AdBlue in the Diesel Tank in Aberystwyth? Keep It Switched Off
Motor off, ignition off: that's where you start if AdBlue has gone into the diesel tank. Water with urea mixed in it: that is AdBlue. Unlike fuel, it neither burns nor mixes, and nothing starts till your engine pulls it round. If your engine hasn't run yet, AdBlue in a diesel tank is usually emptied and thoroughly cleaned where your car sits around Aberystwyth. Before you do anything else, ring 0333 366 0103.
AdBlue in the diesel tank in Aberystwyth: the first few minutes
Things to do:
- Pull the keys out, so nobody switches the ignition on.
- Hazards on, if moving traffic is at all close.
- So you can tell us which liquid it was and roughly what quantity, save the receipt or the empty bottle.
- Call just where you are. Say a SY23 1 postcode or the closest street sign, and nobody has to search for you.
Never:
- Do not start the engine, even for a moment to move the vehicle.
- Do not switch your ignition on. On many diesels that alone runs the fuel pump.
- AdBlue doesn't dilute in diesel — it separates out — so adding extra fuel won't thin it.
- Never drive the car anywhere, not even a short way along Great Darkgate Street.
- No draining it yourself, at all, on the roadside.
Get the attendants to help you move the vehicle off the pumps if you are at a forecourt around Aberystwyth, whether it's the Texaco or somewhere else. On that drive, the car stays just where it was left.
AdBlue in a diesel tank, and what it does there
Made for your exhaust, AdBlue has no place in your motor. Its own reservoir keeps it, and from there it's fed into the exhaust, where it treats the fumes. Neither side suits the other: urea doesn't belong in a pump, and an injection pump can't take urea.
It does not combine. After it's tipped into the tank, AdBlue behaves not at all like fuel. The intake sucks fuel from the lowest part of your tank, and that is just where AdBlue ends up: being heavier than diesel, it sinks. A vehicle filled on a drive in Caeffynnon overnight and not started since counts as the straightforward one. No pump has sucked the AdBlue up so far — though when the engine turns, that is what goes first, straight from the bottom of your tank.
It causes two kinds of harm from there. 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, and so it keeps running on the parts it reaches for as long as it stays there. By daybreak, a vehicle parked in Aberystwyth with AdBlue in its lines gets worse; if it's just inside the tank, nothing changes. Diesel protects the injection pump and every injector as it flows; water gives no lubrication, and that is a second form of harm.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Fill a diesel with petrol in error at the Morrisons, and the issue is diluted fuel. Blended into the diesel and left unused, it is no threat for now; using the engine does the harm.
AdBlue in a diesel is a fault of the wrong substance altogether. It does not burn, and so it cannot just be run through. Crystals and corrosion remain through the next fill, and AdBlue separates back from your diesel, and so thinning it won't work. Hence the flush matters more, and trying your engine "to see" costs more with AdBlue than nearly any other mistake — in Penparcau or the heart of Aberystwyth equally.
The same good news applies as with petrol. Not run? Then the AdBlue sits only in the tank, the easiest section of the entire system to empty, wherever your vehicle has come to rest across Ceredigion.
How AdBlue ends up in a diesel tank in Aberystwyth
Nobody means to do it. The AdBlue filler on many vehicles rests right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. Most of the time it takes place with a bottle bought on the way home and poured in on the drive, not at the forecourt.
A few familiar ways account for most cases. Midway through the drop-off, the dashboard warns, and outside the local primary school the top-up is hurried. Close to Chalybeate Street, someone tips a container in on the drive in the evening. Or the vehicle is topped up in the car park at Bottle and Barrel, in poor light, by a person who has never opened that flap before.
Rented vehicles, new motors, fleet vehicles, or the spare car in a family with one of each: the least known vehicles get it most. Anywhere in Ceredigion, Aberystwyth as well, the slip doesn't change, and nor does the first step: keep it switched off.
Already started the motor with AdBlue in the diesel tank in Aberystwyth?
Then the tank is no longer where the AdBlue is. Your filter and lines have had it pulled along, and any running time carries it on to the high-pressure pump and each injector.
Expect rough running, exhaust smoke, lost power, warnings on the dash, or a cut-out — returning from Castle Grounds, perhaps, or midway across Aberystwyth. No starting it again to check: stop once it is safe, then turn everything off. More of it is pulled through with each start.
Aberystwyth lies under 50 miles from the M4; if you were on it, exit by the next junction and stop somewhere safe rather than driving on.
Distance counts: each mile carries the AdBlue deeper in, so heading towards Swansea, over 50 miles away, makes a far larger job than hopping across Aberystwyth to the car park by Seion. Roughly how far it had come is worth telling us.
Wherever the vehicle came to a halt is where all of it gets done, even with more to rinse out after the motor has been run. Long-term damage is very rare when it is caught soon.
Aberystwyth: how AdBlue is drained from a diesel
Anywhere it has stopped in Aberystwyth — a forecourt, a layby, a drive, a road beside Aberystwyth Town Council — our van travels to the car. The work rests on three answers, and we ask for before all else — which fluid went in, the quantity, and whether your motor has run.
Next, emptying that tank on the spot removes the contaminated diesel and the AdBlue in one go. A full flush counts much more after AdBlue than after petrol, because residue will not wash away by itself. After that, your filter: cleaned, or replaced when it must be. After that clean diesel, and then a test of the car. Not run? In that case count on about half an hour on site for most jobs. Low-noise enough to use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.
The final step is to bleed the fuel system on new diesel. Whether it is a parking space outside the nearest station or a driveway around Aberystwyth, that is where our engineers fire it up and you drive off. The test before we go is that it runs smoothly on new diesel. Since the job is done in its entirety where the car is, a garage never comes into it. At the end, you are given the paperwork for your insurer: a VAT invoice plus a report from the engineer.
About Aberystwyth
Aberystwyth is a significant coastal town in Wales, situated in the county of Ceredigion. It is notable for being home to a major university and boasts a seaside location. The town is also the largest settlement in its county, with nearby Aberaeron also holding administrative importance. Aberystwyth's blend of education and coastal charm makes it a unique place.
Aberystwyth and Ceredigion: AdBlue drains across the area
The vans that answer AdBlue call-outs in Aberystwyth also cover the places around it, Buarth Mawr, Trefechan and Penglais among them, and most of Ceredigion beyond, across the SY postcode area. If you're close to a border, or somewhere hard to explain, ring and ask instead of assuming.
No moving is needed. In Aberystwyth, a coastal town, a mobile service works: your vehicle is drained on the spot, whether in a drive, a side street, a parking area or a forecourt.
What does AdBlue in a diesel tank cost to sort out in Aberystwyth?
No flat figure could be fair, because each job differs. The cost changes first with how long, if at all, the motor has been running, and next with the amount of AdBlue that was put in. After that it turns on where the car is and whether a van can get to it safely, which is easier on an open drive than in a tight gap behind Bethel.
Before any figure, never afterwards, each call from Aberystwyth opens with three checks: the liquid, the amount, and if it ran. When those are known, a range turns into one firm number.
Quoted on the call before the engineer heads out, the job is settled that day — card or phone, nothing in advance. While our engineer is travelling, dig out your insurance: many cover misfuelling.
Beside the vehicle in Aberystwyth, right now?
Then the most useful thing you can do is nothing to the vehicle. Keys out, motor off, ignition off. Tell us it's AdBlue, roughly how big an amount, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, across Aberystwyth or wherever in Ceredigion.
