How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Dennis Green
If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and your ignition off then phone 0333 366 0103. Caught before your motor runs, it is generally a drain and a thorough flush, done where your car is in Dennis Green. Here in advance? Then the rest explains why it comes about and how to prevent it ever happening.
Two fillers, two tanks: AdBlue in a diesel vehicle
Not one liquid but two: that is what plenty of modern diesels near Dennis Green and Gamlingay Cinques run, with diesel feeding your motor. Its own tank keeps it, and from there it is sent to the exhaust, and there a spray treats the gas.
Each tank has its own filler. Some cars keep the AdBlue filler in your boot or under the bonnet; plenty of others have both together behind one flap. The diesel side is filled at the petrol pump all the time. Rarely topped up, AdBlue usually goes in out of a bottle, tipped by a driver who has to stop and think which cap to use. It's in that gap that the slip lives.
AdBlue in the diesel tank around Dennis Green: how it occurs
It's seldom carelessness. Three things tend to line up.
The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Heath Road before work, or in the car park at The Cock Inn on the way home.
Then your car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have 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, and so nothing stops the tip once it has started. The same few seconds decide it, in the middle of Dennis Green or out in Little Heath.
Which filler is for AdBlue, and which for diesel?
A few seconds is all these take — so check them before you tip anything, on a driveway in Dutter End or a forecourt in Dennis Green.
- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by position.
- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.
- Lift the filler flap and look for a label — plenty of vehicles show what goes in which filler right there.
- The handbook shows where it is when the filler is not next to your diesel cap: the boot, or under the bonnet.
- The previous driver knows. Check when you pick up a rental or fleet car — at Sandy's car park, perhaps — rather than once the warning appears.
Keeping AdBlue out of your diesel tank when you top up
Anywhere in Cambridgeshire the light comes on, here is a routine for the day.
- Turn off after you park — level ground, engine stopped, and not rushed by Park Lane at the roadside.
- Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap works — once you have located your filler and read the cap.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on.
- Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
- Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle.
Find at stage two or three that it has already gone into your diesel side? So stop just there. Stage five stays off limits.
AdBlue in the diesel tank already, around Dennis Green?
Brief list, then. Top of that: your engine remains unstarted. On many diesels the ignition alone runs the fuel pump, so don't switch the car on. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from.
If you are at a forecourt, whether it is the Gulf or the BP, ask the staff to help push your car clear of the petrol pump. Leave it where it is if you are on your own drive in Dennis Green.
If your motor has already run, stop as soon as it is safe and switch off. The next junction means where to come off if you're on the A1(M), under 10 miles from Dennis Green. A short hop across Dennis Green is a smaller job than a run towards Cambridge, under 15 miles away, so tell us roughly how far it went.
Dennis Green: what takes place when we arrive
Wherever the car came to rest, whether outside Gamlingay Village Primary, beside Gamlingay Social Club or at home, the van comes to it. Those replies decide the work and the quote, and so we ask what went in, about how much, and if it has run. The quote is given on the call, before any van leaves.
Next: draining, then a full flush of the whole system. Much more than with petrol, it counts with AdBlue: the crystals build up, certain metals are attacked, and nothing washes away on its own, however long it sits. After the fuel filter has been flushed — or renewed, if needed — fresh diesel is added, and then your car gets tested. Then our engineers fire it up and check it runs smoothly before we leave.
Unstarted cars usually mean a half-hour job from arrival. The kit is fine on a live filling station, and hushed enough for a driveway after dark. Paying is on the day, not upfront, and you receive the documents your insurer asks for: an engineer report and a VAT invoice. It is worth looking at your insurance as the van travels to you: misfuelling cover is included with plenty of policies.
