New Town: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in the diesel tank, the ignition remains off and so does your engine. AdBlue is urea dissolved in water. Not like fuel, it neither ignites nor blends, and no harm happens until your motor pulls it through. A drain and a thorough flush, done where your car is around New Town, is usually what AdBlue in a diesel tank takes — if it is caught before the motor has been run. Before you do anything else, call 0333 366 0103.
New Town, AdBlue in your diesel tank: what to do right away
Do these:
- Take the keys out, so no one switches your ignition on.
- Near moving traffic? Then put the hazards on.
- Which product, and roughly how much volume? Hang on to the bottle or the receipt, and our engineers will see.
- Ring us from where you are. A postcode starting CM23 3, or the name of the nearest street, gets our van to you without a search.
Things not to do:
- Not even for a second, and not to roll your car: your engine stays off.
- Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.
- No more fuel on top. The AdBlue won't blend, so it's pointless.
- Any driving at all is to be avoided, including a short distance along Royal Oak Gardens.
- Draining that tank yourself beside the road isn't one to try.
Ask the attendants to help you roll the car away from the pumps if you're on a forecourt around New Town, whether it's the Shell or somewhere else. Parked on your own drive? Then it stays exactly where it is.
AdBlue in a diesel tank: what it does
The engine is not what AdBlue is made for; the exhaust is. From a dedicated tank it is fed directly to the exhaust, treating what the engine lets out. Neither side fits the other: urea doesn't belong in a pump, and a pump cannot deal with urea.
Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. Denser than diesel, it sinks and collects below it — the same place the intake sucks from. Once the system runs, the AdBlue is top of the list to go through. Before then it waits underneath the diesel, and that is how a vehicle topped up in Thorley last night and never switched on remains the simple one, provided no one turns your key.
It does two kinds of harm from there. Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filter elements and narrow channels; and, because it eats at certain metals, each part it reaches suffers for as long as it stays in there. If the AdBlue has reached the lines, leaving it till morning around New Town makes it worse. In that tank alone, waiting does nothing. And there's the water: it offers no protection to the parts that need it most — the injection pump and every injector.
Why AdBlue in a diesel is commonly more significant than petrol
Petrol put into a diesel on Sainsbury's's forecourt leaves your fuel thin — that's the main issue. No harm is done as long as it stays unused, blended into your diesel — only once your motor runs on it.
AdBlue in a diesel is an issue of the wrong substance altogether. It doesn't burn, and so it can't just be run through. Whether the vehicle sits in Thorley Houses or the centre of New Town, turning it over "to see" does more harm with AdBlue than nearly any other error, and the flush matters for more. Why: it will not remain mixed, and so diluting it fails; and deposits and corrosion survive the next tankful.
With AdBlue, the good news is no distinct from petrol. Wherever in Hertfordshire your car has come to rest, an unstarted motor leaves the AdBlue yet in the reservoir: the simplest bit of a fuel system to clear.
How AdBlue ends up in a diesel tank around New Town
In dim light, two caps together — the AdBlue one and the diesel cap, now and then behind one flap — may look the same. No one means it; plenty of layouts invite it. It mostly occurs at home, from a bottle bought en route home, not at the filling station.
The ways it occurs are few and familiar. Halfway through the morning drop-off, the dashboard flags it up, and outside St Michael's Church of England Primary School the refill is hurried. After work, a container is tipped in on a drive close to Middle Row. Else, after dark outside The Castle, the car is refilled by someone using that flap the first time.
The least known cars see it most — hire cars, new cars, fleet ones, and the spare vehicle of a home with one of each fuel types. Wherever you are around New Town or the rest of Hertfordshire, it's the same mistake and the same first answer: leave it off.
Started the engine with AdBlue in your diesel tank around New Town?
Then the tank is no longer where the AdBlue is. Given any running, it travels to the injection pump and every injector, after passing via the fuel filter and pipework.
Rough running, smoke from the exhaust, dropping power, dashboard warnings or stalling: each may show up, perhaps part way across New Town or returning from The Firs. No restarting to test: stop once it is safe, then turn everything off. Each start pulls more of that through.
On the M11, under 3 miles from New Town, the next junction is where to exit, and anywhere sensible is where to stop — not carrying on.
Each mile carries the AdBlue deeper in. That's why a hop across New Town to park beside Holy Trinity Church and a drive of under 25 miles for Chelmsford are very different jobs. About how far it had come is worth telling us.
Once the engine has run, the flush includes more, and all of it is done where the vehicle has stopped. Spotted soon, it very seldom leaves permanent damage.
New Town: how AdBlue is cleared from a diesel
The vehicle stays where it is, whether that's a street beside Bishop's Stortford Methodist Church, a driveway, a layby or a forecourt around New Town, and the van comes to it. The work depends on three replies, and our technicians ask for first — what was put in, the quantity, and if the engine has turned over.
Next, draining the tank right there takes out the contaminated diesel along with the AdBlue together. The system is flushed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. A test of your car follows last, once fresh diesel is added and the filter is cleaned or, if necessary, swapped. The majority of these jobs are a half-hour job once our engineers get there, provided the motor hasn't run. The pumping gear is explosion-proof, and so a busy forecourt is no problem, and it is quiet enough for a residential street after dark.
Clean diesel goes in to prime your system, and that is the final step. You drive off as soon as our engineers have fired it up, and it makes no difference whether the vehicle is on a drive in New Town or in a space at Bishops Stortford. Before we go, we confirm it is running properly with new diesel in. As the job is done in full where the vehicle is, a workshop never comes into it. Your insurer will want an engineer's report and your VAT invoice — both yours once the job is done.

AdBlue drains in New Town and across Hertfordshire
Over the CM postcode area, the vans taking AdBlue call-outs around New Town serve much of Hertfordshire as well, Bishops Stortford, Hockerill and Thorley Street among them. If you are close to a border, or somewhere hard to describe, ring and ask rather than guessing.
A van that comes to you fits New Town, a residential suburb: there's no need to take your car to us, since we empty it on the spot, on a driveway, a side street, a parking area or a forecourt.
New Town: what AdBlue in a diesel tank costs to fix
Because each callouts differ, a single price would not be fair. Whether the engine has run, and for how long, comes first in what changes the cost. How much AdBlue was put in comes next, and then the location of the vehicle, because an open driveway is simpler for a technician to get to safely than a tight gap behind The Hub Church.
Which fluid was put in, what quantity, and if the engine ran: each New Town enquiry begins with exactly that, ahead of a figure, never after. Those replies turn a range into a straight price.
You get that quote on the phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront. As the van is on the way, check your insurance: many cover misfuelling.
