--- title: What Now? AdBlue in a Diesel Tank Foxhayes canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/foxhayes-devon/ location: Foxhayes county: Devon latitude: 50.725770 longitude: -3.549020 service: AdBlue in a Diesel Tank updated: 2026-10-05 --- # AdBlue in the Diesel Tank in Foxhayes, and What to Do Next One thing counts above all once AdBlue is in a diesel tank, and it is if the motor has run since. If it hasn't, keep it that way, whether the vehicle is around Foxhayes itself or out in St Thomas. Leave the motor and your ignition off then phone 0333 366 0103; it is normally a drain and a thorough flush, done where the car is in Foxhayes. Pull over the moment it is safe then switch off, if it has already run. A bigger job, yes, but the same first step. Further down: the situations our engineers meet, anywhere around Devon. Pick yours. ## At the petrol pump in Foxhayes: AdBlue in a diesel Picture it: standing by the pump, gripping the bottle, you spot the filler you took off wasn't the correct one. Maybe you're at the Esso, possibly at the Sainsbury's, perhaps somewhere else in Foxhayes. Meaning? Finding out here is as good as it gets. Still in that tank, with no fuel drawn onwards: that is where the AdBlue is. Your move: stay out of the driver's seat, however much the pump wants clearing. Ask the staff to help you push your car into a parking bay, keep the receipt or the bottle, and call us from the forecourt. Draining it right at the petrol pump is possible if it cannot be shifted, since the equipment is explosion-proof. ## AdBlue in the diesel tank at home in Foxhayes For days the dashboard had been warning you. A bottle from the garage, tipped in on the driveway — and it was only at the bin that the cap caught your eye. It takes place on driveways just off Exwick Road as commonly as anywhere. The point: no driving since leaves it nearly as good to finding it at the petrol pump. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight doesn't change that. What to do: leave your keys inside the house so nobody moves the vehicle in the morning. Then call. Your driveway is where it gets drained, be it in Foxhayes or Exwick. Late-night drains outside a house are fine: the pumps are quiet. ## Foxhayes: set off with AdBlue in a diesel? Rough running, smoke, lost power or a glowing dashboard arrived a mile or two beyond the top-up. It might have been driving to Exeter, under a mile away, or simply down Camberely Court. Meaning? Your pump has taken the AdBlue in. The high-pressure pump and every injector get it too on a bigger run, after the filter and pipework have it. Each mile and each restart takes it further. Next: pick a sensible place, stop, and turn the engine off. Foxhayes sits under 5 miles from the M5; there, come off at the next junction rather than pushing on for the services. No trial restarts: clearing isn't something AdBlue will do. Roughly how far had it go? Say so when you call. ## AdBlue in the wrong tank of a hire, lease or company car You have just had the vehicle for days. Your own car either does without AdBlue or puts it elsewhere, so nothing warned you the AdBlue inlet sits just next to your diesel. It can happen to anyone, anywhere around Devon. What it means: the same as the scenarios above, depending on whether it has run, with one more step. Plenty of hire and company agreements want the owner to approve work on your car. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before we get there than after. Stranded by Exwick Sports Hub or at Exeter St Davids until the firm answers, your vehicle stays turned off throughout. ## Not sure it was AdBlue in the diesel tank, Foxhayes? Now and then, "I think so" is the most anyone can truthfully say. Lighter, the bottle; a trace of ammonia near your filler; no clear memory of which cap. Sound familiar? The gates of St Gabriel's CofE Primary School in a rush, perhaps, or a friend's drive over in Nadderwater. Meaning? Drips around the inlet don't touch the engine at all. AdBlue inside the diesel tank does. If there is AdBlue in the tank, firing up the vehicle would suck it in, and it wouldn't tell you which either. Do this: behave as though it got in, and don't start the engine. Phone with the details: we'd rather find a tank free of AdBlue than drain one once the motor has run. ## The common ground in each Foxhayes AdBlue drain Whichever situation you are in, this job starts the same way. Three questions come when our engineers arrive — on a filling station, a driveway, a road beside Steve Curley or the car park at The Thatched House: the fluid, the amount, and whether it has been started. Replies shape the job; the price comes by phone whilst nobody has set off yet. Then that tank is cleared and your system flushed 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. Then is the fuel filter — cleaned, or replaced when needed — followed by clean diesel, and a test of your car. Where your engine hasn't been started, expect about half an hour on site, for most cases. We start it at the end. With clean diesel in, it runs while our technicians confirm it is running properly, and then we head off. Long-term damage is very unusual if it is spotted early, and the entire job is done where the vehicle is. Nothing is taken upfront, settlement happens on the day, and you get what the insurer asks for: an engineer report and a VAT invoice. Worth remembering: lots of insurers offer misfuelling cover, so a check of your policy while you wait is worthwhile. ## About Foxhayes Foxhayes is a suburban area located on the outskirts of Exeter in Devon, sitting near the River Exe at an elevation of around 15 metres. Foxhayes forms part of the larger urban area surrounding Exeter, with nearby neighbourhoods including Exwick and Redhills. Foxhayes is characterized by its predominantly terraced housing stock, reflecting the area's history of residential development. ## AdBlue drains round Foxhayes and across Devon Redhills and Exeter get the same vans as Foxhayes, a residential suburb, plus further towns throughout EX postcodes. Fastest of all: a EX4 2 postcode to show where you stand. Centre of Foxhayes or a lay-by near Barley Valley Nature Reserve: either way it is, the car never needs to shift an inch for this drain. The van drains it in place. Assuming doesn't help beside St. Andrew, on a county line or anywhere hard to pin down; ring and ask. ## Your situation, in one line Unstarted? Keep it that way then phone. Run already: stop, power down, ring 0333 366 0103. Petrol in Diesel handles the rest, in Foxhayes or wherever across Devon.
