Then set this page aside for now, keep the ignition and motor off, and ring 0333 366 0103. In Hill of Beath, catching it before the motor runs normally leaves a drain and a thorough flush where it stands. Not happened yet? Further down, the page explains the reasons it happens and the ways to avoid it for good. ## Why does AdBlue in a diesel vehicle need its own filler? No single liquid but two: that's how many newer diesels around Hill of Beath and Donibristle run, with diesel feeding your motor. AdBlue's own tank holds it, and from there it is sent to the exhaust, where spraying treats the gas. There is a filler for each tank. Plenty of vehicles have a single flap for both, whereas some put the AdBlue filler to your boot or under the bonnet. Diesel gets filled on every forecourt call-out, week in, week out. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and far less regularly. That gap is where the error lives. ## How does AdBlue in your diesel tank take place in Hill of Beath? Rarely is it carelessness: usually three things line up. On a drive off Swintons Place before work, or in the car park outside Silver Birch heading home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low your car warns you, and if it is empty, limp mode kicks in. Then your car is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one. Third, the spout goes in: a diesel filler or AdBlue filler, it slides in as easily, and after the pour begins, no part stops it. It's seconds, whether in Crossgates or right in the centre of Hill of Beath. ## Which filler is for AdBlue, and which for diesel? Check these first, on a forecourt around Hill of Beath or a driveway over in Cowdenbeath. Seconds, no more. - Blue and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not where it sits. - Check the size: the smaller filler neck is, on many vehicles, the AdBlue one. - A label inside your fuel flap frequently shows which fuel goes where, on plenty of motors. Check for it. - The handbook. If your filler is not by the diesel cap, it is in your boot or under the bonnet, and the handbook says which. - The previous driver will know. Check as you collect a rental or company car — at Cowdenbeath's car park, perhaps — rather than when the warning appears. ## Topping up AdBlue without it reaching the diesel tank The day the light comes on, anywhere in Fife, use this routine. - Not in a rush on the side of B981, not on a slope, not with the engine running: park and switch off first. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - The diesel cap remains on. Where both sit under a flap, make sure it's closed before lifting the bottle. - Stop once that tank is topped up or the bottle runs dry; until then, tip gently using the own spout. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the car. If at step two or three you find you have already poured into the diesel side, stop there. Don't go on to stage five. ## AdBlue in the diesel tank already, in Hill of Beath? Then the order of things is short. Don't start the engine. The fuel pump starts on plenty of diesels the moment your ignition is switched on — so leave it off. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from. The attendants at BP, Thames or any forecourt will normally lend a hand to push the vehicle away if you ask. Your own drive around Hill of Beath is the place it should stay. Already run? Stop once it is safe, then switch off. The next junction means the place to come off when you're on the M90, under a mile from Hill of Beath. A short hop across Hill of Beath is a smaller job than a run towards Dunfermline, under 5 miles away, and so tell us roughly how far it went. ## When we turn up around Hill of Beath, what happens? Our technicians come to your car wherever it has stopped, whether that is outside the local primary school, near Jim Baxter Statue or on your own driveway. Which liquid got in, the amount, and whether it ran: we ask because those answers set the work and price. During the call itself, you hear the quote — ahead of anything else. Emptying that tank comes next, followed by a thorough flush of the system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more with AdBlue than with petrol. Testing comes at the end: before that, fresh diesel is added, and the filter is flushed or replaced as needed. We do not go until it has been fired up and is running properly. Unrun cars usually need a half-hour job from the moment we arrive. The equipment is fine on a live forecourt, and quiet enough for a residential street after dark. No money upfront; you settle up on the day. At the end, the VAT invoice and the report from the engineer are handed to you for your insurer. It is worth checking your policy as the van travels to you: misfuelling cover comes with many policies. ## About Hill of Beath itself Hill of Beath is a suburban area situated on the banks of a river in Fife, with a mix of terraced housing and a relatively small population of around 1363 residents.
