--- title: Dreghorn: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/dreghorn-city-of-edinburgh/ location: Dreghorn county: City of Edinburgh latitude: 55.905010 longitude: -3.238860 service: AdBlue in a Diesel Tank updated: 2026-10-11 --- # What Now? AdBlue in the Diesel Tank in Dreghorn Everything hinges on a single fact: if your engine has started after the AdBlue was added — far more than anything else. Anywhere your car stands — Bonaly, Dreghorn — don't run an engine that hasn't been started yet. Switch nothing on, ring 0333 366 0103, then expect a proper flush after a drain, carried out right where the vehicle sits around Dreghorn. When the engine has run, stop safely straight away, then turn the vehicle off. A larger job, yes, yet the identical first step. Further down: the cases our engineers meet, anywhere across City of Edinburgh. Pick the one that fits. ## Dreghorn forecourt: AdBlue in a diesel at the pump Picture it: standing by the pump, gripping the nozzle, you realise the filler you took off wasn't the right one. Anywhere in Dreghorn, then — Tesco, Shell, or anywhere else close by. Meaning? Finding out on the forecourt is the best it gets. Just your tank has AdBlue; not one part beyond it has taken it in. Your move: keep out of the car, however much the pump wants clearing. A few things: a push into a space with the attendants assisting, the receipt kept, and a call to us from the forecourt. Stuck by the petrol pump? Explosion-proof kit keeps a live forecourt sensible, and so we can drain the car in place. ## Dreghorn, at home: AdBlue in the diesel tank On the dash, a reminder had been lit all week. A bottle from the garage, emptied in on the drive — and it was just by the recycling that the cap got your eye. Homes just off The Gallolee get caught out as much as anywhere else. Meaning? As long as the vehicle hasn't moved since, it's close to the pump case. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight doesn't change that. What to do: leave the keys inside the house so no one moves the vehicle in the morning. Then ring. Your drive is where it gets emptied, be it around Dreghorn or Oxgangs. Even at night, the pumps stay quiet enough for a driveway. ## On the road in Dreghorn with AdBlue in a diesel You filled up, set off, and a mile or two later the engine began to run roughly, smoke, lose power or light up the dashboard. Perhaps it was on Redford Road, perhaps on the way out towards Edinburgh, under 5 miles away. Meaning? The fuel pump has sucked the AdBlue in. It's been through the fuel filter and the lines and, the further you went, into the high-pressure pump and the fuel injectors. More miles, more starts: further it goes. Stop somewhere safe — that is the first step — then turn it off. Exit at the first junction — not the services beyond — if you're on the M8, under 5 miles from Dreghorn. No trial starts: clearing isn't something AdBlue does. Roughly how far did it go? Say so as you call. ## AdBlue in the wrong tank of a hire, lease or company car A week ago, the car was new to you. Your own motor either does without AdBlue or keeps it somewhere different, and so nothing warned you the AdBlue cap was just next to the diesel. Throughout City of Edinburgh, nobody is immune. What it means: the same as the situations above, depending on whether it has run, with one more step. Plenty of hire and company contracts want the owner to approve work on your car. Do this: rental firm or your fleet manager first, us next, because sorting it beforehand saves time. Stranded by Covenanters Monument or at Kingsknowe till someone answers, your car stays switched off the whole time. ## Unsure about AdBlue in the diesel tank around Dreghorn? At times the honest answer is "I think so". Which cap came off, you cannot say; but the bottle weighs less than it ought to, and a whiff of ammonia hangs by your filler. A hurried top-up by the gates of the local primary school, or a visit to a friend in Hailes: both fit. The point: the motor isn't hurt by some AdBlue spilled on the outside. A diesel tank with AdBlue inside is a different story. Any AdBlue in that tank will be drawn in by firing up your car, and the start would not settle which it is in any case. What to do: treat it as if it was put in. Do not crank it. Phone with what you saw: we'd sooner confirm a tank free of AdBlue than drain one after your engine has run. ## What each AdBlue drain in Dreghorn has in common Whatever the situation, a single opening applies. Our engineers come to your car, whether it's on a forecourt, a driveway, the car park outside Colinton Inn or a side street close to Covenanters, and ask three things: what got in, about how much, and whether the engine has run. Your price is given over the phone, before a van leaves, and the answers shape the work. AdBlue crystallises and is corrosive to certain metals in fuel systems, so it won't rinse out unaided; that's why a full flush, after the drain, counts much more with AdBlue than with petrol. Next is the filter — cleaned, or swapped when necessary — then clean diesel, and a test of your vehicle. Not started? Then about half an hour on site covers most jobs. Our technicians start it last. We confirm it runs smoothly on new diesel before leaving. The entire job is done where the car is, and if it's spotted early, long-term 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 cover misfuelling, and so check yours while the van travels. ## About Dreghorn Dreghorn is a suburban area located on the outskirts of Edinburgh, sitting near the River Almond in the City of Edinburgh.
