--- title: AdBlue in a Diesel Tank Colehall: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/colehall-west-midlands/ location: Colehall county: West Midlands latitude: 52.492240 longitude: -1.787120 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # What Now? AdBlue in the Diesel Tank in Colehall What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the engine has run since it got in. If it has not, keep it that way, whether the car is in Colehall itself or out in Kitts Green. Leave your engine and the ignition off and ring 0333 366 0103; it's usually a drain and a thorough flush, done where the car is in Colehall. Stop the moment it is safe and turn off, if it has been run. Step one remains unchanged, even if the work grows. Wherever across West Midlands it happened, one of the situations below matches yours. ## At the petrol pump around Colehall: AdBlue in a diesel The cap you unscrewed was the wrong one — and you just notice it as you're stood at the pump, bottle or the nozzle in your hand. Whether Jet, BP or somewhere else around Colehall, the situation is identical. What it means: this is the best location to find out. No pump has pulled it in, so the AdBlue stays only inside that tank. What to do: don't get back in and start the car to clear the pump. A few things: a push into a space with the staff assisting, the bottle kept, and a call to us from where you stand. Draining it there at the pump is possible if it can't be shifted, since the equipment is explosion-proof. ## Colehall, at home: AdBlue in the diesel tank The warning light had been on for days. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look again at the cap. Driveways near Watland Green see it as much as anywhere. Meaning? Provided the car has not moved since, it's close to the forecourt case. On the floor of your tank sits where AdBlue waits, because it won't blend with diesel — and a night passing makes nothing of the difference. What to do: leave the keys inside the house so no one moves the car in the morning. Then ring. Your drive is where it gets emptied, whether in Colehall or Glebe Farm. Night-time drains beside a house are fine: the pumps are low-noise. ## Colehall: set off with AdBlue in a diesel? Rough running, smoke, falling power or a glowing dashboard arrived a short way after the top-up. It might have been driving to Birmingham, under 10 miles away, or just along Cole Hall Lane. The upshot: your system has pulled AdBlue in by now. Distance decides how deep it goes: filter and pipework to begin with, then the injection pump and each injector. It goes deeper with every mile covered and every restart. What to do: pull over where it's safe then switch off. Exit by the first junction — not the services beyond — if you are on the M6, under 3 miles from Colehall. Do not restart the vehicle to see if it has cleared; it will not have. Ring us and say how far you travelled. ## AdBlue in the wrong tank: hire, lease and company motors It is a car you have had for a week. On your own vehicle, AdBlue is absent or elsewhere. On this one, its cap is just by your diesel inlet — news to you. It can happen to anyone, anywhere around West Midlands. Meaning? Whichever case above applies too — run or unrun — plus one extra step. Plenty of hire and company agreements want the owner to approve work on the car. Next: ring the hire company or your fleet manager first, and then us — sorting it before we arrive is quicker. Keep it switched off while the answer comes, whether you are waiting at Lea Hall or near Glebe Farm Public Library. ## Colehall: unsure whether it was AdBlue in your diesel tank? "I think so" is often the most honest as it gets. Too light, the bottle; a hint of ammonia near the filler; a hazy memory of which cap. Look familiar? It might have been at a friend's drive in Lea Hall, or rushing by Audley Primary School at the school run. In short: a spill near your filler does the engine unharmed. The diesel tank with AdBlue inside is another matter. You cannot tell which by turning the ignition, and doing so will pull in any AdBlue that is in the tank. Assume it went in, and never start your key. Ring us and describe what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run. ## Every AdBlue drain around Colehall shares these steps The work begins identically, whichever the case. Three things are asked when our technicians reach the car — on a filling station, a drive, a road beside Shard End Library or the car park outside The Brook Meadow: the fluid, the quantity, and whether it has run. The price is given over the phone, ahead of anyone setting off, and the replies set the job. Draining your tank comes first, then a full flush — more important after urea than after petrol, because crystals and corrosion won't go by themselves, however long you wait. Clean diesel goes in after your filter has been cleaned or changed, and the car is finally checked. The majority of unstarted vehicles are a half-hour visit after the moment our technicians turn up. The last step is firing it up. With clean diesel in, it runs while our engineers confirm it's running correctly, and then we go. The whole job is done where your car is, and when it's caught soon, permanent damage is very rare. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many policies include misfuelling, so look at yours while the van travels. ## About Colehall Colehall is a suburban area located on the riverside in the West Midlands, with an elevation of around 100 metres.
