AdBlue in the Diesel Tank in Shepperton Green? Keep It Switched Off
With AdBlue in the diesel tank, the ignition remains off and so does the motor. Water with urea dissolved in it: that's AdBlue. It doesn't burn, it doesn't mix with diesel, and the harm it does starts when your fuel system pulls it in. In Shepperton Green, AdBlue in a diesel tank found before the engine runs usually means a drain and a thorough flush, right where the vehicle is. Ring 0333 366 0103 before you do anything else.
What to do right now, Shepperton Green: AdBlue in your diesel tank
Do:
- Keys out — that way nobody can switch anything on.
- Hazards on, if moving traffic is at all near.
- Which fluid, and roughly how much amount? Hang on to the bottle or the till receipt, and our engineers will know.
- Call right where you are. Quote a TW17 0 postcode or the nearest street sign, and nobody has to search for you.
Not to do:
- Moving your vehicle just a few yards is no reason to fire up the engine.
- Don't switch your ignition on. On many diesels that alone runs the fuel pump.
- Don't top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
- Any driving at all is best avoided, even a short way along Laleham Road.
- By the road, don't try emptying it on your own.
The staff working at any Shepperton Green filling station — the BP among them — will normally lend a hand rolling it clear if you ask. Parked on your own driveway? Then it stays exactly as it is.
What does AdBlue do in a diesel tank?
AdBlue is made for the exhaust, not your engine. Its own tank keeps it, and from there it is fed into the exhaust, and there it treats the gas. No part in an injection pump is designed for this fluid — and no part of it was intended to go through one.
Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It drops, because it is denser than diesel, and settles low where the intake takes its fuel from. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Chertsey Meads last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in.
Once it's sucked in, the harm comes in two forms. What is left when the water evaporates is urea, which forms crystals: they settle in narrow channels and block filters. On top of that, it eats at certain metals in a fuel system, and keeps going till it is flushed out. A motor left sitting in Shepperton Green with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Diesel protects the high-pressure pump and every injector as it flows; water offers none of that, which is a second kind of harm.
Petrol or AdBlue in a diesel: why AdBlue is often worse
A fault of thinned fuel is what you get from fuelling a diesel with petrol from the Esso. No harm is done as long as it stays put, blended into your diesel — only when the motor runs on it.
The issue with AdBlue in a diesel is a completely unsuitable substance. It can't simply be run through, because it doesn't burn. It doesn't stay mixed, so it cannot be weakened. 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 the vehicle is in Upper Halliford or the middle of Shepperton Green.
As with petrol, there is good news. Not run? Then the AdBlue sits just in your tank, the easiest bit of the whole system to clear, anywhere your car has come to rest in Surrey.
AdBlue in a diesel tank around Shepperton Green: how it ends up there
In dim light, two caps together — the AdBlue cap and the diesel one, occasionally under a single flap — can look the same. Nobody intends it; plenty of layouts allow it. Usually it's not the forecourt: a driver buys a bottle driving home and tips it in outside the house.
A few familiar ways account for the majority of them. A warning light comes on during the school run, and the top-up occurs in a hurry outside Saxon Primary School. A bottle is poured in at the end of the day on a drive just off Sheep Walk. Otherwise, after dark by Barley Mow, your car gets refilled by a driver using that flap the first time.
Hired motors, new vehicles, fleet cars, or the spare vehicle in a home with both fuels: the least known cars get it most. Wherever you're around Shepperton Green or the rest of Surrey, it is the same slip and the same first answer: leave the car off.
Already started the motor with AdBlue in your diesel tank around Shepperton Green?
If so, the AdBlue is no longer in your tank. With any running time, it goes on to the high-pressure pump and every injector, having passed through your filter and pipework.
Maybe coming back from Nutty Wood, or part way across Shepperton Green, the engine may go rough, smoke, drop pace, flash your dash or stall. No restarting to test: pull over once it is safe, then switch it off. With each start, more of that is pulled through.
On the M3, under a mile from Shepperton Green, the next junction is where to exit, and anywhere sensible is where to stop — not driving on.
Distance counts: every mile carries the AdBlue deeper into your system, and so heading towards Westminster, under 25 miles away, gives a much bigger job than hopping across Shepperton Green to the car park by RC Church of John Fisher. Tell us roughly how far it had come.
Once the motor has run, the flush covers more, and all of it is done where the car has ended up. When it is spotted early, lasting damage is very unusual.
Shepperton Green: how AdBlue is emptied from a diesel
A street by Shepperton Youth Centre, a driveway, a lay-by or a filling station: anywhere the car has stopped around Shepperton Green, our technicians come to it. The job rests on three answers, and our technicians ask for first — what got in, the amount, and if the engine has run.
Next, draining that tank right there removes the polluted diesel along with the AdBlue in one go. Your system is rinsed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. A test of your vehicle follows at the end, after clean diesel goes in and the fuel filter is flushed or, if necessary, swapped. Not run? In that case expect roughly half an hour on site for most jobs. Low-noise enough for use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.
Bleeding the fuel system with clean diesel comes at the end. After that our technicians fire it up and you drive off, whether from a parking space outside Shepperton or a driveway around Shepperton Green. The check before our technicians go is that it runs properly on fresh diesel. The entire job is done where the car is, so it never needs to go to a workshop. Your insurer will want an engineer's report and your VAT invoice — both yours afterwards.

AdBlue in a diesel tank around Shepperton Green: the cost of fixing it
Because the callouts differ, a flat price would not 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 got in. After that it depends on where the vehicle is and whether a technician can reach it safely, which is simpler on an open drive than in a tight spot behind Church of St Mary Magdalene.
