Find Your Situation What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the engine has run since it was put in. Not run so far? Then leave the car that way, wherever the vehicle is — Millbrook or Crumlin. Usually this means emptying and thoroughly flushing it right there in Millbrook — so keep your key and motor off and ring 0333 366 0103. Where your engine has been run, stop somewhere safe straight away, then switch the car off. It is a larger job, yet stage one doesn't change. Find the situation below that matches yours, wherever in Caerphilly it happened. ## Millbrook forecourt: AdBlue in a diesel at the pump Imagine it: standing by the petrol pump, gripping the bottle, you realise the filler you took off wasn't the correct one. Maybe you're at the Texaco, possibly at the another forecourt nearby, maybe somewhere else around Millbrook. The upshot: of all places to notice, this is the best. Just your tank holds AdBlue; no component beyond it has drawn it in. Do this: stay out of the driver's seat, however much the queue wants clearing. Ring us from the forecourt after your vehicle is in a bay — the attendants will help push it — and save the receipt. Stuck beside the petrol pump? Our explosion-proof kit keeps a busy forecourt sensible, so it can be drained where it is. ## At home around Millbrook with AdBlue in the diesel tank For days the dashboard had been nagging you. Picked up a container, tipped it in at home, recycled the empty — and at that point checked the cap again, after the fact. It takes place on drives just off Woodview Terrace as regularly as anywhere. In short: if the car has not been driven since, it is nearly as good as finding out at the pump. At the floor of the tank sits exactly where AdBlue stays, because it will not blend with diesel — and a night going by changes no difference. Put your keys indoors overnight — otherwise someone might drive it away first thing — and call us. Rhiw or Millbrook: wherever your drive sits, that's where it gets cleared. Even at night, the pumps are quiet enough for a driveway. ## AdBlue in a diesel and already driving in Millbrook? You filled up, set off, and a mile or two later your engine began to run unevenly, smoke, lose power or light up the dashboard. Kendon Road, say, or the route towards Newport — a trip of under 10 miles. What it means: the system has drawn the AdBlue in. It has been through the fuel filter and the lines and, the further you went, into your high-pressure pump and your injectors. It travels deeper with every mile driven and every restart. Your move: pull up anywhere sensible, then switch the engine off. Service stations farther along are too far: on the M4, under 10 miles out of Millbrook, use the next junction. Starting it again to test achieves nothing — AdBlue doesn't clear on its own. Phone, saying how far your vehicle went. ## Hire, lease or company car with AdBlue in the wrong tank You have just had this car a week. The AdBlue filler sits right beside the diesel one, which you did not know, because your own car either has no AdBlue or keeps it somewhere else. It can happen to anyone, anywhere across Caerphilly. In short: one extra step on top of the situations above, which turn on whether it has run. Plenty of hire and company agreements want the owner to approve work on the car. Your move: hire firm or fleet manager first, us next, since sorting it early saves time. Stranded by Horeb Chapel or outside Newbridge till the firm replies, the vehicle stays switched off throughout. ## Unsure about AdBlue in your diesel tank around Millbrook? Now and then, "I think so" is all anyone can truthfully say. The bottle is lighter than it should be, there is a faint smell of ammonia round the filler, and you can't remember which cap you took off. A rushed top-up by the gates of the local primary school, or a call to a friend in Pentref-y-groes: either fit. Meaning? Spills outside the filler don't reach the engine at all. If it is inside your diesel tank, though, that changes. Starting the vehicle will not tell you which, and if there is AdBlue in that tank it would pull it in. Do this: act as though it did, and don't start your motor. Phone and give what you saw: we would rather confirm a clean tank than empty one after your engine has run. ## What each AdBlue drain around Millbrook has in common Each case gets the same start to the job. Wherever the car stands — The New Forge's car park, a road by Swffryd Community Centre, a driveway, a filling station — our van arrives and we ask about the liquid, the quantity, and whether your motor has been run. Those answers determine the work, and you hear the price by phone, before anyone heads out. A thorough flush comes after the drain. With petrol it's routine; with AdBlue it's crucial, because deposits form and some metals corrode, and none of it rinses away unaided. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Where your engine hasn't run, expect about half an hour on site, in most cases. Firing it up comes last. Our technicians check it runs properly on fresh diesel before leaving. Our engineers do the whole job where the vehicle is, and lasting damage is very rare when it has been spotted soon. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Dig out your insurance before we arrive: cover for misfuelling is built into plenty of policies. ## About Millbrook and where it is Millbrook is a suburban area in Caerphilly, situated on the riverside with a mix of terraced housing.
