Preventing AdBlue in a Diesel Tank in Coxs Green: Why It Happens
If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and the ignition off and call 0333 366 0103. In Coxs Green, finding it before the engine runs normally means draining and a full flush where it stands. If you're reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't.
Why does AdBlue in a diesel vehicle need its own filler?
Diesel feeds your motor — but many modern diesels seen around Coxs Green and Blackmoor hold a second fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Every tank has one 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 the boot or under the bonnet. Topping up the diesel side at the pump happens all the time. Someone who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less regularly. The slip lives in that gap.
Coxs Green: how AdBlue in the diesel tank occurs
Three things tend to line up, and carelessness is rarely one of them.
On a drive off Cox's Green before work, or in the car park outside The Golden Lion heading home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and once it's empty, limp mode follows.
The old car's cap is where your hand reaches — yet a rental car, a new car or a company car keeps the fillers elsewhere. That is a second thing: an unfamiliar vehicle.
Lastly, the spout goes in: diesel filler or AdBlue filler, it slides in as easily, and once the pour starts, no part stops it. Butts Batch or the middle of Coxs Green: it is the same few seconds either way.
The AdBlue filler and your diesel filler: telling them apart
Look at these first, on a forecourt in Coxs Green or a drive out in Havyatt Green. Seconds, that's all.
- Where it sits misleads; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel caps normally do not.
- On plenty of motors, the size gives it away: AdBlue gets the smaller filler neck.
- Check inside your fuel flap: many motors carry a label there saying which fuel goes where.
- In your boot or under the bonnet: that's where your filler is if it's not by the diesel cap, and the handbook says which.
- The person who drove it last. On a hire or company car collected from somewhere like the car park outside Yatton, ask before you leave, not when the light comes on.
Topping up AdBlue without it reaching your diesel tank
The day the light comes on, wherever across Somerset, follow this routine.
- Turn off after you park — level ground, motor off, and never rushed by Whiting Way on the verge.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, perhaps, but it does the trick.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Shut the cap, and look once more — confirm the diesel cap stayed closed throughout. Only then, start the car.
If at step two or three you find you have already poured into the diesel side, stop there. Never go on to stage five.
Put AdBlue in your diesel tank around Coxs Green already?
Short list, then. Top of that: the engine remains unstarted. The fuel pump starts on plenty of diesels the moment the ignition goes on — so leave it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where the fuel is sucked from.
The attendants at Esso, Murco or any forecourt will normally lend a hand to push the car clear if asked. On your own drive in Coxs Green? Then the car remains put.
Where your engine has been run by now, stop somewhere safe and switch the car off. Leave the M5 — under 5 miles out of Coxs Green — at the first junction. Roughly how far did it go? Hopping across Coxs Green is less work than a run of under 10 miles to Bristol, and so say.
What happens when our engineers arrive in Coxs Green
Anywhere your car has stopped, be it by Wrington Church of England Primary School, near Memorial Hall or on your own drive, our van comes to it. Those replies settle the work and the quote, and so our engineers ask what got in, roughly how much, and whether it's run. That quote comes over the phone, ahead of any van leaving.
After that: draining, then a thorough flush of the entire system. Unlike petrol, AdBlue forms crystals and attacks some fuel-system metals, and none of it washes away by itself. That is why it counts more. After your filter has been flushed — or replaced, if required — fresh diesel goes in, and finally the vehicle gets tested. Next we fire it up and make sure it runs properly before we go.
Most jobs are done in roughly half an hour after our engineers arrive, provided your motor has not run — and the pumps our engineers use are fine on a live forecourt yet quiet after dark beside a house. The insurer usually wants the engineer's report and the VAT invoice, and you get both once this job is done. Payment comes on the day, with no deposit. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we're on the way.
