Holmesdale: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
AdBlue already in the diesel tank? Then set this page down a moment, leave the ignition and motor off, then ring 0333 366 0103. In Holmesdale, finding it before the motor turns usually leaves a drain and a full flush where it stands. The rest of this page covers why it occurs and how to ensure it does not — useful if you're reading before it has happened.
Why does AdBlue in a diesel motor need its own filler?
Plenty of modern diesels in Holmley Common, like those in Holmesdale, run on two fluids; your motor gets only the diesel. Its own tank keeps it, and from there it is sent to your exhaust, and there a spray cleans the fumes.
Each tank has its own filler. Plenty of motors have a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. Diesel goes in at each forecourt call-out, again and again. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less frequently. That gap is where the mistake lives.
Holmesdale: how AdBlue in your diesel tank occurs
Seldom is it carelessness: normally three things coincide.
The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Oakdell before work, or in the car park at The Royal Oak on the way home.
Unfamiliar vehicles come next, as well. Rentals, new motors and company motors place their fillers differently, and the hand goes for the cap used on the old one.
Lastly, the bottle fits: diesel filler or AdBlue one, it slides in just as easily, and after the pour begins, no part stops it. Summerley or the middle of Holmesdale: it takes the same few seconds either way.
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 driveway in Batemoor or a forecourt in Holmesdale.
- Check the cap rather than going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel ones usually aren't.
- The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two.
- The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where.
- The handbook says where it lives when the filler is not next to your diesel cap: the boot, or under the bonnet.
- Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Dronfield.
Topping up AdBlue without it reaching your diesel tank
Anywhere across Derbyshire the light comes on, this is a routine for that day.
- Not in a rush on the side of Stonelow Road, not on a slope, not with your engine running: park and switch off properly.
- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Silly, perhaps, yet it works.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on.
- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
- Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the vehicle.
If at step two or three you find you have already poured into the diesel side, stop there. Never go on to stage five.
Already put AdBlue in your diesel tank around Holmesdale?
What follows is a short order of things, starting with not starting your engine. Keep the ignition off as well, because on plenty of diesels it by itself starts your pump. Diluting it with more diesel fails, since AdBlue sinks to the base instead of blending — and that is where your fuel is pulled from.
The staff at Total, Sainsbury's or another forecourt will normally lend a hand to push your car away when asked. At home around Holmesdale? So your car remains where it is.
When the motor has been run by now, stop safely and turn the vehicle off. The next exit is the place to leave when you are on the M1, under 10 miles from Holmesdale. About how far did it go? Crossing Holmesdale is less work than a run of under 10 miles towards Sheffield, so say.
When we arrive around Holmesdale, what occurs?
Outside Northfield Junior School, close to St Philip or on your own driveway: wherever your car has stopped, we come to it. Which fluid was put in, the amount, and whether it ran: our technicians ask because those answers set the work and quote. That quote comes over the phone, before any van leaves.
After that: a drain, then a thorough flush of the whole system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush matters more with AdBlue than with petrol. Testing comes last: before that, fresh diesel is added, and your filter is flushed or replaced if necessary. After that our technicians start it and check it runs properly before we go.
If your motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your insurance as the van travels to you: misfuelling cover comes with plenty of policies.
