Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Carshalton Beeches
Leave the motor and ignition off then call 0333 366 0103 first — reading can wait if AdBlue is already in your diesel tank. Normally, when the engine has not run, it is emptied and thoroughly rinsed where the vehicle sits in Carshalton Beeches. Here before the event? In that case the rest covers how it happens and what to stop it happening at all.
Two fillers, two tanks: AdBlue in a diesel motor
Not one fluid but two: that's how plenty of modern diesels near Carshalton Beeches and Little Woodcote run, with diesel for your engine. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Different tanks, different fillers. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the petrol pump, the diesel side is topped up constantly. Much less frequently, the AdBlue side is filled — mostly from a bottle, by someone thinking about where it goes. It is in the gap that the slip happens.
AdBlue in the diesel tank in Carshalton Beeches: how it takes place
Carelessness rarely explains it. Instead is three things lining up together.
The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Beeches Walk before work, or in the car park outside The Old Bank on the way home.
Then your car is new. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one.
A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the pour, after begun, keeps on. It takes seconds, whether in Carshalton on the Hill or right in the centre of Carshalton Beeches.
The AdBlue filler and your diesel filler: telling them apart
Be it a Carshalton Beeches forecourt or a driveway out in Carshalton, take a couple of seconds over these before anything goes in.
- Where it sits misleads; the cap does not. AdBlue caps are often blue or bear the word "AdBlue" — diesel ones normally do not.
- Look at the size: the smaller neck is, on plenty of vehicles, the AdBlue one.
- Open the flap and check for a label — many motors mark what goes in each inlet right there.
- The handbook. If the filler isn't by your diesel cap, it is in your boot or under the bonnet, and the handbook says which.
- Whoever had it before knows. Ask when you pick up a rental or fleet car — from the nearest station's car park, say — rather than once the warning comes on.
How to top up without AdBlue in your diesel tank
A routine for the day the light comes on, wherever around Greater London that is.
- Not in a rush on the side of Banstead Road, not on a slope, not with your engine running: park then switch off first.
- Find the AdBlue filler, read the cap, and speak the name "AdBlue" out loud while you unscrew it. It sounds silly. 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.
- Gently does it, through the bottle's own spout, until it's full or the bottle runs out.
- Only after that, start the car: close the cap, check once more, and make sure your diesel cap was never opened.
If at stage two or three you find you have already poured into your diesel side, stop there. Skip stage five entirely.
AdBlue in the diesel tank already, in Carshalton Beeches?
Brief order, then. First: the engine remains off. Keep the ignition off as well, because on many diesels it alone runs your pump. Diluting it with extra diesel won't work, because AdBlue settles to the base rather than blending — and that's where your fuel is drawn from.
On a forecourt — BP, Shell or another — the attendants will normally help push the vehicle away, if you ask. Your own drive around Carshalton Beeches is the place it should stay.
Stop as soon as it is safe then switch off, if your motor has already run. On the M23, under 5 miles from Carshalton Beeches, that means the next exit. Distance matters — a short hop across Carshalton Beeches makes a smaller job than heading under 15 miles to Westminster — so tell us about how far it went.
What occurs when our technicians turn up around Carshalton Beeches
Anywhere the vehicle came to rest, whether outside Barrow Hedges Primary School, beside Sutton Tennis & Squash Club or on your own drive, the van travels to it. Which fluid went in, the quantity, and if it ran: our engineers ask since the replies decide the work and price. That price comes over the phone, before any van leaves.
Draining your tank comes next, followed by a full flush of the 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 the flush matters more here than with petrol. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. After that we start the car and confirm it runs smoothly before leaving.
If your engine has not run, most jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. Payment happens on the day, not upfront, and you are given the documents your insurer asks for: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way.
