Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Haydon Wick
AdBlue already in the diesel tank? In that case set this page aside for now, keep the ignition and motor off, and ring 0333 366 0103. Usually, if the engine hasn't run, it is emptied and fully rinsed where the car is around Haydon Wick. Reading in advance? Then the rest covers why it comes about and what to stop it happening at all.
Why does AdBlue in a diesel vehicle need its own filler?
Many current diesels on the roads round Haydon Wick and Abbey Meads carry two liquids, not one. Diesel goes to the engine. Kept in a tank of its own, AdBlue is fed into your exhaust gas to clean it.
There is a filler on each tank. Many of cars share a single flap for the two, while others put the AdBlue filler to your boot or under the bonnet. Filling the diesel side at the petrol pump goes on constantly. Far less regularly, the AdBlue side gets filled — mostly from a bottle, by someone working out where it goes. That gap is where the slip lives.
How AdBlue in the diesel tank takes place around Haydon Wick
Three things tend to line up, and carelessness is seldom one of them.
Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a drive off Windflower Road, or heading home in the car park outside The Manor Farm.
New-to-you motors are second, as well. Rentals, new motors and company cars place their fillers in new places, and the hand goes for the cap used on the old one.
Lastly, the bottle goes in: a diesel filler or AdBlue one, it slides in just as easily, and after the tip starts, no part halts it. It takes a few seconds, whether out in Moredon or right in the centre of Haydon Wick.
The AdBlue filler and the diesel filler: telling them apart
Be it a Haydon Wick forecourt or a drive out in Blunsdon St Andrew, take a couple of seconds on these before any is poured in.
- Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits.
- On many vehicles, size tells: AdBlue gets the smaller filler neck.
- Look inside the fuel flap: many cars carry a label there saying which fuel goes where.
- In your boot or under the bonnet: that is where your filler sits if it's not by the diesel cap, and the handbook tells you which.
- The previous driver will know. Check as you pick up a rental or fleet car — at Swindon's car park, say — not once the light comes on.
Keeping AdBlue out of the diesel tank when you top up
On the day the warning appears — anywhere you are in Wiltshire — a simple routine to use.
- Turn off once parked — flat ground, motor off, and not in a rush by Thames Avenue on the verge.
- Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud as you unscrew it. It sounds silly. It works.
- Both behind a single flap? Then make sure the lid on the diesel side stays closed before raising the bottle.
- Gently is best, through the bottle's own spout, until it is full or the bottle runs out.
- Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car.
Find at step two or three that it has already gone into your diesel side? So stop right there. Stage five stays out.
Haydon Wick: already put AdBlue in the diesel tank?
Then the order of things is short. Don't start your engine. On many diesels the ignition alone runs the fuel pump, and so do not switch the car on. Filling up with diesel will not thin it: rather than mixing, AdBlue sinks to the base of your tank, right where fuel is taken from.
At a forecourt — Asda, BP or any other — the staff will normally help push the vehicle clear, if you ask. Your own driveway in Haydon Wick is where it should stay.
Stop as soon as it is safe and switch off, if your motor has already run. The next exit is the place to come off if you're on the M4, under 5 miles from Haydon Wick. Distance matters — a short hop across Haydon Wick makes a smaller job than heading under 50 miles towards Oxford — so say roughly how far it went.
Haydon Wick: what happens when our engineers turn up
Our technicians come to the vehicle wherever it has stopped, whether that is outside Haydonleigh Primary School, close to St John's Church or on your own driveway. The replies decide the work and our quote, so we ask what went in, roughly how much, and whether it has run. No one sets off until you have heard our quote over the phone.
Then the tank is drained and the fuel system flushed thoroughly. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither clears out by itself. That is why it counts more. A test is last: before that, fresh diesel goes in, and the filter is cleaned or replaced as needed. Your engine is fired up next and tested to be sure it runs properly, all before we leave.
If your motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. Nothing upfront; you settle up that day. Afterwards, the VAT invoice and the report from the engineer go to you for your insurer. Misfuelling cover is part of many insurance policies — and so use the wait to check yours.
