Avoiding AdBlue in a Diesel Tank in Coffle End: Why It Occurs
AdBlue already in your diesel tank? In that case put this page down a moment, leave your ignition and motor off, and call 0333 366 0103. A drain plus a thorough flush, done just where the vehicle sits around Coffle End, is usually all it takes if caught before the engine runs. The rest of this page explains why it occurs and how to ensure it does not — handy if you're reading ahead of time.
AdBlue in a diesel car: two tanks, two fillers
Diesel feeds the engine — but many newer diesels driven around Coffle End and Radwell hold another liquid too. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.
Each tank has its own filler. Many of vehicles share a single flap for both, whereas others put the AdBlue filler to your boot or under the bonnet. Diesel goes in at every forecourt call-out, week in, week out. Rarely filled, AdBlue normally comes from a bottle, tipped by a driver who has to stop and think which cap to use. The mistake grows in that gap between the two.
How AdBlue in the diesel tank occurs around Coffle End
Three things tend to come together, and carelessness is rarely one of them.
On a drive off Station Road before work, or in the car park outside Fordham Arms on the way home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue runs low your car warns you, and once it's empty, limp mode follows.
New-to-you vehicles are next, too. Rentals, new motors and company motors place their fillers differently, and habit reaches for the cap it used on the old one.
Lastly, the bottle goes in: a diesel filler or AdBlue filler, it goes in just as readily, and once the pour starts, nothing halts it. Sharnbrook or the middle of Coffle End: it takes the same few seconds in both.
Telling the AdBlue filler from the diesel filler
A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Felmersham or a forecourt around Coffle End.
- Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
- Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one.
- The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where.
- In your boot or under the bonnet: that is where the filler is if it is not by your diesel cap, and the handbook says which.
- Check with 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 Bedford.
Topping up AdBlue without it reaching the diesel tank
Anywhere across Bedfordshire the light comes on, this is a routine for that day.
- Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Templars Way.
- Silly as it sounds, speaking "AdBlue" aloud while you unscrew the cap does the trick — after you have located the filler and read the cap.
- The diesel cap stays on. Where the two share a flap, make sure it's shut before lifting the bottle.
- Stop when the tank is topped up or the bottle is empty; before that, tip slowly through the own spout.
- Close the cap and check again. Make sure the diesel cap was never opened. Only then start the car.
Spot at step two or three that it's already gone into the diesel side? So stop right there. Never carry on to stage five.
AdBlue in the diesel tank already, in Coffle End?
Do not start the motor: that's where the short order of things begins. On many diesels the ignition alone runs the fuel pump, and so do not switch the car on. Diluting it with more diesel won't work, because AdBlue sinks to the bottom rather than blending — and that's where the fuel is drawn from.
At a forecourt — Shell, Pod Garage Supplies or any other — the staff will usually help push the car clear, when you ask. Your own drive in Coffle End is where it stays.
If the engine has already run, stop as soon as it is safe and switch off. The next exit is the place to leave when you're on the M1, under 15 miles from Coffle End. Tell us about how far it went: a run towards Milton Keynes, under 25 miles away, is a bigger job than a short hop across Coffle End.
Our arrival in Coffle End, and what occurs next
Our van comes to the vehicle wherever it stopped — your own drive, beside Sharnbrook Methodist Church, or by Sharnbrook Primary. Both the work and our price rest on three replies — which liquid, what quantity, and whether it's run — so we ask. You hear that quote on the phone, before anybody sets off.
Then your tank is drained and the system rinsed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush matters more here than with petrol. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before leaving, we start it and check that it is running properly.
If the motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. The insurer will ask for an engineer's report and the VAT invoice, and both are yours once the job is done. Payment is on the day, with no money upfront. Many insurance policies include misfuelling cover, so it is worth checking yours while we are on the way.
