Stop reading for a moment when the diesel tank already holds AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain plus a thorough flush, done right where your vehicle sits in Stanbrook, is usually all it takes if caught before your engine runs. Reading in advance? In that case what follows explains how it happens and how to stop it ever happening. ## AdBlue in a diesel motor: two tanks, two fillers Many modern diesels around Brayswick, as well as Stanbrook, carry on two fluids; your engine gets only the diesel. The exhaust, not the motor, is where AdBlue goes: sprayed into the gas to fresh it, from a separate tank. Every tank comes with one filler of its own. Under one flap, next to each other: that's the layout on many cars. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead. At the pump, the diesel side gets filled constantly. Seldom topped up, AdBlue usually goes in out of a bottle, poured by someone who must stop and think what cap to use. The mistake grows in that gap between the two. ## AdBlue in your diesel tank in Stanbrook: how it occurs Carelessness rarely causes it. Instead is three things coming up at once. Hurry comes from the warning. Your car tells you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done in a rush, before work on a drive off Frog Lane, or heading home in the car park at The Blue Bell. The old car's cap is where the hand reaches — but a hire car, a new motor or a company car puts the fillers somewhere else. That is a second factor: a new motor. Lastly, the spout fits: diesel filler or AdBlue filler, it goes in just as readily, and after the pour starts, nothing halts it. Callow End or the heart of Stanbrook: it is the same few seconds either way. ## Which filler is for AdBlue, and which for diesel? Before you tip anything, whether on a drive in Deblins Green or a forecourt around Stanbrook, check these. They take a couple of seconds. - Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not its position. - On many vehicles, the size tells: AdBlue gets the smaller filler neck. - Open the filler flap and look for a label — many vehicles show which belongs in which filler just there. - Cannot find it beside the diesel inlet? Then look below the bonnet or in your boot — the handbook will say which. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Worcester Foregate Street, ask before you leave, not when the light comes on. ## How to top up without AdBlue in the diesel tank Wherever across Worcestershire the light comes on, this is a routine for that day. - Not in a rush on the side of Abbey Close, not on a slope, not with the engine running: park and switch off first. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, yes, yet it works. - The two under one flap? Then confirm the cap on the diesel filler is still closed before raising the bottle. - Slowly does it, through the bottle's own spout, till it is full or the bottle runs out. - Only after that, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened. Find during the second or third stage that AdBlue went into the diesel tank? That is where you stop. Skip step five altogether. ## Put AdBlue in your diesel tank in Stanbrook already? Then the order of things is short. Do not start your motor. On plenty of diesels your ignition alone runs the fuel pump, so do not switch it on. Topping up with diesel won't dilute it: rather than mixing, AdBlue sinks to the bottom of the tank, right where the fuel is drawn from. The staff at JET, Esso or any forecourt will usually help to push your car away when asked. Leave it where it is if you're on your own drive in Stanbrook. When your engine has been run by now, pull over safely then switch the car off. Stanbrook lies under 3 miles from the M5; on it, take the next junction. Tell us roughly how far it went: a run towards Worcester, under 5 miles away, is a bigger job than a short hop across Stanbrook. ## Stanbrook: what takes place when we arrive Wherever your car came to rest, whether by Callow End CofE Primary School, beside Callow End Village Hall or at home, our van travels to it. Our engineers ask what was put in, roughly how much, and if it's run, since those answers determine this work and our quote. No one heads out until you've had our price over the phone. Then the tank is cleared and your system flushed thoroughly. Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither clears away unaided. Hence it matters more. Once your filter is cleaned — or renewed, where needed — clean diesel is added, and finally your car gets tested. Before we go, our technicians fire it up and confirm that it is running correctly. Unrun cars usually mean a half-hour job after arrival. The equipment is fine on a busy forecourt, and hushed enough for a residential street after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is included in many insurance policies — so make use of the wait to check yours. ## About Stanbrook and where it is Stanbrook is a suburban area located near Worcester in Worcestershire, England, with a mix of detached housing and local amenities.
