Five Acres: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
Keep the motor and ignition off and phone 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. Caught before your motor runs, it is usually a drain and a thorough flush, done where the vehicle is in Five Acres. If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it doesn't.
Two fillers, two tanks: AdBlue in a diesel car
Many modern diesels around Mile End, like those in Five Acres, carry on two fluids; your engine gets only the diesel. The exhaust, not your engine, is where AdBlue ends up: sprayed into the gas to clean them, from its own tank.
Each tank has one filler of its own. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel gets filled at each forecourt visit, week in, week out. Seldom topped up, AdBlue normally goes in out of a bottle, tipped by someone who must stop and think which filler it needs. The mistake lives in that gap.
How does AdBlue in your diesel tank take place around Five Acres?
Three things tend to line up, and carelessness is rarely one of them.
The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Crabtree Meadow before work, or in the car park at Gamekeepers Inn on the way home.
Then the car is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. The same few seconds settle it, in the middle of Five Acres or out in Berry Hill.
How to tell the AdBlue filler from the diesel one
Before you pour anything, whether on a driveway in Bakers Hill or a forecourt around Five Acres, check these. They take a few seconds.
- Where it sits misleads; the cap does not. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps normally do not.
- Check the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one.
- Lift the flap and check for a label — many cars mark what belongs in which inlet right there.
- Can't find it beside your diesel filler? In that case look beneath the bonnet or in the boot — the owner's manual says which.
- The person who drove the car last. On a hire or company car collected from somewhere like the car park at Lydney, ask before you leave, not when the light comes on.
Keeping AdBlue out of the diesel tank when you top up
For the day the light comes on — wherever it is around Gloucestershire — a simple routine to follow.
- Not in a rush on the side of Colliers Leaze, not on a slope, not with your engine running: park then switch off properly.
- Locate the AdBlue filler, read the cap, and say the word "AdBlue" out loud while unscrewing it. It sounds silly. It does the trick.
- The two under a single flap? Then make sure the cap on the diesel side is still closed before raising the bottle.
- Slowly is best, through the bottle's own spout, till it's full or the bottle runs out.
- Shut the cap, then check once more — making sure your diesel cap stayed shut the whole time. After that, start the car.
Discover at the second or third stage that the bottle went into the wrong tank? That's where you stop. Skip step five entirely.
Five Acres: already put AdBlue in your diesel tank?
Then the order of things is short. Do not start your motor. Keep your ignition off too, because on plenty of diesels it by itself runs the fuel pump. Topping up with diesel will not weaken it: instead, AdBlue sinks to the base of that tank, just where fuel is taken from.
At a forecourt — Texaco, BP or any other — the attendants will usually help roll the car clear, if you ask. If you are on your own driveway in Five Acres, leave the car where it stands.
Already run? Pull over when it is sensible, then switch off. The next exit is where to leave if you are on the M50, under 10 miles from Five Acres. Tell us about how far it went: a run towards Gloucester, under 25 miles away, is a bigger job than a short hop across Five Acres.
Five Acres: what takes place when we get there
By Berry Hill Primary School, close to Christ Church or on your own driveway: wherever your car has stopped, our technicians come to it. Both the work and the price depend on three replies — which fluid, what quantity, and whether it's run — so our engineers ask. No one sets off until you have heard the quote over the phone.
Then the tank is cleared and the fuel 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 with AdBlue than with petrol. Testing comes at the end: before that, clean diesel is added, and your filter is cleaned or changed if necessary. We don't go until it has been fired up and is running correctly.
If your motor hasn't run, most jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. No money in advance; you settle up on the day. At the end, a VAT invoice and a report from the engineer go to you for your insurer. Misfuelling cover is part of many insurance policies — and so use the wait to check yours.
