A drain plus a thorough flush, carried out right where your vehicle sits around Richings Park, is normally all it takes if found before your motor runs. Nothing happened yet? Further down, the rest of the page covers the reasons it occurs and the how to prevent it altogether. ## AdBlue in a diesel vehicle, and its separate tank Diesel goes to the engine — yet plenty of modern diesels seen round Richings Park and Love Green carry a second fluid as well. Its own tank keeps it, and from there it goes to the exhaust, and there spraying treats the fumes. Each tank has its own filler. Some motors put the AdBlue filler in the boot or under the bonnet; a lot more place both side by side behind one flap. Filling the diesel side at the petrol pump happens constantly. The AdBlue side is topped up far less regularly, normally from a bottle, and usually by somebody who has to stop and think where it goes. That gap is where the slip lives. ## Richings Park: how AdBlue in your diesel tank takes place Three things tend to line up, and carelessness is rarely one of them. Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up happens in a rush, before work on a driveway off Syke Ings, or on the way home in the car park outside The Tower Arms. Then, your hand reaches for the cap it knew on the old car — because a hire car, a new car or a company car puts the fillers where your last one did not. Lastly, the bottle goes in: diesel filler or AdBlue filler, it slides in just as easily, and once the tip starts, no part halts it. Thorney or the middle of Richings Park: it takes the same few seconds either way. ## How to tell the AdBlue filler from the diesel one Look at these first, at a forecourt in Richings Park or a driveway out in Little Britain. Seconds, that's all. - Colour and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position. - On plenty of cars, the size gives it away: AdBlue has the smaller filler neck. - Look inside the fuel flap: many vehicles have a label there showing which fuel goes where. - Can't see it beside the diesel filler? In that case look beneath the bonnet or in your boot — the handbook says which. - Whoever had it before will know. Check when you pick up a rental or company car — at Iver's car park, perhaps — not when the light comes on. ## How to top up without AdBlue in the diesel tank Anywhere across Buckinghamshire the light comes on, this is a routine for the day. - Stop somewhere level, engine off, with time in hand — never hurried on the side of Bathurst Close. - Find the AdBlue filler, check the cap, and speak the word "AdBlue" out loud while you unscrew it. It sounds silly. It works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the vehicle on. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Only then, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened. Find during the second or third stage that AdBlue went in the diesel tank? That's where you stop. Step five is off limits. ## AdBlue in your diesel tank already, in Richings Park? Brief list, then. First: the motor remains unstarted. Keep the ignition off as well, since on many diesels it alone runs the pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from. If you are on a forecourt, whether it's the Esso or the Shell, ask the staff to help roll the car clear of the pump. At home in Richings Park? Then the vehicle stays where it is. If your engine has already run, stop as soon as it is safe and switch off. The next exit means the place to come off if you're on the M25, under a mile from Richings Park. Tell us about how far it went: a run towards Westminster, under 25 miles away, is a bigger job than a short hop across Richings Park. ## Our arrival in Richings Park, and what takes place next Our engineers come to the vehicle wherever it has stopped, whether that's outside Iver Village Infant Academy, close to Richings Sports Park or on your own drive. Our engineers ask what went in, about how much, and if it's run, since the answers decide this work and our quote. That price is given over the phone, ahead of any van leaving. After that: draining, then a thorough flush of the whole system. Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and none of that washes away by itself. That is why it matters more. Once the filter has been cleaned — or replaced, if needed — clean diesel goes in, and then the vehicle is tested. Your engine is started next and checked to make sure it runs correctly, all before our technicians go. Unstarted vehicles mostly mean a half-hour job after arrival. The kit is fine on a busy forecourt, and quiet enough for a driveway late at night. Your insurer usually wants the engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. It's worth checking your insurance as the van travels to you: misfuelling cover is included with many policies. ## About Richings Park itself Richings Park is a village situated on the riverside in Buckinghamshire, with an elevation of 34 metres above sea level.
