Higher Bojewyan: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in your diesel tank, your ignition stays off and so does the motor. Urea dissolved in water is what AdBlue is. Unlike fuel, it neither ignites nor blends, and no harm starts till your motor pulls it through. If the engine has not run yet, AdBlue in a diesel tank is usually emptied and carefully cleaned where the car stands around Higher Bojewyan. Call 0333 366 0103 before you do anything else.
What to do straight away, Higher Bojewyan: AdBlue in the diesel tank
To do:
- So no one can switch your ignition on, take the keys away.
- If you are at all near moving traffic, put the hazard lights on.
- So you can tell us which liquid it was and roughly what quantity, save the till receipt or the empty bottle.
- Ring right where you are. Quote a TR19 7 postcode or the nearest street sign, and nobody has to hunt for you.
Do not do these:
- Do not start your motor, even for a moment to move your car.
- Many diesels run their fuel pump the moment your ignition comes on, and so leave it off.
- Adding more diesel does not work: AdBlue separates out instead of thinning.
- Even a short way along Ponds Hill is too far to drive it.
- Do not try to drain the car yourself by the kerbside.
Moving the vehicle away from the island is a job for staff to help with, wherever Higher Bojewyan forecourt you are on, the Trewellard Garage or any other. On your own driveway, don't touch it at all.
What does AdBlue do in a diesel tank?
Not your motor but the exhaust is where AdBlue belongs. It goes into its own tank and is sprayed into your exhaust gas to clean it. Not one side suits the other: urea does not belong in an injection pump, and a pump can't deal with urea.
It doesn't combine. Once it's poured into a tank of diesel, AdBlue acts not at all like diesel. Heavier than diesel, it drops and pools below it — the very spot the intake sucks from. Once your system runs, the AdBlue is top of the list to go through. Until then it sits beneath the diesel, and that is how a vehicle filled in Morvah yesterday and not switched on stays the simple one, provided nobody touches the key.
Two kinds of harm come from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps labouring on the components it reaches for as long as it remains there. Overnight, a car sitting around Higher Bojewyan with AdBlue through its pipework grows worse; if it's just in your tank, it doesn't. And there's the water: it brings no lubrication to the components that rely on it most — the injection pump and every injector.
Why is AdBlue in a diesel regularly the bigger problem?
Petrol put into a diesel on another forecourt nearby's forecourt makes your fuel thin — that is the main issue. No damage comes as long as it sits unused, mixed into your diesel — only once the engine works on it.
AdBlue in a diesel is a problem of the wrong substance altogether. Not burning, it cannot simply be run through. It doesn't stay mixed, so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether the car is in Lower Boscaswell or the middle of Higher Bojewyan.
As with petrol, there is good news. Emptying a tank is the simplest part on any fuel system, and with no running, the AdBlue remains in there — anywhere across Cornwall the vehicle sits.
AdBlue in a diesel tank around Higher Bojewyan: how it ends up there
After dark, two caps together — the AdBlue one and the diesel cap, now and then under a single flap — can look the same. Nobody intends it; plenty of layouts invite it. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.
A couple of familiar ways account for most cases. The refill is rushed outside Pendeen School, after the dash lit up with a warning as the kids were dropped in. Near B3306, a driver tips a container in on the drive after work. Another pattern: dim light, a pub car park by The North Inn, and someone opening that flap for the first time.
Rented cars, brand-new motors, company cars, or the spare vehicle in a home with one of each: the least familiar vehicles see it the most. Keep it off: that is the first response to the same mistake, wherever in Higher Bojewyan or the rest of Cornwall you are.
AdBlue in the diesel tank around Higher Bojewyan, and your engine started?
The AdBlue has left the tank, then. Given any running, it goes on to the injection pump and every injector, after passing through the filter and lines.
Watch for lumpy running, exhaust smoke, falling power, lights on your dash, or a cut-out — returning from Borlaze Park, perhaps, or part way across Higher Bojewyan. Pull over when safe. Switch off. Keep the car off instead of restarting it to check. Each start pulls more of it through.
On the M5, over 50 miles from Higher Bojewyan, the first junction is where to exit, and anywhere sensible is where to park — not carrying on.
Every mile carries the AdBlue further into your system. That is why a hop across Higher Bojewyan to park beside Yew Tree Gallery and a drive of under 50 miles for Truro are very separate jobs. About how far it had come is worth telling us.
Our technicians do all of the cleaning where your car has stopped, and once your engine has been started there is more of it. Noticed quickly, it very seldom leaves long-term damage.
Higher Bojewyan: how AdBlue is emptied from a diesel
We come to your car, wherever it has stopped around Higher Bojewyan: a side street near Engine House, a drive, a lay-by or a forecourt. The job depends on three answers, which our technicians ask for first — which fluid was put in, the quantity, and if your motor has run.
Then that tank is emptied where your car stands, so the polluted fuel and the AdBlue come out together. What remains from AdBlue won't wash out by itself, and so the whole system gets a full flush, which counts far more here than with petrol. Next, your filter: flushed, or replaced when it must be. After that fresh diesel, and then a check of the car. The majority of these jobs are a half-hour job once we turn up, if the motor hasn't run. Low-noise enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.
Bleeding the system with clean diesel comes last. You set off as soon as we have fired it up, and it makes no difference whether the vehicle is on a driveway in Higher Bojewyan or in a bay at Penzance. Before we leave, our technicians confirm it's running smoothly with new diesel in. The whole job is done where your car is, so it never needs to go to a garage. Insurers ask for a VAT invoice and an engineer report, and you get both at the end.

What does AdBlue in a diesel tank cost to sort out around Higher Bojewyan?
Since the jobs vary, a single figure would not be fair. The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where your car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight spot behind Chimney.
Before a figure, never after, every call from Higher Bojewyan begins with the same three questions: the fuel, the quantity, plus if it ran. When they are answered, a range becomes a single fixed number.
