Avoiding AdBlue in a Diesel Tank in Glyncorrwg: Why It Occurs
Keep your engine and ignition off and ring 0333 366 0103 now — the rest can wait if AdBlue is already in the diesel tank. Caught before the motor runs, it is usually a drain and a thorough flush, done where the vehicle is around Glyncorrwg. The rest of this page covers why it happens and how to make sure it doesn't — useful if you are reading before it has happened.
AdBlue in a diesel motor, and its separate tank
Diesel goes to your engine — yet plenty of newer diesels driven round Glyncorrwg and Abercregan carry a second liquid too. Stored in a tank of its own, AdBlue is sprayed into your exhaust gas and cleans it.
There is a filler for each tank. Other cars keep the AdBlue filler in the boot or under the bonnet; a lot of others place both side by side behind one flap. At the petrol pump, the diesel side gets filled constantly. The AdBlue side is filled far less commonly, normally from a bottle, and normally by someone who has to stop and think where it goes. Mistakes happen in the gap between the two.
AdBlue in the diesel tank around Glyncorrwg: how it takes place
Three things tend to come together, and carelessness is seldom one of them.
On a driveway off Commercial Street before work, or in the car park at the pub in the village heading home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low the car tells you, and once it is empty, limp mode kicks in.
Then, the hand reaches for the cap it would have used on the old motor — because a hire car, a new car or a company car puts the fillers somewhere your last one didn't.
Third, the bottle fits: diesel filler or AdBlue one, it goes in as easily, and once the pour starts, no part halts it. It takes a few seconds, be it out in Blaengwynfi or bang in the heart of Glyncorrwg.
The AdBlue filler and your diesel filler: telling them apart
Whether a Glyncorrwg forecourt or a drive out in Croeserw, spend a few seconds over these before anything goes in.
- Where it sits can mislead; the cap does not. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel ones normally don't.
- On many motors, size tells: AdBlue gets the smaller filler neck.
- A label inside the fuel flap frequently says which fuel goes where, on many motors. Look for it.
- The handbook. If the filler isn't by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.
- Whoever had it before knows. Check as you pick up a hire car or company car — at Treherbert's car park, perhaps — not once the warning comes on.
Keeping AdBlue out of your diesel tank when you top up
Wherever around Neath Port Talbot the light comes on, here is a routine for that day.
- Stop on level, motor off, with time to spare — never rushing on the side of Castle Street.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, perhaps, but it works.
- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Close the cap, and look again — making sure your diesel filler remained shut the whole time. Only then, start the car.
If at step two or three you find you have already poured into your diesel side, stop there. Never go on to step five.
Glyncorrwg: already put AdBlue in the diesel tank?
Brief order, then. First: your motor remains off. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the car on. Filling up with diesel will not dilute it: instead, AdBlue sinks to the bottom of your tank, right where the fuel is drawn from.
If you are at a forecourt, whether it's the Texaco or the Esso, ask the attendants to help push the vehicle away from the pump. If you are on your own driveway around Glyncorrwg, leave the vehicle where it stands.
If the engine has already run, stop as soon as it is safe and switch off. Glyncorrwg lies under 10 miles from the M4; on it, take the first exit. Tell us roughly how far it went: a run towards Swansea, under 15 miles away, is a bigger job than a short hop across Glyncorrwg.
When our engineers turn up in Glyncorrwg, what occurs?
By the local primary school, near Peregine Ridge or on your own driveway: wherever the car has stopped, our engineers come to it. What fluid went in, the amount, and if it ran: we ask since those answers decide both work and quote. That price is given on the call, ahead of any van leaving.
Draining your tank comes next, followed by a full flush of the fuel system. More than with petrol, it matters here: crystals form, certain metals corrode, and none of that clears out on its own, no matter how long it is left. A test comes at the end: before that, fresh diesel goes in, and the filter is cleaned or replaced if necessary. Before leaving, our technicians fire it up and confirm that it's running properly.
With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where your engine hasn't run need about half an hour once our technicians are there. Payment happens on the day, not upfront, and you receive the paperwork an insurer wants: an engineer's report and a VAT invoice. It is worth looking at your policy as the van travels to you: misfuelling cover comes with many policies.
