--- title: AdBlue in a Diesel Tank Giants Grave? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/giants-grave-neath-port-talbot/ location: Giants Grave county: Neath Port Talbot latitude: 51.638180 longitude: -3.827990 service: AdBlue in a Diesel Tank updated: 2026-10-10 --- # AdBlue in the Diesel Tank in Giants Grave, and What to Do Next All of that hinges on one detail: whether your motor has been run since the AdBlue was added — far more than anything else. Out in Cwrt Sart or here around Giants Grave, an unstarted engine must remain that way. Leave the engine and your ignition off then ring 0333 366 0103; it's generally a drain and a thorough flush, done where the vehicle is around Giants Grave. Where your motor has been run, pull in somewhere safe straight away, then switch it off. It is a bigger job, yet step one doesn't change. Anywhere across Neath Port Talbot it took place, one of the situations below fits yours. ## AdBlue in a diesel on a Giants Grave forecourt Only at this point, nozzle still in your hand, it dawns on you that the cap you opened was the wrong one, there at the pump. Whether Texaco, Esso or anywhere else in Giants Grave, the situation is the same. The upshot: of all places to find out, this is the best. Only your tank holds AdBlue; no component past it has drawn any in. Do this: keep out of the driver's seat, however much the pump wants clearing. Ring us from the forecourt after your car sits in a space — the attendants will lend a hand to push it — then keep the receipt. If it cannot be shifted, it can be cleared at the pump: the equipment is explosion-proof and safe on a busy forecourt. ## At home around Giants Grave with AdBlue in the diesel tank The warning light had been on for days. A bottle bought at the garage, tipped in at the drive — and it's only at the bin that the cap got your eye. It occurs on drives just off Giants Grave Road as often as anywhere. The point: no miles since leaves it almost as good to finding it at the petrol pump. Diesel and AdBlue keep apart: the AdBlue drops to the floor of that tank and stays put, no matter how long it waits. What to do: leave the keys inside the house so no one moves the vehicle in the morning. Then ring. Your driveway is where it gets drained, whether in Giants Grave or Brynhyfryd. Late-night clears outside a house are fine: the pumps are quiet. ## Giants Grave: drove off with AdBlue in a diesel? A short way after filling up, your motor began playing up: rough running, smoke, lost power, warnings on the dash. Owens Row, perhaps, or the route towards Swansea — a run of under 10 miles. In short: the AdBlue has been sucked into your fuel system. Distance decides how deep it goes: filter and lines first, then the high-pressure pump and each injector. More miles, more restarts: further it travels. Do this: stop anywhere safe, then turn the engine off. Service stations further along are too far: on the M4, under a mile out of Giants Grave, use the next junction. No test restarts: clearing itself isn't something AdBlue will do. Phone, and say what distance the car went. ## Hire, lease or company car with AdBlue in the wrong tank Seven days ago, it was new to you. The AdBlue filler is right next to the diesel one, which you did not know, since your own motor either has no AdBlue or keeps it somewhere else. Anywhere you happen to be in Neath Port Talbot, any driver could slip up. What it means: the same as the scenarios above, depending on whether it's run, with one more stage. Work on your vehicle frequently requires the owner's approval under hire or fleet terms. Next: ring the rental company or the fleet manager first, and then us — settling it before we arrive is faster. Waiting for a reply in the car park outside Briton Ferry, or near Brynhyfryd House? Keep the engine off meanwhile. ## AdBlue in the diesel tank? Not sure, in Giants Grave Honestly, the only answer might be that you think so. What cap came off, you can't say; meanwhile the bottle weighs lighter than it ought to, and ammonia lingers by the filler. Maybe on a friend's drive in Briton Ferry, or rushing by the local primary school on the school run. What it means: a little spilled round your filler does no damage to your motor. If it is inside your diesel tank, though, it does. You cannot tell which by turning the ignition, and doing so would draw in any AdBlue that is in the tank. What to do: treat it as if it was put in. Do not start it. Tell us what you saw on the phone. A clean tank checked is a better outcome than a run one drained. ## Every AdBlue drain around Giants Grave shares these steps Whichever scenario you are in, the job starts the same way. We come to your car, whether it is at a forecourt, a driveway, the car park outside The Puddlers Arms or a side street near Vernon Place Community Hub, and ask three things: what was put in, roughly how much, and if the motor has run. Over the phone, before dispatch, you are told the price, and those answers decide the job too. AdBlue forms crystals and eats at certain metals in fuel systems, so it won't wash out unaided; that is why a full flush, after the drain, counts far more with AdBlue than with petrol. Then comes the filter — cleaned, or replaced where needed — followed by clean diesel, and a test of the car. Never started? In that case roughly half an hour once we are there covers most jobs. Firing it up comes at the end. Our engineers check it runs correctly on clean diesel before we leave. The entire job is done where the car is, and when it is caught soon, long-term damage is very uncommon. Paying is that day, never in advance. For your insurer, there is a VAT invoice and a written report from the engineer. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way. ## About Giants Grave, for a moment Giants Grave is a suburban area in Neath Port Talbot, situated near the coast and approximately 5 miles from Swansea.
