AdBlue in a Diesel Tank in Johnstown: Why It Occurs and How to Avoid It
AdBlue already in the diesel tank? In that case put this page down for now, keep the ignition and motor off, and phone 0333 366 0103. Normally, if your motor hasn't run, it is emptied and thoroughly purged where the car sits in Johnstown. Here in advance? Then what follows covers why it happens and how to stop it ever happening.
Two fillers, two tanks: AdBlue in a diesel motor
Diesel goes to your engine — but plenty of modern diesels driven round Johnstown and Rhosllannerchrugog carry another fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Each tank has its own filler. Under one flap, side by side: that's the arrangement on many vehicles. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead. At the pump, your diesel side gets filled constantly. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less frequently. The mistake grows in that gap between the two.
AdBlue in your diesel tank in Johnstown: how it happens
Three things tend to come together, and carelessness is rarely one of them.
Hurry comes from the warning. The vehicle tells you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done quickly, before work on a driveway off Laurel Grove, or on the way home in the car park outside The New Inn.
Then your car is strange. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have used on the old one.
Lastly, the spout fits: a diesel filler or AdBlue filler, it slides in just as readily, and after the tip starts, no part stops it. Ponciau or the heart of Johnstown: it is the same few seconds either way.
Telling the AdBlue filler from your diesel filler
Whether a Johnstown forecourt or a drive over in Afon Eitha, take a few seconds on these before anything is poured in.
- Where it sits misleads; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel ones normally do not.
- The size. On many motors the AdBlue filler neck is the smaller of the two.
- Check inside your fuel flap: many motors have a label there showing which fuel goes where.
- The handbook says which it is if your filler is not next to your diesel cap: your boot, or under the bonnet.
- The person who drove it last. On a hire or company car collected from somewhere like the car park outside Ruabon, ask before you leave, not when the light comes on.
Topping up AdBlue without it reaching the diesel tank
A routine for the day the light comes on, wherever across Wrexham that is.
- Switch off once parked — level ground, motor stopped, and never in a rush by Bryn Avenue at the roadside.
- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, yes, but it does the trick.
- Both behind one flap? So confirm the cap on the diesel side stays closed ahead of raising the bottle.
- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
- Close the cap, then check once more — confirm your diesel cap remained closed the whole time. After that, start your car.
Discover during the second or third step that the bottle went in the diesel filler? That is where you stop. Do not go on to step five.
Johnstown: already put AdBlue in your diesel tank?
Then the order of things is short. Don't start your engine. On many diesels your ignition alone runs the fuel pump, so do not switch the car on. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from.
Ask the attendants to help push the car clear of the pump if you are on a forecourt — the BP, the Esso or anywhere else. On your own drive around Johnstown? Then the car remains where it is.
When the engine has been run by now, pull over safely and turn the car off. Come off the M53 — under 25 miles out of Johnstown — at the first exit. A short hop across Johnstown is a smaller job than a run towards Wrexham, under 5 miles away, and so tell us roughly how far it went.
What occurs when our technicians arrive in Johnstown
We come to the vehicle wherever it has stopped, whether that's outside the local primary school, near St Mary, Church In Wales or on your own driveway. We ask what went in, about how much, and if it's run, because the answers decide this work and our price. That price comes on the call, ahead of any van leaving.
Emptying your tank comes next, then a full flush of the system. More than with petrol, it matters here: crystals build up, some metals corrode, and nothing washes out on its own, no matter how long it sits. Filter cleaned or, where needed, replaced; clean diesel in; then a test of your vehicle. Before we go, our engineers fire it up and confirm that it's running correctly.
Most jobs are finished in roughly half an hour after our engineers get there, as long as the motor hasn't run — and the pumps we use are safe on a live forecourt and quiet after dark outside a house. Your insurer will ask for an engineer's report and the VAT invoice, and both are yours once this job is done. Payment is on the day, with no deposit. It's worth looking at your policy while we travel to you: misfuelling cover is included with many policies.
