AdBlue in a Diesel Tank in South Hornchurch? Don't Start It
AdBlue in the diesel tank? Then leave the motor off — and your ignition as well. Water with urea mixed in it: that is AdBlue. Unlike fuel, it neither burns nor mixes, and no harm starts until the engine sucks it round. In South Hornchurch, AdBlue in a diesel tank caught before the motor runs usually means a drain and a thorough flush, right where the vehicle is. Before you do anything else, phone 0333 366 0103.
AdBlue in your diesel tank around South Hornchurch: the first few minutes
Things to do:
- Keys out — that way nobody can switch anything on.
- Put the hazards on if you're at all near moving traffic.
- Keep the till receipt or the empty bottle, and so you can tell us what was put in and roughly how much.
- Ring right where you are. Quote a RM13 8 postcode or the closest street name, and no one has to search for you.
Don't:
- No starting the engine — not briefly, not to reposition your car.
- The ignition remains off: on many diesels, turning it on is enough to start the fuel pump.
- Adding more diesel doesn't help: AdBlue settles out rather than blending.
- Any driving at all is best avoided, even a short distance down Stanley Road South.
- No emptying it yourself, at all, at the verge.
Moving the vehicle away from the pumps is a job for staff to help with, whichever South Hornchurch forecourt you're on, the the nearest petrol station or any other. On the drive, the vehicle remains exactly as it was left.
What AdBlue does in a diesel tank
The motor isn't what AdBlue is made for; the exhaust is. Stored in a separate tank, it's squirted into the exhaust stream to treat the fumes. Nothing inside a fuel pump is designed for this liquid — and no part of that was intended to go that way.
Tipped in with your diesel, it keeps separate rather than mixing — quite unlike fuel. Heavier than diesel, it sinks and collects underneath it — the very spot the intake draws from. Easiest of all: one that had AdBlue in Hacton last night and hasn't turned since. The AdBlue sits at the base of the tank, untouched — though it will be first through if the engine runs, before any diesel at all.
From there it causes 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 working on the components it gets to for as long as it stays there. A vehicle left sitting in South Hornchurch 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 harm of its own: the high-pressure pump and your injectors rely on diesel to lubricate them, and water offers them nothing.
Petrol or AdBlue in a diesel: why AdBlue is commonly worse
A problem of thin fuel is what you get after fuelling a diesel with petrol at the Esso. No harm is done as long as it sits unused, blended into the diesel — only once the engine works on it.
AdBlue in a diesel is an issue of the wrong substance altogether. It doesn't burn, so it cannot simply be run through. It doesn't stay mixed, so it can't be weakened. 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 your engine "to see" costs more here than almost anywhere else, whether your car is in Wennington or the middle of South Hornchurch.
The same good news holds as with petrol. Never started? Then the AdBlue waits only in the tank, the simplest bit of the entire system to clear, wherever your vehicle has come to rest across Greater London.
How AdBlue ends up in a diesel tank in South Hornchurch
No one means to do it. The AdBlue filler on many motors sits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Usually it is not the forecourt: someone buys a container heading home and tips it in outside the house.
A few familiar ways account for most cases. A warning light comes on during the school run, and the top-up occurs in a hurry outside La Salette Catholic Primary School. Near Cherry Tree Lane, a driver pours a bottle in at home after work. Or a driver new to that flap tops up the vehicle in dim light, parked in the car park by The Albion.
It occurs most in the cars motorists know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you are around South Hornchurch or the remainder of Greater London, it's the same slip and the same first answer: leave the vehicle off.
Already started the engine with AdBlue in the diesel tank around South Hornchurch?
In that case, the AdBlue is no longer in the tank. Via your filter, through the lines, and — with any running time — on to the high-pressure pump and each injector: that's how far it has gone.
Watch for rough running, smoke, lost power, lights on your dash, or a cut-out — coming back from Lessa, say, or midway across South Hornchurch. Stop when safe. Switch off. Leave the car off instead of restarting it to check. With each start, more of that is pulled through.
On the M25, under 5 miles from South Hornchurch, the next junction is where to exit, and somewhere sensible is where to stop — not driving on.
How far it went counts. A couple of hundred yards across South Hornchurch to the car park by Whybridge Christian Fellowship Church is a very different job from a run towards London, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile. Let us know roughly how far it had come.
Our engineers do all of the rinsing where your car has come to a stop, and once the engine has been started there is more of it. Noticed soon, it very seldom leaves lasting damage.
What emptying AdBlue from a diesel involves in South Hornchurch
A road beside South Hornchurch Library, a driveway, a lay-by or a filling station: wherever the car has stopped in South Hornchurch, our technicians travel to it. Three replies shape the job, so before anything else we ask which fluid was put in, about what quantity, plus whether the engine has turned over.
The polluted diesel and the urea come out together after the tank is drained, on the spot. Residue from AdBlue won't flush away by itself, and so the whole system gets a careful flush, which counts much more here than with petrol. Next, the fuel filter: cleaned, or replaced if it must be. After that fresh diesel, and then a check of your car. If your motor hasn't run, most jobs take about half an hour once we are there. Our equipment is explosion-proof, so a live forecourt is no problem, and it is quiet enough for a residential street late at night.
The last step is to bleed your system on fresh diesel. Firing it up comes next, and then you set off from where your car is parked, outside Rainham (Essex) or on a driveway around South Hornchurch. Before we go, we make sure it's running properly with clean diesel in. The whole job is done where the car is, so it never needs to be taken to a garage. Insurers ask for a VAT invoice and an engineer report, and you get both at the end.

South Hornchurch: what AdBlue in a diesel tank costs to fix
Every job differs, so not one fixed price is fair. Three things move the price: whether your engine has been running and for how long, how much AdBlue got in, and where the vehicle is. That last one rests on whether a van can reach it safely, and an open drive is easier than a tight spot behind South Hornchurch Community Hall.
With that reason, each call from South Hornchurch opens by asking the identical trio — which fluid was put in, how much, whether it ran — ahead of a figure. With them, the range narrows to one firm figure.
You hear that price on the phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
