Don't Start It: AdBlue in a Diesel Tank in Chipping Barnet
If AdBlue has gone into the diesel tank, keep the motor off and keep the ignition off. Urea dissolved in water is what AdBlue is. Unlike fuel, it neither burns nor mixes, and no harm happens until your engine sucks it through. Caught before your engine has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the car is in Chipping Barnet. Before you do anything else, ring 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank in Chipping Barnet
Things to do:
- Keys out — then nobody can power anything on.
- Hazards on, if moving traffic is anywhere near.
- Hold on to the till receipt or the empty bottle, and so you can tell us what was put in and roughly how much.
- Call us from where you are. A postcode starting EN5 4, or the name of the closest street, gets our van to you without a search.
Things not to do:
- Shifting the car even a few yards is no reason to fire up your engine.
- Switching the key to ignition alone starts the pump running on many diesels. Avoid it.
- No extra fuel added. The AdBlue won't blend, so it's pointless.
- Do not drive the vehicle anywhere, not even a short distance along Ravenscroft Road.
- Draining the tank on your own by the road is not worth trying.
Get the people behind the counter to help you move the car away from the island if you're at a forecourt in Chipping Barnet, whether it is the Esso or somewhere else. At your own driveway, don't touch it at all.
AdBlue in a diesel tank: what it does
Made for your exhaust, AdBlue has no place in your engine. It goes into its own tank and is sprayed into your exhaust gas to fresh it. Nothing in a fuel pump is designed for this fluid — and no part of that was meant to travel through one.
It doesn't blend. After it's poured into a tank of diesel, AdBlue acts nothing like diesel. It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup pulls fuel from. Simplest of all: one that got AdBlue in Ducks Island overnight and has not been started since. The liquid waits at the base of that tank, undrawn — though it will be the first thing through once your motor starts, ahead of any diesel at all.
Two kinds of damage follow 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, so it keeps working on the components it reaches for as long as it stays there. A motor left standing around Chipping Barnet 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: the 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 serious than petrol
Put petrol in a diesel at the BP and you have an issue of thin fuel. It mixes with the diesel, and while it is in the tank it causes no damage; the harm comes from running the engine on it.
The issue with AdBlue in a diesel is a totally wrong liquid. Not burning, it can't just be run through. Whether your vehicle is in Arkley or the heart of Chipping Barnet, firing it up "to see" costs more with AdBlue than nearly any other error, and the flush matters more. Why: it will not remain mixed, so diluting it is impossible; and deposits and corrosion survive the next tankful.
As with petrol, there's good news. Never started? Then the AdBlue sits just in your tank, the simplest bit of the entire system to empty, wherever the car has come to rest in Greater London.
AdBlue in a diesel tank around Chipping Barnet: how it ends up there
After dark, two caps side by side — the AdBlue one and the diesel one, now and then behind one flap — may look the same. Nobody means it; many designs invite it. Usually it is never the filling station: someone picks up a bottle heading home and tips it in at home.
Usually, it occurs in one of a few familiar ways. Hurrying, outside Foulds School, after a warning light flashed on during the school run, a parent tops up your car. A bottle is poured in at the end of the day on a drive just off Union Street. Another pattern: darkness, the car park outside The Black Horse, and a driver using that flap for the first time.
It comes up most in a hire car, a new vehicle, a company car, or the other car of a family with one of each fuels — the vehicles people know least. Wherever you're in Chipping Barnet or the remainder of Greater London, it's the same error and the same first answer: leave it off.
Chipping Barnet: started the engine with AdBlue in your diesel tank?
If so, the AdBlue is no longer in the tank. With any running time, it travels to the injection pump and every injector, after passing via the fuel filter and lines.
Expect rough running, exhaust smoke, falling power, lights on your dash, or a cut-out — coming back from Ravenscroft Park, say, or midway across Chipping Barnet. No restarting to check: pull over when it is safe, then switch it off. More of it is pulled through with each start.
On the M25, under 3 miles from Chipping Barnet, the next junction is where to leave, and somewhere safe is where to park — not carrying on.
Mileage matters: each mile carries the AdBlue deeper into the system, so heading for St Albans, under 10 miles away, gives a much bigger job than hopping across Chipping Barnet to the car park by Mary Immaculate & St Gregory the Great. Roughly how far had it come? Tell us.
Once the motor has been started, the flush covers more, and all of it is done where the vehicle has ended up. Spotted early, it very rarely leaves permanent damage.
Draining AdBlue in a diesel in Chipping Barnet: what it takes
Our technicians come to the vehicle, wherever it has stopped in Chipping Barnet: a side street near Barnet United Reformed Church, a drive, a lay-by or a forecourt. Before anything else our engineers ask what went in, roughly how much, and whether the motor has run, since those answers determine the work.
The polluted diesel and the urea come out together after your tank is drained, on the spot. Residue from AdBlue won't flush away unaided, so the fuel system gets a careful flush, which counts far more here than for petrol. Next, the fuel filter: cleaned, or replaced when it has to be. After that clean diesel, then a check of the car. Not run? Then count on about half an hour on site for most jobs. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house after dark.
Priming the system with fresh diesel comes last. Whether it's a parking space outside New Barnet or a drive in Chipping Barnet, that is where our technicians fire it up and you set off. Before we leave, we make sure it's running properly with fresh diesel in. We do it all wherever your car has stopped, and it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come afterwards.

What does AdBlue in a diesel tank cost to sort out in Chipping Barnet?
Because each jobs differ, a single figure would not be honest. Three things move the cost: whether the motor has been running and for how long, how much AdBlue went in, and where the car is. That last one rests on whether a technician can reach it safely, and an open driveway is simpler than a tight spot behind Ravenscroft Lawn Tennis Club.
