Peppard Hill: AdBlue in the Diesel Tank? Leave It Off
AdBlue in the diesel tank? Then keep your motor off — and your ignition as well. AdBlue is urea mixed in water. Unlike fuel, it neither burns nor mixes, and no harm happens till your engine sucks it round. If your motor has not run yet, AdBlue in a diesel tank is normally emptied and carefully rinsed where your car stands around Peppard Hill. Before you do anything else, ring 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank in Peppard Hill
To do:
- Take the keys out, so nobody switches the ignition on.
- Put the hazards on if you are at all near moving traffic.
- The empty bottle or your receipt shows us the fluid and the quantity, and so do not throw it away.
- Tell us a postcode starting RG9 5, or whichever street is closest, and the van finds you directly — so ring from wherever you stand.
Things not to do:
- Shifting the vehicle just a few yards is no reason to start the engine.
- The ignition stays off: on many diesels, switching it on is enough to run your fuel pump.
- Adding more diesel does not work: AdBlue separates out instead of blending.
- Even a short stretch along Colmore Lane is too far to drive the vehicle.
- Emptying your tank yourself by the road is not one to try.
Get the people behind the counter to help you roll your car off the pumps if you are on a forecourt in Peppard Hill, whether it is the the nearest petrol station or somewhere else. At home, the vehicle remains exactly as it was left.
AdBlue in a diesel tank, and what it does there
Not your motor but the exhaust is where AdBlue is meant to go. Its own reservoir keeps it, and from there it is sprayed into your exhaust, where it treats the fumes. A fuel pump is not made to take it, and AdBlue was never supposed to travel through one.
It doesn't blend. Once it's tipped into a tank of diesel, AdBlue behaves nothing like fuel. The pickup takes fuel from the lowest part of your tank, and that's precisely where AdBlue ends up: as it is heavier than diesel, it sinks. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Sonning Common last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.
From there it does 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, and so it keeps working on the parts it reaches for as long as it remains there. By daybreak, a car parked in Peppard Hill with AdBlue through its pipework gets worse; where it's only inside your tank, it doesn't. Diesel lubricates the high-pressure pump and every injector as it flows; water gives none of that, and that is a separate form of harm.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Petrol put into a diesel on Stoke Row Garage's forecourt leaves the fuel thin — that is the main fault. It mixes with the diesel, and while it's in that tank it does no harm; the damage comes from running the motor on it.
The issue with AdBlue in a diesel is a completely unsuitable substance. It can't just be run through, because it doesn't burn. Whether your car is in Shepherds Green or the centre of Peppard Hill, turning it over "to see" costs more in this case than almost any other mistake, and the flush counts for more. The reasons: it will not stay blended, so watering it down fails; and deposits and corrosion survive the following fill.
As with petrol, there's good news. Anywhere in Oxfordshire your vehicle has stopped, an unstarted engine means the AdBlue still in the tank: the easiest part of any fuel system to clear.
AdBlue in a diesel tank in Peppard Hill: how it ends up there
In dim light, two caps together — the AdBlue cap and the diesel one, occasionally under one flap — may look the same. No one intends it; plenty of layouts allow it. Most of the time it occurs with a bottle bought on the way home and poured in on the driveway, not at the pump.
It tends to take place in a few familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside Peppard Church of England Primary School. A driver tips the container in outside their house, right off Colliers Lane, as the day ends. Or a driver new to that flap tops up the car in dim light, stopped in the car park by The Unicorn.
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. Wherever around Oxfordshire, Peppard Hill as well, the slip doesn't change, and nor does the first response: keep it off.
Already started the engine with AdBlue in the diesel tank in Peppard Hill?
The AdBlue has left the tank, then. The filter and pipework have had it sucked along, and any running carries it on to the high-pressure pump and every injector.
You may notice your motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Spring Wood or halfway across Peppard Hill. No restarting to check: pull over once safe, then turn it off. More of that is pulled through with each start.
If you were on the M4, under 10 miles from Peppard Hill, come off at the next junction and stop somewhere sensible instead of pressing on.
Every mile pushes the AdBlue deeper in. That's why crossing Peppard Hill to park near Springwater Church and a drive of under 25 miles towards Oxford are such distinct jobs. About how far it had come is worth telling us.
We do all of the cleaning where the vehicle has come to a stop, and once your engine has been started there is more of it. Lasting damage is very rare when it is spotted soon.
Emptying AdBlue in a diesel around Peppard Hill: what it takes
A road beside Catholic Church of Saint Michael, a driveway, a layby or a forecourt: anywhere the vehicle has come to rest around Peppard Hill, our technicians come to it. Before anything else our engineers ask what went in, about how much, and if the engine has been run, since those answers determine the work.
On the spot, the tank is then drained, and both the polluted diesel and the urea come out at once. With AdBlue, more so than with petrol, flushing counts: the whole system is cleaned all the way through since what remains will not wash out unaided. After that, the fuel filter: cleaned, or replaced when it has to be. Then clean diesel, then a test of the car. If your motor hasn't run, most jobs take about half an hour once our engineers arrive. Our pumping gear is explosion-proof, so a live forecourt is no fault, and it is hushed enough for a residential street late at night.
Clean diesel goes in to bleed the fuel system, and that's the final step. You head off as soon as our engineers have started it, and it makes no difference whether the vehicle is on a drive in Peppard Hill or in a bay outside Henley-On-Thames. The check before we head off is that it runs correctly on clean diesel. The entire job is done where your car is, so it never has to be taken to a workshop. You get a VAT invoice and an engineer report later, which is what insurers want.

AdBlue in a diesel tank in Peppard Hill: the cost of fixing it
Each job is different, so not one single price is honest. The price moves first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where the car is and whether a van can get to it safely, which is simpler on an open drive than in a tight gap behind The Church of Christ the King.
That's why each call from Peppard Hill starts with the same three queries, asked before giving a figure, not after: what went in, how much, and whether it's run. Those answers turn a range into a straight quote.
Before anyone heads out, you hear the quote by phone. Then payment is on the day, by card or by phone, with nothing in advance. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
