Cockett: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in the diesel tank, the ignition remains off and so does your motor. Chemically, AdBlue is just urea in water. Not like fuel, it neither burns nor blends, and nothing happens till the engine pulls it through. In Cockett, AdBlue in a diesel tank caught before your motor runs usually comes down to a drain and a thorough flush, right where the vehicle is. Before you do anything else, phone 0333 366 0103.
Cockett, AdBlue in your diesel tank: what to do at once
To do:
- Take the keys out, so no one switches the ignition on.
- Put the hazard lights on if you are at all close to moving traffic.
- Hold on to your receipt or the empty bottle, and so you can tell us what got in and roughly how much.
- The van locates you quickest with a postcode starting SA5 5, or simply the name of a street nearby, so phone from the car.
Do not do these:
- No starting your engine — not for a second, not to reposition your car.
- Turning the key to ignition by itself sets the pump running on many diesels. Avoid it.
- Pouring in extra diesel does not work: AdBlue settles out instead of thinning.
- Any driving at all is best avoided, even a short stretch up Cwmbach Road.
- No draining it yourself, either, on the roadside.
On a forecourt in Cockett, whether it is the Applegreen or another one, ask the staff to help you roll your car away from the petrol pump. On that drive, the vehicle stays exactly as it is.
AdBlue in a diesel tank, and what it does there
The engine is not what AdBlue is made for; your exhaust is. From a separate tank it goes directly to your exhaust, cleaning what your motor emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.
Fuel mixes; AdBlue, once poured in, will not. The behaviour is nothing like diesel's. It's heavier than diesel, so it sinks and collects at the bottom of that tank, which is where the pickup sucks fuel from. Once your system runs, the AdBlue is top of the list to go through. Until then it waits beneath the diesel, which is how a vehicle filled in Caer-eithin yesterday and not started remains the straightforward case, provided no one turns the key.
From there it does two kinds of damage. Crystals and corrosion. As the water dries, it strands urea that hardens in filters and tiny channels; meanwhile, because it eats at certain metals, each part it reaches suffers for as long as it remains inside. A vehicle left sitting around Cockett with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Diesel lubricates the high-pressure pump and each injector as it passes; water gives no lubrication, and that is a separate form of harm.
Why is AdBlue in a diesel frequently the bigger fault?
Top up a diesel with petrol in error at the Texaco, and the issue is thinned fuel. Damage only comes from running on it. Mixed into the diesel and sitting inside your tank, it causes none.
With AdBlue in a diesel, the liquid as such is plainly the wrong one. Not burning, it can't simply be run through. Nor can it be watered down, because it separates back out — and the next fill won't clear away crystals or corrosion. So the flush counts for more here, and turning the key "to see", in the heart of Cockett or out in Cwmdu, costs more than nearly any other mistake.
With AdBlue, the good news is no distinct from petrol. Never started? Then the AdBlue sits just inside the tank, the easiest section of the whole system to clear, anywhere your vehicle has come to rest in Swansea.
How AdBlue ends up in a diesel tank in Cockett
Many motors place the AdBlue filler alongside the diesel one, now and then under one flap, and in dim light the two may look the same. No one intends it. Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the pump.
It tends to take place in a few familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside the local primary school. A bottle is poured in at the end of the day on a drive just off Clos Aneira. Otherwise, in dim light outside Marquis Arms, the car is topped up by a driver using that flap the first time.
The least familiar cars get it most — hire cars, brand-new cars, company cars, and the other car of a home with one of each fuel types. Anywhere across Swansea, Cockett included, the slip doesn't change, and neither does the first response: keep it switched off.
Already started the engine with AdBlue in your diesel tank around Cockett?
Then that tank is no longer where the AdBlue is. With any running time, it goes on to the high-pressure pump and every injector, having passed through the filter and pipework.
Watch for rough running, smoke, falling power, lights on the dash, or a cut-out — returning from Ravenhill Park, perhaps, or part way across Cockett. Stop when it is safe. Switch off. Keep it off rather than testing it again. Each start pulls more of that through.
Exit the M4, under 3 miles from Cockett, by the next junction and stop somewhere safe, rather than driving on.
How far it went counts. A couple of hundred yards across Cockett to the car park by The Church of Jesus Christ of Latter-day Saints is a very different job from a run towards Swansea, under 3 miles away, with the AdBlue reaching further into the fuel system with every mile. Tell us roughly how far it had come.
There's more to clean out once your engine has been started, and our engineers do all of it where the vehicle has ended up. If it's spotted soon, long-term damage is very unusual.
Cockett: how AdBlue is emptied from a diesel
The car stays where it is, whether that is a street near Saint Peter's Church, a driveway, a lay-by or a forecourt in Cockett, and the van comes to it. The job rests on three replies, and our engineers get before all else — which fluid got in, the quantity, and if the engine has turned over.
Then your tank is cleared where the vehicle stands, and so the contaminated fuel and the AdBlue come out together. What remains from AdBlue will not flush away unaided, so the whole system gets a full flush, which matters far more here than for petrol. Fresh diesel goes in once your filter is cleaned — or swapped, if it needs to be — and then your car is tested. Engine not run? In that case count on about half an hour on site for most jobs. Quiet enough to use outside a house at night, and fine on a busy forecourt, our pumps are explosion-proof.
Bleeding the system with new diesel comes at the end. You head off as soon as we have started the engine, and it makes no difference whether the vehicle is on a driveway in Cockett or in a space outside Swansea. It is checked on new diesel to make sure it runs smoothly before our engineers leave. Because the job is done in its entirety where the car is, a garage never comes into it. Your insurer is likely to want an engineer's report and the VAT invoice — both yours once this job is done.

AdBlue drains across Cockett and Swansea
AdBlue jobs in Cockett go to vans that serve the towns near it — Raven Hill, Gendros plus Fforest-fach — and most of Swansea beyond, throughout SA postcodes. Ring and ask rather than guess when you are by a border, or anywhere tricky to pin down.
Anywhere the vehicle stands — a drive at home, a side street, a parking area, a filling station — our technicians empty it there, with no need to take it to us; that suits Cockett, a residential suburb, well.
What AdBlue in a diesel tank costs to put right in Cockett
Each job is different, and so no fixed price would be fair. What moves the cost is, firstly, whether your engine has run and for how long; then how much AdBlue got in; and after that where the vehicle is and whether our van can get to it safely, which is simpler on an open driveway than in a tight space behind Cockett Standing Stone.
Ahead of a figure, not afterwards, each call from Cockett begins with three questions: the fuel, the quantity, and if it ran. Those answers turn a range into a straight price.
Before anyone sets off, you hear our quote by phone. And you pay on the day, card or over the phone, with nothing in advance. While our engineer is on the way, check your insurance: many cover misfuelling.
Next to the car in Cockett, still?
Leaving your vehicle alone is, right now, the best thing open to you. Ignition off, engine off, keys out. Phone 0333 366 0103 then tell us it's AdBlue, roughly how much, and whether it has run. Petrol in Diesel takes it from there, around Cockett or anywhere around Swansea.
