AdBlue in a Diesel Tank in Arnos Grove? Don't Start It
With AdBlue in the diesel tank, the ignition remains off and so does the engine. Urea dissolved in water is all AdBlue is. It does not burn, it does not mix with diesel, and the harm it does begins when your fuel system draws it in. In Arnos Grove, AdBlue in a diesel tank found before the motor runs normally comes down to a drain and a thorough flush, just where your car is. Before you do anything else, phone 0333 366 0103.
AdBlue in your diesel tank around Arnos Grove: the first few minutes
Things to do:
- So no one can turn your ignition on, pull the keys away.
- If you are anywhere close to moving traffic, put the hazard lights on.
- The empty bottle or the till receipt tells us the fluid and the amount, so don't throw it out.
- Give us a postcode starting N11 1, or whatever street lies nearest, and our van reaches you directly — so ring from wherever you are.
Not to do:
- Not even briefly, and not to roll your car: your engine stays off.
- Turning the key to ignition alone sets your pump going on many diesels. Skip it.
- Pouring in more diesel does not work: AdBlue separates out rather than blending.
- Never drive it anywhere, not even a short stretch down Seafield Road.
- By the road, do not try draining it yourself.
The attendants on duty at any Arnos Grove forecourt — the BP among them — will normally help rolling it aside if you ask. Stopped on your own driveway? Then it remains exactly as it is.
What does AdBlue do in a diesel tank?
AdBlue is made for your exhaust, not the engine. Its own reservoir keeps it, and from there it's fed into your exhaust, where it treats the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.
Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. It is heavier than diesel, and so it sinks and gathers at the bottom of your tank, which is where the pickup sucks fuel from. A motor filled on a driveway in Southgate overnight and not started since counts as the straightforward case. Nothing has sucked the AdBlue up yet — though when your motor turns, that's what goes first, directly from the bottom of the tank.
From there it does two kinds of harm. 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 labouring on the components it hits for as long as it stays there. Lines holding AdBlue mean damage by morning for a vehicle parked in Arnos Grove. Just inside that tank, it stays stable. Water lubricates nothing. The high-pressure pump and every injector need diesel running past them, so the water content harms them in its own right.
Why is AdBlue in a diesel frequently the bigger fault?
Put petrol in a diesel at the Bounds Green Service Station and you have a fault of thin fuel. No harm comes as long as it sits put, mixed into the diesel — only when the engine runs on it.
The trouble with AdBlue in a diesel is a totally wrong liquid. It can't just be run through, since it doesn't burn. Deposits and corrosion stay after the next tankful, and AdBlue splits back out of your diesel, and so thinning it can't work. That is why the flush matters so much, and turning the key "to see" costs more with AdBlue than almost any other slip — in Osidge or the heart of Arnos Grove equally.
The same good news applies as with petrol. Anywhere around Greater London your car has come to rest, an unstarted engine means the AdBlue yet inside the tank: the easiest part of a fuel system to clear.
How AdBlue ends up in a diesel tank around Arnos Grove
It's not on purpose. Many vehicles keep the AdBlue inlet alongside the diesel inlet, now and then behind a single flap, and muddling them up is easy after dark. It mostly happens outside the house, from a container grabbed en route home, rather than at the forecourt.
Mostly, it takes place in one of a couple of familiar ways. Midway through the drop-off, the dashboard warns, and outside Bowes Primary School the top-up is hurried. A bottle is poured in at the end of the day on a drive just off Bowes Road. Else, in dim light by Arnos Arms, your car is topped up by someone opening that flap for the first time.
It comes up the most in a rental, a new vehicle, a fleet car, or the spare car of a family with one of each fuels — the cars drivers use the least. Wherever around Greater London, Arnos Grove included, the slip does not change, and nor does the first step: leave it off.
Started your engine with AdBlue in the diesel tank around Arnos Grove?
If so, the AdBlue is no longer in that tank. The fuel filter and pipework have had it sucked through, and some running carries it on to the injection pump and every injector.
Maybe coming back from Arnos Park, or midway across Arnos Grove, your engine may go lumpy, smoke, lose pace, light up your dash or stall. Stop as soon as it is safe, switch off, and don't restart it to check. With each start, more of that is pulled through.
If you were on the M1, under 5 miles from Arnos Grove, come off at the next junction and stop somewhere safe rather than pressing on.
Hopping across Arnos Grove to the car park by Arnos Pool is one matter; driving towards London, under 10 miles away, is another, since each mile carries the AdBlue deeper in. So mileage counts. About how far it had come is worth telling us.
There's more to rinse out once the motor has run, and we do all of it where your car has stopped. If it's spotted early, lasting damage is very uncommon.
Draining AdBlue in a diesel around Arnos Grove: what it takes
Our engineers come to the vehicle, wherever it has stopped in Arnos Grove: a side street close to Arnos Library, a drive, a lay-by or a forecourt. Before anything else we ask what got in, roughly how much, and if your motor has been run, because those answers settle this work.
The polluted diesel and the urea leave together after your tank is drained, right there. With AdBlue, far more than with petrol, the flush matters: the whole system is cleaned right through because residue won't flush out by itself. A test of your car comes at the end, after clean diesel is added and the filter gets cleaned or, where needed, swapped. Most of these jobs are a half-hour visit once our engineers turn up, if your motor hasn't run. Low-noise enough to use outside a house at night, and fine on a busy forecourt, our pumps are explosion-proof.
The last step is to prime your system on new diesel. After that our engineers start the car and you set off, whether from a parking bay at New Southgate or a drive in Arnos Grove. The check before we go is that it runs correctly on new diesel. Our engineers do it all wherever the vehicle has stopped, and it never has to be taken to a garage. The insurer is likely to want an engineer's report and your VAT invoice — each handed over afterwards.

What does AdBlue in a diesel tank cost to sort out around Arnos Grove?
Since each jobs vary, a flat price wouldn't be fair. Whether the motor has run, and for how long, comes first in what shifts the price.

That's why each call from Arnos Grove starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it's run. With those replies, the range narrows to a single firm figure.
