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

AdBlue already in your diesel tank? In that case set this page aside a moment, leave the ignition and motor off, then phone 0333 366 0103. A drain and a full flush, carried out right where your vehicle stands around Poll Hill, is usually all it needs when found before the engine runs. If you are 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, and its separate tank

No single fluid but two: that's what plenty of modern diesels around Poll Hill and Irby carry, with diesel feeding your motor. Stored in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it.

There is a filler on every tank. Under one flap, side by side: that is the layout on a lot of motors. On others, AdBlue's filler sits under the bonnet or in your boot instead. The diesel side is topped up at the pump all the time. The AdBlue side is fuelled far less often, normally from a bottle, and usually by someone who has to stop and think where it goes. The mistake lives in that gap.

How AdBlue in the diesel tank takes place around Poll Hill

Rarely is it carelessness: normally three things coincide.

Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Tower Road South, or on the way home in the car park outside The Harvest Mouse.

Then your car is strange. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have used on the old one.

Nothing halts the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Heswall or the middle of Poll Hill: it takes the same few seconds in both.

How to tell the AdBlue filler from the diesel one

A couple of seconds is all these take — so check them before you pour anything, on a drive in Gayton or a forecourt in Poll Hill.

  • Position can mislead; the cap does not. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel ones normally do not.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • Check inside the fuel flap: plenty of motors have a label there saying which fuel goes where.
  • Cannot find it next to your diesel filler? In that case check below the bonnet or in the boot — the owner's manual says where.
  • Whoever had it before will know. Ask as you collect a hire car or company car — from Heswall's car park, perhaps — rather than once the light appears.

Keeping AdBlue out of your diesel tank when you top up

A routine for the day the light comes on, wherever across Merseyside that is.

  • Pull in somewhere level, motor off, with time in hand — never rushing on the side of Quarry Road East.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Gently is best, through the bottle's own spout, till it's full or the bottle is empty.
  • Before starting your car, shut the cap and look again that your diesel cap was never came off.

If at stage two or three you find you have already poured into the diesel side, stop there. Step five stays off limits.

Poll Hill: already put AdBlue in your diesel tank?

Do not start your motor: that's where the short order of things starts. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where your fuel is drawn from — so do not top up with diesel to thin it.

Ask the attendants to help roll your car clear of the pump if you are on a forecourt — the Texaco, the Shell or somewhere else. Leave it where it is if you are on your own drive in Poll Hill.

Stop as soon as it is safe and switch off, if the motor has already run. On the M53, under 3 miles from Poll Hill, that means the next exit. Tell us about how far it went: a run towards Liverpool, under 10 miles away, is a bigger job than a short hop across Poll Hill.

What takes place when our engineers turn up in Poll Hill

Outside Ladymount Catholic Primary School, near Kylemore Community Centre or on your own driveway: wherever the car has stopped, our technicians come to it. Both the work and the price rest on three replies — which fluid, which amount, and if it's run — so our technicians ask. That quote is given on the call, before any van leaves.

Then that tank is emptied and your system purged thoroughly. Much more than with petrol, it matters here: the crystals build up, some metals corrode, and nothing washes out on its own, no matter how long it sits. Filter cleaned or, if needed, replaced; clean diesel in; then a test of your vehicle. Before leaving, we fire it up and make sure that it is running properly.

Unstarted vehicles usually mean a half-hour job after the moment we arrive. The equipment is fine on a busy filling station, and hushed enough for a residential street late at night. 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 — and so make use of the wait to look at yours.

About Poll Hill, briefly

Poll Hill is a suburban area on the Wirral Peninsula in Merseyside, situated near the coast and approximately 7 miles from Liverpool. Poll Hill sits at an elevation of around 102 metres, overlooking the surrounding landscape. Poll Hill is characterized by its predominantly semi-detached housing stock, which reflects the typical residential development of the region. Poll Hill is close to nearby places such as Heswall, Pensby, and Lower Village, and is about 178 miles northwest of London.

Poll Hill and Merseyside: AdBlue drains across the area

Poll Hill is a residential suburb, and our teams that cover it also work the towns around it, Pensby and Lower Village among them, across the CH postcode area. Quickest of all: give a CH60 6 postcode to the van.

The vehicle does not need to shift. Our engineers drain it where it is — a side street near Church of the Good Shepherd, a lay-by on the way to the green space at the edge of the village, a driveway. Guessing won't help at the back of Heswall Library, close to a border, or somewhere awkward to pin down; phone and check.
