AdBlue in a Diesel Tank in Water Eaton? Don't Start It

Motor off, ignition off: that is how you start if AdBlue has gone into your diesel tank. Water with urea mixed in it: that is AdBlue. It does not burn, it does not mix with diesel, and the damage it does starts when your fuel system pulls it in. In Water Eaton, AdBlue in a diesel tank caught before the engine runs normally means a drain and a thorough flush, right where the vehicle is. Call 0333 366 0103 before you do anything else.

Your next steps straight away, Water Eaton: AdBlue in your diesel tank

Do these:

  • Keys out — that way nobody can switch anything on.
  • Near moving traffic? Then put the hazards on.
  • Hold on to your receipt or the empty bottle, and so you can tell us what was put in and roughly how much.
  • Call us from where you are. A postcode starting MK2 3, or the name of the closest street, gets the van to you without a search.

Do not:

  • Do not start your engine, even for a moment to move the car.
  • Turning the key to ignition alone sets your pump going on plenty of diesels. Avoid it.
  • Pouring in extra diesel doesn't help: AdBlue separates out rather than thinning.
  • Any driving at all is to be avoided, even a short distance down Stoke Road.
  • No emptying it yourself, either, at the roadside.

Ask the people behind the counter to help you move your car away from the island if you are on a forecourt in Water Eaton, whether it's the Esso or somewhere else. At home, the vehicle stays exactly where it is.

What AdBlue does in a diesel tank

Meant for your exhaust, AdBlue has no business in the motor. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Nothing inside a fuel pump is made for this fluid — and none of that was meant to go that way.

Fuel blends; AdBlue, after tipped in, won't. The behaviour is nothing like diesel's. Denser than diesel, it sinks and pools below it — the same place the intake sucks from. When your system runs, the AdBlue is top of the list to go through. Until then it sits underneath your diesel, which is how a car filled in Bletchley last night and not started remains the simple case, as long as no one touches the key.

Two kinds of harm come from there. What remains once the water evaporates is urea, which turns into crystals: they settle in tiny passages and clog filters. On top of that, it eats at certain metals in the fuel system, and keeps going until it's cleared out. By daybreak, a car parked in Water Eaton with AdBlue in its lines grows worse; if it is just inside that tank, nothing changes. Then there's the water: it brings no lubrication to the components that need it most — the injection pump and each injector.

Draining AdBlue from a diesel tank in Water Eaton

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

Petrol put into a diesel on Shell's forecourt makes your fuel watery — that is the whole fault. Mixed through your diesel and left still, it's no threat at that stage; running the motor is the damage.

With AdBlue in a diesel, the fluid as such is simply the wrong one. Not burning, it can't just be run through. It doesn't stay mixed, so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than almost anywhere else, whether the car is in Denbigh West or the middle of Water Eaton.

The good news is the same as with petrol. If the engine hasn't run, the AdBlue is still in your tank, and that tank is the easiest part of a fuel system to clear, wherever across Buckinghamshire the car is standing.

How does AdBlue end up in a diesel tank in Water Eaton?

After dark, two caps together — the AdBlue cap and the diesel cap, now and then behind one flap — can appear the same. No one intends it; plenty of designs invite it. It mostly happens outside the house, from a bottle bought en route home, rather than at the forecourt.

The ways it occurs are few and familiar. Halfway through the morning drop-off, the dashboard flags it up, and outside Drayton Park School the refill is hurried. Someone tips the bottle in at home, right off Windermere Drive, as the day ends. Or someone new to that flap refills the car in dim light, stopped in the car park by The Turing Key.

It crops up the most in a hire car, a new car, a company vehicle, or the other motor in a family with both fuels — the vehicles people use least. Keep it switched off: that's the first response to an identical slip, wherever around Water Eaton or the rest of Buckinghamshire you happen to be.

Water Eaton: started the engine with AdBlue in the diesel tank?

The AdBlue has left the tank, then. The filter and lines have had it sucked along, and some running takes it on to the injection pump and each injector.

Perhaps returning from Waterhall Park, or midway across Water Eaton, your motor may run lumpy, smoke, drop pace, light up the dash or stall. Stop when it is safe. Turn off. Keep the vehicle off rather than testing it again. More of that is pulled through with each start.

Water Eaton lies under 5 miles from the M1; if you were on it, leave at the next junction and stop somewhere safe rather than carrying on.

A quick hop across Water Eaton to the car park by Sycamore Hall is one thing; driving towards Milton Keynes, under 5 miles away, is something else, since each mile carries the AdBlue further in. So mileage matters. Tell us about how far it had come.

Our technicians do all of the flushing where your car has stopped, and once your engine has been run there is more of it. Very rarely does it leave long-term damage if it's caught early.

What draining AdBlue from a diesel involves around Water Eaton

We come to your car, wherever it has stopped in Water Eaton: a side street close to Bletchley & Fenny Stratford Town Council, a drive, a lay-by or a forecourt. The work rests on three answers, which our technicians get first — what went in, the quantity, and whether your motor has run.

Then that tank is drained where your car waits, so the tainted fuel and the AdBlue come out together. A careful flush counts far more after AdBlue than after petrol, since what remains will not wash 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 engine has not run, the majority of jobs take about half an hour once our engineers are there. Low-noise enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.

Bleeding the system with clean diesel comes at the end. Then we start it and you drive off, whether from a parking bay at Bletchley or a driveway around Water Eaton. Before we go, our engineers check it's running properly with fresh diesel in. The entire job is done where the car is, so it never needs to go to a garage. You receive a VAT invoice and an engineer report later on, which is what insurers ask for.

AdBlue drains in Water Eaton and across Buckinghamshire

What does AdBlue in a diesel tank cost to sort out in Water Eaton?

No single price would be fair, since every job differs. The price shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that was put in. After that it turns on where your car is and whether a van can reach it safely, which is simpler on an open drive than in a tight space behind Water Eaton Church Centre.

With that reason, every enquiry from Water Eaton begins with the same trio — which fluid was put in, how much, whether the engine ran — before a figure. Those replies narrow the range down to a single figure.

Before a van sets off, you are told the quote on the phone. And payment is on the day, card or over the phone, with nothing in advance. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way.
