Whitchurch: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into your diesel tank, keep the engine off then leave your ignition off. In plain terms, AdBlue is simply urea in water. The trouble starts once it is pulled through the lines — it won't burn, and it will not blend with diesel. Caught before your motor has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is in Whitchurch. Call 0333 366 0103 before you do anything else.

Whitchurch, AdBlue in the diesel tank: what to do at once

Things to do:

  • So no one can turn your ignition on, pull your keys out.
  • Hazards on, if moving traffic is anywhere close.
  • The empty bottle or the receipt tells us the fluid and the amount, so do not bin it away.
  • Ring us from where you are. A postcode starting RG28 7, or the name of the nearest street, brings the van to you without a search.

Don't do these:

  • Not even briefly, and not to shift the car: the engine remains off.
  • Switching your key to ignition alone starts the pump running on plenty of diesels. Skip it.
  • Adding extra diesel does not help: AdBlue settles out instead of thinning.
  • Leave it where it is rather than driving it anywhere, even a short stretch down Church Street.
  • Beside the road, don't try emptying it yourself.

The attendants on duty at any Whitchurch forecourt — the Whitchurch Filling Station among them — will usually help pushing it clear if you ask. Stopped on your own drive? Then it stays exactly as it is.

What AdBlue does in a diesel tank

The motor isn't what AdBlue is made for; your exhaust is. Kept in a dedicated tank, it's squirted into the exhaust to treat the gases. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Fuel mixes; AdBlue, after tipped in, won't. Its behaviour is not at all like fuel's. The intake sucks fuel from the lowest part of your tank, and that's precisely where AdBlue settles: being heavier than diesel, it sinks. Once your pump runs, the AdBlue is top of the list to go through. Before then it sits beneath the diesel, which is how a vehicle filled in Laverstoke last night and never started stays the simple one, provided no one touches your key.

It does two kinds of harm from there. What remains once the water goes is urea, which forms crystals: they settle in narrow passages and clog filters. Worse, it eats at some metals in the fuel system, and keeps going until it's cleared out. A motor left standing around Whitchurch with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Water protects nothing. The injection pump and each injector depend on diesel running through them, so the water content harms them by itself.

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

Top up a diesel with petrol in error at the Esso, and this issue is thinned fuel. Blended through your diesel and left unused, it's harmless for now; running your engine does the harm.

The trouble with AdBlue in a diesel is a completely unsuitable substance. Because it does not burn, running it through is not an option. It doesn't stay mixed, and so it can't be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your motor "to see" costs more here than almost anywhere else, whether the car is in Hurstbourne Priors or the middle of Whitchurch.

The same good news holds as with petrol. Never run? Then the AdBlue waits only in the tank, the easiest section of the whole system to empty, wherever the vehicle has come to rest around Hampshire.

AdBlue in a diesel tank around Whitchurch: how it ends up there

Plenty of cars place the AdBlue cap beside the diesel cap, now and then under a single flap, and in dim light the two may look the same. Nobody means it. Mostly it is never the filling station: someone buys a bottle driving home and tips it in outside the house.

Mostly, it takes place in one of a couple of familiar ways. The top-up gets hurried outside Whitchurch Church of England Primary School, because your dash flashed with a warning while the children were taken in. Close to B3400, a driver pours a container in at home after work. One more pattern: dim light, the car park outside Kings Arms, and someone using that flap the first time.

The least known vehicles get it the most — hire cars, brand-new cars, fleet ones, and the other motor in a home with both fuel types. Wherever you're in Whitchurch or the rest of Hampshire, it is the same slip and the same first answer: leave it off.

Started the engine with AdBlue in the diesel tank in Whitchurch?

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

Expect lumpy running, exhaust smoke, falling power, lights on the dash, or a cut-out — returning from Kingsley Park, say, or part way across Whitchurch. Stop as soon as it is safe, switch off, and do not restart it to check. Each start pulls more of it through.

Whitchurch lies under 10 miles from the M3; if you were on it, exit by the first junction and stop somewhere safe rather than driving on.

A quick hop across Whitchurch to the car park by Whitchurch Town Hall is one thing; heading for Winchester, under 15 miles away, is something else, since every mile pushes the AdBlue deeper in. So distance counts. Let us know about how far it had come.

Once the motor has been started, the flush covers more, and all of it is done where the car has ended up. Lasting damage is very unusual if it's spotted early.

What draining AdBlue from a diesel involves around Whitchurch

A street by Whitchurch Silk Mill, a drive, a lay-by or a forecourt: anywhere the car has come to rest in Whitchurch, our engineers travel to it. Three replies shape the job, so first we ask what went in, roughly the amount, plus whether the engine has run.

Next, draining that tank right there removes the contaminated diesel along with the AdBlue in one go. What remains from AdBlue won't flush out by itself, so the whole system gets a careful flush, which counts far more here than with petrol. A test of your car comes last, after fresh diesel goes in and your filter gets cleaned or, where necessary, swapped. If the engine hasn't run, the majority of jobs take about half an hour once our technicians are there. Our equipment is explosion-proof, and so a busy forecourt is no issue, and it is quiet enough for a residential street late at night.

The final step is to bleed the system on fresh diesel. You head off as soon as our technicians have fired it up, and it makes no difference whether the vehicle is on a drive in Whitchurch or in a bay outside Whitchurch (Hampshire). Before we leave, we confirm it is running properly with clean diesel in. We do it all wherever the vehicle has stopped, and it never needs to be taken to a workshop. Your insurer is likely to want an engineer's report and your VAT invoice — each handed over once this job is done.

Whitchurch is located approximately 11.7 miles from Winchester and 55.7 miles from London, making it a commuter town with a population of around 5291 residents.

AdBlue drains around Whitchurch and across Hampshire

Lynch Hill, Tufton and Freefolk are among the places around Whitchurch that the same teams reach, along with much of Hampshire beyond, over the RG postcode area. Guessing doesn't help close to a border or somewhere tricky to pin down; ring and ask.

Anywhere your car stands — your driveway at home, a side street, a parking area, a forecourt — our engineers drain it on the spot, with no need to take it to us; that suits Whitchurch, a riverside town, well.

Whitchurch: what AdBlue in a diesel tank costs to fix

There's no honest single price, because the jobs are not the same. Whether your engine has been running, and for how long, comes first in what moves the price. How much AdBlue got in comes next, and then the location of the vehicle, because an open driveway is easier for a van to reach safely than a tight space behind Whitchurch Library.

For that in mind, each call from Whitchurch begins by asking the same trio — which fluid got in, how much, whether the engine ran — ahead of a quote. Their answers shrink the range down to one number.

You hear that price on the phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront. While our engineer is on the way, check your insurance: plenty cover misfuelling.
