How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Whitlawburn
Stop here for a moment if the diesel tank already has AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain and a thorough flush, carried out just where your car sits around Whitlawburn, is usually what it needs when found before your motor runs. The rest of this page covers why it occurs and how to make sure it doesn't — useful if you're reading before it has happened.
Two fillers, two tanks: AdBlue in a diesel vehicle
Plenty of newer diesels around High Burnside, like those in Whitlawburn, carry on two fluids; your engine gets only your diesel. Your exhaust, not the motor, is where AdBlue ends up: dosed into the gas to clean it, from its own tank.
Every tank comes with a filler of its own. Other vehicles put the AdBlue filler in your boot or under the bonnet; plenty of others place the two side by side under one flap. At the petrol pump, the diesel side is topped up all the time. Far less commonly, the AdBlue side gets filled — mostly from a bottle, by someone working out where it goes. The slip lives in that gap.
How AdBlue in the diesel tank takes place in Whitlawburn
It is seldom carelessness. Three things tend to line up.
On a driveway off Whitlawburn Road before work, or in the car park at The Lawburn on the way home: that is where the hurried top-up takes place. Why the rush? As AdBlue runs low the vehicle warns you, and once it is gone, limp mode kicks in.
The old car's cap is where your hand reaches — but a hire car, a new car or a company car puts the fillers somewhere else. That is the second thing: a strange motor.
Third, the bottle fits: diesel filler or AdBlue one, it goes in as readily, and once the pour begins, no part stops it. Whether it happens in Springhall or the middle of Whitlawburn, it's the same few seconds.
Telling the AdBlue filler from the diesel filler
Whether a Whitlawburn forecourt or a drive over in Vicarland, take a couple of seconds on these before any is poured in.
- Read the cap rather than going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel ones normally are not.
- Plenty of vehicles fit AdBlue the smaller neck of the two.
- The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where.
- The handbook says which it lives when 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 collected from somewhere like the car park at Kirkhill, ask before you leave, not when the light comes on.
AdBlue top-ups that never reach your diesel tank
When the light goes on, anywhere across South Lanarkshire, follow this routine.
- Switch off once parked — level ground, engine stopped, and never in a rush beside Jenkins Court on the verge.
- 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 your 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, tip slowly — and stop when it is full or the bottle is empty.
- Before starting the car, close the cap and look again that your diesel cap never opened off.
Spot at step two or three that it's already gone into your diesel side? Then stop just there. Don't go on to step five.
Already put AdBlue in the diesel tank around Whitlawburn?
Do not start the engine: that's how the short order of things starts. The fuel pump runs on plenty of diesels the moment the ignition goes on — and so keep it off. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is drawn from — so do not top up with diesel to dilute it.
Ask the staff to help push your car away from the pump if you are on a forecourt — the Esso, the Morrisons or somewhere else. On your own drive in Whitlawburn? So the car stays where it is.
When your engine has been run by now, pull over somewhere safe then switch the vehicle off. On the M74, under 3 miles from Whitlawburn, that means the next junction. A short hop across Whitlawburn is a smaller job than a run towards Glasgow, under 5 miles away, so tell us roughly how far it went.
Whitlawburn: what occurs when our technicians arrive
We come to the vehicle wherever it has stopped, whether that is outside the local primary school, near Whitlawburn Community Resource Centre or on your own drive. Both the work and our price depend on three answers — which liquid, which amount, and whether it's run — so we ask. No one sets off until you have had the price over the phone.
Next: draining, then a full flush of the whole system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush counts more here than with petrol. A test is at the end: before that, clean diesel is added, and your filter is cleaned or replaced if necessary. Before we leave, we fire it up and check that it is running properly.
Unstarted vehicles mostly mean a half-hour visit from the moment we arrive. The kit is fine on a busy forecourt, and hushed enough for a residential street after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Before we get there, take a look at your insurance documents; many include cover for misfuelling.
