Goldsithney: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that is where you begin if AdBlue has got into your diesel tank. Chemically, AdBlue is just urea in water. Being water-based, it won't burn and won't blend with diesel; damage just comes when your pump starts drawing it. In Goldsithney, AdBlue in a diesel tank found before your engine runs normally means a drain and a thorough flush, just where your car is. Nothing comes before calling 0333 366 0103.
Your next steps straight away, Goldsithney: AdBlue in the diesel tank
To do:
- Pocket your keys, and that prevents someone turning the power on.
- If you're anywhere close to moving traffic, put the hazard lights on.
- The empty bottle or the receipt tells us the fluid and the amount, and so don't throw it out.
- Ring us from where you are. A postcode starting TR20 9, or the name of the nearest street, gets our van to you without a search.
Don't do these:
- Not even briefly, and not to shift your vehicle: the engine stays off.
- Plenty of diesels run their pump the instant your ignition goes on, and so leave the car off.
- Pouring in extra diesel doesn't work: AdBlue settles out rather than blending.
- Never drive the car anywhere, not even a short distance up Primrose Hill.
- Do not try to drain the car yourself by the kerbside.
On a forecourt around Goldsithney, whether it's the JET or another one, ask the staff to help you roll the car away from the pump. At home, the car remains just as it was left.
AdBlue in a diesel tank: what it does
Not your motor but your exhaust is where AdBlue belongs. Its own reservoir holds it, and from there it's sprayed into the exhaust, and there it treats the gas. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.
Fuel blends; AdBlue, after tipped in, will not. Its behaviour is not at all like fuel's. The intake sucks fuel from the lowest part of that tank, and that's just where AdBlue settles: being heavier than diesel, it sinks. Simplest of all: one that got AdBlue in St Hilary overnight and has not turned since. The liquid sits at the foot of the tank, undrawn — though it will be first through once your engine runs, ahead of any diesel at all.
It causes two kinds of harm from there. What is left once the water goes is urea, which forms crystals: they lodge in tiny passages and clog filters. Worse, it eats at certain metals in the fuel system, and keeps going till it's cleared out. Pipes holding AdBlue mean damage overnight for a vehicle sitting in Goldsithney. Just in the tank, it stays the same. Then there's the water: it offers no protection to the parts that need it the most — the high-pressure pump and every injector.
Why is AdBlue in a diesel frequently the bigger problem?
Petrol put into a diesel on Texaco's forecourt leaves your fuel thin — that's the whole issue. No damage is done as long as it sits put, mixed into your diesel — only once your motor runs on it.
AdBlue in a diesel is a problem of the wrong substance altogether. It cannot just be run through, since it does not burn. 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 motor "to see" costs more here than nearly anywhere else, whether the car is in Tregurtha Downs or the middle of Goldsithney.
The same good news applies as with petrol. Never started? Then the AdBlue sits only in that tank, the easiest bit of the entire system to empty, wherever the vehicle has come to rest around Cornwall.
Goldsithney: how AdBlue ends up in a diesel tank
No one means to do it. The AdBlue filler on many motors waits right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.
Usually, it happens in one of a couple of familiar ways. Halfway through the morning drop-off, the dashboard flags it up, and outside St Hilary School the top-up is rushed. Near Retallack Gardens, someone tips a bottle in on that drive in the evening. Else, in dim light by The Crown Inn, your vehicle gets refilled by someone using that flap for the first time.
It takes place most in the cars people know least: a hire car, a new vehicle, a company car, or the second car of a household with one diesel and one petrol. An identical mistake, same first step — leave it off — anywhere you are in Goldsithney or the remainder of Cornwall.
AdBlue in the diesel tank in Goldsithney, and the motor started?
Then the tank is no longer where the AdBlue is. Through the filter, along the pipework, and — given any running time — into the high-pressure pump and each injector: that is how far it has gone.
Watch for rough running, exhaust smoke, falling power, lights on the dash, or a cut-out — coming back from Trevarthian Wood, say, or midway across Goldsithney. No restarting to check: stop once it is safe, then switch everything off. With each start, more of it is pulled through.
Goldsithney lies over 50 miles from the M5; if you were on it, leave at the first junction and pull up somewhere safe rather than carrying on.
Each mile pushes the AdBlue deeper into the system. That's why a hop across Goldsithney to park beside Goldsithney Methodist Church and a drive of under 25 miles for Truro are such distinct jobs. Approximately how far had it come? Tell us.
Once your engine has run, the flush covers more, and all of it is done where the vehicle has stopped. If it's noticed quickly, lasting damage is very uncommon.
Emptying AdBlue in a diesel in Goldsithney: what it takes
Our technicians come to the vehicle, wherever it has stopped around Goldsithney: a side street near St Pirans Hall, a drive, a lay-by or a forecourt. The job rests on three replies, which we get before all else — which fluid got in, the amount, and if the engine has turned over.
The polluted diesel and the urea come out together when the tank is drained, right there. Residue from AdBlue will not wash out unaided, so the whole system gets a careful flush, which counts far more with urea than with petrol. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If your motor has not run, most jobs take about half an hour once we are there. Quiet enough for use outside a house at night, and fine on a working forecourt, our pumps are explosion-proof.
The last step is to bleed the fuel system on clean diesel. Firing it up comes next, and then you set off from where your car is parked, outside St Erth or on a driveway around Goldsithney. Our technicians make sure it runs smoothly on new diesel before we go. Because the job is done in full where the vehicle is, a garage never comes into it. Insurers want a VAT invoice and an engineer report, and both come afterwards.

Goldsithney: what AdBlue in a diesel tank costs to fix
Every job is different, and so no single quote would be fair. Whether the motor has been running, and for how long, comes first in what shifts the cost. How much AdBlue got in comes next, and then the location of your car, because an open drive is easier for a van to reach safely than a tight spot behind St Hilary.
Which fluid was put in, what quantity, plus if it ran: every Goldsithney call opens with exactly those, ahead of any quote, not after. Once they are answered, a range turns into one fixed number.
The quote is given during the call, before a van leaves; settling up comes on the day, by card or by phone, with nothing upfront. Check your insurance whilst we're on the way: many include misfuelling cover.
