Find Your Situation What to do about AdBlue in a diesel tank depends on one thing more than any other: if the engine has been run since it went in. Anywhere your vehicle is — Llangwstenin, Penrhyn Bay — don't start an engine that hasn't run yet. Keep nothing on, ring 0333 366 0103, and count on a thorough flush plus a drain, done just where the vehicle sits around Penrhyn Bay. Where the motor has run, stop somewhere safe first, then switch the vehicle off. Step one stays the same, even if the work grows. Anywhere around Conwy it took place, one of the situations below matches yours. ## AdBlue in a diesel on a Penrhyn Bay forecourt The cap you opened was the wrong one — and you only spot it while you're stood at the pump, bottle or the nozzle in hand. It might be the Gulf, or perhaps the JET, or another forecourt in Penrhyn Bay. What it means: this is the best place to find out. The AdBlue is inside your tank and nowhere else. Nothing has pulled it in. Freeing the petrol pump is no reason to start it — and so do not get back in. Have the attendants to lend a hand rolling it into a bay, save the bottle, then ring us right there. Can't move the car by the pump? Explosion-proof equipment keeps a live forecourt safe, and so we can drain the vehicle in place. ## Penrhyn Bay, at home: AdBlue in the diesel tank Several days had gone by with the warning light on. Picked up a bottle, poured it in at home, recycled the empty — and at that point looked at the cap a second time, after the fact. Just off Llandudno Road is no less likely from anywhere. Meaning? As long as your car has not been driven since, it is second to the pump case. AdBlue doesn't mix with diesel; it sinks to the bottom of the tank and waits there. Overnight doesn't change that. Your move: the keys in the house, and so no one drives the vehicle off first thing. After that, phone. Our engineers drain it on your drive, whether that is in Penrhyn Bay or out in Penrhyn-side. Even at night, the pumps are quiet enough for a residential street. ## Set off with AdBlue in a diesel in Penrhyn Bay? You filled up, set off, and a mile or two later your motor began to run roughly, smoke, lose power or light up the dashboard. Somewhere along Glan-Y-Mor Road or else on the road to St Asaph — under 15 miles away. Meaning? The pump has sucked the AdBlue up. Distance decides how deep it goes: filter and pipework to begin with, then the injection pump and every injector. It travels deeper with each mile driven and every restart. Stop safely — that is the next job — then turn everything off. Penrhyn Bay lies under 50 miles from the Moreton Spur; on it, come off at the next junction rather than pushing on to the services. It will not have cleared, and so there is no point starting it again to find out. Tell us hear the distance driven when you ring. ## A hire or company car with AdBlue in the wrong tank? A week ago, the car was unknown to you. Unbeknown to you, the AdBlue and diesel fillers sit side by side here — not like your own vehicle, which has none or keeps it in another spot. Across Conwy, nobody is safe from it. The upshot: just as above, divided by if it ran, but with one added step. Any work on the car often needs the owner's go-ahead under rental or company agreements. Next: ring the hire company or the fleet manager first, then us — sorting it before we arrive is faster. Waiting for a reply at the car park at Llandudno, or beside Jen Art? Leave the car off throughout. ## Penrhyn Bay: unsure whether it was AdBlue in the diesel tank? "I think so" is sometimes as honest as it gets. Too light, the bottle; a hint of ammonia round your filler; no clear recollection of which cap. Look familiar? A hurried top-up by the gates of the local primary school, or a visit to a friend in Rhos-on-Sea: both fits. What it means: a little spilled around your filler does no damage to your engine. AdBlue inside your diesel tank does. Firing up the car will not tell you which, and if there is AdBlue in that tank it would pull it in. What to do: treat it as if it got in. Do not start it. Call us and describe what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run. ## The common ground in every Penrhyn Bay AdBlue drain Each situation has the same start to the job. Anywhere the car is — Craft Beer Cave's car park, a road by St David's, a driveway, a forecourt — the van arrives and asks for the fluid, the quantity, and whether your engine has been run. Those answers settle the work, and you get our price by phone, before anyone sets off. Then your tank is emptied and your system rinsed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't rinse out on its own. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. If your engine has not run, most jobs take about half an hour once we're there. We start the car last. Before we head off, it's tested to make sure it runs properly on fresh diesel. When it is noticed soon, the car very rarely has lasting damage, and the entire job takes place where it is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance while we're en route: cover for misfuelling comes included in plenty of policies. ## About Penrhyn Bay and where it is Penrhyn Bay is a coastal village in Conwy, situated on the north Wales coast at an elevation of 24 metres, with detached housing being the predominant type of accommodation.
