AdBlue in a Diesel Tank in Warings Green: How It Occurs and How to Prevent It

Leave your engine and ignition off and phone 0333 366 0103 first — the rest can wait when AdBlue is already in the diesel tank. A drain plus a full flush, done just where your vehicle stands in Warings Green, is normally all it needs when caught before your engine runs. Reading in advance? In that case what follows covers how it comes about and what to prevent it happening at all.

AdBlue in a diesel car, and its separate tank

Plenty of newer diesels on the roads about Warings Green and Cheswick Green carry two liquids, not one. Diesel goes to your motor. Your exhaust, not the motor, is where AdBlue ends up: dosed into the gas to clean it, from a separate tank.

Every tank comes with a filler of its own. Plenty of cars share a single flap for both, while some move the AdBlue filler to the boot or under the bonnet. The diesel side is fuelled at the pump all the time. Far less frequently, the AdBlue side gets filled — normally from a bottle, by someone working out where it goes. The mistake grows in that gap between them.

Warings Green: how AdBlue in your diesel tank occurs

Three things tend to line up, and carelessness is seldom one of them.

On a drive off Warings Green Road before work, or in the car park at Blue Bell Cider House heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low your car warns you, and once it's empty, limp mode follows.

Then, your hand reaches for the cap it knew on the old motor — since a rental car, a new car or a company car places the fillers where your last one did not.

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 after it has started. Salter Street or the middle of Warings Green: it takes the same few seconds either way.

Flushing a diesel fuel system after AdBlue, Warings Green

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 drive in Box Trees or a forecourt in Warings Green.

  • The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by position.
  • On plenty of motors, size tells: AdBlue gets the smaller filler neck.
  • A label inside your fuel flap often shows which fuel goes where, on many vehicles. Check for it.
  • Can't find it beside your diesel inlet? Then look beneath the bonnet or in the boot — the owner's manual will say which.
  • Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at The Lakes.

AdBlue top-ups that never reach your diesel tank

Wherever in West Midlands the light comes on, here is a routine for that day.

  • Not in a rush on the side of Illshaw Heath Road, not on a slope, not with your engine running: park and switch off first.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
  • Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Finish when that tank fills or the bottle runs dry; until then, pour gently through its own spout.
  • Close the cap, and look once more — confirm the diesel filler stayed shut throughout. After that, start the vehicle.

Find at stage two or three that it has already gone into your diesel side? Then stop right there. Stage five is off limits.

Already put AdBlue in your diesel tank around Warings Green?

Do not start the motor: that's where the short order of things starts. Leave your ignition off too, because on plenty of diesels it alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where your fuel is sucked from — so do not top up with diesel to dilute it.

The staff at Murco, Shell or any forecourt will normally help pushing the vehicle away if asked. If you're on your own drive in Warings Green, leave it where it stands.

Where the engine has run by now, stop somewhere safe then switch the vehicle off. Warings Green sits under a mile from the M42; on it, use the first exit. Tell us roughly how far it went: a run towards Birmingham, under 10 miles away, is a bigger job than a short hop across Warings Green.

What occurs when our technicians get there around Warings Green

Anywhere the car came to rest, whether by St Patricks Church of England Primary Academy, near St Patrick's or on your own drive, our van travels to it. Which fluid went in, the quantity, and if it ran: our technicians ask since those answers set the work and price. You get that price on the phone, before anyone heads out.

After that: draining, then a thorough flush of the whole system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither washes out unaided. Hence it counts more. Once the filter has been cleaned — or replaced, if needed — clean diesel goes in, and then the vehicle is tested. The engine is started next and checked to confirm it runs properly, all before our technicians go.

Most jobs are finished in about half an hour after our engineers arrive, as long as the motor has not run — and the pumps we 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. Before we get there, take a look at your insurance documents; many carry cover for misfuelling.
