AdBlue in the Diesel Tank in Upper Cwmbran? Keep It Switched Off
AdBlue in your diesel tank? Then keep your motor off — and the ignition as well. AdBlue is urea dissolved in water. The trouble starts once it is sucked through your pump — it will not burn, and it won't blend with diesel. If your engine has not run yet, AdBlue in a diesel tank is generally drained and carefully flushed where your car sits around Upper Cwmbran. First, call us on 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around Upper Cwmbran
Things to do:
- So nobody can turn your ignition on, take your keys out.
- Hazards on, if moving traffic is at all close.
- Which fluid, and roughly how much quantity? Hang on to the bottle or the till receipt, and our technicians can know.
- Give us a postcode starting NP44 5, or whatever street lies closest, and our van reaches you straight — so ring from wherever you stand.
Not to do:
- Do not start the engine, even for a moment to shift the vehicle.
- The ignition remains off: on many diesels, switching it on is enough to run your pump.
- Pouring in extra diesel doesn't help: AdBlue separates out instead of blending.
- Any driving at all is to be avoided, including a short way down Bethel Lane.
- No emptying it yourself, either, on the roadside.
Rolling the vehicle off the pumps is a job for attendants to help with, whichever Upper Cwmbran forecourt you are on, the Colley Motor Group or any other. Parked on your own driveway? Then it stays just where it is.
AdBlue in a diesel tank, and what it does there
Made for your exhaust, AdBlue has no business in the engine. Its own tank keeps it, and from there it is fed into the exhaust, where it treats the fumes. Nothing inside a fuel pump is made for this fluid — and none of that was meant to travel that way.
Tipped in with the diesel, it keeps apart instead of blending — entirely unlike fuel. The pickup sucks fuel from the lowest part of the tank, and that's just where AdBlue settles: as it is heavier than diesel, it sinks. When your system runs, the AdBlue is top of the list to go through. Before then it waits underneath the diesel, which is how a car filled in Lowlands yesterday and not switched on remains the simple case, as long as no one touches your key.
It causes two kinds of damage from there. What is left once the water evaporates is urea, which forms crystals: they settle in narrow passages and clog filters. Worse, it eats at some metals in a fuel system, and keeps going until it is flushed out. A car left standing in Upper Cwmbran with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. The water in it does damage of its own: your high-pressure pump and the fuel injectors depend on diesel to lubricate them, and water gives them nothing.
Why AdBlue in a diesel is regularly more major than petrol
An issue of thinned fuel is what you end up with after fuelling a diesel with petrol at the Sainsbury's. No harm is done while it stays unused, blended into the diesel — only once your engine works on it.
AdBlue in a diesel is another problem: not thin fuel, yet no fuel at all. Because it doesn't burn, running it through is not an option. It doesn't stay mixed, and so it cannot be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Greenmeadow or the middle of Upper Cwmbran.
The same good news holds as with petrol. Anywhere around Torfaen your car has come to rest, an unstarted motor means the AdBlue still in the tank: the easiest part of a fuel system to clear.
AdBlue in a diesel tank in Upper Cwmbran: how it ends up there
Nobody means to do it. The AdBlue filler on many motors waits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. It usually happens outside the house, from a container bought en route home, rather than at the filling station.
It tends to happen in a few familiar ways. The top-up is rushed outside the local primary school, because your dash lit up with a warning while the children were taken in. In the evening, a bottle is tipped in on a driveway near Thornhill Road. Else, after dark outside The Queen Inn, the car is refilled by a driver opening that flap the first time.
It takes place most in the motors drivers know least: a hire car, a new motor, a company car, or the second motor of a household with one diesel and one petrol. Wherever in Torfaen, Upper Cwmbran as well, the mistake doesn't change, and nor does the first step: leave it off.
Upper Cwmbran: started the engine with AdBlue in the diesel tank?
The AdBlue has left your tank, then. It's been pulled through the fuel filter and your lines, and if the engine ran for any time, it has got to the high-pressure pump and your injectors.
Lumpy running, smoke, lost power, dashboard warnings or cutting out: each may show up, perhaps part way across Upper Cwmbran or coming back from Pontnewydd Golf Course. No restarting to check: stop once safe, then switch it off. Every start pulls more of it through.
Leave the M4, under 5 miles from Upper Cwmbran, by the first junction and park somewhere safe, not carrying on.
A quick hop across Upper Cwmbran to the car park by Greenmeadow Community Farm is one thing; heading towards Newport, under 10 miles away, is another, because each mile carries the AdBlue deeper in. So mileage matters. Roughly how far had it come? Tell us.
Once your engine has been run, the flush takes in more, and all of it is done where the vehicle has stopped. Long-term damage is very uncommon when it's spotted soon.
What clearing AdBlue from a diesel involves in Upper Cwmbran
A street beside Fairhill Methodist Church, a driveway, a lay-by or a forecourt: wherever the vehicle has stopped in Upper Cwmbran, we travel to it. The job depends on three answers, which our engineers get first — which fluid got in, the amount, and whether the engine has turned over.
The contaminated diesel and the urea come out together when that tank is emptied, right there. A careful flush matters far more after AdBlue than with petrol, since what remains will not clear away by itself. Fresh diesel goes in after the filter is cleaned — or replaced, 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 working forecourt, the pumps are explosion-proof.
Clean diesel goes in to prime the fuel system, and that is the final step. Firing it up comes next, and then you head off from where the vehicle is parked, outside Cwmbran or on a driveway in Upper Cwmbran. The check before our technicians head off is that it runs correctly on clean diesel. As the job is done in full where the vehicle is, a garage never comes into it. At the end, you are given the paperwork for the insurer: a VAT invoice plus a report from the engineer.

Upper Cwmbran: what AdBlue in a diesel tank costs to fix
Since each jobs vary, a flat price would not be fair. Whether the engine has run, and for how long, comes first in what shifts the cost. How much AdBlue went in comes next, and then the position of the car, since an open drive is easier for a technician to reach safely than a tight gap behind TK Maxx.
