Avoiding AdBlue in a Diesel Tank in Corseford: Why It Happens

Why does AdBlue in a diesel car need its own filler?

Plenty of newer diesels in Millikenpark, like those in Corseford, carry on two liquids; the motor takes just the diesel. Your exhaust, not the motor, is where AdBlue goes: dosed into the gas to fresh them, from its own tank.

Different tanks, different fillers. Under one flap, next to each other: that's the arrangement on many motors. On others, AdBlue's filler sits beneath the bonnet or in the boot instead. Diesel gets filled on each filling station visit, again and again. The AdBlue side is filled far less regularly, usually from a bottle, and normally by someone who has to stop and think where it goes. It is in the gap that the mistake lives.

Corseford: how AdBlue in the diesel tank occurs

Carelessness seldom causes it. Instead is three things coming up together.

To start with, the warning. Low AdBlue triggers a message from the car, and letting it run out means limp mode — so a rushed top-up, maybe before work off Corseford Avenue, perhaps at The Spateston Inn on the way home that evening.

The old car's cap is where your hand reaches — yet a rental car, a new vehicle or a company car keeps the fillers somewhere else. That is a second factor: a new car.

A spouted bottle meets no resistance at a diesel filler any more than at an AdBlue one. So the pour, once begun, keeps on. Whether it occurs in Cartside or the middle of Corseford, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so check them before you pour anything, on a driveway in Tandlehill or a forecourt in Corseford.

  • Read the cap rather than going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps usually aren't.
  • On many motors, size gives it away: AdBlue has the smaller filler neck.
  • The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where.
  • In the boot or under the bonnet: that is where your filler is if it is not by your diesel cap, and the handbook tells you which.
  • The previous driver knows. Ask when you collect a hire car or fleet car — at Milliken Park's car park, say — not when the light comes on.

AdBlue top-ups that never reach your diesel tank

When the light comes on, wherever across Renfrewshire, use this routine.

  • Not in a rush on the side of Cochranemill Road, not on a slope, not with your motor running: park and switch off first.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Daft, perhaps, yet it works.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Finish once your tank fills or the bottle runs dry; before that, tip slowly using its own spout.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle.

Discover during the second or third stage that AdBlue went in the diesel tank? That is where you stop. Step five stays out.

Corseford: already put AdBlue in the diesel tank?

Brief list, then. Top of that: your motor stays off. The fuel pump runs on plenty of diesels the moment the ignition goes on — so keep it off. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from.

If you're on a forecourt, whether it's the Morrisons or the Esso, ask the attendants to help roll the vehicle clear of the petrol pump. Your own driveway in Corseford is where it should stay.

When your engine has run already, pull over safely then turn the car off. On the M8, under 5 miles from Corseford, that means the next exit. About how far did it go? Crossing Corseford is smaller a job than a trip of under 15 miles towards Glasgow, so tell us.

Corseford: what occurs when we turn up

We come to the car wherever it has stopped, whether that's outside the local primary school, close to Thomas Shanks Memorial Fountain or on your own drive. Which fluid got in, the quantity, and whether it ran: our technicians ask since those replies decide the work and price. No one sets off until you have heard the price over the phone.

Emptying your tank comes next, then a full flush of the system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. After your filter is cleaned — or replaced, if required — clean diesel goes in, and finally your car gets tested. Before we go, our engineers start the car and check that it's running correctly.

Most jobs are done in roughly half an hour once our technicians get there, provided the motor has not run — and the pumps we use are safe on a live forecourt yet quiet at night outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your policy as the van travels to you: misfuelling cover is included with plenty of policies.
