Mountblow: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
AdBlue already in your diesel tank? Then put this page aside a moment, leave your ignition and motor off, and phone 0333 366 0103. A drain plus a full flush, carried out just where your car sits around Mountblow, is normally all it takes when caught before your engine runs. If you're reading before it has happened, the rest of this page is about why it occurs and how to make sure it doesn't.
AdBlue in a diesel vehicle: two tanks, two fillers
Plenty of current diesels on the roads round Mountblow and Clydebank carry two liquids, not one. Diesel goes to your motor. The exhaust, not the motor, is where AdBlue ends up: dosed into the gas to fresh them, from a separate tank.
Each tank comes with one filler of its own. Plenty of motors share a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet. The diesel side is filled at the petrol pump all the time. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and far less regularly. The mistake grows in the gap between them.
AdBlue in your diesel tank around Mountblow: how it occurs
Carelessness seldom causes it. What does is three things coming up at once.
On a driveway off Mountblow Road before work, or in the car park at The Mountblow heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it is empty, limp mode kicks in.
Then the vehicle is new. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one.
Third, the bottle goes in: diesel filler or AdBlue one, it slides in just as easily, and once the pour starts, nothing stops it. Whether it happens in Dalmuir or the middle of Mountblow, it is the same few seconds.
Telling the AdBlue filler from your diesel filler
Before you tip anything, whether on a drive in Erskine Harbour or a forecourt around Mountblow, check these. They take a few seconds.
- Position misleads; the cap doesn't. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel caps usually do not.
- Many motors give AdBlue the smaller neck of the two.
- The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where.
- Can't see it beside the diesel inlet? Then look beneath the bonnet or inside your boot — the owner's manual says where.
- Picking up a hire or company car, say at the car park at Dalmuir? Ask the person who drove it last before you set off, not once the light goes on.
Topping up AdBlue without it reaching your diesel tank
A routine for the day the light comes on, wherever around West Dunbartonshire that is.
- Turn off once parked — level ground, motor off, and not rushed by Kimberley Street at the roadside.
- Silly as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — after you've located your filler and read the cap.
- The diesel cap remains on. When the two share a flap, make sure it is shut before the bottle comes up.
- Finish when the tank fills or the bottle runs dry; until then, pour slowly using the own spout.
- Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car.
Find at stage two or three that it's already gone into your diesel side? So stop right there. Stage five stays out.
Mountblow: already put AdBlue in the diesel tank?
The short order of things, starting with no starting the engine. Keep your ignition off too, since on many diesels switching it on by itself runs the pump. Filling up with diesel will not weaken it: instead, AdBlue drops to the bottom of the tank, right where the fuel is taken from.
On a forecourt — JET, Henry's or any other — the staff will normally help roll the car clear, when you ask. Leave it where it is if you are on your own driveway around Mountblow.
If the motor has already run, stop as soon as it is safe then switch off. Come off the Toll Plaza Interchange — under 3 miles out of Mountblow — at the first exit. Roughly how far did it go? Hopping across Mountblow is less work than a run of under 10 miles to Glasgow, and so tell us.
What takes place when our technicians turn up around Mountblow
Our technicians come to the vehicle wherever it has stopped, whether that's outside the local primary school, close to Auchentoshan Distillery or on your own driveway. What liquid was put in, the amount, and whether it ran: our engineers ask because the replies decide the work and quote. You get that price by phone, before anyone heads out.
The system is then purged thoroughly, once that 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 does not wash out on its own. Testing comes last: before that, clean diesel goes in, and your filter is cleaned or replaced as needed. Before we go, our engineers fire it up and make sure that it is running smoothly.
Unstarted vehicles mostly need a half-hour visit after the moment we arrive. The equipment is safe on a live forecourt, and hushed enough for a residential street after dark. Payment happens on the day, not upfront, and you are given the documents your insurer wants: an engineer report and a VAT invoice. It is worth checking your policy as the van travels to you: misfuelling cover is included with plenty of policies.
