Then set this page down a moment, leave your ignition and engine off, and phone 0333 366 0103. In Clerkhill, catching it before the motor turns normally means draining and a thorough flush where it stands. Nothing happened yet? Below, the rest of the page explains the why it occurs and the how to avoid it for good. ## AdBlue in a diesel vehicle: two tanks, two fillers No single liquid but two: that's what many newer diesels near Clerkhill and Blackhouse run, with diesel feeding the motor. Its own tank holds it, and from there it is sent to the exhaust, and there spraying treats the gas. Each tank has its own filler. Some cars put the AdBlue filler in the boot or under the bonnet; plenty more place both together behind one flap. Diesel goes in at every forecourt call-out, week in, week out. Far less frequently, the AdBlue side gets topped up — normally from a bottle, by someone thinking about where it goes. That gap is where the mistake lives. ## How does AdBlue in the diesel tank take place in Clerkhill? Three things tend to line up, and carelessness is rarely one of them. Haste comes from the warning. The vehicle warns you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Eden Drive, or on the way home in the car park at Grange Inn. Next, the hand reaches for the cap it knew on the old vehicle — because a hire car, a new vehicle or a company car places the fillers where your last one didn't. Third, the spout goes in: diesel filler or AdBlue one, it goes in as readily, and once the tip begins, no part halts it. It's seconds, be it in Grange Gardens or right in the heart of Clerkhill. ## How to tell the AdBlue filler from the diesel one A few seconds is all these take — so run through them before you pour anything, on a driveway in Coplandhill or a forecourt in Clerkhill. - Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position. - Look at the size: the smaller filler neck is, on plenty of cars, the AdBlue one. - Look inside the fuel flap: many vehicles carry a label there showing which fuel goes where. - The handbook shows which it is if the filler is not next to your diesel cap: your boot, or under the bonnet. - Collecting a hire or company car, say at the car park outside the nearest station? Ask whoever drove it last before leaving, not when the light goes on. ## Keeping AdBlue out of your diesel tank when you top up On the day the warning appears — wherever you are across Aberdeenshire — a simple routine to use. - Stop somewhere level, motor off, with time to spare — not rushing on the side of Copeman Avenue. - Locate the AdBlue filler, read the cap, and speak the name "AdBlue" out loud as unscrewing it. It sounds silly. It works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the vehicle on. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Shut the cap, then check once more — making sure your diesel filler stayed shut the whole time. After that, start the car. Find at step two or three that it's already gone into your diesel side? Then stop just there. Don't go on to stage five. ## Clerkhill: already put AdBlue in the diesel tank? Short list, then. Top of it: your motor stays unstarted. Leave the ignition off as well, because on plenty of diesels it by itself starts your pump. Thinning it with extra diesel won't work, because AdBlue settles to the base rather than mixing — and that is where the fuel is pulled from. Ask the attendants to help roll the car clear of the pump if you are on a forecourt — the Esso, the Asda or anywhere else. Leave it where it is if you're on your own drive around Clerkhill. Already run? Pull over when it's safe, then turn off. Clerkhill sits over 50 miles from the M90; there, use the next exit. A short hop across Clerkhill is a smaller job than a run towards Aberdeen, under 50 miles away, and so tell us roughly how far it went. ## Clerkhill: what takes place when we turn up Anywhere your car came to rest, be it by the local primary school, beside c or at home, our van travels to it. Our engineers ask what was put in, about how much, and if it's run, because the answers settle the work and the price. The quote comes on the call, ahead of any van leaving. After that: draining, then a thorough flush of the whole system. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and none of that washes away by itself. Hence it counts more. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Before we go, our engineers start the engine and make sure that it's running smoothly. Unstarted vehicles mostly mean a half-hour visit after arrival. The kit is safe on a live forecourt, and quiet enough for a residential street after dark. Payment is on the day, not upfront, and you receive the paperwork your insurer wants: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way. ## About Clerkhill and where it is Clerkhill is a suburban area in Aberdeenshire, situated near the coast at an elevation of 26 metres.
