AdBlue in the Diesel Tank in South Ruislip? Keep It Switched Off
If AdBlue has gone into the diesel tank, leave the motor off then keep the ignition off. Water with urea dissolved in it: that's AdBlue. The harm begins once it is sucked through the pump — it won't ignite, and it will not blend with diesel. A drain and a thorough flush, done where your car is in South Ruislip, is usually all AdBlue in a diesel tank takes — if it's caught before the engine has run. Before you do anything else, call 0333 366 0103.
South Ruislip, AdBlue in your diesel tank: what to do right away
Do:
- So nobody can switch the ignition on, pull the keys out.
- Close to moving traffic? So put your hazards on.
- The empty bottle or the receipt tells us the fluid and the quantity, so do not throw it out.
- The van finds you fastest with a postcode starting HA4 0, or simply the name of a street close by, so phone from the spot.
Do not do these:
- No starting your motor — not briefly, not to reposition your vehicle.
- Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.
- Adding extra diesel doesn't work: AdBlue settles out instead of thinning.
- Keep the vehicle where it is instead of driving it anywhere, even a short way up Long Drive.
- By the road, do not try emptying it on your own.
At a forecourt around South Ruislip, whether it's the BP or another one, ask the attendants to help you roll the vehicle clear of the petrol pump. At home, your car stays exactly where it was left.
What AdBlue does in a diesel tank
The engine is not what AdBlue is made for; the exhaust is. Its own tank holds it, and from there it's sprayed into the exhaust, where it treats the fumes. A fuel pump is not designed to cope with it, and AdBlue was never intended to travel through one.
It does not blend. Once it is poured into a tank of diesel, AdBlue behaves nothing like fuel. Heavier than diesel, it drops and pools below it — the same place the intake draws from. When the system runs, the AdBlue is top of the list to be pulled through. Before then it waits underneath your diesel, which is why a vehicle filled in Northolt last night and not switched on remains the simple one, provided no one turns the key.
Two kinds of harm follow from there. What is left when the water evaporates is urea, which forms crystals: they lodge in tiny channels and clog filters. On top of that, it eats at some metals in a fuel system, and carries on until it's cleared out. A vehicle left standing around South Ruislip with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. The water in it does damage of its own: the high-pressure fuel pump and the injectors depend on diesel to lubricate them, and water offers them nothing.
AdBlue in a diesel: why it is often worse than petrol
Put petrol in a diesel at the Sainsburys and you have a fault of thin fuel. No damage is done as long as it stays unused, mixed into the diesel — only once the motor works on it.
With AdBlue in a diesel, the fluid as such is simply the wrong one. Since it doesn't burn, running it through is not an option. It doesn't stay mixed, and so it can't be thinned. 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 engine "to see" costs more here than nearly anywhere else, whether your car is in Rayners Lane or the middle of South Ruislip.
With AdBlue, the good news is no different from petrol. Clearing a tank is the simplest part on a fuel system, and with no start-up, the AdBlue stays in there — wherever across Greater London your vehicle has stopped.
How AdBlue ends up in a diesel tank in South Ruislip
After dark, two caps together — the AdBlue cap and the diesel cap, now and then under a single flap — can appear the same. No one intends it; plenty of layouts invite it. It usually happens outside the house, from a container bought en route home, not at the forecourt.
It tends to occur in a couple of familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside Deanesfield Primary School the refill is rushed. In the evening, a container goes in on a drive near The Fairway. Else, after dark outside The Middlesex Arms, the vehicle is topped up by someone using that flap for the first time.
It takes place most in the cars motorists know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you're around South Ruislip or the remainder of Greater London, it's the same error and the same first answer: leave the car off.
Started the engine with AdBlue in your diesel tank around South Ruislip?
If so, the AdBlue is no longer in the tank. Via your filter, along the pipework, and — given any running — into the injection pump and every injector: that's how far it travels.
Expect lumpy running, smoke, lost power, warnings on your dash, or a stall — returning from Crossway Green, perhaps, or midway across South Ruislip. Pull over when safe. Switch off. Keep the car off rather than restarting it to check. Each start pulls more of that through.
If you were on the M40, under 5 miles from South Ruislip, come off at the next junction and stop somewhere safe rather than pressing on.
How far it went counts. A couple of hundred yards across South Ruislip to the car park by South Ruislip Library is a very different job from a run towards Westminster, under 15 miles away, with the AdBlue reaching further into your system with each mile. Roughly how far had it come? Tell us.
There's more to rinse out once the engine has run, and we do all of it where the vehicle has come to a stop. Noticed early, it very rarely leaves long-term damage.
South Ruislip: how AdBlue is cleared from a diesel
Wherever it has come to rest around South Ruislip — a filling station, a layby, a drive, a street beside Saint Mary — our van comes to your vehicle. Three replies shape the job, so before anything else our technicians ask which fluid was put in, about what quantity, plus whether your engine has turned over.
Then the tank is emptied where the car waits, so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the fuel system is cleaned right through because residue won't wash away by itself. Fresh diesel goes in after the filter is cleaned — or replaced, when it needs to be — and after that the car is tested. If the motor has not run, the majority of jobs take about half an hour once our engineers are there. Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough to spare the street at night.
The final step is to bleed your system on fresh diesel. At that point our engineers fire it up and you set off, whether from a parking space by the nearest station or a drive around South Ruislip. Our technicians make sure it runs correctly on fresh diesel before leaving. No workshop is needed at any point, with the whole job done then and there. You get a VAT invoice and an engineer report later, which is what insurers want.

South Ruislip: what AdBlue in a diesel tank costs to fix
Because each jobs differ, a single figure wouldn't be honest. Whether the engine has run, and for how long, comes first in what moves the price. How much AdBlue was put in comes next, and then the location of the car, since an open driveway is simpler for our van to reach safely than a tight space behind South Ruislip Young Peoples Centre.
Ahead of a quote, not afterwards, each enquiry from South Ruislip begins with the same three questions: the liquid, the quantity, plus if the engine ran. Those replies narrow a range right down to a single number.
The quote is quoted on the call, before a van sets off; settling up happens on the day, by card or over the phone, and nothing upfront. Check your policy whilst we're on the way: many carry misfuelling cover.
