AdBlue in the Diesel Tank in Synwell? Keep It Switched Off
With AdBlue in your diesel tank, the ignition remains off and so does your engine. Urea mixed in water is what AdBlue is. The trouble begins once it's pulled through the lines — it won't ignite, and it won't blend with diesel. In Synwell, AdBlue in a diesel tank found before your motor runs normally comes down to a drain and a thorough flush, just where the vehicle is. Before anything, ring us on 0333 366 0103.
AdBlue in your diesel tank around Synwell: the first few minutes
Things to do:
- Keys out — then no one can switch anything on.
- Put the hazards on if you're at all near moving traffic.
- Which product, and roughly how much amount? Save the bottle or the till receipt, and our engineers can know.
- Our van finds you quickest with a postcode starting GL12 7, or simply the name of a street close by, and so call from the spot.
Things not to do:
- Do not start your motor, even for a moment to shift the vehicle.
- Do not switch the ignition on. On many diesels that alone runs the fuel pump.
- Adding more diesel doesn't help: AdBlue settles out rather than blending.
- Even a short stretch up Ragnall is too far to drive the vehicle.
- Beside the road, do not try draining it yourself.
At a forecourt around Synwell, whether it's the Shell or another one, ask the attendants to help you roll the vehicle clear of the petrol pump. On your own drive, do not move it at all.
AdBlue in a diesel tank: what it does
AdBlue is made for your exhaust, not your engine. From a separate tank it goes straight to your exhaust, cleaning what the motor lets out. Not one side suits the other: urea does not belong in a pump, and a pump cannot take urea.
It doesn't combine. After it's tipped into the tank, AdBlue acts nothing like diesel. Denser than diesel, it sinks and collects underneath it — the very place the intake draws from. Simplest of all: a vehicle that had AdBlue in Wortley overnight and has not been started since. The AdBlue sits at the foot of your tank, untouched — but it will be first through once your motor runs, before any diesel at all.
From there it causes two kinds of damage. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, so it keeps labouring on the parts it reaches for as long as it stays there. A motor left standing around Synwell with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Diesel protects the injection pump and every injector as it passes; water offers no lubrication, which is a separate kind of harm.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Fill a diesel with petrol by mistake over at the Gulf, and the problem is thinned fuel. Mixed through the diesel and sitting unused, it's harmless for now; running the engine is the damage.
The issue with AdBlue in a diesel is a totally wrong liquid. Since it doesn't burn, running it through isn't an option. Nor can it be thinned, since it splits back out — and the following fill will not clear away deposits or corrosion. So the flush matters for more here, and turning your key "to see", in the heart of Synwell or out in Bradley, does more harm than almost any other error.
The good news is the same as with petrol. Emptying a tank is the simplest job on any fuel system, and with no start-up, the AdBlue stays in there — anywhere around Gloucestershire your vehicle sits.
How does AdBlue end up in a diesel tank around Synwell?
After dark, two caps together — the AdBlue one and the diesel cap, occasionally under a single flap — can appear the same. No one intends it; plenty of layouts allow it. A bottle bought when heading home and poured in at home, rather than at the forecourt, is the typical route.
The ways it happens are few and familiar. Hurrying, outside The British School, after a warning lamp came on during the school run, a parent refills the car. A driver tips the container in at home, right off West View, as the day ends. One more pattern: darkness, the car park by The Falcon Steakhouse, and a driver opening that flap the first time.
It comes up most in a rental, a new motor, a company vehicle, or the spare vehicle in a family with both fuel types — the cars drivers use the least. Keep it switched off: that is the first step to the same mistake, wherever around Synwell or the remainder of Gloucestershire you happen to be.
AdBlue in your diesel tank in Synwell, and the engine started?
In that case, the AdBlue is no longer inside that tank. It's been sucked through the fuel filter and the lines, and if your motor ran for any time, it has got to your high-pressure pump and your injectors.
Maybe coming back from Synwell Playing Field, or part way across Synwell, your engine may go lumpy, smoke, lose power, flash the dash or stall. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. With each start, more of it is pulled through.
Leave the M5, under 5 miles from Synwell, by the next junction and park somewhere safe, not carrying on.
Distance matters: each mile pushes the AdBlue deeper into your system, and so driving towards Gloucester, under 25 miles away, gives a much bigger job than hopping across Synwell to the car park by Oliver Memorial Chapel, Synwell. Tell us about how far it had come.
Wherever the car came to a stop is where all of it gets done, even with more to flush after your engine has been run. Lasting damage is very unusual when it's caught soon.
Clearing AdBlue in a diesel around Synwell: what it takes
Wherever it has come to rest in Synwell — a filling station, a lay-by, a drive, a road beside Coombe Alpacas — the van travels to your car. Which fluid got in, roughly the quantity, plus if your motor has been run: our technicians ask before all else, because those shape the work.
Next, draining your tank on the spot removes the contaminated diesel and the AdBlue in one go. What remains from AdBlue will not wash out by itself, and so the whole system gets a careful flush, which matters much more with urea than for petrol. A test of the car comes at the end, once clean diesel is added and your filter gets flushed or, where necessary, swapped. The majority of these jobs are a half-hour visit once we turn up, provided the motor has not run. Low-noise enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.
Finally, your system is primed with fresh diesel. You set off as soon as we have fired it up, and it makes no difference whether the car is on a driveway around Synwell or in a bay by Cam & Dursley. Our engineers make sure it runs correctly on clean diesel before we leave. No workshop is needed at any point, with the entire job done on the spot. The insurer will want an engineer's report and the VAT invoice — both yours once this job is done.

AdBlue in a diesel tank around Synwell: the cost of fixing it
Every job is different, so no fixed price is honest. The cost shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that was put in. After that it turns on where your car is and whether a van can get to it safely, which is simpler on an open drive than in a tight space behind St Mary the Virgin.
Which fluid was put in, what quantity, plus if the engine ran: each Synwell call opens with exactly those, before a figure, never afterwards. Given those replies, a range shrinks to one firm number.
Before a van heads out, you are told the price on the phone. And you pay on the day, by card or by phone, with nothing upfront. Check your policy whilst we're on the way: many include misfuelling cover.
