Lower Bourne: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in your diesel tank, the ignition remains off and so does your motor. Water with urea mixed in it: that is AdBlue. It doesn't burn, it does not mix with diesel, and the harm it does begins when the system draws it in. A drain and a thorough flush, done where the car is in Lower Bourne, is generally all AdBlue in a diesel tank needs — if it is caught before the engine has run. Before anything, phone us on 0333 366 0103.

Those opening minutes: AdBlue in the diesel tank around Lower Bourne

To do:

  • Remove your keys, and that prevents anyone turning the power on.
  • Put the hazards on if you are at all near moving traffic.
  • So you can give us which liquid it was and about how much, keep the till receipt or the empty bottle.
  • Give us a postcode starting GU10 3, or whatever street lies closest, and the van finds you directly — so call from wherever you are.

Never do these:

  • No starting your motor — not for a second, not to reposition your vehicle.
  • Plenty of diesels power their fuel pump the moment the ignition goes on, so leave the car off.
  • Adding extra diesel does not help: AdBlue separates out instead of thinning.
  • Even a short way along Grovelands is too far to drive the vehicle.
  • Do not try to drain the car yourself by the roadside.

At a forecourt in Lower Bourne, whether it's the Texaco or another one, ask the staff to help you roll the vehicle away from the petrol pump. If you're on your own drive, leave the vehicle exactly where it sits.

What does AdBlue do in a diesel tank?

AdBlue is made for your exhaust, not the motor. It goes into its own tank and is sprayed into your exhaust gas to clean it. Neither side suits the other: urea does not belong in a pump, and a pump can't deal with urea.

Tipped in with your diesel, it keeps separate instead of mixing — entirely different from fuel. Denser than diesel, it drops and collects underneath it — the very place the intake draws from. Easiest of all: one that got AdBlue in Boundstone overnight and has not been started since. The liquid waits at the base of that tank, untouched — but it will be first through if your engine starts, ahead of any diesel at all.

Two kinds of harm follow from there. What is left when the water goes is urea, which turns into crystals: they settle in tiny passages and clog filters. On top of that, it attacks some metals in a fuel system, and keeps going until it is cleared out. If the AdBlue has reached the pipework, leaving it till morning around Lower Bourne makes it worse. In that tank only, time costs nothing. And there is the water: it brings no lubrication to the parts that need it the most — the injection pump and each injector.

Draining AdBlue from a diesel tank in Lower Bourne

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

Put petrol in a diesel at the BP and you have a fault of thin fuel. No harm comes while it stays put, blended into the diesel — only when your engine works on it.

AdBlue in a diesel is another problem: not thin fuel, but no fuel at all. It can't simply be run through, because it doesn't burn. Nor can it be watered down, since it separates again — and the next tankful will not clear away deposits or corrosion. So the flush matters more with AdBlue, and turning your key "to see", in the heart of Lower Bourne or out in Shortheath, costs more than nearly any other mistake.

As with petrol, there's good news. Not started? Then the AdBlue sits only in the tank, the easiest section of the whole system to empty, wherever the vehicle has stopped in Surrey.

AdBlue in a diesel tank in Lower Bourne: how it ends up there

No one means to do it. The AdBlue filler on plenty of vehicles rests right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Mostly it's not the filling station: someone picks up a bottle driving home and tips it in outside the house.

It tends to happen in a few familiar ways. Midway through the drop-off, the dashboard flags it up, and outside South Farnham School the top-up is rushed. Close to Bourne Grove, someone pours a bottle in at home after work. Or someone new to that flap refills the car after dark, stopped in the car park by The Spotted Cow.

The least known vehicles see it most — rentals, new cars, company cars, and the spare motor of a home with one of each fuel types. Keep it off: that's the first step to the same slip, wherever in Lower Bourne or the remainder of Surrey you are.

Already started your engine with AdBlue in the diesel tank around Lower Bourne?

The AdBlue has left the tank, then. With any running time, it travels to the injection pump and every injector, after passing via your filter and pipework.

You may notice your motor running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Bourne Recreation Ground or halfway across Lower Bourne. No restarting to test: stop when safe, then switch it off. Each start pulls more of that through.

On the M3, under 10 miles from Lower Bourne, the first junction is where to leave, and somewhere safe is where to stop — not carrying on.

Mileage matters: every mile pushes the AdBlue deeper into your system, and so heading towards Winchester, under 25 miles away, makes a much bigger job than hopping across Lower Bourne to the car park by St Martins Hall. Roughly how far it had come is worth telling us.

Wherever the vehicle came to a halt is where all of it gets done, even with more to flush after the motor has been running. Very rarely does it leave lasting damage when it's caught early.

What clearing AdBlue from a diesel involves in Lower Bourne

Wherever it has come to rest around Lower Bourne — a filling station, a lay-by, a driveway, a road by St Martin by the Green — the van travels to the vehicle. Before anything else our technicians ask what was put in, roughly how much, and whether the motor has run, because those replies determine this work.

On the spot, that tank is then drained, and both the contaminated diesel and the urea come out at once. A full flush matters much more after AdBlue than after petrol, because what remains will not wash away by itself. Clean diesel goes in after the filter is flushed — or swapped, if it needs to be — and after that your car is tested. Most of these jobs are a half-hour visit once our technicians turn up, provided your motor has not run. Explosion-proof pumps make a live forecourt safe to work on, and they run quiet enough to spare the neighbours at night.

Bleeding the fuel system with new diesel comes last. You head off as soon as our technicians have started the engine, and it makes no difference whether the car is on a driveway in Lower Bourne or in a space by Farnham. It is checked on fresh diesel to confirm it runs smoothly before our engineers leave. The entire job is done where the car is, so it never has to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come afterwards.

AdBlue drains across Surrey, Lower Bourne included

The Bourne, Middle Bourne and Compton are among the towns near Lower Bourne that the same vans serve, together with most of Surrey beyond, throughout the GU postcode area. Guessing won't help close to a border or somewhere hard to pin down; phone and check.

No moving is needed. In Lower Bourne, a residential suburb, a van that comes to you fits: your car is drained where it stands, be it on a drive, a residential street, a parking area or a forecourt.

Lower Bourne: what AdBlue in a diesel tank costs to fix

Since each callouts vary, a single price would not be fair. The cost moves first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where your car is and whether our van can get to it safely, which is simpler on an open driveway than in a tight gap behind 5th Farnham (Bourne) Scout Group.

Before a quote, not afterwards, each enquiry from Lower Bourne begins with three questions: the fuel, the amount, and whether the engine ran. Those answers narrow a range down to one number.

The quote is quoted during the call, before anyone sets off; settling up comes on the day, by card or by phone, and nothing upfront. Misfuelling cover is part of plenty of insurance policies, so it pays to look at yours before the van gets there.

Lower Bourne: still next to your car?
