AdBlue already in the diesel tank? In that case put this page down a moment, leave the ignition and motor off, then call 0333 366 0103. Caught before the motor runs, it's usually a drain and a thorough flush, done where the vehicle is in Radbrook. If you're reading before it has happened, the remainder of this page is about why it happens and how to make sure it doesn't. ## Why does AdBlue in a diesel car need its own filler? Diesel goes to your engine — yet many modern diesels seen about Radbrook and Meole Brace hold a second fluid too. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. There is a filler for every tank. Under one flap, next to each other: that's the arrangement on many motors. Elsewhere, AdBlue's filler sits under the bonnet or in the boot instead. Topping up the diesel side at the petrol pump goes on constantly. Rarely filled, AdBlue usually comes out of a bottle, poured by someone who must stop and think what cap to use. Mistakes happen in that gap between them. ## How does AdBlue in the diesel tank occur around Radbrook? Seldom is it carelessness: normally three things line up. On a driveway off Bank Farm Road before work, or in the car park at The Inn On The Green on the way home: that's where the hurried top-up happens. What is the reason for the rush? As AdBlue runs low the vehicle tells you, and if it's empty, limp mode follows. Then the vehicle is new. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and your hand gets to for the cap it would have used on the old one. Lastly, the bottle fits: a diesel filler or AdBlue one, it slides in as readily, and once the pour starts, no part halts it. Whether it takes place in Porthill or the middle of Radbrook, it is the same few seconds. ## Telling the AdBlue filler from the diesel filler Whether a Radbrook forecourt or a drive over in Kingsland, take a few seconds on these before any is poured in. - Where it sits can mislead; the cap does not. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel ones usually don't. - Plenty of cars fit AdBlue the smaller filler of the two. - A label inside your fuel flap often says which fuel goes where, on plenty of cars. Check for it. - The handbook. If the filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which. - The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Shrewsbury, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching your diesel tank Anywhere around Shropshire the light comes on, this is a routine for that day. - Pull in on level, motor off, with time to spare — never hurried on the side of St. Andrews Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - The two under a single flap? Then make sure the cap on the diesel side is still closed ahead of lifting the bottle. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before you start the car, close the cap and look again that the diesel cap was never came off. Spot at stage two or three that it's already gone into your diesel side? Then stop just there. Never go on to step five. ## AdBlue in your diesel tank already, around Radbrook? The short order of things, beginning with no starting your motor. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is pulled from. Ask the staff to help push the vehicle away from the pump if you're at a forecourt — the Esso, the Local or somewhere else. Your own drive in Radbrook is where it should stay.

Anywhere your car has stopped, be it outside Radbrook Primary School, beside Radbrook Community Centre or on your own drive, the van travels to it.

Next: a drain, then a full flush of the entire system. More than with petrol, it matters with AdBlue: the crystals form, certain metals are attacked, and nothing washes away on its own, however long it sits. A test is last: before that, clean diesel is added, and the fuel filter is flushed or replaced if necessary. Before leaving, our engineers fire it up and check that it's running correctly.
