AdBlue in the Diesel Tank in Carpenders Park? Keep It Switched Off
AdBlue in the diesel tank? Then leave your motor off — and your ignition as well. Urea dissolved in water is what AdBlue is. It does not burn, it does not mix with diesel, and the harm it does starts when the system draws it in. In Carpenders Park, AdBlue in a diesel tank found before the motor runs normally means a drain and a thorough flush, just where the car is. Phone 0333 366 0103 before you do anything else.
What to do straight away, Carpenders Park: AdBlue in the diesel tank
Things to do:
- So no one can switch your ignition on, take the keys out.
- Hazards on, if moving traffic is anywhere close.
- The empty bottle or the receipt tells us the product and the amount, so don't throw it away.
- Call us from where you are. A postcode starting WD19 5, or the name of the closest street, gets the van to you without a search.
Don't do these:
- Don't start the motor, even for a moment to shift the car.
- Plenty of diesels power their fuel pump the moment your ignition goes on, and so keep the vehicle off.
- Don't top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
- Keep the car where it is rather than driving it anywhere, even a short way down Little Oxhey Lane.
- Beside the road, don't attempt draining it on your own.
Rolling the vehicle off the island is a job for staff to help with, wherever Carpenders Park forecourt you are on, the Esso or any other. If you're on your own drive, leave the vehicle just where it stands.
What does AdBlue do in a diesel tank?
Made for the exhaust, AdBlue has no business in the engine. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Neither side suits the other: urea does not belong in a pump, and an injection pump cannot take urea.
Fuel blends; AdBlue, once tipped in, will not. Its behaviour is nothing like fuel's. It drops, since it's denser than diesel, and settles low where the intake draws its supply from. A car filled on a drive in Watford Heath yesterday evening and left unstarted counts as the simple case. No pump has pulled the AdBlue up so far — though when the motor turns, that's what is pulled first, directly from the bottom of your tank.
From there it does two kinds of damage. It attacks some metals used in fuel components, attacking whatever it reaches until it is removed completely. And when the water evaporates, the urea forms crystals that clog filters and lodge in narrow passages. Where the AdBlue has reached the lines, waiting overnight around Carpenders Park leaves it worse. Inside the tank alone, waiting does nothing. And there's the water: it brings no lubrication to the parts that need it most — the high-pressure pump and every injector.
Why AdBlue in a diesel is frequently more major than petrol
Put petrol in a diesel at the Shell and you have an issue of thin fuel. Damage just comes from running on it. Blended into the diesel and left in the tank, it does nothing.
The trouble with AdBlue in a diesel is a completely wrong liquid. Not burning, it cannot simply be run through. Whether your car is in Pinner Green or the centre of Carpenders Park, firing it up "to see" does more harm in this case than nearly any other error, and the flush matters more. The reasons: it won't remain mixed, so watering it down fails; and deposits and corrosion survive the following tankful.
With AdBlue, the good news is no different from petrol. Emptying a tank is the simplest job on any fuel system, and with no start-up, the AdBlue stays in it — anywhere across Hertfordshire your vehicle has stopped.
Carpenders Park: how AdBlue ends up in a diesel tank
After dark, two caps side by side — the AdBlue cap and the diesel cap, now and then under a single flap — can look the same. Nobody intends it; many layouts invite it. Mostly it's not the filling station: a driver buys a bottle heading home and tips it in at home.
It tends to happen in a couple of familiar ways. Midway through the drop-off, the dashboard warns, and outside Woodhall Primary School the refill is hurried. A bottle is poured in at the end of the day on a drive just off Harrow Way. Otherwise, in dim light outside The Dick Whittington, the vehicle gets refilled by someone opening that flap for the first time.
It crops up the most in a hire car, a brand-new motor, a company motor, or the other motor in a family with both fuel types — the vehicles drivers use least. Leave it off: that is the first step to the same slip, wherever in Carpenders Park or the rest of Hertfordshire you happen to be.
Started the engine with AdBlue in your diesel tank around Carpenders Park?
If so, the AdBlue is no longer in the tank. Via the filter, through the lines, and — with any running — on to the high-pressure pump and each injector: that's how far it has gone.
Expect lumpy running, exhaust smoke, lost power, lights on your dash, or a stall — returning from Sylvia Avenue Open Space, perhaps, or midway across Carpenders Park. No starting it again to test: stop when safe, then turn everything off. Every start pulls more of it through.
Carpenders Park sits under 3 miles from the M1; if you were on it, leave by the next junction and stop safely instead of driving on.
How far it went matters. A few hundred yards across Carpenders Park to the car park by Grim's Ditch is a very different job from a run towards St Albans, under 10 miles away, with the AdBlue reaching further into the fuel system with each mile. Roughly how far had it come? Tell us.
Our technicians do all of the flushing where the vehicle has ended up, and once the engine has run there is more of it. Very seldom does it leave permanent damage when it is caught quickly.
Clearing AdBlue in a diesel around Carpenders Park: what it takes
Our technicians come to your car, wherever it has stopped in Carpenders Park: a side street close to Hatch End Cricket Club, a drive, a lay-by or a forecourt. Which fluid was put in, about how much, and if the motor has turned over: our technicians check first, because those decide the work.
Then the tank is emptied where the vehicle waits, and so the tainted fuel and the AdBlue come out together. Residue from AdBlue won't wash away unaided, and so the whole system gets a full flush, which counts far more here than with petrol. After that, your filter: flushed, or replaced when it has to be. Then fresh diesel, and then a check of your car. If your motor has not run, the majority of jobs take about half an hour once our engineers arrive. Low-noise enough to use outside a house at night, and fine on a busy forecourt, our pumps are explosion-proof.
Fresh diesel goes in to bleed the fuel system, and that is the final step. Whether it's a parking bay by the nearest station or a driveway in Carpenders Park, that is where we start it and you drive off. Our technicians make sure it runs correctly on fresh diesel before leaving. The whole job is done where the car is, so it never needs to be taken to a workshop. The insurer will want an engineer's report and your VAT invoice — both yours once this job is done.
