Avoiding AdBlue in a Diesel Tank in Weybridge: Why It Occurs
Leave the engine and ignition off and ring 0333 366 0103 now — reading can wait when AdBlue is already in your diesel tank. In Weybridge, catching it before the engine runs usually leaves draining and a full flush on the spot. Not happened yet? Below, the page covers the why it takes place and the ways to avoid it altogether.
AdBlue in a diesel vehicle: two tanks, two fillers
No single liquid but two: that is what many modern diesels around Weybridge and Hamm Moor run, with diesel for the engine. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.
There is a filler for each tank. Under one flap, side by side: that is the layout on a lot of vehicles. On others, AdBlue's filler sits under the bonnet or in the boot instead. At the petrol pump, your diesel side gets filled all the time. Much less frequently, the AdBlue side is topped up — normally from a bottle, by a person working out where it goes. It is in that gap that the error happens.
How does AdBlue in your diesel tank happen around Weybridge?
Carelessness seldom explains it. Instead is three things coming up together.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Church Street before work, or in the car park at The Queens Head on the way home.
Then, the hand reaches for the cap it would have used on the old motor — since a rental car, a new motor or a company car puts the fillers where your last one didn't.
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 once it has started. It takes a few seconds, whether out in Hamhaugh Island or right in the heart of Weybridge.
How to tell the AdBlue filler from the diesel one
Be it a Weybridge forecourt or a driveway out in Pharaohs Island, take a few seconds on these before anything is poured in.
- Blue and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position.
- Check the size: the smaller neck is, on plenty of cars, the AdBlue one.
- Open the filler flap and look for a label — many cars mark what goes in each filler just there.
- Can't see it next to your diesel filler? In that case check beneath the bonnet or inside the boot — the handbook will say where.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on.
AdBlue top-ups that never reach the diesel tank
When the light goes on, wherever in Surrey, use this routine.
- Turn off once parked — level ground, motor off, and not rushed by High Street at the roadside.
- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Silly, perhaps, but it works.
- Both under a single flap? So make sure the cap on the diesel filler stays closed ahead of lifting the bottle.
- Finish when your tank is topped up or the bottle is empty; until then, pour gently through its own spout.
- Before you start the vehicle, close the cap and check a second time that your diesel cap never opened off.
Spot at step two or three that it has already gone into your diesel side? So stop just there. Stage five is out.
Already put AdBlue in your diesel tank in Weybridge?
Don't start the motor: that's how the short order of things starts. The fuel pump runs on plenty of diesels as soon as your ignition is switched on — so leave it off. Diluting it with more diesel fails, since AdBlue settles to the base instead of blending — and that's where your fuel is drawn from.
The staff at Shell, Tesco or another forecourt will normally help pushing the car away when asked. On your own drive around Weybridge? Then the car remains where it is.
If the motor has already run, stop as soon as it is safe and switch off. On the M3, under 3 miles from Weybridge, that means the next exit. Roughly how far did it go? Hopping across Weybridge is less work than a trip of under 25 miles towards Westminster, so say.
Our arrival in Weybridge, and what occurs next
Outside St Charles Borromeo Catholic Primary School, Weybridge, close to Clarenden Fine Art or on your own drive: wherever your car has stopped, our technicians come to it. The answers decide the work and the quote, so our technicians ask what got in, roughly how much, and if it's run. During the call itself, you hear the quote — ahead of anything else.
After that: draining, 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 doesn't wash out on its own — which is why the flush matters more here than with petrol. A test comes at the end: before that, clean diesel is added, and the fuel filter is cleaned or changed if necessary. The engine is started next and checked to be sure it runs properly, all before we go.
Most jobs are done in about half an hour after our technicians arrive, as long as your motor has not run — and the pumps our technicians use are safe on a live forecourt and quiet after dark beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, take a look at your insurance documents; many include cover for misfuelling.
