AdBlue in the Diesel Tank in Arborfield Cross? Keep It Switched Off
Engine off, ignition off: that is how you begin if AdBlue has got into the diesel tank. Urea mixed in water is what AdBlue is. It does not burn, it does not mix with diesel, and the harm it does begins when the fuel system draws it in. If your engine hasn't run yet, AdBlue in a diesel tank is usually drained and carefully rinsed where your car stands around Arborfield Cross. Phone 0333 366 0103 before you do anything else.
What to do right now, Arborfield Cross: AdBlue in the diesel tank
Do:
- So nobody can turn the ignition on, take your keys out.
- If you're at all close to moving traffic, put the hazards on.
- So you can tell us which fluid it was and about what quantity, save your receipt or the empty bottle.
- The van locates you quickest with a postcode starting RG2 9, or simply the name of a street nearby, and so call from the spot.
Never do these:
- Don't start your motor, even for a moment to move the vehicle.
- Plenty of diesels run their pump the instant your ignition comes on, so leave the vehicle off.
- Pouring in extra diesel doesn't work: AdBlue separates out rather than thinning.
- Even a short way up Brant Close is too far to drive the vehicle.
- No emptying it yourself, at all, at the roadside.
On a forecourt in Arborfield Cross, whether it's the Esso or another one, ask the staff to help you push the car clear of the pump. Parked on your own drive? Then it remains just where it is.
What does AdBlue do in a diesel tank?
AdBlue is made for your exhaust, not the motor. Its own reservoir holds it, and from there it's sprayed into the exhaust, where it treats the gas. No part inside an injection pump is designed for this fluid — and no part of it was meant to travel that way.
It doesn't blend. After it is poured into the tank, AdBlue acts nothing like diesel. Denser than diesel, it drops and pools underneath it — the same place the pickup draws from. When your pump runs, the AdBlue is top of the list to go through. Until then it waits beneath your diesel, which is why a car filled in Barkham yesterday and not switched on stays the simple one, provided nobody touches your key.
From there it does two kinds of harm. 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, and so it keeps running on the parts it hits for as long as it remains there. A vehicle left standing in Arborfield Cross with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Then there's the water: it brings no lubrication to the parts that need it most — the injection pump and every injector.
Petrol or AdBlue in a diesel: why AdBlue is regularly worse
Put petrol in a diesel at the Asda and you have an issue of thin fuel. No damage is done while it stays unused, blended into your diesel — only when your engine runs on it.
The trouble with AdBlue in a diesel is a totally unsuitable substance. It does not burn, and so it can't just be run through. Nor can it be thinned, because it separates back out — and the following tankful won't rinse away crystals or corrosion. So the flush counts for more here, and turning the key "to see", in the centre of Arborfield Cross or out in Farley Hill, does more harm than almost any other mistake.
The same good news holds as with petrol. If your motor has not run, the AdBlue is still in that tank, and the tank is the easiest part of a fuel system to clear, wherever across Berkshire the vehicle is standing.
AdBlue in a diesel tank in Arborfield Cross: how it ends up there
It's not on purpose. Many vehicles keep the AdBlue cap alongside the diesel one, occasionally behind a single flap, and mixing them up is simple after dark. Mostly it is not the filling station: someone picks up a container heading home and tips it in outside the house.
The ways it occurs are few and familiar. The top-up is rushed outside The Coombes Church of England Primary School, after the dash flashed with a warning while the kids were dropped in. Near Melrose Gardens, someone tips a container in on that drive in the evening. Otherwise, in dim light by The Bull Inn, your car is refilled by someone opening that flap the first time.
Hired vehicles, brand-new motors, fleet motors, or the spare car in a family with both fuels: the least familiar cars get it the most. Wherever across Berkshire, Arborfield Cross included, the slip does not change, and nor does the first response: keep it off.
AdBlue in your diesel tank around Arborfield Cross, and your engine started?
Then your tank is no longer where the AdBlue is. Given any running time, it travels to the injection pump and every injector, after passing through your filter and lines.
Expect rough running, smoke, lost power, warnings on your dash, or a cut-out — coming back from Arborfield Park, say, or midway across Arborfield Cross. Once you safely can, pull over then switch it off — without turning it on again to see. More of it is pulled through with each start.
Arborfield Cross lies under 3 miles from the M4; if you were on it, exit by 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 Arborfield Cross to park beside Arborfield Village Hall and a drive of under 50 miles for Oxford are such separate jobs. Roughly how far had it come? Tell us.
There is more to clean out once your engine has run, and we do all of it where the car has come to a stop. If it's spotted early, lasting damage is very uncommon.
What clearing AdBlue from a diesel involves around Arborfield Cross
The vehicle remains put, whether that is a street near Royal Observer Corps, a driveway, a layby or a forecourt in Arborfield Cross, and the van comes to it. The job rests on three replies, which we get first — which fluid got in, the quantity, and if your motor has turned over.
Right there, that tank is then drained, and both the contaminated diesel and the urea come out as one. With AdBlue, more so than with petrol, the flush counts: the whole system is flushed right through because residue will not wash out by itself. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Engine not run? In that case count on roughly half an hour on site for most jobs. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house at night.
The last step is to bleed the fuel system on clean diesel. Firing it up comes next, and then you head off from where the vehicle is parked, outside Winnersh or on a drive in Arborfield Cross. Before we leave, our technicians make sure it's running properly with clean diesel in. The entire job is done where the car is, so it never has to go to a garage. Your insurer will want an engineer's report and the VAT invoice — both yours afterwards.

What AdBlue in a diesel tank costs to put right in Arborfield Cross
No flat price would be honest, because every job is different. What changes the price is, first, whether the motor has been running and for how long; then how much AdBlue was put in; and after that where the vehicle is and whether a van can get to it safely, which is easier on an open driveway than in a tight gap behind Saint Bartholomew's.
That is why every call from Arborfield Cross starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it has run. Those answers narrow the range down to a single figure.
