--- title: What Now? AdBlue in a Diesel Tank Wadingburn canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wadingburn-midlothian/ location: Wadingburn county: Midlothian latitude: 55.882140 longitude: -3.124730 service: AdBlue in a Diesel Tank updated: 2026-10-15 --- # What Now? AdBlue in the Diesel Tank in Wadingburn Has your engine turned over since the AdBlue got in? That one question decides nearly everything else from here. Over in Bonnyrigg or here around Wadingburn, an unstarted motor should remain unrun. Switch nothing on, ring 0333 366 0103, and expect a proper flush plus a drain, done right where the car sits around Wadingburn. Already started? Stop when safe, then turn it off. A larger job, then, but the same first move. Find the situation below that matches yours, wherever around Midlothian it happened. ## On a Wadingburn forecourt with AdBlue in a diesel You are 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 Tesco, another forecourt nearby or anywhere else in Wadingburn, the case is identical. What it means: this is the best location to find out. Nothing has pulled it through, and so the AdBlue stays only in your tank. Do this: stay out of the driver's seat, even if the pump needs clearing. Ask the attendants to help you roll the vehicle into a parking space, keep the till receipt or the bottle, and ring us from the forecourt. If it can't be moved, it can be drained at the pump: the equipment is explosion-proof and fine on a working forecourt. ## AdBlue in your diesel tank at home in Wadingburn For days the dashboard had been nagging you. A bottle bought at the shop, tipped in at the driveway — and it was only by the bin that the cap caught your eye. It occurs on drives just off Green Lane as frequently as anywhere. The upshot: zero miles since leaves it almost as good to spotting it at the petrol pump. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that. Next: prevent any early move by keeping the keys indoors, then ring us. Broomieknowe or Wadingburn: wherever your drive is, that is where it gets drained. Even at night, our pumps stay quiet enough for a residential street. ## On the road around Wadingburn with AdBlue in a diesel You filled up, set off, and a mile or two later your engine began to run roughly, smoke, lose power or light up the dashboard. Glebe Place, say, or the route to Edinburgh — a trip of under 10 miles. The point: your system has drawn AdBlue in already. It's been through the fuel filter and the lines and, the further you went, into the high-pressure fuel pump and your injectors. More driving, more restarts: deeper it goes. Pull in somewhere safe — that's the next step — then turn everything off. Leave at the next junction — not the services beyond — if you're on the M8, under 10 miles from Wadingburn. No trial restarts: clearing is not something AdBlue will do. Tell us know the mileage covered as you ring. ## A hire or company car with AdBlue in the wrong tank? It is a vehicle you have had for a week. Your own car either has no AdBlue or puts it somewhere different, so nothing told you the AdBlue cap was right beside the diesel. Anyone, wherever across Midlothian, might make it. The upshot: exactly as above, split by whether it ran, but with an added step. The owner often has to sign off the work, under many rental and company agreements. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before our engineers turn up than after. Stuck by Lasswade Old Kirkyard or outside Eskbank until the firm answers, your vehicle remains switched off the whole time. ## Wadingburn: unsure whether it was AdBlue in your diesel tank? "I think so" is sometimes the most honest as it gets. A slight ammonia-like smell lingers around the filler, the bottle seems too light, and the cap you took off is a blur. Maybe at a friend's drive in Eldindean, or in a rush outside the local primary school at the school run. Put simply: a spill round your filler does your engine unharmed. Inside your diesel tank, by contrast, AdBlue damages it. Any AdBlue in your tank will be pulled in by starting your car, and the start wouldn't settle which it is in any case. Take it that it got in, and never turn your key. Ring and give the details: we'd rather confirm a clean tank than empty one once your engine has been run. ## Wadingburn: what each AdBlue drain has in common Every situation has the same opening to the work. Forecourt, drive, Laird & Dog's car park or a street by The Baird Smith Memorial — our van comes to your car, and three questions come next: which liquid, what amount, and whether it ran. Over the phone, ahead of anything else, you hear our price, and those replies decide the job too. Then your tank is cleared 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 does not rinse out on its own. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Where your engine has not run, allow roughly half an hour on site, for most jobs. Firing it up comes last. Our check that it runs properly on fresh diesel comes before we leave. The entire job is done where your car is, and if it's spotted early, long-term damage is very unusual. Paying is that day, never in advance. For your insurer, there is a VAT invoice and a report from the engineer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we are on the way. ## About Wadingburn and where it is Wadingburn is a suburban area situated on the riverside in Midlothian, with a mix of detached housing and a relatively small population of around 688 residents.
