AdBlue in a Diesel Tank in Paston? Don't Start It

AdBlue in the diesel tank? Then leave your motor off — and your ignition too. Urea dissolved in water is what AdBlue is. Unlike fuel, it neither burns nor mixes, and no harm starts until the engine pulls it through. Caught before your motor has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the vehicle is in Paston. Ring 0333 366 0103 before you do anything else.

AdBlue in your diesel tank around Paston: the first few minutes

Do these:

  • Keys out — that way nobody can power anything on.
  • If you are anywhere close to moving traffic, put your hazards on.
  • The empty bottle or your receipt shows us the fluid and the quantity, and so do not throw it out.
  • Call us from where you are. A postcode starting PE4 7, or the name of the closest street, brings our van to you without a search.

Don't do these:

  • No starting your motor — not for a second, not to reposition the car.
  • Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.
  • AdBlue does not dilute in diesel — it separates out — so adding more diesel will not thin it.
  • Do not drive the vehicle anywhere, not even a short way along Topmoor Way.
  • No draining it yourself, at all, on the roadside.

At a forecourt in Paston, whether it's the Esso or another one, ask the staff to help you roll the car away from the pump. Stopped on your own driveway? Then it stays just where it is.

AdBlue in a diesel tank: what it does

Not your motor but your exhaust is where AdBlue is meant to go. From a separate reservoir it is fed directly to your exhaust, treating what the motor emits. A fuel pump isn't made to cope with it, and AdBlue was never supposed to go through one.

Tipped in with the diesel, it stays separate instead of mixing — quite unlike fuel. Heavier than diesel, it drops and collects below it — the same place the intake draws from. The first thing the system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Walton last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.

After it is sucked in, the damage comes in two forms. Crystals and corrosion. As the water dries, it leaves urea that hardens in filters and narrow passages; and, since it attacks certain metals, every part it touches suffers for as long as it remains inside. By daybreak, a vehicle sitting in Paston with AdBlue in its lines grows worse; if it is only in your tank, nothing changes. The water in it causes damage of its own: your high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water gives them nothing.

AdBlue in a diesel: why it is often worse than petrol

Top up a diesel with petrol by mistake at the Morrisons, and the problem is thinned fuel. Harm only comes from running on it. Mixed into the diesel and sitting in that tank, it causes nothing.

AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all. Since it does not burn, running it through is not an option. Crystals and corrosion stay through the next tankful, and AdBlue splits again out of the diesel, and so watering it won't work. Hence the flush counts so much, and trying your engine "to see" does more harm with AdBlue than almost any other slip — in Millfield or the centre of Paston equally.

With AdBlue, the good news is no separate from petrol. If your motor has not run, the AdBlue is still inside that tank, and that tank is the quickest part of a fuel system to clear, wherever in Cambridgeshire your car is standing.

How does AdBlue end up in a diesel tank in Paston?

After dark, two caps side by side — the AdBlue one and the diesel one, occasionally under one flap — can look the same. No one means it; many designs allow it. It usually happens outside the house, from a bottle bought on the journey home, rather than at the filling station.

A couple of familiar ways account for the majority of them. A warning light comes on during the school run, and the top-up happens in a hurry outside Paston Ridings Primary School. Close to A47, someone tips a bottle in on that drive in the evening. Or someone unfamiliar with that flap tops up the vehicle in dim light, parked in the car park outside Blue Bell.

It crops up the most in a hire car, a brand-new motor, a fleet vehicle, or the other motor of a home with one of each fuels — the vehicles people use least. Keep it switched off: that is the first step to the same mistake, wherever in Paston or the remainder of Cambridgeshire you are.

Already started the motor with AdBlue in the diesel tank around Paston?

Then your tank is no longer where the AdBlue is. Given any running, it travels to the high-pressure pump and every injector, after passing through the fuel filter and pipework.

You may notice the engine running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Itter Park or halfway across Paston. Stop as soon as it is safe, switch off, and do not restart the vehicle to check. More of that is pulled through with each start.

Paston sits under 10 miles from the A1(M); if you were on it, exit at the first junction and stop safely instead of driving on.

A quick hop across Paston to the car park by All Saints Paston Church is one matter; driving towards Peterborough, under 3 miles away, is something else, since each mile pushes the AdBlue further in. So distance counts. Tell us about how far it had come.

There is more to flush once the engine has been run, and our engineers do all of it where the vehicle has stopped. Noticed quickly, it very seldom leaves permanent damage.

Draining AdBlue in a diesel in Paston: what it takes

Anywhere it has come to rest around Paston — a filling station, a lay-by, a drive, a street beside Loveworld Church — the van comes to the vehicle. The job depends on three answers, and we ask for before all else — which fluid was put in, the quantity, and whether the engine has run.

Then the tank is drained where the vehicle waits, and so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the whole system is cleaned all the way through because what remains will not wash away by itself. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Roughly half an hour once we arrive is usual for most jobs when your motor has not run. Our equipment is explosion-proof, so a live forecourt is no problem, and it's hushed enough for a residential street late at night.

Priming the system with fresh diesel comes at the end. After that our technicians start the engine and you drive off, whether from a parking space outside Peterborough or a drive around Paston. Before leaving, our technicians check it's running properly with clean diesel in. We do it all wherever your car has ended up, and it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come at the end.

Paston and Cambridgeshire: AdBlue drains across the area

Over the PE postcode area, the vans answering AdBlue jobs in Paston reach much of Cambridgeshire as well, Gunthorpe, New England and Dogsthorpe included. If you're close to a boundary, or somewhere hard to describe, ring and ask rather than guessing.

A mobile service suits Paston, a residential suburb: you have no need to bring the vehicle to us, because our technicians empty it there, on a drive, a side street, a car park or a forecourt.

AdBlue in a diesel tank around Paston: the cost of fixing it

Every job is different, and so no fixed price would be fair. Whether the motor has run, and for how long, comes first in what changes the price. How much AdBlue got in comes next, and then the position of the vehicle, since an open drive is simpler for our van to reach safely than a tight gap behind open door center.

With that reason, each enquiry from Paston opens with the same trio — what went in, what quantity, if the engine ran — ahead of a quote. With them, a range narrows to one fixed figure.

The quote is given during the call, before anyone sets off; settling up comes on the day, by card or over the phone, with nothing upfront. While our engineer is travelling, dig out your policy: many include misfuelling.

Still beside the car in Paston?
