AdBlue in the Diesel Tank in Bishops Tachbrook? Keep It Switched Off
AdBlue in your diesel tank? Then keep the engine off — and the ignition too. Urea dissolved in water is all AdBlue is. The harm begins once it is sucked through your pump — it will not ignite, and it will not combine with diesel. In Bishops Tachbrook, AdBlue in a diesel tank found before your motor runs usually comes down to a drain and a thorough flush, just where the car is. Before you do anything else, call 0333 366 0103.
AdBlue in the diesel tank in Bishops Tachbrook: the first few minutes
Do:
- So nobody can turn your ignition on, pull your keys away.
- If you are at all near moving traffic, put the hazards on.
- So you can give us which fluid it was and about what quantity, save the receipt or the empty bottle.
- Tell us a postcode starting CV33 9, or whichever street is closest, and the van reaches you straight — so call from wherever you stand.
Not to do:
- Don't start the engine, even for a moment to move the car.
- The ignition stays off: on many diesels, switching it on is enough to start the fuel pump.
- Pouring in more diesel doesn't work: AdBlue separates out rather than thinning.
- Any driving at all is best avoided, even a short distance down Church Hill.
- Do not try to drain the car yourself at the roadside.
Rolling your car away from the pumps is a job for attendants to help with, whichever Bishops Tachbrook forecourt you're on, the Asda included. If you're on your own drive, leave the car exactly where it sits.
AdBlue in a diesel tank: what it does
Not the engine but the exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into the exhaust gas to clean it. Not one side suits the other: urea does not belong in a pump, and an injection pump cannot take urea.
It does not blend. Once it's tipped into a tank of diesel, AdBlue behaves nothing like diesel. Denser than diesel, it sinks and collects underneath it — the very place the pickup draws from. The first thing the system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Myton last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.
Two kinds of harm follow from there. Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filters and tiny channels; and, because it eats at some metals, each part it reaches keeps suffering for as long as it stays inside. Overnight, a car sitting in Bishops Tachbrook with AdBlue through its pipework grows worse; if it is only inside the tank, it doesn't. And there's the water: it offers no protection to the parts that need it the most — the high-pressure pump and every injector.
AdBlue in a diesel: why it's often worse than petrol
Fill a diesel with petrol in error over at the Sainsbury's, and the problem is diluted fuel. No harm comes while it sits put, blended into your diesel — only once your engine works on it.
AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all. It can't just be run through, because it doesn't burn. Crystals and corrosion stay through the following tankful, and AdBlue separates again out of the diesel, so thinning it won't help. That is why the flush matters so much, and trying your engine "to see" costs more with AdBlue than almost any other slip — in Sydenham or the centre of Bishops Tachbrook equally.
With AdBlue, the good news is no different from petrol. Emptying a tank is the simplest job on a fuel system, and with no start-up, the AdBlue stays in it — anywhere across Warwickshire your vehicle has stopped.
How AdBlue ends up in a diesel tank in Bishops Tachbrook
Many vehicles place the AdBlue cap alongside the diesel one, occasionally behind one flap, and in dim light the two can appear identical. Nobody intends it. It mostly takes place outside the house, from a bottle bought on the journey home, not at the filling station.
Mostly, it takes place in one of a few familiar ways. Hurrying, outside Bishops Tachbrook CofE Primary School, after a warning light came on during the school run, someone tops up the car. A driver pours the container in at home, just off Mallory Road, as the day ends. Else, after dark by The Leopard, your car is refilled by a driver opening that flap the first time.
It happens most in the motors drivers know least: a hire car, a new car, a company car, or the second car of a household with one diesel and one petrol. Wherever around Warwickshire, Bishops Tachbrook included, the slip doesn't change, and nor does the first response: keep it off.
AdBlue in your diesel tank around Bishops Tachbrook, and your engine started?
In that case, the AdBlue is no longer in the tank. Your filter and pipework have had it pulled through, and some running takes it on to the high-pressure pump and each injector.
Lumpy running, smoke, lost power, dashboard lights or stalling: any might show up, maybe midway across Bishops Tachbrook or coming back from Tachbrook Country Park. Pull over when safe. Turn off. Leave the vehicle off instead of testing it again. With each start, more of that is pulled through.
Exit the M40, under a mile from Bishops Tachbrook, at the next junction and park somewhere safe, rather than carrying on.
Mileage matters: every mile pushes the AdBlue further into your system, and so driving towards Coventry, under 15 miles away, gives a much bigger job than hopping across Bishops Tachbrook to the car park by St Chad. Let us know about how far it had come.
Wherever the vehicle came to a stop is where all of it gets done, even with more to rinse out after the engine has been started. If it's noticed quickly, permanent damage is very rare.
What clearing AdBlue from a diesel involves around Bishops Tachbrook
Our engineers come to the vehicle, wherever it has stopped around Bishops Tachbrook: a side street near Mike Morris, a drive, a lay-by or a forecourt. Before anything else our technicians ask what was put in, about how much, and if the motor has run, since those answers decide this work.
On the spot, that tank is then drained, and all of the polluted diesel and the urea come out as one. What remains from AdBlue won't wash away unaided, and so the fuel system gets a careful flush, which counts far more with urea than with petrol. After that, your filter: flushed, or replaced when it must be. Then clean diesel, and then a check of your car. If your engine has not run, the majority of jobs take about half an hour once we are there. The equipment is explosion-proof, so a live filling station is no problem, and it is quiet enough for a residential street late at night.
Fresh diesel goes in to bleed your system, and that's the last step. Whether it's a parking space at Leamington Spa or a driveway around Bishops Tachbrook, that is where our technicians start it and you drive off. It's checked on fresh diesel to be sure it runs correctly before we leave. No workshop is needed at any stage, with the whole job done then and there. Your insurer is likely to want an engineer's report and your VAT invoice — each handed over once the job is done.

AdBlue in a diesel tank in Bishops Tachbrook: the cost of fixing it
Every job differs, and so not one fixed quote would be fair. The price shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it rests on where your car is and whether a van can reach it safely, which is simpler on an open drive than in a tight spot behind Ted Kevin Ellard.
With that reason, each call from Bishops Tachbrook opens with the identical trio — what was put in, what quantity, if the engine ran — before any quote. Those answers turn a range into a straight price.
