Middleton-in-Teesdale: AdBlue in the Diesel Tank? Leave It Off

AdBlue in the diesel tank? Then leave the motor off — and the ignition too. Water with urea mixed in it: that is AdBlue. As it is water-based, it won't burn and never combines with diesel; trouble just comes when your pump starts pulling it. In Middleton-in-Teesdale, AdBlue in a diesel tank found before the motor runs normally means a drain and a thorough flush, just where your car is. No step comes before ringing 0333 366 0103.

AdBlue in the diesel tank in Middleton-in-Teesdale: the first few minutes

Do these:

  • Take your keys out, and so nobody switches the ignition on.
  • Hazards on, if moving traffic is at all close.
  • Hold on to the receipt or the empty bottle, so you can tell us what was put in and about how much.
  • The van locates you fastest with a postcode starting DL12 0, or just the name of a street nearby, and so phone from the spot.

Things not to do:

  • Do not start your engine, even for a moment to shift the car.
  • Many diesels power their fuel pump the instant your ignition goes on, so leave the car off.
  • AdBlue does not mix in diesel — it separates out — so adding more fuel will not weaken it.
  • Never drive it anywhere, not even a short distance up Horsemarket.
  • Draining that tank on your own beside the road isn't one to try.

The staff working at any Middleton-in-Teesdale filling station — the Alston Road Garage included — will usually lend a hand pushing it aside if you ask. At your own drive, don't touch it at all.

AdBlue in a diesel tank, and what it does there

AdBlue is made for the exhaust, not your motor. From a separate reservoir it goes straight to your exhaust, cleaning what your motor emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Fuel mixes; AdBlue, after tipped in, will not. Its behaviour is not at all like fuel's. It drops, since it is heavier than diesel, and pools down where the intake draws its fuel from. When your pump runs, the AdBlue is first to be pulled through. Until then it sits underneath your diesel, which is how a car topped up in High Dyke last night and never switched on remains the simple one, provided no one touches your key.

Once it's drawn in, the damage takes two forms. It eats at some metals found in fuel systems, attacking whatever it touches till it's cleared from your system. And once the water goes, the urea forms crystals that block filters and lodge in narrow passages. If the AdBlue is in the pipework, waiting overnight around Middleton-in-Teesdale leaves it worse. Inside the tank only, time does nothing. Diesel protects the injection pump and every injector as it flows; water gives no lubrication, which is a separate form of damage.

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

Petrol put into a diesel on Northern Energy's forecourt makes your fuel watery — that's the main issue. Mixed into the diesel and left still, it's no threat at that stage; using the engine does the damage.

The trouble with AdBlue in a diesel is a totally wrong liquid. It can't just be run through, since it doesn't burn. It doesn't stay mixed, and so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether the car is in Lane Side or the middle of Middleton-in-Teesdale.

As with petrol, there is good news. Never started? Then the AdBlue waits just in that tank, the simplest bit of the whole system to clear, wherever your vehicle has stopped in Durham.

How AdBlue ends up in a diesel tank around Middleton-in-Teesdale

After dark, two caps together — the AdBlue cap and the diesel one, occasionally behind a single flap — can appear the same. Nobody means it; many designs invite it. A bottle picked up while heading home and tipped in at home, instead of at the filling station, is the typical route.

The ways it occurs are few and familiar. Midway through the drop-off, the dashboard warns, and outside Middleton-In-Teesdale Academy the refill is rushed. After work, a container is tipped in on a driveway close to Bridge Street. One more version: darkness, the car park outside The Forresters, and someone using that flap the first time.

Hired motors, brand-new motors, company motors, or the second vehicle in a home with both fuels: the least familiar vehicles see it the most. Keep it switched off: that's the first response to an identical slip, wherever in Middleton-in-Teesdale or the remainder of Durham you happen to be.

AdBlue in your diesel tank around Middleton-in-Teesdale, and the motor started?

In that case, the AdBlue is no longer in your tank. It's been sucked through your filter and your lines, and if your engine ran for any time, it has reached your high-pressure pump and the fuel injectors.

Rough running, smoke, lost power, dashboard lights or cutting out: each might show up, perhaps midway across Middleton-in-Teesdale or returning from Middleton Quarry SSSI. When safe, pull over and turn it off — with no turning it on again to test. Every start pulls more of it through.

Leave the A1(M), under 25 miles from Middleton-in-Teesdale, by the first junction and park somewhere safe, not carrying on.

Hopping across Middleton-in-Teesdale to the car park by Middleton-in-Teesdale War Memorial is one thing; heading towards Durham, under 25 miles away, is another, since each mile pushes the AdBlue deeper in. So distance matters. Roughly how far had it come? Tell us.

Wherever the car came to a stop is where all of it gets done, even with more to clean out after your engine has been started. When it's noticed quickly, lasting damage is very unusual.

What does an AdBlue drain on a diesel involve around Middleton-in-Teesdale?

Our technicians come to the vehicle, wherever it has stopped in Middleton-in-Teesdale: a side street close to Fitzhugh Library, a drive, a lay-by or a forecourt. The job rests on three answers, which we get first — what went in, the amount, and whether the engine has turned over.

The contaminated diesel and the urea leave as one after your tank is drained, right there. What remains from AdBlue won't wash out unaided, and so the fuel system gets a careful flush, which matters much more with urea than with petrol. Fresh diesel goes in after your filter is flushed — or replaced, if it needs to be — and after that your car is tested. Most of these jobs are a half-hour job once we get there, if your motor hasn't run. Explosion-proof pumps mean a live forecourt sensible to work on, and they're quiet enough to spare the street at night.

The last step is to bleed the fuel system on new diesel. Starting the car comes next, and then you drive off from where the vehicle is parked, at the nearest station or on a driveway in Middleton-in-Teesdale. The test before our engineers go is that it runs smoothly on clean diesel. Because the job is done in its entirety where the vehicle is, a garage never comes into it. At the end, there is paperwork for the insurer: a VAT invoice and a written report from the engineer.

Middleton-in-Teesdale: what AdBlue in a diesel tank costs to fix

Because each callouts vary, a flat figure would not be fair. What shifts the price is, first, whether the motor has been running and for how long; then how much AdBlue got in; and after that where the car is and whether a van can reach it safely, which is easier on an open drive than in a tight space behind Window tracery.

What got in, how much, and whether the engine ran: every Middleton-in-Teesdale call opens with precisely that, before any quote, never afterwards. Given them, the range narrows to a single fixed figure.
