Southdown: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in the diesel tank, your ignition remains off and so does the motor. Water with urea dissolved in it: that's AdBlue. As it is water-based, it won't burn and never combines with diesel; damage only comes once your pump begins pulling it. If the motor has not run yet, AdBlue in a diesel tank is normally emptied and carefully purged where the car stands around Southdown. No step comes before ringing 0333 366 0103.
Your next steps right now, Southdown: AdBlue in your diesel tank
Do:
- Remove the keys, which prevents someone switching the electrics on.
- Put the hazards on if you're anywhere near moving traffic.
- Hold on to the receipt or the empty bottle, and so you can tell us what was put in and about how much.
- Give us a postcode starting BA2 1, or whatever street lies nearest, and our van reaches you directly — so ring wherever you are.
Never:
- Not even for a second, and not to roll the car: the engine remains off.
- Switching the key to ignition by itself starts your pump going on many diesels. Skip it.
- No extra fuel added. The AdBlue won't mix, so it's pointless.
- Leave it where it is instead of driving it anywhere, even a short way along Mount View.
- By the road, do not attempt draining it on your own.
On a forecourt in Southdown, whether it's the Sainsbury's or another one, ask the attendants to help you roll the vehicle clear of the petrol pump. Stopped on your own driveway? Then it stays just where it is.
AdBlue in a diesel tank: what it does
AdBlue is made for your exhaust, not your engine. From a dedicated tank it is fed straight to the exhaust, treating what the motor lets out. Nothing in an injection pump is made for this liquid — and no part of that was intended to travel that way.
Poured in with your diesel, it keeps separate rather than mixing — quite different from fuel. It sinks, because it is heavier than diesel, and settles low where the intake takes its supply from. A car topped up on a driveway in South Twerton overnight and left unstarted counts as the simple one. Nothing has pulled the AdBlue up yet — but once the engine runs, that is what goes first, directly from the bottom of that tank.
Once it's drawn in, the harm takes two forms. What remains when the water goes is urea, which turns into crystals: they lodge in tiny channels and block filters. On top of that, it attacks certain metals in the fuel system, and keeps going till it is flushed out. Where the AdBlue is in the pipework, waiting overnight around Southdown leaves it worse. Inside that tank only, time costs nothing. The water in it causes damage of its own: the high-pressure pump and your injectors depend on diesel to lubricate them, and water offers them nothing.
Why is AdBlue in a diesel commonly the bigger issue?
A problem of thinned fuel is what you end up with from fuelling a diesel with petrol from the Gulf. No damage comes while it stays unused, blended into the diesel — only when your engine runs on it.
AdBlue in a diesel is an issue of the wrong substance altogether. Not burning, it can't just be run through. It does not stay mixed, and so it cannot be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than almost anywhere else, whether your car is in Rush Hill or the middle of Southdown.
With AdBlue, the good news is no different from petrol. Clearing a tank is the easiest job on a fuel system, and with no running, the AdBlue stays in it — anywhere around Somerset your car sits.
Southdown: how AdBlue ends up in a diesel tank
After dark, two caps together — the AdBlue one and the diesel one, now and then under a single flap — can appear the same. Nobody intends it; many designs invite it. A container picked up while driving home and tipped in outside the house, instead of at the forecourt, is the typical story.
Usually, it takes place in one of a couple of familiar ways. The top-up gets rushed outside Roundhill Primary School, after your dash flashed with a warning while the children were taken in. A bottle is poured in at the end of the day on a drive just off Wedmore Park. Or someone unfamiliar with that flap tops up the car after dark, stopped in the car park outside Trowbridge House.
It crops up most in a hire car, a new vehicle, a company motor, or the other car in a home with one of each fuels — the vehicles drivers use least. Wherever around Somerset, Southdown as well, the slip does not change, and neither does the first response: leave it off.
Started your engine with AdBlue in the diesel tank around Southdown?
Then the AdBlue has left your tank. Given any running time, it travels to the injection pump and every injector, having passed via your filter and lines.
Perhaps returning from Roundhill, or midway across Southdown, the motor might run rough, smoke, lose power, light up your dash or cut out. Stop when safe. Switch off. Keep it off instead of restarting it to check. Each start pulls more of it through.
Southdown sits under 10 miles from the M4; if you were on it, leave at the next junction and pull up somewhere safe instead of carrying on.
A quick hop across Southdown to the car park by St Barnabas is one matter; driving towards Bath, under 3 miles away, is something else, since every mile carries the AdBlue deeper in. So mileage counts. Let us know about how far it had come.
Once the engine has run, the flush includes more, and all of it is done where the car has come to a stop. Very seldom does it leave permanent damage if it's noticed soon.
What clearing AdBlue from a diesel involves around Southdown
The car remains put, whether that's a street beside Roundhill Centre, a driveway, a layby or a filling station around Southdown, and the van travels to it. Three replies decide the job, and so before anything else our technicians ask which fluid got in, roughly what quantity, and if the motor has turned over.
Then that tank is cleared where the car waits, so the polluted fuel and the AdBlue come out together. What remains from AdBlue will not wash out unaided, so the fuel system gets a careful flush, which counts much more here than with petrol. Clean diesel goes in after the fuel filter is flushed — or replaced, if it needs to be — and then your car is tested. Engine not run? Then count on about half an hour once we are there for most jobs. Explosion-proof pumps make a live forecourt sensible to work on, and they run quiet enough to spare the street at night.
The final step is to prime the system on clean diesel. Starting it comes next, and then you drive off from where your car is parked, outside Oldfield Park or on a drive in Southdown. Before we leave, our technicians confirm it's running properly with clean diesel in. Our engineers do it all wherever the vehicle has ended up, and it never has to be taken to a workshop. At the end, there is the paperwork for the insurer: a VAT invoice and a report from the engineer.

AdBlue drains across Southdown and Somerset
Our vans that answer AdBlue call-outs in Southdown also cover the places round it, Whiteway, Kingsway and The Oval among them, and most of Somerset beyond, across the BA postcode area. Guessing doesn't help by a border or somewhere tricky to pin down; phone and check.
No towing is needed. In Southdown, a residential suburb, a mobile service fits: the vehicle is emptied where it stands, be it on a driveway, a side street, a parking area or a filling station.
What does AdBlue in a diesel tank cost to sort out around Southdown?
Since the jobs vary, a flat figure would not be fair. What shifts the price is, firstly, whether your engine has been running and for how long; then how much AdBlue went in; and then where the car is and whether our van can get to it safely, which is simpler on an open driveway than in a tight gap behind Southdown Methodist Church.
For that reason, every enquiry from Southdown begins with the identical trio — what got in, what quantity, whether the engine ran — ahead of any quote. With those replies, the range shrinks to one fixed figure.
You hear that quote by phone, before anybody sets off, and you pay on the day, by card or by phone, with nothing upfront. While the van is on the way, check your policy: plenty cover misfuelling.
Southdown: still beside the car?
Then the most useful thing you can do is nothing to your car. Ignition off, engine off, keys out. Petrol in Diesel takes over the remainder, across Southdown or wherever within Somerset, once you phone 0333 366 0103 to say it's AdBlue, about how big an amount, and whether the engine ran.
