Avoiding AdBlue in a Diesel Tank in Mornick: Why It Occurs
Keep the motor and ignition off then call 0333 366 0103 first — reading can wait if AdBlue is already in your diesel tank. In Mornick, catching it before your motor runs usually leaves a drain and a full flush on the spot. Not happened yet? Below, the page covers the reasons it occurs and the ways to prevent it for good.
AdBlue in a diesel motor, and its separate tank
Diesel goes to your motor — yet many modern diesels seen around Mornick and Golberdon carry another liquid too. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.
There is a filler on each tank. Other cars put the AdBlue filler in the boot or under the bonnet; a lot of others have the two side by side behind one flap. At the petrol pump, your diesel side gets filled constantly. Far less regularly, the AdBlue side gets filled — mostly from a bottle, by a person working out where it goes. It is in that gap that the error happens.
How does AdBlue in the diesel tank occur in Mornick?
It is rarely carelessness. Three things tend to line up.
Hurry comes 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 South Hill Road, or on the way home in the car park outside the pub in the village.
Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one.
A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. So the pour, after begun, keeps on. Whether it occurs in South Hill or the middle of Mornick, it is the same few seconds.
Telling the AdBlue filler from the diesel filler
A few seconds is all the checks take — so run through them before you pour anything, on a driveway in Plushabridge or a forecourt in Mornick.
- Position misleads; the cap does not. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel caps usually do not.
- Many vehicles fit AdBlue the smaller filler of the two.
- Look inside your fuel flap: plenty of vehicles have a label there showing which fuel goes where.
- The handbook. If your filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.
- The previous driver will know. Ask as you collect a hire car or company car — at Gunnislake's car park, say — not once the light appears.
Keeping AdBlue out of the diesel tank when you top up
Wherever in Cornwall the light comes on, this is a routine for the day.
- Not in a rush on the side of Stoke Road, not on a slope, not with the engine running: park then switch off first.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
- Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Close the cap, and check once more — confirm the diesel cap remained shut the whole time. After that, start the car.
Stop there if you find, at stage two or three, that you have already poured into your diesel side. Step five stays off limits.
Already put AdBlue in the diesel tank in Mornick?
Do not start the motor: that is how the short order of things begins. On many diesels the ignition alone runs the fuel pump, and so don't switch the car on. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so do not top up with diesel to thin it.
Ask the staff to help roll the car clear of the pump if you're on a forecourt — the Tesco, the another forecourt nearby or anywhere else. Your own drive around Mornick is where it should stay.
Where the motor has run already, stop somewhere safe then switch the car off. Mornick lies under 50 miles from the M5; there, use the first junction. Tell us roughly how far it went: a run towards Plymouth, under 15 miles away, is a bigger job than a short hop across Mornick.
Our arrival in Mornick, and what happens next
Outside Pensilva Primary School, close to St Sampson or on your own driveway: wherever the car has stopped, our engineers come to it. Our engineers ask what was put in, about how much, and whether it has run, because the answers determine the work and our quote. The price comes over the phone, ahead of any van leaving.
The fuel system is then purged thoroughly, once that tank is drained. With AdBlue that matters 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 cleaned or, where needed, swapped; clean diesel in; and then a test of your car. Before we leave, our engineers fire it up and check that it's running smoothly.
Most jobs are done in about half an hour after our engineers arrive, provided the motor hasn't run — and the pumps our engineers use are fine on a busy forecourt yet quiet after dark outside a house. Nothing in advance; you settle up that day. Afterwards, the VAT invoice and a report from the engineer are handed to you for the insurer. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.

The vehicle stays put. A drive, a lay-by on the way to Stockaton Wood, a side street near St Melor: our engineers drain the car where it is. If you're close to a boundary, or somewhere hard to explain like the back of South Hill Parish Hall, ring and ask rather than assuming.
Mornick motorists: the short version
Always, the cap; after that, the pour. If AdBlue has gone in the diesel tank all the same, leave the vehicle off and call 0333 366 0103. Petrol in Diesel clears it where it waits, anywhere around Cornwall.
