AdBlue in a Diesel Tank in Chadwell St Mary: Why It Happens and How to Prevent 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. Usually, if the engine hasn't turned, it's emptied and fully flushed where the car sits in Chadwell St Mary. The rest of this page explains why it occurs and how to make sure it doesn't — useful if you're reading ahead of time.
AdBlue in a diesel vehicle: two tanks, two fillers
Many modern diesels on the roads about Chadwell St Mary and Little Thurrock carry two liquids, not one. Diesel goes to your engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
Separate tanks, different fillers. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling your diesel side at the petrol pump happens constantly. Far less commonly, the AdBlue side gets topped up — mostly from a bottle, by a person thinking about where it goes. It is in the gap that the mistake happens.
Chadwell St Mary: how AdBlue in the diesel tank takes place
Three things tend to line up, and carelessness is seldom one of them.
First, the warning. Low AdBlue brings a warning from your car, and running dry means limp mode — so a hurried top-up, perhaps before work off River View, or outside Chadwell Arms on the way home that evening.
The old car's cap is where your hand goes — yet a rental car, a new vehicle or a company car keeps the fillers elsewhere. That's the second factor: a new car.
No part stops the tip after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Biggin or the middle of Chadwell St Mary: it is the same few seconds either way.
How to tell the AdBlue filler from the diesel one
Be it a Chadwell St Mary forecourt or a drive over in Thurrock Park, spend a few seconds over these before any is poured in.
- Position misleads; the cap doesn't. AdBlue ones are often blue or carry the word "AdBlue" — diesel ones usually don't.
- On many motors, the size tells: AdBlue gets the smaller filler neck.
- Open the flap and look for a label — many motors mark which belongs in which inlet right there.
- In your boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook says which.
- The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Tilbury Town, ask before you leave, not when the light comes on.
Topping up AdBlue without it reaching the diesel tank
For the day the light comes on — anywhere you are in Essex — a simple routine to use.
- Not in a rush on the side of Linford Road, not on a slope, not with the engine running: park then switch off first.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Close the cap and check again. Make sure your diesel cap was never opened. Only then start the car.
If at step two or three you find you have already poured into the diesel side, stop there. Stage five stays off limits.
Chadwell St Mary: already put AdBlue in your diesel tank?
Do not start your engine: that is where the short order of things begins. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from.
The attendants at Esso, Asda or any forecourt will usually lend a hand pushing the vehicle clear when you ask. On your own drive in Chadwell St Mary? Then your car remains put.
If your engine has already run, stop as soon as it is safe and switch off. Chadwell St Mary sits under 5 miles from the M25; on it, take the first exit. Tell us about how far it went: a run towards Southend-on-Sea, under 25 miles away, is a bigger job than a short hop across Chadwell St Mary.
What occurs when we get there around Chadwell St Mary
Anywhere your car has stopped, be it outside Chadwell St Mary Primary School, beside St Mary's Church or at home, the van travels to it. Both the work and the quote depend on three answers — which liquid, what amount, and whether it's run — so our engineers ask. You get that quote by phone, before anybody heads out.
Then that tank is cleared and the system cleaned thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Once the fuel filter is cleaned — or replaced, where needed — fresh diesel goes in, and then your car gets tested. We do not leave until it has been started and is running properly.
Most jobs are finished in roughly half an hour once we get there, provided your motor has not run — and the pumps our engineers use are fine on a busy forecourt yet quiet at night outside a house. Paying is on the day, not upfront, and you receive the paperwork your insurer wants: an engineer report and a VAT invoice. Before we get there, take a look at your insurance documents; plenty carry cover for misfuelling.
