--- title: Swaffham: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/swaffham-norfolk/ location: Swaffham county: Norfolk latitude: 52.648670 longitude: 0.688550 service: AdBlue in a Diesel Tank updated: 2026-10-23 --- # What Now? AdBlue in the Diesel Tank in Swaffham 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 your car is in Swaffham itself or out in North Pickenham. Switch nothing on, ring 0333 366 0103, and expect a proper flush after a drain, done just where the vehicle sits in Swaffham. When the motor has run, pull in safely straight away, then turn the car off. The job is bigger, but the first stage is the same. Find the scenario below that matches yours, wherever around Norfolk it happened. ## On a Swaffham forecourt with AdBlue in a diesel Imagine it: standing by the petrol pump, holding the nozzle, you spot the cap you opened wasn't the correct one. It could be the BP, or perhaps the Shell, or another forecourt in Swaffham. The upshot: of every spot to notice, this is the best. Still in your tank, and no fuel drawn onwards: that's where the AdBlue is. Do this: stay out of the driver's seat, even if the queue wants freeing. Have the attendants to help rolling it into a bay, save the receipt, then phone us from there. Emptying it there at the pump is possible when it cannot be moved, since the equipment is explosion-proof. ## AdBlue in the diesel tank on a Swaffham drive? For days the dash had been warning you. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look a second time at the cap. Right off Lynn Street is no different from anywhere. Meaning? Provided your vehicle hasn't moved since, it is close to the forecourt case. AdBlue doesn't mix with diesel; it sinks to the bottom of your tank and waits there. Overnight does not change that. Keep your keys indoors tonight — otherwise a person might take it off at breakfast — then phone us. Our technicians drain it on your driveway, whether that's in Swaffham or out in Tumbler Hill. The pumps are quiet enough to use outside a house at night. ## AdBlue in a diesel and already driving around Swaffham? Lumpy running, smoke, lost power or a lit dashboard arrived a mile or two after the top-up. Anywhere along Station Street or else heading to Ely — under 25 miles away. The point: the system has drawn AdBlue in already. Mileage decides how deep it goes: filter and pipework first, then the injection pump and each injector. More driving, more restarts: deeper it travels. What to do: pull over where it is safe then switch off. Services farther along are too far: on the M11, under 50 miles out of Swaffham, use the first junction. It won't have cleared, so there is no sense starting it again to check. Roughly what distance had it go? Tell us as you phone. ## Hire, lease or company car with AdBlue in the wrong tank It's a motor you have had for a week. The AdBlue filler is right beside the diesel one, which you didn't know, since your own motor either has no AdBlue or keeps it somewhere else. Anyone, wherever across Norfolk, might make the same. The point: exactly as above, divided by whether it ran, but with an added stage. Many hire and company contracts need the owner's approval for repairs. Settling it before we turn up is quicker, so phone the rental company or your fleet manager, then us. Waiting for an answer in the car park outside the nearest station, or beside Swaffham War Memorial? Leave your car off throughout. ## AdBlue in the diesel tank? Not sure, in Swaffham "I think so" is often as honest answer there is. What cap was taken off, you can't recall; meanwhile the bottle feels lighter than it ought to, and a whiff of ammonia lingers by your filler. Perhaps it happened in a hurry at the school gates at Sacred Heart Catholic Primary School, Swaffham, or on a friend's drive in South Acre. The upshot: your engine is not harmed by a little AdBlue spilled around the outside. Once it is inside your diesel tank, though, it does. Any AdBlue in that tank would be drawn in by turning on the car, and the start would not settle which it is in any case. What to do: treat it as if it went in. Do not fire it up. Call us and describe what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run. ## Every AdBlue drain in Swaffham shares these stages Whichever scenario you are in, this job starts the same way. Forecourt, drive, The Red Lion's car park or a road beside The Shambles — our van reaches your car, and three answers come next: which liquid, what quantity, and whether it has run. Over the phone, before dispatch, you hear our quote, and those answers shape the work too. AdBlue crystallises and is corrosive to some metals in fuel systems, so it won't wash out on its own; that's why a full flush, after this drain, counts far more with AdBlue than with petrol. Finally are the filter, flushed or renewed as needed; fresh diesel; and a test of the vehicle. The majority of unstarted cars are a half-hour visit after the moment our technicians arrive. Lastly, our engineers start the engine. With new diesel in, it runs while our technicians check it's running smoothly, and then we go. Permanent damage is very rare if it is caught soon, and the entire job is done where the vehicle is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Worth knowing: many insurers include misfuelling cover, so a check of your documents as we travel pays. ## About Swaffham and where it is Swaffham is a town in the eastern part of Norfolk, situated inland at an elevation of around 75 metres.
