Crompton Fold: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has got into the diesel tank, keep the engine off then keep your ignition off. Water with urea mixed in it: that is AdBlue. The trouble starts once it's pulled through your lines — it will not burn, and it won't combine with diesel. If your motor has not run yet, AdBlue in a diesel tank is normally drained and carefully rinsed where the vehicle sits in Crompton Fold. Phone 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in your diesel tank around Crompton Fold

To do:

  • Remove your keys, and that prevents anyone turning the power on.
  • Put your hazards on if you are at all close to moving traffic.
  • Which product, and roughly how much quantity? Save the bottle or the receipt, and our engineers can see.
  • Call us from where you are. A postcode starting OL2 8, or the name of the closest street, gets our van to you without a search.

Don't do these:

  • No starting the motor — not for a second, not to shift your car.
  • Don't switch your ignition on. On many diesels that alone runs the fuel pump.
  • No extra fuel on top. The AdBlue will not mix, and so it is wasted.
  • Leave the car where it is rather than driving it anywhere, even a short stretch down Cliff Hill Road.
  • No emptying it yourself, at all, on the verge.

The attendants on duty at any Crompton Fold forecourt — the Shell among them — will usually lend a hand rolling it aside if you ask. On that drive, the car remains just where it was left.

What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not your engine. From a separate tank it is fed straight to your exhaust, cleaning what the motor emits. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Fuel mixes; AdBlue, once poured in, won't. The behaviour is nothing like diesel's. Heavier than diesel, it sinks and pools below it — the same place the pickup draws from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Black Clough last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.

Two kinds of harm follow from there. Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filter elements and tiny channels; meanwhile, since it eats at some metals, each part it touches keeps suffering for as long as it remains in there. Where the AdBlue has reached the lines, waiting overnight around Crompton Fold leaves things worse. In that tank only, waiting does nothing. Water protects nothing. The high-pressure pump and each injector depend on diesel flowing through them, so the water part damages them in its own right.

Draining AdBlue from a diesel tank in Crompton Fold

Why is AdBlue in a diesel regularly the bigger fault?

Fill a diesel with petrol by mistake at the Esso, and this problem is diluted fuel. It mixes with your diesel, and whilst it's inside your tank it causes no damage; the harm comes from running your motor on it.

The trouble with AdBlue in a diesel is a totally unsuitable liquid. Since it does not burn, running it through is not an option. Nor can it be watered down, because it separates again — and the next fill won't rinse away deposits or corrosion. So the flush counts for more with AdBlue, and trying your engine "to see", in the centre of Crompton Fold or out in Wood End, costs more than almost any other mistake.

The good news is the same as with petrol. Clearing a tank is the simplest part on any fuel system, and with no running, the AdBlue stays in there — wherever in Greater Manchester your vehicle has stopped.

AdBlue in a diesel tank in Crompton Fold: how it ends up there

Plenty of motors put the AdBlue filler beside the diesel cap, now and then under a single flap, and after dark the two may look identical. Nobody means it. A bottle bought while driving home and poured in outside the house, rather than at the filling station, is the usual route.

Usually, it takes place in one of a few familiar ways. The refill is hurried outside Buckstones Primary School, after the dash flashed with a warning while the children were dropped off. A bottle is poured in at the end of the day on a drive just off Buckstones Road. One more pattern: dim light, a pub car park outside The Shay Wake, and someone using that flap for the first time.

Hired motors, new vehicles, fleet vehicles, or the spare car in a home with both fuels: the least familiar cars see it the most. Anywhere in Greater Manchester, Crompton Fold as well, the mistake does not change, and nor does the first step: leave it switched off.

AdBlue in the diesel tank in Crompton Fold, and the engine started?

Then that tank is no longer where the AdBlue is. Via the filter, along the lines, and — with any running — into the injection pump and each injector: that's where it has gone.

Lumpy running, smoke, dropping power, dashboard lights or stalling: any may appear, maybe midway across Crompton Fold or coming back from Dunwood Park. Pull over when safe. Switch off. Keep the vehicle off instead of testing it again. Each start pulls more of it through.

Leave the M62, under 3 miles from Crompton Fold, by the first junction and park somewhere safe, not carrying on.

How far it went matters. A couple of hundred yards across Crompton Fold to the car park by St Saviour's Mission Church is a very different job from a run towards Manchester, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile. Tell us roughly how far it had come.

Our engineers do all of the rinsing where the vehicle has come to a stop, and once your engine has been run there is more of it. Very rarely does it leave long-term damage when it is caught quickly.

What does an AdBlue drain on a diesel involve around Crompton Fold?

The car stays put, whether that is a street near Shore Edge Methodist Church, a drive, a layby or a forecourt in Crompton Fold, and our van travels to it. Before anything else our technicians ask what was put in, roughly how much, and whether the motor has run, because those replies decide the work.

Then the tank is emptied where the car stands, and so the tainted fuel and the AdBlue come out together. With AdBlue, far more than with petrol, flushing counts: the whole system is flushed right through since residue will not wash away by itself. Clean diesel goes in after the filter is flushed — or replaced, if it needs to be — and after that the vehicle is tested. Engine not run? In that case expect roughly half an hour once we are there for most jobs. The equipment is explosion-proof, so a busy filling station is no fault, and it is hushed enough for a residential street after dark.

New diesel goes in to bleed the system, and that's the last step. After that we start the car and you head off, whether from a parking bay by Rochdale or a drive around Crompton Fold. Before leaving, our engineers make sure it is running smoothly with fresh diesel in. Because the job is done in full where your car is, a workshop never comes into it. You get a VAT invoice and an engineer report later on, which is what insurers ask for.

AdBlue drains across Crompton Fold and Greater Manchester

Shore Edge, Jubilee and Goats are among the towns around Crompton Fold that the same vans serve, along with most of Greater Manchester further out, throughout the OL postcode area. Close to a boundary, or anywhere tricky to pin down? Checking beats assuming, and so phone.

Wherever your vehicle stands — your driveway at home, a residential street, a car park, a filling station — our technicians empty it on the spot, with no need to bring it to us; which suits Crompton Fold, a residential suburb, well.

Crompton Fold: what AdBlue in a diesel tank costs to fix

Not one flat figure would be fair, because every job is different. Three things shift the price: whether the motor has been running and for how long, how much AdBlue went in, and where your car is. That last one turns on whether a van can get to it safely, and an open drive is easier than a tight space behind Crompton Waterfall.

Ahead of any figure, never after, every call from Crompton Fold opens with three checks: the fuel, the quantity, plus whether it ran. Once they are answered, a range turns into a single fixed figure.

Before a van heads out, you hear the price by phone. Then payment is on the day, by card or by phone, with nothing upfront. While our engineer is travelling, dig out your policy: plenty include misfuelling.
