AdBlue in a diesel vehicle, and its separate tank

Many newer diesels in Pollok, as well as Priesthill, run on two fluids; your motor takes just the diesel. Your exhaust, not your motor, is where AdBlue goes: sprayed into the fumes to fresh them, from a separate tank.

Different tanks, separate fillers. Plenty of motors share a single flap for both, while some put the AdBlue filler to the boot or under the bonnet. At the petrol pump, your diesel side is topped up all the time. Someone who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and much less regularly. The mistake grows in the gap between the two.

Priesthill: how AdBlue in the diesel tank occurs

It's rarely carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Dunside Drive before work, or in the car park outside the pub in the village on the way home.

New-to-you motors are second, as well. Rentals, new vehicles and company vehicles put their fillers in new places, and habit reaches for the cap it used on the old one.

A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. So the pour, once started, carries on. The same few seconds decide it, in the middle of Priesthill or out in South Nitshill.

Flushing a diesel fuel system after AdBlue, Priesthill

Which filler is for AdBlue, and which for diesel?

Look at these first, on a forecourt around Priesthill or a driveway over in Hurlet. Seconds, that's all.

  • Blue and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits.
  • Many vehicles fit AdBlue the smaller neck of the two.
  • Look inside the fuel flap: plenty of motors have a label there showing which fuel goes where.
  • In your boot or under the bonnet: that is where your filler is if it is not by the diesel cap, and the handbook says which.
  • The previous driver will know. Ask when you pick up a hire car or fleet car — from Nitshill's car park, perhaps — not when the warning appears.

How to top up without AdBlue in your diesel tank

On the day the light appears — anywhere you are around Glasgow City — a simple routine to use.

  • Stop somewhere level, engine off, with time to spare — not hurried on the side of Peat Road.
  • Find the AdBlue filler, read the cap, and say the name "AdBlue" out loud as you unscrew it. It sounds silly. It does the trick.
  • Both under a single flap? So confirm the lid on the diesel side is still shut before lifting the bottle.
  • Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Close the cap, and check again — confirm the diesel filler stayed shut the whole time. Only then, start the car.

Stop there if you find, at stage two or three, that you have already poured into the diesel side. Skip stage five entirely.

AdBlue in the diesel tank already, in Priesthill?

Then the order of things is short. Do not start the engine. Leave the ignition off as well, because on plenty of diesels it by itself starts your fuel pump. Topping up with diesel won't weaken it: rather than mixing, AdBlue sinks to the bottom of your tank, just where the fuel is taken from.

Ask the attendants to help roll your car away from the pump if you're on a forecourt — the Esso, the Tesco or somewhere else. Your own driveway around Priesthill is the place it stays.

If your engine has already run, stop as soon as it is safe then switch off. On the M77, under a mile from Priesthill, that means the next exit. Distance matters — a quick hop across Priesthill makes a smaller job than driving under 10 miles to Glasgow — so say roughly how far it went.

Priesthill: what occurs when our technicians turn up

Anywhere your car came to rest, be it outside the local primary school, beside St Robert Bellarmine RC Church or on your own drive, the van comes to it. The replies decide the work and our quote, so our technicians ask what got in, roughly how much, and if it's run. During the call itself, you are told the price — ahead of dispatch.

Emptying the tank comes next, then a thorough flush of your system. Much more than with petrol, it counts here: crystals build up, some metals are attacked, and none of that clears out unaided, however long it sits. The filter cleaned or, where needed, swapped; clean diesel in; then a test of the car. After that our engineers start the car and check it runs correctly before we go.

Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which the motor hasn't run take roughly half an hour once our engineers arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is part of many insurance policies — so use the wait to look at yours.

There's no need to shift the car. Draining takes place right there, whether a driveway, a street near War Memorial, or a layby on the way to Househill Park. Awkward to explain, like the back of Nitshill Colliery Disaster Memorial? By a border? Asking is better than guessing, so ring.
