Gartlea: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
Keep your engine and ignition off and ring 0333 366 0103 first — reading can wait when AdBlue is already in your diesel tank. In Gartlea, finding it before the motor runs usually means draining and a full flush on the spot. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it doesn't.
Why does AdBlue in a diesel motor need its own filler?
Plenty of newer diesels around Craigneuk, like those in Gartlea, carry on two fluids; the motor takes just the diesel. Your exhaust, not the engine, is where AdBlue goes: sprayed into the gas to clean it, from its own tank.
Each tank comes with a filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Topping up the diesel side at the petrol pump goes on constantly. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less regularly. The mistake lives in that gap.
Gartlea: how AdBlue in your diesel tank occurs
It's hardly ever carelessness. Three things tend to line up.
First, the warning. Low AdBlue brings a message from the vehicle, and letting it run dry means limp mode — hence a rushed top-up, perhaps before work off Lady Wilson Street, perhaps outside Albert Bar on the way home that evening.
The old car's cap is where the hand reaches — but a rental car, a new car or a company car keeps the fillers elsewhere. That is the second thing: an unfamiliar vehicle.
A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. So the pour, after started, keeps on. Airdrie or the middle of Gartlea: it takes the same few seconds in both.
How to tell the AdBlue filler from the diesel one
Before you pour anything, whether on a driveway in Drumgelloch or a forecourt around Gartlea, check these. They take a few seconds.
- Read the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones normally are not.
- Many vehicles fit AdBlue the smaller filler of the two.
- Look inside your fuel flap: many vehicles carry a label there saying which fuel goes where.
- The handbook shows which it lives if your filler is not next to the diesel cap: your boot, or under the bonnet.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Airdrie, ask before you leave, not when the light comes on.
Keeping AdBlue out of the diesel tank when you top up
On the day the warning comes on — anywhere you are in North Lanarkshire — a routine to follow.
- Turn off after you park — flat ground, motor stopped, and never rushed by Gartlea Road on the verge.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, perhaps, but it works.
- The diesel cap stays on. When both share a flap, confirm it is closed before the bottle comes up.
- Finish when the tank is topped up or the bottle is empty; before that, pour slowly through its built-in spout.
- Before you start the car, shut the cap and look a second time that the diesel cap was never came off.
If at stage two or three you find you have already poured into your diesel side, stop there. Leave out stage five entirely.
Already put AdBlue in the diesel tank in Gartlea?
Brief list, then. Top of it: the motor remains off. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where your fuel is drawn from.
The attendants at Morrisons, BP or any forecourt will usually lend a hand pushing the car away if you ask. If you are on your own drive in Gartlea, leave the vehicle where it sits.
Already started? Pull over once it's sensible, then turn off. On the M8, under 3 miles from Gartlea, that means the next exit. Tell us about how far it went: a run towards Glasgow, under 15 miles away, is a bigger job than a short hop across Gartlea.
When we turn up around Gartlea, what happens?
Our van comes to the vehicle anywhere it stopped — your own drive, near Gartlea Community Centre, or outside the local primary school. The answers decide the work and our price, and so our technicians ask what got in, about how much, and if it's run. On the phone call itself, you hear our quote — ahead of dispatch.
Next: a drain, then a thorough flush of the whole system. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of that clears away by itself. That is why it counts more. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. We don't leave until it has been started and is running smoothly.
If your engine hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. 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 plenty of insurance policies — so use the wait to check yours.
