--- title: What Now? AdBlue in a Diesel Tank Walmley canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/walmley-west-midlands/ location: Walmley county: West Midlands latitude: 52.540940 longitude: -1.800180 service: AdBlue in a Diesel Tank updated: 2026-10-23 --- # Walmley: AdBlue in the Diesel Tank? Find Your Situation One thing matters most when AdBlue is in a diesel tank, and that is if the motor has been started since. Not run so far? Then leave it that way, whether your car sits — Walmley or Wylde Green. Call 0333 366 0103 with the key and motor both off. In Walmley, that is typically drained and cleaned where it stands. When the motor has been run, stop somewhere safe straight away, then switch it off. It is a larger job, though stage one does not change. Anywhere in West Midlands it happened, one of the cases below fits yours. ## At the pump in Walmley: AdBlue in a diesel 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. Whether Asda, BP or somewhere else in Walmley, the situation is identical. In short: there is no better place to be to spot it. Still inside that tank, and nothing drawn through: that's where the AdBlue is. Next: avoid the urge to start it just to free up the pump. Ring us from the forecourt after your car sits in a space — the staff will lend a hand to push it — then keep the bottle. Draining it right at the pump is fine if it can't be shifted, because the equipment is explosion-proof. ## Walmley, at home: AdBlue in your diesel tank The warning light had been on for days. Only by the recycling, the empty bottle in your hand, did you glance back at the cap you had used on the drive. Houses just off Walmley Road get caught out as often as everywhere else. Meaning? As long as the vehicle has not been driven since, it's close to the pump case. Diesel and AdBlue stay separate: the AdBlue drops to the base of your tank and remains there, no matter how long it waits. Next: keys in the house, and so no one drives your car anywhere at breakfast. After that, ring. Thimble End or Walmley: whichever your driveway is, that's where it gets drained. Late-night clears beside a house are no problem: the pumps are quiet. ## Set off with AdBlue in a diesel in Walmley? A mile or two beyond topping up, your motor started misbehaving: roughness, smoke, lost power, warnings on the dash. Possibly it was on Walmley Close, possibly on the way out towards Birmingham, under 10 miles away. In short: the AdBlue has been sucked into the system. It has been through the filter and the lines and, the further you went, into your high-pressure pump and the injectors. More driving, more restarts: deeper it travels. Next: pick a safe spot, stop, then switch the motor off. Service stations further along can wait: on the M6 Toll, under 3 miles out of Walmley, use the next junction. It will not have cleared, and so there is no point restarting to find out. Phone, and say how far your vehicle was driven. ## AdBlue in the wrong tank: hire, lease and company motors A week ago, it was new to you. The AdBlue filler is right next to the diesel filler, which you did not know, because your own motor either has no AdBlue or keeps it somewhere else. It can happen to anyone, anywhere in West Midlands. The point: just as above, divided by whether it ran, but with one added stage. Plenty of hire and company contracts want the owner to approve work on your car. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before our technicians arrive than after. Leave the car off while the reply comes, whether you are parked at Wylde Green or near Walmley War Memorial. ## Walmley: unsure if it was AdBlue in your diesel tank? Sometimes the fair answer is "I think so". Too light, that bottle; a trace of ammonia near your filler; a hazy memory of which cap. Sound familiar? It might have been on a friend's drive in Sutton Coldfield, or rushing outside The Deanery Church of England Primary School on the school run. Meaning? Drips around the filler never touch your engine at all. Once it is inside your diesel tank, though, it does. You can't tell which by turning the key, and doing so would suck in any AdBlue that is in the tank. Take it that it was put in, and don't start your engine. Call us and describe what you saw; we would rather check a tank that turns out clean than drain one that has already been run. ## The common ground in every Walmley AdBlue drain Every case has the same opening to the work. Forecourt, driveway, The Fox's car park or a street by Walmley Library & Community Hall — the van comes to the vehicle, and three questions come next: which liquid, which amount, and whether it ran. Your price comes over the phone, before a van leaves, and those answers set the work. Then that tank is emptied and the fuel system rinsed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't rinse out on its own. Finally come your filter, flushed or replaced if necessary; clean diesel; and a test of the vehicle. If the engine has not run, the majority of jobs take about half an hour once we're there. Starting the engine comes last. We make sure it runs correctly on fresh diesel before we go. The whole job is done where your car is, and when it's spotted quickly, long-term damage is very rare. Payment is that day, never upfront. For your insurer, there is a VAT invoice plus a report from the engineer. Dig out your insurance before we arrive: cover for misfuelling is built into many policies. ## About Walmley itself Walmley is a suburban area in the West Midlands, situated near the River Tame and approximately 6 miles northeast of Birmingham city centre. Walmley occupies a relatively low-lying position at around 116 metres above sea level, with the surrounding landscape dominated by residential development. Walmley is characterised by its predominantly detached housing stock, with nearby neighbourhoods including Thimble End and Pype Hayes. ## AdBlue drains across West Midlands, Walmley included Being a residential suburb, Walmley shares its vans with the nearby towns — Tyburn, Pype Hayes — all the way across B postcodes. Quickest of all: a B76 1 postcode to show where you stand. Parked heading to Jones's Wood, or bang in the centre of Walmley, your vehicle stays where it is — there is no need to move it at all. Our engineers drain the car where it is. If you're somewhere hard to explain, near Blue Plaque: The first Walmley Almshouses 1863 or close to a border, ring and ask instead of guessing. ## Your scenario, in one line If it hasn't started, phone and keep it off. Already run: stop, switch off and call. Either way, Petrol in Diesel takes it from there around Walmley and anywhere around West Midlands on 0333 366 0103.
