Rose Hill: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

AdBlue already in the diesel tank? Then put this page aside a moment, keep your ignition and motor off, then phone 0333 366 0103. Caught before the engine runs, it is usually a drain and a thorough flush, done where your car is in Rose Hill. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it doesn't.

Why does AdBlue in a diesel car need its own filler?

Not one fluid but two: that is what many newer diesels near Rose Hill and Stoke run, with diesel feeding the engine. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has its own filler. Some motors keep the AdBlue filler in your boot or under the bonnet; a lot of others have both together under one flap. At the petrol pump, your diesel side is topped up all the time. Rarely filled, AdBlue normally comes out of a bottle, poured by someone who has to stop and think which filler to use. The mistake grows in that gap between the two.

How does AdBlue in your diesel tank happen around Rose Hill?

Carelessness seldom explains it. Instead is three things coming up at once.

On a drive off Alan Road before work, or in the car park at Margaret Catchpole heading home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low the vehicle tells you, and once it is gone, limp mode follows.

The old car's cap is where your hand reaches — but a rental car, a new motor or a company car keeps the fillers elsewhere. That is a second thing: a strange car.

No part halts the pour once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Rose Hill or out in California.

Flushing a diesel fuel system after AdBlue, Rose Hill

Which filler is for AdBlue, and which for diesel?

Be it a Rose Hill forecourt or a driveway out in Gainsborough, spend a couple of seconds over these before anything is poured in.

  • Read the cap rather than going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel ones normally aren't.
  • Look at the size: the smaller filler neck is, on many vehicles, the AdBlue one.
  • A label inside the fuel flap frequently says which fuel goes where, on many cars. Look for it.
  • Cannot see it beside your diesel filler? In that case check beneath the bonnet or inside your boot — the handbook will say where.
  • Ask 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 Derby Road.

Keeping AdBlue out of your diesel tank when you top up

The day the light goes on, wherever around Suffolk, follow this routine.

  • Turn off after you park — level ground, engine off, and never rushed by Elmhurst Drive at the roadside.
  • Locate the AdBlue filler, check the cap, and say the name "AdBlue" out loud while unscrewing it. It sounds daft. It does the trick.
  • The diesel cap remains on. When the two sit under a flap, make sure it is closed before lifting the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.

Stop there if you find, at stage two or three, that you've already poured into your diesel side. Step five stays out.

Rose Hill: already put AdBlue in your diesel tank?

Don't start your motor: that's how the short order of things begins. Leave your ignition off as well, since on many diesels switching it on alone runs your fuel pump. Diluting it with more diesel won't work, since AdBlue settles to the bottom rather than mixing — and that's where the fuel is drawn from.

If you are at a forecourt, whether it's the BP or the Applegreen, ask the staff to help roll your car away from the petrol pump. On your own drive around Rose Hill? So the car remains put.

Stop as soon as it is safe and switch off, if your motor has already run. The next exit means the place to leave if you are on the M11, under 50 miles from Rose Hill. Tell us about how far it went: a run towards Colchester, under 25 miles away, is a bigger job than a short hop across Rose Hill.

What occurs when our engineers turn up in Rose Hill

By Rose Hill Primary, close to Hatfield Road Congregational Church or on your own drive: wherever the vehicle has stopped, our technicians come to it. Which fluid got in, the amount, and if it ran: our engineers ask because the replies set the work and quote. That quote is given over the phone, ahead of any van leaving.

Then your tank is drained and the system purged thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more here than with petrol. Filter flushed or, where needed, swapped; fresh diesel in; and then a check of your vehicle. We do not leave until it has been started and 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 after dark. No money in advance; you settle up that day. Afterwards, the VAT invoice and the report from the engineer go to you for the insurer. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.

AdBlue drains about Rose Hill, and Suffolk beyond

Racecourse and Greenwich are among the places near Rose Hill, a residential suburb, that the same teams cover, over IP postcodes. Quickest of all: give a IP3 0 postcode to the van.

The vehicle does not need to shift. A drive, a lay-by on the way to Holywells Park, a side street close to St Bartholomew's Church: our engineers drain the car where it stands. Ring and ask rather than guessing if you are near a border, or somewhere hard to describe, like the back of Alan Road Methodist Church.
