AdBlue in a Diesel Tank in High Bonnybridge: Why It Happens and How to Avoid It
Pause here a minute when the diesel tank already holds AdBlue in it: ignition off, motor off, then phone 0333 366 0103. A drain and a thorough flush, done right where your car stands in High Bonnybridge, is normally what it takes if caught before the engine runs. Nothing happened yet? Below, the rest of the page explains the reasons it happens and the ways to prevent it altogether.
AdBlue in a diesel vehicle, and its separate tank
Diesel feeds the engine — but plenty of current diesels driven around High Bonnybridge and Milnquarter hold a second fluid too. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
Each tank has its own filler. Plenty of motors share a single flap for both, while others put the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled all the time. The AdBlue side is fuelled far less commonly, normally from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the mistake lives.
How AdBlue in your diesel tank happens around High Bonnybridge
Carelessness rarely causes it. Instead is three things coming up together.
Haste comes from the warning. The car tells you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up gets done quickly, before work on a drive off Lochinvar Place, or on the way home in the car park at Broomhill Inn.
Next, the hand reaches for the cap it would have used on the old motor — since a rental car, a new vehicle or a company car puts the fillers somewhere your last one did not.
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. It's a few seconds, whether out in Greenhill or right in the centre of High Bonnybridge.
Which filler is for AdBlue, and which for diesel?
Before you tip anything, whether on a driveway in Dennyloanhead or a forecourt around High Bonnybridge, check these. They take a couple of seconds.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by where it sits.
- Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one.
- Look inside the fuel flap: plenty of vehicles have a label there showing which fuel goes where.
- Cannot find it next to your diesel filler? Then check below the bonnet or inside the boot — the handbook says which.
- Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Camelon.
Topping up AdBlue without it reaching the diesel tank
For the day the warning comes on — anywhere it is in Falkirk — a routine to follow.
- Stop on level, motor off, with time in hand — not hurried on the side of Church Street.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
- The two under one flap? So confirm the cap on your diesel side is still shut before lifting the bottle.
- Slowly is best, through the bottle's own spout, until it's full or the bottle runs out.
- Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the car.
If at stage two or three you find you have already poured into your diesel side, stop there. Don't go on to stage five.
Already put AdBlue in your diesel tank around High Bonnybridge?
Brief list, then. Top of that: the motor stays off. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel fails, because AdBlue settles to the base rather than blending — and that is where your fuel is sucked from.
The staff at JET, BP or another forecourt will usually lend a hand to push the car clear when asked. Your own drive around High Bonnybridge is where it should stay.
Already run? Stop once it is sensible, then switch off. On the M876, under 3 miles from High Bonnybridge, that means the next junction. Distance counts — a quick hop across High Bonnybridge is a smaller job than heading under 10 miles to Stirling — so say about how far it went.
When our engineers turn up in High Bonnybridge, what happens?
By the local primary school, close to St Joseph's or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Both the work and the price depend on three replies — which liquid, which amount, and whether it has run — so our technicians ask. On the phone call itself, you are told the price — ahead of dispatch.
Draining your tank comes next, followed by a full flush of the fuel system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more here than with petrol. Testing comes last: before that, clean diesel goes in, and your filter is cleaned or replaced as needed. Before leaving, we fire it up and check that it is running properly.
Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine has not run need roughly half an hour after our technicians are there. Your insurer usually wants an engineer's report and your VAT invoice, and you get both once this job is done. Payment comes on the day, with no money upfront. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
