How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Holloway Hill
Leave your motor and ignition off and phone 0333 366 0103 first — the rest can wait when AdBlue is already in the diesel tank. Caught before the motor runs, it is generally a drain and a thorough flush, done where the car is around Holloway Hill. Here before the event? Then what follows explains why it comes about and what to prevent it ever happening.
AdBlue in a diesel motor, and its separate tank
Plenty of newer diesels on the roads about Holloway Hill and Ockford Ridge carry two liquids, not one. Diesel goes to your engine. AdBlue's own tank keeps it, and from there it is sent to the exhaust, and there a spray treats the fumes.
Every tank comes with one filler of its own. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. Someone who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and far less regularly. That gap is where the slip lives.
Holloway Hill: how AdBlue in your diesel tank occurs
Carelessness rarely explains it. Instead is three things lining up together.
The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Duncombe Road before work, or in the car park at Inn on the Lake on the way home.
The old car's filler is where your hand reaches — but a rental car, a new motor or a company car keeps the fillers somewhere else. That's the second thing: an unfamiliar car.
Lastly, the bottle fits: diesel filler or AdBlue filler, it goes in just as easily, and after the tip begins, nothing stops it. The same few seconds decide it, in the middle of Holloway Hill or out in Crownpits.
Telling the AdBlue filler from the diesel filler
Be it a Holloway Hill forecourt or a driveway over in Aarons Hill, take a few seconds over these before any is poured in.
- The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap normally isn't. Read it rather than going by position.
- Look at the size: the smaller neck is, on plenty of motors, the AdBlue one.
- Look inside your fuel flap: many cars carry a label there saying which fuel goes where.
- The handbook says which it lives if your filler isn't next to the diesel cap: your boot, or under the bonnet.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Godalming, ask before you leave, not when the light comes on.
Topping up AdBlue without it reaching your diesel tank
Wherever in Surrey the light comes on, here is a routine for the day.
- Not in a rush on the side of Shackstead Lane, not on a slope, not with the engine running: park and switch off properly.
- Silly as it sounds, saying "AdBlue" out loud as you unscrew the cap works — after you've found the filler and read it.
- The diesel cap stays on. Where both sit under a flap, confirm it is closed before lifting the bottle.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Before starting the car, shut the cap and check a second time that your diesel cap never came off.
If at stage two or three you find you have already poured into the diesel side, stop there. Never go on to step five.
Holloway Hill: already put AdBlue in the diesel tank?
Short order, then. First: the engine stays unstarted. On many diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so do not top up with diesel to thin it.
If you're at a forecourt, whether it is the JET or the Sainsbury's, ask the attendants to help push your car away from the petrol pump. Your own drive in Holloway Hill is the place it stays.
Already started? Pull over once it's safe, then switch off. Holloway Hill sits under 15 miles from the M3; there, take the first exit. Mileage matters — a quick hop across Holloway Hill is a smaller job than driving under 25 miles towards Chichester — so say roughly how far it went.
Our arrival around Holloway Hill, and what takes place next
Outside St Edmund's Catholic Primary School, close to St Edmunds or on your own driveway: wherever the car has stopped, we come to it. Both the work and our quote rest on three answers — which liquid, what amount, and if it has run — so we ask. During the call itself, you are told the quote — ahead of dispatch.
Emptying the tank comes next, then a thorough flush of the fuel system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither clears out by itself. Hence it matters more. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. We do not leave until it has been fired up and is running smoothly.
Most jobs are done in roughly half an hour once we arrive, provided the engine has not run — and the pumps our technicians use are fine on a live forecourt and quiet after dark beside a house. Paying happens on the day, not upfront, and you receive the documents an insurer asks for: an engineer report and a VAT invoice. Misfuelling cover is part of plenty of insurance policies — and so make use of the wait to look at yours.
