Derriford: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that's where you begin if AdBlue has got into your diesel tank. In plain terms, AdBlue is simply urea in water. The harm begins once it is sucked through the pump — it won't burn, and it won't blend with diesel. Caught before the motor has been run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the car is around Derriford. Before you do anything else, ring 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank in Derriford
Do:
- Keys out — then no one can power anything on.
- Near moving traffic? So put the hazard lights on.
- Keep the till receipt or the empty bottle, and so you can tell us what went in and about how much.
- Call right where you are. Say a PL6 8 postcode or the nearest street sign, and nobody has to search for you.
Don't do these:
- Don't start your motor, even for a moment to move the car.
- Turning the key to ignition by itself sets the pump running on plenty of diesels. Skip it.
- No more fuel added. The AdBlue won't blend, so it's pointless.
- Even a short stretch down Derriford Road is too far to drive the car.
- Do not try to drain the car yourself at the kerbside.
On a forecourt around Derriford, whether it is the Texaco or another one, ask the attendants to help you roll your car clear of the pump. At home, your car stays exactly as it was left.
AdBlue in a diesel tank: what it does
AdBlue is made for the exhaust, not your engine. Its own reservoir keeps it, and from there it's sprayed into your exhaust, where it cleans the fumes. Nothing in a fuel pump is designed for this fluid — and none of that was meant to travel through one.
Poured in with the diesel, it stays separate rather than mixing — quite different from fuel. The intake sucks fuel from the deepest part of your tank, and that's just where AdBlue settles: being denser than diesel, it sinks. A motor filled on a driveway in Estover yesterday evening and not started since counts as the simple case. No pump has pulled the AdBlue up yet — but when the motor turns, that is what is pulled first, directly from the bottom of your tank.
From there it causes two kinds of damage. Crystals and corrosion. As the water dries, it strands urea that crystallises in filters and narrow passages; meanwhile, since it eats at certain metals, every part it touches keeps suffering for as long as it stays inside. A car left standing around Derriford with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Then there is the water: it brings no protection to the parts that need it the most — the high-pressure pump and each injector.
AdBlue in a diesel: why it's regularly worse than petrol
Fill a diesel with petrol by mistake over at the Asda, and the issue is diluted fuel. Blended into the diesel and left still, it is harmless for now; running the engine does the damage.
The issue with AdBlue in a diesel is a completely wrong liquid. It can't just be run through, since it doesn't burn. Crystals and corrosion remain through the next tankful, and AdBlue splits back from your diesel, and so thinning it won't work. That is why the flush counts so much, and trying the engine "to see" costs more with AdBlue than almost any other mistake — in Woolwell or the centre of Derriford equally.
As with petrol, there's good news. Wherever in Devon your vehicle has come to rest, an unstarted engine means the AdBlue still inside the tank: the simplest bit of a fuel system to clear.
How does AdBlue end up in a diesel tank in Derriford?
Nobody means to do it. The AdBlue filler on many motors rests right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. A bottle bought when heading home and tipped in at home, rather than at the filling station, is the typical story.
It tends to occur in a few familiar ways. Halfway through the morning drop-off, the dashboard flags it up, and outside St Matthew's Church of England Primary and Nursery Academy the top-up is hurried. A bottle is poured in at the end of the day on a drive just off Plymbridge Lane. Another version: dim light, the car park outside The Jack Rabbit, and a driver using that flap the first time.
It crops up the most in a hire car, a new car, a fleet motor, or the other motor in a home with both fuel types — the cars people know least. Wherever you are around Derriford or the rest of Devon, it's the same error and the same first answer: leave the vehicle off.
Started your engine with AdBlue in your diesel tank around Derriford?
Then the tank is no longer where the AdBlue is. The fuel filter and pipework have had it pulled along, and some running takes it on to the injection pump and every injector.
Maybe coming back from Bircham Valley, or midway across Derriford, the engine may run rough, smoke, drop pace, flash your dash or stall. No restarting to check: stop once safe, then turn it off. With each start, more of it is pulled through.
Derriford lies under 50 miles from the M5; if you were on it, exit by the next junction and pull up safely instead of driving on.
Distance matters: every mile carries the AdBlue further in, and so heading towards Plymouth, under 5 miles away, makes a much larger job than hopping across Derriford to the car park by University Sports Centre. Roughly how far had it come? Tell us.
Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out after the engine has been running. Noticed quickly, it very seldom leaves long-term damage.
Draining AdBlue in a diesel in Derriford: what it takes
A street by Derriford Church, a driveway, a lay-by or a forecourt: anywhere the car has stopped in Derriford, our technicians come to it. Before anything else our technicians ask what went in, about how much, and whether the motor has been run, since those replies decide the work.
On the spot, that tank is then drained, and all of the polluted diesel and the urea leave as one. A careful flush matters far more after AdBlue than after petrol, because what remains won't wash away by itself. Next, the filter: cleaned, or replaced when it must be. After that fresh diesel, then a check of the car. Most of these jobs are a half-hour visit once we turn up, if your motor hasn't run. Low-noise enough for use outside a house at night, and safe on a busy forecourt, our pumps are explosion-proof.
Last, the fuel system is primed with new diesel. You drive off as soon as our technicians have started it, and it makes no difference whether the car is on a driveway in Derriford or in a space at Plymouth. The check before our technicians leave is that it runs correctly on clean diesel. Our technicians do it all wherever the vehicle has ended up, and it never needs to go to a garage. Insurers want a VAT invoice and an engineer report, and both come at the end.

Derriford and Devon: AdBlue drains across the area
AdBlue call-outs around Derriford go to teams that cover the towns around it — Glenholt, Southway plus Crownhill — and most of Devon beyond, across PL postcodes. Guessing doesn't help by a county line or anywhere hard to pin down; ring and check.

What AdBlue in a diesel tank costs to put right around Derriford
Since the jobs vary, a single price wouldn't be fair. The cost changes first with how long, if at all, your engine has been running, and next with the amount 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 driveway than in a tight space behind Derriford Health & Leisure Centre.
That is why each call from Derriford starts with the same three questions, asked before giving a figure, not after: what got in, how much, and if it's run. With them, a range shrinks to one firm number.
Before a van heads out, you are told our price on the phone. And payment is on the day, card or over the phone, with nothing in advance. While the van is on the way, check your insurance: plenty cover misfuelling.
