Marnhull: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
AdBlue already in the diesel tank? Then put this page down a moment, leave the ignition and engine off, then ring 0333 366 0103. In Marnhull, catching it before your motor turns usually leaves a drain and a full flush on the spot. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not.
AdBlue in a diesel motor: two tanks, two fillers
Plenty of newer diesels in Walton Elm, like those in Marnhull, run on two liquids; your engine gets only the diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
There's a filler on every tank. Plenty of vehicles have a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet. At the pump, your diesel side gets filled all the time. Much less commonly, the AdBlue side is topped up — mostly from a bottle, by someone working out where it goes. The mistake lives in that gap.
How AdBlue in your diesel tank happens in Marnhull
Seldom is it carelessness: usually three things coincide.
To start with, the warning. Low AdBlue brings a warning from your car, and letting it run dry leads to limp mode — hence a hurried top-up, perhaps before work off Church Hill, or at Crown Inn on the way home that evening.
Next, the hand goes for the cap it knew on the old motor — because a hire car, a new car or a company car places the fillers somewhere your last one did not.
Third, the spout fits: a diesel filler or AdBlue filler, it goes in as easily, and after the pour starts, no part halts it. Whether it occurs in Pillwell or the middle of Marnhull, it's the same few seconds.
How to tell the AdBlue filler from the diesel one
Whether a Marnhull forecourt or a drive out in Gannetts, take a few seconds over these before any is poured in.
- Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not where it sits.
- The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
- Check inside your fuel flap: plenty of motors have a label there saying which fuel goes where.
- Can't find it next to the diesel inlet? In that case look beneath the bonnet or inside the boot — the handbook says which.
- The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Gillingham (Dorset), ask before you leave, not when the light comes on.
AdBlue top-ups that never reach the diesel tank
For the day the light comes on — wherever you are around Dorset — a simple routine to use.
- Turn off after you park — flat ground, engine stopped, and not rushed by Burton Street at the roadside.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, perhaps, but it works.
- The diesel cap stays on. Where the two share a flap, make sure it's closed before the bottle comes up.
- Finish when that tank fills or the bottle is empty; before that, pour gently using the own spout.
- Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened.
Spot at stage two or three that it's already gone into the diesel side? So stop just there. Step five stays out.
Marnhull: already put AdBlue in the diesel tank?
Don't start your engine: that's where the short order of things begins. Leave your ignition off as well, since on plenty of diesels switching it on by itself starts the pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so don't top up with diesel to dilute it.
Ask the attendants to help roll the car clear of the pump if you are on a forecourt — the G&A Cook, the Murco or somewhere else. Leave it where it is if you are on your own driveway in Marnhull.
If the motor has already run, stop as soon as it is safe and switch off. The next exit is where to leave when you're on the M5, under 50 miles from Marnhull. Tell us roughly how far it went: a run towards Wells, under 25 miles away, is a bigger job than a short hop across Marnhull.
Marnhull: what occurs when our technicians arrive
Our engineers come to your car wherever it has stopped, whether that is outside St Gregory's Church of England Primary School, Marnhull, near Marnhull Village Hall or on your own driveway. Our engineers ask what went in, about how much, and if it has run, since those replies decide this work and our quote. Nobody heads out before you have had our quote over the phone.
The system is then purged thoroughly, after that tank is drained. Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of it clears out by itself. That is why it counts more. A test comes last: before that, fresh diesel is added, and the fuel filter is cleaned or changed as needed. We do not go until it has been fired up and is running properly.
With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which the motor has not run need about half an hour after we arrive. No money upfront; you settle up that day. At the end, a VAT invoice and a report from the engineer are handed to you for your insurer. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.

Marnhull and Dorset: AdBlue drains across the area
As a rural village, Marnhull has the same vans as surrounding places — Hains, Mounters — all the way across DT postcodes and the wider area beyond. A postcode starting DT10 1 gets the van to you fastest.
Your car stays put. Wherever it sits — beside St. Gregory's, on a layby heading to Marnhull Recreation Ground, on a drive — that is where it is cleared. Guessing won't help at the back of St Andrew, on a border, or somewhere hard to pin down; phone and ask.
In short, for Marnhull drivers
