--- title: Macmerry: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/macmerry-east-lothian/ location: Macmerry county: East Lothian latitude: 55.940580 longitude: -2.907850 service: AdBlue in a Diesel Tank updated: 2026-10-02 --- # What Now? AdBlue in the Diesel Tank in Macmerry What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether the engine has been run since it was put in. Not run yet? Then keep the vehicle that way, whether the car is — Macmerry or Blindwells. Keep nothing on, call 0333 366 0103, and expect a thorough flush plus a drain, carried out right where your vehicle stands in Macmerry. Already run? Pull over once you safely can, then turn it off. A larger job, then, yet the same first move. Wherever across East Lothian it took place, one of the cases below fits yours. ## Macmerry forecourt: AdBlue in a diesel at the pump Just now, bottle still in your hand, it dawns on you that the cap you took off was the wrong one, there at the pump. Be it BP, Asda or anywhere else around Macmerry, the situation is identical. What it means: this is the ideal spot to find out. Just that tank holds AdBlue; no part past it has drawn it in. What to do: do not get back in and fire it up to clear the petrol pump. Three things: a shove into a bay with the staff helping, the bottle saved, and a call to us from the forecourt. Draining it right at the pump is possible when it can't be shifted, since the equipment is explosion-proof. ## AdBlue in your diesel tank at home around Macmerry The warning light had been on for days. Bought a container, tipped it in at home, binned the empty — and only then checked the cap a second time, too late. Drives near Whiteloch Road see it as much as anywhere. Put simply: if the car has not been driven since, it is nearly as good as spotting it at the pump. Diesel and AdBlue stay apart: the AdBlue settles to the floor of your tank and stays there, however long the night. Put the keys indoors overnight — otherwise a person may take it off at breakfast — and phone us. We drain the vehicle on your drive, whether that's in Macmerry or out in Penston. Even at night, our pumps stay quiet enough for a driveway. ## AdBlue in a diesel and already driving around Macmerry? Lumpy running, smoke, falling power or a lit dashboard arrived a short way after the top-up. Anywhere along Robins Neuk or else on the road towards Edinburgh — under 15 miles away. The upshot: the system has pulled AdBlue in by now. Distance sets how far it gets: filter and pipework to begin with, then the high-pressure pump and each injector. It travels further with every mile driven and each restart. Next: pick a safe spot, pull in, then switch the motor off. Service stations farther along can wait: from the M8, under 25 miles out of Macmerry, take the next junction. No test restarts: clearing itself is not something AdBlue will do. Tell us hear the distance driven when you ring. ## AdBlue in the wrong tank of a hire, lease or company car It is a car you have had for a week. On your own vehicle, AdBlue is absent or somewhere else. On this one, the inlet is just by your diesel inlet — a surprise to you. It can happen to anyone, anywhere in East Lothian. What it means: the same as the situations above, depending on whether it has run, with one more step. Plenty of hire and company agreements want the owner to approve work on the car. What to do: ring the hire firm or your fleet manager first, then us. That's quicker settled before our technicians arrive than after. If you're stranded in the car park at Longniddry, or by Lie Forrit, while you wait for an answer, leave the vehicle off. ## Not sure it was AdBlue in the diesel tank, Macmerry? "I think so" is often as honest answer there is. What cap was taken off, you cannot recall; meanwhile the bottle feels less than expected, and a whiff of ammonia hangs by your filler. It might have been on a friend's drive in Gladsmuir, or rushing by the local primary school on the school run. The upshot: the motor isn't harmed by a little AdBlue splashed around the filler. The diesel tank with AdBlue inside is a different matter. You cannot tell which by turning the ignition, and doing so would pull in any AdBlue that is in your tank. Your move: act as though it got in, and never start your engine. Ring with what you saw: we'd rather confirm a clean tank than empty one after the engine has been run. ## Every AdBlue drain around Macmerry shares these steps Each situation gets the same start to the work. We come to the car, whether it's at a forecourt, a drive, the car park outside the pub in the village or a side street near In-gaun-ee, and ask three things: what went in, about how much, and whether the motor has run. Replies set the work; the price follows by phone while nobody has set off yet. A thorough flush comes after this drain. With petrol it is routine; with AdBlue it's crucial, since deposits form and certain metals are attacked, and neither washes away unaided. Last are your filter, flushed or renewed if necessary; fresh diesel; and a check of your vehicle. The majority of unstarted cars are a half-hour visit from the moment our technicians get there. The final step is starting it. Our test that it runs correctly on clean diesel comes before our technicians leave. Lasting damage is very unusual when it's noticed quickly, and the entire job is done where your car is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, nothing in advance. Plenty of insurance policies cover misfuelling, so look at yours while the van travels. ## About Macmerry itself Macmerry is a small village in East Lothian, situated near the coast and approximately 10.9 miles from Edinburgh.
