--- title: AdBlue in a Diesel Tank South Molton? Next Steps canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/south-molton-devon/ location: South Molton county: Devon latitude: 51.017920 longitude: -3.833780 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # South Molton: AdBlue in the Diesel Tank? Find Your Situation Has your engine turned over since the AdBlue went in? This single question settles nearly everything about what comes next. Out in George Nympton or right in South Molton, an unrun engine should remain that way. Switch nothing on, phone 0333 366 0103, then expect a proper flush plus a drain, done right where your vehicle stands around South Molton. Pull over the moment it is safe then turn off, if it has been run. It's a larger job, yet step one does not change. Further down: the cases we see, anywhere in Devon. Choose the one that fits. ## At the pump around South Molton: AdBlue in a diesel The cap you opened was the wrong one — and you only notice it as you are stood at the petrol pump, bottle or nozzle in hand. It might be the Esso, or the Murco, or another station around South Molton. What it means: this is the ideal place to find out. The AdBlue is inside the tank and nowhere else. Nothing has pulled it in. What to do: do not get back in and fire it up to clear the pump. Phone us from the forecourt after your vehicle is in a bay — the staff will lend a hand to push it — and save the receipt. If it cannot be shifted, it can be emptied at the pump: the equipment is explosion-proof and safe on a busy forecourt. ## At home around South Molton with AdBlue in your diesel tank On your dash, a warning had been lit for days. A bottle bought at the garage, tipped in at the drive — and it was only by the recycling that the cap got a second look. It takes place on driveways just off Broad Street as regularly as anywhere. Meaning? As long as the car has not moved since, it's second to the pump case. Diesel and AdBlue keep apart: the AdBlue settles to the base of that tank and stays there, however long the night. Your move: keys indoors, so nobody drives your car off first thing. Then, ring. Grilstone or South Molton: wherever your driveway is, that is where it gets cleared. Our pumping kit runs quietly enough that it won't wake the neighbours at night. ## AdBlue in a diesel and already driving around South Molton? 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. Duke Street, perhaps, or the route to Exeter — a trip of under 25 miles. Meaning? The pump has taken the AdBlue up. It's been through the filter and the lines and, the further you went, into the high-pressure fuel pump and the fuel injectors. More driving, more starts: deeper it goes. What to do: pull over where it is safe then switch off. On the M5, under 25 miles from South Molton, that means the next exit, not the services further on. Starting it again to test gets nothing — AdBlue never clears itself. Let us hear the mileage driven as you call. ## Hire, lease or company car with AdBlue in the wrong tank Seven days ago, the car was new to you. Your own car either has no AdBlue or keeps it somewhere different, so nothing warned you the AdBlue cap was just next to your diesel. Anywhere you happen to be in Devon, any motorist could be caught. What it means: the same as the situations above, depending on whether it's run, with one more step. Plenty of hire and company agreements want the owner to approve work on the vehicle. What to do: call the hire firm or your fleet manager first, then us. That's faster settled before our engineers turn up than after. Keep the vehicle switched off while the reply comes, whether you are parked at Kings Nympton or close to South Molton Museum. ## South Molton: unsure if it was AdBlue in your diesel tank? At times, "I think so" is the most you can truthfully say. A faint ammonia whiff hangs near your filler, the bottle feels too light, and the cap you took off is a blur. Perhaps it happened in a hurry at the school gates at South Molton Community Primary School, or on a friend's drive in Alswear. Meaning? Drips outside the inlet don't reach your motor at all. AdBlue inside the diesel tank does. Any AdBlue in the tank would be sucked in by starting the car, and the start would not settle which it is in any case. Next: act as though it got in, then leave the engine off. Tell us what you noticed on your phone. A clear tank checked is a happier result than an already-run one emptied. ## The common ground in each South Molton AdBlue drain Whichever scenario you are in, the job starts the same way. Wherever the car is — Town Arms Hotel's car park, a road by South Molton Library, a driveway, a forecourt — our van gets there and we ask for the liquid, the amount, and if the engine has been run. Those answers decide the work, and you hear the price by phone, before anyone heads out. Emptying your tank comes next, followed by a full flush — more vital after urea than after petrol, because crystals and corrosion won't go on their own, however long it sits. 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. Starting it comes last. Our test that it runs smoothly on new diesel comes before we head off. Our engineers do the entire job where the car is, and lasting damage is very unusual if it has been noticed early. Payment is that day, never upfront. For the insurer, you get a VAT invoice and a written report from the engineer. Dig out your insurance before we're en route: cover for misfuelling comes included in many policies. ## About South Molton itself South Molton is a town in north Devon, situated on the River Mole and surrounded by rolling hills.
