AdBlue in a Diesel Tank in Bellinge: Why It Occurs and How to Prevent It

Pause reading a minute when your diesel tank already has AdBlue in it: ignition off, engine off, and phone 0333 366 0103. Caught before your motor runs, it's normally a drain and a thorough flush, done where the car is in Bellinge. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not.

AdBlue in a diesel motor: two tanks, two fillers

Many modern diesels on the roads around Bellinge and Ecton Brook carry two liquids, not one. Diesel goes to the engine. Its own tank holds it, and from there it goes to the exhaust, where a spray treats the gas.

Each tank has its own filler. Under one flap, next to each other: that is the arrangement on a lot of cars. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. At the pump, the diesel side is topped up all the time. Rarely topped up, AdBlue normally goes in out of a bottle, poured by a driver who must stop and think what cap to use. The error lives in that gap.

How does AdBlue in your diesel tank take place around Bellinge?

Seldom is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Faracre Court before work, or in the car park outside Deers Leap on the way home.

Unfamiliar vehicles come second, as well. Rentals, new vehicles and company vehicles put their fillers in new places, and habit 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 once it has started. The same few seconds decide it, in the middle of Bellinge or out in Little Billing.

Flushing a diesel fuel system after AdBlue, Bellinge

Telling the AdBlue filler from the diesel filler

Check these first, on a forecourt around Bellinge or a drive out in Blackthorn. Seconds, that's all.

  • Position misleads; the cap does not. AdBlue ones are often blue or bear the word "AdBlue" — diesel caps normally don't.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where.
  • The handbook. If your filler is not by your diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • Picking up a hire or company car, perhaps at the car park outside Northampton? Check with whoever drove the vehicle last before you set off, rather than when the light comes on.

AdBlue top-ups that never reach your diesel tank

A routine for the day the light comes on, wherever in Northamptonshire that is.

  • Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Glade Close.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • Both behind one flap? So confirm the cap on the diesel filler stays shut before lifting the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
  • Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car.

Discover during the second or third stage that the bottle went in the diesel filler? That is where you stop. Never go on to stage five.

AdBlue in the diesel tank already, around Bellinge?

Don't start your engine: that is how the short order of things starts. On plenty of diesels your ignition alone runs the fuel pump, so don't switch the vehicle on. Topping up with diesel will not thin it: instead, AdBlue drops to the bottom of your tank, just where fuel is taken from.

The attendants at BP, Tesco or any forecourt will usually lend a hand pushing the car away when asked. Leave it where it is if you're on your own driveway around Bellinge.

When the engine has been run by now, stop somewhere safe and turn the car off. The next exit is where to leave when you are on the M1, under 10 miles from Bellinge. Mileage matters — a short hop across Bellinge makes a smaller job than driving under 15 miles towards Milton Keynes — so say about how far it went.

Bellinge: what occurs when our technicians turn up

Outside St Andrew's Ceva Primary School, close to Bellinge Community Centre or on your own drive: wherever the car has stopped, our engineers come to it. What fluid went in, the amount, and whether it ran: our technicians ask because those replies decide the work and quote. On the phone call itself, you are told the price — ahead of anything else.

Emptying that tank comes next, then a thorough flush of your system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Testing is at the end: before that, fresh diesel goes in, and the filter is cleaned or replaced if necessary. We don't leave until it has been started and is running properly.

Most jobs are done in about half an hour after our technicians arrive, provided the motor has not run — and the pumps we use are fine on a busy forecourt and quiet at night outside a house. Payment happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer report and a VAT invoice. Misfuelling cover is part of many insurance policies — so use the wait to look at yours.
