AdBlue in a Diesel Tank in Hainault? Don't Start It
With AdBlue in your diesel tank, your ignition stays off and so does your engine. Urea dissolved in water is what AdBlue is. Not like fuel, it neither ignites nor blends, and no harm happens till your engine sucks it through. A drain and a thorough flush, done where your car is in Hainault, is usually what AdBlue in a diesel tank needs — if it's caught before your motor has been run. Phone 0333 366 0103 before you do anything else.
What to do straight away, Hainault: AdBlue in the diesel tank
Do:
- Take the keys out, and so nobody switches your ignition on.
- Hazards on, if moving traffic is anywhere close.
- Which fluid, and about what quantity? Save the bottle or the till receipt, and our technicians can see.
- Call just where you are. Quote a IG7 4 postcode or the closest street name, and no one has to search for you.
Not to do:
- Don't start your engine, even for a moment to shift your car.
- The ignition stays off: on lots of diesels, turning it on is enough to start the pump.
- No extra fuel on top. The AdBlue will not blend, so it is pointless.
- Any driving at all is to be avoided, even a short way up Staggart Green.
- No emptying it yourself, at all, on the verge.
Ask the attendants to help you move the vehicle away from the pumps if you're on a forecourt in Hainault, whether it is the JET or somewhere else. At your own driveway, do not touch it at all.
AdBlue in a diesel tank: what it does
The engine is not what AdBlue is made for; the exhaust is. Its own reservoir keeps it, and from there it's fed into your exhaust, where it cleans the gas. A fuel pump is not made to take it, and AdBlue was never intended to go through one.
Inside a diesel tank it acts very differently from fuel. It doesn't mix in. It's heavier than diesel, so it sinks and gathers at the bottom of your tank, which is where the pickup draws fuel from. Once your system runs, the AdBlue is first to be pulled through. Before then it sits beneath the diesel, which is why a car filled in Fullwell Cross yesterday and not started stays the straightforward case, as long as nobody turns your key.
Once it's sucked in, the harm comes in two forms. What is left once the water evaporates is urea, which turns into crystals: they lodge in narrow passages and block filters. On top of that, it eats at some metals in a fuel system, and keeps going until it is cleared out. Pipes carrying AdBlue spell damage by morning for a vehicle sitting around Hainault. Just inside that tank, it stays the same. The water in it causes damage of its own: the high-pressure fuel pump and the injectors rely on diesel to lubricate them, and water gives them nothing.
Why is AdBlue in a diesel often the bigger fault?
Top up a diesel with petrol in error over at the Shell, and this problem is thinned fuel. No damage is done as long as it sits unused, mixed into the diesel — only once the motor runs on it.
With AdBlue in a diesel, the liquid as such is plainly the wrong one. Because it doesn't burn, running it through is not an option. It does not stay mixed, and so it can't be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than almost anywhere else, whether the car is in Alderwood Terrace or the middle of Hainault.
With AdBlue, the good news is no distinct from petrol. Clearing a tank is the easiest part on a fuel system, and with no start-up, the AdBlue stays in there — anywhere in Greater London your vehicle sits.
How does AdBlue end up in a diesel tank in Hainault?
It is not on purpose. Plenty of vehicles keep the AdBlue inlet beside the diesel inlet, now and then behind one flap, and mixing them up is simple in poor light. Mostly it takes place with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
The ways it happens are few and familiar. Hurrying, outside John Bramston Primary School, after a warning light came on during the school run, a parent refills the vehicle. A bottle is poured in at the end of the day on a drive just off Hursley Road. One more version: darkness, a pub car park by the pub in the village, and a driver using that flap for the first time.
It comes up the most in a hire car, a new motor, a company vehicle, or the spare vehicle of a home with both fuels — the cars people know the least. An identical slip, an identical first step — leave it off — wherever you happen to be around Hainault or the rest of Greater London.
AdBlue in your diesel tank around Hainault, and the engine started?
Then that tank is no longer where the AdBlue is. Via the filter, along the lines, and — with any running time — on to the high-pressure pump and every injector: that's where it has gone.
Watch for lumpy running, smoke, falling power, warnings on your dash, or a cut-out — returning from Hainault Recreation Ground, perhaps, or midway across Hainault. No starting it again to test: stop when safe, then switch it off. Each start pulls more of it through.
Leave the M11, under 3 miles from Hainault, at the next junction and park safely, not carrying on.
How far it went counts. A couple of hundred yards across Hainault to the car park by Hainault Forest Community Association is a very different job from a run towards London, under 15 miles away, with the AdBlue reaching further into your system with every mile. Roughly how far had it come? Tell us.
There is more to flush once your engine has been started, and we do all of it where the vehicle has ended up. Very seldom does it leave long-term damage when it is caught early.
Emptying AdBlue in a diesel in Hainault: what it takes
A road by Hainault Library, a drive, a lay-by or a filling station: anywhere the car has stopped in Hainault, our technicians come to it. Three answers decide the work, and so before anything else we ask what was put in, roughly the amount, plus if the motor has turned over.
Then your tank is drained where your car stands, and so the contaminated fuel and the AdBlue come out together. Your system is purged thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. Clean diesel goes in once your filter is flushed — or replaced, if it needs to be — and then your vehicle is tested. Most of these jobs are a half-hour job once we get there, if the engine hasn't run. Quiet enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.
The final step is to bleed the fuel system on new diesel. After that we fire it up and you drive off, whether from a parking bay by Chadwell Heath or a drive around Hainault. The check before we head off is that it runs correctly on clean diesel. The whole job is done where the vehicle is, so it never has to be taken to a garage. Insurers ask for a VAT invoice and an engineer report, and you get both at the end.

Hainault and Greater London: AdBlue drains across the area

Hainault: what AdBlue in a diesel tank costs to fix
Every job differs, and so not one fixed quote would be fair. Three things change the price: whether the motor has run and for how long, how much AdBlue went in, and where the vehicle is. That last one turns on whether a technician can reach it safely, and an open drive is simpler than a tight gap behind Church Of The Assumption.
That's why each call from Hainault starts with the same three queries, asked before giving a figure, not after: what went in, how much, and whether it's run. When they are known, a range becomes a single firm number.
The price is given on the call, before a van sets off; settling up comes on the day, by card or by phone, and nothing upfront. Misfuelling cover comes with many insurance policies, so it pays to look at yours before the van arrives.
Next to the car around Hainault, still?
