Avoiding AdBlue in a Diesel Tank in Trevarrack: Why It Happens
Keep the motor and ignition off and phone 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. A drain and a thorough flush, done just where the vehicle stands around Trevarrack, is normally what it takes when caught before your motor runs. Nothing happened yet? Further down, the rest of the page explains the why it takes place and the how to prevent it altogether.
AdBlue in a diesel vehicle, and its separate tank
Plenty of current diesels on the roads around Trevarrack and Treneere carry two liquids, not one. Diesel goes to the motor. Its own tank keeps it, and from there it is sent to the exhaust, and there spraying cleans the gas.
Each tank has its own filler. Plenty of motors share a single flap for the two, whereas some move the AdBlue filler to your boot or under the bonnet. The diesel side is fuelled at the pump all the time. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less commonly. Mistakes happen in that gap between the two.
How AdBlue in your diesel tank takes place in Trevarrack
It's hardly ever carelessness. Three things tend to line up.
Hurry comes from the warning. The vehicle tells you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off B3311, or on the way home in the car park at The Coldstreamer.
The old car's cap is where your hand reaches — yet a hire car, a new motor or a company car keeps the fillers somewhere else. That is a second thing: an unfamiliar motor.
No part halts the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it occurs in Trythogga or the middle of Trevarrack, it is the same few seconds.
How to tell the AdBlue filler from the diesel one
Look at these first, at a forecourt in Trevarrack or a driveway over in Penzance. A few seconds, that's all.
- Check the cap rather than going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps usually are not.
- On plenty of cars, the size gives it away: AdBlue has the smaller filler neck.
- Look inside the fuel flap: many vehicles have a label there saying which fuel goes where.
- Can't find it next to the diesel filler? Then check beneath the bonnet or inside the boot — the owner's manual says where.
- Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Penzance.
Topping up AdBlue without it reaching the diesel tank
A routine for the day the light comes on, wherever across Cornwall that is.
- Pull in on level, motor off, with time in hand — not rushing on the side of School Lane.
- Silly as it sounds, saying "AdBlue" aloud as you unscrew the cap does the trick — once you have located your filler and read it.
- Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Stop once that tank fills or the bottle runs dry; until then, pour gently through the own spout.
- Shut the cap, and check again — making sure your diesel cap stayed shut the whole time. Only then, start the vehicle.
Find at step two or three that it's already gone into your diesel side? Then stop right there. Do not go on to stage five.
Put AdBlue in the diesel tank around Trevarrack already?
The short order of things, starting with no starting the motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is pulled from — so do not top up with diesel to thin it.
If you're on a forecourt, whether it's the Tesco or the Sainsbury's, ask the staff to help push the car clear of the petrol pump. Leave it where it is if you're on your own drive around Trevarrack.
Where the engine has run already, pull over safely then switch the car off. Trevarrack sits over 50 miles from the M5; on it, take the first exit. About how far did it go? Crossing Trevarrack is less a job than a trip of under 25 miles towards Truro, and so tell us.
Trevarrack: what happens when our engineers arrive
The van reaches the vehicle wherever it has come to rest — your own driveway, near Gulval Village Hall, or by Gulval School. The replies settle this work and our quote, and so our engineers ask what went in, about how much, and whether it has run. On the call itself, you are told our price — ahead of dispatch.
Then that tank is drained and your system purged thoroughly. More than with petrol, it counts with AdBlue: the crystals build up, some metals corrode, and nothing clears away unaided, however long it sits. A test comes last: before that, clean diesel is added, and the fuel filter is flushed or replaced as needed. We don't go until it has been fired up and is running correctly.
Unstarted vehicles mostly mean a half-hour job after the moment we arrive. The kit is fine on a live forecourt, and quiet enough for a driveway late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is part of many insurance policies — and so make use of the wait to look at yours.

Shifting the car is not needed. The drain takes place on the spot, whether a drive, a street by St Gulval, or a lay-by on the way to Princess May recreation ground. Assuming won't help at the back of St John the Baptist, on a border, or somewhere awkward to pin down; ring and ask.
