AdBlue in a diesel car, and its separate tank

Many modern diesels on the roads about Hurst Green and Oxted carry two liquids, not one. Diesel goes to the motor. AdBlue's own tank keeps it, and from there it goes to your exhaust, and there spraying treats the fumes.

Every tank has one filler of its own. Other vehicles keep the AdBlue filler in the boot or under the bonnet; a lot of others place both side by side behind one flap. Diesel gets filled on each filling station call-out, week in, week out. Far less often, the AdBlue side gets filled — mostly from a bottle, by a person thinking about where it goes. The mistake grows in that gap between the two.

AdBlue in your diesel tank around Hurst Green: how it happens

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

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

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

A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the pour, once started, keeps on. Whether it happens in Holland or the middle of Hurst Green, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Hurst Green

The AdBlue filler and the diesel filler: telling them apart

Be it a Hurst Green forecourt or a drive out in Limpsfield, spend a couple of seconds on these before any goes in.

  • Where it sits can mislead; the cap doesn't. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps normally don't.
  • The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
  • The handbook says which it lives when the filler isn't next to the diesel cap: your boot, or under the bonnet.
  • Picking up a hire or company car, perhaps at the car park at the nearest station? Ask the person who drove it last before you set off, rather than once the light goes on.

Topping up AdBlue without it reaching the diesel tank

A routine for the day the light comes on, wherever around Surrey that is.

  • Switch off once parked — level ground, motor off, and never rushed by Oak Close on the verge.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, yes, yet it works.
  • Both under a single flap? Then confirm the cap on your diesel filler is still closed ahead of lifting the bottle.
  • Stop once your tank fills or the bottle is empty; before that, tip slowly using its built-in spout.
  • Only after that, start your car: close the cap, check again, and make sure your diesel cap was never opened.

Stop there if you find, at stage two or three, that you have already poured into your diesel side. Step five stays off limits.

AdBlue in your diesel tank already, in Hurst Green?

Don't start the engine: that is where the short order of things begins. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is sucked from.

Ask the staff to help roll the car away from the pump if you're at a forecourt — the Esso, the Shell or somewhere else. At home around Hurst Green? So the vehicle stays put.

If your engine has already run, stop as soon as it is safe then switch off. Come off the M25 — under 3 miles out of Hurst Green — at the first exit. Tell us about how far it went: a run towards Westminster, under 25 miles away, is a bigger job than a short hop across Hurst Green.

What takes place when we arrive in Hurst Green

By Hurst Green Infant School, near Hurst Green Community Centre or on your own driveway: wherever the vehicle has stopped, our technicians come to it. Which liquid was put in, the amount, and whether it ran: our engineers ask because those replies decide both work and quote. That quote comes on the call, ahead of any van leaving.

Your system is then cleaned thoroughly, after your tank is cleared. 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 your filter is flushed — or renewed, if required — clean diesel is added, and then your vehicle is tested. Before we go, our technicians fire it up and make sure that it's running properly.

Using pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run take about half an hour after our engineers are there. Payment happens on the day, not upfront, and you are given the documents your insurer wants: an engineer's report and a VAT invoice. Wrong-fuel cover is included in many insurance policies — and so use the wait to look at yours.
