In that case put this page aside for now, leave the ignition and motor off, and phone 0333 366 0103. A drain plus a full flush, carried out right where your car stands in Kenninghall, is usually all it takes when found before your motor runs. If you are reading before it has happened, the remainder of this page is about why it happens and how to make sure it doesn't. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of modern diesels around Quidenham, as well as Kenninghall, run on two fluids; your motor takes only your diesel. Kept in a tank of its own, AdBlue is fed into your exhaust gas and cleans it. There's a filler for each tank. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in at each filling station visit, again and again. Seldom topped up, AdBlue normally goes in from a bottle, tipped by a driver who has to stop and think which filler to use. The mistake grows in that gap between them. ## AdBlue in the diesel tank in Kenninghall: how it takes place Three things tend to come together, and carelessness is seldom one of them. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Market Place before work, or in the car park at The Red Lion on the way home. Unfamiliar vehicles come second, too. Hire cars, new vehicles and company motors put their fillers differently, and habit reaches for the cap used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. It takes a few seconds, be it in Dam Green or right in the centre of Kenninghall. ## Telling the AdBlue filler from your diesel filler Whether a Kenninghall forecourt or a driveway over in Guilt Cross, take a couple of seconds over these before any is poured in. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by position. - Plenty of motors give AdBlue the smaller filler of the two. - The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook shows which it lives when the filler is not next to your diesel cap: your boot, or under the bonnet. - The previous driver will know. Check as you collect a rental or fleet car — at Eccles Road's car park, say — not once the warning appears. ## Topping up AdBlue without it reaching your diesel tank The day the light comes on, anywhere around Norfolk, follow this routine. - Not in a rush on the side of Quidenham 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 name "AdBlue" aloud while unscrewing it. It sounds daft. It does the trick. - The two behind a single flap? Then make sure the cap on the diesel filler stays closed before lifting the bottle. - Gently is best, through the bottle's own spout, till it's full or the bottle runs out. - Before you start your car, close the cap and look a second time that the diesel cap was never opened off. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Never carry on to stage five. ## Already put AdBlue in your diesel tank around Kenninghall? What follows is a short order of things, starting with no starting the engine. Leave the ignition off as well, since on plenty of diesels it alone starts your fuel pump. Diluting it with more diesel won't work, because AdBlue sinks to the base rather than mixing — and that is where your fuel is drawn from. The staff at Esso, another forecourt nearby or any forecourt will usually help to push your car clear when asked. If you are on your own driveway around Kenninghall, leave the vehicle where it sits. Where your motor has been run already, stop safely and turn the vehicle off. Leave the M11 — under 50 miles out of Kenninghall — at the next junction. A short hop across Kenninghall is a smaller job than a run towards Norwich, under 25 miles away, so tell us about how far it went. ## Kenninghall: what takes place when our engineers get there The van comes to the car anywhere it stopped — your own driveway, near Kenninghall Village Hall, or by Kenninghall Primary School. The replies determine the work and our price, so our engineers ask what got in, about how much, and if it's run. You get that quote by phone, before anybody heads out. Next: a drain, then a full flush of the whole system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither clears away by itself. That is why it counts more. After the filter has been flushed — or renewed, where required — clean diesel is added, and finally the vehicle gets tested. Your engine is started next and checked to confirm it runs properly, all before we go. Unrun cars mostly mean a half-hour job from the moment we arrive. The equipment is fine on a busy filling station, and hushed enough for a driveway after dark. The insurer usually wants the engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. Many insurance policies include misfuelling cover, so it is worth checking yours while we are on the way. ## About Kenninghall Kenninghall is a rural village in the heart of Norfolk, situated approximately 18 miles south of Norwich and 80 miles northeast of London.
