AdBlue in the Diesel Tank in Finchley? Keep It Switched Off

Motor off, ignition off: that is how you start if AdBlue has got into your diesel tank. AdBlue is urea mixed in water. The harm starts once it is sucked through your lines — it will not burn, and it will not combine with diesel. A drain and a thorough flush, done where your car is in Finchley, is usually what AdBlue in a diesel tank takes — if it is caught before the motor has run. Before you do anything else, phone 0333 366 0103.

What to do straight away, Finchley: AdBlue in your diesel tank

Do:

  • Pull your keys out, so no one switches your ignition on.
  • Put your hazards on if you're anywhere close to moving traffic.
  • The empty bottle or the till receipt shows us the product and the amount, and so do not bin it out.
  • The van finds you fastest with a postcode starting N3 2, or simply the name of a street nearby, so phone from the spot.

Not to do:

  • Not even for a second, and not to shift the car: the engine stays off.
  • Your ignition stays off: on many diesels, switching it on is enough to run the pump.
  • No extra fuel added. The AdBlue won't mix, and so it is wasted.
  • Do not drive it anywhere, not even a short stretch up Hendon Lane.
  • By the road, do not attempt draining it on your own.

On a forecourt in Finchley, whether it's the BP or another one, ask the attendants to help you roll the vehicle away from the pump. At your own drive, do not touch it at all.

AdBlue in a diesel tank: what it does

AdBlue is made for the exhaust, not the motor. Kept in a separate tank, it's injected into the exhaust to clean the fumes. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It's heavier than diesel, so it sinks and collects at the bottom of the tank, which is where the pickup draws fuel from. The first thing the system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Temple Fortune last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in.

Two kinds of harm follow from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filters and narrow channels; and, because it attacks certain metals, each part it touches suffers for as long as it remains inside. A car left sitting around Finchley with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Diesel lubricates the injection pump and each injector as it flows; water gives none of that, which is a second kind of damage.

Draining AdBlue from a diesel tank in Finchley

Why AdBlue in a diesel is commonly more significant than petrol

A problem of thin fuel is what you end up with from fuelling a diesel with petrol from the Esso. Damage just comes from driving on it. Blended into the diesel and sitting in the tank, it causes nothing.

AdBlue in a diesel is an issue of the wrong substance altogether. Not burning, it can't simply be run through. It doesn't stay mixed, so it cannot be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether your car is in Golders Green or the middle of Finchley.

With AdBlue, the good news is no different from petrol. Not run? Then the AdBlue sits just in that tank, the simplest bit of the whole system to clear, anywhere the vehicle has stopped across Greater London.

Finchley: how AdBlue ends up in a diesel tank

It's not deliberate. Many cars have the AdBlue cap alongside the diesel one, occasionally behind a single flap, and mixing them up is simple after dark. It usually occurs outside the house, from a container grabbed en route home, not at the filling station.

It tends to happen in a couple of familiar ways. A warning light comes on during the school run, and the top-up takes place in a hurry outside Pardes House Primary School. A driver pours the container in at home, right off Lichfield Grove, as the day ends. Or someone new to that flap tops up your car after dark, stopped in the car park by King of Prussia.

It occurs most in the vehicles drivers know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Leave it switched off: that is the first step to an identical slip, anywhere around Finchley or the remainder of Greater London you are.

Finchley: started the engine with AdBlue in the diesel tank?

Then the tank is no longer where the AdBlue is. Through the fuel filter, through the lines, and — with any running time — into the high-pressure pump and every injector: that's how far it has gone.

Expect lumpy running, exhaust smoke, lost power, lights on your dash, or a cut-out — returning from Church End Gardens, perhaps, or midway across Finchley. Stop when it is safe. Switch off. Leave the vehicle off instead of restarting it to check. Each start pulls more of that through.

Exit the M1, under 3 miles from Finchley, by the next junction and stop safely, rather than driving on.

Every mile carries the AdBlue further in. That is why crossing Finchley to park near St Mary's Court and a drive of under 10 miles towards London are very different jobs. Roughly how far it had come is worth telling us.

Our engineers do all of the flushing where the car has come to a stop, and once the motor has been run there is more of it. Spotted quickly, it very seldom leaves permanent damage.

What draining AdBlue from a diesel involves in Finchley

Anywhere it has come to rest around Finchley — a forecourt, a lay-by, a drive, a road by Barnet County Court — our van comes to the car. What was put in, roughly how much, and if your motor has turned over: we ask first, since those decide the job.

Then that tank is emptied where the car waits, and so the tainted fuel and the AdBlue come out together. A careful flush counts far more after AdBlue than with petrol, because what remains won't wash out by itself. After that, your filter: flushed, or changed if it must be. Then fresh diesel, then a test of the vehicle. If your motor hasn't run, the majority of jobs take about half an hour once our technicians arrive. Low-noise enough to use outside a house at night, and fine on a busy forecourt, our pumps are explosion-proof.

New diesel goes in to prime your system, and that is the last step. Starting the engine comes next, and then you head off from where your car is parked, at Hendon or on a driveway in Finchley. Before we leave, our engineers check it is running correctly with fresh diesel in. No workshop is required at any stage, with the whole job done on the spot. Your insurer will want an engineer's report and the VAT invoice — both yours once the job is done.

About Finchley and where it is

Finchley is a locality in the London Borough of Barnet, situated near the River Brent and approximately 7 miles from central London. Finchley sits at an elevation of around 93 metres, with its residential areas comprising a mix of housing types, although flats are predominant. Finchley is close to other nearby places, including Church End, Holders Hill, and North Finchley, and is part of the wider north London urban landscape. Finchley has a population of around 5585 people, according to recent estimates.

AdBlue drains across Finchley and Greater London

AdBlue jobs in Finchley go to teams that serve the places near it — Church End, Holders Hill as well as North Finchley — and much of Greater London further out, throughout N postcodes. If you are near a border, or somewhere hard to describe, ring and ask rather than assuming.

A van that comes to you suits Finchley, a small village: there's no need to bring your vehicle to us, because our technicians drain it there, in a drive, a residential street, a parking area or a forecourt.

Finchley: what AdBlue in a diesel tank costs to fix

No single price could be fair, since every job differs. What shifts the cost is, first, whether your engine has been running and for how long; then how much AdBlue went in; and finally where your car is and whether a van can get to it safely, which is simpler on an open driveway than in a tight spot behind Church End Library.

For that in mind, every enquiry from Finchley opens by asking the same trio — which fluid went in, how much, if it ran — ahead of a quote. With them, the range shrinks to one fixed figure.

You get that price by phone, before anybody sets off, and you pay on the day, by card or by phone, with nothing upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
