Bontuchaf: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and your ignition off then ring 0333 366 0103. Caught before your engine runs, it is generally a drain and a thorough flush, done where the car is around Bontuchaf. Here before the event? In that case what follows explains why it happens and what to prevent it ever happening.
Two fillers, two tanks: AdBlue in a diesel vehicle
Plenty of newer diesels in Pant, as well as Bontuchaf, carry on two liquids; your motor gets just your diesel. The exhaust, not the engine, is where AdBlue ends up: sprayed into the fumes to fresh it, from its own tank.
Every tank comes with a filler of its own. Many of motors share a single flap for the two, while some move the AdBlue filler to the boot or under the bonnet. At the petrol pump, the diesel side is topped up all the time. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and much less often. It's in the gap that the mistake happens.
AdBlue in your diesel tank around Bontuchaf: how it happens
It is hardly ever carelessness. Three things tend to line up.
On a drive off Long Street before work, or in the car park at Douglas Arms heading home: that is where the hurried top-up happens. What is the reason for the rush? As AdBlue gets low the car warns you, and once it's empty, limp mode kicks in.
Unfamiliar cars come second, as well. Rentals, new cars and company cars put their fillers in new places, and habit reaches for the cap it used on the old one.
A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the tip, once started, carries on. Gerlan or the heart of Bontuchaf: it is the same few seconds either way.
Telling the AdBlue filler from your diesel filler
Before you pour anything, whether on a driveway in Gwernydd or a forecourt in Bontuchaf, check these. They take a few seconds.
- Check the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually are not.
- Many vehicles fit AdBlue the smaller neck of the two.
- Lift the filler flap and check for a label — plenty of vehicles mark what belongs in each inlet right there.
- Cannot see it beside the diesel filler? Then look below the bonnet or inside your boot — the owner's manual says where.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Bangor (Gwynedd), ask before you leave, not when the light comes on.
AdBlue top-ups that never reach your diesel tank
A routine for the day the light comes on, wherever across Gwynedd that is.
- Switch off once parked — level ground, motor off, and never in a rush beside Ciltrefnus 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.
- The diesel cap remains on. Where the two sit under a flap, make sure it's shut before the bottle comes up.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Before you start your car, shut the cap and look a second time that the diesel cap never came off.
Find at stage two or three that it's already gone into your diesel side? So stop just there. Skip step five altogether.
AdBlue in your diesel tank already, in Bontuchaf?
Then the order of things is short. Do not start your engine. Keep your ignition off as well, because on plenty of diesels it alone starts the fuel pump. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is sucked from.
Ask the staff to help roll the car clear of the pump if you are at a forecourt — the EG Garages, the Calor or anywhere else. If you are on your own drive in Bontuchaf, leave it where it is.
Stop as soon as it is safe then switch off, if your motor has already run. On the Moreton Spur, under 50 miles from Bontuchaf, that means the next junction. Tell us about how far it went: a run towards Bangor, under 5 miles away, is a bigger job than a short hop across Bontuchaf.
Bontuchaf: what happens when our engineers turn up
Anywhere the vehicle came to rest, be it by the local primary school, near Christ Church or on your own drive, our van comes to it. Both the work and the price depend on three replies — what liquid, what quantity, and whether it has run — so we ask. Nobody sets off until you have had our price by phone.
Draining the tank comes next, then a thorough flush of your system. Much more than with petrol, it matters here: the crystals form, certain metals are attacked, and none of that washes out unaided, however long it sits. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. After that our technicians start the engine and make sure it runs properly before we go.
Unstarted vehicles mostly mean a half-hour visit from arrival. The kit is safe on a live forecourt, and quiet enough for a driveway after dark. Paying is on the day, not upfront, and you are given the documents an insurer asks for: an engineer's report and a VAT invoice. While we travel, have a look at your insurance documents; plenty carry cover for misfuelling.
