A drain plus a thorough flush, done just where the vehicle sits in East Calder, is usually what it takes when caught before your engine runs. Not happened yet? Below, the page explains the why it takes place and the ways to prevent it for good. ## AdBlue in a diesel car, and its separate tank Many modern diesels on the roads round East Calder and Oakbank carry two liquids, not one. Diesel goes to the motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Separate tanks, different fillers. Other cars keep the AdBlue filler in the boot or under the bonnet; plenty more have the two together under one flap. Topping up your diesel side at the pump goes on constantly. The AdBlue side is filled far less regularly, usually from a bottle, and normally by somebody who has to stop and think where it goes. The mistake grows in the gap between the two. ## How AdBlue in your diesel tank takes place around East Calder Rarely is it carelessness: usually three things coincide. To start with, the warning. Low AdBlue brings a message from the car, and running dry leads to limp mode — hence a hurried top-up, perhaps before work off Main Street, or at The Grapes on the way home after work. Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand hits for the cap it would have used on the old one. A spout-topped bottle finds no resistance at a diesel filler any more than at an AdBlue one. So the tip, once begun, keeps on. The same few seconds settle it, in the middle of East Calder or out in Calderhall. ## Telling the AdBlue filler from the diesel filler A few seconds is all the checks take — so run through them before you tip anything, on a drive in Camps or a forecourt around East Calder. - Check the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually are not. - Check the size: the smaller filler neck is, on plenty of cars, the AdBlue one. - The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where. - In your boot or under the bonnet: that's where the filler is if it's not by your diesel cap, and the handbook tells you which. - Collecting a hire or company car, say at the car park outside Kirknewton? Ask the person who drove it last before you set off, not when the light comes on. ## Topping up AdBlue without it reaching your diesel tank Wherever in West Lothian the light comes on, here is a routine for the day. - Stop on level, motor off, with time to spare — never hurried on the side of Almondell Terrace. - Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap works — after you've found the filler and read it. - The two behind a single flap? So make sure the cap on the diesel filler is still shut ahead of lifting the bottle. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Before starting the car, close the cap and look a second time that your diesel cap never opened off. Find during the second or third stage that AdBlue went in the diesel tank? That is where you stop. Don't go on to stage five. ## East Calder: already put AdBlue in your diesel tank? Don't start the engine: that is how the short order of things begins. The fuel pump starts on many diesels the moment the ignition is switched on — so keep it off. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is drawn from — so don't top up with diesel to thin it. If you are at a forecourt, whether it's the Shell or the Asda, ask the staff to help push the vehicle clear of the petrol pump. On your own drive in East Calder? So your car stays where it is. Stop as soon as it is safe then switch off, if your motor has already run. East Calder lies under 3 miles from the M8; on it, use the first exit. Roughly how far did it go? Crossing East Calder is smaller a job than a run of under 15 miles towards Edinburgh, and so tell us. ## East Calder: what takes place when our engineers turn up The van reaches the vehicle anywhere it has come to rest — your own driveway, beside Past and Present, or outside the local primary school. Our technicians ask what got in, roughly how much, and whether it has run, because those answers settle this work and the price. No one sets off before you've heard our price over the phone. Emptying the tank comes next, followed by a thorough flush of the fuel system. Much more than with petrol, it counts here: the crystals build up, some metals corrode, and none of it washes out unaided, no matter how long it is left. Testing is last: before that, fresh diesel goes in, and the fuel filter is cleaned or replaced as needed. We do not go until it has been started and is running properly. Unstarted vehicles mostly mean a half-hour visit after the moment we arrive. The equipment is safe on a live filling station, and hushed enough for a residential street after dark. The insurer will ask for the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no deposit. Before we get there, take a look at your insurance documents; many carry cover for misfuelling. ## About East Calder itself East Calder is a village situated on the banks of the River Almond in West Lothian, with a mix of terraced housing and a population of around 1292 residents.
