Church Langley: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
Keep the engine and ignition off and call 0333 366 0103 now — reading can wait if AdBlue is already in your diesel tank. Caught before the engine runs, it is normally a drain and a thorough flush, done where the vehicle is around Church Langley. Reading in advance? Then what follows covers why it happens and what to prevent it ever happening.
AdBlue in a diesel vehicle: two tanks, two fillers
Many newer diesels on the roads around Church Langley and Harlow Common carry two liquids, not one. Diesel goes to the motor. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Different tanks, different fillers. Many of vehicles share a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. At the petrol pump, the diesel side gets filled constantly. Someone who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less regularly. It's in the gap that the error lives.
Church Langley: how AdBlue in the diesel tank occurs
Three things tend to come together, and carelessness is rarely one of them.
To start with, the warning. Low AdBlue brings a warning from the vehicle, and running dry means limp mode — hence a hurried top-up, perhaps before work off Old Hall Rise, or outside The Horns And Horseshoes on the way home after work.
New-to-you motors come next, as well. Hire cars, new motors and company cars place their fillers in new places, and the hand goes for the cap used on the old one.
Third, the bottle goes in: a diesel filler or AdBlue filler, it slides in just as readily, and after the pour starts, nothing halts it. Whether it happens in Foster Street or the middle of Church Langley, it's the same few seconds.
The AdBlue filler and the diesel filler: telling them apart
Before you tip anything, whether on a drive in Mark Hall South or a forecourt in Church Langley, check these. They take a few seconds.
- Where it sits misleads; the cap does not. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel ones usually do not.
- Plenty of vehicles fit AdBlue the smaller neck of the two.
- Look inside the fuel flap: many vehicles have a label there saying which fuel goes where.
- Cannot see it beside the diesel inlet? In that case check beneath the bonnet or in the boot — the handbook says which.
- The person who drove it last. On a hire or company car picked up from somewhere like the car park at Harlow Mill, ask before you leave, not when the light comes on.
Topping up AdBlue without it reaching the diesel tank
For the day the light appears — anywhere you are in Essex — a routine to use.
- Not in a rush on the side of Church Langley Way, not on a slope, not with the motor running: park then switch off properly.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
- Both behind one flap? Then make sure the lid on the diesel side stays shut before raising the bottle.
- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
- Before you start your car, shut the cap and check a second time that the diesel cap was never opened off.
Discover at the second or third stage that AdBlue went in the wrong filler? That is where you stop. Never carry on to stage five.
AdBlue in the diesel tank already, around Church Langley?
Short list, then. Top of that: the engine remains off. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel will not weaken it: instead, AdBlue sinks to the base of that tank, right where fuel is drawn from.
The attendants at Tesco, BP or any forecourt will normally lend a hand pushing the car clear if asked. On your own drive around Church Langley? So your car remains put.
Where your engine has run by now, stop somewhere safe then turn the vehicle off. Church Langley lies under a mile from the M11; there, use the next junction. Tell us roughly how far it went: a run towards Chelmsford, under 15 miles away, is a bigger job than a short hop across Church Langley.
Our arrival in Church Langley, and what happens next
The van reaches your car anywhere it has come to rest — your own driveway, beside Chinese Dynamic, or by Henry Moore Primary School. Our engineers ask what went in, about how much, and if it's run, because those answers settle this work and the quote. On the phone call itself, you hear our quote — before dispatch.
Then your tank is emptied and the system flushed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush matters more here than with petrol. After the fuel filter is cleaned — or renewed, if needed — fresh diesel is added, and finally your car is tested. The engine is started next and tested to be sure it runs properly, all before we go.
With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs where your motor hasn't run take roughly half an hour once our engineers are there. No money upfront; you settle up that day. Afterwards, a VAT invoice and a report from the engineer are handed to you for the insurer. Misfuelling cover is included in many insurance policies — so use the wait to look at yours.
