Keep the motor and ignition off then phone 0333 366 0103 first — the rest can wait when AdBlue is already in the diesel tank. Around Woodmer End, finding it before your engine runs usually leaves a drain and a thorough flush where it stands. If you are reading before it has happened, the rest of this page is about why it takes place and how to make sure it doesn't. ## AdBlue in a diesel motor: two tanks, two fillers No single liquid but two: that's how many modern diesels near Woodmer End and Shillington run, with diesel for your engine. Kept in a tank of its own, AdBlue is fed into the exhaust gas and cleans it. Separate tanks, different fillers. Under one flap, side by side: that is the layout on a lot of motors. Elsewhere, AdBlue's filler is under the bonnet or in your boot instead. Topping up the diesel side at the pump happens all the time. Seldom filled, AdBlue usually goes in from a bottle, tipped by a driver who has to stop and think what cap it needs. The mistake lives in that gap. ## How AdBlue in the diesel tank occurs around Woodmer End Rarely is it carelessness: normally three things coincide. The warning comes first. As AdBlue runs low your car 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 Bedford Close before work, or in the car park at The Crown on the way home. Then your car is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand hits for the cap it would have used on the old one. A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. So the pour, after started, keeps on. Hillfoot End or the heart of Woodmer End: it is the same few seconds in both. ## The AdBlue filler and the diesel filler: telling them apart A few seconds is all the checks take — so check them before you tip anything, on a driveway in Lower Gravenhurst or a forecourt around Woodmer End. - Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not where it sits. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook. If your filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Arlesey, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank On the day the light appears — anywhere it is around Bedfordshire — a simple routine to follow. - Switch off once parked — flat ground, engine off, and not in a rush beside Bury Road on the verge. - Find the AdBlue filler, read the cap, and say the word "AdBlue" out loud as unscrewing it. It seems daft. It does the trick. - The diesel cap stays on. When both sit under a flap, confirm it's closed before the bottle comes up. - Gently does it, through the bottle's own spout, until it's full or the bottle runs out. - Only after that, start your car: close the cap, check once more, and make sure your diesel cap was never opened. Find during the second or third stage that AdBlue went in the wrong filler? That's where you stop. Stage five stays out. ## Already put AdBlue in your diesel tank in Woodmer End? Then the order of things is short. Don't start your motor. Don't 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 that tank, where your fuel is sucked from. Ask the staff to help push the car away from the petrol pump if you're on a forecourt — the F C Dawes & Son, the Power or anywhere else. If you are on your own drive around Woodmer End, leave the vehicle where it sits. If the engine has already run, stop as soon as it is safe and switch off. Woodmer End lies under 10 miles from the Toddington Services Southbound; on it, use the next exit. Mileage matters — a short hop across Woodmer End is a smaller job than driving under 25 miles towards Milton Keynes — so say roughly how far it went. ## What takes place when our technicians turn up in Woodmer End Outside Shillington Lower School, near Shillington Village Hall or on your own drive: wherever your car has stopped, our engineers come to it. Both the work and the quote rest on three answers — what fluid, which quantity, and whether it has run — so we ask. On the call itself, you hear the quote — before dispatch. Emptying that tank comes next, then a full flush of your system. Unlike petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither washes away by itself. Hence it matters more. Testing comes at the end: before that, fresh diesel is added, and the filter is cleaned or changed as needed. Before we leave, our engineers fire it up and check that it's running properly. If the motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. Your insurer usually wants the engineer's report and your VAT invoice, and you get both once this job is done. Payment comes on the day, with no money upfront. Before we get there, take a look at your insurance documents; many carry cover for misfuelling. ## About Woodmer End Woodmer End is a suburban area in Bedfordshire, situated near the River Great Ouse at an elevation of 51 metres.
