AdBlue in the Diesel Tank in Twyford? Keep It Switched Off
Motor off, ignition off: that is how you start if AdBlue has gone into your diesel tank. AdBlue is urea mixed in water. As it is water-based, it will not ignite and never combines with diesel; trouble just starts once the pump begins drawing it. A drain and a thorough flush, done where the car is around Twyford, is generally what AdBlue in a diesel tank takes — if it is caught before the motor has been run. Ring 0333 366 0103 before you do anything else.
Those opening minutes: AdBlue in the diesel tank around Twyford
To do:
- Keys out — then no one can switch anything on.
- Near moving traffic? So put the hazard lights on.
- Which product, and about how much amount? Hang on to the bottle or the till receipt, and our technicians will see.
- Ring us from where you are. A postcode starting RG10 9, or the name of the nearest street, gets our van to you without a search.
Things not to do:
- Not even briefly, and not to shift the vehicle: your motor stays off.
- Don't switch your ignition on. On plenty of diesels that alone runs the fuel pump.
- AdBlue does not dilute in diesel — it separates out — so adding extra fuel will not weaken it.
- Do not drive it anywhere, not even a short way up Old Bath Road.
- No emptying it yourself, at all, at the verge.
At a forecourt in Twyford, whether it's the BP or another one, ask the attendants to help you push the car away from the pump. If you are on your own drive, leave the car just where it is.
AdBlue in a diesel tank, and what it does there
Not your motor but your exhaust is where AdBlue belongs. From a dedicated reservoir it is fed directly to the exhaust, cleaning what your engine lets out. Not one side fits the other: urea doesn't belong in a pump, and an injection pump cannot deal with urea.
Fuel blends; AdBlue, once tipped in, will not. Its behaviour is not at all like fuel's. It drops, since it's heavier than diesel, and settles low where the intake draws its fuel from. When your system runs, the AdBlue is top of the list to be pulled through. Before then it sits beneath your diesel, which is why a car topped up in Borough Marsh yesterday and not started remains the simple one, provided nobody turns the key.
It does two kinds of harm from there. What remains once the water goes is urea, which forms crystals: they lodge in narrow passages and clog filters. Worse, it eats at certain metals in the fuel system, and keeps going until it's cleared out. Lines holding AdBlue mean damage overnight for a car sitting in Twyford. Just in your tank, it stays stable. The water in it causes harm of its own: the high-pressure pump and the injectors depend on diesel to lubricate them, and water offers them nothing.
Why is AdBlue in a diesel frequently the bigger problem?
Put petrol in a diesel at the Texaco and you have an issue of thin fuel. It mixes with your diesel, and while it's inside that tank it does no damage; the damage comes from running the motor on it.
With AdBlue in a diesel, the fluid as such is simply the wrong one. Not burning, it cannot simply be run through. It doesn't stay mixed, so it cannot be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your motor "to see" costs more here than almost anywhere else, whether your car is in Hurst or the middle of Twyford.
The good news is the same as with petrol. Wherever in Berkshire your vehicle has come to rest, an unrun motor leaves the AdBlue yet inside the reservoir: the simplest part of a fuel system to empty.
How does AdBlue end up in a diesel tank in Twyford?
It's not deliberate. Many vehicles keep the AdBlue cap beside the diesel inlet, occasionally under one flap, and muddling them up is easy in poor light. A container picked up while driving home and tipped in outside the house, instead of at the filling station, is the usual route.
The ways it occurs are few and familiar. Halfway through the morning drop-off, the dashboard warns, and outside Polehampton Church of England Infant School the refill is rushed. A driver pours the container in at home, right off Church Street, as the day ends. Or a driver unfamiliar with that flap refills the car in dim light, stopped in the car park outside Duke of Wellington.
It takes place most in the motors motorists know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol. Wherever you are around Twyford or the rest of Berkshire, it is the same error and the same first answer: leave it off.
AdBlue in the diesel tank around Twyford, and the motor started?
Then the tank is no longer where the AdBlue is. With any running time, it goes on to the high-pressure pump and each injector, after passing via your filter and pipework.
Perhaps returning from Loddon Nature Reserve, or midway across Twyford, your engine might run lumpy, smoke, lose power, light up your dash or stall. No starting it again to check: stop when it is safe, then switch everything off. More of it is pulled through with each start.
If you were on the A329(M), under 3 miles from Twyford, come off at the next exit and stop somewhere safe rather than pressing on.
How far it went counts. A few hundred yards across Twyford to the car park by United Reformed Church is a very different job from a run towards Oxford, under 50 miles away, with the AdBlue reaching further into your system with each mile. Roughly how far had it come? Tell us.
Our engineers do all of the cleaning where the car has stopped, and once the motor has been started there is more of it. Very rarely does it leave permanent damage if it is spotted quickly.
What draining AdBlue from a diesel involves in Twyford
Anywhere it has come to rest in Twyford — a filling station, a layby, a driveway, a road beside Twyford Library — the van comes to the car. The work depends on three replies, which our technicians get first — which fluid was put in, the quantity, and whether the engine has run.
Then that tank is cleared where the vehicle stands, so the contaminated fuel and the AdBlue come out together. What remains from AdBlue won't flush away unaided, so the whole system gets a careful flush, which matters far more here than with petrol. After that, the filter: flushed, or replaced if it must be. Then fresh diesel, and then a test of your car. Most of these jobs are a half-hour job once we arrive, if the engine hasn't run. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house at night.
The final step is to prime the system on clean diesel. You drive off as soon as our technicians have started the car, and it makes no difference whether your car is on a drive in Twyford or in a bay by the nearest station. Before leaving, we make sure it is running smoothly with fresh diesel in. The entire job is done where the vehicle is, so it never has to go to a workshop. At the end, you are given paperwork for your insurer: a VAT invoice plus a report from the engineer.

What does AdBlue in a diesel tank cost to sort out around Twyford?
There is no honest single quote, since the jobs aren't the same. Three things shift the cost: whether your engine has been running and for how long, how much AdBlue went in, and where the car is. That last one turns on whether a van can get to it safely, and an open driveway is easier than a tight gap behind Twyford Parish Church.
Which fluid got in, how much, and whether it ran: each Twyford call begins by asking precisely that, ahead of a figure, never after. Their answers shrink the range right down to a single figure.
You get that quote on the phone, before anybody sets off, and you pay on the day, by card or over the phone, with nothing upfront. Check your insurance while we are on the way: plenty carry misfuelling cover.
