AdBlue in a Diesel Tank in Crown Hills? Don't Start It

If AdBlue has got into the diesel tank, leave your engine off then leave your ignition off. Urea mixed in water is what AdBlue is. Not like fuel, it neither ignites nor blends, and nothing starts until the motor pulls it through. If your motor has not run yet, AdBlue in a diesel tank is usually drained and carefully rinsed where your car sits around Crown Hills. Call 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in the diesel tank around Crown Hills

Things to do:

  • Keys out — that way nobody can switch anything on.
  • Put the hazard lights on if you're at all near moving traffic.
  • The empty bottle or the receipt shows us the product and the quantity, so don't throw it out.
  • The van finds you fastest with a postcode starting LE5 4, or simply the name of a street nearby, and so phone from the spot.

Don't do these:

  • Not even for a second, and not to roll the car: your engine stays off.
  • The ignition stays off: on many diesels, switching it on is enough to run the pump.
  • Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
  • Even a short distance along Coleman Road is too far to drive the car.
  • Don't try to drain the vehicle yourself by the kerbside.

At a forecourt in Crown Hills, whether it is the Shell or another one, ask the staff to help you push the vehicle away from the pump. Stopped on your own driveway? Then it stays exactly as it is.

What does AdBlue do in a diesel tank?

Made for the exhaust, AdBlue has no place in your motor. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Neither side fits the other: urea doesn't belong in an injection pump, and an injection pump can't take urea.

Poured in with the diesel, it keeps apart instead of blending — entirely different from fuel. The pickup takes fuel from the deepest part of that tank, and that's just where AdBlue settles: being heavier than diesel, it sinks. Simplest of all: a vehicle that got AdBlue in Spinney Hills last night and hasn't been started since. The liquid sits at the base of the tank, untouched — but it will be first through if your engine runs, before any diesel at all.

Two kinds of harm follow from there. What remains once the water evaporates is urea, which forms crystals: they lodge in narrow channels and block filters. On top of that, it eats at some metals in the fuel system, and carries on till it is flushed out. Overnight, a vehicle sitting in Crown Hills with AdBlue in its lines grows worse; if it is just inside your tank, nothing changes. And there's the water: it brings no protection to the components that rely on it most — the high-pressure pump and each injector.

Draining AdBlue from a diesel tank in Crown Hills

Petrol or AdBlue in a diesel: why AdBlue is often worse

An issue of thinned fuel is what you get after fuelling a diesel with petrol from the another forecourt nearby. No damage is done as long as it sits put, blended into your diesel — only once your motor runs on it.

AdBlue in a diesel is another problem: not thin fuel, but no fuel at all. It doesn't burn, so it cannot just be run through. Nor can it be thinned, since it splits back out — and the following tankful will not rinse away deposits or corrosion. So the flush counts more with AdBlue, and trying your engine "to see", in the heart of Crown Hills or out in Thurnby Lodge, does more harm than nearly any other error.

With AdBlue, the good news is no distinct from petrol. Never started? Then the AdBlue waits only in your tank, the easiest section of the entire system to clear, anywhere the car has come to rest in Leicestershire.

How AdBlue ends up in a diesel tank around Crown Hills

After dark, two caps side by side — the AdBlue cap and the diesel one, occasionally under one flap — can appear the same. No one intends it; plenty of designs allow it. A bottle bought when driving home and tipped in at home, instead of at the forecourt, is the typical route.

It tends to occur in a few familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside Rowlatts Mead Primary Academy. A bottle is poured in at the end of the day on a drive just off Barnes Heath Road. Else, in dim light by Treacey's, your vehicle gets refilled by a driver opening that flap the first time.

It comes up the most in a rental, a brand-new vehicle, a fleet car, or the other car in a family with both fuels — the vehicles drivers use least. Keep it off: that's the first step to an identical mistake, anywhere in Crown Hills or the remainder of Leicestershire you happen to be.

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

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

You may notice the engine running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Lily Marriot Garden or halfway across Crown Hills. Once safe, pull over then switch it off — with no restarting to see. More of that is pulled through with each start.

If you were on the M1, under 10 miles from Crown Hills, come off at the next exit and stop somewhere safe instead of pressing on.

Every mile carries the AdBlue further in. That is why crossing Crown Hills to park near Lily Marriott Stone and a drive of under 3 miles for Leicester are such different jobs. Let us know roughly how far it had come.

There is more to clean out once the motor has been run, and our engineers do all of it where the vehicle has ended up. Long-term damage is very uncommon if it's spotted quickly.

What does an AdBlue drain on a diesel involve around Crown Hills?

A street by Coleman Neighbourhood Centre, a drive, a layby or a forecourt: wherever the car has stopped in Crown Hills, our technicians travel to it. The job depends on three replies, which our technicians ask for before all else — which fluid was put in, the quantity, and whether your motor has run.

Then the tank is emptied where your car waits, and so the polluted fuel and the AdBlue come out together. Residue from AdBlue will not flush away unaided, so the fuel system gets a careful flush, which counts far more here than for petrol. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Not run? Then count on roughly half an hour once we are there for most jobs. Our pumping gear is explosion-proof, so a busy filling station is no problem, and it's quiet enough for a residential street after dark.

Finally, the fuel system is primed with new diesel. Firing it up comes next, and then you head off from where your car is parked, outside Leicester or on a drive in Crown Hills. Before leaving, our technicians check it is running smoothly with new diesel in. Since the job is done in full where the vehicle is, a garage never comes into it. At the end, you are given the paperwork for the insurer: a VAT invoice plus a written report from the engineer.

Crown Hills and Leicestershire: AdBlue drains across the area

AdBlue jobs around Crown Hills go to vans that serve the places near it — North Evington, Evington as well as Humberstone — and most of Leicestershire beyond, across LE postcodes. Assuming won't help by a border or somewhere tricky to describe; phone and check.

Crown Hills is a residential suburb, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it sits, so it never needs to be moved to us.

Crown Hills: what AdBlue in a diesel tank costs to fix

No flat price could be fair, because every job is different. The price shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that was put in. After that it rests on where the vehicle is and whether a technician can get to it safely, which is easier on an open drive than in a tight space behind St Chad.

Which fluid got in, how much, plus if the engine ran: every Crown Hills call begins with exactly those, before any quote, not after. Their replies shrink a range right down to one figure.

The price is quoted during the call, before anyone leaves; payment comes on the day, by card or by phone, with nothing upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours while we are on the way.
