Sherston: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in the diesel tank, the ignition remains off and so does your motor. Urea mixed in water is what AdBlue is. As it is water-based, it will not ignite and never combines with diesel; damage just starts once your pump begins drawing it. If the motor hasn't run yet, AdBlue in a diesel tank is generally drained and carefully cleaned where the vehicle sits in Sherston. First, ring us on 0333 366 0103.
Your next steps straight away, Sherston: AdBlue in the diesel tank
Things to do:
- So no one can switch the ignition on, pull your keys out.
- If you're at all near moving traffic, put the hazard lights on.
- The empty bottle or the till receipt shows us the fluid and the amount, and so don't throw it away.
- Call just where you are. Say a SN16 0 postcode or the closest street sign, and nobody has to search for you.
Don't do these:
- Not even briefly, and not to shift the vehicle: the motor remains off.
- Your ignition remains off: on lots of diesels, turning it on is enough to run the pump.
- No extra fuel added. The AdBlue won't blend, and so it is wasted.
- Keep the car where it is instead of driving it anywhere, even a short distance up Noble Street.
- No emptying it yourself, at all, on the verge.
Get the people behind the counter to help you move the car away from the island if you are at a forecourt in Sherston, whether it is the BP or elsewhere. If you are on your own drive, leave the vehicle precisely where it stands.
What does AdBlue do in a diesel tank?
Not the engine but the exhaust is where AdBlue is meant to go. From a separate reservoir it goes straight to the exhaust, cleaning what your engine emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Poured in with your diesel, it stays apart rather than mixing — entirely unlike fuel. Denser than diesel, it sinks and pools below it — the same spot the pickup draws from. When your pump runs, the AdBlue is first to go through. Before then it sits underneath the diesel, and that is how a vehicle filled in Willesley yesterday and not started stays the straightforward one, as long as nobody turns the key.
Once it's pulled in, the damage comes in two forms. What remains when the water evaporates is urea, which turns into crystals: they lodge in tiny passages and block filters. On top of that, it eats at some metals in a fuel system, and keeps going until it's flushed out. Overnight, a vehicle parked in Sherston with AdBlue through its pipework gets worse; if it's only inside that tank, nothing changes. Diesel protects the injection pump and each injector as it flows; water offers no lubrication, which is a separate kind of damage.
AdBlue in a diesel: why it's often worse than petrol
Fill a diesel with petrol by mistake over at the another forecourt nearby, and this problem is thinned fuel. No harm is done while it sits put, blended into the diesel — only once your engine works on it.
With AdBlue in a diesel, the liquid as such is simply the wrong one. It can't just be run through, because it doesn't burn. Deposits and corrosion stay through the next fill, and AdBlue separates again out of the diesel, so thinning it won't help. That is why the flush matters more, and trying the engine "to see" does more harm here than almost any other slip — in Luckington or the centre of Sherston equally.
The good news is the same as with petrol. Wherever across Wiltshire your car has stopped, an unrun engine means the AdBlue still in the reservoir: the simplest bit of a fuel system to clear.
Sherston: how AdBlue ends up in a diesel tank
After dark, two caps together — the AdBlue one and the diesel cap, occasionally under a single flap — may appear the same. No one intends it; many layouts invite it. Most of the time it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
Usually, it takes place in one of a couple of familiar ways. The top-up is rushed outside Sherston CofE Primary School, after the dash flashed with a warning while the kids were dropped off. In the evening, a container is tipped in on a driveway close to Court Street. Or a driver unfamiliar with that flap refills the car after dark, parked in the car park outside Rattlebone Inn.
Rented vehicles, new motors, fleet vehicles, or the spare vehicle in a family with one of each: the least known cars see it the most. An identical slip, an identical first response — keep it switched off — anywhere you happen to be around Sherston or the remainder of Wiltshire.
Started your engine with AdBlue in your diesel tank in Sherston?
The AdBlue has left that tank, then. It has been sucked through your filter and the lines, and if the motor ran for any time, it has got to your high-pressure pump and the fuel injectors.
Maybe returning from Old Wood, or part way across Sherston, the engine might run lumpy, smoke, lose pace, flash your dash or stall. No starting it again to test: stop when it is safe, then switch everything off. Each start pulls more of it through.
Leave the M4, under 5 miles from Sherston, at the first junction and park somewhere safe, not driving on.
A quick hop across Sherston to the car park by Holy Cross Memorial Lych Gate is one matter; heading towards Bath, under 15 miles away, is another, because each mile carries the AdBlue deeper in. So mileage counts. Let us know roughly how far it had come.
Wherever your car came to a stop is where all of it gets done, even with more to clean out after the engine has been run. Very rarely does it leave lasting damage when it is noticed soon.
Draining AdBlue in a diesel in Sherston: what it takes
A street by Holy Cross, a drive, a lay-by or a filling station: wherever your car has come to rest around Sherston, our engineers come to it. What got in, roughly how much, and if the engine has turned over: we ask before all else, because those shape the work.
Then your tank is emptied where the car sits, and so the contaminated fuel and the AdBlue come out together. What remains from AdBlue will not wash away unaided, so the fuel system gets a careful flush, which matters far more with urea than for petrol. A test of the car follows at the end, once fresh diesel goes in and the filter is cleaned or, where needed, swapped. Roughly half an hour once we arrive is typical for most jobs when your engine hasn't run. Explosion-proof pumps make a busy forecourt safe to work on, and they run quiet enough not to disturb the street at night.
Finally, the system is bled with clean diesel. You drive off as soon as our engineers have started it, and it makes no difference whether your car is on a driveway in Sherston or in a bay by Chippenham. Before leaving, our engineers make sure it's running smoothly with new diesel in. The entire job is done where the car is, so it never has to be taken to a garage. At the end, there is paperwork for the insurer: a VAT invoice plus a written report from the engineer.
About Sherston, for a moment
Sherston is a village in Wiltshire, situated on the banks of a river at an elevation of around 118 metres. Sherston lies near the town of Easton and the smaller settlements of Sherston Parva and Sopworth, and is approximately 14.5 miles from the city of Bath. Sherston has a population of around 1394 people, predominantly living in detached houses. Sherston is also within commuting distance of London, being around 89.7 miles to the west of the capital.
Sherston and Wiltshire: AdBlue drains across the area
AdBlue jobs in Sherston are passed to vans that serve the towns near it — Easton Town, Sherston Parva plus Sopworth — and most of Wiltshire further out, throughout SN postcodes. Close to a border, or somewhere tricky to pin down? Asking is better than assuming, and so ring.
A van that comes to you suits Sherston, a village: there's no need to bring the car to us, since our engineers drain it there, in a drive, a side street, a parking area or a filling station.
What AdBlue in a diesel tank costs to put right in Sherston
Every job differs, and so not one single quote is fair. Three things shift the cost: whether the engine has been running and for how long, how much AdBlue got in, and where the vehicle is. That last one turns on whether our van can reach it safely, and an open drive is simpler than a tight spot behind Congregational Church.
That's why each call from Sherston starts with the same three questions, asked before giving a figure, not after: what went in, how much, and if it's run. The replies turn a range into a straight price.
Our quote is given on the call, before a van leaves; settling up comes on the day, by card or over the phone, and nothing upfront. While the van is travelling, dig out your insurance: plenty include misfuelling.
In Sherston and still next to the car?
Then the most handy thing you can do is nothing to the vehicle. Motor off, keys out, ignition off. Call 0333 366 0103 and tell us it is AdBlue, roughly how much, and whether it's run. Petrol in Diesel takes it from there, in Sherston or anywhere across Wiltshire.
