AdBlue in a Diesel Tank in Sydenham: How It Occurs and How to Prevent It
Pause reading for a moment when your diesel tank already holds AdBlue in it: ignition off, engine off, then call 0333 366 0103. Normally, when the motor has not run, it is drained and fully flushed where your car is around Sydenham. The remainder of this page covers why it takes place and how to ensure it does not — useful if you are reading before it has happened.
Why does AdBlue in a diesel motor need its own filler?
No single liquid but two: that is how plenty of newer diesels around Sydenham and Royal Leamington Spa carry, with diesel for your motor. Stored in a tank of its own, AdBlue is fed into your exhaust gas to clean it.
There's a filler on every tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the petrol pump, your diesel side gets filled constantly. Rarely topped up, AdBlue usually comes from a bottle, tipped by a driver who must stop and think what filler to use. The mistake grows in that gap between the two.
AdBlue in your diesel tank in Sydenham: how it takes place
Carelessness seldom causes it. What does is three things coming up together.
To start with, the warning. Low AdBlue brings a warning from your car, and letting it run out leads to limp mode — hence a hurried top-up, maybe before work off Chesterton Drive, perhaps outside The Grist Mill on the way home that evening.
New-to-you motors are next, as well. Rentals, new motors and company motors put their fillers differently, and the hand goes for the cap it used on the old one.
Nothing halts the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Sydenham or out in Whitnash.
Which filler is for AdBlue, and which for diesel?
Before you pour anything, whether on a drive in Campion Hills or a forecourt around Sydenham, check these. They take a few seconds.
- Where it sits can mislead; the cap doesn't. AdBlue caps are often blue or carry the name "AdBlue" — diesel caps usually do not.
- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.
- Look inside the fuel flap: many cars have a label there showing which fuel goes where.
- The handbook. If the filler isn't by your diesel cap, it's in the boot or under the bonnet, and 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 outside Leamington Spa, ask before you leave, not when the light comes on.
Topping up AdBlue without it reaching your diesel tank
On the day the warning appears — anywhere you are in Warwickshire — a routine to use.
- Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Prospect Road.
- Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap works — once you have found the filler and read the cap.
- The two behind a single flap? Then make sure the cap on the diesel side is still closed before lifting the bottle.
- Finish once that tank fills or the bottle is empty; until then, tip gently through the own spout.
- Before you start your car, close the cap and look again that your diesel cap never came off.
Stop there if you find, at stage two or three, that you've already poured into the diesel side. Don't go on to stage five.
AdBlue in your diesel tank already, around Sydenham?
What follows is a short order of things, starting with not starting the motor. Keep your ignition off too, since on many diesels switching it on alone runs the pump. Filling up with diesel will not dilute it: instead, AdBlue drops to the bottom of the tank, just where fuel is drawn from.
If you are on a forecourt, whether it's the Asda or the Morrisons, ask the staff to help push the car away from the pump. If you're on your own drive around Sydenham, leave the car where it stands.
When your motor has run by now, pull over safely and switch the vehicle off. Come off the M40 — under 3 miles out of Sydenham — at the first junction. A short hop across Sydenham is a smaller job than a run towards Coventry, under 10 miles away, so tell us about how far it went.
Sydenham: what occurs when our technicians get there
The van comes to your car wherever it stopped — your own drive, beside Syndenham Community Centre, or by Sydenham Primary School. We ask what got in, roughly how much, and if it's run, since those replies settle the work and our quote. On the phone call itself, you hear our price — before dispatch.
After that: draining, then a full flush of the whole system. Much more than with petrol, it counts with AdBlue: the crystals form, some metals corrode, and nothing clears away unaided, no matter how long it sits. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. The motor is started next and checked to confirm it runs properly, all before our technicians leave.
Most jobs are finished in roughly half an hour once our engineers arrive, provided the motor has not run — and the pumps our engineers use are fine on a busy forecourt and quiet at night beside a house. The insurer will ask for an engineer's report and the VAT invoice, and you get both at the end. Payment is on the day, with no money upfront. While we travel, have a look at your policy; many include cover for misfuelling.

AdBlue drains around Sydenham, and Warwickshire beyond
As a residential suburb, Sydenham shares its vans surrounding places — Radford Semele, Myton — all the way through CV postcodes and the wider area beyond. Fastest of all: quote a CV31 1 postcode to our van.
There's no need to shift the car. A driveway, a lay-by on the way to Redland Road Recreation Ground, a side street near St Margaret's Centre: our engineers drain the vehicle where it stands. Ring and ask instead of guessing if you are near a boundary, or somewhere hard to explain, like the back of Jubilee Leamington.
The short version for Sydenham people
Before you tip, read the cap. If AdBlue has gone in your diesel tank anyway, leave the car off and ring 0333 366 0103. Petrol in Diesel drains it where it waits, anywhere across Warwickshire.
