In that case set this page aside for now, leave the ignition and motor off, then call 0333 366 0103. Usually, if the engine hasn't turned, it is emptied and thoroughly purged where the vehicle is in West Farleigh. Reading before the event? Then the rest explains how it comes about and what to prevent it happening at all. ## AdBlue in a diesel motor, and its separate tank No single fluid but two: that's what many modern diesels around West Farleigh and Teston carry, with diesel for the motor. AdBlue's own tank holds it, and from there it goes to your exhaust, where spraying cleans the fumes. Separate tanks, different fillers. Other motors keep the AdBlue filler in the boot or under the bonnet; a lot of others place both side by side behind one flap. Diesel goes in at each forecourt call-out, again and again. Much less frequently, the AdBlue side gets filled — mostly from a bottle, by a person working out where it goes. The mistake lives in that gap. ## How does AdBlue in the diesel tank occur around West Farleigh? Three things tend to come together, and carelessness is rarely one of them. First, the warning. Low AdBlue triggers a warning from the car, and running dry means limp mode — so a rushed top-up, perhaps before work off Lower Road, perhaps outside The Tickled Trout on the way home after work. Next, the hand goes for the cap it would have used on the old motor — since a rental car, a new motor or a company car puts the fillers somewhere your last one didn't. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip once it has started. Whether it takes place in Hoppers Corner or the middle of West Farleigh, it is the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Before you pour anything, whether on a driveway in Livesey Street or a forecourt in West Farleigh, check these. They take a couple of seconds. - Where it sits can mislead; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps usually do not. - Look at 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 many vehicles. Look for it. - In the boot or under the bonnet: that is where your filler sits if it's not by your diesel cap, and the handbook tells you which. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Wateringbury, ask before you leave, not when the light comes on. ## Keeping AdBlue out of your diesel tank when you top up On the day the warning comes on — wherever it is around Kent — a simple routine to use. - Not in a rush on the side of Smith's Hill, not on a slope, not with the engine running: park then switch off properly. - Find the AdBlue filler, read the cap, and speak the word "AdBlue" aloud while you unscrew 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 — and leave it on. - Gently is best, through the bottle's own spout, until it is full or the bottle runs out. - Before starting your car, shut the cap and check a second time that the diesel cap was never opened off. Find at step two or three that it has already gone into the diesel side? So stop right there. Step five is out. ## Already put AdBlue in your diesel tank in West Farleigh? Do not start your motor: that's where the short order of things starts. On many diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from. The staff at JET, Esso or any forecourt will usually help pushing the vehicle away when asked. Your own driveway around West Farleigh is where it stays. If the engine has already run, stop as soon as it is safe and switch off. Leave the M20 — under 5 miles out of West Farleigh — at the first junction. Distance matters — a quick hop across West Farleigh is a smaller job than heading under 25 miles to Southend-on-Sea — so say about how far it went. ## West Farleigh: what takes place when we get there Our van reaches your car wherever it stopped — your own driveway, near Smith's Hall, or outside East Farleigh Primary School. Both the work and the price rest on three answers — what fluid, what amount, and whether it has run — so our technicians ask. Nobody sets off until you have had our quote over the phone. Emptying that tank comes next, followed by a full flush of your 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. After the fuel filter has been cleaned — or renewed, if needed — fresh diesel is added, and then the vehicle is tested. Before leaving, we start the car and make sure that it's running smoothly. If your motor has not run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. The insurer usually wants an engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. Misfuelling cover is part of many insurance policies — so make use of the wait to check yours. ## About West Farleigh itself West Farleigh is a small hamlet situated on the banks of the River Medway in Kent, with a low elevation of around 39 metres.
