Ddol: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that is how you begin if AdBlue has gone into your diesel tank. AdBlue is urea dissolved in water. The harm begins once it is sucked through your pump — it won't burn, and it won't combine with diesel. A drain and a thorough flush, done where the car is in Ddol, is usually all AdBlue in a diesel tank needs — if it's caught before the motor has been run. No step comes before ringing 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank around Ddol
Things to do:
- Take your keys out, and so nobody switches the ignition on.
- Put the hazard lights on if you are at all close to moving traffic.
- The empty bottle or the receipt shows us the fluid and the quantity, so don't bin it out.
- Our van locates you quickest with a postcode starting LL14 4, or simply the name of a street nearby, so phone from the spot.
Do not:
- Not even for a second, and not to roll your car: your motor remains off.
- Many diesels run their fuel pump the instant your ignition comes on, and so leave it off.
- No more fuel added. The AdBlue won't blend, and so it's wasted.
- Any driving at all is best avoided, including a short distance down Bersham Road.
- No emptying it yourself, at all, on the roadside.
Moving the car off the pumps is a job for staff to help with, wherever Ddol forecourt you're on, the Esso or any other. At home, the vehicle stays exactly as it is.
What does AdBlue do in a diesel tank?
Not the motor but the exhaust is where AdBlue belongs. Its own tank holds it, and from there it is fed into the exhaust, and there it treats the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.
Fuel blends; AdBlue, once poured in, won't. Its behaviour is nothing like diesel's. It drops, because it's heavier than diesel, and settles low where the pickup draws its fuel from. A car filled on a drive in Bryn Offa yesterday evening and left unstarted is the straightforward one. No pump has sucked the AdBlue up so far — though when the motor turns, that is what is pulled first, straight from the bottom of the tank.
Two kinds of damage follow from there. Crystals and corrosion. As the water dries, it leaves urea that crystallises in filter elements and tiny channels; meanwhile, since it eats at some metals, every part it reaches suffers for as long as it remains inside. Where the AdBlue has reached the pipework, waiting till morning around Ddol leaves things worse. In the tank alone, time does nothing. Diesel lubricates the high-pressure pump and each injector as it flows; water offers none of that, and that is a second form of damage.
Why is AdBlue in a diesel often the bigger issue?
Put petrol in a diesel at the Morrisons and you have an issue of thin fuel. Harm just comes from driving on it. Mixed into the diesel and sitting inside your tank, it causes none.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. It does not burn, so it cannot just be run through. Whether your car is in Felin Puleston or the centre of Ddol, turning it over "to see" costs more with AdBlue than almost any other mistake, and the flush counts for more. Why: it will not stay blended, and so watering it down fails; and deposits and corrosion survive the next tankful.
The same good news holds as with petrol. Never run? Then the AdBlue sits only in that tank, the simplest section of the entire system to clear, wherever your car has stopped across Wrexham.
How does AdBlue end up in a diesel tank around Ddol?
It is not on purpose. Many cars keep the AdBlue cap alongside the diesel inlet, occasionally under one flap, and mixing them up is simple after dark. It usually takes place at home, from a bottle bought on the journey home, rather than at the filling station.
The ways it happens are few and familiar. A warning light comes on during the school run, and the top-up occurs in a hurry outside the local primary school. In the evening, a bottle is tipped in on a driveway close to Berse Lane. Otherwise, after dark outside The Black Lion Inn, the vehicle gets refilled by a driver opening that flap for the first time.
The least familiar cars get it most — hire cars, new ones, fleet cars, and the other motor in a family with both fuels. Keep it switched off: that's the first response to the same slip, wherever in Ddol or the remainder of Wrexham you happen to be.
Started the engine with AdBlue in the diesel tank in Ddol?
Then the AdBlue has left the tank. It's been pulled through your filter and the lines, and if the engine ran for any time, it has reached the high-pressure pump and the injectors.
Maybe returning from Pool Covert, or midway across Ddol, your engine may run lumpy, smoke, drop power, flash your dash or stall. Stop as soon as it is safe, switch off, and do not restart the car to check. More of it is pulled through with each start.
On the M53, under 15 miles from Ddol, the first junction is where to exit, and anywhere safe is where to stop — not driving on.
Every mile carries the AdBlue deeper into the system. That's why crossing Ddol to park beside Bersham Ironworks and a drive of under 3 miles towards Wrexham are very different jobs. Roughly how far had it come? Tell us.
Once the engine has been run, the flush covers more, and all of it is done where the car has ended up. Very rarely does it leave lasting damage if it's caught quickly.
Ddol: how AdBlue is cleared from a diesel
A road by Holy Trinity, a driveway, a lay-by or a filling station: wherever your car has come to rest in Ddol, our technicians come to it. Which fluid went in, about how much, and if your motor has turned over: we check first, because those shape the work.
On the spot, that tank is then emptied, and all of the contaminated diesel and the urea come out at once. With AdBlue, more so than with petrol, flushing matters: the whole system is cleaned all the way through because residue won't flush out by itself. Next, the filter: cleaned, or replaced if it has to be. Then fresh diesel, then a check of your vehicle. About half an hour once we arrive is usual for most jobs when the motor hasn't run. The pumping gear is explosion-proof, and so a busy filling station is no fault, and it's quiet enough for a residential street late at night.
Fresh diesel goes in to prime your system, and that is the final step. You head off as soon as we have fired it up, and it makes no difference whether your car is on a driveway in Ddol or in a bay at Wrexham General. The test before we go is that it runs smoothly on clean diesel. No garage is required at any point, with the whole job done on the spot. Your insurer is likely to want an engineer's report and your VAT invoice — both yours afterwards.
About Ddol, briefly
Ddol is a small village situated on the riverside in Wrexham county, with a population of around 1296 people. Ddol has a mix of housing types, but semi-detached homes are the most common, and it is located near other villages such as Bersham and Rhostyllen. Ddol sits at an elevation of 105 metres, close to the city of Wrexham, which is just 1.7 miles away. Ddol is part of a wider area that includes Pentre Bach and other local communities.
AdBlue drains across Ddol and Wrexham
Over the LL postcode area, the teams answering AdBlue call-outs in Ddol reach much of Wrexham as well, Bersham, Rhostyllen and Pentre Bach included. Guessing doesn't help close to a border or somewhere tricky to describe; ring and ask.
Anywhere your vehicle sits — a drive at home, a side street, a car park, a forecourt — our engineers empty it there, and there's no need to take it to us; that suits Ddol, a village, well.
AdBlue in a diesel tank around Ddol: the cost of fixing it
Each job differs, and so not one fixed quote is fair. Three things shift the cost: whether the engine has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one comes down to whether a technician can get to it safely, and an open driveway is simpler than a tight spot behind Clywedog Leisure and Activity Centre.
That is why each call from Ddol starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it has run. When those are known, a range becomes a single fixed figure.
You hear that quote by phone, before anyone sets off, and you pay on the day, by card or over the phone, with nothing upfront. Misfuelling cover is part of plenty of insurance policies, so it is worth looking at yours before the van arrives.
Still next to the vehicle in Ddol?
Then, the most helpful thing to do with your car is to leave it. Keys out, motor off, ignition off. Petrol in Diesel takes over the remainder, across Ddol or anywhere in Wrexham, once you ring 0333 366 0103 saying it was AdBlue, roughly how big an amount, and whether the engine ran.
