Tanshall: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in your diesel tank, your ignition remains off and so does your motor. Urea dissolved in water is all AdBlue is. Not like fuel, it neither ignites nor mixes, and nothing happens till your engine pulls it through. In Tanshall, AdBlue in a diesel tank caught before the motor runs usually means a drain and a thorough flush, right where the car is. Phone 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in your diesel tank in Tanshall

Do these:

  • Remove the keys, which stops anyone turning the power on.
  • If you're anywhere near moving traffic, put the hazard lights on.
  • The empty bottle or the till receipt tells us the fluid and the amount, and so do not bin it out.
  • Call us from where you are. A postcode starting KY6 2, or the name of the nearest street, brings our van to you without a search.

Don't:

  • Shifting your car even a short way is no reason to start your engine.
  • Do not switch the ignition on. On many diesels that alone runs the fuel pump.
  • No extra fuel added. The AdBlue will not mix, and so it's wasted.
  • Keep it where it is instead of driving it anywhere, even a short way down Forres Drive.
  • By the road, don't attempt emptying it yourself.

At a forecourt in Tanshall, whether it's the Shell or another one, ask the attendants to help you push your car away from the pump. Parked on your own driveway? Then it remains exactly where it is.

AdBlue in a diesel tank: what it does

The engine isn't what AdBlue is made for; your exhaust is. From a separate reservoir it is fed directly to your exhaust, treating what your motor lets out. Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea.

Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. It drops, because it's heavier than diesel, and settles down where the intake draws its supply from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Whitehill last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.

Once it is drawn in, the damage takes two forms. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps working on the parts it hits for as long as it remains there. Where the AdBlue is in the lines, waiting till morning in Tanshall leaves things worse. Inside that tank only, waiting costs nothing. Water lubricates nothing. The high-pressure pump and every injector need diesel running past them, and so the water content harms them in its own right.

Draining AdBlue from a diesel tank in Tanshall

Why is AdBlue in a diesel often the bigger problem?

An issue of thin fuel is what you end up with after fuelling a diesel with petrol from the another forecourt nearby. It mixes with your diesel, and whilst it's inside the tank it does no harm; the harm comes from running the motor on it.

AdBlue in a diesel is a problem of the wrong substance altogether. It can't simply be run through, because it doesn't burn. Whether the vehicle sits in Leslie or the centre of Tanshall, turning it over "to see" does more harm in this case than almost any other slip, and the flush matters for more. The reasons: it won't remain mixed, so watering it down fails; and crystals and corrosion survive the following fill.

The same good news holds as with petrol. Not run? Then the AdBlue waits only inside that tank, the easiest section of the whole system to empty, anywhere your vehicle has stopped across Fife.

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

Many vehicles put the AdBlue filler alongside the diesel one, occasionally behind a single flap, and in dim light the two may appear the same. Nobody intends it. It mostly happens at home, from a container grabbed en route home, rather than at the forecourt.

Mostly, it takes place in one of a few familiar ways. The top-up is rushed outside the local primary school, because your dash lit up with a warning while the kids were dropped off. In the evening, a container is tipped in on a driveway near Golf Course Road. Or your car is topped up in the car park outside The Prinlaws, in poor light, by someone who has never opened that flap before.

Hired vehicles, brand-new motors, fleet cars, or the second vehicle in a family with one of each: the least known cars get it the most. An identical mistake, same first response — keep it off — wherever you are in Tanshall or the remainder of Fife.

Already started your engine with AdBlue in your diesel tank around Tanshall?

Then the tank is no longer where the AdBlue is. It has been sucked through the fuel filter and the fuel lines, and if the engine ran for any time, it has got to the high-pressure fuel pump and your injectors.

Watch for lumpy running, smoke, falling power, lights on your dash, or a cut-out — returning from Glenrothes Golf Course, perhaps, or midway across Tanshall. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. Each start pulls more of it through.

If you were on the M90, under 10 miles from Tanshall, come off at the next exit and stop somewhere sensible rather than pressing on.

A quick hop across Tanshall to the car park by Play Sculpture is one matter; heading for Dunfermline, under 15 miles away, is another, since every mile pushes the AdBlue deeper in. So mileage counts. Tell us about how far it had come.

We do all of the flushing where your car has ended up, and once your engine has been started there is more of it. Very rarely does it leave long-term damage when it's spotted early.

Emptying AdBlue in a diesel in Tanshall: what it takes

A street beside St Ninians Church, a driveway, a layby or a filling station: wherever the vehicle has stopped around Tanshall, our engineers come to it. Before anything else we ask what went in, about how much, and if your engine has run, because those answers determine this work.

Next, emptying your tank right there takes out the contaminated diesel and the AdBlue in one go. With AdBlue, far more than with petrol, flushing counts: the fuel system is cleaned all the way through since residue won't flush away unaided. A test of your vehicle follows last, once clean diesel is added and your filter is flushed or, where necessary, replaced. Engine not run? Then expect roughly half an hour on site for most jobs. The pumping gear is explosion-proof, so a busy forecourt is no problem, and it is quiet enough for a residential street late at night.

Lastly, the fuel system is bled with new diesel. Firing it up comes next, and then you set off from where the car is parked, at Markinch or on a driveway in Tanshall. It's tested on new diesel to be sure it runs properly before our engineers go. Our technicians do it all wherever the car has stopped, and it never has to be taken to a garage. The insurer will want an engineer's report and the VAT invoice — both yours once this job is done.

AdBlue drains around Tanshall and across Fife

Newcastle, Macedonia and Caskieberran are among the towns around Tanshall that the same vans serve, along with most of Fife beyond, over the KY postcode area. Near a boundary, or somewhere awkward to pin down? Asking beats assuming, so phone.

Wherever the vehicle stands — a drive at home, a side street, a car park, a filling station — we drain it there, with no need to take it to us; that suits Tanshall, a residential suburb, well.

AdBlue in a diesel tank in Tanshall: the cost of fixing it

Because each callouts differ, a flat price wouldn't be honest. The cost changes first with how long, if at all, your engine has been running, and next with the amount of AdBlue that went in. After that it rests on where the vehicle is and whether a technician can reach it safely, which is easier on an open drive than in a tight gap behind Glenrothes community house.

That's why each call from Tanshall starts with the same three questions, asked before giving a figure, not after: what went in, how much, and if it's run. Once those are known, a range turns into one firm number.

Our quote is given during the call, before anyone sets off; settling up comes on the day, by card or by phone, and nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.
