Preventing AdBlue in a Diesel Tank in Spitalbrook: Why It Occurs
Keep the motor and ignition off then ring 0333 366 0103 now — reading can wait if AdBlue is already in your diesel tank. Around Spitalbrook, catching it before the engine runs normally leaves draining and a full flush on the spot. Here before the event? In that case the rest explains why it happens and how to prevent it ever happening.
Two fillers, two tanks: AdBlue in a diesel vehicle
Many current diesels on the roads around Spitalbrook and Keysers Estate carry two liquids, not one. Diesel goes to your engine. The exhaust, not your motor, is where AdBlue goes: sprayed into the gas to fresh them, from a separate tank.
Separate tanks, different fillers. Other motors put the AdBlue filler in your boot or under the bonnet; a lot of others have the two together under one flap. The diesel side is filled at the pump all the time. The AdBlue side is topped up far less often, normally from a bottle, and normally by someone who has to stop and think where it goes. That gap is where the slip lives.
Spitalbrook: how AdBlue in your diesel tank happens
Carelessness seldom causes it. What does is three things lining up at once.
Haste follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off St David's Drive, or on the way home in the car park at The George III.
Unfamiliar cars come second, as well. Hire cars, new vehicles and company cars put their fillers differently, and the hand goes for the cap used on the old one.
A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the tip, after begun, keeps on. Hoddesdon or the middle of Spitalbrook: it is the same few seconds in both.
Which filler is for AdBlue, and which for diesel?
Check these first, on a forecourt around Spitalbrook or a driveway out in Dobbs Weir. Seconds, no more.
- Check the cap rather than going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally are not.
- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.
- A label inside your fuel flap often says which fuel goes where, on many cars. Check for it.
- Cannot find it next to the diesel filler? In that case look beneath the bonnet or in your boot — the owner's manual will say which.
- Picking up a hire or company car, perhaps at the car park at Broxbourne? Check with whoever drove it last before you set off, rather than once the light goes on.
How to top up without AdBlue in your diesel tank
A routine for the day the light comes on, wherever in Hertfordshire that is.
- Park then switch off. Not on a slope, not with your motor running, and not in a rush on the side of High Road Broxbourne.
- Locate the AdBlue filler, read the cap, and speak the word "AdBlue" aloud while you unscrew it. It sounds silly. It does the trick.
- The diesel cap stays on. When the two sit under a flap, confirm it is closed before the bottle comes up.
- Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Before starting the car, shut the cap and look a second time that your diesel cap never opened off.
If at stage two or three you find you have already poured into the diesel side, stop there. Never carry on to step five.
AdBlue in the diesel tank already, around Spitalbrook?
Then the order of things is short. Don't start the engine. Leave your ignition off as well, since on plenty of diesels it by itself runs your pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is pulled from.
The attendants at Shell, Sainsbury's or another forecourt will usually help to push your car clear when you ask. Your own driveway in Spitalbrook is where it stays.
Stop as soon as it is safe then switch off, if your engine has already run. Spitalbrook sits under 5 miles from the M25; on it, take the first junction. A short hop across Spitalbrook is a smaller job than a run towards St Albans, under 15 miles away, and so tell us about how far it went.
Spitalbrook: what takes place when our technicians get there
Wherever the vehicle has stopped, be it by St Cross Catholic Primary School, beside Lowewood Museum or at home, the van comes to it. Our engineers ask what got in, roughly how much, and whether it has run, because the answers decide the work and the price. The price is given over the phone, ahead of any van leaving.
Emptying the tank comes next, followed by a full flush of your system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. Filter cleaned or, where needed, replaced; clean diesel in; then a test of your vehicle. Next our technicians fire it up and check it runs smoothly before we go.
Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the motor hasn't run take about half an hour after we arrive. Paying happens on the day, not upfront, and you are given the documents your insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of many insurance policies — so make use of the wait to look at yours.

Spitalbrook and Hertfordshire: AdBlue drains across the area
As a residential suburb, Spitalbrook has the same vans as surrounding places — Broxbourne, High Leigh — right across EN postcodes and the wider area beyond. A postcode starting EN11 8 gets our van to you fastest.
Moving the car isn't needed. Wherever it sits — near Spotlight Theatre, on a lay-by heading to Cock Lane Open Space, on a drive — that is where it is cleared. Tricky to pin down, like the back of Bollescroft? By a border? Asking beats assuming, so ring.
In short, for Spitalbrook people
Before you tip, read the cap. Petrol in Diesel empties it where it stands, anywhere in Hertfordshire, if AdBlue has gone in your diesel tank regardless — so leave it off and phone 0333 366 0103.
