Westbury Leigh: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
Stop reading for a moment if your diesel tank already holds AdBlue in it: ignition off, engine off, then ring 0333 366 0103. Usually, if your engine has not turned, it's emptied and thoroughly purged where the vehicle is around Westbury Leigh. The rest of this page explains why it happens and how to make sure it does not — useful if you're reading ahead of time.
AdBlue in a diesel car, and its separate tank
Many modern diesels in Hisomley, like those in Westbury Leigh, run on two liquids; your engine gets only your diesel. Stored in a tank of its own, AdBlue is fed into the exhaust gas to clean it.
Each tank has its own filler. Under one flap, next to each other: that is the layout on a lot of motors. On others, AdBlue's filler is beneath the bonnet or in your boot instead. The diesel side is filled at the pump all the time. Seldom filled, AdBlue usually goes in from a bottle, poured by someone who must stop and think what filler it needs. It's in the gap that the error lives.
AdBlue in the diesel tank around Westbury Leigh: how it takes place
It's seldom carelessness. Three things tend to line up.
To start with, the warning. Low AdBlue triggers a message from your car, and letting it run out means limp mode — so a hurried top-up, maybe before work off Blackhorse Lane, or outside The Hollies Inn on the way home after work.
Then the car is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and your hand hits for the cap it would have used on the old one.
Lastly, the bottle goes in: a diesel filler or AdBlue filler, it goes in as readily, and after the pour starts, no part halts it. Chalford or the middle of Westbury Leigh: it is the same few seconds either way.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all the checks take — so check them before you tip anything, on a drive in Old Dilton or a forecourt in Westbury Leigh.
- Check the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps normally aren't.
- The size. On many cars the AdBlue filler neck is the smaller of the two.
- Lift the filler flap and look for a label — many vehicles show what goes in which inlet just there.
- The handbook shows which it is when the filler is not next to the diesel cap: your boot, or under the bonnet.
- The previous driver knows. Ask when you pick up a hire car or fleet car — at Dilton Marsh's car park, say — rather than when the light comes on.
AdBlue top-ups that never reach your diesel tank
On the day the light appears — wherever you are around Wiltshire — a simple routine to follow.
- Not in a rush on the side of Oldenburg Road, not on a slope, not with your engine running: park and switch off properly.
- Silly as it sounds, saying "AdBlue" aloud while you unscrew the cap works — after you have found your filler and read the cap.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Only after that, start your car: close the cap, check again, and make sure your diesel cap was never opened.
Stop there if you find, at step two or three, that you've already poured into the diesel side. Never go on to step five.
Westbury Leigh: already put AdBlue in the diesel tank?
Do not start your motor: that's where the short order of things starts. Keep the ignition off as well, because on many diesels it by itself starts your pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is drawn from — so don't top up with diesel to thin it.
The attendants at Esso, BP or another forecourt will usually help pushing the car away when asked. Leave it where it is if you're on your own drive in Westbury Leigh.
If your motor has already run, stop as soon as it is safe and switch off. Leave the M4 — under 25 miles out of Westbury Leigh — at the next junction. Roughly how far did it go? Hopping across Westbury Leigh is smaller a job than a run of under 15 miles towards Bath, so tell us.
Our arrival around Westbury Leigh, and what happens next
The van reaches the car anywhere it stopped — your own drive, beside Westbury Leigh Community Hall, or outside Westbury Leigh CofE Primary School. Both the work and the price rest on three replies — what fluid, what amount, and if it has run — so our technicians ask. The quote comes over the phone, ahead of any van leaving.
The system is then purged thoroughly, once the tank is drained. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of it washes away unaided. Hence it counts more. Filter flushed or, if needed, swapped; clean diesel in; then a check of your vehicle. The motor is started next and checked to confirm it runs correctly, all before our engineers leave.
If the motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. No money upfront; you settle up that day. At the end, the VAT invoice and a report from the engineer are handed to you for your insurer. Before we get there, have a look at your policy; many carry cover for misfuelling.
