Then put this page down a moment, keep the ignition and motor off, and phone 0333 366 0103. A drain and a full flush, carried out right where the vehicle sits around Finglassie, is usually what it takes if found before the motor runs. Here in advance? In that case what follows covers why it happens and how to prevent it happening at all. ## Two fillers, two tanks: AdBlue in a diesel motor Diesel feeds your motor — but many newer diesels driven round Finglassie and Rimbleton carry a second fluid as well. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it. Each tank has a filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel gets filled at each filling station visit, again and again. Far less regularly, the AdBlue side gets filled — mostly from a bottle, by someone working out where it goes. Mistakes happen in the gap between the two. ## How does AdBlue in your diesel tank take place in Finglassie? Rarely is it carelessness: normally three things coincide. Haste follows from the warning. The vehicle tells you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Courthill Drive, or on the way home in the car park outside Foxton Bar & Grill. The old car's filler is where the hand goes — but a rental car, a new motor or a company car puts the fillers elsewhere. That's the second factor: an unfamiliar car. Third, the bottle fits: diesel filler or AdBlue filler, it slides in as readily, and after the tip starts, no part stops it. It takes seconds, be it out in Stenton or bang in the heart of Finglassie. ## How to tell the AdBlue filler from the diesel one Whether a Finglassie forecourt or a driveway over in Eastfield, spend a couple of seconds on these before any is poured in. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap usually is not. Read it rather than going by where it sits. - Plenty of motors fit AdBlue the smaller filler of the two. - Open the filler flap and look for a label — many vehicles show what belongs in each inlet just there. - The handbook. If the filler isn't by your diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Glenrothes with Thornton. ## AdBlue top-ups that never reach your diesel tank A routine for the day the light comes on, wherever across Fife that is. - Stop on level, motor off, with time to spare — not rushing on the side of Kinnaird Close. - Find the AdBlue filler, read the cap, and speak the word "AdBlue" aloud while unscrewing it. It seems silly. It does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on. - Stop once your tank fills or the bottle is empty; before that, pour gently through its 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 the second or third stage that the bottle went in the wrong tank? That's where you stop. Leave out step five entirely. ## AdBlue in the diesel tank already, around Finglassie? Do not start the motor: that's how the short order of things starts. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Thinning it with more diesel fails, since AdBlue sinks to the bottom rather than mixing — and that's where your fuel is sucked from. On a forecourt — BP, Shell or any other — the staff will normally help push the vehicle clear, when you ask. Leave it where it is if you're on your own drive in Finglassie. Already run? Stop when it is sensible, then switch off. Finglassie lies under 10 miles from the M90; on it, take the first exit. A short hop across Finglassie is a smaller job than a run towards Dunfermline, under 15 miles away, so tell us roughly how far it went. ## What takes place when our technicians get there around Finglassie The van comes to the car wherever it stopped — your own driveway, beside UFOs, or by the local primary school. Both the work and the price rest on three answers — which liquid, what amount, and if it has run — so we ask. You get that quote on the phone, before anybody heads out. The fuel system is then purged thoroughly, once that tank is cleared. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and none of it clears out unaided. That is why it counts more. After the filter has been cleaned — or replaced, if needed — clean diesel is added, and then the car is tested. Then we fire it up and make sure it runs smoothly before we leave. Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where your engine has not run need roughly half an hour after we are there. Your insurer will ask for an engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. It's worth looking at your insurance as the van travels to you: misfuelling cover is included with plenty of policies. ## About Finglassie itself Finglassie is a suburban area situated on the riverside in Fife, with a mix of detached housing and a relatively low elevation of 67 metres.
