AdBlue in a Diesel Tank in Llangewydd Court? Don't Start It

AdBlue in the diesel tank? Then leave your engine off — and the ignition as well. In plain terms, AdBlue is just urea in water. The trouble starts once it's pulled through the lines — it won't burn, and it won't blend with diesel. If your engine has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly cleaned where the car sits around Llangewydd Court. Call 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in the diesel tank around Llangewydd Court

Things to do:

  • Pull the keys out, and so nobody switches the ignition on.
  • If you are anywhere close to moving traffic, put your hazards on.
  • Hold on to the till receipt or the empty bottle, so you can tell us what was put in and about how much.
  • Call us from where you are. A postcode starting CF31 4, or the name of the closest street, gets the van to you without a search.

Things not to do:

  • No starting the engine — not briefly, not to reposition your car.
  • Switching your key to ignition alone starts your pump going on plenty of diesels. Avoid it.
  • AdBlue doesn't mix in diesel — it separates out — so adding more diesel won't thin it.
  • Even a short way up Milton Drive is too far to drive it.
  • Don't try to drain the car yourself at the kerbside.

The attendants on duty at any Llangewydd Court forecourt — the Tesco among them — will usually help pushing it aside if you ask. On your own driveway, don't move it at all.

What AdBlue does in a diesel tank

Not your engine but your exhaust is where AdBlue is meant to go. From a dedicated reservoir it goes straight to the exhaust, cleaning what your engine emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Inside a diesel tank it behaves really differently from fuel. It doesn't mix in. It is heavier than diesel, and so it sinks and gathers at the bottom of the tank, which is where the pickup pulls fuel from. Once the pump runs, the AdBlue is top of the list to go through. Before then it sits underneath your diesel, which is how a car topped up in Bryntirion yesterday and never switched on remains the simple case, provided no one touches your key.

From there it causes two kinds of damage. It attacks some metals used in fuel components, attacking any part it reaches till it is removed from your system. And once the water goes, the urea turns into crystals that clog filters and lodge in narrow passages. By daybreak, a vehicle parked around Llangewydd Court with AdBlue in its lines gets worse; if it's only inside your tank, it doesn't. The water in it causes harm of its own: the high-pressure pump and your injectors rely on diesel to lubricate them, and water gives them nothing.

Draining AdBlue from a diesel tank in Llangewydd Court

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

Petrol pumped into a diesel on Murco's forecourt makes your fuel watery — that is the main problem. No harm is done as long as it sits unused, blended into the diesel — only when your engine runs on it.

AdBlue in a diesel is a fault of the wrong substance altogether. It can't simply be run through, since it does not burn. Nor can it be thinned, because it splits again — and the next tankful will not rinse away crystals or corrosion. So the flush matters for more with AdBlue, and trying your engine "to see", in the heart of Llangewydd Court or out in Newcastle, costs more than almost any other slip.

The same good news holds as with petrol. Clearing a tank is the easiest part on a fuel system, and without running, the AdBlue remains in there — wherever across Bridgend the vehicle has stopped.

How AdBlue ends up in a diesel tank around Llangewydd Court

No one means to do it. The AdBlue filler on plenty of motors waits right next to your diesel filler, at times under the same flap, and the two caps can look alike in poor light. A container picked up while driving home and tipped in outside the house, instead of at the filling station, is the typical route.

It tends to happen in a few familiar ways. The refill gets rushed outside the local primary school, because the dash flashed with a warning while the children were dropped in. Near Keats Close, someone pours a container in at home in the evening. Or a driver unfamiliar with that flap refills your car after dark, stopped in the car park outside The West House.

The least familiar cars get it the most — hire cars, brand-new ones, fleet ones, and the spare vehicle in a home with both fuel types. Wherever around Bridgend, Llangewydd Court as well, the slip doesn't change, and neither does the first step: keep it off.

Llangewydd Court: started the motor with AdBlue in the diesel tank?

Then that tank is no longer where the AdBlue is. Given any running time, it goes on to the injection pump and each injector, after passing via the fuel filter and lines.

You may notice your engine running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Compost Cwtch or halfway across Llangewydd Court. When safe, pull over then switch everything off — with no turning it on again to test. Each start pulls more of it through.

Llangewydd Court sits under 3 miles from the M4; if you were on it, exit by the first junction and pull up safely instead of carrying on.

Every mile pushes the AdBlue further into your system. That's why a hop across Llangewydd Court to park beside Westways Community Centre and a drive of under 25 miles for Swansea are such separate jobs. About how far it had come is worth telling us.

Our engineers do all of the flushing where the car has come to a stop, and once the motor has run there is more of it. Spotted early, it very rarely leaves lasting damage.

What does an AdBlue drain on a diesel involve around Llangewydd Court?

Our technicians come to your car, wherever it has stopped in Llangewydd Court: a side street close to Y Castell Newydd, a drive, a lay-by or a forecourt. Three replies decide the job, so before anything else our engineers ask what got in, about what quantity, and if your engine has turned over.

Then that tank is emptied where your car sits, and so the contaminated fuel and the AdBlue come out together. The system is cleaned thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If your motor has not run, most jobs take about half an hour once our technicians are there. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house after dark.

The final step is to prime the fuel system on fresh diesel. Whether it is a parking space by Wildmill or a driveway in Llangewydd Court, that is where our technicians fire it up and you head off. It is tested on fresh diesel to be sure it runs properly before we go. The whole job is done where your car is, so it never has to be taken to a garage. Insurers ask for a VAT invoice and an engineer report, and you get both at the end.

What AdBlue in a diesel tank costs to put right around Llangewydd Court

No single price could be fair, since each job differs. Whether your engine has been running, and for how long, comes first in what changes the price. How much AdBlue was put in comes next, and then the location of your car, since an open drive is simpler for a technician to get to safely than a tight gap behind St Illtyds Church.

Which fluid was put in, how much, and if it ran: each Llangewydd Court call begins by asking exactly that, ahead of any quote, never afterwards. Once those are known, a range turns into one firm number.

The price is quoted during the call, before a van sets off; settling up happens on the day, by card or by phone, and nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.
