One fact matters above all when AdBlue is in a diesel tank, and that is if the motor has run since. If it hasn't, keep it that way, whether the vehicle is around Whitley itself or out in Whiteknights. Leave the engine and your ignition off and phone 0333 366 0103; it's generally a drain and a thorough flush, done where the vehicle is around Whitley. When your engine has been run, pull in somewhere safe straight away, then turn the car off. The job is bigger, yet the first stage is the same. Below: the cases our technicians see, anywhere in Berkshire. Pick the one that fits. ## On a Whitley forecourt with AdBlue in a diesel The cap you unscrewed was the wrong one — and you only notice it while you are standing at the petrol pump, bottle or the nozzle in hand. Whether Morrisons, Shell or anywhere else around Whitley, the situation is identical. The point: of every spot to notice, the forecourt is the best. Nothing has drawn it through, and so the AdBlue stays just inside your tank. What to do: don't get back in and fire it up to clear the petrol pump. Ask the staff to help you roll the vehicle into a parking space, keep the receipt or the bottle, then call us from the forecourt. Can't move the car by the pump? Our explosion-proof kit makes a live forecourt safe, and so it can be drained in place. ## AdBlue in the diesel tank on a Whitley drive? The warning light had been on for days. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look a second time at the cap. Right off Honiton Road is no different from anywhere. What it means: if you haven't driven since, this is nearly as good as the forecourt. At the floor of that tank is where AdBlue waits, since it will not blend with diesel — and a night going by changes nothing of the difference. Put the keys indoors tonight — otherwise someone might take it off first thing — and call us. Whitley Wood or Whitley: whichever your driveway is, that is where it gets cleared. Late-night drains outside a house are no problem: the pumps are low-noise. ## Whitley: drove off with AdBlue in a diesel? Topped up, pulled away, and before long your motor was turning unevenly, blowing smoke, losing power, or lighting up your dash. Anywhere along Northumberland Avenue or else on the road towards Oxford — under 50 miles away. The upshot: your system has pulled AdBlue through already. The injection pump and every injector get it as well on a bigger run, after the fuel filter and pipework have it. Each restart, like every mile, carries it on. Your move: pull up somewhere safe, then turn your engine off. On the M4, under 3 miles from Whitley, that means the next exit, not the services further on. It won't have cleared, so there is no sense restarting to check. Call, saying how far your vehicle was driven. ## AdBlue in the wrong tank: hire, lease and company motors Seven days back, the car was new to you. Your own vehicle either does without AdBlue or keeps it elsewhere, so no one warned you the AdBlue inlet was just next to your diesel. Anyone, wherever across Berkshire, could do it. Meaning? Whatever case above applies too — run or unrun — and one further stage. Work on your vehicle often requires the owner's go-ahead under hire or fleet terms. Your move: rental firm or fleet manager to begin with, us second, because sorting it early saves time. If you're stuck in the car park at Reading Green Park, or by South Reading Community Hub, whilst you wait for an answer, leave the vehicle off. ## Whitley: unsure if it was AdBlue in your diesel tank? Truthfully, the only answer may be that you think so. What cap came off, you cannot say; but the bottle weighs lighter than it ought to, and a whiff of ammonia lingers by the filler. A hurried stop by the gates of Whitley Park Primary and Nursery School, or a visit to a friend in Coley: both fit. Meaning? Spills around the filler never reach your engine at all. In your diesel tank, however, AdBlue harms it. If there is AdBlue in that tank, firing up the car will pull it in, and it would not tell you which either. Next: act as though it got in, and keep the motor off. Phone and give the details: we'd rather find a tank free of AdBlue than drain one after your motor has run. ## Whitley: what every AdBlue drain has in common Whichever situation you are in, this job starts the same way. Wherever the vehicle stands — The Victoria Cross's car park, a road beside The Well Church, a drive, a filling station — the van gets there and we ask about the fluid, the quantity, plus if your engine has been run. Those replies determine this work, and you get the price on the phone, before anyone sets off. Draining your tank comes next, then a careful flush — more important with urea than with petrol, since crystals and corrosion won't clear on their own, no matter how long it sits. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Not started? Then about half an hour once we are there is most jobs. The last step is firing it up. Before our engineers leave, it is tested to make sure it runs properly on fresh diesel. The whole job is done where the car is, and if it is spotted quickly, long-term damage is very unusual. Payment comes on the day, never upfront. For the insurer, there is a VAT invoice plus a report from the engineer. Check your insurance while we arrive: misfuelling cover is included in plenty of policies. ## About Whitley and where it is Whitley is a suburban area in Berkshire, situated inland at an elevation of 52 metres, and is located approximately 36 miles from London.
