AdBlue in a Diesel Tank in Caulcott: How It Occurs and How to Avoid It
AdBlue already in the diesel tank? In that case set this page down for now, leave your ignition and engine off, and phone 0333 366 0103. Usually, when the motor has not turned, it's emptied and thoroughly rinsed where your car is in Caulcott. Here in advance? Then the rest covers how it happens and how to prevent it ever happening.
Why does AdBlue in a diesel car need its own filler?
Diesel feeds the motor — but plenty of modern diesels seen about Caulcott and Upper Shelton carry a second fluid too. Kept in a tank of its own, AdBlue is fed into your exhaust gas and cleans it.
Different tanks, separate fillers. Many of motors have a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. Diesel goes in at every forecourt visit, week in, week out. Much less often, the AdBlue side gets filled — normally from a bottle, by a person working out where it goes. It's in that gap that the error lives.
Caulcott: how AdBlue in the diesel tank happens
Seldom is it carelessness: normally three things line up.
Haste comes from the warning. Your car tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up happens quickly, before work on a driveway off Bedford Road, or heading home in the car park at The Bell.
Unfamiliar vehicles come next, as well. Hire cars, new motors and company vehicles put their fillers differently, and the hand reaches for the cap it used on the old one.
Nothing halts the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Lower Shelton or the heart of Caulcott: it is the same few seconds either way.
How to tell the AdBlue filler from the diesel one
Be it a Caulcott forecourt or a driveway over in Stewartby, spend a couple of seconds over these before any goes in.
- Colour and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally does not. Go by the cap, not where it sits.
- Plenty of vehicles give AdBlue the smaller neck of the two.
- Check inside your fuel flap: many motors have a label there showing which fuel goes where.
- The handbook. If the filler isn't by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
- Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Stewartby.
Keeping AdBlue out of your diesel tank when you top up
For the day the warning appears — wherever you are in Bedfordshire — a simple routine to follow.
- Not in a rush on the side of Lakeview, not on a slope, not with the engine running: park then switch off properly.
- Find the AdBlue filler, check the cap, and speak the word "AdBlue" out loud as unscrewing it. It sounds silly. It does the trick.
- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Shut the cap, and check once more — confirm the diesel filler remained shut throughout. Only then, start your car.
Spot at stage two or three that it has already gone into the diesel side? So stop just there. Never go on to step five.
AdBlue in the diesel tank already, around Caulcott?
Short list, then. Top of that: the engine remains off. On many diesels the ignition alone runs the fuel pump, so don't switch the car on. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from.
On a forecourt — the nearest petrol station, Shell or another — the attendants will usually help push your car away, when you ask. Your own driveway in Caulcott is the place it should stay.
Already started? Pull over when it is safe, then switch off. The next exit means the place to come off if you are on the M1, under 5 miles from Caulcott. Mileage matters — a short hop across Caulcott is a smaller job than driving under 10 miles to Milton Keynes — so tell us about how far it went.
When our technicians turn up in Caulcott, what takes place?
Wherever the car has stopped, be it by Marston Moreteyne VC School, beside Marston Village Hall or at home, the van travels to it. Our technicians ask what got in, roughly how much, and if it has run, because those answers decide this work and the price. No one heads out until you've heard the quote over the phone.
Draining your tank comes next, then a full flush of your system. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither clears out by itself. Hence it matters more. Testing is last: before that, fresh diesel goes in, and the filter is flushed or changed if necessary. Before leaving, our technicians fire it up and confirm that it's running correctly.
Most jobs are done in roughly half an hour once our technicians get there, as long as the motor has not run — and the pumps our engineers use are safe on a busy forecourt yet quiet at night beside a house. Paying is on the day, not upfront, and you receive the documents an insurer asks for: an engineer report and a VAT invoice. Many insurance policies include misfuelling cover, so it is worth checking yours while we are on the way.
