Normally, if the engine has not run, it's drained and thoroughly flushed where the vehicle sits in Bridge. The remainder of this page explains why it occurs and how to make sure it doesn't — useful if you are reading ahead of time. ## AdBlue in a diesel car, and its separate tank Many current diesels on the roads round Bridge and Bishopsbourne carry two liquids, not one. Diesel goes to the motor. Its own tank keeps it, and from there it is sent to your exhaust, and there a spray treats the gas. Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Topping up the diesel side at the petrol pump goes on constantly. Far less frequently, the AdBlue side gets filled — mostly from a bottle, by a person thinking about where it goes. It's in that gap that the error lives. ## How does AdBlue in the diesel tank take place in Bridge? Carelessness seldom causes it. Instead is three things coming up together. The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off High Street before work, or in the car park outside The Bridge Arms on the way home. Unfamiliar cars come next, as well. Hire cars, new cars and company motors place their fillers differently, and the hand goes for the cap it used on the old one. No part halts the tip once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Bridge or out in Patrixbourne. ## Which filler is for AdBlue, and which for diesel? Whether a Bridge forecourt or a driveway out in Nackington, take a couple of seconds on these before anything goes in. - Position can mislead; the cap does not. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel ones normally do not. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook says which it is if your filler is not next to your diesel cap: your boot, or under the bonnet. - Whoever had it before will know. Check as you pick up a hire car or fleet car — from Bekesbourne's car park, say — not when the light appears. ## Keeping AdBlue out of your diesel tank when you top up Wherever around Kent the light comes on, this is a routine for the day. - Not in a rush on the side of Dering Road, not on a slope, not with your motor running: park and switch off properly. - Find the AdBlue filler, check the cap, and say the word "AdBlue" out loud while unscrewing it. It sounds daft. It does the trick. - Both under a single flap? So confirm the cap on the diesel filler is still shut ahead of raising the bottle. - Finish once that tank fills or the bottle runs dry; until then, pour gently through its built-in spout. - Close the cap and check again. Make sure your diesel cap was never opened. Only then start the vehicle. Stop there if you find, at step two or three, that you've already poured into the diesel side. Never go on to step five. ## Already put AdBlue in your diesel tank around Bridge? What follows is a short order of things, beginning with no starting the engine. The fuel pump runs on plenty of diesels as soon as your ignition is switched on — and so keep it off. AdBlue does not 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. The staff at Esso, Asda or any forecourt will normally lend a hand to push the car away if asked. Your own driveway in Bridge is where it stays. Already run? Pull over once it's sensible, then switch off. On the M2, under 10 miles from Bridge, that means the next exit. Mileage counts — a quick hop across Bridge is a smaller job than driving under 5 miles to Canterbury — so tell us about how far it went. ## When we arrive around Bridge, what occurs? Our van reaches the vehicle wherever it has come to rest — your own drive, beside Bridge Village Hall, or outside Bridge and Patrixbourne Church of England Primary School. The answers decide the work and our quote, and so our technicians ask what went in, roughly how much, and if it's run. The price comes on the call, ahead of any van leaving. Next: draining, then a thorough flush of the entire 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. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. We don't go until it has been started and is running smoothly. Unstarted vehicles usually mean a half-hour job from the moment we arrive. The equipment is fine on a busy forecourt, and hushed enough for a driveway after dark. Payment is on the day, not upfront, and you receive the documents your insurer asks for: an engineer report and a VAT invoice. Before we get there, take a look at your policy; plenty include cover for misfuelling. ## About Bridge, for a moment Bridge is a village situated on the River Stour in Kent, with a riverside setting and an elevation of around 30 metres.
