Walsden: AdBlue in the Diesel Tank? Leave It Off

AdBlue in the diesel tank? Then keep the engine off — and the ignition as well. Urea dissolved in water is all AdBlue is. Not like fuel, it neither burns nor blends, and nothing starts until the motor sucks it round. A drain and a thorough flush, done where the car is around Walsden, is usually all AdBlue in a diesel tank takes — if it is caught before the motor has run. Before anything, ring us on 0333 366 0103.

Your next steps right now, Walsden: AdBlue in the diesel tank

Do:

  • Keys out — then nobody can power anything on.
  • Near moving traffic? So put the hazard lights on.
  • Which product, and about how much amount? Save the bottle or the till receipt, and our engineers will know.
  • Give us a postcode starting OL14 6, or whatever street is closest, and our van finds you straight — so call from wherever you are.

Things not to do:

  • Shifting your vehicle just a short way is no reason to fire up your engine.
  • Many diesels power their fuel pump the instant your ignition comes on, and so leave it off.
  • Adding extra diesel doesn't work: AdBlue settles out rather than thinning.
  • Never drive the car anywhere, not even a short distance down Dampier Street.
  • By the road, don't try draining it yourself.

Ask the people behind the counter to help you roll the car away from the island if you're on a forecourt in Walsden, whether it's the Shell or elsewhere. At home, the car stays exactly where it is.

What does AdBlue do in a diesel tank?

Meant for your exhaust, AdBlue has no business in the motor. Stored in a separate tank, it is squirted into the exhaust stream to treat the fumes. Not one side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea.

It doesn't blend. After it's tipped into the tank, AdBlue acts not at all like diesel. It is heavier than diesel, so it sinks and gathers at the bottom of the tank, which is where the pickup draws fuel from. The first thing the system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Bottomley last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of the tank, and nothing has sucked it in.

It does two kinds of damage from there. It attacks some metals found in fuel components, working on any part it reaches till it's cleared completely. And once the water evaporates, the urea turns into crystals that clog filters and lodge in narrow channels. Where the AdBlue is in the pipework, waiting overnight in Walsden makes things worse. In your tank only, time does nothing. Water protects nothing. The injection pump and every injector depend on diesel flowing past them, so the water part damages them in its own right.

Draining AdBlue from a diesel tank in Walsden

Why AdBlue in a diesel is frequently more major than petrol

Top up a diesel with petrol by mistake over at the Texaco, and the problem is diluted fuel. Harm only comes from driving on it. Mixed into the diesel and left in your tank, it does none.

The issue with AdBlue in a diesel is a totally wrong liquid. It cannot simply be run through, since it doesn't burn. Nor can it be watered down, since it separates again — and the next tankful will not rinse away deposits or corrosion. So the flush matters more with AdBlue, and trying the engine "to see", in the centre of Walsden or out in Shade, does more harm than nearly any other slip.

As with petrol, there's good news. Clearing a tank is the simplest part on any fuel system, and without start-up, the AdBlue remains in it — wherever in West Yorkshire your car sits.

Walsden: how AdBlue ends up in a diesel tank

Plenty of vehicles put the AdBlue filler beside the diesel one, occasionally under a single flap, and in dim light the two may appear identical. No one means it. Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

The ways it occurs are few and familiar. Hurrying, outside Walsden St Peter's CE (VC) Primary School, after a warning lamp flashed on during the school run, a parent refills your car. After work, a bottle goes in on a driveway close to Hollins Road. Otherwise, after dark by Border Rose Inn, the vehicle is refilled by a driver using that flap the first time.

Rented cars, new motors, fleet vehicles, or the second car in a home with one of each: the least familiar cars get it the most. Keep it switched off: that is the first step to the same mistake, wherever in Walsden or the remainder of West Yorkshire you happen to be.

Already started the engine with AdBlue in the diesel tank around Walsden?

Then the AdBlue has left the tank. Your filter and pipework have had it sucked through, and any running carries it on to the injection pump and every injector.

You may notice the engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Birks Wood or halfway across Walsden. Pull over when it is safe. Turn off. Leave the vehicle off instead of testing it again. With each start, more of it is pulled through.

Exit the M62, under 5 miles from Walsden, at the next junction and stop somewhere safe, rather than carrying on.

A quick hop across Walsden to the car park by Walsden Library is one matter; driving towards Bradford, under 25 miles away, is another, because each mile pushes the AdBlue further in. So mileage counts. Roughly how far had it come? Tell us.

Wherever the car came to a stop is where all of it gets done, even with more to rinse out once the engine has been started. Caught soon, it very rarely leaves permanent damage.

Walsden: how AdBlue is emptied from a diesel

Anywhere it has come to rest around Walsden — a filling station, a layby, a driveway, a street by St Peter — our van travels to the vehicle. The job rests on three answers, and our technicians get first — what was put in, the amount, and if your motor has turned over.

Right there, your tank is then drained, and both the contaminated diesel and the urea come out as one. With AdBlue, far more than with petrol, the flush counts: the fuel system is cleaned right through because residue will not wash out unaided. Next, the filter: flushed, or changed if it has to be. After that clean diesel, and then a check of the vehicle. Roughly half an hour on site is usual for most jobs when your motor hasn't run. Explosion-proof pumps mean a live forecourt sensible to work on, and they run quiet enough not to disturb the street at night.

The last step is to bleed your system on new diesel. Whether it's a parking bay at the nearest station or a drive around Walsden, that is where we start the engine and you head off. The test before our engineers leave is that it runs correctly on clean diesel. No workshop is needed at any stage, with the entire job done on the spot. Afterwards, there is paperwork for your insurer: a VAT invoice and a written report from the engineer.

About Walsden, for a moment

Walsden is a suburban area in West Yorkshire, situated near the lakeside and surrounded by wooded areas such as Knowl Wood and Ramsden Wood. Walsden sits at an elevation of 159 metres, approximately 15.6 miles from Bradford, and is characterized by its predominantly terraced housing. Walsden is home to a population of around 1387 residents, who live in close proximity to nearby Gauxholme. Walsden's location allows for easy access to the surrounding countryside and nearby urban centres.

AdBlue drains across Walsden and West Yorkshire

Knowl Wood, Gauxholme and Ramsden Wood are among the places around Walsden that the same vans serve, along with most of West Yorkshire further out, over the OL postcode area. Near a border, or anywhere awkward to pin down? Asking beats assuming, so phone.

A van that comes to you suits Walsden, a residential suburb: there's no need to take your car to us, since our technicians drain it on the spot, on a drive, a side street, a parking area or a forecourt.

Walsden: what AdBlue in a diesel tank costs to fix

There is no honest single price, since the jobs are not the same. Whether the engine has been running, and for how long, comes first in what moves the cost. How much AdBlue got in comes next, and then the position of your car, since an open drive is easier for our van to reach safely than a tight gap behind John Cockroft.

Before a figure, never after, each enquiry from Walsden begins with three questions: the liquid, the quantity, plus if the engine ran. When they are known, a range turns into one firm number.

Quoted by phone before the engineer heads out, the job is settled on the day — card or phone, nothing in advance. Misfuelling cover comes with plenty of insurance policies, so it is worth looking at yours before the van gets there.
