire

Throughout the DE postcode area, the teams taking AdBlue call-outs in Riddings reach most of Derbyshire too, Leabrooks, Somercotes and Codnor Park included. If you are near a boundary, or somewhere hard to describe, ring and ask rather than assuming.

A van that comes to you suits Riddings, a rural village: you have no need to take your vehicle to us, since our engineers drain it on the spot, on a driveway, a side street, a parking area or a forecourt.

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

Each job differs, and so no fixed price is honest. Three things change the cost: whether your engine has been running and for how long, how much AdBlue got in, and where the car is. That last one rests on whether our van can get to it safely, and an open driveway is simpler than a tight spot behind Somerlea Park Centre.

With that reason, every call from Riddings opens by asking the same trio — which fluid got in, how much, whether the engine ran — ahead of any quote. Given those replies, the range narrows to a single firm number.

Before a van heads out, you are told the quote on the phone. Then payment is on the day, by card or by phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we are on the way.
