Preventing AdBlue in a Diesel Tank in Langley: Why It Happens
Stop reading for a moment when your diesel tank already has AdBlue in it: ignition off, motor off, then phone 0333 366 0103. Caught before the engine runs, it's usually a drain and a thorough flush, done where the car is around Langley. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it does not.
AdBlue in a diesel car: two tanks, two fillers
Many modern diesels around Lime Field, like those in Langley, carry on two fluids; your engine gets just your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Different tanks, different fillers. Some cars keep the AdBlue filler in your boot or under the bonnet; a lot more have both side by side under one flap. The diesel side is filled at the pump all the time. Seldom filled, AdBlue usually comes from a bottle, poured by someone who has to stop and think what filler to use. That gap is where the error lives.
Langley: how AdBlue in your diesel tank happens
Carelessness rarely explains it. What does is three things coming up together.
On a driveway off Newton Crescent before work, or in the car park at The White Hart heading home: that's where the rushed top-up happens. Why the rush? As AdBlue gets low your car tells you, and if it's gone, limp mode follows.
Then, your hand goes for the cap it knew on the old motor — since a rental car, a new motor or a company car places the fillers where your last one didn't.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip once it has started. The same few seconds decide it, in the middle of Langley or out in Birch.
The AdBlue filler and the diesel filler: telling them apart
Be it a Langley forecourt or a driveway over in Rhodes Green, spend a couple of seconds over these before anything goes in.
- Check the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually are not.
- Check the size: the smaller neck is, on many motors, the AdBlue one.
- Check inside your fuel flap: plenty of cars carry a label there saying which fuel goes where.
- In the boot or under the bonnet: that's where the filler sits if it's not by your diesel cap, and the handbook tells you which.
- Picking up a hire or company car, say at the car park outside Mills Hill? Check with whoever drove the vehicle last before leaving, rather than when the light goes on.
How to top up without AdBlue in your diesel tank
Wherever in Greater Manchester the light comes on, this is a routine for the day.
- Stop on level, engine off, with time to spare — never rushing on the side of Martindale Crescent.
- Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap works — after you've located the filler and read the cap.
- Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Stop when the tank is topped up or the bottle is empty; until then, pour slowly using the own spout.
- Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened.
Spot at stage two or three that it has already gone into the diesel side? Then stop right there. Skip stage five altogether.
AdBlue in your diesel tank already, in Langley?
Do not start the engine: that's how the short order of things starts. Leave the ignition off too, since on many diesels it by itself starts your pump. Topping up with diesel will not weaken it: rather than mixing, AdBlue drops to the bottom of that tank, right where the fuel is taken from.
If you are at a forecourt, whether it is the BP or the Tesco, ask the staff to help roll the vehicle clear of the petrol pump. Your own drive around Langley is the place it stays.
Stop as soon as it is safe and switch off, if the engine has already run. Leave the M62 — under a mile out of Langley — at the first junction. A short hop across Langley is a smaller job than a run towards Manchester, under 10 miles away, so tell us about how far it went.
Langley: what happens when we get there
Our technicians come to the vehicle wherever it has stopped, whether that is outside Bowlee Park Community Primary School, close to The Redeemed Christian Church of God or on your own drive. Those replies determine the work and our price, and so our engineers ask what got in, roughly how much, and whether it has run. During the phone call itself, you hear our quote — ahead of dispatch.
The system is then purged thoroughly, once that tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why the flush matters more here than with petrol. A test is last: before that, fresh diesel is added, and your filter is flushed or changed as needed. Before leaving, our technicians start the car and check that it is running smoothly.
If your engine hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your insurance while we travel to you: misfuelling cover is included with plenty of policies.
