--- title: What Now? AdBlue in a Diesel Tank Melksham Forest canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/melksham-forest-wiltshire/ location: Melksham Forest county: Wiltshire latitude: 51.383430 longitude: -2.126220 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # AdBlue in the Diesel Tank in Melksham Forest: What Now? Everything hinges on one detail: whether the engine has started after the AdBlue went in — far more than anything else. Not started yet? Then leave it like that, wherever the vehicle is — Melksham Forest or Shaw. Normally this means draining and properly cleaning it right there around Melksham Forest — and so leave the key and motor off and ring 0333 366 0103. When your engine has been run, pull in safely straight away, then switch it off. Step one stays the same, even though the work is bigger. Wherever across Wiltshire it took place, one of the situations below matches yours. ## AdBlue in a diesel on a Melksham Forest forecourt You're at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. It could be the Texaco, or the BP, or a different station in Melksham Forest. What it means: this is the ideal location to find out. No pump has drawn it in, and so the AdBlue sits just in that tank. Freeing the pump is no excuse to run it — so do not get back in. Have the staff to lend a hand rolling it into a space, hold on to the bottle, then phone us right there. Stuck beside the petrol pump? Explosion-proof equipment makes a live forecourt sensible, and so we can drain the car where it is. ## At home in Melksham Forest with AdBlue in your diesel tank For days the dash had been nagging you. A bottle from the shop, emptied in at the driveway — and it's only by the recycling that the cap caught a second look. It takes place on driveways just off Woodcombe as commonly as anywhere. In short: if your car hasn't been driven since, it's almost as good as finding out at the forecourt. At the floor of that tank is exactly where AdBlue stays, because it won't mix with diesel — and a night going by changes nothing of the difference. Your move: keys indoors, and so nobody drives your car off first thing. Then, phone. Your driveway is where it is drained, be it in Melksham Forest or Melksham. The equipment runs quietly enough that it won't wake the street at night. ## Set off with AdBlue in a diesel in Melksham Forest? Filled up, drove away, and before long your engine was turning unevenly, blowing smoke, down on power, or lighting up the dash. Possibly it was on Lincoln Green, perhaps on the way out towards Bath, under 15 miles away. Meaning? The pump has sucked the AdBlue up. The high-pressure pump and every injector see it as well on a bigger trip, after the fuel filter and pipework have it. Every restart, like each mile, pushes it deeper. Next: find a safe place, stop, and switch your engine off. Melksham Forest sits under 10 miles from the M4; there, come off at the first junction rather than pressing on for the services. Do not restart the car to see if it has cleared; it will not have. Ring us and say how far you went. ## Hire, lease or company car with AdBlue in the wrong tank You have had the car hardly a week. Your own vehicle either has no AdBlue or puts it elsewhere, so no one warned you the AdBlue inlet was just next to the diesel. Anyone, wherever in Wiltshire, could make the same. Put simply: one extra stage on top of the situations above, which depend on whether it's run. The owner often has to approve the work, under plenty of rental and fleet contracts. Settling it before we arrives is quicker, and so ring the hire company or your fleet manager, and then us. Waiting for a reply at the car park at Melksham, or near Forest Methodist Church? Leave your engine off meanwhile. ## AdBlue in your diesel tank? Not sure, in Melksham Forest At times, "I think so" is the most anyone can honestly say. A slight ammonia whiff hangs around the filler, the bottle feels too light, and the cap you took off is hard to recall. A rushed top-up by the gates of River Mead School, or a call to a friend in Bowerhill: either fit. Meaning? Drips around the inlet never touch your engine at all. AdBlue inside your diesel tank does. Turning on the vehicle cannot tell you which, and if there is AdBlue in the tank it would suck it in. What to do: treat it as if it went in. Don't crank it. Phone with what you saw: we'd rather find a tank free of AdBlue than drain one after your motor has been run. ## The common ground in every Melksham Forest AdBlue drain Whatever the case, a single opening applies. Our engineers come to the car, whether it is on a forecourt, a drive, the car park outside The Pig and Whistle or a side street near Saint Andrews Church Hall, and ask three things: what went in, roughly how much, and if your engine has been run. Those replies decide this work, and you hear the quote on the phone, before anybody heads out. Then that tank is cleared and the fuel system purged thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. If the motor has not run, the majority of jobs take about half an hour once we are there. We fire it up at the end. We check it runs properly on clean diesel before we go. Our engineers do the whole job where the vehicle is, and lasting damage is very rare when it has been spotted early. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of policies include misfuelling, so look at yours while the van travels. ## About Melksham Forest itself Melksham Forest is a suburban area situated on the riverside in Wiltshire, with a mix of semi-detached housing and other residential properties.
