Around Faifley, finding it before the engine turns normally leaves draining and a thorough flush on the spot. Nothing happened yet? Further down, the rest of the page covers the why it happens and the how to prevent it altogether. ## AdBlue in a diesel vehicle: two tanks, two fillers Plenty of modern diesels on the roads about Faifley and Drumry carry two liquids, not one. Diesel goes to the motor. Your exhaust, not the motor, is where AdBlue ends up: sprayed into the gas to clean it, from a separate tank. Every tank comes with one filler of its own. Other cars keep the AdBlue filler in your boot or under the bonnet; a lot more place the two side by side behind one flap. Topping up your diesel side at the petrol pump happens constantly. The AdBlue side is filled far less commonly, normally from a bottle, and usually by a person who has to stop and think where it goes. That gap is where the slip lives. ## How does AdBlue in your diesel tank occur in Faifley? It is hardly ever carelessness. Three things tend to line up. On a driveway off John Burnside Drive before work, or in the car park outside The Dublet on the way home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low the car warns you, and once it is gone, limp mode follows. The old car's filler is where the hand reaches — but a hire car, a new motor or a company car keeps the fillers elsewhere. That's a second factor: an unfamiliar car. Nothing stops the tip after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It's seconds, be it in Hardgate or right in the centre of Faifley. ## The AdBlue filler and your diesel filler: telling them apart Before you pour anything, whether on a drive in Kilbowie or a forecourt in Faifley, check these. They take a couple of seconds. - Read the cap instead of going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel ones normally are not. - Plenty of cars give AdBlue the smaller neck of the two. - The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where. - Cannot find it next to the diesel inlet? Then look beneath the bonnet or in your boot — the owner's manual says where. - Whoever had it before knows. Check as you pick up a hire car or company car — at Singer's car park, perhaps — not once the warning comes on. ## AdBlue top-ups that never reach the diesel tank On the day the warning comes on — anywhere it is across West Dunbartonshire — a simple routine to use. - Switch off once parked — flat ground, engine off, and not rushed beside Faifley Road at the roadside. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - The diesel cap remains on. When the two share a flap, make sure it's closed before the bottle comes up. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Close the cap, then check once more — confirm your diesel filler stayed closed throughout. After that, start the car. Stop there if you find, at stage two or three, that you've already poured into the diesel side. Stage five stays off limits. ## AdBlue in your diesel tank already, in Faifley? What follows is a short order of things, beginning with not starting your motor. Leave the ignition off as well, since on many diesels it alone runs the fuel pump. Filling up with diesel won't weaken it: rather than mixing, AdBlue sinks to the bottom of that tank, right where fuel is taken from. If you're on a forecourt, whether it is the Esso or the Jet, ask the staff to help roll the car away from the pump. Leave it where it is if you are on your own drive in Faifley. Already started? Stop once it's safe, then turn off. Leave the Toll Plaza Interchange — under 5 miles out of Faifley — at the next junction. Roughly how far did it go? Crossing Faifley is less work than a trip of under 10 miles towards Glasgow, so tell us. ## Our arrival in Faifley, and what happens next Our van comes to the vehicle anywhere it has come to rest — your own driveway, beside Faifley Parish Church, or by the local primary school. Which liquid went in, the amount, and whether it ran: we ask because those answers set both work and price. The quote is given on the call, before any van leaves. Draining that tank comes next, then a thorough flush of the system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. The filter cleaned or, where needed, swapped; clean diesel in; and then a check of your car. The engine is fired up next and checked to confirm it runs properly, all before we head off. If the engine has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. The insurer usually wants the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no money upfront. It's worth checking your insurance as the van travels to you: misfuelling cover is included with many policies. ## About Faifley itself Faifley is a suburban area situated on the riverside in West Dunbartonshire, with a mix of flat housing and local amenities.
