A drain plus a full flush, done right where the car stands in Salhouse, is normally what it needs if caught before the motor runs. The remainder of this page covers why it takes place and how to ensure it doesn't — useful if you're reading ahead of time. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of modern diesels on the roads around Salhouse and Woodbastwick carry two liquids, not one. Diesel goes to the motor. Its own tank keeps it, and from there it goes to your exhaust, where spraying treats the fumes. 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. Filling your diesel side at the pump goes on all the time. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and far less commonly. That gap is where the mistake lives. ## How does AdBlue in your diesel tank happen around Salhouse? Three things tend to come together, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the car goes into limp mode. So the top-up is done in a hurry: on a driveway off Norwich Road before work, or in the car park outside The Stag on the way home. Then your car is strange. A hire car, a new car or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have used on the old one. A spout-topped bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the tip, once started, keeps on. The same few seconds decide it, in the middle of Salhouse or out in Primrose Corner. ## The AdBlue filler and your diesel filler: telling them apart Before you pour anything, whether on a driveway in Rackheath or a forecourt in Salhouse, check these. They take a few seconds. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it rather than going by position. - Plenty of vehicles give AdBlue the smaller neck of the two. - Open the flap and look for a label — plenty of vehicles mark which goes in each inlet right there. - In the boot or under the bonnet: that is where the filler is if it's not by your diesel cap, and the handbook says which. - Collecting a hire or company car, perhaps at the car park outside the nearest station? Check with whoever drove the car last before you set off, rather than once the light comes on. ## AdBlue top-ups that never reach the diesel tank When the light goes on, wherever in Norfolk, follow this routine. - Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Mill Road. - Locate the AdBlue filler, check the cap, and say the name "AdBlue" aloud while you unscrew it. It sounds silly. It does the trick. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the car. If at step two or three you find you have already poured into your diesel side, stop there. Stage five stays off limits. ## Put AdBlue in the diesel tank around Salhouse already? Do not start the engine: that's where the short order of things begins. The fuel pump starts on plenty of diesels the moment your ignition is switched on — so keep it off. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is sucked from. If you are at a forecourt, whether it is the JET or the Shell, ask the attendants to help push your car clear of the pump. Leave it where it is if you're on your own drive around Salhouse. Stop as soon as it is safe then switch off, if your motor has already run. Come off the M11 — over 50 miles out of Salhouse — at the first exit. Tell us roughly how far it went: a run towards Norwich, under 10 miles away, is a bigger job than a short hop across Salhouse. ## Our arrival around Salhouse, and what occurs next Our engineers come to the car wherever it has stopped, whether that is outside Salhouse CofE Primary School, close to Salhouse Village Sign or on your own drive. Those replies decide this work and the price, and so we ask what went in, roughly how much, and if it has run. No one sets off until you have heard the quote by phone. Next: a drain, then a thorough flush of the entire system. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither washes out by itself. Hence it matters more. Once the filter has been flushed — or renewed, if required — fresh diesel goes in, and then the vehicle gets tested. The engine is started next and tested to confirm it runs correctly, all before we leave. Unrun vehicles mostly mean a half-hour visit from the moment we arrive. The kit is safe on a live filling station, and quiet enough for a residential street after dark. Payment is on the day, not upfront, and you receive the paperwork an insurer asks for: an engineer's report and a VAT invoice. Misfuelling cover is included in plenty of insurance policies — so use the wait to look at yours. ## About Salhouse and where it is Salhouse is a rural village in Norfolk, situated approximately 5.9 miles north of Norwich and 103.8 miles northeast of London.
