Avoiding AdBlue in a Diesel Tank in Aynho: Why It Occurs
Leave the motor and ignition off and ring 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. A drain and a thorough flush, carried out right where your car stands in Aynho, is normally what it needs when caught before your motor runs. Here in advance? In that case what follows covers why it comes about and how to stop it happening at all.
Two fillers, two tanks: AdBlue in a diesel motor
Plenty of current diesels on the roads round Aynho and Croughton carry two liquids, not one. Diesel goes to your engine. Your exhaust, not your motor, is where AdBlue goes: dosed into the gas to fresh them, from a separate tank.
Every tank comes with a filler of its own. Plenty of cars have a single flap for the two, while others move the AdBlue filler to your boot or under the bonnet. Topping up your diesel side at the pump goes on constantly. The AdBlue side is topped up far less frequently, usually from a bottle, and normally by someone who has to stop and think where it goes. That gap is where the error lives.
How AdBlue in the diesel tank occurs in Aynho
Carelessness rarely causes it. Instead is three things lining up together.
Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a drive off The Butts, or on the way home in the car park outside the pub in the village.
Unfamiliar motors are second, too. Hire cars, new motors and company vehicles place their fillers differently, and habit goes for the cap it used on the old one.
Nothing stops the pour once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it happens in Walton Grounds or the middle of Aynho, it's the same few seconds.
Which filler is for AdBlue, and which for diesel?
Whether a Aynho forecourt or a drive out in Astrop, take a few seconds on these before any goes in.
- Check the cap instead of going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones normally aren't.
- Check the size: the smaller neck is, on plenty of cars, the AdBlue one.
- Look inside your fuel flap: plenty of cars carry a label there saying which fuel goes where.
- The handbook says where it lives if your filler isn't next to your diesel cap: your boot, or under the bonnet.
- Whoever had it before will know. Ask as you collect a rental or company car — at Kings Sutton's car park, say — not once the light comes on.
How to top up without AdBlue in your diesel tank
The day the light goes on, anywhere across Northamptonshire, follow this routine.
- Stop somewhere level, motor off, with time in hand — not hurried on the side of Charlton Road.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
- The diesel cap remains on. When the two sit under a flap, confirm it is shut before lifting the bottle.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Close the cap, then check once more — making sure the diesel cap stayed closed throughout. After that, start the vehicle.
Discover at the second or third step that AdBlue went into the diesel tank? That is where you stop. Do not go on to step five.
AdBlue in the diesel tank already, in Aynho?
Then the order of things is short. Do not start your engine. Keep the ignition off too, since on plenty of diesels it alone starts your fuel pump. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.
On a forecourt — A E Prentice, Esso or any other — the staff will usually help push the vehicle away, if you ask. If you're on your own driveway around Aynho, leave the car where it sits.
Stop as soon as it is safe then switch off, if the engine has already run. The next exit is the place to come off if you're on the M40, under a mile from Aynho. Tell us about how far it went: a run towards Oxford, under 25 miles away, is a bigger job than a short hop across Aynho.
What takes place when our technicians get there around Aynho
We come to your car wherever it has stopped, whether that is outside Croughton All Saints CofE Primary School, close to Aynho Village Hall or on your own drive. Those replies decide this work and our price, so we ask what was put in, about how much, and if it has run. That quote is given on the call, ahead of any van leaving.
The system is then flushed thoroughly, once your tank is cleared. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. The filter flushed or, where it must be, replaced; fresh diesel in; and then a test of your vehicle. We do not leave until it has been fired up and is running correctly.
Unrun cars usually mean a half-hour job from the moment we arrive. The kit is safe on a busy forecourt, and hushed enough for a driveway after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is part of many insurance policies — and so use the wait to check yours.
