Avoiding AdBlue in a Diesel Tank in Mount Ambrose: Why It Occurs
Leave the engine and ignition off then call 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. Usually, if your engine has not run, it is emptied and thoroughly purged where your car sits in Mount Ambrose. Nothing happened yet? Below, the page covers the reasons it happens and the ways to avoid it altogether.
Two fillers, two tanks: AdBlue in a diesel motor
Plenty of newer diesels around Higher Ninnis, like those in Mount Ambrose, run on two liquids; the motor gets just your diesel. AdBlue's own tank holds it, and from there it is sent to the exhaust, and there a spray treats the fumes.
Different tanks, different fillers. Under one flap, side by side: that is the layout on a lot of motors. On others, AdBlue's filler sits beneath the bonnet or in your boot instead. Diesel gets filled at each filling station visit, again and again. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less often. It is in the gap that the error lives.
AdBlue in the diesel tank in Mount Ambrose: how it occurs
It's hardly ever carelessness. Three things tend to line up.
Hurry follows from the warning. The car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Elvan Mews, or heading home in the car park outside The Mount Ambrose Inn.
Unfamiliar cars come next, as well. Rentals, new cars and company vehicles put their fillers in new places, and habit reaches for the cap used on the old one.
Third, the spout fits: diesel filler or AdBlue filler, it goes in just as readily, and after the tip begins, nothing halts it. It's seconds, whether in Treskerby or bang in the centre of Mount Ambrose.
How to tell the AdBlue filler from the diesel one
A few seconds is all the checks take — so check them before you pour anything, on a drive in Lower Ninnis or a forecourt around Mount Ambrose.
- Blue and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not where it sits.
- The size. On many vehicles the AdBlue filler neck is the smaller of the two.
- Open the filler flap and check for a label — plenty of vehicles show which belongs in each filler right there.
- Can't find it next to your diesel inlet? In that case look beneath the bonnet or in your boot — the owner's manual says where.
- Whoever had it before knows. Check as you pick up a rental or company car — at Redruth's car park, perhaps — not when the warning appears.
Keeping AdBlue out of your diesel tank when you top up
A routine for the day the light comes on, wherever across Cornwall that is.
- Not in a rush on the side of Highway Lane, not on a slope, not with the motor running: park then switch off properly.
- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, yes, yet it works.
- Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Slowly does it, through the bottle's own spout, till it is full or the bottle is empty.
- Close the cap, and check once more — confirm your diesel cap remained shut the whole time. Only then, start the vehicle.
Discover at the second or third stage that the bottle went in the wrong filler? That's where you stop. Leave out stage five altogether.
Mount Ambrose: already put AdBlue in the diesel tank?
Then the order of things is short. Do not start your engine. Leave the ignition off as well, because on many diesels switching it on by itself starts the fuel pump. Topping up with diesel won't weaken it: instead, AdBlue drops to the bottom of that tank, just where fuel is taken from.
On a forecourt — Texaco, Tesco or any other — the staff will normally help roll your car clear, when you ask. On your own drive in Mount Ambrose? So your car stays where it is.
Already run? Pull over once it is sensible, then turn off. On the M5, over 50 miles from Mount Ambrose, that means the next junction. Roughly how far did it go? Hopping across Mount Ambrose is less work than a trip of under 10 miles towards Truro, and so tell us.
Our arrival around Mount Ambrose, and what takes place next
Our engineers come to your car wherever it has stopped, whether that's outside Treleigh Community Primary School, near The Church of Jesus Christ of Latter-day Saints or on your own drive. The replies determine this work and the price, and so our technicians ask what was put in, about how much, and if it's run. During the call itself, you hear our price — ahead of anything else.
Next: a drain, then a thorough flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that counts more with AdBlue than with petrol. After your filter is cleaned — or replaced, where needed — clean diesel is added, and finally your vehicle gets tested. The engine is started next and checked to be sure it runs smoothly, all before our technicians leave.
With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine hasn't run take about half an hour after our engineers arrive. Paying happens on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
