Avoiding AdBlue in a Diesel Tank in Longford Turning: Why It Occurs

Caught before the motor runs, it is generally a drain and a thorough flush, done where your car is around Longford Turning.

AdBlue in a diesel car, and its separate tank

No single fluid but two: that's what plenty of newer diesels around Longford Turning and Greenfields run, with diesel for the motor. AdBlue goes to the 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. Many of vehicles share a single flap for both, whereas some move the AdBlue filler to 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 tops up the AdBlue side, from a bottle, and far less regularly. That gap is where the slip lives.

How does AdBlue in the diesel tank occur in Longford Turning?

Rarely is it carelessness: usually three things coincide.

First, the warning. Low AdBlue triggers a message from your car, and letting it run out leads to limp mode — so a hurried top-up, perhaps before work off Shrewsbury Road, perhaps at Kings Head Inn on the way home after work.

The old car's filler is where the hand goes — yet a rental car, a new vehicle or a company car puts the fillers somewhere else. That is a second factor: a new motor.

Third, the spout fits: a diesel filler or AdBlue filler, it slides in just as easily, and after the tip begins, no part halts it. Whether it takes place in Little Drayton or the middle of Longford Turning, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Longford Turning

Telling the AdBlue filler from the diesel filler

Check these first, on a forecourt in Longford Turning or a driveway over in Smythemoor. Seconds, no more.

  • Colour and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position.
  • On many cars, the size gives it away: AdBlue has the smaller filler neck.
  • Lift the filler flap and look for a label — many cars show what belongs in which inlet just there.
  • In the boot or under the bonnet: that's where your filler is if it is not by your diesel cap, and the handbook says which.
  • Picking up a hire or company car, say at the car park outside Prees? Ask the person who drove the vehicle last before you set off, rather than when the light comes on.

Topping up AdBlue without it reaching the diesel tank

When the light goes on, wherever across Shropshire, use this routine.

  • Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Wallace Way.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • The diesel cap remains on. Where the two sit under a flap, make sure it's shut before lifting the bottle.
  • Slowly does it, through the bottle's own spout, until it is full or the bottle is empty.
  • Close the cap and check again. Make sure your diesel cap was never opened. Only then start the car.

If at step two or three you find you have already poured into the diesel side, stop there. Leave out step five entirely.

Longford Turning: already put AdBlue in your diesel tank?

Then the order of things is short. Do not start the engine. On plenty of diesels the ignition alone runs the fuel pump, so don't switch the vehicle on. Diluting it with extra diesel fails, since AdBlue sinks to the bottom instead of blending — and that's where the fuel is sucked from.

Ask the attendants to help push the car clear of the petrol pump if you are at a forecourt — the Shell, the Morrisons or somewhere else. Your own driveway in Longford Turning is where it should stay.

When your engine has run already, stop somewhere safe then switch it off. On the M6, under 15 miles from Longford Turning, that means the next exit. Tell us roughly how far it went: a run towards Stoke-on-Trent, under 25 miles away, is a bigger job than a short hop across Longford Turning.

What happens when we turn up in Longford Turning

We come to the car wherever it has stopped, whether that is outside Market Drayton Junior School, close to Christ Church or on your own driveway. Our technicians ask what got in, about how much, and if it's run, because the replies determine the work and the quote. No one sets off until you have had our price by phone.

Your system is then cleaned thoroughly, after that tank is drained. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. Once the filter has been flushed — or renewed, if required — fresh diesel is added, and finally the car is tested. Before we leave, our technicians fire it up and confirm that it is running properly.

Most jobs are done in about half an hour after our engineers arrive, as long as your motor has not run — and the pumps our engineers use are fine on a live forecourt and quiet after dark beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is included in many insurance policies — so use the wait to look at yours.
