A drain and a full flush, carried out right where your vehicle stands in Morchard Bishop, is usually all it takes when found before your motor runs. The remainder of this page covers why it happens and how to make sure it does not — useful if you are reading ahead of time. ## AdBlue in a diesel car, and its separate tank Many modern diesels on the roads around Morchard Bishop and Eastington carry two liquids, not one. Diesel goes to the engine. Its own tank holds it, and from there it goes to the exhaust, and there spraying cleans the gas. Different tanks, separate fillers. 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. The diesel side is filled at the petrol pump all the time. Far less commonly, the AdBlue side gets filled — mostly from a bottle, by a person thinking about where it goes. That gap is where the error lives. ## Morchard Bishop: how AdBlue in your diesel tank takes place It's seldom carelessness. Three things tend to line up. First, the warning. Low AdBlue triggers a warning from your car, and letting it run out means limp mode — hence a hurried top-up, perhaps before work off Church Street, perhaps outside London Inn on the way home that evening. The old car's filler is where the hand goes — but a hire car, a new vehicle or a company car keeps the fillers elsewhere. That is a second thing: a strange vehicle. Nothing halts the pour once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it happens in Frost or the middle of Morchard Bishop, it is the same few seconds. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all the checks take — so run through them before you pour anything, on a drive in Morchard Road or a forecourt around Morchard Bishop. - Blue and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally does not. Go by the cap, not where it sits. - The size. On many motors the AdBlue filler neck is the smaller of the two. - The flap. Look inside your fuel flap for a label. Many vehicles say there which fuel goes where. - In your boot or under the bonnet: that is where the filler sits if it is not by your diesel cap, and the handbook tells you which. - The previous driver will know. Check as you collect a hire car or fleet car — at Morchard Road's car park, perhaps — rather than when the light appears. ## Keeping AdBlue out of the diesel tank when you top up A routine for the day the light comes on, wherever across Devon that is. - Not in a rush on the side of Chapel Street, not on a slope, not with your engine running: park and switch off properly. - Locate the AdBlue filler, check the cap, and say the name "AdBlue" aloud while unscrewing it. It sounds daft. It does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on. - Slowly does it, through the bottle's own spout, until it is full or the bottle is empty. - Only after that, start the car: close the cap, check again, and make sure your diesel cap was never opened. If at stage two or three you find you have already poured into your diesel side, stop there. Never go on to step five. ## Put AdBlue in the diesel tank around Morchard Bishop already? What follows is a short order of things, starting with not starting your engine. Leave your ignition off as well, since on plenty of diesels it alone runs the fuel pump. Thinning it with extra diesel won't work, because AdBlue sinks to the bottom rather than blending — and that's where your fuel is drawn from. If you're on a forecourt, whether it's the Lapford Jet or the another forecourt nearby, ask the attendants to help push the car away from the pump. If you are on your own driveway in Morchard Bishop, leave it where it sits. Stop as soon as it is safe and switch off, if your motor has already run. Morchard Bishop sits under 15 miles from the M5; there, use the first junction. Roughly how far did it go? Crossing Morchard Bishop is less work than a run of under 15 miles towards Exeter, so say. ## Our arrival around Morchard Bishop, and what takes place next Our engineers come to the vehicle wherever it has stopped, whether that's outside Morchard Bishop Church of England Primary School, close to St Mary the Virgin or on your own driveway. Both the work and the quote rest on three replies — what fluid, which amount, and if it's run — so our technicians ask. During the phone call itself, you hear the quote — ahead of anything else. Next: a drain, then a thorough flush of the entire system. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither washes away unaided. That is why it matters more. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. We do not go until it has been fired up and is running smoothly. If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. Paying is on the day, not upfront, and you receive the paperwork an insurer wants: an engineer's report and a VAT invoice. Wrong-fuel cover is included in many insurance policies — so use the wait to check yours. ## About Morchard Bishop Morchard Bishop is a village in Devon, situated on the riverside at an elevation of 165 metres, with detached housing being the predominant type of accommodation.
