Don't Start It: AdBlue in a Diesel Tank in Thwaites Brow

If AdBlue has gone into the diesel tank, keep your motor off then keep the ignition off. AdBlue is urea dissolved in water. Unlike fuel, it neither burns nor mixes, and nothing starts until your engine pulls it through. A drain and a thorough flush, done where the car is around Thwaites Brow, is normally all AdBlue in a diesel tank needs — if it is caught before the engine has run. Before you do anything else, call 0333 366 0103.

Those opening minutes: AdBlue in the diesel tank in Thwaites Brow

To do:

  • So no one can switch the ignition on, pull the keys out.
  • Hazards on, if moving traffic is at all close.
  • The empty bottle or the till receipt shows us the fluid and the amount, so do not bin it away.
  • Give us a postcode starting BD21 4, or whatever street is closest, and our van reaches you directly — so call wherever you are.

Not to do:

  • Not even briefly, and not to shift the vehicle: the engine remains off.
  • Do not switch your ignition on. On many diesels that alone runs the fuel pump.
  • Do not top up with diesel to thin it. AdBlue doesn't mix in diesel; it separates out.
  • Even a short stretch up Lee Court is too far to drive the vehicle.
  • No draining it yourself, at all, on the verge.

At a forecourt around Thwaites Brow, whether it's the Sainsbury's or another one, ask the staff to help you roll your car away from the pump. Stopped on your own driveway? Then it remains just as it is.

What does AdBlue do in a diesel tank?

Not your engine but your exhaust is where AdBlue is meant to go. From a dedicated reservoir it goes directly to your exhaust, treating what your engine emits. No part inside a fuel pump is made for this liquid — and no part of it was intended to travel that way.

Fuel blends; AdBlue, once tipped in, won't. Its behaviour is nothing like diesel's. It is heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup draws fuel from. When your pump runs, the AdBlue is top of the list to be pulled through. Before then it sits beneath the diesel, which is how a vehicle filled in Strong Close last night and not started stays the simple one, as long as nobody turns the key.

Once it's sucked 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 parts it hits for as long as it remains there. Lines holding AdBlue mean harm overnight for a vehicle parked in Thwaites Brow. Only inside your tank, it stays stable. The water in it does 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 Thwaites Brow

Why AdBlue in a diesel is frequently more serious than petrol

An issue of thinned fuel is what you end up with from fuelling a diesel with petrol from the Morrisons. It mixes with the diesel, and whilst it is inside that tank it does no damage; the damage comes from running the motor on it.

AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all. Not burning, it cannot just be run through. Nor can it be thinned, because it splits back out — and the next tankful will not rinse away deposits or corrosion. So the flush counts more with AdBlue, and turning your key "to see", in the heart of Thwaites Brow or out in Worth Village, does more harm than almost any other slip.

The good news is the same as with petrol. If the engine has not run, the AdBlue is still inside the tank, and the tank is the simplest part of a fuel system to clear, wherever in West Yorkshire the car is standing.

How AdBlue ends up in a diesel tank around Thwaites Brow

No one means to do it. The AdBlue filler on plenty of motors sits right next to your diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. It mostly takes place at home, from a bottle bought on the journey home, rather than at the forecourt.

The ways it takes place are few and familiar. Hurrying, outside Long Lee Primary School, after a warning light flashed on during the school run, a parent tops up your car. In the evening, a bottle is tipped in on a drive near Calton Grove. Or the car is topped up in the car park outside Shoulder of Mutton, in poor light, by a person who has never opened that flap before.

It happens most in the motors drivers know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. An identical slip, an identical first response — leave it switched off — wherever you are in Thwaites Brow or the remainder of West Yorkshire.

Already started the motor with AdBlue in the diesel tank in Thwaites Brow?

The AdBlue has left the tank, then. Via the fuel filter, along the pipework, and — with any running time — on to the injection pump and each injector: that's how far it has gone.

Rough running, smoke, lost power, dashboard lights or stalling: each might show up, maybe part way across Thwaites Brow or coming back from Park Wood. Once safe, stop and turn it off — without turning it on again to test. More of that is pulled through with each start.

If you were on the M606, under 10 miles from Thwaites Brow, come off at the next exit and stop somewhere sensible instead of pressing on.

Each mile carries the AdBlue further into your system. That is why a hop across Thwaites Brow to park beside St Barnabas and a drive of under 10 miles for Bradford are such separate jobs. Approximately how far had it come? Tell us.

Once the engine has run, the flush takes in more, and all of it is done where the car has stopped. Very rarely does it leave long-term damage when it's spotted quickly.

What does an AdBlue drain on a diesel involve around Thwaites Brow?

Our technicians come to the vehicle, wherever it has stopped in Thwaites Brow: a side street near Long Lee Village Hall, a drive, a lay-by or a forecourt. Three replies shape the job, and so before anything else we ask which fluid went in, roughly what quantity, and whether the motor has run.

Then the tank is drained where the vehicle sits, so the tainted fuel and the AdBlue come out together. A full flush matters far more with AdBlue than after petrol, because what remains won't clear away by itself. Fresh diesel goes in once your filter is cleaned — or replaced, if it needs to be — and after that the vehicle is tested. About half an hour once we arrive is typical for most jobs where your engine has not run. Our equipment is explosion-proof, so a busy forecourt is no issue, and it is quiet enough for a residential street late at night.

Clean diesel goes in to prime the fuel system, and that is the last step. Whether it is a parking space at Keighley or a drive in Thwaites Brow, that is where our technicians start the car and you head off. Before we go, our engineers make sure it's running correctly with clean diesel in. Our engineers do it all wherever the car has ended up, and it never needs to be taken to a workshop. At the end, you are given the paperwork for your insurer: a VAT invoice and a written report from the engineer.

Thwaites Brow and West Yorkshire: AdBlue drains across the area

What does AdBlue in a diesel tank cost to sort out around Thwaites Brow?

Since each callouts differ, a single price wouldn't be honest. The price changes first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that was put in. After that it rests on where the car is and whether a van can reach it safely, which is simpler on an open driveway than in a tight space behind Keighley Bus Museum.

That's why each call from Thwaites Brow starts with the same three queries, asked before giving a figure, not after: what was put in, how much, and whether it has run. With those replies, the range narrows to one fixed number.

The price is quoted during the call, before a van sets off; settling up happens on the day, by card or by phone, with nothing upfront. While our engineer is travelling, dig out your policy: plenty cover misfuelling.
