AdBlue in the Diesel Tank in Sunnyside? Keep It Switched Off
Motor off, ignition off: that is where you start if AdBlue has gone into the diesel tank. Chemically, AdBlue is simply urea in water. Not like fuel, it neither ignites nor mixes, and no harm starts till the engine sucks it through. In Sunnyside, AdBlue in a diesel tank caught before your motor runs normally means a drain and a thorough flush, just where the car is. Before you do anything else, call 0333 366 0103.
Sunnyside, AdBlue in the diesel tank: what to do straight away
Do these:
- Remove the keys, which prevents anyone switching the electrics on.
- If you're at all close to moving traffic, put the hazards on.
- So you can give us which fluid it was and roughly how much, save your receipt or the empty bottle.
- Ring us from where you are. A postcode starting SG4 9, or the name of the closest street, gets our van to you without a search.
Things not to do:
- No starting the motor — not for a second, not to shift the car.
- Don't switch your ignition on. On many diesels that alone runs the fuel pump.
- Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
- Never drive the car anywhere, not even a short distance along Maytrees.
- No draining it yourself, at all, at the verge.
On a forecourt in Sunnyside, whether it is the BP or another one, ask the attendants to help you roll your car away from the petrol pump. Parked on your own drive? Then it remains just as it is.
AdBlue in a diesel tank: what it does
Meant for the exhaust, AdBlue has no business in your engine. From a separate reservoir it is fed straight to your exhaust, treating what your engine emits. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.
It doesn't blend. After it is tipped into the tank, AdBlue acts nothing like fuel. The pickup sucks fuel from the lowest part of your tank, and that's exactly where AdBlue settles: as it is denser than diesel, it sinks. Once the pump runs, the AdBlue is first to go through. Before then it sits underneath the diesel, and that is how a car filled in Ashbrook yesterday and not switched on remains the simple one, as long as no one turns your key.
It does 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 is corrosive to some of the metals a fuel system is made from, and so it keeps working on the parts it gets to for as long as it remains there. A car left sitting around Sunnyside with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. The water in it does harm of its own: the high-pressure pump and the injectors depend on diesel to lubricate them, and water offers them nothing.
Why AdBlue in a diesel is often more serious than petrol
Petrol pumped into a diesel on Esso's forecourt leaves the fuel thin — that's the whole problem. Mixed into the diesel and sitting unused, it is no threat at that stage; using the motor is the damage.
AdBlue in a diesel is another problem: not thin fuel, yet no fuel at all. It cannot just be run through, since it does not burn. Deposits and corrosion remain after the next tankful, and AdBlue separates back from your diesel, and so thinning it can't work. Hence the flush counts so much, and turning your key "to see" costs more here than nearly any other mistake — in Charlton or the heart of Sunnyside alike.
As with petrol, there is good news. Never started? Then the AdBlue sits only inside that tank, the easiest bit of the entire system to clear, anywhere your vehicle has stopped across Hertfordshire.
AdBlue in a diesel tank around Sunnyside: how it ends up there
It's not deliberate. Plenty of cars keep the AdBlue cap alongside the diesel one, occasionally behind one flap, and muddling them up is easy after dark. Most of the time it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.
It tends to take place in a couple of familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside Whitehill Junior School the top-up is rushed. In the evening, a container is tipped in on a driveway close to Whitegale Close. Else, after dark by The Orange Tree, the vehicle gets refilled by someone opening that flap for the first time.
The least known vehicles see it the most — rentals, new cars, fleet cars, and the spare car in a home with one of each fuels. Wherever you are in Sunnyside or the rest of Hertfordshire, it's the same mistake and the same first answer: leave the car off.
Already started the engine with AdBlue in your diesel tank around Sunnyside?
The AdBlue has left your tank, then. Via your filter, along the pipework, and — with any running time — into the high-pressure pump and every injector: that's where it travels.
Expect lumpy running, smoke, lost power, warnings on the dash, or a cut-out — returning from Windmill Hill, say, or part way across Sunnyside. Stop when safe. Turn off. Leave the car off rather than restarting it to check. More of that is pulled through with each start.
Sunnyside sits under 3 miles from the A1(M); if you were on it, leave by the first junction and stop safely instead of driving on.
Mileage counts: each mile pushes the AdBlue deeper into your system, so driving towards St Albans, under 15 miles away, makes a much larger job than crossing Sunnyside to the car park by St John's Community Centre. Let us know about how far it had come.
Our engineers do all of the cleaning where the car has ended up, and once your engine has been run there is more of it. Very rarely does it leave permanent damage if it's noticed soon.
Sunnyside: how AdBlue is drained from a diesel
Our engineers come to the car, wherever it has stopped around Sunnyside: a side street close to Grace Baptist Church, a drive, a lay-by or a forecourt. The job depends on three answers, and our engineers ask for before all else — which fluid went in, the amount, and if the motor has turned over.
The contaminated diesel and the urea leave as one after that tank is drained, on the spot. A careful flush matters far more with AdBlue than after petrol, because what remains won't wash out on its own. Next, your filter: cleaned, or changed if it must be. After that fresh diesel, and then a check of the car. Not run? In that case count on about half an hour once we are there for most jobs. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house after dark.
The last step is to bleed your system on clean diesel. Firing it up comes next, and then you set off from where your car is parked, at Hitchin or on a drive around Sunnyside. The test before we leave is that it runs correctly on clean diesel. The entire job is done where your car is, so it never needs to be taken to a workshop. Insurers want a VAT invoice and an engineer report, and both come at the end.

What does AdBlue in a diesel tank cost to sort out around Sunnyside?
There's no honest single quote, since the jobs are not the same. What changes the price is, first, whether your engine has been running and for how long; then how much AdBlue got in; and after that where your car is and whether our van can get to it safely, which is simpler on an open drive than in a tight space behind British schools museum.
What got in, how much, and whether the engine ran: each Sunnyside enquiry opens with exactly those, ahead of any quote, never after. With them, a range narrows to a single fixed figure.
You hear that price by phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van arrives.
