Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Kings Hill
Pause reading for a moment if your diesel tank already has AdBlue in it: ignition off, engine off, and ring 0333 366 0103. Usually, when the motor has not turned, it is emptied and thoroughly flushed where the vehicle is around Kings Hill. The remainder of this page covers why it takes place and how to ensure it doesn't — useful if you are reading before it has happened.
Why does AdBlue in a diesel car need its own filler?
Not one fluid but two: that is how many newer diesels around Kings Hill and Preston carry, with diesel for the motor. Your exhaust, not the engine, is where AdBlue goes: sprayed into the fumes to fresh it, from a separate tank.
Every tank has a filler of its own. Many of motors share a single flap for the two, whereas others move the AdBlue filler to the boot or under the bonnet. Diesel goes in at every forecourt call-out, week in, week out. The AdBlue side is topped up far less regularly, usually from a bottle, and usually by a person who has to stop and think where it goes. It is in that gap that the slip lives.
AdBlue in the diesel tank in Kings Hill: how it takes place
It is seldom carelessness. Three things tend to line up.
First, the warning. Low AdBlue brings a warning from your car, and running dry leads to limp mode — hence a rushed top-up, maybe before work off North Home Road, perhaps outside The Golden Farm on the way home that evening.
The old car's filler is where your hand reaches — but a rental car, a new car or a company car puts the fillers somewhere else. That's a second factor: a new motor.
Lastly, the spout goes in: diesel filler or AdBlue one, it goes in as easily, and after the tip begins, no part stops it. New Mills or the heart of Kings Hill: it takes the same few seconds either way.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all these take — so check them before you pour anything, on a drive in Cirencester or a forecourt around Kings Hill.
- Read the cap instead of going by position: AdBlue ones are frequently blue or marked "AdBlue", and diesel caps usually aren't.
- Check the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one.
- The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
- In your boot or under the bonnet: that's where your filler sits if it is not by your diesel cap, and the handbook tells you which.
- Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Kemble.
How to top up without AdBlue in the diesel tank
On the day the light appears — wherever it is across Gloucestershire — a routine to use.
- Pull in on level, motor off, with time to spare — never hurried on the side of Clifford Close.
- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Silly, perhaps, but it works.
- Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Gently is best, through the bottle's own spout, till it is full or the bottle runs out.
- Only after that, start your car: close the cap, check once more, and make sure your diesel cap was never opened.
Find at the second or third stage that AdBlue went in the diesel tank? That is where you stop. Skip stage five altogether.
AdBlue in your diesel tank already, in Kings Hill?
The short order of things, beginning with no starting your motor. Keep the ignition off too, because on many diesels switching it on alone starts your pump. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where your fuel is pulled from — so don't top up with diesel to dilute it.
The attendants at Tesco, Esso or any forecourt will usually help to push the vehicle away when you ask. Your own drive around Kings Hill is where it stays.
Already started? Stop when it's sensible, then turn off. On the M4, under 15 miles from Kings Hill, that means the next exit. Tell us about how far it went: a run towards Gloucester, under 25 miles away, is a bigger job than a short hop across Kings Hill.
When our technicians turn up around Kings Hill, what happens?
Anywhere your car has stopped, be it by Watermoor Church of England Primary School, beside Cirencester Town FC or at home, the van travels to it. We ask what went in, about how much, and whether it has run, since the answers settle this work and our price. You get that quote on the phone, before anyone heads out.
Then your tank is drained and your system purged thoroughly. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of it washes away by itself. That is why it counts more. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. We do not leave until it has been fired up and is running correctly.
If the engine hasn't run, most jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. The insurer usually wants an engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no deposit. It is worth checking your insurance while we travel to you: misfuelling cover comes with many policies.
