AdBlue in a Diesel Tank in Church End: How It Occurs and How to Stop It
Pause reading a minute when the diesel tank already has AdBlue in it: ignition off, engine off, then call 0333 366 0103. In Church End, finding it before your engine runs usually leaves a drain and a thorough flush where it stands. Nothing happened yet? Below, the rest of the page covers the reasons it takes place and the ways to avoid it for good.
Why does AdBlue in a diesel motor need its own filler?
Diesel goes to your motor — yet many newer diesels driven around Church End and Northall hold another liquid as well. The exhaust, not the engine, is where AdBlue ends up: dosed into the fumes to clean it, from its own tank.
Separate tanks, different fillers. Other cars put the AdBlue filler in your boot or under the bonnet; plenty of others place the two side by side behind one flap. Filling the diesel side at the pump happens constantly. Much less commonly, the AdBlue side gets topped up — mostly from a bottle, by someone working out where it goes. That gap is where the mistake lives.
How AdBlue in your diesel tank happens in Church End
Rarely is it carelessness: normally three things line up.
On a drive off Chiltern Avenue before work, or in the car park at The Swan heading home: that is where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low the car warns you, and if it's gone, limp mode kicks in.
The old car's filler is where the hand goes — but a rental car, a new motor or a company car keeps the fillers elsewhere. That is the second factor: an unfamiliar car.
Third, the bottle fits: a diesel filler or AdBlue one, it slides in just as readily, and after the pour starts, no part halts it. The same few seconds settle it, in the middle of Church End or out in Edlesborough.
How to tell the AdBlue filler from the diesel one
Before you pour anything, whether on a driveway in Ivinghoe Aston or a forecourt around Church End, check these. They take a few seconds.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by where it sits.
- Look at the size: the smaller filler neck is, on many motors, the AdBlue one.
- A label inside the fuel flap frequently says which fuel goes where, on plenty of vehicles. Check for it.
- The handbook shows which it is when the filler isn't next to your diesel cap: your boot, or under the bonnet.
- The previous driver will know. Ask when you pick up a rental or company car — from Cheddington's car park, say — rather than once the warning comes on.
How to top up without AdBlue in the diesel tank
On the day the warning appears — anywhere it is in Buckinghamshire — a simple routine to follow.
- Switch off once parked — flat ground, engine stopped, and never rushed by Church Croft on the verge.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
- The two under a single flap? So confirm the lid on your diesel side is still shut ahead of lifting the bottle.
- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
- Before starting the car, close the cap and look a second time that your diesel cap never came off.
If at step two or three you find you have already poured into the diesel side, stop there. Skip stage five altogether.
Already put AdBlue in your diesel tank in Church End?
Don't start your engine: that's how the short order of things begins. Keep the ignition off as well, because on plenty of diesels switching it on alone starts your pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is pulled from — so do not top up with diesel to dilute it.
The attendants at BP, Esso or another forecourt will usually help to push your car away if you ask. Leave it where it is if you are on your own drive in Church End.
Already started? Stop once it's safe, then turn off. Church End lies under 10 miles from the M1; there, use the next exit. Roughly how far did it go? Crossing Church End is less a job than a run of under 15 miles towards St Albans, and so say.
What happens when we arrive around Church End
Our van comes to your car wherever it has come to rest — your own driveway, near Saint Mary's, or outside Edlesborough Primary Academy. What fluid went in, the quantity, and whether it ran: our technicians ask since the answers decide the work and quote. The quote comes on the call, ahead of any van leaving.
After that: a drain, then a full flush of the entire system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Filter flushed or, if needed, replaced; clean diesel in; and then a check of your vehicle. We do not go until it has been started and is running properly.
Most jobs are finished in roughly half an hour after we get there, as long as the motor has not run — and the pumps our technicians use are safe on a busy forecourt yet quiet after dark outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth looking at your insurance while we travel to you: misfuelling cover comes with many policies.
