Don't Start It: AdBlue in a Diesel Tank in Bengeo
AdBlue in the diesel tank? Then leave the engine off — and your ignition as well. Urea dissolved in water is all AdBlue is. The trouble begins once it's sucked through the lines — it will not burn, and it will not blend with diesel. If your engine has not run yet, AdBlue in a diesel tank is generally drained and thoroughly flushed where the car sits in Bengeo. Before you do anything else, ring 0333 366 0103.
What to do right now, Bengeo: AdBlue in the diesel tank
To do:
- Take the keys out, so no one switches your ignition on.
- Put the hazard lights on if you're anywhere close to moving traffic.
- The empty bottle or your receipt tells us the product and the quantity, and so don't throw it away.
- Call us from where you are. A postcode starting SG14 3, or the name of the closest street, brings the van to you without a search.
Things not to do:
- Not even briefly, and not to shift your vehicle: your motor stays off.
- Your ignition stays off: on lots of diesels, switching it on is enough to run your fuel pump.
- Don't top up with diesel to dilute it. AdBlue doesn't dilute in diesel; it separates out.
- Keep the vehicle where it is instead of driving it anywhere, even a short way down Gosselin Road.
- No emptying it yourself, either, at the verge.
Rolling the car off the island is a job for attendants to help with, wherever Bengeo forecourt you're on, the Esso or any other. On your own driveway, do not touch it at all.
AdBlue in a diesel tank, and what it does there
Not your motor but the exhaust is where AdBlue is meant to go. Its own tank holds it, and from there it is fed into your exhaust, where it treats the fumes. Neither side suits the other: urea doesn't belong in an injection pump, and a pump cannot deal with urea.
Fuel mixes; AdBlue, once tipped in, won't. The behaviour is not at all like fuel's. It drops, because it is heavier than diesel, and settles down where the pickup draws its supply from. When the system runs, the AdBlue is top of the list to go through. Before then it waits beneath the diesel, and that is how a vehicle topped up in Waterford yesterday and never started stays the straightforward case, provided no one touches the key.
Once it is sucked in, the damage comes in two forms. It attacks some metals found in fuel systems, working on whatever it touches till it's cleared completely. And when the water goes, the urea forms crystals that clog filters and lodge in narrow passages. A motor left standing around Bengeo with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. The water in it causes harm of its own: the high-pressure fuel pump and your injectors depend on diesel to lubricate them, and water gives them nothing.
Petrol or AdBlue in a diesel: why AdBlue is frequently worse
Top up a diesel with petrol by mistake over at the BP, and the issue is thinned fuel. Harm just comes from driving on it. Mixed into the diesel and sitting inside your tank, it causes nothing.
The issue with AdBlue in a diesel is a totally unsuitable liquid. It can't just be run through, since it doesn't burn. It doesn't stay mixed, and so it cannot be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than nearly anywhere else, whether your car is in Pine Hurst or the middle of Bengeo.
With AdBlue, the good news is no separate from petrol. Not started? Then the AdBlue sits only inside the tank, the easiest bit of the whole system to empty, wherever your vehicle has come to rest around Hertfordshire.
How does AdBlue end up in a diesel tank around Bengeo?
It is not on purpose. Plenty of vehicles have the AdBlue cap beside the diesel one, occasionally under one flap, and mixing them up is easy in poor light. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the pump.
Usually, it occurs in one of a couple of familiar ways. A warning light comes on during the school run, and the top-up occurs in a hurry outside Bengeo Primary School. Near Duncombe Close, a driver pours a container in on that drive in the evening. Or your car is topped up in the car park at The White Lion, in poor light, by someone who has never opened that flap before.
The least familiar vehicles see it most — rentals, brand-new ones, company ones, and the spare car of a home with one of each fuels. An identical slip, same first response — keep it switched off — wherever you happen to be in Bengeo or the rest of Hertfordshire.
Already started your engine with AdBlue in your diesel tank in Bengeo?
In that case, the AdBlue is no longer in that tank. Given any running time, it travels to the injection pump and every injector, having passed via your filter and lines.
Maybe returning from Bengeo Recreation Ground, or part way across Bengeo, the engine might go lumpy, smoke, lose pace, light up your dash or stall. When you safely can, pull over and turn it off — without restarting to test. Each start pulls more of that through.
Exit the A1(M), under 10 miles from Bengeo, at the next junction and park safely, not driving on.
Every mile carries the AdBlue further into the system. That's why crossing Bengeo to park beside Bengeo Parish Church Hall and a drive of under 15 miles towards St Albans are such distinct jobs. Let us know about how far it had come.
Wherever your car came to a halt is where all of it gets done, even with more to flush after your engine has been running. Noticed quickly, it very seldom leaves permanent damage.
Bengeo: how AdBlue is emptied from a diesel
The car stays put, whether that's a road beside Holy Trinity Bengeo, a drive, a lay-by or a forecourt around Bengeo, and our van travels to it. Three answers decide the job, and so first our technicians ask which fluid was put in, about the amount, plus if your motor has turned over.
Then the tank is cleared where the vehicle stands, and so the tainted fuel and the AdBlue come out together. A full flush matters far more with AdBlue than with petrol, since what remains will not clear away by itself. Clean diesel goes in after the filter is cleaned — or replaced, if it needs to be — and then your vehicle is tested. Roughly half an hour on site is typical for most jobs when your motor hasn't run. Explosion-proof pumps mean a live forecourt safe to work on, and they run quiet enough to spare the street at night.
Clean diesel goes in to prime your system, and that's the last step. Whether it is a parking space at Hertford East or a driveway in Bengeo, that is where our engineers fire it up and you set off. We confirm it runs smoothly on new diesel before we go. No garage is required at any point, with the whole job done then and there. Insurers want a VAT invoice and an engineer report, and both come afterwards.

Bengeo and Hertfordshire: AdBlue drains across the area

No towing is needed. In Bengeo, a residential suburb, a mobile service works: your vehicle is drained on the spot, whether in a drive, a side street, a car park or a filling station.
Bengeo: what AdBlue in a diesel tank costs to fix
Every job differs, so no fixed price would be fair. What moves the cost is, first of all, whether your engine has been running and for how long; then how much AdBlue got in; and finally where the car is and whether a technician can reach it safely, which is simpler on an open drive than in a tight gap behind Saint Leonard's Church.
For that in mind, each enquiry from Bengeo begins by asking the same trio — which fluid got in, how much, whether it ran — before any quote. Those replies shrink the range down to one figure.
Before a van sets off, you are told our quote on the phone. Then you pay on the day, card or over the phone, with nothing in advance. Misfuelling cover is part of plenty of insurance policies, so it pays to look at yours before the van gets there.
