AdBlue in a Diesel Tank in Mulbarton: Why It Happens and How to Avoid It
AdBlue already in your diesel tank? In that case set this page down a moment, leave the ignition and motor off, and ring 0333 366 0103. Normally, when your engine has not turned, it's drained and thoroughly rinsed where your car sits in Mulbarton. The remainder of this page explains why it occurs and how to ensure it does not — handy if you're reading ahead of time.
AdBlue in a diesel motor: two tanks, two fillers
Diesel goes to your motor — yet plenty of current diesels seen about Mulbarton and East Carleton hold another fluid too. Stored in a tank of its own, AdBlue is sprayed into the exhaust gas to clean it.
Every tank comes with one filler of its own. Plenty of motors have a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet. At the pump, your diesel side is topped up constantly. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and far less frequently. That gap is where the error lives.
AdBlue in the diesel tank in Mulbarton: how it takes place
It is rarely carelessness. Three things tend to line up.
On a driveway off The Common before work, or in the car park at The Worlds End heading home: that is where the hurried top-up takes place. Why the rush? As AdBlue gets low the vehicle tells you, and if it's gone, limp mode kicks in.
Next, the hand reaches for the cap it knew on the old vehicle — since a rental car, a new motor or a company car puts the fillers somewhere your last one didn't.
Nothing halts the pour once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, whether in Bracon Ash or bang in the centre of Mulbarton.
How to tell the AdBlue filler from the diesel one
A few seconds is all these take — so check them before you pour anything, on a drive in Lower East Carleton or a forecourt in Mulbarton.
- Check the cap instead of going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel ones normally are not.
- On many cars, size tells: AdBlue gets the smaller filler neck.
- Open the filler flap and check for a label — many vehicles show which belongs in which inlet right there.
- In the boot or under the bonnet: that is where your filler sits if it is not by your diesel cap, and the handbook says which.
- Whoever had it before knows. Ask as you collect a rental or fleet car — at Wymondham's car park, say — rather than once the light comes on.
AdBlue top-ups that never reach the diesel tank
For the day the light comes on — wherever it is around Norfolk — a routine to use.
- Pull in somewhere level, motor off, with time in hand — never rushing on the side of Birchfield Lane.
- Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — once you've located your filler and read the cap.
- Both under a single flap? Then confirm the cap on your diesel side stays shut before raising the bottle.
- Slowly is best, through the bottle's own spout, till it's full or the bottle is empty.
- Only after that, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened.
Stop there if you find, at stage two or three, that you've already poured into your diesel side. Don't go on to step five.
Put AdBlue in your diesel tank around Mulbarton already?
Then the order of things is short. Don't start the motor. On many diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on. Diluting it with extra diesel won't work, because AdBlue sinks to the base instead of blending — and that is where your fuel is drawn from.
The attendants at Shell, Tesco or any forecourt will usually help to push your car away when asked. If you are on your own driveway around Mulbarton, leave the car where it sits.
If the engine has already run, stop as soon as it is safe and switch off. Mulbarton sits over 50 miles from the M11; there, take the next junction. About how far did it go? Crossing Mulbarton is smaller work than a trip of under 10 miles to Norwich, and so say.
What takes place when our technicians get there in Mulbarton
Our van comes to your car anywhere it stopped — your own driveway, near Saint Mary Magdalen, or by Mulbarton Primary School. Both the work and the quote depend on three answers — what fluid, which quantity, and if it has run — so we ask. That quote comes on the call, before any van leaves.
Next: a drain, then a full flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that counts more here than with petrol. Once the filter has been flushed — or renewed, if needed — clean diesel goes in, and then your car is tested. Your engine is fired up next and checked to make sure it runs properly, all before our technicians leave.
Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which your engine hasn't run take about half an hour once we are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your policy as the van travels to you: misfuelling cover comes with plenty of policies.

AdBlue drains across Norfolk, Mulbarton included
Throughout NR postcodes, the vans that cover Mulbarton — a rural village — work the nearby locations too, Swardeston and Hethel among them. Quickest of all: give a NR14 8 postcode to our van.
Your car stays put. We drain it where it is — a side street close to Mulbarton Village Sign, a lay-by on the way to Mulbarton FC, a driveway. If you're close to a boundary, or somewhere hard to describe like the back of Primitive Methodist Chapel, ring and ask rather than assuming.
For Mulbarton drivers, the short version
Tip nothing until you have read the cap. If AdBlue has gone in the diesel tank regardless, leave the car off and ring 0333 366 0103. Petrol in Diesel clears it where it sits, anywhere in Norfolk.
