AdBlue in a Diesel Tank in Hemingford Grey? Don't Start It
If AdBlue has gone into your diesel tank, leave your engine off then leave your ignition off. Urea mixed in water is all AdBlue is. Not like fuel, it neither burns nor mixes, and no harm happens till the engine pulls it round. A drain and a thorough flush, done where your car is in Hemingford Grey, is usually what AdBlue in a diesel tank takes — if it is caught before the motor has run. Before you do anything else, ring 0333 366 0103.
AdBlue in your diesel tank in Hemingford Grey: the first few minutes
Do:
- Pocket the keys, and that prevents anyone switching the power on.
- Hazards on, if moving traffic is anywhere near.
- So you can give us which fluid it was and about how much, save your receipt or the empty bottle.
- Give us a postcode starting PE28 9, or whatever street lies closest, and our van finds you directly — so ring from wherever you are.
Not to do:
- No starting your motor — not briefly, not to shift the car.
- Turning your key to ignition by itself starts your pump going on plenty of diesels. Skip it.
- Adding more diesel does not work: AdBlue separates out rather than blending.
- Any driving at all is to be avoided, including a short way up Rosenthal Terrace.
- No emptying it yourself, either, at the roadside.
Ask the people behind the counter to help you move your car away from the pumps if you're at a forecourt around Hemingford Grey, whether it is the Texaco or somewhere else. On your own driveway, do not move it at all.
AdBlue in a diesel tank, and what it does there
The engine isn't what AdBlue is made for; your exhaust is. Kept in a separate tank, it's squirted into the exhaust stream to clean the gases. No part inside an injection pump is made for this liquid — and no part of it was meant to travel that way.
Fuel mixes; AdBlue, after tipped in, won't. Its behaviour is nothing like fuel's. The intake takes fuel from the lowest part of your tank, and that's precisely where AdBlue settles: being denser than diesel, it sinks. A car topped up on a drive in Wyton yesterday evening and not started since is the straightforward one. No pump has sucked the AdBlue up so far — though once the motor runs, that is what is pulled first, directly from the bottom of your tank.
From there it does two kinds of damage. Crystals and corrosion. As the water dries, it strands urea that hardens in filter elements and tiny channels; and, since it eats at certain metals, every part it reaches keeps suffering for as long as it remains inside. A motor left sitting in Hemingford Grey with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Then there is the water: it brings no lubrication to the parts that need it most — the high-pressure pump and every injector.
Why is AdBlue in a diesel commonly the bigger issue?
Petrol pumped into a diesel on another forecourt nearby's forecourt makes the fuel watery — that's the whole issue. It mixes with the diesel, and whilst it's in your tank it causes no harm; the harm comes from running your engine on it.
AdBlue in a diesel is a fault of the wrong substance altogether. It cannot just be run through, because it doesn't burn. Deposits and corrosion stay through the next tankful, and AdBlue separates back out of your diesel, so watering it can't help. Hence the flush matters more, and turning the key "to see" does more harm here than almost any other mistake — in Fenstanton or the centre of Hemingford Grey equally.
As with petrol, there's good news. Never started? Then the AdBlue waits only inside that tank, the easiest bit of the entire system to clear, wherever your vehicle has stopped across Cambridgeshire.
How AdBlue ends up in a diesel tank around Hemingford Grey
Many motors place the AdBlue cap alongside the diesel one, now and then behind one flap, and after dark the two can appear the same. No one means it. Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
A couple of familiar ways cover the majority of them. Midway through the drop-off, the dashboard warns, and outside Hemingford Grey Primary School the top-up is rushed. Close to Church Street, someone tips a container in at home in the evening. One more version: dim light, a pub car park outside The Cock, and someone using that flap the first time.
Hired vehicles, brand-new motors, company motors, or the spare vehicle in a home with both fuels: the least known cars see it the most. An identical slip, same first response — keep it off — wherever you are in Hemingford Grey or the rest of Cambridgeshire.
Hemingford Grey: started your engine with AdBlue in the diesel tank?
Then the tank is no longer where the AdBlue is. Given any running, it travels to the high-pressure pump and every injector, after passing through your filter and lines.
You may notice your motor running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Daintree rec or halfway across Hemingford Grey. Pull over when it is safe. Turn off. Keep the car off rather than restarting it to check. With each start, more of that is pulled through.
Hemingford Grey lies under 10 miles from the A1(M); if you were on it, leave at the next junction and stop somewhere safe rather than driving on.
Mileage matters: each mile carries the AdBlue deeper in, and so heading towards Cambridge, under 15 miles away, makes a far bigger job than crossing Hemingford Grey to the car park by St James. Roughly how far it had come is worth telling us.
Our technicians do all of the cleaning where your car has come to a stop, and once the motor has run there is more of it. Permanent damage is very rare when it's spotted soon.
What does an AdBlue drain on a diesel involve in Hemingford Grey?
The car remains put, whether that's a street beside Hemingford Pavilion, a drive, a lay-by or a forecourt in Hemingford Grey, and the van travels to it. The work depends on three replies, which our technicians ask for first — what got in, the quantity, and if your motor has turned over.
The polluted diesel and the urea leave as one when your tank is drained, right there. Residue from AdBlue won't flush away unaided, and so the whole system gets a careful flush, which matters much more with urea than for petrol. Testing your car comes last, once clean diesel is added and the fuel filter is flushed or, where necessary, swapped. If your motor has not run, most jobs take about half an hour once we are there. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.
Fresh diesel goes in to bleed your system, and that is the final step. After that our technicians start it and you drive off, whether from a parking bay at Huntingdon or a driveway in Hemingford Grey. Our technicians make sure it runs smoothly on new diesel before we go. No workshop is required at any point, with the whole job done then and there. Insurers want a VAT invoice and an engineer report, and you get both at the end.

AdBlue in a diesel tank around Hemingford Grey: the cost of fixing it
Since the callouts vary, a single price would not be honest. Whether your engine has run, and for how long, comes first in what shifts the price. How much AdBlue was put in comes next, and then the location of the vehicle, since an open driveway is simpler for our van to reach safely than a tight space behind Liquid Skillz.
