AdBlue in a Diesel Tank in Cadder: How It Occurs and How to Stop It
If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and the ignition off and ring 0333 366 0103. Caught before the motor runs, it's normally a drain and a thorough flush, done where your car is in Cadder. Not happened yet? Further down, the rest of the page explains the why it takes place and the ways to prevent it for good.
AdBlue in a diesel motor: two tanks, two fillers
No single liquid but two: that is what many modern diesels near Cadder and Summerston run, with diesel for your motor. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.
Each tank has its own filler. Under one flap, side by side: that's the arrangement on a lot of motors. On others, AdBlue's filler is beneath the bonnet or in your boot instead. Topping up the diesel side at the pump happens all the time. Far less regularly, the AdBlue side gets filled — mostly from a bottle, by someone thinking about where it goes. That gap is where the error lives.
Cadder: how AdBlue in the diesel tank takes place
Three things tend to line up, and carelessness is rarely one of them.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Vaila Street before work, or in the car park outside The Inn on the way home.
Unfamiliar vehicles come second, as well. Rentals, new vehicles and company cars put their fillers in new places, and habit reaches for the cap used on the old one.
A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the tip, once begun, keeps on. The same few seconds decide it, in the middle of Cadder or out in Gilshochill.
The AdBlue filler and the diesel filler: telling them apart
Before you pour anything, whether on a driveway in High Possil or a forecourt around Cadder, check these. They take a couple of seconds.
- Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not where it sits.
- On many motors, the size tells: AdBlue gets the smaller filler neck.
- Open the flap and look for a label — many vehicles show what goes in which filler just there.
- The handbook shows where it lives when your filler isn't next to the diesel cap: your boot, or under the bonnet.
- Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Gilshochill.
How to top up without AdBlue in the diesel tank
Wherever around Glasgow City the light comes on, here is a routine for the day.
- Stop on level, engine off, with time to spare — never rushing on the side of Skirsa Street.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on.
- Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Only after that, start your car: close the cap, check a second time, and make sure the diesel cap was never opened.
If at step two or three you find you have already poured into your diesel side, stop there. Do not go on to step five.
Already put AdBlue in your diesel tank around Cadder?
What follows is a short order of things, beginning with not starting the engine. Keep the ignition off too, because on many diesels switching it on by itself runs the fuel pump. Topping up with diesel will not weaken it: rather than mixing, AdBlue sinks to the bottom of that tank, just where fuel is drawn from.
If you're at a forecourt, whether it is the BP or the Esso, ask the attendants to help roll the vehicle away from the petrol pump. At home in Cadder? Then the vehicle stays put.
Stop as soon as it is safe then switch off, if your engine has already run. The next exit is where to leave when you are on the M8, under 3 miles from Cadder. Tell us roughly how far it went: a run towards Glasgow, under 3 miles away, is a bigger job than a short hop across Cadder.
Our arrival in Cadder, and what occurs next
Our engineers come to the vehicle wherever it has stopped, whether that is outside the local primary school, near Cadder Pit Disaster Memorial or on your own drive. Our technicians ask what got in, about how much, and if it has run, because those answers determine the work and our price. During the call itself, you hear our price — before dispatch.
Emptying the tank comes next, followed by a full flush of the system. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither clears out by itself. That is why it matters more. A test comes at the end: before that, fresh diesel is added, and the fuel filter is cleaned or changed as needed. We don't leave until it has been fired up and is running smoothly.
Unstarted vehicles usually need a half-hour visit after the moment we arrive. The kit is safe on a busy 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 included in plenty of insurance policies — so use the wait to check yours.
