Lower Brora: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in your diesel tank, your ignition stays off and so does your engine. AdBlue is urea mixed in water. Being water-based, it will not ignite and won't blend with diesel; trouble just starts when your pump starts pulling it. If your engine has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly flushed where the vehicle sits in Lower Brora. Before anything, phone us on 0333 366 0103.

What to do straight away, Lower Brora: AdBlue in the diesel tank

Do these:

  • Pull your keys out, so no one switches your ignition on.
  • If you're anywhere near moving traffic, put your hazards on.
  • So you can tell us which fluid it was and about what quantity, save the till receipt or the empty bottle.
  • Give us a postcode starting KW9 6, or whichever street lies closest, and our van finds you straight — so ring from wherever you stand.

Not to do:

  • Not even for a second, and not to roll your car: the motor remains off.
  • Plenty of diesels run their fuel pump the moment your ignition goes on, so keep the car off.
  • No extra fuel added. The AdBlue will not mix, so it is wasted.
  • Never drive the vehicle anywhere, not even a short way down Johnstone Place.
  • Draining that tank on your own by the road is not worth trying.

The staff working at any Lower Brora forecourt — the Gleaner among them — will normally lend a hand pushing it clear if you ask. Parked on your own drive? Then it stays exactly as it is.

What does AdBlue do in a diesel tank?

Meant for your exhaust, AdBlue has no place in your motor. From a separate tank it goes directly to your exhaust, cleaning what your engine emits. A fuel pump is not designed to cope with it, and AdBlue was never intended to go through one.

Inside a diesel tank it behaves very differently from fuel. It does not mix in. It sinks, because it is denser than diesel, and pools low where the pickup draws its fuel from. Simplest of all: one that got AdBlue in Ardachew overnight and hasn't been started since. The liquid sits at the foot of that tank, undrawn — though it would be first through if the engine starts, before any diesel at all.

Once it's drawn in, the damage takes two forms. It attacks certain metals found in fuel systems, working on any part it reaches till it's removed from your system. And once the water goes, the urea turns into crystals that block filters and settle in tiny channels. By daybreak, a car sitting around Lower Brora with AdBlue through its pipework gets worse; if it's just in the tank, nothing changes. Then there is the water: it brings no protection to the parts that rely on it the most — the high-pressure pump and each injector.

Draining AdBlue from a diesel tank in Lower Brora

AdBlue in a diesel: why it's frequently worse than petrol

A problem of thinned fuel is what you end up with from fuelling a diesel with petrol from the Gulf. No damage comes as long as it stays unused, blended into the diesel — only when the engine runs on it.

With AdBlue in a diesel, the liquid as such is simply the wrong one. Not burning, it can't simply be run through. Nor can it be watered down, because it separates again — and the following fill won't clear away deposits or corrosion. So the flush matters for more with AdBlue, and trying the engine "to see", in the heart of Lower Brora or out in Bruachrobie, does more harm than nearly any other mistake.

As with petrol, there is good news. If your engine has not run, the AdBlue is still inside your tank, and your tank is the easiest part of a fuel system to clear, wherever across Highland the vehicle is standing.

AdBlue in a diesel tank in Lower Brora: how it ends up there

No one means to do it. The AdBlue filler on many cars rests right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Mostly it is never the filling station: a driver buys a container heading home and pours it in at home.

A few familiar ways account for most cases. A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school. Close to Carrol Crescent, a driver tips a bottle in on that drive after work. One more version: darkness, the car park outside the pub in the village, and someone opening that flap for the first time.

Rented cars, new cars, fleet motors, or the second vehicle in a home with one of each: the least familiar cars get it the most. Anywhere around Highland, Lower Brora as well, the mistake doesn't change, and neither does the first step: keep it off.

AdBlue in your diesel tank around Lower Brora, and your engine started?

If so, the AdBlue is no longer inside that tank. The fuel filter and pipework have had it sucked along, and some running takes it on to the high-pressure pump and every injector.

You may see your motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Brora Golf Club or halfway across Lower Brora. Stop as soon as it is safe, switch off, and do not restart the vehicle to check. With each start, more of it is pulled through.

On the M90, over 50 miles from Lower Brora, the first junction is where to exit, and anywhere safe is where to stop — not driving on.

A quick hop across Lower Brora to the car park by Brora Library is one matter; heading for Inverness, under 50 miles away, is something else, because every mile pushes the AdBlue further in. So distance matters. Approximately how far had it come? Tell us.

There's more to rinse out once the motor has been started, and our engineers do all of it where the vehicle has ended up. Spotted quickly, it very seldom leaves long-term damage.

Emptying AdBlue in a diesel in Lower Brora: what it takes

Our engineers come to your car, wherever it has stopped in Lower Brora: a side street near Brora Community Centre, a drive, a lay-by or a forecourt. Three answers shape the job, so first our technicians ask which fluid went in, roughly the amount, plus whether your engine has turned over.

On the spot, your tank is then emptied, and all of the contaminated diesel and the urea come out at once. With AdBlue, far more than with petrol, the flush counts: the fuel system is cleaned right through since residue will not flush away unaided. Fresh diesel goes in once the fuel filter is cleaned — or replaced, when it needs to be — and after that the vehicle is tested. Engine not run? In that case count on about half an hour once we are there for most jobs. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house at night.

Priming the fuel system with clean diesel comes at the end. Whether it's a parking space at Brora or a drive in Lower Brora, that is where we fire it up and you head off. Before we leave, our technicians confirm it is running correctly with fresh diesel in. The entire job is done where the car is, so it never has to go to a workshop. Insurers want a VAT invoice and an engineer report, and both come afterwards.

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

Since each jobs differ, a flat figure would not be honest. What shifts the cost is, firstly, whether the motor has run and for how long; then how much AdBlue went in; and then where the car is and whether a van can get to it safely, which is simpler on an open drive than in a tight space behind Jubilee Fountain.

Which fluid was put in, how much, and whether it ran: each Lower Brora enquiry begins with precisely that, ahead of a figure, not after. Those replies turn a range into a straight quote.

You get that quote by phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront. Check your policy whilst we are on the way: many carry misfuelling cover.
