Pause reading for a moment if your diesel tank already holds AdBlue in it: ignition off, engine off, then phone 0333 366 0103. Usually, if the engine hasn't turned, it is drained and thoroughly purged where your car sits around Parkeston. If you are reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel car Many newer diesels around Outer Part of Town Westward, as well as Parkeston, run on two liquids; the motor takes only your diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Every tank has one filler of its own. Some cars keep the AdBlue filler in the boot or under the bonnet; plenty more have both side by side behind one flap. At the pump, the diesel side is topped up constantly. The AdBlue side is topped up far less often, usually from a bottle, and usually by someone who has to stop and think where it goes. It's in the gap that the slip happens. ## Parkeston: how AdBlue in your diesel tank happens Three things tend to line up, and carelessness is seldom one of them. Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Adelaide Street, or on the way home in the car park outside Fryatt Hotel & Bar. Unfamiliar cars are next, as well. Hire cars, new vehicles and company vehicles place their fillers differently, and the hand reaches for the cap it used on the old one. A spouted bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, after started, carries on. Whether it takes place in Upper Dovercourt or the middle of Parkeston, it's the same few seconds. ## Telling the AdBlue filler from your diesel filler Before you tip anything, whether on a driveway in Bath Side or a forecourt around Parkeston, check these. They take a couple of seconds. - The cap. The AdBlue cap is often blue, or marked "AdBlue". Your diesel cap usually is not. Read it instead of going by where it sits. - Many vehicles fit AdBlue the smaller filler of the two. - The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook. If your filler is not by your diesel cap, it is in the boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Harwich International, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank A routine for the day the light comes on, wherever around Essex that is. - Stop somewhere level, motor off, with time to spare — not hurried on the side of Una Road. - Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud as you unscrew it. It seems silly. It does the trick. - The diesel cap stays on. Where the two share a flap, confirm it is shut before the bottle comes up. - Stop once the tank is topped up or the bottle is empty; until then, pour slowly through the built-in spout. - Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the vehicle. If at stage two or three you find you have already poured into your diesel side, stop there. Never go on to stage five. ## Already put AdBlue in your diesel tank around Parkeston? Short order, then. First: the motor remains unstarted. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from. If you are at a forecourt, whether it's the Morrisons or the Texaco, ask the staff to help roll your car clear of the pump. Your own driveway around Parkeston is where it should stay. If the motor has already run, stop as soon as it is safe then switch off. Come off the M11 — under 50 miles out of Parkeston — at the first junction. About how far did it go? Hopping across Parkeston is less a job than a trip of under 25 miles towards Colchester, so tell us. ## What occurs when our engineers get there in Parkeston Anywhere your car came to rest, whether by Spring Meadow Primary School & Nursery, near Parkeston Village Sign or on your own drive, the van comes to it. What fluid was put in, the amount, and if it ran: we ask since those answers decide both work and price. That price is given on the call, ahead of any van leaving. Your system is then cleaned thoroughly, after that tank is cleared. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Next we start it and confirm it runs properly before leaving. With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run take roughly half an hour once our engineers are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, have a look at your insurance documents; plenty include cover for misfuelling. ## About Parkeston Parkeston is a small coastal village in Essex, situated near the mouth of the River Stour and close to the nearby settlements of Upper Dovercourt and Dovercourt.
