--- title: AdBlue in a Diesel Tank Monkswood: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/monkswood-midlothian/ location: Monkswood county: Midlothian latitude: 55.865160 longitude: -3.061360 service: AdBlue in a Diesel Tank updated: 2026-10-18 --- # AdBlue in the Diesel Tank in Monkswood, and What to Do Next What to do about AdBlue in a diesel tank comes down to one thing more than any other: if your engine has been run since it was put in. Out in Lothianbridge or here in Monkswood, an unstarted engine must remain unrun. Switch nothing on, phone 0333 366 0103, and count on a proper flush plus a drain, carried out just where your car stands around Monkswood. Already run? Stop when safe, then turn everything off. Stage one remains the same, even if the job is bigger. Match what happened to a situation from the list below, anywhere around Midlothian you are. ## AdBlue in a diesel on a Monkswood forecourt Only at this point, bottle yet in hand, you realise that the cap you opened was the wrong one, right at the pump. It could be the Shell, or perhaps the BP, or a different forecourt in Monkswood. What it means: this is the best spot to find out. Still in your tank, with no fuel pulled through: that is where the AdBlue sits. What to do: do not get back in and crank it to clear the petrol pump. Ask the staff to help you push your car into a parking spot, keep your receipt or the bottle, then ring us from the forecourt. Emptying it there at the pump is possible if it cannot be shifted, because the equipment is explosion-proof. ## At home in Monkswood with AdBlue in your diesel tank On the dash, a warning had been lit all week. Only by the recycling, the empty container in hand, did you glance back at the cap you'd used on the drive. Right off Third Street is no different from any other place. Meaning? Provided your car has not moved since, it is close to the forecourt case. On the floor of the tank sits where AdBlue stays, since it will not mix with diesel — and a night going by changes nothing of the difference. Keep the keys indoors overnight — otherwise a person may take it off at breakfast — then phone us. Our engineers drain it on your driveway, whether that is around Monkswood or out in Newtongrange. Even at night, our pumps stay quiet enough for a driveway. ## AdBlue in a diesel and already driving around Monkswood? Topped up, pulled away, and before long your motor was running roughly, smoking, down on power, or lighting up your dash. Maybe driving for Edinburgh, under 10 miles away, or just down The Square. Meaning? Your pump has taken the AdBlue in. It has been through your filter and your lines and, the further you went, into the high-pressure fuel pump and the fuel injectors. Every restart, like every mile, carries it deeper. What to do: pull over where it is safe to do so and switch off. Leave at the next junction — not the services further along — if you are on the M8, under 15 miles from Monkswood. Do not restart it to see if it has cleared; it will not have. Tell us know the mileage covered as you call. ## A hire or company car with AdBlue in the wrong tank? It is a car you have had for a week. On your own car, AdBlue is absent or elsewhere. On this one, its inlet is right by the diesel cap — a surprise to you. Throughout Midlothian, no one is immune. In short: an extra stage on top of the cases above, and those turn on if it's run. Many hire and company contracts want the owner to approve work on the vehicle. Sorting it before we turn up is quicker, so phone the rental company or your fleet manager, then us. Stranded near Newbattle Congregational Church or outside Newtongrange till the firm replies, the vehicle remains switched off throughout. ## Not sure it was AdBlue in the diesel tank, Monkswood? "I think so" is sometimes as honest answer there is. A faint ammonia smell lingers near the filler, the bottle feels too light, and the cap you took off is a blur. A rushed top-up by the gates of the local primary school, or a visit to a friend in Mayfield: either fits. Meaning? Drips outside the filler never reach the engine at all. A diesel tank with AdBlue in it is another story. If there is AdBlue in your tank, turning on your car would draw it in, and it would not tell you which either. Assume it got in, and don't start your key. Phone and give what you saw: we would rather find a tank free of AdBlue than empty one after your motor has been run. ## Monkswood: what every AdBlue drain has in common The job begins identically, whichever the case. Wherever your vehicle stands — The Dean Tavern's car park, a road by Newtongrange Library, a driveway, a filling station — our van gets there and we ask about the liquid, the quantity, and if the engine has turned over. Those answers decide this work, and you get our quote on the phone, before anybody sets off. AdBlue crystallises and is corrosive to some metals in fuel systems, and so it won't rinse out on its own; that is why a full flush, after this drain, matters far more with AdBlue than with petrol. Finally are the filter, flushed or renewed as needed; clean diesel; and a check of the vehicle. If the engine has not run, most jobs take about half an hour once we're there. The final step is starting the engine. Our technicians make sure it runs smoothly on new diesel before we leave. Long-term damage is very uncommon when it's noticed early, and the entire job is done where your car is. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, no money upfront. Many insurance policies cover misfuelling, and so look at yours as we head over. ## About Monkswood, briefly Monkswood is a suburban area in Midlothian, situated inland at an elevation of 108 metres, approximately 7.8 miles from Edinburgh.
