Then put this page down for now, keep the ignition and motor off, and call 0333 366 0103. Caught before your engine runs, it's normally a drain and a thorough flush, done where the vehicle is around Tye Common. The remainder of this page covers why it occurs and how to ensure it does not — handy if you're reading ahead of time. ## Why does AdBlue in a diesel motor need its own filler? Diesel goes to your engine — but many current diesels seen around Tye Common and Haverings Grove carry a second liquid as well. Its own tank holds it, and from there it goes to your exhaust, and there a spray cleans the fumes. Every tank has one filler of its own. Some vehicles keep the AdBlue filler in the boot or under the bonnet; plenty of others have both together behind one flap. The diesel side is fuelled at the petrol pump all the time. Rarely filled, AdBlue usually goes in from a bottle, tipped by a driver who has to stop and think which cap it needs. The mistake lives in that gap. ## AdBlue in your diesel tank around Tye Common: how it takes place Carelessness seldom explains it. What does is three things lining up together. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a driveway off Tyelands before work, or in the car park outside The Red Lion on the way home. Then the car is unfamiliar. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one. Third, the bottle goes in: a diesel filler or AdBlue one, it goes in just as easily, and once the tip begins, nothing stops it. Billericay or the heart of Tye Common: it takes the same few seconds in both. ## Telling the AdBlue filler from the diesel filler Before you tip anything, whether on a driveway in Sunnymede or a forecourt in Tye Common, check these. They take a few seconds. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap usually isn't. Read it rather than going by where it sits. - Many cars fit AdBlue the smaller filler of the two. - A label inside the fuel flap frequently shows which fuel goes where, on plenty of motors. Check for it. - The handbook shows where it lives when the filler isn't next to your diesel cap: your boot, or under the bonnet. - Picking up a hire or company car, perhaps at the car park outside Billericay? Ask whoever drove the vehicle last before you set off, not once the light comes on. ## How to top up without AdBlue in your diesel tank A routine for the day the light comes on, wherever around Essex that is. - Not in a rush on the side of Tye Common Road, not on a slope, not with the engine running: park and switch off properly. - Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — once you have found your filler and read it. - The diesel cap stays on. When both sit under a flap, confirm it's closed before the bottle comes up. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Close the cap and check once more. Make sure your diesel cap was never opened. Only then start your car. Spot at step two or three that it has already gone into the diesel side? So stop right there. Never go on to step five. ## AdBlue in your diesel tank already, in Tye Common? What follows is a short order of things, beginning with not starting the motor. Do not switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is sucked from — so do not top up with diesel to dilute it. If you're on a forecourt, whether it is the BP or the another forecourt nearby, ask the staff to help push your car away from the pump. At home in Tye Common? Then your car remains where it is. Stop as soon as it is safe and switch off, if your motor has already run. On the M25, under 10 miles from Tye Common, that means the next exit.

Outside Quilters Junior School, near Billericay Town Football Club or on your own driveway: wherever the vehicle has stopped, our engineers come to it. Our technicians ask what went in, about how much, and if it has run, because the answers settle this work and the price. Nobody heads out until you have had the price by phone. Emptying the tank comes next, then a thorough flush of the system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. After your filter has been cleaned — or replaced, if needed — clean diesel goes in, and then your car is tested. The engine is fired up next and tested to confirm it runs properly, all before our technicians go. If your motor has not run, most jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. The insurer will ask for an engineer's report and your VAT invoice, and both are yours once this job is done. Payment is on the day, with no money upfront. Before we get there, take a look at your policy; plenty carry cover for misfuelling. ## About Tye Common Tye Common is a suburban area in Essex, situated near the River Thames and characterised by semi-detached housing.
