How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Treninnick
AdBlue already in the diesel tank? Then set this page aside a moment, leave the ignition and motor off, then phone 0333 366 0103. Caught before your engine runs, it's normally a drain and a thorough flush, done where your car is in Treninnick. Nothing happened yet? Below, the page covers the why it occurs and the how to prevent it for good.
Two fillers, two tanks: AdBlue in a diesel vehicle
No single liquid but two: that is how many newer diesels around Treninnick and Lane carry, with diesel for your motor. Kept in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.
There's a filler on every tank. Plenty of motors have a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet. Diesel gets filled on every forecourt visit, again and again. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less regularly. The mistake grows in that gap between them.
Treninnick: how AdBlue in your diesel tank occurs
It is seldom carelessness. Three things tend to line up.
Hurry comes from the warning. Your car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Treloggan Road, or on the way home in the car park outside The Lanherne Pub & Restaurant.
Next, the hand reaches for the cap it knew on the old vehicle — since a rental car, a new car or a company car places the fillers where your last one didn't.
Third, the bottle goes in: a diesel filler or AdBlue filler, it slides in as easily, and after the tip starts, nothing halts it. It takes seconds, be it out in Trenance or right in the centre of Treninnick.
Telling the AdBlue filler from your diesel filler
Whether a Treninnick forecourt or a driveway over in Newquay, spend a couple of seconds on these before anything is poured in.
- Where it sits can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel caps usually do not.
- Many vehicles fit AdBlue the smaller neck of the two.
- The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where.
- Can't see it beside your diesel inlet? In that case check below the bonnet or in the boot — the handbook says which.
- The person who drove the car last. On a hire or company car collected from somewhere like the car park at Newquay, ask before you leave, not when the light comes on.
How to top up without AdBlue in the diesel tank
On the day the light comes on — wherever you are in Cornwall — a simple routine to follow.
- Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Mellanvrane Lane.
- Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — after you've found your filler and read the cap.
- Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Slowly does it, through the bottle's own spout, till it's full or the bottle runs out.
- Before you start your car, close the cap and look a second time that your diesel cap never opened off.
Spot at step two or three that it's already gone into your diesel side? Then stop right there. Do not go on to step five.
Put AdBlue in your diesel tank around Treninnick already?
Don't start the motor: that is where the short order of things begins. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with more diesel fails, since AdBlue settles to the base rather than mixing — and that is where the fuel is drawn from.
Ask the attendants to help push the car away from the pump if you're on a forecourt — the Texaco, the Esso or somewhere else. On your own drive around Treninnick? Then the vehicle remains put.
Already started? Stop when it is safe, then turn off. The next junction is the place to leave if you're on the M5, over 50 miles from Treninnick. A short hop across Treninnick is a smaller job than a run towards Truro, under 10 miles away, and so tell us roughly how far it went.
Our arrival in Treninnick, and what occurs next
By The Bishops CofE Learning Academy, near Atlantic Centre or on your own driveway: wherever your car has stopped, our technicians come to it. What fluid was put in, the quantity, and if it ran: we ask because the answers set the work and price. You hear that price on the phone, before anyone sets off.
Emptying the tank comes next, then a thorough flush of the system. Much more than with petrol, it matters with AdBlue: the crystals form, some metals corrode, and nothing clears away on its own, however long it is left. The filter flushed or, where needed, replaced; clean diesel in; then a check of your car. Before we go, our technicians start it and make sure that it is running smoothly.
Unrun cars mostly need a half-hour visit from arrival. The kit is fine on a busy filling station, and quiet enough for a residential street after dark. No money in advance; 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 plenty of insurance policies — and so use the wait to check yours.
