New Mill: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
Pause reading a minute if your diesel tank already has AdBlue in it: ignition off, engine off, and call 0333 366 0103. Caught before the motor runs, it is normally a drain and a thorough flush, done where the vehicle is in New Mill. The remainder of this page explains why it takes place and how to ensure it does not — useful if you're reading before it has happened.
Two fillers, two tanks: AdBlue in a diesel car
Diesel feeds your motor — but many current diesels driven around New Mill and Bulbourne hold a second liquid too. Stored in a tank of its own, AdBlue is sprayed into the exhaust gas to clean it.
Every tank comes with a filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Topping up your diesel side at the petrol pump happens constantly. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less frequently. Mistakes happen in the gap between them.
How AdBlue in your diesel tank happens around New Mill
Carelessness seldom causes it. Instead is three things coming up at once.
On a driveway off Chapel Meadow before work, or in the car park at The Grand Junction Arms on the way home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it is gone, limp mode kicks in.
New-to-you motors are second, as well. Hire cars, new motors and company vehicles place their fillers differently, and the hand reaches for the cap it used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. The same few seconds decide it, in the middle of New Mill or out in Tring Wharf.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all these take — so run through them before you pour anything, on a drive in Tring or a forecourt around New Mill.
- Check the cap rather than going by position: AdBlue ones are frequently blue or marked "AdBlue", and diesel caps usually aren't.
- Plenty of motors fit AdBlue the smaller neck of the two.
- The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where.
- The handbook. If your filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
- Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Tring.
Keeping AdBlue out of the diesel tank when you top up
Anywhere across Hertfordshire the light comes on, this is a routine for the day.
- Not in a rush on the side of Longbridge Close, not on a slope, not with your engine running: park then switch off properly.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, yes, yet it does the trick.
- The diesel cap remains on. When both sit under a flap, confirm it's shut before lifting the bottle.
- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
- Only then, start the vehicle: close the cap, check a second time, and make sure your diesel cap was never opened.
Stop there if you find, at stage two or three, that you have already poured into your diesel side. Do not go on to stage five.
Already put AdBlue in the diesel tank in New Mill?
Then the order of things is short. Do not start your engine. The fuel pump starts on plenty of diesels the moment the ignition goes on — and so leave it off. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is pulled from.
On a forecourt — Shell, Texaco or any other — the staff will normally help roll your car away, when you ask. Your own driveway in New Mill is the place it should stay.
If your engine has already run, stop as soon as it is safe then switch off. Come off the M1 — under 15 miles out of New Mill — at the next junction. Tell us roughly how far it went: a run towards St Albans, under 15 miles away, is a bigger job than a short hop across New Mill.
When we arrive around New Mill, what occurs?
Outside Dundale Primary School and Nursery, close to New Mill Baptist Church or on your own drive: wherever the vehicle has stopped, we come to it. We ask what was put in, about how much, and if it has run, since those answers decide this work and our price. No one sets off until you've heard the price by phone.
Next: a drain, then a full flush of the entire system. More than with petrol, it matters with AdBlue: crystals build up, certain metals are attacked, and nothing clears away unaided, however long it is left. A test is last: before that, clean diesel goes in, and your filter is flushed or changed as needed. The engine is fired up next and checked to make sure it runs correctly, all before our technicians leave.
With pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs in which your engine has not run take roughly half an hour after our engineers are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.

The car does not need to shift. Draining happens on the spot, whether a drive, a street by Tring Community Centre, or a layby on the way to Spider Park. Guessing won't help at the back of Tring Sports Centre, on a border, or somewhere awkward to describe; ring and ask.
