Caught before your motor runs, it is normally a drain and a thorough flush, done where the vehicle is in Stamford Hill. The remainder of this page explains why it takes place and how to make sure it doesn't — handy if you are reading ahead of time. ## AdBlue in a diesel car, and its separate tank No single liquid but two: that is what plenty of newer diesels around Stamford Hill and Craven Walk carry, with diesel for your motor. Its own tank holds it, and from there it goes to the exhaust, where a spray cleans the fumes. Different tanks, separate fillers. Under one flap, next to each other: that is the layout on a lot of cars. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. Diesel goes in at every forecourt visit, week in, week out. Rarely filled, AdBlue normally comes from a bottle, tipped by someone who must stop and think which cap it needs. The error lives in that gap. ## Stamford Hill: how AdBlue in the diesel tank happens It's rarely carelessness. Three things tend to line up. On a drive off Wilderton Road before work, or in the car park at The Bird Cage heading home: that's where the hurried top-up happens. Why the rush? As AdBlue gets low the car warns you, and once it's empty, limp mode follows. Then the vehicle is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one. A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. So the pour, once started, carries on. The same few seconds decide it, in the middle of Stamford Hill or out in South Tottenham. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a drive in West Hackney or a forecourt around Stamford Hill, check these. They take a few seconds. - Where it sits can mislead; the cap does not. AdBlue caps are often blue or carry the word "AdBlue" — diesel ones normally do not. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - Lift the filler flap and check for a label — plenty of motors show which goes in which filler just there. - Can't find it beside your diesel filler? Then check below the bonnet or inside the boot — the owner's manual will say which. - The previous driver will know. Ask when you pick up a hire car or fleet car — at the nearest station's car park, say — not when the warning comes on. ## Topping up AdBlue without it reaching your diesel tank Anywhere across Greater London the light comes on, here is a routine for the day. - Switch off once parked — level ground, motor off, and not in a rush by Colberg Place on the verge. - Find the AdBlue filler, check the cap, and say the word "AdBlue" aloud as unscrewing it. It sounds silly. It works. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Finish once that tank is topped up or the bottle is empty; until then, tip gently through its built-in spout. - Close the cap, then check once more — confirm your diesel cap remained shut the whole time. After that, start the car. Discover at the second or third step that the bottle went into the wrong filler? That's where you stop. Leave out stage five entirely. ## Already put AdBlue in the diesel tank in Stamford Hill? What follows is a short order of things, beginning with no starting the motor. On many diesels the ignition alone runs the fuel pump, and so don't switch the car on. Thinning it with extra diesel fails, because AdBlue settles to the base rather than blending — and that is where the fuel is sucked from. At a forecourt — Esso, Shell or any other — the attendants will usually help roll the vehicle clear, when you ask. If you're on your own drive around Stamford Hill, leave it where it sits. If the engine has already run, stop as soon as it is safe and switch off. Leave the M11 — under 5 miles out of Stamford Hill — at the next exit. About how far did it go? Hopping across Stamford Hill is less a job than a trip of under 5 miles to London, so tell us. ## When our technicians turn up around Stamford Hill, what occurs? Our van reaches the car wherever it has come to rest — your own driveway, near Peter Collins Memorial Community Hall, or outside Lubavitch Girls Primary School. What liquid got in, the quantity, and whether it ran: our technicians ask because those replies decide both work and quote. You get that quote on the phone, before anyone sets off. Then the tank is drained and your system purged thoroughly. 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. The filter flushed or, where needed, replaced; clean diesel in; and then a check of the vehicle. We do not go until it has been started and is running correctly. If your engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. No money in advance; you settle up on the day. At the end, the VAT invoice and a report from the engineer go to you for your insurer. Misfuelling cover is part of plenty of insurance policies — so make use of the wait to look at yours. ## About Stamford Hill itself Stamford Hill is a suburban area in north London, situated near several large lakes and reservoirs, including the Stoke Newington Reservoirs, at an elevation of around 29 metres.
