Find Your Situation Has the motor run since the AdBlue went in? That one point settles almost everything else from here. If it has not, keep it that way, whether your car is in Waen itself or out in Llansanffraid-ym-Mechain. Leave the engine and your ignition off then ring 0333 366 0103; it's generally a drain and a thorough flush, done where the car is around Waen. If it has run, stop as soon as it is safe then switch off. It is a larger job, though step one doesn't change. Find the situation below that matches yours, wherever in Powys it happened. ## On a Waen forecourt with AdBlue in a diesel The cap you opened was the wrong one — and you just notice it as you're standing at the petrol pump, bottle or the nozzle in your hand. Be it Esso, Texaco or anywhere else around Waen, the situation is identical. The upshot: of all places to find out, this is the best. Just the tank holds AdBlue; no part beyond it has taken it in. Do this: stay out of the car, however much the pump needs clearing. A few things: a push into a bay with the attendants assisting, the receipt saved, and a ring to us from where you stand. If it can't be moved, it can be cleared at the pump: the equipment is explosion-proof and fine on a working forecourt. ## AdBlue in the diesel tank at home around Waen The warning light had been on for days. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look once more at the cap. Homes just off Waen Meadows are caught out as much as anywhere else. The upshot: zero miles since leaves it nearly as good to spotting it at the petrol pump. As it is unable to mix, AdBlue settles to the base in the tank and stays. One night standing alters none of that. Put the keys indoors tonight — or someone may drive it off first thing — then call us. Tre-derwen or Waen: wherever your drive sits, that's where it gets drained. Night-time drains outside a house are no problem: the pumps are low-noise. ## AdBlue in a diesel and already driving around Waen? Filled up, drove away, and soon the engine was turning roughly, blowing smoke, losing power, or lighting up the dash. Maybe driving to Wrexham, under 25 miles away, or simply along B4393. What it means: the system has drawn the AdBlue in. The high-pressure pump and each injector get it too on a bigger run, after the fuel filter and lines have had it. More driving, more restarts: deeper it goes. What to do: pull over where it is safe then switch off. Waen sits under 50 miles from the M54; on it, pull off at the next junction instead of pressing on to the services. Don't restart it to see if it has cleared; it will not have. Roughly how far did it go? Tell us as you call. ## AdBlue in the wrong tank: hire, lease and company cars It's a car you have had for a week. On your own vehicle, AdBlue is absent or somewhere else. On this one, its cap is right by your diesel inlet — a surprise to you. Across Powys, no one is safe from it. The upshot: exactly as above, split by if it ran, only with an added stage. The owner frequently has to approve the work, under many hire and company agreements. Next: ring the rental company or your fleet manager first, then us — settling it before we arrive is faster. If you're stranded in the car park at Welshpool, or by St Ffraid's, whilst you wait for an answer, leave the vehicle off. ## Waen: unsure if it was AdBlue in the diesel tank? Now and then, "I think so" is all you can honestly say. The bottle is lighter than it should be, there is a faint smell of ammonia around the filler, and you cannot remember which cap you took off. The gates of Bryn Offa CofE Primary School in a hurry, say, or a friend's drive over in Deuddwr. What it means: a little spilled round your filler does no harm to your motor. AdBlue inside your diesel tank does. If there is AdBlue in that tank, firing up the car will draw it in, and it would not tell you which either. Take it that it was put in, and don't turn the engine. Tell us what you noticed on the phone. A clean tank checked counts as a better result than a run one emptied. ## Every AdBlue drain in Waen shares these steps Whatever the situation, a single start is used. Our engineers come to the car, whether it is on a forecourt, a driveway, the car park outside The Sun or a side street close to St Michael's, and ask three things: what got in, about how much, and if your motor has been run. Over the phone, before dispatch, you hear the quote, and those replies decide the job too. AdBlue crystallises and eats at certain metals in fuel systems, so it does not rinse out unaided; that is why a full flush, after this drain, counts much more here than with petrol. Then is the fuel filter — cleaned, or swapped where needed — then clean diesel, and a test of the vehicle. The majority of unrun vehicles are a half-hour visit after the moment we arrive. We fire it up at the end. We confirm it runs correctly on new diesel before we go. Permanent damage is very rare if it's caught soon, and the whole job is done where the car is. Payment is on the day, never upfront. For the insurer, you get a VAT invoice plus a report from the engineer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## About Waen itself Waen is a small hamlet situated on the riverside in Powys, Wales, with a low elevation of 79 metres.

The van drains it in place.

Already run: stop, switch off and ring. Either way, Petrol in Diesel takes it from there in Waen and anywhere in Powys on 0333 366 0103.
