Don't Start It: AdBlue in a Diesel Tank in Caversham Heights
Engine off, ignition off: that's where you begin if AdBlue has gone into the diesel tank. AdBlue is urea mixed in water. It doesn't burn, it doesn't mix with diesel, and the harm it does starts when the system draws it in. In Caversham Heights, AdBlue in a diesel tank found before the engine runs usually means a drain and a thorough flush, just where your car is. Ring 0333 366 0103 before you do anything else.
What to do right now, Caversham Heights: AdBlue in the diesel tank
Things to do:
- Remove the keys, which prevents someone switching the power on.
- Hazards on, if moving traffic is at all close.
- Hold on to your receipt or the empty bottle, and so you can tell us what got in and roughly how much.
- The van finds you quickest with a postcode starting RG4 7, or simply the name of a street nearby, so phone from the car.
Not to do:
- Moving your vehicle just a short way is no reason to start the engine.
- Turning the key to ignition alone starts your pump going on many diesels. Skip it.
- AdBlue does not dilute in diesel — it separates out — so adding extra diesel will not weaken it.
- Keep the car where it is instead of driving it anywhere, even a short distance along Highmoor Road.
- Beside the road, do not attempt emptying it yourself.
Ask the people behind the counter to help you move the car away from the pumps if you are on a forecourt around Caversham Heights, whether it is the Esso or somewhere else. Stopped on your own driveway? Then it stays just where it is.
AdBlue in a diesel tank: what it does
Meant for the exhaust, AdBlue has no place in your engine. It goes into its own tank and is sprayed into the exhaust gas to clean it. Neither side suits the other: urea does not belong in an injection pump, and an injection pump cannot deal with urea.
Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It is heavier than diesel, so it sinks and gathers at the bottom of the tank, which is where the pickup draws fuel from. The first thing the system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Emmer Green last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.
After it is pulled in, the harm takes two forms. Crystals and corrosion. As the water dries, it strands urea that crystallises in filters and narrow channels; meanwhile, because it attacks certain metals, each part it reaches keeps suffering for as long as it remains in there. Lines carrying AdBlue spell harm by morning for a vehicle parked around Caversham Heights. Just inside your tank, it stays the same. Water lubricates nothing. The injection pump and each injector need diesel flowing past them, and so the water content harms them in its own right.
Petrol or AdBlue in a diesel: why AdBlue is commonly worse
Top up a diesel with petrol by mistake at the BP, and this issue is thinned fuel. Damage just comes from driving on it. Mixed into the diesel and left inside that tank, it does nothing.
AdBlue in a diesel is a problem of the wrong substance altogether. Because it does not burn, running it through is not an option. Whether the car is in Tokers Green or the centre of Caversham Heights, firing it up "to see" costs more with AdBlue than nearly any other slip, and the flush counts more. The reasons: it will not remain mixed, and so diluting it fails; and crystals and corrosion outlast the next tankful.
As with petrol, there is good news. Clearing a tank is the easiest part on any fuel system, and with no start-up, the AdBlue stays in there — wherever around Berkshire the car has stopped.
Caversham Heights: how AdBlue ends up in a diesel tank
It is not on purpose. Many cars keep the AdBlue inlet beside the diesel one, now and then under one flap, and muddling them up is simple in poor light. It mostly happens at home, from a container bought on the journey home, not at the filling station.
The ways it takes place are few and familiar. Hurrying, outside Caversham Primary School, after a warning lamp came on during the school run, a parent refills the vehicle. Near Albert Road, a driver tips a container in at home in the evening. Another version: dim light, a pub car park by The Griffin, and someone opening that flap the first time.
Hired motors, new vehicles, company vehicles, or the spare vehicle in a home with both fuels: the least familiar cars see it the most. Wherever you're in Caversham Heights or the remainder of Berkshire, it's the same mistake and the same first answer: leave the vehicle off.
AdBlue in your diesel tank in Caversham Heights, and your engine started?
In that case, the AdBlue is no longer inside the tank. The filter and lines have had it pulled along, and any running time carries it on to the injection pump and every injector.
Perhaps returning from Albert Road Recreation Ground, or midway across Caversham Heights, the engine may go rough, smoke, drop power, flash your dash or cut out. When you safely can, stop then turn it off — with no restarting to test. More of that is pulled through with each start.
On the M4, under 5 miles from Caversham Heights, the next junction is where to leave, and anywhere safe is where to stop — not driving on.
Hopping across Caversham Heights to the car park by St. Andrew's Church is one thing; driving for Oxford, under 25 miles away, is another, since every mile carries the AdBlue further in. So distance matters. About how far it had come is worth telling us.
Wherever the car came to a stop is where all of it gets done, even with more to clean out once the engine has been started. Spotted soon, it very seldom leaves lasting damage.
What does an AdBlue drain on a diesel involve in Caversham Heights?
Our technicians come to the car, wherever it has stopped around Caversham Heights: a side street close to Caversham Heights Methodist Church, a drive, a lay-by or a forecourt. Three answers decide the work, so first we ask which fluid got in, roughly the amount, plus whether your motor has run.
Next, emptying your tank on the spot removes the polluted diesel and the AdBlue in one go. A full flush counts much more with AdBlue than after petrol, because residue won't clear away on its own. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. The majority of these jobs are a half-hour job once our engineers get there, provided your motor has not run. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house at night.
The final step is to prime your system on new diesel. Starting the engine comes next, and then you drive off from where the vehicle is parked, by Reading or on a drive around Caversham Heights. We check it runs correctly on new diesel before we go. The entire job is done where the car is, so it never needs to be taken to a workshop. Afterwards, there is the paperwork for your insurer: a VAT invoice plus a written report from the engineer.

AdBlue in a diesel tank around Caversham Heights: the cost of fixing it
There's no fair single price, because the jobs aren't the same. Three things move the price: whether the engine has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one rests on whether our van can reach it safely, and an open drive is simpler than a tight gap behind St Peters Church.
That is why each call from Caversham Heights starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it has run. Given those replies, the range narrows to one firm number.
