Blackfell: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has gone into your diesel tank, leave the motor off and keep the ignition off. Water with urea mixed in it: that's AdBlue. The harm starts once it's pulled through your lines — it will not burn, and it won't combine with diesel. A drain and a thorough flush, done where the vehicle is in Blackfell, is generally all AdBlue in a diesel tank needs — if it is caught before your engine has run. First, call us on 0333 366 0103.

AdBlue in your diesel tank in Blackfell: the first few minutes

Do:

  • Take your keys out, so no one switches the ignition on.
  • Hazards on, if moving traffic is anywhere close.
  • The empty bottle or the receipt tells us the fluid and the amount, and so do not throw it out.
  • Tell us a postcode starting NE37 1, or whichever street is nearest, and the van reaches you directly — so call from wherever you are.

Not to do:

  • Moving your vehicle just a short way is no reason to fire up the engine.
  • Turning your key to ignition alone sets your pump going on plenty of diesels. Avoid it.
  • Pouring in more diesel doesn't work: AdBlue settles out instead of blending.
  • Leave the vehicle where it is instead of driving it anywhere, even a short stretch down Knoulberry Road.
  • No emptying it yourself, either, on the verge.

Get the people behind the counter to help you roll the car off the pumps if you're on a forecourt in Blackfell, whether it's the the nearest petrol station or elsewhere. If you're on your own drive, leave the vehicle just where it is.

AdBlue in a diesel tank, and what it does there

Meant for the exhaust, AdBlue has no business in your motor. Its own reservoir holds it, and from there it's fed into your exhaust, where it cleans the fumes. Nothing inside a fuel pump is made for this liquid — and no part of that was meant to go that way.

Tipped in with the diesel, it keeps separate rather than blending — quite unlike fuel. The pickup takes fuel from the deepest part of your tank, and that's exactly where AdBlue ends up: as it is denser than diesel, it sinks. Once the pump runs, the AdBlue is top of the list to be pulled through. Before then it waits underneath your diesel, and that is why a vehicle topped up in Town Centre last night and never switched on stays the straightforward one, as long as no one touches your key.

Two kinds of harm follow from there. What remains once the water goes is urea, which turns into crystals: they lodge in tiny channels and block filters. On top of that, it attacks some metals in the fuel system, and carries on until it is flushed out. Overnight, a vehicle parked in Blackfell with AdBlue through its pipework gets worse; where it's only inside the tank, nothing changes. And there's the water: it brings no protection to the parts that need it the most — the high-pressure pump and every injector.

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

Top up a diesel with petrol in error at the Sainsbury's, and this problem is diluted fuel. No damage is done as long as it stays put, blended into the diesel — only once your motor runs on it.

With AdBlue in a diesel, the liquid as such is simply the wrong one. It cannot simply be run through, since it doesn't burn. Whether your vehicle is in Washington or the centre of Blackfell, firing it up "to see" costs more with AdBlue than almost any other slip, and the flush matters for more. Why: it won't stay blended, and so watering it down fails; and crystals and corrosion outlast the next fill.

The same good news applies as with petrol. Never run? Then the AdBlue sits just in that tank, the easiest bit of the whole system to clear, anywhere your vehicle has come to rest around Tyne and Wear.

How AdBlue ends up in a diesel tank around Blackfell

No one means to do it. The AdBlue filler on plenty of motors waits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. A bottle bought when heading home and tipped in at home, instead of at the forecourt, is the usual route.

A couple of familiar ways account for the majority of them. Hurrying, outside Blackfell Primary School, after a warning light flashed on during the school run, someone tops up the car. Someone pours the container in outside their house, just off Highheath, as the day ends. Or the car is topped up in the car park outside The Honest Boy, in poor light, by somebody who has never opened that flap before.

It crops up most in a hire car, a brand-new vehicle, a company vehicle, or the spare car in a home with one of each fuels — the cars people know least. Wherever you're around Blackfell or the rest of Tyne and Wear, it's the same error and the same first answer: leave the vehicle off.

Started the motor with AdBlue in the diesel tank in Blackfell?

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

Lumpy running, smoke from the exhaust, dropping power, dashboard warnings or cutting out: any might show up, perhaps midway across Blackfell or returning from Albany Park. Stop as soon as it is safe, switch off, and don't restart the car to check. Each start pulls more of it through.

On the A194(M), under a mile from Blackfell, the next junction is where to exit, and somewhere safe is where to stop — not carrying on.

A quick hop across Blackfell to the car park by St John Boste is one thing; driving towards Newcastle upon Tyne, under 10 miles away, is another, since every mile carries the AdBlue further in. So mileage counts. Roughly how far had it come? Tell us.

There's more to rinse out once your engine has run, and our engineers do all of it where the vehicle has ended up. Long-term damage is very rare when it's caught early.

Draining AdBlue in a diesel in Blackfell: what it takes

A street beside Oxclose Church, a driveway, a layby or a forecourt: wherever the car has come to rest around Blackfell, our engineers travel to it. Three replies decide the work, so before anything else our technicians ask which fluid went in, roughly what quantity, and if the engine has run.

The contaminated diesel and the urea come out together when your tank is emptied, right there. A careful flush counts far more after AdBlue than with petrol, because residue will not clear out on its own. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. If the motor hasn't run, most jobs take about half an hour once our technicians arrive. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house after dark.

The final step is to bleed the fuel system on fresh diesel. At that point our engineers start the car and you set off, whether from a parking space by Heworth or a driveway in Blackfell. Our engineers check it runs correctly on new diesel before we leave. No garage is needed at any stage, with the entire job done then and there. Insurers ask for a VAT invoice and an engineer report, and both come afterwards.

AdBlue drains around Blackfell and across Tyne and Wear

Albany, Oxclose and North Side are among the places around Blackfell that the same teams reach, along with most of Tyne and Wear beyond, over the NE postcode area. Phone and ask instead of guessing when you are close to a county line, or somewhere awkward to explain.

Anywhere the car 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 take it to us; which suits Blackfell, a residential suburb, well.

AdBlue in a diesel tank in Blackfell: the cost of fixing it

Every job differs, and so not one fixed price is fair. Three things shift the price: whether your engine has run and for how long, how much AdBlue went in, and where the car is. That last one comes down to whether a van can get to it safely, and an open driveway is easier than a tight space behind Marks & Spencer.

Which fluid was put in, what quantity, plus if the engine ran: every Blackfell call opens with precisely that, before any figure, never afterwards. Given them, a range narrows to a single firm figure.

Our quote is given on the call, before anyone sets off; settling up happens on the day, by card or by phone, and nothing upfront. While the van is travelling, check your policy: many include misfuelling.

Beside your car around Blackfell, still?

Not touching the car is, then, the best thing you can do. Keys out, motor off, ignition off. Call 0333 366 0103: AdBlue, the amount, plus if it ran is everything our technicians need. Petrol in Diesel takes over the remainder across Tyne and Wear, Blackfell too.
