Whitecross: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into the diesel tank, leave your engine off and leave the ignition off. Chemically, AdBlue is simply urea in water. The harm starts once it is pulled through your pump — it will not burn, and it will not combine with diesel. A drain and a thorough flush, done where your car is in Whitecross, is usually all AdBlue in a diesel tank needs — if it's caught before your motor has run. Ring 0333 366 0103 before you do anything else.

Whitecross, AdBlue in your diesel tank: what to do straight away

To do:

  • Take your keys out, and so nobody switches the ignition on.
  • If you are anywhere close to moving traffic, put the hazard lights on.
  • So you can tell us which liquid it was and roughly what quantity, keep the receipt or the empty bottle.
  • The van locates you fastest with a postcode starting WA5 1, or simply the name of a street close by, and so call from the spot.

Things not to do:

  • Not even briefly, and not to shift your vehicle: the engine stays off.
  • Plenty of diesels power their fuel pump the instant your ignition goes on, and so leave the car off.
  • Adding extra diesel doesn't work: AdBlue separates out instead of blending.
  • Even a short stretch up Delamere Street is too far to drive it.
  • Draining the tank on your own by the road is not worth trying.

On a forecourt in Whitecross, whether it is the Texaco or another one, ask the staff to help you roll your car away from the petrol pump. If you are on your own drive, leave the car precisely where it sits.

What does AdBlue do in a diesel tank?

The engine is not what AdBlue is made for; your exhaust is. Stored in a separate tank, it is squirted into the exhaust to treat the gases. No part in a fuel pump is designed for this liquid — and none of that was meant to travel that way.

It doesn't blend. After it is tipped into a tank of diesel, AdBlue acts not at all like fuel. The intake takes fuel from the deepest part of that tank, and that is just where AdBlue settles: as it is heavier than diesel, it sinks. Simplest of all: one that had AdBlue in Sankey Bridges overnight and hasn't turned since. The liquid sits at the foot of your tank, undrawn — though it will be the first thing through if your engine runs, before any diesel at all.

After it's pulled in, the damage takes two forms. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, and so it keeps working on the components it hits for as long as it stays there. Pipes carrying AdBlue mean damage by morning for a car parked in Whitecross. Just in your tank, it stays the same. The water in it causes damage of its own: the high-pressure pump and the injectors rely on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Whitecross

Why is AdBlue in a diesel regularly the bigger problem?

Top up a diesel with petrol in error at the Tesco, and this problem is thinned fuel. Damage only comes from driving on it. Blended into the diesel and sitting inside your tank, it causes nothing.

AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all. Since it doesn't burn, running it through is not an option. Crystals and corrosion stay through the next fill, and AdBlue separates again out of your diesel, so watering it can't help. Hence the flush counts more, and turning the key "to see" costs more with AdBlue than nearly any other slip — in Old Hall or the heart of Whitecross alike.

The same good news holds as with petrol. Wherever around Cheshire the vehicle has come to rest, an unstarted motor means the AdBlue still in the reservoir: the easiest bit of a fuel system to empty.

How AdBlue ends up in a diesel tank around Whitecross

After dark, two caps side by side — the AdBlue one and the diesel cap, occasionally behind one flap — can appear the same. Nobody means it; plenty of layouts invite it. It mostly occurs at home, from a container bought en route home, not at the forecourt.

The ways it takes place are few and familiar. A warning light comes on during the school run, and the top-up happens in a hurry outside Warrington St Barnabas CofE Primary School. In the evening, a container goes in on a driveway close to Leicester Street. Else, in dim light by The Hatter, your car is refilled by a driver opening that flap for the first time.

It comes up most in a hire car, a brand-new vehicle, a fleet vehicle, or the other vehicle of a family with one of each fuels — the cars people use least. An identical slip, an identical first response — keep it switched off — anywhere you are in Whitecross or the rest of Cheshire.

Whitecross: started the engine with AdBlue in the diesel tank?

The AdBlue has left that tank, then. It's been sucked through the fuel filter and the lines, and if the engine ran for any time, it has reached your high-pressure pump and the injectors.

Rough running, smoke from the exhaust, lost power, dashboard lights or cutting out: any may show up, maybe part way across Whitecross or coming back from Sankey Recreation Ground. When you safely can, pull over then turn it off — without turning it on again to see. With each start, more of that is pulled through.

On the M62, under 3 miles from Whitecross, the first junction is where to leave, and somewhere sensible is where to park — not driving on.

Every mile pushes the AdBlue further in. That's why a hop across Whitecross to park beside Saint Barnabas and a drive of under 15 miles towards Salford are such distinct jobs. Roughly how far had it come? Tell us.

There is more to clean out once the motor has been started, and we do all of it where your car has stopped. Lasting damage is very rare if it is spotted quickly.

Clearing AdBlue in a diesel in Whitecross: what it takes

A road by Mother and the Babe, a driveway, a layby or a forecourt: anywhere your vehicle has come to rest around Whitecross, our engineers travel to it. Before anything else we ask what got in, about how much, and whether the motor has run, because those answers determine this work.

Next, draining the tank right there removes the contaminated diesel along with the AdBlue in one go. Your system is flushed thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. After that, the fuel filter: cleaned, or replaced if it has to be. Then fresh diesel, then a check of the car. About half an hour on site is typical for most jobs when the motor hasn't run. Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough to spare the street at night.

Fresh diesel goes in to bleed the fuel system, and that is the final step. Firing it up comes next, and then you head off from where the car is parked, outside Warrington Bank Quay or on a drive around Whitecross. Before we go, we confirm it is running properly with new diesel in. We do it all wherever your car has ended up, and it never has to be taken to a workshop. At the end, there is the paperwork for the insurer: a VAT invoice and a written report from the engineer.

AdBlue drains in Whitecross and across Cheshire

AdBlue jobs in Whitecross are passed to vans that cover the towns around it — Bank Quay, Hood Manor plus Bewsey — and most of Cheshire further out, throughout WA postcodes. Close to a boundary, or anywhere tricky to pin down? Asking is better than assuming, and so phone.

No towing is needed. In Whitecross, a residential suburb, a van that comes to you works: your vehicle is drained where it stands, be it in a drive, a side street, a parking area or a forecourt.

Whitecross: what AdBlue in a diesel tank costs to fix

There is no honest single price, since the jobs aren't the same. Whether your engine has been running, and for how long, comes first in what changes the cost. How much AdBlue was put in comes next, and then the location of the car, since an open driveway is simpler for a technician to get to safely than a tight spot behind Whitecross Community Centre.

Before any figure, never after, each enquiry from Whitecross opens with three questions: the liquid, the quantity, and if the engine ran. Once those are known, a range becomes a single fixed figure.

Our quote is given during the call, before anyone leaves; settling up comes on the day, by card or by phone, and nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van gets there.

Whitecross: still beside the vehicle?

Then, the best thing to do with your vehicle is to not touch it. Ignition off, engine off, keys out. Tell us it was AdBlue, roughly what quantity, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, in Whitecross or anywhere in Cheshire.
