Festubert Place: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

Pause reading for a moment if the diesel tank already has AdBlue in it: ignition off, motor off, then phone 0333 366 0103. Caught before the motor runs, it is generally a drain and a thorough flush, done where your car is in Festubert Place. Not happened yet? Further down, the rest of the page covers the why it happens and the how to avoid it altogether.

AdBlue in a diesel vehicle: two tanks, two fillers

Diesel feeds your motor — but many newer diesels seen round Festubert Place and Bromley hold a second fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Every tank has one filler of its own. Some cars put the AdBlue filler in your boot or under the bonnet; plenty of others place the two side by side under one flap. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is filled far less commonly, normally from a bottle, and usually by someone who has to stop and think where it goes. That gap is where the mistake lives.

AdBlue in your diesel tank in Festubert Place: how it takes place

Seldom is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the car drops into limp mode. So the top-up is done in a hurry: on a driveway off Stafford Road before work, or in the car park outside The Morgan Arms on the way home.

New-to-you cars come second, too. Hire cars, new vehicles and company vehicles place their fillers differently, and habit reaches for the cap used on the old one.

No part halts the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's seconds, be it out in Bow or bang in the centre of Festubert Place.

The AdBlue filler and your diesel filler: telling them apart

A few seconds is all these take — so run through them before you tip anything, on a driveway in Mile End or a forecourt in Festubert Place.

  • Position misleads; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel ones normally do not.
  • Many cars fit AdBlue the smaller neck of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where.
  • Can't see it next to your diesel inlet? In that case look below the bonnet or inside your boot — the owner's manual will say where.
  • Picking up a hire or company car, perhaps at the car park at Hackney Wick? Check with the person who drove the car last before you set off, rather than when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

The day the light comes on, anywhere around Greater London, use this routine.

  • Turn off once parked — level ground, motor off, and not rushed by Balmer Road on the verge.
  • Locate the AdBlue filler, check the cap, and say the name "AdBlue" out loud while you unscrew it. It sounds daft. It does the trick.
  • The diesel cap remains on. Where both share a flap, confirm it's closed before lifting the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Shut the cap, and check once more — making sure your diesel filler stayed closed the whole time. After that, start the vehicle.

Spot at step two or three that it has already gone into your diesel side? Then stop just there. Don't carry on to step five.

Festubert Place: already put AdBlue in your diesel tank?

Do not start your engine: that's where the short order of things starts. On plenty of diesels the ignition alone runs the fuel pump, so do not switch the car on. Filling up with diesel will not dilute it: rather than mixing, AdBlue drops to the base of that tank, just where fuel is taken from.

On a forecourt — Texaco, Shell or another — the staff will normally help push the vehicle away, when you ask. On your own drive in Festubert Place? So the car stays where it is.

Where your engine has been run by now, stop somewhere safe then switch the car off. Leave the M11 — under 5 miles out of Festubert Place — at the next junction. A short hop across Festubert Place is a smaller job than a run towards London, under 3 miles away, so tell us about how far it went.

What happens when our engineers turn up around Festubert Place

The van reaches your car anywhere it stopped — your own drive, near Gurdwara Sikh Sangat, or outside Malmesbury Primary School. Both the work and the price depend on three replies — which liquid, what amount, and if it has run — so our engineers ask. You hear that price by phone, before anyone sets off.

Then that tank is emptied and the fuel system rinsed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that matters more here than with petrol. Filter flushed or, where needed, replaced; clean diesel in; and then a check of your car. We don't leave until it has been fired up and is running correctly.

Unrun vehicles usually need a half-hour visit from arrival. The kit is safe on a busy forecourt, and hushed enough for a driveway after dark. Paying happens on the day, not upfront, and you are given the paperwork your insurer wants: an engineer's report and a VAT invoice. Before we get there, have a look at your insurance documents; plenty include cover for misfuelling.

AdBlue drains in Festubert Place and across Greater London

Festubert Place is a neighbourhood, and the teams that cover it also work the places around it, Hitchin Square and Old Ford among them, across the E postcode area. Fastest of all: give a E3 2 postcode to the van.

Moving the vehicle is not needed. Anywhere it stands — beside Charles Coborn, on a layby en route to Selwyn Green, at home — that is where it is emptied. Awkward to pin down, like the back of Antill Road Centre? Close to a border? Checking is better than guessing, and so phone.
