--- title: AdBlue in a Diesel Tank Wembury? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wembury-devon/ location: Wembury county: Devon latitude: 50.327270 longitude: -4.072910 service: AdBlue in a Diesel Tank updated: 2026-10-03 --- # What Now? AdBlue in the Diesel Tank in Wembury Everything hinges on one fact: if the engine has been run since the AdBlue went in — far more than anything else. If it has not, keep it that way, whether the vehicle is in Wembury itself or out in Gabber. Usually this is emptying and properly flushing it on the spot around Wembury — so leave the key and engine off and phone 0333 366 0103. If it's run, stop as soon as it is safe and switch off. Stage one stays unchanged, even though the work grows. Compare your case to a situation from the ones below, anywhere in Devon you are. ## Wembury forecourt: AdBlue in a diesel at the pump The cap you unscrewed was the wrong one — and you just notice it as you're standing at the pump, bottle or the nozzle in your hand. Maybe you're at the Asda, possibly at the Valero, maybe somewhere else around Wembury. What it means: this is the best spot to find out. Just your tank holds AdBlue; not one component past it has drawn it in. Clearing the pump is no excuse to start it — so don't get back in. A few jobs: a push into a bay with the staff assisting, the bottle kept, and a call to us from where you stand. If it can't be moved, it can be drained at the pump: the equipment is explosion-proof and fine on a working forecourt. ## AdBlue in your diesel tank at home in Wembury For days the dashboard had been warning you. A bottle from the garage, emptied in on the drive — and it was just at the bin that the cap got your eye. Drives near Church Road see it as much as any other street. In short: if your car has not been driven since, it's almost as good as finding out at the forecourt. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that. What to do: leave your keys inside the house so no one moves the car in the morning. Then call. Knighton or Wembury: wherever your driveway sits, that is where it gets drained. Our equipment runs quiet enough that it won't wake the neighbours at night. ## On the road in Wembury with AdBlue in a diesel You filled up, set off, and a mile or two later the motor began to run roughly, smoke, lose power or light up the dashboard. It might have been heading for Plymouth, under 5 miles away, or just along Ford Road. Put simply: the AdBlue has been pulled into the system. Through the filter, along the pipework, and — the further the distance — deeper into the high-pressure pump and every injector. It goes further with every mile covered and each restart. Next: pick a safe place, stop, then switch the engine off. Services farther on are too far: from the M5, under 50 miles out of Wembury, use the first junction. Don't restart the vehicle to see if it has cleared; it will not have. About what distance did it gone? Tell us when you call. ## Hire, lease or company car with AdBlue in the wrong tank It's a car you have had for a week. The AdBlue filler is right next to the diesel filler, which you didn't know, since your own car either has no AdBlue or keeps it somewhere else. Anyone, wherever in Devon, might do the same. Meaning? Whatever applies above applies here — run or unrun — and one further step. Work on the vehicle often needs the owner's go-ahead under hire or fleet terms. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before our technicians arrive than after. Leave the car off while the reply comes, even if you're parked outside Plymouth or close to Wembury House. ## Unsure about AdBlue in your diesel tank around Wembury? Now and then, "I think so" is the most anyone can honestly say. What cap came off, you cannot say; meanwhile the bottle feels lighter than it ought to, and a whiff of ammonia lingers by the filler. A hurried top-up by the gates of Wembury Primary School, or a visit to a friend in Staddiscombe: both fit. Put simply: spillage near the filler leaves your motor no harm. AdBlue inside the diesel tank does. You can't tell which by turning the key, and doing so would pull in any AdBlue that is in the tank. Next: assume it went in, and leave the engine off. Tell us what you noticed on the phone. A clean tank checked counts as a better result than a run one drained. ## The common ground in every Wembury AdBlue drain Every situation has the same opening to the work. Three things come once our engineers reach your car — at a forecourt, a drive, a road by St Werburgh or the car park at The Odd Wheel: the fluid, the amount, and whether the motor has been started. The price is given over the phone, ahead of anyone setting off, and those replies shape the work. Then the tank is emptied and the system cleaned thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. If the engine hasn't run, most jobs take about half an hour once we're there. The last step is starting the car. Before our technicians leave, it is tested to make sure it runs correctly on clean diesel. We do the whole job where the car is, and permanent damage is very rare if it has been noticed quickly. For your insurer: the engineer's report and the VAT invoice. For you: payment that day, no money upfront. Worth remembering: lots of insurers include misfuelling cover, and so a quick look at your documents as you wait is worthwhile. ## About Wembury Wembury is a coastal village in south Devon, situated near the city of Plymouth and overlooking the Plymouth Sound.
