Knights Enham: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has got into the diesel tank, keep your engine off and keep your ignition off. In plain terms, AdBlue is simply urea in water. The harm starts once it is pulled through the lines — it will not ignite, and it won't combine with diesel. A drain and a thorough flush, done where your car is in Knights Enham, is generally all AdBlue in a diesel tank takes — if it is caught before the motor has run. First, ring us on 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank in Knights Enham
Things to do:
- Take your keys out, and so nobody switches the ignition on.
- Close to moving traffic? So put the hazard lights on.
- Hold on to the receipt or the empty bottle, so you can tell us what got in and roughly how much.
- Tell us a postcode starting SP10 4, or whichever street lies closest, and the van finds you directly — so ring from wherever you are.
Don't:
- Moving the vehicle even a short way is no reason to fire up your motor.
- Turning the key to ignition by itself sets the pump going on plenty of diesels. Skip it.
- AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel will not weaken it.
- Even a short distance along Enham Lane is too far to drive it.
- Draining that tank on your own beside the road is not worth trying.
Moving the car away from the pumps is a job for attendants to help with, wherever Knights Enham forecourt you're on, the Tesco included. If you're on your own drive, leave it precisely where it is.
What does AdBlue do in a diesel tank?
Not the engine but the exhaust is where AdBlue belongs. Kept in a dedicated tank, it's injected into the exhaust stream to clean the fumes. Nothing in an injection pump is made for this liquid — and no part of that was meant to travel that way.
Inside a diesel tank it acts really differently from fuel. It doesn't mix in. Heavier than diesel, it sinks and pools underneath it — the same place the intake draws from. Simplest of all: a vehicle that had AdBlue in Foxcotte last night and has not been started since. The liquid sits at the base of the tank, undrawn — but it will be the first thing through once your motor runs, ahead of any diesel at all.
Two kinds of damage follow from there. Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filter elements and narrow channels; meanwhile, since it attacks certain metals, every part it reaches suffers for as long as it remains inside. A vehicle left standing around Knights Enham with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Then there's the water: it brings no protection to the components that need it the most — the high-pressure pump and every injector.
Petrol or AdBlue in a diesel: why AdBlue is frequently worse
Fill a diesel with petrol by mistake over at the BP, and the problem is diluted fuel. Damage just comes from driving on it. Mixed into the diesel and left in your tank, it does none.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. Not burning, it can't simply be run through. Nor can it be watered down, because it separates again — and the following fill won't clear away crystals or corrosion. So the flush counts more with AdBlue, and turning the key "to see", in the heart of Knights Enham or out in Smannell, does more harm than almost any other slip.
With AdBlue, the good news is no distinct from petrol. If your engine has not run, the AdBlue is still in that tank, and the tank is the easiest part of a fuel system to clear, wherever around Hampshire the vehicle is standing.
How does AdBlue end up in a diesel tank around Knights Enham?
Many cars put the AdBlue cap alongside the diesel cap, occasionally under a single flap, and after dark the two may appear the same. Nobody intends it. Most of the time it takes place with a bottle bought on the way home and poured in on the drive, not at the forecourt.
The ways it takes place are few and familiar. Hurrying, outside Roman Way Primary School, after a warning lamp came on during the school run, someone refills your car. A bottle is poured in at the end of the day on a drive just off Saxon Way. Otherwise, after dark outside The Merlin, the vehicle is topped up by a driver using that flap for the first time.
It comes up most in a rental, a brand-new vehicle, a company motor, or the other car in a family with one of each fuels — the vehicles drivers know least. An identical slip, same first response — leave it switched off — wherever you are around Knights Enham or the remainder of Hampshire.
Already started the motor with AdBlue in your diesel tank in Knights Enham?
The AdBlue has left the tank, then. Through the filter, along the lines, and — with any running — on to the injection pump and every injector: that's how far it travels.
Maybe returning from Bilgrove Copse, or midway across Knights Enham, your engine may run rough, smoke, lose pace, flash the dash or stall. No restarting to check: stop once safe, then turn everything off. Each start pulls more of it through.
Leave the M3, under 15 miles from Knights Enham, at the next junction and park safely, not carrying on.
How far it went matters. A couple of hundred yards across Knights Enham to the car park by Saint Michael and All Angels is a very different job from a run towards Winchester, under 15 miles away, with the AdBlue reaching further into the system with every mile. Roughly how far had it come? Tell us.
There's more to rinse out once the motor has been run, and we do all of it where the vehicle has stopped. Very seldom does it leave long-term damage when it is spotted early.
What emptying AdBlue from a diesel involves in Knights Enham
We come to your car, wherever it has stopped around Knights Enham: a side street near Poppy Park Memorial, a drive, a lay-by or a forecourt. Three answers decide the work, so first we ask which fluid was put in, roughly what quantity, and if your motor has run.
Right there, your tank is then drained, and all of the contaminated diesel and the urea come out as one. A careful flush matters much more with AdBlue than with petrol, because what remains will not wash away on its own. Testing the vehicle comes at the end, once clean diesel goes in and your filter is cleaned or, if necessary, swapped. The majority of these jobs are a half-hour visit once we get there, provided your engine has not run. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house at night.
Priming the system with fresh diesel comes last. Starting the car comes next, and then you set off from where your car is parked, by Andover or on a drive in Knights Enham. The check before our engineers leave is that it runs smoothly on clean diesel. Since the job is done in its entirety where the vehicle is, a garage never comes into it. The insurer is likely to want an engineer's report and the VAT invoice — each handed over once this job is done.

Knights Enham: what AdBlue in a diesel tank costs to fix
Since each callouts vary, a flat price wouldn't be honest. What shifts the cost is, firstly, whether the motor has been running and for how long; then how much AdBlue went in; and finally where the car is and whether our van can reach it safely, which is easier on an open driveway than in a tight gap behind St Paul Church Centre.
Which fluid was put in, how much, plus if it ran: every Knights Enham call opens by asking precisely those, before any quote, never after. Once they are answered, a range becomes a single firm number.
You get that quote by phone, before anyone sets off, and you pay on the day, by card or over the phone, with nothing upfront. While our engineer is on the way, dig out your policy: plenty include misfuelling.
